New Delhi has proposed that India will provide a village in Bangladesh with solar electric supply as part of the energy cooperation initiative in the SAARC region. The Indian High Commission in Dhaka on Sunday sent a letter to the foreign ministry proposing that Delhi wanted to install solar power systems in one of the villages in Bangladesh for electric supply to 300 home-lights and 50 streetlights. The foreign ministry forwarded the letter to the Power Division on Monday, sources in the division said. In the letter, Delhi suggested that Dhaka should send in the names of 2 or 3 villages to choose one from among. A team of experts of India will select the village after visiting the proposed sites. The letter said Delhi had made the proposal to provide one village with solar power in keeping with the decision on energy cooperation made at the 14th SAARC Summit in April 2007. Sources in the Power Division said the Rural Electrification Board was no Monday advised to send in the names of three remote villages, especially in coastal areas, where it would not be possible for the government to supply power from the national grid.
Reliance Industries headed by Mukesh Ambani has offered to set up a solar power plant in Haryana at an initial cost of Rs 125 crore. Reliance is already setting up two special economic zones in Gurgaon and Jhajjar districts. In a letter written to Chief Minister Bhupinder Singh Hooda, Ambani expressed his desire to set up 5 MW grid-connected solar photovoltaic power plant in Hisar district or any other suitable location. The company has chosen Hisar because it feels that the area has "one of the best possible solar insolation throughout the year in the state. He said his company would progressively expand the project. Appreciating the efforts being made by the Haryana Renewable Energy Development Agency (HAREDA) to promote solar energy, Ambani said the Reliance would like to support HAREDA initiatives. He said an investment in the solar power plant would also help in generating employment as well as in the development of the region.
