WIND SECTOR NEEDS TO RESOLVE DATA ACCESS ISSUES IF IT IS PLAY A COMPETITIVE PART IN THE ENERGY TRANSITION The finding of a report by ONYX Insight, a leading provider of predictive data analytics and engineering expertise to the global wind industry - looking at data access and ownership in the wind industry. According to the report, the wind energy sector needs to adopt data sharing practices in other industries such as those used in aviation if it is to compete with fossil fuels and play a fundamental role in the energy transition.

While the wind industry has been quick to adopt digitalisation and predictive maintenance practises, lack of access to data is holding it back from realising the full benefits of this technology. Missing data has the potential to give operators more detailed insights, enabling better asset management, long term O&M planning, and enhancing strategic maintenance.

Unexpected turbine failure contributes to 58% of OPEX costs, the bulk of which is reactive, unplanned maintenance that could have been avoided.

Specifically, improved data sharing could lead to new analytical methods such as the application of Artificial Intelligence (AI) to improve turbine performance. The massive potential of AI is recognised throughout the industry, but these methods have to date been hampered by the lack of clean, cross-platform, normalised data. Improved data sharing has the potential to fully unleash AI and lead to a significant reduction in LCoE (Levelised Cost of Energy) across the renewables sector.

INTERVIEW

A NITHYANAND

BUSINESS HEAD – RENEWABLES, SEMBCORP INDIA

Wind industry must brace the headwinds to stay relevant and play its vital role in India's energy transition.

In an exclusive interview with Wind Insider magazine, Mr. A Nithyanand, Business Head – Renewables, Sembcorp India talks about his perspectives on the role of wind energy in India’s energy transition. He spoke about the challenges and limitations faced by the wind industry. He also threw light on the company’s future plans for the wind sector.

How do you view India's RE journey so far and what are the driving forces?

There should be an urgent effort to upgrade the evacuation network, which has been cited as the reason for the tepid response to new auctions. Repowering the aging, small turbines is an efficient way to expand wind generation, especially since some of the best wind power sites house many low-efficiency turbines. Also encouraging the growth of hybrid projects could help further harness the wind sector’s potential.

Indian RE sector is aggressively pursuing the goal of building a robust cleaner energy portfolio. The renewable energy sector has grown rapidly in the past decade, contributing 8-9% of India’s energy mix, and now is steadily moving towards contributing 15-20% of the country’s contribution in the next 10 years. Speaking of India’s energy mix in the coming decade, and more so for the next level of renewable energy growth in India, we will require a fresh set of impetus and investments.

Despite its many challenges, wind energy in India has a lot to gain from its experience and its large manufacturing base.

Wind industry must brace the headwinds to stay relevant and play its vital role in India's energy transition.

How do you envisage the role of wind energy in the country's energy security, diversification and transition?

There has been severe disruption in the global supply chain over the past year. Renewables industry in India was faced with significant delays in commissioning of projects that rely heavily on imports of critical equipment and material. Despite the near-term hurdles faced last year such as construction work put on hold and cost overruns due to the pandemic, given the volatile global economy, wind and solar sectors in India can still continue to remain attractive to many investors.

Because renewable energy projects are typically backed by long-term contracts and sales are insulated from fluctuations in consumer demand, wind and solar could emerge as preferred investment arenas.

The wind energy sector in India stands at a crossroads today.

There are questions about the sustainability of the current prevailing tariffs. Over the longer term, its competitive position vis-à-vis solar may worsen if costs of solar drop faster and as the best wind sites are taken up Nevertheless, the industry is a mature one, with a large installed capacity and years of operating experience along with a large manufacturing base and skilled human power. The sector needs to explore alternatives such as repowering and hybrid to remain relevant and to expand its scope, in addition to improving efficiencies and cutting costs to retain its competitive edge

ANNUAL ISSUE 2021 | PAGE 12

Given the disruptions over the past year, will India be able to meet the 60-GW wind energy target by 2022?

What are the biggest challenges and limiting factors faced by the RE and wind sector in India?

India's renewable energy sector continues to remain one of the world's largest, fastest growing and most competitive markets

May-June Issue 2021 | Pg 14

on a price parity basis. But, in the current scenario India’s entire 64-gigawatt pipeline of wind and solar projects may experience some degree of delay, depending on the lingering impact the virus has on public health and the economy. For now, it will be a challenge to meet the 2022 target.

One of the foremost issues facing not just the RE or wind space but the power sector as a whole is the frail financial health of discoms. It continues to cause liquidity risks and adversely impact the return on equity of independent power producers.

The easy access to affordable finance has remained another long-standing problem for wind developers in India. Project financing hurdles such as sovereign risks, policy risks and erratic discom payments have from time to time put financial constraints for the Indian renewable energy sector.

A further headwind being faced by the Solar sector is the steep runaway in module prices in 2021. Industry and government will need to collaboratively address this challenge in the interest of the nation.

What are the reforms that are necessary in your view to unlock the next level of growth in the RE and wind power sector?

The next level of RE growth in India, beyond 10% of power generated, wherein wind will have a key role to play, will require a fresh set of reforms. The administration has been receptive to the industry suggestions, and this gives unprecedented opportunity to our policymakers and the industry to work together to try and fix legacy issues and inherent policy bottlenecks.

Beyond the realm of the policies that shape the RE sector, issues such as the number of large and unresolved NPAs in thermal power and discom sector have cast their shadow on the integrity of the Indian financial sector as a whole.

What are Sembcorp's future plans for this sector in the region and in India? What is the current installed wind capacity of Sembcorp Energy and how has been the journey so far?

Our strategic objectives and policies continue to be underpinned by the energy transitions taking place across the world. Globally, Sembcorp continues to actively grow its renewable energy offering as a leading provider of sustainable solutions. Sembcorp Industries now has a renewables portfolio of over 3,000MW in operation and under development across Singapore, China and India. In India, with an investment of USD ~4 billion, Sembcorp is one of the leading independent power generators in India. Over the years we have built a balanced portfolio of conventional and renewable assets totalling approximately 4.8 GW capacity in operation and under construction.

Sembcorp has a wind energy capacity of 1,694 MW. Our successful commissioning of the entire 800MW of generation capacity that we won in our three SECI wind projects is an

ANNUAL ISSUE 2021 | PAGE 13

example of our focus on renewables. With this Sembcorp India now has the largest operational capacity of SECI wind projects in India. As a long-term investor, we take pride in meeting our commitments. These projects have given us confidence in our capabilities, and we are now ready to move into the next phase of our growth journey and participate in future opportunities

Tell us a bit about the recent technology advancements Sembcorp Energy has achieved in the wind power sector?

As an organisation our focus remains on strengthening our capabilities and improving efficiencies. By introducing selfO&M in our renewable business, Sembcorp India is focusing on minimising the production costs per unit of energy generated over the life of the asset (LCOE) by ensuring asset productivity, reliability and accessibility.

Besides strengthening our capabilities, this initiative has helped in improving the turbine performance, increasing safety standards and helping in improving generation by implementing ancillary technologies. Moving to self-O&M in our renewable business has helped in moving our performance indicator from traditional time-based availability to a more scientific energy-based availability, while also helping drive cost benefits with high operational efficiencies.

The introduction of digitization and associated analytics has significantly enhanced our capability for remote monitoring of our renewable energy assets across seven states in real-time.

This analytics based digital tool has brought profound transformation in our operations with significant cost benefits and high performance of our assets.

Further, the pandemic necessitated the introduction of new SOPs and technological solutions. As we learn to safely coexist with covid, in addition to operational efficiencies, the industry will have to increasingly prioritize its digital transformation and long-term resilience diligently, to mitigate and manage risks more efficiently.

How has the Covid-19 crisis impacted the company’s operations and what steps are being taken to mitigate its impact and ensure safety?

The safety and well-being of our employees is our top priority in Sembcorp. Quite early in the pandemic we adopted new standard operating procedures (SOPs) and technological solutions for remote working. Introducing them in March 2020 ahead of the lockdown last year helped us keep our sites fully operational. The pandemic accelerated our adoption and integration of digital technology and enhanced our capability to monitor, forecast and run our operations efficiently. At the present time, all our personnel are taking full precautions to ensure site operations remain unaffected by the pandemic.

With the number of cases being exponential this time, we are ensuring strict implementation of the SOPs introduced last year. In addition to staying compliant with COVID protocols, we continue to collaborate with local administration and health officials to ensure safe and effective measures are in place for maintaining essential power supply.

OFFSHORE WIND ASSESSMENTS INCREASING COVERAGE, ACCURACY AND EFFICIENCY IN

WITH DUAL SCANNING LIDAR

J. Schneemann for University of Oldenburg

As the global economy continues embracing clean, renewable energy, the promise of offshore wind is set to propel the future of electricity generation forward.

With the offshore wind industry and the technologies used therein continuing to mature and evolve, turbines are growing in size and providing more power capacity than ever. While these advances deliver significant performance and cost improvements, understanding wind resources in complex offshore environments is only becoming more challenging.

With challenges stemming from taller wind turbines and the development of larger wind farms in increasingly deep waters, determining where the abundant wind resources exist, understanding their characteristics and validating their quality remains important to the success of any offshore project. To better understand what the wind is doing at a given site, developers and operators are beginning to turn to lidar technology innovations to bolster wind data collection, minimize costs, accelerate projects and ensure optimal operational continuity.

ANNUAL ISSUE 2021 | PAGE 14

To better understand what the wind is doing at a given site, developers and operators are beginning to turn to lidar technology innovations to bolster wind data collection, TWO IS BETTER THAN ONE Assessing and characterizing available wind resources is critical before the first turbine is constructed and the first watt of energy is ever produced. By measuring the full wind regime and characteristics of the wind flow, scanning lidar provides comprehensive, spatial wind data at ranges up to approximately 15 kilometers. It is being used more frequently for offshore Wind Resource Assessment (WRA) to provide bankable wind data, particularly when there are opportunities to place it near the shoreline or on an offshore platform.

minimize costs, accelerate projects and ensure optimal operational continuity."

Supported by growing acceptance among major independent experts, developers, financiers and regulatory bodies, scanning lidar helps project owners and operators accurately define, measure and forecast offshore wind resources, ensuring their wind farm is not just technically feasible but financially sound.

Accurate wind measurement is critical to bankable WRA, as imprecise data can result in unfavorable financing conditions or the selection of the wrong type of equipment. WRA can be especially challenging in nearshore locations with complex wind phenomena and busy waterways that serve various industries – dual lidar solves this challenge and brings exceptional value to these types of campaigns.

In much the same way that a single scanning lidar delivers abundant data from one strategically situated location, a dual scanning lidar solution increases the coverage, accuracy and efficiency of offshore WRAs by observing an offshore location from several positions.

This simultaneous deployment of two scanning lidars empowers owners and operators with accurate wind mapping information, which significantly increases the quantity and quality of wind data. Dual scanning lidar leverages intersecting beams at multiple locations to provide a dense network of measurement points and ultimately reduce vertical and horizontal uncertainty.

Whether developing or operating an offshore wind project, assessing and characterizing available wind resources is vital. Fortunately, new techniques for using current technologies — such as dual scanning lidar — are delivering a richer understanding of offshore wind resources and greater campaign cost-effectiveness. From improved wind data reliability to reduced uncertainty in the assessment of wind resources, dual scanning lidar delivers a range of benefits that ultimately make harnessing the power of the wind in increasingly complex offshore environments easier than ever.

WHAT ARE THE BEST PRACTICES & TECHNICAL INNOVATIONS

IN WIND POWER OPERATION AND MAINTENANCE?

In India, as wind is being considered as one of the key resources for power generation, the subject of wind project operation and maintenance (O&M) is becoming increasingly important. Wind power technology is one of the major growing areas in the Indian energy sector.

Experts say O&M is the gamut of entire asset management of wind power plants to provide safe and secure net to the customer’s assets. O&M is a financial perspective with optimising costs, improving reliability of the wind power plant and maximisation of yield by implementing O&M strategies and using IT and data analytics.

The overall objective of having a well set O&M system in place is to increase the availability of wind power systems along with a cost effective life cycle that together will benefit in establishing and strengthening the competitiveness of wind power on the energy market.

Let’s read what the experts have to say about the best practices and technical innovations in wind power operation and maintenance.

Satish Subbarao Head - Wind O&M, CLP India Pvt. Ltd.

The cumulative installed wind capacity in India reached ~39GW in March 2021, this is expected to rise to 60GW in the next few years. O&M of such a large fleet will call for innovations and upskilling on a grand scale. Outlined in this article are some of the best current ideas for adopting new technology to optimise an aging fleet.

A more complex technology than Solar, wind has more scope for digitalization and remote monitoring especially of rotating parts, generating large amounts of data and lending itself to AI. Experience has shown that most wind farms, when maintained well, will operate well beyond the design life of 20 years.

SCADA

At the heart of digitalization and the transition to AI is the use of big data and analytics that is supported by data from the SCADA. Though SCADA is an integral part of most wind farms, it requires upgrading to avoid obsolescence (that usually occurs within a decade) and to improve cyber-security. Replacement systems can offer conversion to GSM or RF based networks which will ease pressure on the rights of way problem faced in conventional OFC based networks.

Balance-of-Plant (BOP)

Drive Train

The BoP system is the poor relation of the WTG but has an equally big impact on availability and generation. Remote monitoring of the main transformers coupled with manual hotspot detection on older ACSR type conductors on transmission lines can pick up developing problems before they cause loss of production. Rectification of poles, stay-wires, cross-arms, insulators, earthing is all low-tech unglamorous activity, but operators ignore this at their peril.

Retrofitted condition monitoring devices on older drive trains makes sense when coupled with upgraded SCADA to aid the conversion to predictive maintenance. Single point grease lubrication should be making way for the new “progressive” type continuous lubrication to make over or under lubrication a thing of the past. And finally, there are hand-held ultrasound techniques which can be deployed to check the healthiness of critical bearings.

Wind Turbine Blades

Yaw and Pitch Systems

WTG blades age, wear and degrade through time with leading/trailing edge erosion, lightning strikes etc. Cleaning, inspection and repair can recover as much as 1% generation as well as avoiding more serious breakages. Rapid inspection is an ideal application for drones with blade cleaning similarly lending itself to robotic applications, while cutting downtimes.

Yaw misalignment places unnecessary stress on the main components of WTGs and so is a significant cause of wear and tear as well as reduced production. Early detection is possible using LIDAR or other diagnostic tools to compare wind direction with WTG alignment. Similarly, even minor errors in the blade pitch alignment can cause disproportionate AEP losses. The misalignment can be detected rapidly with the help of highspeed camera devices mounted on the ground.

Vortex generator strips applied to the blades in-situ at any time in the life of the machine is an excellent innovation which in the right circumstances can raise production by up to 2%.

A more complex technology than Solar, wind has more scope for digitalization and remote monitoring especially of rotating parts, generating large amounts of data and lending itself to AI. Experience has shown that most wind farms, when maintained well, will operate well beyond the design life of 20 years.

Fire Protection System (FPS)

Catastrophic fires in the wind turbines are rare but spectacular events, captured by the public and sent viral on social media.

The technical story is one of danger, long downtimes and severe loss of generation. Targeted passive FPS for power cabinets and cable terminal boxes (the most common source of fire) coupled with specialised extinguishant can limit damage and therefore downtime. Installation of thermal blankets at vulnerable locations helps to prevent spread of fire.

SUMMARY

When deployed by a skilled asset management team, these tools can assist in optimising wind asset performance and extending the life of wind turbines. The same team should be monitoring new technology to identify and adopt promising new ideas.

generation. Data analysis of wind turbine performance reports

As project margins are becoming narrower with every auction, project developers are looking for new and innovative methods and techniques for reducing O&M cost (when compared to solar PV , wind O&M cost is more than 3 times / MW basis with at par LCOE) , leading to increased profitability for prolonged wind power plant operations.

1). The industry is looking toward automation, data analytics, smart technology, and artificial intelligence (AI) for effective maintenance of wind power assets with minimal human interference.

Upcoming O&M trends are: a). Drone inspections for blades; Powerful sensor arrays in drones collect and transmit data on rotor blade conditions for expert analysis. Regular inspection of blades is necessary to diagnose and fix wear and tear due to erosion. Therefore, elimination of the human factor, reduced cost, and the huge amount of data collected on software platforms through using drones are likely to give the project developers an edge for effective monitoring and timely maintenance of the turbines for longer life span and reduced capital expenditure.

Predictive maintenance for Wind Turbine blades effective at 95% Drone, 55% rope & 35 % ground-based inspections b). Blade Maintenance Robots for monitoring and basic servicing, including cleaning and polishing of wind turbine blades. The robots utilise a vacuum pump for vertically climbing up the rotor blades. c). Automation and AI: Automation and AI helps collect data from various sources and analyse this on a software platform resulting in proper decision-making and effective functioning

and adjust the pitch angle accordingly for optimised power can also produce system-generated alerts on the health of the turbines for timely maintenance and replacement if necessary.

Shift from comprehensive OEM driven O&M contract to 3rd party ISP OR In-house operation and maintenance, post warranty period. This could help for better control on opex and plant availability / reliability especially during midlife during 10-15 yrs of plant operation and extended plant life cycle .

Variable pricing for performance / Energy based availability, then guarantee value , revenue sharing model gives incentive to O&M contractors and win-win proposition for IPPs too to optimise generation and LCOE. Shifting to Energy based resource availability from time based, optimises scheduled/ predictive maintenance during low wind season and helps to harness optimum PLF during peak windy months. MTTR/ MTBF incentives to O&M operator to perform at optimum level.

Use of Predictive Technologies to Boost Performance and Reduce Maintenance Cost : Condition monitoring systems (CMS), which enable forecasting component failure, are one of the predictive technologies that can be used to optimize the performance of the machines and also reduce the operation and maintenance costs. Sensors such as oil particle counters can extend the capabilities of diagnostic systems used for wind turbines. Main bearing damage detectors also have proven to be useful. Offline oil filtering systems increase the reliability and reduce maintenance costs of the hydraulic machines.

End of life extension : As wind sector matures growing number of turbines will reach the end of 20 yrs design life .

Many asset owners will choose life extension to delay decommissioning costs . In house O&M philosophy after 5 yrs of operation helps IIPs to have better control on cost / spares management and life extension

The need to embark on a “Modernisation Journey”, to be “Future Ready” and maintain the cutting edge for any organisation involved in O&M activities with a purpose, needs no emphasis. Only the purpose/ aim of O&M related to Wind Power needs to be re-defined. Viewing O&M activities of Wind Farms from a more revolutionary perspective, i.e., as a Production function instead of the classical concept of considering it a repair/ restorative function is essential to achieve the commitment of an organisation, focussed on its clearly defined target of “Delivering more MWh of Energy per MW of Installed Power” at a minimum cost.

Departure from Availability to Operational Efficiency is essential by adopting the following features enabling best use of emerging technologies:

⇒ Data capture, analytics with capability of monitoring and

The HWS therefore becomes the centre of focus for our “Wind Energy Converters” during which 80% of the annual generation is achieved. All preparations including major maintenance actions need to be taken well before its onset to ensure peak generation levels. This enables us to capture maximum energy from the favourable prevailing winds during this season, bringing us to the concept of “Equipment Sustainment”, implying the assurance of increased machine availability (almost 100%), not only at any point of time, but during the entire duration of the intensive period of HWS. Achieving this requires serious forethought, extensive planning and availability of resources in terms of, trained manpower, finances and the right material at the right time at the right location.

“Equipment Sustainment” in fact should aim at creating capabilities to make all WECs fully operational right through the entire HWS, to fully exploit favourable generating conditions. It is not only a critical factor in ensuring maximised generation, but a critical operational procedure that prepares & quickly recycles the WECs onto peak performance levels at all critical times, should there be an issue at any stage. The classical approach of working on availability as a measure has certain inconsistencies.

control of wind farm assets

⇒ Powerful & Dynamic O&M support System to have a positive grip on performance levels of the wind Assets

⇒ A system to drive Operational efficiency rather than timebased availability, ensuring maximum energy yields.

⇒ Reliability Management tool to ensure equipment longevity ⇒ Making use of AI, Virtual & Augmented Reality systems including Machine learning.

The management of Renewable energy assets must follow a “Systems Approach '' to be both, effective & economically most competent. Any system would have sub-systems, which may be individually independent but their performances are interdependent. Their objectives may be mutually conflicting in certain areas, like cost & reliability requirements; there needs to be an intelligent trade-off, to attain most efficient results.

The whole focus of systems approach is to appreciate the aim in totality and optimise total system effectiveness and not merely optimise each system in isolation.

The “Maintenance Engineering Organisation” of today must have a technology driven system, enabling it to analyse equipment readiness; and to understand what drives readiness, ultimately ensuring peak generation levels. Without this understanding, we would be unable to identify where the problems and opportunities are; which process improvements are paying off & where added impetus is needed. Process mapping and inter-dependent process management comprising a family of technology, techniques and formal protocols need to be created & adopted. This concept of “Sustainment” for peak operational performance is further elaborated.

Activity Based Systems Evaluation

We need to broaden our process vision & focus on our core business process of providing “Intimate Engineering Support (IES)” to execute a “equipment reset” / “equipment optimality regeneration”. While having a re-look at existing processes, to graduate to the equipment sustainment concept, one major issue that will be required to be addressed is examining failures, wind farm wise over the course of a pre-decided period of time, to examine specific WEC failure processes. Data analytics techniques must be exploited.

A Practical Approach Towards Equipment Sustainment Enhancing Reliability

With this backdrop, fully armed to meet the fundamental goals that are required to be achieved, a practical approach needs to be adopted towards physically handling the Operations & Maintenance in the field keeping our aim as elaborated above in focus. In the wind sector, we have two clearly distinguishable domains of the “High Wind Season” (HWS) & the “Low Wind Season” (LWS). The former can be compared to a “High Intensity War Engagement“ while the latter to a “Low Intensity Conflict” scenario with opportunities to reorganise & retrofit.

These domains possess equally discernible potential magnitudes of generation.

ANNUAL ISSUE 2021 | PAGE 19

In order to enhance Reliability, it is logical and imperative that necessary actions to undertake comprehensive reset maintenance, medium repairs / overhauls, recapitalisation (metrics being ‘Like New’ condition) are taken during LWS. These should be done, ensuring completeness in contents & processes. Need to establish lifed components (established specified life of critical & expensive components), rotables (those requiring re-cycling after retrofitting & overhaul) and

ensure replacements are readily available. Monitoring and logging the usage of these components, with pop-up alarms well in time to execute desired actions will be necessary.

A poorly conducted re-set is akin to complementing the breakdown failure rates & reducing reliability, adversely affecting performance levels. It also compromises on the original integrity of the system by insertion of sub-standard (or life-expired) spare parts and expendables.

Highly Trained, Fully Equipped Quick Response Teams

During HWS, it is absolutely essential that effective & efficient quick response teams are available to attend to minor issues, to ensure peak performance of all WECs. This can be achieved by re-organising the front line maintenance organisation. Broken into small teams (two or three persons), ensuring full support capability, they would operate in a manner, that they are provided “swift mobility”, efficient communication systems, and with a proper technical proficiency based on exhaustive training system, evolved with a “systems concept”. Lightly equipped with special tools & test-jigs, these teams need to be supported by inter-active electronic technical manuals on handy I-pads, coupled with the use of AI, Virtual/ Augmented Reality techniques to obtain expert advice from a remotely located systems expert.

These teams could also carry with them condition based monitoring systems using embedded diagnostics & prognostics.

To support them, (based on realistic wastages data) adequate floats & rotables are available with the team to cut out AWT to the extent possible.

These teams could be controlled by the head at Site / Regional level, who would be equipped with a real time “Operational Engineering Site Map”, which would be tracking operational parameters (like SCADA system) with total asset visibility in real time.

Since all major issues would have been attended to during LWS, the probability of needing to attend to major problems must be minimal. The effectiveness of sustainment by organising highly responsive Operational Engineering Support teams can enhance annual generation levels by more then 30%

Wind Turbine Selection—for Sustained Peak Performance It is imperative that IPPs going in for new acquisitions, must select/ identify equipment with:

⇒ An orientation towards Higher Reliability instead of being cost centric ⇒ Maintainability, a design feature. (carrying out a Maintainability Evaluation Trial would be a good idea) ⇒ Amenable to Life Cycle System Management by examining: History of Failure Rates ⇒Reliability Degradation due to ageing, weather, temperature &

humidity effects The other aspects focusing on readiness drivers are: Spare-parts support, availability & provisioning based on lead times Creation of floats/ critical retables Training & Competency building requirements With vast experience of maintaining these machines, the service operations department needs to create data mining, modelling and interactive visualization capabilities, providing critical inputs to planners for developing a “Continuous Improvement Programme”.

⇒ ⇒ ⇒

Conclusion

High level sustainment requirements need to be pragmatically evolved based on experiences of supporting the make, type & model of each Wind Turbine. A courageous sustainment plan based on “next practices”, candour and competency levels would recreate a situation guaranteeing near cent percent availability of equipment during the HWS. Right balance between cost, schedule and performance will optimize precious life cycle cost and guarantee “Delivery of more “MWh of Energy per MW of Installed Power” at a minimum cost.

“Equipment Sustainment” in fact should aim at creating capabilities to make all WECs fully operational right through the entire HWS, to fully exploit favourable generating conditions. It is not only a critical factor in ensuring maximised generation, but a critical operational procedure that prepares & quickly recycles the WECs onto peak performance levels at all critical times, should there be an issue at any stage. The classical approach of working on availability as a measure has certain inconsistencies."

"Wind Turbine O&M have taken 180 degrees turn & shifts towards the WTG Asset Management, which not only includes the regular Preventive and Breakdown Maintenances but also includes the Data Analysis & Predictive Maintenance as a regular practice. Earlier were the days when OEMs provide a simple HMI to Monitor real-time P, Q, Wind Speed and Direction, accessibility to the Fast and Event logs was a Taboo for on field operators and hence they were happy with WTG Availability as the most important KPI. Now with the introduction of Smart technologies like IoT, Drones, etc things have Continually improved and hence the performance of the WTGs.

Use of Computerized Maintenance Management System (CMMS) for records keeping of Performance, Breakdowns, Actions, with Analogue and Digital parameters. Recording Photographs and Video with audio are also important for Root Cause Analysis (RCA).

CMMS enables the Operator to analyze the Maintenance related issues through short term and long-term trends plotting.

It also empowers the Operator to Prioritize the WTGs for maintenance requirements.

With good quality records- OEMs and Component Experts (like for Generator, Blade, Rotor, Gearbox, etc) are more empowered and feels easy to find the real cause of the issues, this also empower them for further technical improvements in the products to prevent the Downtimes and improves performance.

Some of the Best Practices & Technological Innovations are as: Use of Drones for Observation and Detection of issues in WTG Blades. This not only reduce the efforts of Operators but also reduces the Accident Risks for the Operators.

Issues like cracks, dirtiness, manufacturing defects, etc are being easily catches at the right time before they have considerable impact on the Energy Production.

For inspection of Anemometer, Wind wane, Nacelle, etcdrones are becoming a Hawk Eye for the Operators.

Use of Artificial Intelligence (AI) and Machine Learning with a better approach of capturing the data points from individual WTGs and comparison among a cluster of WTGs. For AI and ML most important is the data, which is nowadays- Collected, Harmonized and Processed at Clouds for better computation and analysis.

Data Communication redundancy is also being used and alternative communication methodologies like GSM modems, Radio Frequency, etc being adopted.

Improvement in the data collection techniques and making it redundant. Now data is not only saved at sites, but in parallel at Central Servers like Clouds are being utilized for the same.

Realtime and long-term analysis of WTG Power Curve enables the Operator to exactly find out the Low Performing WTGs, even though the WTG availability is 100%.

Use of Power Plant Controllers (PPC) for WTGs have improved the WTG Power Quality, PPC becomes extremely important when we need the high-Quality Power at the Grid Level which makes the Grid more stable & Sustainable.

A high end PPC with real-time functioning for Controlling are added with features for Energy data and modelling become Energy Management System (EMS) EMS not only benefitting the Operator, Owners and Grid now, but also opening the opportunities for future too for Power Trading and Energy Exchange.

ADVANCEMENTS IN WIND TURBINE TECHNOLOGY: IMPROVING EFFICIENCY AND REDUCING COST

Shashi Barla Principal Analyst, Global Wind Supply Chain and Technology (Onshore and Offshore), WoodMackenzie

Wind auction prices around the world have declined by 50% in the past six years. The trend is no different in India, too, barring the near-term price escalation due to structural challenges. Turbine OEMs and component suppliers are working in tandem to innovate on new turbine technologies with an end objective of lowering the LCOE (Levelized Cost of Electricity) for wind farm developers /asset owners. One of the fundamental limitations of technology innovation and scale-up of components is logistics, not the technology itself. Components have grown so massive that many face technical and economic challenges in getting them to remote project sites. The industry is working on solutions that circumvent these bottlenecks.

OEMs and suppliers are accelerating innovations in modular-blades, carbon pultrusions, segmented towers, onsite-concrete tower, hybrid towers, and increased power density in gearboxes, hybrid drive trains, transitioning to medium-speed drive trains with permanent magnet generators, enhancing main bearing reliability with the large diameter tapered roller bearings.

Most global markets migrate to higher-rated turbines associated with longer rotors diminishing the regional nuances in the next five years. The global onshore average turbine rating is at 2.8MW in 2020 and expected to increase up to 4.7MW by 2025. Lower wind regimes in India and the cost sensitive nature of the market prompts the turbine growth to 3.2MW by 2025 compared to 2.2MW in 2020.

OEMs and blade suppliers like LM innovate on new materials, fibers, resins and core materials to develop slender blades with improved aerodynamics, structural designs and lower mass. The top four Western OEMs now include carbon fibre in their onshore blades, reducing

ANNUAL ISSUE 2021 | PAGE 22

weight and increasing stiffness. SGRE recently manufactured the world’s largest blade, 108m, for its SG 15.0-222 DD turbines, surpassing LM 107m blades by just one meter. Vestas launched a V236-15MW turbine with record 115.5m blades. Despite leading the onshore blade lengths race, Chinese OEMs are not likely to switch to carbon in the next three-four years, while a few peers are contemplating utilising carbon only on select 90+m offshore blades.

Gearbox Suppliers continue product innovation to increase power density through material innovation and shift from two planetary stages to three planetary stages with an additional helical stage. ZF developed a successful platform strategy with SHIFT series covering broader markets and torque requirements. Winergy leads innovation, developing HybridDrives by leveraging gearbox and generator technology know-how. Such technologies will become a preferred choice for >5.XMW WTGs. Torque density is still a key focus; gearboxes with a torque density of 200Nm /kg are now commercially available, compared to 80Nm/kg on the legacy generation 2.XMW platforms ten years ago.

The pursuit to lower LCOE has led to a frenetic pace of new product introduction (NPI) in the past five years. As an adverse consequence, the commercial life cycles of the turbines have shrunken dramatically, exerting tremendous pressure across the supply chain. Companies must innovate, invest in R&D (Research and Development) and reduce the time to market of next-generation technologies. Leading players are developing integrated product modules that can be customised for multiple wind regimes lowering the NPI and supply chain costs. Vestas and Chinese OEMs lead the transition to MS GD architectures; early adoption of SPMG technologies paves a smooth transition for Chinese OEMs. The US-China trade tussle and conducive manufacturing policies such as “Make in India” led India to emerge as a global hot spot for the wind supply chain, a clear alternative to China. Leading global turbine OEMs like Vestas, SGRE, GE and Nordex have already established or in the process of establishing India as a key global hub.

The component suppliers are also following their customers and expanding the facilities. The supply chain economies of scale advantage can be leveraged to lower the landed turbine costs for wind project developers/asset owners.

OPINION WILL INDIA ACHIEVE ITS TARGET OF WIND CAPACITY OF

60 GW BY 2022?

WHAT CORRECTIVE ACTIONS ARE REQUIRED TO EXPEDITE THE GROWTH?

Wind Installation trends 1.9 GW (2017), 1.4 GW (2018), 2.0 GW (2019) shows reflection of lacking mainly due

Deepak Khare Chief Operating Officer (Wind Business), Engie India

India, the world’s fourth-largest onshore wind market by installations ( following China – US- Germany) , is likely to fall short of its ambitious wind energy target for 2022 by up to 10 gigawatt (GW) due to various ongoing regulatory/technical challenges: Delay in signing Power sale agreement (PSA) with DISCOMs (largely due to lower module prices leading to solar tariff reduction & wind power costlier substantially) with anticipation that solar module prices will decline further .

However, Electricity demand now picking up and imposition of 40% basic custom duty on solar modules will be unlikely to fall further in the near term. Missing link of PSAs affects the entire value chain, literally impossible to secure debt financing leading to delays in financial closure.

Land acquisition delays, especially in Karnataka where longer lead time for Non-Agriculture conversion and developer permission (from state nodal agencies) for private land in Gujarat for ISTS projects.

Green corridor Grid s/s availability for ISTS allocated projects, to align with project implementation timelines.

PPA (power purchase agreement) sanctity, where re negotiation of tariff being discussed due to falling tariff trends.

On-shore wind future growth seems to majorly be driven by the expiry of the inter-state transmission (ISTS) charges waiver in 2023, as well as the trend of hybrid tenders combining wind, solar and storage technologies.

Supply chain disruptions and strict compliances during construction stages due to the COVID-19 impact would

to above regulatory & technical issues and 1.5 GW ( 2020) largely because of Covid -19 outbreak.

further compound existing challenges to implementation delays.

Limited turnkey EPC players (in past leading domestic / global OEMs provides turnkey solution ) , keeping in view of high risks associated with a) land acquisition b) securing ROW for WTG logistics movement within windfarm c) evacuation infrastructure ( 33KV and EHV ROW issues ) d) Delays in statutory permits from Ministry of defence /Airport Authority / State nodal agencies; which leads IPPs / developers to take all such potential WRAP risks and implement project under EPCM model .

With increased WTG rating, higher blade lengths technology of split blade & state highway infra will also play a major role in wind development / capacity addition. Wind Installation trends 1.9 GW (2017), 1.4 GW (2018), 2.0 GW (2019) shows reflection of lacking mainly due to above regulatory & technical issues and 1.5 GW ( 2020) largely because of Covid -19 outbreak. These above issues need to be addressed to build IPPs and investors’ confidence and increase ramp rate to meet 2022 and beyond targets. With the launch the world’s largest (30 GW) Hybrid Renewable Energy Park in Kutch district, Gujarat. More such hybrid parks are expected to be developed across India on the lines of solar parks. These hybrid parks can be installed on a plug and play model wherein the land and power evacuation facilities being provided by Wind power development agencies. Also, hybrid tenders are increasingly gaining traction wherein the minimum wind capacity is 33 percent of the contracted capacity.

PLI SCHEME FOR WIND

Amar Variawa "Sr Director – Public Affairs India and SE Asia" Vestas Wind Technology India Private Limited

On 1st Feb 2021, Hon’ble Finance minister of India Smt Nirmala Sitharaman, announced an outlay of INR 1.97 Lakh Crores (~26.60 Billion USD) for the Production -Linked Incentive (PLI) schemes for 13 key sectors. Some of these sectors are Automobiles, Telecom, Pharma, Food Products, Electronics, White Goods, Steel, High Efficiency Solar PV modules, etc.

The underline objectives of PLI scheme is To make domestic manufacturing globally competitive To incentivize break-through innovation and technologies of tomorrow To develop integrated manufacturing or manufacturing park to promote local content To create jobs and skill sets

Indian Wind Sector With more than 39 GW of installations and around 3 decades of experience, the wind sector is quite matured in the country. The sector has created more than 2 million jobs in OEMs, IPPs, Developers and 4000 MSMEs. However, the sector is going through challenging times due to consistently low commissioning volumes since the last 4 years. There are only a few OEMs active now in the country.

MSMEs and other value chain partners are moving away from the wind sector.

Why Wind Sector needs PLI On the face value, the sector has around 10 GW of manufacturing capacity with approximately 70% local content capability. So why even consider this sector for the PLI scheme. However, the realities are different. Let’s understand the rationale behind considering the wind sector for the PLI scheme in the backdrop of an ambitious target of 140 GW of wind installation by 2030.

ANNUAL ISSUE 2021 | PAGE 26

Technology and Innovation : I strongly believe that “ Today’s technology is tomorrow’s commodity ”. In the last 30 years, Indian wind turbine technology has evolved from sub-MW to 2 MW platform. In the next 10 years, it will be witnessing many breakthrough innovations and technological interventions which are suitable for Indian wind conditions. We need to design and develop India specific wind turbines in India by Indians. The Government has announced 30 GW of offshore wind by 2030. Indian offshore wind dream can’t be fulfilled with imported wind turbines. They must be manufactured in India with world-class technology and best-in-class footprints. Besides that, a whole new set of opportunities are in front of us to integrate wind power with green hydrogen and Power to X initiatives. So it makes sense to incentivize WTG OEMs and value chain partners.

Export : One of the underline objectives of Make In India initiative was to boost domestic manufacturing capabilities for domestic and export markets’ critical energy and infrastructure need. India has been emerging as a Global Manufacturing Hub for the wind sector. All major OEMs and component manufacturers are considering India in the center stage of their strategy. Needless to mention that export plays a vital role for both company and country. To create a conducive export environment for the world market, Govt should extend their support to make the export from India more competitive with respect to China.

And hence, the export activities should be incentivized.

Local Value Addition: We are in the beginning of the current decade. This is the apt time to promote setting

up of integrated plants with technologies of tomorrows, world-class quality, and competitiveness.

Sector will be witnessing the bigger wind turbines, blades, hub and nacelle. Hence, philosophy of local value addition will be essential irrespective of green field or brown field projects. Special incentives must be designed to encourage local value addition with the latest technologies and innovation. This will enhance job creation and ultimately skill development.

This will also help in curbing cheaper imports and reduce import bills.

ANNUAL ISSUE 2021 | PAGE 27

Sustainability: As per the net-zero road map published

by International Energy Agency, there will be more emphasis on scaling up the development of wind and solar globally in this decade. While this is a welcome news, it brings additional responsibility of making entire deployment more sustainable with minimum carbon footprints. Circular life cycle of wind turbine blades may help resolve the biggest challenge of 100% recyclable wind turbines. The whole narrative of climate change efforts in terms of ESG and sustainability should be incentivized by the Govt.

In nut- shell, 31% of 450 GW ambitious target of RE power installation by 2030, will be contributed by wind in various forms – onshore, nearshore, offshore, etc. Power to X and Green Hydrogen will bring a host of opportunities and challenges to deal with. Wind sector must maintain the boots on ground and eyes on the horizon. And hence, there is a strong need for the sector to be incentivized in the form of PLI scheme

WIND

THE CRITICAL LINK TO INDIA’S ENERGY TRANSITION

I

ndia’s electricity demand is projected to grow at 9.9% yearly towards 2025 driven by its sheer size and economic growth. The demand dipped temporarily in 2020 due to Covid-19 induced lockdowns, however, recouped shortly and long-term projections remain strong.

Renewable energy will be the central axis to meet this demand and wind will continue to play a critical role in India’s energy transition story. As of March 2021, the Indian wind market stands at 39.2 GW of installations. COVID-19 impact was much more severe than anticipated in 2020. The market was expected to install 3.3 GW in 2020 but only 1.1 GW was realised. Out of 3.3 GW, nearly 0.8 to 1 GW of capacity scheduled for commissioning slipped into 2021 and around 1.1 GW of capacity was backed out by developers or not granted COD extensions.

Towards 2025, the Indian wind market is expected to install nearly 20.2 GW. However, external shocks will continue to impact the market including the COVID-19 crisis, supply chain shocks related to cost escalation as well as transmission evacuation delay related shocks. If these continue in the market, we are expected to see a conservative scenario of installations around 14.8 GW. On the other hand, if these issues are resolved actively by 2025, then we might even see the market overperforming itself and moving towards an ambitious scenario of 24.4 GW of installations in the next five years.

ANNUAL ISSUE 2021 | PAGE 28

This forecast is driven by a combination of pipeline and new tender awards where the market is expected to install 10.3 GW from the current pipeline and 10 GW from new tenders towards 2025.

In terms of the current pipeline, India has awarded around 16.8 GW of wind capacity through wind and hybrid tenders. Around 10.3 GW of this pipeline is currently active and is expected to remain resilient in our base case scenario. However, if the external shocks actualise and continue to impact the volumes, then only 7 GW of this pipeline will get materialised in the conservative scenario.

In addition to this current pipeline, another 10 GW of new tenders are expected to be awarded in the wind as well as hybrid auctions in the base case scenario by 2025, and around 7 GW of such volumes will get awarded in the conservative scenario. The new volume creation in the market originates from non-solar RPOs (Renewable Purchase Obligations). Currently, we have RPO targets of around 10.25% in the non-solar category which is expected to go to 10.5% towards FY 2022. However, the trajectory post FY2022, remains uncertain, demand for new non-solar supply can vary between 17.7 GW to 29.7 GW, depending on how aggressive are states on the RPO targets.

In addition to DISCOM linked non-solar RPOs as the core driver of the market, a new untapped market remains a potential area for wind installations which is the corporate PPA (Power Purchase Agreements) market. To date, the Indian corporate PPA market is small and has nearly 9 GW of wind installed capacity under the C&I sales category. As the initial load requirements of corporates go beyond what can be met through solar, integration of wind in the C&I (Commercial and Industrial) portfolio will be a logical choice to pick up the additional demand, especially as hybrid wind-solar projects.

DEEP DIVE INTO INDIA’S OFFSHORE WIND POTENTIAL

I

ndia is aiming at ensuring energy security by the means of the country's Low Carbon Emission Pathways. Renewables must play a larger role in diversifying the country's energy mix, not only to minimize the consequences of global warming but

also to reduce pollution and provide new economic opportunities. In the discussion on renewable solutions, offshore wind energy is gaining traction. With a 7600kilometre coastline surrounded on three sides by water, India has a high chance of harnessing offshore wind energy. The article provides you with all the necessary insights about India and offshore wind energy.

THE CONCEPT AND ITS WORKING With over 30 gigawatts (GW) of installed capacity, India has a lot of expertise with onshore wind turbines. The country has also agreed to use offshore wind energy as part of its efforts to combat climate change. Offshore wind energy is a clean and renewable energy source generated by harnessing and harvesting the wind's force and power on the open seas, where it reaches a higher and more consistent speed than on land due to the lack of impediments and barriers. Megastructures seated on the seabed that are equipped with the latest technical innovations are installed to make the most of this resource. Offshore wind, as an inexpensive, scalable, and sustainable indigenous resource has the potential to help India satisfy its electricity demand and achieve its larger strategic energy goals.

PRESENT SCENARIO According to the Ministry of New and Renewable Energy (MNRE), India has an offshore wind energy potential of over 70 GW, which is primarily distributed along with parts of the Gujarat and Tamil Nadu coasts. Based on early analysis of satellite data and data from other sources, eight offshore zones have been identified in Gujarat and Tamil Nadu, respectively, as potential offshore wind generating zones. For the first 1 GW project in Gujarat, the MNRE is presently seeking cost-effective solutions from stakeholders. Meanwhile, government officials are looking into the forms of offshore wind power purchase agreements (PPAs) and auction designs.

GOVERNMENT INITIATIVES The Indian government notified the National Offshore Wind Energy Policy back in 2015. According to the policy, the Ministry of New and Renewable Energy will serve as the nodal ministry for the development of offshore wind energy in India, collaborating closely with other government agencies on the development and use of maritime space within the country's Exclusive Economic Zone (EEZ), and will be responsible for overall monitoring of offshore wind energy development. With many other government programmes in force, the future of the Indian energy mix seems to be more dependent on renewables.

BENEFITS OF OFFSHORE WIND ENERGY This sort of renewable energy has various advantages, including the fact that it is infinite, as wind is inexhaustible and does not contaminate the environment. This is particularly because it is a source that produces low carbon emissions which make up to be the main ingredient for global warming.

Moreover, the wind blows more on the water than on land and so it can produce twice as much electricity on the water than on land. These plants have the least visual impact and produce less noise, allowing for far higher installed power than on land, perhaps reaching hundreds of megawatts.

Offshore wind turbines can now obtain significantly bigger unit capacities and sizes than onshore wind turbines due to the ease of maritime transport, which has few restrictions on cargo and dimensions compared to land transportation.

FUTURE OUTLOOK The Ministry of New and Renewable Energy (MNRE) recently declared that it will set medium and long-term offshore wind energy targets of 5 GW by 2022 and 30 GW by 2030. Constant and continuous research and studies have been taking place to recognize and identify high spots in the Indian subcontinent to make the most use of the state's geographical diversification. Preliminary investigations show that both the southern tip of the Indian peninsula and the west coast have good wind potential for off-shore wind generation.

Conclusion From environmental to transportation, offshore wind energy provides diversified benefits. With notable benefits and extraordinary efforts, offshore wind energy can be considered to be the future solution to India’s energy demands. With the growing demands, India is offset to face all the potential challenges that offshore wind energy might bring in with regards to technical developments or other innovations.

ROLE OF WIND ENERGY IN TACKLING CLIMATE CHANGE

T

he power industry is responsible for over 40% of worldwide Carbon DiOxide (CO2) emissions, and it is evident that we will not be able to defeat climate change without a significant transformation in how we produce and consume

electricity. Due to huge growth in global power consumption, renewable energy technologies must be promptly implemented to

supply

emissions-free

renewable

electricity

to

both

developed and developing countries alike.

What Is It? Renewable energy is one of the most powerful instruments we have in the fight against climate change, and it has every incentive to succeed. Over the last decade, wind energy has seen tremendous growth and cost reductions, with no signs of slowing down. Wind energy is becoming increasingly competitive with fossil fuels across the country as prices fall significantly. New renewable energy sources and wind energy instruments are already cheaper in certain regions than running ageing, inefficient, and filthy fossil fuel or nuclear power facilities. Wind energy is a feasible alternative to burning harmful fossil fuels because it does not produce CO2 or other pollutants into the atmosphere. A wind turbine offsets all emissions from its construction within three to six months of operation, allowing it to operate essentially carbon-free for the rest of its 20-year lifespan. This makes this an outstanding solution for combating climate change.

How Will It Help?

Wind power produces no greenhouse gases and has an excellent energy balance. The calculations for how much CO2 wind energy may save are based on a carbon intensity assumption for the worldwide electricity industry, that is the normal amount of CO2 emitted by producing one kWh of power. In over 70 nations throughout the world, over 1,40,000 wind turbines are already generating electricity. Many turbines work in extreme weather conditions, in deserts, in snow, at great elevations, and, of course, at sea in various parts of the world like Europe, Africa, Asia, North and Latin America, and Australia. Wind energy may be employed on a huge scale almost anywhere, and the overall wind resource is enough to power the entire world multiple times over. Wind energy has numerous advantages, which is why it is one of the world's fastest-growing energy sources. The global wind energy industry is capable of producing electricity at such a pace which helps in cutting down carbon emissions to a large extent (GWEC).

ANNUAL ISSUE 2021 | PAGE 32

Challenges Some challenges are also accompanied by a set of significant benefits. One of the biggest challenges that experts spotted was regarding the behaviour of the wind. At its most basic level, winds are caused by an unequal distribution of solar energy throughout the Earth's surface, which results in distinct atmospheric pressure zones. The wind then moves from highpressure areas to low-pressure areas. Installers of wind turbines strive to locate them in areas where the flow is particularly strong. The wind is perceived to be unreliable and unexpected as there are days when the wind strongly blows and there are some days when the wind is equal to non-existent making it difficult to power turbines and generate electricity. The variability and inconsistency of the wind speed make the entire process reckless and unpredictable.

Solutions To fully utilise the wind energy, new, specialized wind turbines are being made which would work better at producing electricity at fluctuating wind speeds. The above-mentioned problem demands a solution that focuses on the development of efficient turbine models. These turbines would be supplemented with bigger rotors, higher towers, and lighter yet powerful blades.

Once these changes are incorporated, the resulting grid is more stable and effective. With this, the fluctuations in the wind speed do not cause changes in the patterns of producing electricity.

Different countries are trying to link storage or various hydroelectric sources for power generation to reduce dependability and improve efficiency.

SOME CHALLENGES ARE ALSO ACCOMPANIED BY A SET OF SIGNIFICANT BENEFITS. ONE OF THE BIGGEST CHALLENGES THAT EXPERTS SPOTTED WAS REGARDING THE BEHAVIOUR OF THE WIND.

Future Wind power is quickly expanding in almost every corner of the world, with annual growth rates ranging from 10% to 40%. The world has recognised the benefits brought in by wind energy and for the same, different countries and governments are implementing multiple strategies that work best for their states.

There are a variety of grid design methods and techniques that will aid in the transition to higher and greater levels of renewable energy as we move forward. Wind energy is the only power production source capable of decreasing CO2 emissions significantly in the critical years leading up to 2020. The future of wind energy is bright and by 2030, wind could potentially generate more than 2,000 gigawatts (GW) of new capacity (ClimateChange).

Conclusion The article addresses the different aspects of climate change and the relief that wind energy can bring to it. Climate change is real and it demands serious repair! Wind energy is already assisting in the fight against climate change. And so, it is now time for us to put our foot down on the gas pedal and accelerate the process.

UNDERSTANDING INDIA’S WIND-SOLAR HYBRID POWER SYSTEM

R

enewable energy is on everyone's mind when it comes to electricity generation, not just in India but around the world. This is mostly because it provides us with the best opportunity to combat global endemics like climate change. India, as a

peninsula with a tropical climate, has an abundance of renewable resources that, if fully utilized, can drastically lower the country's carbon footprint.

Hybrid System Basics Wind-solar hybrid systems use a mixture of renewable energy sources, such as wind and solar, to generate electricity. Solar panels and small wind turbine generators are used to generate electricity in this setup. Because wind and sun energy complement each other, the system can create electricity virtually all year round. Wind aero generator and tower, solar photovoltaic panels, batteries, cables, charge controller, and inverter are the major components of the Wind-Solar Hybrid System. The Wind-Solar Hybrid System creates electricity that may be used to charge batteries and run AC appliances via an inverter. The wind aero-generator is mounted on a tower that is at least 18 meters above ground level. The aero-generator generates greater power because of its height, which allows it to catch the wind at a faster speed (MEDA).

ANNUAL ISSUE 2021 | PAGE 34

Advantages CONTINUOUS POWER SUPPLY The batteries connected to the hybrid solar systems store the energy and hence they supply power continuously and without interruption. When there is a power outage, the batteries act as an inverter to provide backup power. This is also true when there is no sun and when no energy is created in the evenings or at night; batteries provide a backup and life continues as usual.

LOAD MANAGEMENT In contrast to typical generators, which supply high power as soon as they are turned on, most hybrid solar power systems control load as needed. A hybrid solar system might feature technology that changes the energy supply according to the devices it is linked to, whether it is a high-power air conditioner or a low-power fan.

UTMOST UTILIZATION OF RENEWABLES There is no waste of the excess energy created on bright sunny days because the batteries are connected to the system to store the energy. As a result, these systems make the best use of renewable energy, storing energy on good days and utilizing the stored power on bad days. This system maintains the equilibrium.

HIGH EFFICIENCY Traditional generators lose fuel under certain conditions, whereas hybrid solar energy systems function more efficiently.

Hybrid solar systems can operate in a variety of weather conditions without wasting fuel hence making the system more effective and efficient.

LOW MAINTENANCE COST In comparison to standard diesel-fueled generators, hybrid solar energy systems have a low maintenance cost. They do not use any gasoline and do not need to be serviced very often.

Disadvantages

LESS BATTERY LIFE As the system's batteries are frequently exposed to natural elements such as heat and moisture, they tend to have a shorter lifespan.

HIGH INSTALLATION COSTS Although the maintenance costs are low, the initial investment in a hybrid solar energy system is more than that of a solar energy system.

COMPLICATED CONTROLLING PROCESS The systems necessitate some understanding due to the various sorts of energy sources used. The operation of many energy sources, as well as their interaction and coordination, must be controlled, which can be difficult.

LIMITED INSTRUMENTS CONNECTED The number of devices that can be connected to a hybrid solar energy system is limited, and it varies by system.

Indian Dynamics India has set a goal of generating 175 Gigawatts (GW) of installed renewable energy capacity as part of its contribution to the Paris Climate Agreement, with 100 GW coming from solar and 60 GW from wind. However, most stand-alone solar or wind generating plants face some intrinsic problems that limit their production. In 2018, the Ministry of New and Renewable Energy (MNRE) released a solar-wind hybrid policy, which lays out a framework for promoting grid-connected hybrid energy through configurations that make the best use of land and transmission infrastructure while also managing renewable resource variability to some extent.

Looking at the many benefits brought in by the wind solar hybrid system, the Indian government is also finding various policies to aid the development of these projects. Various government policies and programs will stimulate the development of hybrid power projects. Hybrid system developers can also take advantage of all of the tax and financial advantages available for standalone wind and solar generating projects. The government will also contribute to technological breakthroughs in the field of wind-solar power generation systems, as well as the establishment of hybrid system standards (EconomicTimes).

Conclusion The one answer for the fulfilment of all renewable goals is the adaptation of wind-solar hybrid power systems. The amalgamation of the two energy sources brings out a cumulative advantage over the independent usage of each source. Despite the existing policy frameworks, India's policy and regulatory environment must improve to fully realize the potential of hybrid energy.
