At a meeting chaired by Cabinet secretary KM Chandrashekhar on July 28, RGPPL projected that block -1 of 740 MW, which was under repair, would be revived by early January 2008. The company said a total generation of 2,000 MW from the Ratnagiri project, previously Dabhol project, would be possible from January next year. Top sources told FE, "Block-2 which is currently the only operational unit, consists of two gas turbines (GT), (2 X 260) and one steam turbine (ST), (1X220). One of the GTs will be commissioned on gas by July 31 whereas the other GT unit of the same power block, which is currently running on naphtha, will consequently be shut down so that it can be subsequently commissioned on gas. It takes nearly a week's time to convert a liquid fuel power plant into a gas-fired power plant.
The second GT would begin operations by August 15. The commissioning of the 220-MW steam turbine would produce 740 MW in Block-2." Block-1 has been shut down for more than five years now and hence requires comprehensive maintenance and renovation.
Block-1 was run on naphtha during 1999-2001 by the now defunct Dabhol Power Company (DPC) before it was shut down. The block has major technical snags in cooling towers, boilers, turbines and generators. Renovation work is underway on a war-footing as RGPPL has roped in BHEL and GE to bring the block online. As reported by FE, gas for the power plant has already been secured from RasGas, Qatar, on a 2-year contract till September 2009. The gas is priced at $7.8/million British thermal unit (MMBTU) for 1.5 million tonne per annum (MMTPA).
However, the price at the project site has been pared down to around $5.8/MMBTU after a decision was taken to pool the price of older -- and therefore cheaper -- LNG terms contracts with the current RasGas contract.
The RasGas supply of 1.5 MMTPA of regasified liquefied natural gas (RLNG) would not be sufficient to run the third block of the plant. An additional 0.6 MMTPA would be required to run all three power blocks at full capacity.
