Ayana Renewables and NTPC Renewable Energy won the Maharashtra State Electricity Distribution Company (MSEDCL) auction to procure 250 MW of flexible and schedulable power from grid-connected renewable energy projects with an energy storage facility on a long-term basis.

Ayana and NTPC won 150 MW and 100 MW, respectively, by quoting ₹9 (~$0.11)/kWh each.

MSEDCL 250 MW of Renewable with Energy Storage Project Auction ResultsThe tender was floated in August this year.

The projects selected under this tender will be eligible for two-part tariffs. These will be referred to as ‘non-solar generation hours tariff’ and ‘solar generation hours tariff.’

The energy supplied during the solar generation hours will be eligible for a tariff of ₹2.42 (~$0.030)/kWh.

The applicable tariff under the power purchase agreement (PPA) will comprise both solar generation hours and non-solar generation hours tariffs. It will be fixed for the entire term of the PPA.

During any contract year, in case the generation is above 10% of the declared annual capacity utilization factor, the successful bidders will be free to sell it to any other entity but the first right of refusal will vest with MSEDCL.

If the energy supply during non-solar generation hours exceeds the required amount of 600 MWh for each 100 MW of contracted capacity, and MSEDCL procures this excess power, the successful bidder will be paid energy charges at 75% of the tariff.

The energy will be dispatched through the scheduling of power in both solar and non-solar generation hours.

It is mandated to deliver the 600 MWh of energy per 100 MW contracted capacity of the project in AC terms daily during non-solar generation hours.

The successful bidders can choose the type and power rating of the energy storage system to be installed in addition to the solar, wind, or hydropower capacity.

The energy storage facility may include a battery energy storage system, pumped storage system, mechanical and chemical systems, or their combinations.

The project can be installed in multiple blocks of at least 50 MW each and connected to the grid. The project can be located anywhere in India.

The project’s energy generation and energy storage components may be multi-located and inject power through multiple interconnection points.

The responsibility of getting the interstate transmission system connectivity and transmission of power up to the interconnection point and energy accounting infrastructure will lay with the renewable project developer.

According to Mercom’s India Solar Tender Tracker, MSEDCL has floated tenders for 20.3 GW of solar power projects.

Mandated energy supply during non-solar generation hours corrected to 600 MWh from 300 MWh.
