SECI Kicks Off Storage Push With EOI For 1 GW Project

Highlights :

  • The EOI will mark a major step forward for India’s large storage capacity ambitions.
  • Storage has to grow in step with renewables soon, to ensure smooth grid supplies of power.

SECI has been given the go ahead for inviting expression of interest for installation of 1000 MWh Battery Energy Storage System (BESS) as a pilot project. This is the joint effort of both Ministry of New and renewable energy and Ministry of Power who have been working on this to provide a road map for the installation of the energy storage system in the country.

The installation of large storage projects is considered an important component of the push for 450 GW of renewable capacity by 2030.

SECI’s EOI will come with RFS bid document and the draft comprehensive guideline for procurement and utilization of BESS as a part of generation, transmission and distribution assets and with all ancillary services.

This will be discussed in the pre-bid conference scheduled to be held on 28th October 2021 at 4pm.

Based on the suggestions and the feedback from various stakeholders, the final RFS document will be floated in the first week of November 2021, along with the final comprehensive guidelines for procurement and utilization of BESS as a part of generation, transmission and distribution assets and with all ancillary services.

Going forward, India plans to use energy storage system under following business cases:–

  1. Renewable energy along with the energy storage system
  2. Energy storage system as grid element to maximize the use of transmission system and strengthening grid stability and also to save investment in the augmentation of transmission infrastructure.
  3. Storage as an asset for balancing services and flexible operation. The system operator i.e. load dispatchers (RLDCs and SLDCs) may use storage system for frequency control and balancing services to manage the inherent uncertainty/variations in the load due to un-generation.
  4. Storage for distribution system i.e. it may be placed at the load centre to manage its peak load and other obligations.
  5. As a merchant capacity by the energy storage system developer and sell in the power market
  6. Any other future business models as a combination of the above

The government plans to call bids for setting up around 4GWh of the grid-scale battery storage system at the regional load dispatch centres. The first of the planned large storage systems are expected to come up by early 2023 onwards.

In addition to this, state-run NTPC Ltd has also rolled out a global tender for setting up 1GWh grid-scale battery storage system. According to the Central Electricity Authority of India, there will be a need for 27GW of grid-scale battery energy storage systems by 2030 with four hours of storage.

Coming Up: More Hydro Storage

Apart from Battery Energy Storage systems, there is also growing traction for hydropower projects among Indian clean energy majors.

Here, the country aims to use cheap green power during off-peak hours to raise water to a height and then release it into a lower reservoir to generate electricity. This will help India with cutting the cost of energy generation while gaining the maximum out of Green Energy goals.
