Companies Reluctant To Sign Purchase Agreement Delhi government's ambitious Bawana power project may be running into trouble. The project that was conceived to make the Capital selfsufficient in power generation and inaugurated by Prime Minister Manmohan Singh a few months ago, may not find takers for its power so easily. According to sources, BSES Rajdhani, BSES Yamuna and NDPL have shown reluctance to sign power purchase agreement (PPA) for the 1,500 gas-based plant saying that the power generated from this plant would be too expensive.
