National standard for Peak Shaving Energy Storage Capacity 2023

Is heat storage a solution to peak shaving in power stations?

Heat storage technology presents a promising solution to this challenge, as it significantly enhances the flexibility of peak shaving in power stations and mitigates supply-demand imbalances within power grids .

Why should thermal power units carry out deep peak shaving?

However, when thermal power units carry out deep peak shaving, their economy will be considerably reduced , and the thermal power units face many problems under low load conditions . Only by changing this situation can we achieve deep integration of thermal power generation and renewable energy development.

What is the energy storage capacity requirement in 2026-27?

As per NEP2023 the energy storage capacity requirement is projected to be 16.13 GW (7.45 GW PSP and 8.68 GW BESS) in year 2026-27, with a storage capacity of 82.32 GWh (47.6 GWh from PSP and 34.72 GWh from BESS).

Can molten salt heat storage be integrated with deep peak shaving?

Due to the substantial capacity and high energy grade of thermal power units, their energy storage requirements encompass large capacity, high grade, and long cycle, the integration of molten salt heat storage with deep peak shaving for thermal power units is still at an early stage of technological development and demonstration application.

How many GW a year will a PSP & Bess storage capacity increase?

By the year 2031-32, this requirement is expected to increase to 73.93 GW (26.69 GW PSP and 47.24 GW BESS) with a storage capacity of 411.4 GWh (175.18 GWh from PSP and 236.22 GWh from BESS).

How much energy storage is needed In 2047?

3.3. CEA has projected that by the year 2047, the requirement of energy storage is expected to increase to 320 GW (90GW PSP and 230 GW BESS) with a storage capacity of 2,380 GWh (540 GWh from PSP and 1,840 GWh from BESS) due to the addition of a larger amount of renewable energy in light of the net zero emissions targets set for 2070.
