The rules that move the numbers
Negative-price exposure, curtailment, grid fees, support schemes — the framework behind India's battery and PV economics. The same rules that drive our PV-Watcher and BESS-Optimizer.

India has a real power exchange day-ahead market (IEX DAM) with a price ceiling; large viability-gap funding and ancillary-service eligibility are driving a fast standalone-BESS build-out, though discovered tariffs have fallen below many projects' costs.
The Indian Energy Exchange (IEX) runs a real day-ahead market: 15-minute blocks cleared by a uniform Market Clearing Price (MCP, ₹/MWh) — the value this radar tracks. The DAM operates under a regulated price ceiling of about ₹10,000/MWh (₹10/kWh); our data clears at that cap on the tightest hours, confirming the bound. Verify the current cap against the CERC order before modelling.
The Ministry of Power runs a Viability Gap Funding (VGF) scheme for standalone BESS — around ₹91bn (~US$1.09bn) targeting ~43.2 GWh, with 30 GWh approved via the Power System Development Fund (June 2025). VGF eligibility requires a minimum 20% domestic content; the per-MWh support ceiling has been cut as costs fall.
Under the CERC (Ancillary Services) Regulations, 2022, energy-storage systems are eligible to provide secondary and tertiary reserves — a core revenue stream alongside DAM arbitrage.
Discovered standalone-BESS tariffs fell to about ₹1.48 lakh/MW/month (~US$1,576) for 2-hour systems in 2025, and analysts flag that roughly 75% of allocated 2-hour capacity sits in an at-risk-viability band — a gap between auction tariffs and real project costs. Revenue stacking and ancillary pricing still need regulatory refinement.
