Diversifying into power
GSPC Group decided to move into power generation as a part of its corporate diversification plan and embarked on a short gestation power project based on the use of natural gas from its gas fields. The Hazira area of Gujarat was chosen as the site for its first combined cycle power plant. To implement the project, GSPC promoted a separate company named Gujarat State Energy Generation Ltd (GSEG).
GSEG, in turn, selected Alstom as contractor for the project through international competitive bidding. Alstom supplied the plant on a turnkey basis. Its scope included two GT8C2 gas turbines with generators, a steam turbine with generator and heat recovery steam generators as well as the overall power plant control system. The contract also included civil works, balance-of-plant and buildings. GSEG employed Desein Consulting Engineers of Delhi as advisors and to supervise the turnkey contractor's compliance with the plant specification.
GSEG selected Evonik Energy Services (India) Private Ltd erstwhile Steag Encotec as O&M contractor for the project. The power purchase agreement for the project was signed with GUVNL (erstwhile GEB).
Project Development Highlights
Gujarat State Petroleum Corporation Ltd. (GSPC), engaged in Oil & Gas E & P, decided to diversify into downstream activities for value addition in the energy business and thus, GSEG was incorporated in December 1998.
