POWERGRID wins 150 MW/300 MWh BESS in APTRANSCO's 2 GWh tender
PGCIL's first BESS win under TBCB — part of Andhra Pradesh's 1,000 MW/2,000 MWh storage procurement across seven substations.
Power Grid Corporation of India (POWERGRID) received a Letter of Award for a 150 MW/300 MWh BESS project in Andhra Pradesh on December 29, 2025 — its first standalone storage win under tariff-based competitive bidding (TBCB).
The project
- Location: 400/220 kV Kalikiri substation, Chittoor district, AP
- Scope: 150 MW/300 MWh, build-own-operate, “on-demand” usage
- Tariff (per Mercom): ₹1,64,000 per MW per month
- Timeline: commission within 18 months; 12-year BESS purchase agreement
The award is part of APTRANSCO’s 2 GWh (1,000 MW × 2 hr) procurement across seven substations — winners included Bondada Engineering (225 MW), Ecoren Energy (500 MW across two sites), Bhagwati Group (75 MW), Legion Energy Products (25 MW) and SVR Electro Projects (25 MW).
Why POWERGRID matters
A central transmission utility winning storage under competitive bidding is significant — it signals the grid operator treating batteries as a transmission-side asset, not just an IPP play. The project carries VGF support through PSDF.
