SECI tenders 3 GW ISTS connected solar power projects


SECI has issued a request for selection (RfS) document for inviting bids for setting up 3 GW ISTS – connected solar power projects to be installed anywhere in India. The scope of the developer involves land, connectivity and long term open access.

The solar pv projects are based on Build Own Operate (BOO). BOO is a project model in which a private entity receives a concession from private or public sector, or government to finance, design, construct, own and operate a design facility.

SECI will enter into Power Purchase Agreement (PPA) with successful bidders for a period of 25 years based on terms, conditions and provisions of RfS. The maximum tariff payable to the project developer is fixed at INR 2.93/kWH for 25 years.

Already commissioned project will not be considered under RfS. Projects under construction or projects, which are not yet commissioned will, however, be considered, if these projects are not already accepted under any central or state schemes.

Selection will be carried out through e bidding and followed by e reverse auction process, details of which are given in RfS document. Bid submissions are due on April 27, 2018.


The minimum capacity to be installed at a single location ( termed as a block) should be 25 MW and installed capacity of the single block should be multiples of 25 only. A package is a cumulative installation of 50 MW and above to be interconnected at single CTU substation. A package of 50 MW shall consist of two separate blocks at different locations.

The project may consist a number of packages each being in multiple of 25 MW and the minimum capacity of each package shall be 50 MW. The minimum voltage level of the single block shall be 33 kV and for a single package shall be 220 kV.

A single tariff has to be quoted by bidder for entire project. PPA’s should be signed separately for each package. The bidders are responsible for obtaining connectivity and long term open access (LTA) for each package.
