Trombay Power Station

Trombay Power Station is a 1580 megawatt (MW) thermal plant in Mumbai, Maharashtra, India. Unit 5 (500 MW) and Unit 8 (250 MW) are run on coal, Unit 6 on oil, and Unit 7 on gas. Tata has proposed converting the 500 MW Unit 6 from fuel oil to imported coal, and submitted a draft environmental impact assessment report for the proposal in October 2012. (For more detail on the proposed upgrade see Trombay Power Station Proposed Conversion of Unit 6 to coal-fired).

Background
Trombay Power Station was established in 1956 to provide power to the city of Mumbai. Unit 6 was operational in 1990 and runs on fuel oil. Tata Power has said the rising cost of fuel oil has led the company to propose conversion to imported coal.

Coal imports
Approximately 2.4 million tonnes of coal for the existing coal-fired units is imported by a project specific coal berth. Tata Power has proposed that the capacity of the Trombay Coal Terminal be expanded to 4.4 million tonnes a year and an additional coal storage area be built.

Coal for the power station is supplied from Indonesia. In March 2007 Tata Power purchased a 30% stake in two coal mines owned by Bumi Resources --PT Kaltim Prima Coal (KPC) and PT Arutmin Indonesia (Arutmin). Announcing the deal, Bumi stated that Tata Power had entered into a "long term" coal off-take agreement with KPC "for the supply of approximately 10 million tonnes per annum at index linked prices for its power plant at Trombay in India as well as for future power projects, including the recently won Ultra Mega Power Project of 4,000MW at Mundra in India."
