India's First Plant Commissioned by ReGen Powertech, press release
Regen Powertech to launch wind-solar hybrid systems
Chennai, June 13:
Regen Powertech Ltd, one of India’s leading wind turbine manufacturing companies, is all ready to launch wind-solar hybrid systems, the company’s Managing Director, Madhusudan Khemka, has said.While the idea of putting a solar power plant under a windmill is not altogether new, Regen has perfected the system, marrying photo-voltaic plants of either 500 kV or 750 kV with Regen’s 1.5 MW wind turbines. The tweaking has been done in terms of optimising power electronics. The cost of the solar plant would be 20 per cent lower than a standalone solar plant of the same capacity, Khemka told journalists on the sidelines of Renergy 2014, a renewable energy conference-cum-expo, organised here by the Tamil Nadu Energy Development Agency. Answering a question, he said there were always sufficient chunks of land where the shadow of the wind tower would not fall. This is important because if a shadow falls on any part of a solar plant, the generation of electricity of the entire plant will suffer. Khemka did not reveal anything about costs, but said that the economics worked out favourably. Regen, which produces gearless turbines with permanent magnet-based generators using technology licensed from Vensys of Germany, sold 300 MW worth of machines in the twelve months ended March 2014. The company has extended its financial year till September. Khemka said that the company had orders worth 550 MW to be executed this year. “We are extremely busy this year,” he said. He said the company had enough land banks under its control to support 1,000 MW of wind turbine installations.

ReGen Powertech to launch high capacity 2.8MW wind mills, press release
ReGen Powertech to launch high capacity wind mills
A 2.8 MW wind turbine was installed by ReGen Powertech at Vagarai, near Coimbatore. ReGen has so far installed about 1,650 MW of wind capacity, and plans to launch 1.5 MW (with 89 meter rotor diameter) and 2 MW turbines this fiscal.
ReGen Powertech plans to launch its 2.8 MW wind turbines in the international market in March-April next year. In the first year (2016-2017), it hopes to sell about 25 turbines (50 MW to 60 MW). Madhusudan Khemka, Managing Director of ReGen Powertech, told The Hindu here on Saturday that the prototype was installed at a testing site of the company, located about 85 km from here, and was commissioned in April this year. The direct drive (gearless) machine, with 90 metre-long turbine and with 109 metre rotor diameter, was designed for the international market, he said. In the Indian market, ReGen has installed nearly 1,650 MW of wind mills, and plans to launch 1.5 MW (with 89 meter rotor diameter) and 2 MW turbines this financial year. Further, Piramal Enterprises would invest about Rs.275 crore in ReGen Powertech this year. Mr. Khemka said, “We hope to sign the agreement in two weeks. It is a growth capital, and the infusion will be in stages.” He added that “It is basically optionally convertible debentures against our operation and maintenance revenue, and will be used to buy new project sites and create infrastructure.”
Trial run begins
On a six-acre site, located near Dharapuram, rows of solar panels are connected to a common inverter. Also connected to the inverter is a 1.5 MW wind turbine, which was commissioned nearly three years ago. For the last four days, energy generated from the 200 KW solar energy systems and the wind turbine at this testing site of ReGen Powertech is supplied to the grid on a trial basis. The wind-solar hybrid power plant has higher plant load factor (38 per cent) compared to a standalone wind energy system (26 per cent) and the project cost for the plant (which is hybrid and not co-located) is about 15 per cent less compared to a standalone solar project, says Archit Khemka, head of the solar division of ReGen Powertech. The company has been working on the project for the last 9-10 months. This is an in-house developed system, with technical expertise from Provotek, a wholly-owned subsidiary of ReGen. For a 1.5 MW ReGen wind energy farm, 200 KW to 750 KW of solar energy system can be added. ReGen will also provide provisions in its new wind farm projects for the hybrid system. It will import the solar panels and is looking at 50 MW wind-solar hybrid projects this year, he said. ReGen plans to do commercial installation of the hybrid systems from this financial year, said its Managing Director, Madhusudan Khemka, and Chairman of Indian Wind Turbine Manufacturers’ Association.
