SECTION-2 Invitation to Tenderers(Bidders)

and Instructions to the Tenderers(Bidders) [ IT & IT ]

1.0 INTRODUCTION / INTENT OF GSECL:

1.1 Gujarat State Electricity Corporation Limited (hereafter named as GSECL), formed in August 1993, a wholly owned Govt. of Gujarat company, is authorized to generate electricity energy in the state through different power plants which includes Thermal, Hydro,Gas based PP and also renewable source of energy like Solar, Wind etc.

Amongst them, Dhuvaran power station is Gas based power plant located at Dhuvaran Dist: Anand (Gujarat) where combined cycle power plants CCPP-I and CCPP-II are under operation and CCPP-III is under construction as detailed here under :

Details of Generating Capacity Sr.No. Unit No.

Gas Turbine Steam Turbine

Total

Operating Since

1 CCPP-I 67.850 MW 38.767 MW 106.617 MW 28.01.2004

2 CCPP-II 72.510 MW 39.940 MW 112.450 MW 01.11.2007

3 CCPP-III 240.00 MW 136.10 MW 376.1 MW Under construction

At present, due to shortage of Gas and other reasons beyond control of GSECL,

above referred CCPP-I & CCPP-II are not able to operate at their rated designed

capacity . Moreover day by day the cost of gas is on increasing trend. To mitigate

above problems, GSECL intent to install Integrated Solar Combined Cycle (ISCC)

Power Plant of suitable capacity on BOOT ( Design, Finance, Build, Own, Operate

and Maintain, Transfer) basis at Dhuvaran Dist: Anand (Gujarat) and

integration/supply of generated steam of required parameters at the required point

in HRSGs of existing CCPP-I and CCPP-II, payable charges to be on usable

steam enthalpy basis. Based on this, the agency shall be finalized through

competitive bidding process. The integration point of solar steam in existing

HRSG of CCPPs and the point of feed water intake to solar power plant from

existing CCPPs have been fixed and shown elsewhere in these tender bid

documents. Schematic Diagram for the above is attached herewith at Annexure-II.

Accordingly bidder is required to install solar thermal power plant having capacity

of steam generation to meet the requirement equivalent of 5 (FIVE) MW Electrical

power generation on BOOT basis.

1.2 The additional electricity thus generated shall be sold to GUVNL as per the terms and condition agreed upon with the respective companies.
