Solar & Wind Energy in Hyderabad ECBC II, Er. Munavar Basha Submitted by Esther Kiruba 19171NB002 To understand the solar and wind energy in Hyderabad, we have to look at the dat that TSREDCO shows. It shows a sea change in the utilisation of renewable energy sources in the recent years. The installed capacity of renewable energy projects in the State in 2014 was 30-35 MW, and now the capacity has gone up to 4,059 MW with Hyderabad and Rangareddy districts being front runners in adapting renewable energy activities to the maximum extent.1 Out of the 4,059 MW, over 90 per cent of renewable energy was tapped through solar energy with capacity of 3,636 MW followed by co-generation with bagasse (138 MW), wind energy (128 MW), biomass (60 MW) and other sources. Telangana plans to go with renewable energy policies with solar and wind energy (biomass is also a priority since there is a lot of agricultural waste going unused). Hyderabad-based rm plans 600 MW of wind and solar energy projects across Telangana Mytrah Energy (India) Ltd., the Hyderabad-based renewal energy rm, is setting up 400 MW of decentralised solar energy across Telangana in 16 di erent places with the total investment of ₹ 3,000 crore. Wind energy plants are not just mechanical ones but involves lot of technology, arti cial intelligence and sensors because of which e ciencies have increased and the prices have come down enabling the “disruptive” tari rate of ₹ 3.46 for 25 years tied up with the power distribution rms2 1

SOLAR ENERGY: We are damaging the ability of this planet to sustain life every day. Use of fossil fuels for transport and electricity are the biggest reasons for our massive carbon footprint. Among the many small actions, going solar provides a sustainable and concrete way forward to reduce this carbon footprint3. A 3 KW Solar PV plant can save from Rs, 40,000 to Rs. 55,000 per year. In 25 years, the system will for itself at least 5 times over. Solar Power Systems provide a risk-free ROI of 20% on an average during their lifetime.
India is going to be the third largest solar market in the world in the next 2-3 years, with an expected market size of $ 100 billion. The target of 175 GW of solar power production with 40 GW coming from rooftop solar has already pumped more than 10 Lakh jobs into the economy. With such ambitious plans and growth potential, the government has provided multiple incentives to go solar, from tax bene ts to net metering incentives to subsidies. In Hyderabad, it is easy to set up Solar Systems in rooftops: Step 1. Terrace Check & rightsizing the system Step 2: Getting Government Permissions Step 3: Rooftop Solar System Installation Step 4: Switching on the System & Handover Step 5: Online Remote Monitoring & Maintenance Scientists at IIT Hyderabad have developed low-cost, environment-friendly solar cells by employing an o -the-shelf dye used to make kumkum or vermilion in India. The dyesensitised solar cell (DSSC) is based on New Fuchsin (NF) dye with aqueous electrolyte and platinum-free counter electrodes, according to the research published in the Solar Energy journal.

WIND ENERGY: In Hyderabad, Archimedes is producing silent rooftop wind turbines.The silent rooftop wind turbines are capable of generating half of an Indian household's energy needs in a renewable, clean and green way (As wind power is one of the cleanest sources of renewable energy in the world) The sleek, aesthetically good looking windmill yields more energy, produces little noise, is bird friendly apart from looking good. This maintenance free turbine can be xed on top of an apartment, in elds and everywhere. It can rotate 360 degrees into the direction of the wind like a weather wane. The best part is that it also works in low velocity winds from 0.9 meter/Second to as high as 14 meters/ second. In high winds such as 22 meters/second, brakes get activated and the turbine stops to avoid damaging itself. Wind power, as an alternative to burning fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation, consumes no water, and uses little land. Unlike solar power planets, it occupies very little space. It can also be used in combination with solar panels. To help study wind directions and how to position the wind mills a wind rose can be used for analysis. The wind rose for Hyderabad shows how many hours per year the wind blows from the indicated direction4

Mytrah has been running the sole wind energy plant in Telangana at Nazeerabad in Parigi mandal with 48 turbine units spread over 25 km radius and spread over 13 villages generating 108 MW power successfully for last 18 months.
With a high wind capacity of 25.2 metres per second during monsoon (June to August) and 7-12 metres per second otherwise, it has been running round the clock throughout the year with 90 % e ciency, To set up a farm the following steps are taken: Wind Energy, like solar is a free energy resource. But is much intermittent than solar. Wind speeds may vary within minutes and a ect the power generation and in cases of high speeds- may result in overloading of generator. Energy from the wind can be tapped using turbines. Setting up of these turbines needs little research before being established. Be it a small wind turbine on a house, a commercial wind farm or any o shore installation, all of them, at rst, need the Wind Resource to be determined in the area of proposed site. The Wind Resource data is an estimation of average and peak wind speeds at a location based on various meteorological. The next step is to determine access to the transmission lines or nearest control centre where the power generated from the turbines can be conditioned, re ned, stored or transmitted. It is also necessary to survey the impact of putting up wind turbines on the community and wildlife in the locality. If su cient wind resources are found, the developer will secure land leases from property owners, obtain the necessary permits and nancing; purchase and install wind turbines. The completed facility is often sold to an independent operator called an independent power producer (IPP) who generates electricity to sell to the local utility, although some utilities own and operate wind farms directly. Wind mills can be set up ranging scales of:
