SECI plans 2,000 MWh standalone energy storage project

The Solar Energy Corporation of India (SECI), under the administrative control of the Ministry of New and Renewable Energy (MNRE), is planning a 2,000 megawatt-hour (MWh) standalone energy storage system which will be executed by the private sector.

The state-owned solar energy focused corporation has announced that the projects will be incorporated on a build-own-operate (BOO) basis with a 25-year agreement.

SECI has already initiated the project for 2,000 MWh standalone energy system and it will issue a detailed tender by August end, according to PTI.

Further, SECI has issued a notice for selection after which it will enter into an agreement with the successful bidders for 25 years as per the terms, conditions, and provisions.

Given that India has announced its ambitious renewable energy targets (mainly for solar and wind sources) of 175 gigawatts (GW) by 2022, 275 GW by 2027, and 450 GW by 2030.

However, the capacity value of these variable renewable energy sources are limited without grid-scale energy storage.

To comply with that need, NTPC had also on similar lines invited expressions of interest from domestic and global companies for 1,000 MWh of grid-connected battery energy storage system (BESS) on the premises of its power projects across India.

Also, according to a study, the cost for storage was estimated to be $ 203/kWh in 2020 which will come down to $ 134/kWh in 2025. Earlier in the year, SECI had floated a global tender for consultancy services for a 100 MW (AC) solar project along with a 40 MW/120 MWh battery energy storage system (BESS) in Rajnandgaon, Chhattisgarh.
