Which ESS tenders will increase Indian ESS capacity multifold?

The latest ESS tenders issued by Solar Energy Corporation of India (SECI) and NTPC are the first in India to combine standalone ESS with on-demand use. These two standalone ESS tenders, by SECI and NTPC, have a cumulative storage capacity of 1 GW or 4 GWh. Thus, if executed well, these projects will augment Indian ESS capacity multifold.

What is energy storage systems (ESS)?

Energy Storage Systems (ESS) will be the next major technology in the power sector over the coming decade. The latest standalone ESS tenders from Solar Energy Corporation of India and NTPC will augment capacity manifold and help develop the local ecosystem.

Is ESS Technology still nascent in India?

However, at present, ESS technology is still nascent in India, because of which these standalone ESS tenders will likely face technical, procurement, and regulatory challenges. For example, the NTPC tender requires a 6-hour ESS solution.

What is standalone ESS?

What does ESS stand for?

Standalone Energy Storage Systems (ESS) are rapidly emerging as a key market, with 6.1 gigawatts of tenders issued in the first quarter of 2025 alone, accounting for 64% of the total utility-scale energy storage tendering activity.

What are the challenges facing the ESS industry?

The Standalone ESS industry continues to face persistent challenges such as project cancellations, supply-chain constraints, weak domestic manufacturing and power purchase agreement delays. Players such as IndiGrid and HG Infra Engineering are focused on Battery + ESS (BESS).
