The Delhi government on Wednesday wrote a letter to the Centre to urge it to shut down all 11 thermal power plants in the National Capital Region in the backdrop of increasing pollution levels. Delhi Power Minister Satyendar Jain wrote the letter to Union Power Minister RK Singh on the issue and asserted that these plants were the biggest contributors to the Delhi pollution. He also said that the Kejriwal government was the only one in the states which had shut down all its three thermal power plants. Jain also noted in his letter that the Delhi government had shown the path by shutting down its own power plants.
