Standalone BESS, BESS + Solar, FDRE, RTC, PM-KUSUM and solar-pump benchmarks — who floated it, when the e-RA was held, who won, what the cell and container cost that day, and whether the tariff clears Growthifye's financial model (equity IRR ≥ 15%, project IRR ≥ 12%, DSCR & current ratio ≥ 1.2).

PCS costed as grid-forming (GFM) · CEA advisory CEA-PS-11-20(12)/1/2026-PSPA-I (Advisory dated 10 July 2026; clarification on applicability issued subsequently) · +2.0% on storage capex · wording as reported, official verbatim pending desk confirmation
“The Central Electricity Authority (CEA) has advised the implementation of 100 percent Grid-Forming Inverters (GFMs) in all upcoming Battery Energy Storage System (BESS) projects. GFM BESS must be capable of stable operation across a wide range of system strengths, including weak-grid conditions corresponding to an SCR of 2.0 or lower at the point of interconnection, and must provide autonomous and near-instantaneous frequency and voltage support. A short-term current overload capability of at least 1.5 pu for a minimum of 200 milliseconds is recommended; the BESS must be capable of damping power-system oscillations within the 0.1–20 Hz range. GFM controls must remain operational whenever the BESS is connected to the network and must not change operating mode during network disturbances. Active-power response to RoCoF events must begin within 5 milliseconds and be maintained for at least five seconds; reactive-power reaction time is capped at 5 milliseconds with a response time of not more than 30 milliseconds following a voltage change; the BESS must withstand a momentary voltage phase-angle jump of up to ±60 degrees without disconnecting. GFM BESS with an aggregate capacity of 50 MW and above must be capable of providing black-start support, participate continuously in AGC on a 24x7 basis, and support seamless bidirectional operation with no cooling period between charging and discharging. The advisory takes effect from 10 July 2026 and applies to all upcoming BESS projects of 50 MW and above; BESS projects for which bids are concluded by 10 August 2026, or where purchase orders were placed before 10 July 2026, are not required to comply.”
