SECI Floats Tender for 1200 MW ISTS-Connected Wind-Solar Hybrid Power Projects on ‘BOO’ basis in India


The Solar Energy Corporation of India Limited (SECI) issues bidders for setting up of 1200 MW ISTS-Connected Wind-Solar Hybrid Power Projects in India (Tranche-III) on “Build Own Operate” basis and selling the hybrid power to the SECI. The bidders are required to pay Earnest Money Deposit (EMD) of Rs. 5 Lakh / MW per project in the form of a Bank Guarantee. The last date for submission of bids is February 25, 2020.

 SECI was designated as the nodal agency for implementation of MNRE scheme for setting up of 1000 MW ISTS connected Wind Power Projects. The first wind bid auction under the aforesaid “scheme for setting up of 1000 MW ISTS-connected Wind Power Projects” was successfully concluded by SECI with record low price of Rs. 3.46 per unit of wind power. The prices discovered in this first wind auction were much less than the average pooled power cost of many states. The projects are scheduled to be commissioned within 18 months from the date of issue of the Letter of Awards (LoAs). 

In the recent past, SECI has successfully awarded the LoAs to successful bidders for setting up of 840 MW and 600 MW Wind-Solar Hybrid Power Projects respectively under Tranche-I and Tranche-II both RfS for selection of 1200 MW ISTS-Connected Wind Solar hybrid power projects. SECI shall enter into Power Purchase Agreement (PPA) with the successful bidders selected based on this RfS and Power Sale Agreement.

The present wind power installed capacity in the country is nearly 32.5 GW, sharing around 9% of total installed capacity. Globally India is at 4th position in terms of wind power installed capacity after China, USA and Germany. With the objective to provide a framework for promotion of large grid connected windsolar PV hybrid system for optimal and efficient utilization of transmission infrastructure and land, reducing the variability in renewable power generation and achieving better grid stability, MNRE had recently issued the Wind-Solar Hybrid Policy in May 2018, which was later amended in October 2018. 

A transparent methodology for interstate sale of wind-solar hybrid power is adopted at a price determined through competitive bidding and e-reverse auction process. This will not only facilitate the non-Windy States/UTs to fulfil their non-solar RPO but also boost investment in the sector thus achieving the goal of reaching 175 GW of renewable power capacity by 2022.

SECI shall enter into PPA with the Hybrid Project Developers (HPDs) for a period of 25 years from the date as per the provisions of PPA. The maximum tariff payable to each HPD is fixed at Rs. 2.88/kWh for the entire term of 25 years.

The minimum bid capacity shall be 50 MW, with at least 50 MW of project capacity being proposed at each Project site, and maximum bid capacity under the RfS shall be 1200 MW. The duration of the PPAs and PSAs shall be 25 years from the commercial operation date of the projects. The selection of projects would be technology agnostic. 

For each Project, the minimum Project capacity shall be 50 MW and the maximum capacity shall be 300 MW. The total capacity of wind-solar hybrid power projects to be allocated to a bidder including its Parent, Affiliate or Ultimate Parent or any Group Company shall be limited to 1200 MW. To be eligible to participate in the bid, the net worth of the bidder should be equal to or greater than Rs. 1.00 Crore per MW of the quoted capacity, as on the last date of previous Financial Year 2018-19 , or as on the date at least 7 days prior to the due date of bid submission. 

Also, it is required of the bidder to demonstrate a minimum annual turnover of Rs. 75 lakhs/MW of the quoted capacity during the previous Financial Year (FY) 2018-19 or as on the date at least 7 days prior to the due date of bid submission and internal resource generation capability, in the form of Profit Before Depreciation Interest and Taxes (PBDIT) for a minimum amount of Rs. 15 Lakhs/MW of the quoted capacity in FY 2018-19.

The responsibility of getting the ISTS connectivity and Long Term Access (LTA) shall entirely be at the cost of the HPD.  Such availability of transmission system being dynamic in nature, the Bidder has to ensure actual availability of power injection/evacuation capacity at an ISTS substation. The transmission of power up to, and including at the point of interconnection where metering is done for energy accounting, shall be the responsibility of the HPD at its own cost.

It is required that the project be designed for interconnection with the ISTS in accordance with prevailing CERC regulations in this regard. For interconnection with the grid and metering, the HPD shall abide by applicable Grid Code, Grid Connectivity Standards, Regulations on Communication System for transmission of electricity and other regulations (as amended from time to time) issued by Appropriate Commission and CEA. Minimum voltage level for interconnection at the ISTS shall be 220 kV. The maintenance of Transmission system up and including at the interconnection point shall be the responsibility of the HPD. 

In case of ISTS-projects, minimum capacity for acceptance of first part commissioning shall be at least 50 MW. A project capacity of 100 MW or less can be commissioned in maximum two parts. The projects with capacity more than 100 MW can be commissioned in parts of at least 50 MW each; with the last part being the balance capacity.
