April 25, 2012. Expecting an exponential increase in power demand in the island city over the next four years, the Brihanmumbai Electric Supply & Transport (BEST) undertaking has decided to sign another long-term power purchase agreement like the one it has with Tata Power Co. The BEST committee approved the signing of a power purchase agreement with Indiabulls Power for 300 megawatt. The firm will start supplying power from 2016. The state government's proposed Dharavi redevelopment plan and the construction of a business district in Wadala by the Mumbai Metropolitan Region Development Authority are likely to drive this growth in the demand for electricity. As per the agreement with Indiabulls, the company will supply power at ' 3.42 per unit as the base price for 25 years. The current agreement with Tata Power — which will expire in 2016 — is for 932 MW at ' 3.54 per unit. BEST will start a fresh bidding process in 2013-end for a long-term supply of 1,000 megawatts, so that it has the capacity to cater to 1,300 megawatts by 2016.
