EDITORâ&#x20AC;&#x2122;S NOTE Urgent need to scale Up grid infrastructure in India to keep up with renewable surge

he Government of India is encouraging investments at the transmission and distribution level to boost access to reliable and continuous power supply through various schemes. However, it has been observed that numerous completed large-scale renewable projects were unable to be commissioned due to delays in grid infrastructure and evacuation issues. Thus, there is an urgent need for huge investments in the T&D sector specially to keep pace with sudden surge in planned renewable capacity as many in the industry wonder if Indiaâ&#x20AC;&#x2122;s transmission infrastructure is equipped to handle this influx of intermittent sources of power generation. Though, to cope with increasing renewable energy addition, India is developing the Green Energy Corridor (GEC), an interstate transmission network that would connect renewable energy rich states to states lacking in renewable energy generation potential. However, the question now is whether the countryâ&#x20AC;&#x2122;s ISTS is resilient enough to handle a surge in solar and wind generation- where various reports says that the progress so far at ground level is moving at a sluggish pace. This is quite evident as there have been instances where state electricity regulatory commissions in the recent past, have come out with orders and notices asking their distribution companies (DISCOMs) not to enter into new Power Purchase Agreements (PPAs) with solar (in rare cases) and wind project developers due to the unavailability of the required grid infrastructure. In the last few years, while renewable energy generation has exploded with a CAGR of about 22 per cent and continues to grow at the same or even greater vigour, the transmission infrastructure has not been able to keep pace and has rather lagged significantly behind. While the investment grew well in the early part of the current decade in interstate transmission, the creation of new transmission schemes have since slowed down considerably year-after-year. Currently, planning for transmission is done more as a reaction which gets triggered when the generators request for the evacuation infrastructure. The main constraint in India is not investment for renewables, but the strengthening of grids because to take a large share of renewables into the grid effectively, India needs a robust transmission infrastructure. For this, transmission planning needs to be proactive and enable plug and play connectivity in the power value chain, thus de-risking larger investments in renewable power generation......

Tamil Nadu solar policy aims to achieve 9,000 MW by 2023 The Tamil Nadu government has announced its Solar Energy Policy 2019 with the objective of achieving an installed capacity of 9,000 MW by 2023. The policy hopes to create a framework that will help accelerate development of solar installations in the State, promoting both utility category and consumer category solar energy generation through various enabling mechanisms.

According to media reports, Essel Infraprojects is in the final stages of discussions to sell its solar energy portfolio to private equity investor Actis, according to sources. The sale of the portfolio, totaling 685 MW of installed and underconstruction projects, could fetch the company about INR 4,5005,000 crore. In October 2018, Essel had announced the sale of four transmission line businesses to Edelweiss-backed Sekura Energy for an enterprise value value of Rs 6,000 crore.

About 40 per cent of the target (9,000 MW) will be earmarked for consumer category solar energy systems, said the policy document. The State government will also promote the manufacture of solar power components including cells, inverters, batteries etc.

Andhra Pradesh asks power discoms not to back out of Green PPA The Andhra Pradesh government has directed state-run power distribution companies to honour contracts signed with renewable energy developers, offering relief to generators at a time when several clean energy buyers are backing out of agreements and seeking lower tariffs. Andhra Pradesh, one of the leading states in using renewable energy, has more than 7,000 MW of solar and wind projects and aims to take it to 18,000 MW by 2021-22. Earlier this year, state utilities of Andhra Pradesh had moved a petition before the Andhra Pradesh Electricity Regulatory Commission (APERC) seeking consent for revisiting PPAs already signed with wind developers. They wanted to truncate the length of the already signed PPAs to five years from 25.

Post execution of this project, various wind farm developers will be able to transmit the power generated in Gujarat to Green Energy Power Transmission Corridor, GE T&D said in a statement.

An exercise by the Central Electricity Regulatory Commission (CERC) showed that the mechanism could have last year resulted in savings of nearly INR 6,000 crore to distribution companies of five states. If implemented, pan-India the savings are expected to be higher. CERC chairperson P K Pujari said the commission has issued suo motu order for pilot run of the scheme by letting the grid operator POSOCO pool electricity from all projects for which tariffs are regulated. The pilot run will start from April for six months after the required software upgradation.

All the 1.5 crore consumers in Bihar will be provided smart prepaid electricity meters in the next two years. Chief minister Nitish Kumar approved ‘in-principle’ the state energy department’s plan at a meeting.

The approach, however, is not without challenges. While adequate transmission capacity is an enabler, it may face resistance from some states and costlier plants. Association of Power Producers director general Ashok Khurana said the operational and settlement issues have to be looked into for implementation.

State energy department’s principal secretary Pratyaya Amrit made a detailed presentation before the CM and energy minister Bijendra Prasad Yadav about his department’s plan to shift all the 1.5 crore power connections to smart prepaid meters in the next three years. But the CM, while praising the

Pointing out at some of the major challenges faced by thermal power projects, the study says that Non-availability of regular fuel supply arrangements, lack of Power Purchase Agreements (PPAs), inability of promoters to invest equity and working capital, and regulatory and contractual issues are plaguing the sector. Another report says that there is economic merit in closing down such power plants to meet the Paris goals. However, it will be challenging in short to medium-terms for India for its energy security concerns and national developmental targets, being a coal dependent economy. In addition, any coal phase down in India also has to consider the socio-economic-political implications on over 15 million workforce and their families.

Positive Development: An empowered committee was formed after power producers challenged the Reserve Bank of Indiaâ&#x20AC;&#x2122;s February 2018 circular for stricter bad loan recognition timeline - to find out possible measures for the revival of the sector. The empowered committee headed by cabinet secretary PK Sinha suggested policy measures to revive stressed power plants with improved coal availability, for plants selling electricity in the spot market and forceful measures to ensure timely payments from state utilities with the help of banks. It also recommended that power plants that terminate power pacts with defaulting discoms be allowed to use the coal supply for electricity supply through short-term power purchase agreements (PPAs) or power exchange for a maximum of two years. The committee has also asked the power ministry to consider a scheme enabling NTPC to aggregate power through a bidding process from stressed power plants and offer the same to discoms till its own plants are commissioned. Reserving 60 per cent of coal spot auctions for power plants, change in coal allocation policy to offer future incremental coal without auction to PPA holders and offering more coal to efficient plants have also been suggested. The government approved suggestions of a group of ministers including fresh coal supply and easier power sale norms to revive stressed power plants. The Cabinet Committee on Economic Affairs decided to go ahead with the recommendations approved by the group, originally suggested by a high-level empowered committee, RK Singh, minister of state for power, said in a press conference.

SPECIAL ARTICLE

Suggested Revival Plans According a list provided by the Finance Ministry in 2017 there were around 34 stressed power plants in the country with a total capacity of 40,130 MW and INR 1.8 lakh crore worth of loans. As 11 of these plants with total capacity of 11,000 MW have been resolved and the government shall be working on revival plans of remaining as per below given suggestions from the committee: The government will provide coal linkage for three months to a year to independent power producers that can generate electricity and sell it under short-term power purchase agreements. This will help the thermal power plants that have fuel-supply agreements or letters of assurance but donâ&#x20AC;&#x2122;t have medium- or long-term pacts to sell power. Further to create demand for power generated by stressed units. The committee recommended that NTPC which has pact with Discoms to sell power for capacity yet to be commissioned should act as an aggregator to buy electricity through transparent bidding from stressed power plants

and offer it to Discoms till its own plants or units are commissioned. Meanwhile, to ensure timely payment to power producers, the ministry of power may engage with the regulators to ensure that late payment surcharge is mandatorily paid in the event of delay in payment by discoms. Also a generator will now be able to terminate the agreement in case of default in payment by the discom and use coal linkage for short-term pacts for up to two years or another buyer of power under a medium- or long-term agreement is found before that. On the other hand, to ensure smooth supply of fuel certain measures have been taken like carry-forward of coal supply. Thus, shortfall caused because of the ministries of coal or railways will not lapse and can be carried over to up to a maximum of three months. Also, 50 per cent of E-Auction Quota has been reserved for power sector. In addition, to encourage efficient plants - the CEA will now prescribe an upper ceiling for annual contracted quantity per MW based on efficiency and irrespective of the capacity and actual consumption in order to ensure better use of the scarce resource.

www.powerinsight.vision-media.co.in

Summing Up In order to ensure that the plant remains operational even during time of stress it is recommended that Discoms, Coal India Ltd., Power Grid Corporation of India Ltd., the Ministry of Environment and Forests, and appropriate state governments may be advised not to cancel power-purchase and fuelsupply agreements, transmission connectivity and environmental approvals, including for water, even if the project is referred to the insolvency court or is acquired by another entity. The power industry feels that recommendations are really innovative specially allowing coal linkage for short-term contracts or bill discounting mechanism. However, private power companies are of view that the government should also have specified timelines to ensure expeditious implementation. In addition, the preferential treatment to state-owned utilities for allocation of power purchase contracts, coal blocks and coal supplies is one of the major reasons for severe stress amongst independent power producers and this irregularity should be removed. . n

Mounting Structures Market Overview

A market insight of the mounting structure industry while looking into key design consideration to overcome challenges that could help keep pace with growing solar power sector in India...

February - March 2019

ith positive growth trends seen in the Indian solar power industry over the past two years investor confidence in the segment has increased over time. This has help in greater capacity additions and positive growth reflection across associated markets - such as mounting structures. Solar mounting or â&#x20AC;&#x153;rackingâ&#x20AC;?, is at the foundation of every solar system. Having the right kind of racking can make or break an installation, as this determines the stability of the overall system. Mounting structures provide all the essential elements to drive solar power generation. They help tilt the panels at a specific angle, ensuring maximum irradiation per unit area. Over the years, mounting structures have found applications beyond the traditional groundmounted solar power plants and are now used at rooftops, carports and other sites

irrespective of the surface.

Market Overview: Two specific types of module mounting structures used in ground mount installations can be categorised by the tilt of the panels. The Fixed Tilt structures are designed at a year-round optimum tilt, as the tilt of the modules cannot be changed once the structures and modules are installed. And are used for solar panels typically facing the south direction, On the other hand, the seasonal tilt structure allows the south-facing panels to be adjusted seasonally. These structures have holes drilled into the bow of the base supporting structure that can be used to manually vary the tilt of the modules. The tilt of the modules can be varied from season to season, with changes in arc of the sun path across the sky. In most cases, the tilt of the modules is varied

www.powerinsight.vision-media.co.in

MARKET REVIEW with the season changes of summer and winter. Developers are also increasingly deploying solar tracker technology, where modules are mounted facing east-west and the tracker follows the sunâ&#x20AC;&#x2122;s path to maximise generation. This automates the manual process of physically changing the tilting the modules to the optimum angles. Different types of module mounting structures may be used depending upon the design of the plant, and the cost constraints involved. These structures are composed of a mix of HDG and pre-galvanised steel, or galvalume. The majority of the projects are based on these technologies.

Designing Precautions Module Mounting Structures play a critical role in setting up a durable, long-lasting and efficient solar power plant. With module design changing with rapid technological advancement along with increasing capacities of solar modules, weights and dimensions of the modules must also be examined carefully from design to design as they have a critical impact on the structural integrity of the installation. The first thing that should be examined before the setting up of module mounting structures, for a ground mount solar plant, is the foundation of these structures. A strong foundation is the key to a stable mounting structure. Further, in order to derive highly efficient designs, software tools may be employed, wherein local standards are used for reference. The most common inputs used are - Location (Latitude and Longitude); Structure Tilt: This tilt is dependent on the location of installation. The other important aspect to consider is the type of structural material. The material must allow for the structure to be sturdy so as to withstand the load of the module and the wind load. With these inputs, the optimized structure design and reactions for the foundation design are obtained. Thus, the overall technical soundness

of the plant can reach high levels of operation only when the Module Mounting structures are designed and constructed with great care, and with close attention to detail. Partnering with the top solar companies in India is vital here!

The Challenges The competitive bidding process has certainly compelled developers to adopt cost-effective technology solutions. Keeping up with the market, the benchmark costs of mounting structures have also been decreasing in line with other capital costs. Thus, the market has been flooded with mounting structure designs that are costcompetitive and easy to install in recent years, but are not strong enough to support the panels throughout the project life cycle. Further, customisation of mounting structures as per the project requirements and site conditions, adds to the costs. On the other hand, the cost of raw material such as steel and aluminium has also been fluctuating, affecting the mounting structures market. In addition, manufacturing issues and an influx of low-grade raw material from China are leading to quality issues across the industry. Certainly, the research and development in the raw material industry has not been able to

www.powerinsight.vision-media.co.in

sync with the rapid pace of developments in the solar power market.

Conclusion: With increasing solar power installations in India, the market of mounting structures is expected to grow significantly in the near future. Steel-based structures are expected to dominate the market unless galvalume or other polymer-based materials become costcompetitive. To produce mounting structures, 40-60 tonne of steel is required for 1 MW of solar power capacity. Over the next five years about 85 GW of solar power capacity has been planned. Thus, about 4.25 million tonnes of steel will be needed to realise the governmentâ&#x20AC;&#x2122;s solar target.According to various reports - the steel market for mounting structures could be worth Rs 25.5 billion over the next five years, if the country meets its 100 GW solar power target. However, as steel prices are expected to increase due to high demand from the automotive sector. Also, the industry needs to invest in research and development to bring down the cost of mounting structures in line with the module prices and other capital costs.n

ndia’s solemnity towards strengthening the country’s transmission network has resulted in registering a significant growth in the segment, over the past few years. The government, on its part has also been putting in substantial efforts for strengthening of the power transmission infrastructure in the country through supportive policies and required investments. However, there is still needs for some extra efforts and a makeover of existing power transmission segment to support the growing load and increasing share of renewable generation in the country’s energy mix, while simultaneously dealing with the constant cases of congestion witnessed in the transmission lines.

Segment Overview: Indian transmission sector has seen a robust growth in the last 5 years. Between 2012-13 and 2017-18, the country has seen a significant growth in its transmission network – registering a compound annual growth rate of over 7.3 per cent in transmission lines length and 11.8 per cent growth in alternating current (AC) substation capacity. As of January 2019, the total transmission line length stood at 407,291 ckt. km (220 kV and above), AC substation capacity at 855,903 MVA, and high voltage direct current (HVDC) substation capacity at 22,500 MW.

www.powerinsight.vision-media.co.in

Cover FOCUS substation capacity stood at 7.2 per cent and 3.8 per cent respectively. However, the role of the private sector in transmission and distribution sector is still limited due to licensing and legacy, among other issues. Private transmission companies have time and again raised concerns regarding the lack of a level-playing field in the segment.

Market Opportunities

The total capacity addition of transmission lines (220 kV and above) during the current FY 2018-19 up to January 2019 stood at 16,321.35 ckt. km (220 kV and above) against the targeted programme of 18,965 ckt km for the period. While on the other hand, AC substation capacity of 51,445 MVA was added against the targeted programme of 53,935 MVA during the same period. The interregional transmission capacity has also grown significantly over the years. It stood at over 86 GW as of March 2018. PGCIL added 11,400 MW of interregional power transfer capacity in 2017-18, which further boosted

the exchange of power across regions. By 2021-22, the capacity is proposed to be increased to 118 GW. The sector has also made significant strides in deployment of Extra High Voltage (EHV transmission lines, which is crucial to achieving the stated reduction in Aggregate Transmission & Commercial (AT&C) losses. Power Grid Corporation of India Limited (PGCIL) continues to dominate the country’s transmission segment with a line length of around 156,001 ckt. km and a transmission capacity of 339,536 MVA as of January 2019.

The transmission network infrastructure is expected to undergo significant expansion in the coming years. Considering the capacity addition from the government’s power for all mission and the 175 Gw renewable integration target, India currently needs about US$ 50 billion to US$80 billion investment in the transmission sector for the next five years alone. Indicating significant growth in the power transmission sector, the Central Electricity Authority (CEA) has estimated an investment of Rs 2.6 lakh Crore till 2022. Of this about Rs 1.6 lakh Crore would come from states and the other Rs 1 lakh Crore from Power Grid Corporation of India.

Since the renewable projects have a low gestation period - one of the biggest challenge is going to be the technology; how do we build these transmission assets in half the time than they are traditionally being built. needs to be developed. High capacity green energy corridors are under implementation, which will facilitate the interconnection of large-scale renewables into the national grid. In addition, transmission schemes for 7,200 MW of ultra mega solar power parks are also under implementation in various states as part of the second phase of the green energy corridors scheme. The government has introduced policy reforms to boost private participation that has activated a fresh thrust for buying and sales of transmission assets. The companies having core business in EPC or power generation and won electric transmission projects are now ready to monetise such assets to follow new projects. Investment firms have also revealed interest and adding to this, there are some companies, with core business in renewable, now eying T&D assets. With a huge buyer interest from transmission companies and yield-based investment firms, industry experts say it may be a good time for T&D sector.

Challenges & Issues Currently, planning for transmission is done more as a reaction which gets triggered when the generators request for the evacuation infrastructure. However, due to the dispersed growth of power demand in India and the unprecedented growth of renewables, an integrated system planning is required and not the earlier generation evacuation system planning. Transmission planning needs to be proactive and enable plug and play connectivity in the power value chain, thus de-risking larger investments in power generation. There has never been a better time to be in the transmission business

February - March 2019

As it is seen that the transmission infrastructure in the country has not been able to keep pace with the renewable energy generation that has burst up with a CAGR of about 22 per cent over the last few years and will continues to grow at the same or even greater pace. Thus, we urgently need to either improve the construction schedule to match with the commissioning of renewable assets or correct the transmission planning approach to ensure readiness of the evacuation infrastructure before generation begins. Though as seen in some of the recent projects, the use of drones and helicopter cranes in construction has reduced commissioning timelines and made execution more streamlined. Meanwhile, there are also some structural issues that need to be addressed in order to unleash an unfettered growth in this sector.

Conclusion The success of the various schemes announced by the government in the power sector depends on a better and uninterrupted supply of power in the country, which in turns requires a strong transmission network. Further, the push for green energy corridor, plans for developing energy storage market, targeting 100% electrification of rural â&#x20AC;&#x201C; remote areas and the anticipated increase in the power demand intimates the need for a stable grid and better transmission infra set up in the country.

Power Insight

In fact, to cater all this it has been estimated that there would a requirement of additional 100000 ckt. Kms of transmission lines by FY2022. Also, it is anticipated that by FY 2022 an additional power transformation capacity of 200000 MVA shall be needed at the voltage of 220 kV & above, attracting an investment to the tune of approximately USD 5 Billion. Today, there are more than Rs 80,000 crore projects under implementation and once these will start coming it will reduce the load on the overall sector. Although, with so far planning and achievements the projected developments in the power transmission sector seems quite well placed. However, encouraging more PPP into the sector shall be vital to meet the huge investment & capacity enhancement target in Indiaâ&#x20AC;&#x2122;s transmission segment. Therefore, more initiatives should be taken by the government to saddle the pace of private participation into the same. Private sector participation in transmission is an evolving concept and it needs strong regulatory, institutional frame work in place to create a level playing field to attract best managerial and capital management techniques from private sector, which in turn will lead to healthy growth of the sector and help keep pace with growth demands of the economy. Also, there are also some structural issues that need to be addressed in order to unleash an unfettered growth in this sector. First of all, transmission being an infrastructure-related sector in India, land continues to be an issue and will need governmental intervention to resolve. On the other hand, the growth story of the sector has also been impacted as we have seen many incapable players bidding aggressively in the transmission project auctions similar to solar auctions. In addition, PGCIL take over a majority of projects up for bidding given its access to low cost capital and strong experience in executing these projects. However, PGCIL has already reached its execution limit and should refrain from putting any more bids before clearing its pipeline. n

Advance HTLS Conductors

hoosing the right conductor technology is an important decision specially when high capacity corridors, renewable integration and larger transformer capacity have increased the demand for advanced conductor technologies, which is capable of allowing high temperature ratings and have low right-of-way (RoW) requirements.

In India, ACSR and AAAC are the commonly used conductors on overhead lines for transmission and distribution systems. The pure aluminium used is ductile and soft, which is why the conductor requires more care during handling and stringing. Over the past few years, the need is being felt for the usage of conductors that has increased power flow and high temperature resistance, low sag, and greater safety of the towers and foundations of existing lines. One such advancement in conductor technology is High Temperature Low Sag (HTLS) conductors.

HTLS Conductors: HTLS conductors are characterised by high temperature resistance and greater ampacity than conventional conductors. These are stranded with a combination of aluminium and alloy wires for conductivity and reinforced by core wires. Materials like - INVAR steel (iron and nickel [Fe-Ni] alloy), aluminiumzirconium alloys, annealed aluminium, high strength steel and metal

Cover FOCUS the aluminium strands can be made thermal resistant by either having fully annealed aluminium or by adding zirconium to obtain a thermal resistant aluminium alloy. The core is galvanised and is made up of iron and nickel (FeNi) with a low thermal coefficient of expansion.

ACSS conductors: Aluminium conductor steel supported (ACSS) conductors, which were widely used by American utilities, are similar to ACSR conductors, except that the external strands are aluminium annealed. The core is made up of high strength steel and carries most of the load and hence the sag is less compared to a conventional ACSR conductor under high temperature. GAP conductors: This is another

type of HTLS conductor with a core of steel and aluminium strands. A small gap is maintained between the galvanised steel core and the aluminium strands. It is strung by tensioning the steel core and hence has a lower sag as compared to an ACSR conductor.

Carbon fibre composite core conductors : This kind of HTLS conductor

and polymer matrix composites are used to make these HTLS conductors. HTLS conductors have 30 per cent more capacity than that of conventional conductors and the low sag feature results in a smaller tower requirement. The first HTLS project in India was implemented by Power Grid Corporation of India Limited (Powergrid) for the 400 kV double-circuit (D/C) (quad) Dadri-Ballabgarh transmission line at Maharani Bagh, wherein it deployed INVAR-type HTLS conductors. Powergrid is currently using HTLS conductors of various types (INVAR type, gap type, ACCC type) for uprating the existing 400/220 kV lines. It is also constructing new lines in forest and other RoWconstrained areas.

Types of HTLS INVAR : INVAR-type conductors are

similar to aluminium conductor steel reinforced (ACSR) conductors where

is fully aluminium annealed and the core is made of composite material like glass fibre and carbon. The conductor has less sag due to a low coefficient of thermal expansion. However, it requires special types of dead-end clamps and joints as well as more care while handling and stringing due to the softer aluminium strands.

Metal matrix composite core conductors : Metal matrix composite

ÂşC the thermal rating or the current carrying capacity offered by HTLS conductors is 2-2.5 times that of an ACSR conductor of the same size, without any appreciable increase in the sag. HTLS conductors also facilitate thermal uprating of the existing lines that use quadruple-bundled ACSR conductors with higher diameters. Twin bundle HTLS conductors are increasingly being used for uprating high capacity 400 kV extra high voltage (EHV) lines. This helps in increasing the capacity of power flow by 100 per cent.

Shortcoming The main drawback of HTLS conductors is that they have a high cost. In almost all cases, HTLS conductors require special stringing procedures/ requirements, fittings and spare parts, which add to their installation cost, making them two to three times more expensive than ACSR and all aluminium alloy conductors (AAAC). Further, despite their advantage of a high current carrying capacity, limitations are posed by surge impedance loading, thereby causing greater losses in long transmission lines deploying HTLS conductors. Further, despite their advantage of a high current carrying capacity, limitations are posed by surge impedance loading, thereby causing greater losses in long transmission lines deploying HTLS conductors.

Conclusion:

core conductors are similar to ACSR Conductors, but the core here is made up of a metal matrix constituting aluminium-aluminium oxide fibres. The external aluminium strands are made up of zirconium â&#x20AC;&#x201C; a thermal resistant alloy of aluminium.

With the National Smart Grid Mission in place and the ambitious target of achieving 175 GW of renewable energy by 2022, specialised conductors will be at the forefront of bringing about a transition in the transmission segment.

Key Benefits:

Further, with the rising power demand, there is a need to ensure flexibility in the electricity system. In this regard too, HTLS conductors offer an attractive option for high capacity EHV transmission lines and a viable solution for uprating/upgrading of the existing lines. n

One of the benefits of HTLS conductors is that their current carrying capacity is higher because of their high temperature operation, as compared to an ACSR conductor. For instance, at a high temperature range of 180-200

Installed renewable power generation capacity has increased at a fast pace over the past few years, posting a CAGR of 19.78 per cent between FY14â&#x20AC;&#x201C;18. As of December 2018, India ranked 5th in installed renewable energy capacity with approximately 75760.66 MW of installed renewable energy capacity.

Power Insight takes a look at the key emerging technologies in switchgears

he reliability of a power system directly depends on the efficient functioning of its equipment. Switchgear is one of the most important and critical components in an electrical system as it ensures power system protection and regulate power supply. In addition, it de-energises equipment and clears faults in the system, thereby, ensuring reliable power supply. In the wake of greater integration of variable renewable energy with the grid switchgear has become pivotal in ensuring that networks operate in a synchronous manner with minimum faults. Also as we are seeing an increasing pace of government initiatives for development of smart grid, there is need to develop different kinds of switchgear suitable for smart grid operation and that is more compact, reliable, environment friendly and requires minimum installation and commissioning time.

As modern business requirements call for upgraded switchgear that plays such a critical role in the operation of uninterruptable power supply systems most needed for a continued business operations.

Industry INSIGHT between 1 kV and 33 kV and including air-insulated switchgear (AIS), vacuum switchgear and gas-insulated switchgear (GIS); and high voltage (HV), with ratings of 66 kV and above, and including AIS and GIS. So far growth in the switchgear industry has been driven by a strong demand for low voltage and medium voltage switchgear. However, in recent past, the industry is witnessing a growth in demand for high voltage switchgear. Ultra high voltage (UHV) and smart switchgear are the other key emerging technology trends. The growing demand for greater transmission of power over long distances and with lower losses necessitates the more to UHV or EHV transmission technologies at 800 kV, 1100 kV and 1200 kV. These large UHV systems require switchgear that can meet safety, performance and reliability demands. Few other recent developments in the switchgear industry are vacuum switchgear, hybrid switchgear and intelligent/smart switchgear. Vacuum switching widely used in the medium voltage range, is also emerging as an alternative in HV applications. This trend is being driven by the fact that the vacuum switchgear is more environment friendly than SF6 switchgear. Hybrid switchgear is a combination of conventional air insulated switchgear and high voltage gas insulated switchgear. With the development of smart grid, the smart switchgear has also become popular. It is also capable to handle increasing integration of variable renewable energy into grid. Gas-insulated switchgear (GIS): Owing to an increasing focus on conserving right of way and ensuring uninterrupt-

ed power supply, power utilities are focusing on substation and switchgear technologies that require less space and have a reduced outage. Thus the usage of GIS has gained popularity over AIS in recent years. In GIS, sulphur-hexafluoride (SF6) gas is used, which reduces the distance needed between active and non-active switchgear parts, resulting in lower space requirements, making these ideal for urban areas.

February - March 2019

Although the initial cost of GIS substations is about 50 per cent higher than that of their AIS counterparts, the overall capital costs are comparable as GIS proves to be more economical, considering the land coverage, construction and maintenance costs, and better performance.

The other advantages of GIS include its compact size and encapsulated structure that makes it ideal for areas with space constraints. GIS substations require approximately 35 per cent less space than AIS substations and have lower maintenance and outage costs.

Air-insulated switchgear (AIS): The AIS uses air as the primary dielectric from phase to phase, and phase to ground insulation. With quality design, the system is viable owing to the low construction costs and low cost of switchgear. They have been in use for years before the introduction of GIS. Actually, most substations across all regions are AIS.

GIS switchgear is also suitable for use in locations with severe weather conditions (high temperature and high altitudes) and in industrial envi-

pollution, deposition of saline particles, lightning strikes and extreme weather conditions. AIS switchgear is easy to maintain as all the equipment is within view and it is easy to notice and attend to faults. However, continued monitoring and maintenance are essential to deliver reliable energy to consumers in a safe manner. On the other hand, the indoor AIS version is only used in highly polluted areas, and saline conditions, as the air quality is compromised. Hybrid switchgear (HS): Utilities are moving towards hybrid switchgear to take advantage of both AIS and GIS technologies as hybrid switchgear â&#x20AC;&#x201C; based substation is a mix of AIS and GIS technologies. In a hybrid substation, the busbars are air insulated and all other equipment such as circuit breakers, bushings, busducts, connecting elements, disconnectors, current transformers and sensors are gas insulated. The initial cost of hybrid substations is approximately 20 per cent higher

than that of AIS, and these substations require a moderate size of land. Moreover, as this switchgear can be installed speedily, we see a growing requirement today as the time to execute a project is reducing. Intelligent / Smart Switchgear: With the increasing integration of renewable energy into grid, there is a need for automatic switchgear solutions that provide better monitoring and control capabilities. To meet this demand, smart internet of things ready switchgear solutions are coming, which can connect to the internet to provide real time monitoring, predictive diagnostics and better protection against faults. These switchgears are embedded with intelligent electronic devices and are pre-programmed for the remote monitoring and communication of key electrical parameters like current, voltage, faults etc. In smart grid operation, automated switchgear operation is preferred over conventional operation. In conventional substations, all signals, controls and interlocks are hardwired and

These switchgear, equipped with advanced software solutions that protect systems from potential cyber threats, thereby, strengthening system security. In addition, digital substations and switchgears possess backward compatibility, which enables the smooth integration of new communication technology with the utilities existing systems. Moreover, being equipped with real time monitoring of data, it reduces outage time and increase reliability of the system. With the pace of government initiatives for development of smart grid, there is need to develop different kinds of switchgear suitable for smart grid operation and that is more compact, reliable, environment friendly and requires minimum installation and commissioning time. Moreover, with increasing integration of renewable energy, utilities would be required to increase the deployment of intelligent switchgear or to undertake modifications to transform the existing switchgear modules into smart switchgear. To sum up, the switchgear industry in India is today, technologically mature and well equipped to cater to the oncoming demands and requirements of the next generation infrastructure.n

he global as well as the Indian solar market is set to grow rapidly in the coming years mainly on account of significant cost reductions in the segment. However, now the price pressure is one of the biggest challenges faced by the industry.

With the price of solar power in India falling developers are exploring means to maximise their returns which is putting immense pressure on module manufacturers and BoS suppliers. The toughest task for a developer starts once the tariff is sealed and that is to achieve the target cost. As module prices have seen a continuous decline in the past few years - the price pressure has shifted to BoS component suppliers. Since, BoS involves a number of small components and has an important role and impact on overall plant efficiency. It is essential that while achieving the target, the quality of components is not compromised. At present, the main focus is on cost, but it is important to realise that cost and quality go hand in hand. Thus

Special FEATURE installation, and interconnection. These costs vary considerably across regions, technologies and market segments, and are significantly affected by local conditions and the regulatory environment. Apart from regional tariffs, factors affecting price variations include currency depreciation, off-the-mark downstream demand, varying customer acquisition and labour costs, and increasingly competitive pricing behaviour. In terms of market segments, residential solar systems have higher BoS costs than large commercial installations. The costs are even higher for complicated arrangements such as canal-top and floating PV systems. Meanwhile, BoS costs for utilityscale systems are much lower due to economies of scale. Over the last 10 years, module prices have plummeted, and inverter prices are following suit, though not as dramatically. The net result of this material drop is a higher impact of the BOS. Ironically, the Balance of System costs which were around 40% of the system cost some 10 years back are now, around 70% of total PV system costs. The BOS portion has become a vast majority of the system cost. To compound the problem, system cost decrease has caused smaller profits and forced the overhead to become a bigger portion of the total PV system cost.

there has to be a balance between the cost, quality and reliability of the BoS component, especially considering the fact that these projects have a lifespan of 25 years.

majority of maintenance requirements. Essentially it is through the balance-of-system components that help to control cost, increase efficiency, and modernize solar PV systems.

Segment Overview:

BoS Cost & Trends:

A Solar PV Balance-of-System or BOS refers to the components and equipment - other than the modules - that move DC energy produced by solar panels through the conversion system which in turn produces AC electricity. In addition to inverters and racking, this includes the cables/wires, switches, enclosures, fuses, ground fault detectors, and more. BOS applies to all types of solar applications.

BoS costs refer to all upfront costs associated with a PV system, with the exception of module costs for instance - costs associated with Land, Civil and general work, Inverters, Mounting structures, Evacuation costs, etc.

It is expected that, BOS manufacturers especially electrical and structural components around the globe are being squeezed as the market landscape becomes more crowded with increasing demand of solar installations in all the sectors be it commercial, utility or residential. I

They can be further categorised as hard costs and soft costs. Hard costs include the costs of inverters, switches, support racks, wiring and batteries/storage systems, and land. Soft costs include costs associated with planning, permissions, customer acquisition, insurance and labour for

t is now important to understand that the future cost reductions are expected to be highly dependent on BOS (e.g. inverters, racking and mounting systems, civil works, etc.) rather than PV modules, despite continued cost reductions expected from modules through 2022.

BOS components include the majority of the pieces, which make up roughly 10%-50% of solar purchasing and installation costs and account for the

Special FEATURE Balancing Cost Vs Quality :

Choosing Mounting Structures

Even though with the inflow of large solar projects is also keeping the market crunched for further developments in new products to reduce the costs. In order to stay competitive, fierce cost cutting and optimisation are being observed across the BoS segment.

The module mounting structures constitute 5%-10% of the total solar plant cost and are responsible for providing structural support to solar panels enabling them to face specific direction and inclination.

Although there is focus on innovations and development for different products based on the market requirements while keeping the cost of BOS competitive in India. In addition, there is an increased focus on augmenting the overall generation of a plant through technology advancements and efficiency enhancement across BoS components.

Inverter Choice Solar Inverters constitute around 10%-15% of the total solar power system cost. Though, inverters are typically expected to last for 10+ years, but their operating life varies considerably upon site conditions, specifically with operating temperature (electronic circuits have a higher failure rate in higher temperatures) and quality of electricity supplied by the grid. Inverter technologies have advanced significantly over the years. In addition to converting DC to AC, inverters now provide several capabilities and services that ensure optimal performance of solar plants like monitoring various parameters which indicate the health of the plant, allowing solar power installer to analyse trends and performance of the solar plant. Moreover, a key trend in inverter technologies is the use of 1,500 Volts (V) systems, which allow developers to optimise the DC losses and costs. Since, solar Inverters are specialized products and a lot of Research, Development and Market Experience goes into producing these. It is therefore critical that the manufacturer is chosen based upon their Experience, Volume Produced and Quality Control.

February - March 2019

While the initial mounting solutions were focused on developing viable support structures, efforts are now being made to improve and simplify the designs by using better materials and providing customised solutions. The mounting structure is available in structural materials like Mild Steel, Galvanized Steel and Aluminium. The weight of mounting structures has reduced at a fast pace in recent years. While this has led to cost reduction, it is important that the weight of mounting structures is reduced in a viable manner, keeping in mind the costs associated with their failure. A good design of mounting structure considers long-term operability, access to maintenance and cleaning of panels. The overall weight of structure should also be optimized, and windloading analysis is a must, to ensure safe operation during high winds.

Trackers Installation Another noticeable trend has been the increasing adoption of solar tracking technologies. The installation of trackers in a solar PV plant can increase the energy generation. The quantum of energy gain varies based on the location. According to industry experts, while the installation of solar trackers will increase the capital expenditure by 9-12 per cent, it will lead to an additional energy output of 18-25 per cent.

Connection & Protection The Balance of System (BoS) which includes Cables (AC and DC), Switchgears (MCB, RCCB, Isolators), Protection Devices (Fuses, Surge Protection, Lightning Protection) and Earthing

Power Insight

Material (grounding conductor, rod, chemicals) together constitutes around 5%-10% of the total cost of setting up a solar power plant in India. The cables should be selected for minimum acceptable voltage drop (typically <1% for DC side and <1.5% for AC side). On the other hand, protection devices are necessary for safe operation of the solar power plant. Fuses help in limiting maximum current in the system, whereas the surge protection device protects the system from voltage surges (AC or DC). Lightning protection device diverts is critical to protecting solar power plant and connected electrical circuit from a lightning strike. Compromising on quality can lead to system failure, thus their ratings and the makes should be selected considering the optimal performance of the plant.

Way Forward: Proper electrical design and workmanship of the solar power plant is by far the most important aspect, and is also critical from safety and operability point of view - thus it is important to select the installer of solar plant wisely. Going forward, the market has to grow while keeping both cost and quality in mind. India is a very acquisition-cost-sensitive market and there is a huge need for us to move from being an acquisition cost to a total life-cycle cost market. Hence, every component supplier can aim to offer solutions that encompass more of the life-cycle and overall project needs rather than the specific component. However, if the supplier can incorporate the land development aspect in the overall costing, it will provide an additional value proposition to the developer. Similarly, the inverter supplier can aim to look at the entire system configuration and not the inverter alone. n
