The power situation in the national capital of Delhi faces a massive shortage of 900 mw in another three years, a high powered environment committee has warned in a strategy paper submitted to the Supreme Court. "By 2002, it is estimated that Delhi's peak power demand will increase to about 3500 mw but the total availability under the most optimistic of circumstances will not exceed 2600 mw," the Environment Pollution (prevention and control) Authority (EPCA) said in its "strategy paper on power sector in Delhi."
