ENTERPRISE API · STORAGE
BESS revenue stacking is a black box in India. Every developer's spreadsheet uses different assumptions about hourly price spreads, ancillary participation, and outage-event premia. There is no standard forward price curve, no standard storage revenue model, no public benchmark for what a 100 MW four-hour battery in Bhadla actually earns in 2027. The Storage Revenue Stack API publishes a probabilistic answer — built on the same dispatch backbone as the Curtailment & Capture-Rate API, with model versioning on every response so an investor can replay any past projection against any future model.
WHAT IT DOES
Send the asset (capacity, duration, location) and a market mix across DAM, RTM, ancillary services, and DSM avoidance. Receive a probabilistic revenue stack with the hourly dispatch shape, expected price spreads, and confidence intervals — broken out per market so an investor can see the stack, not a single number.
Solve the dispatch problem for 1-hour, 2-hour, 4-hour, and 8-hour configurations at the same node. Compare revenue per MWh of storage and IRR on each. Convert duration debates into priced answers.
The forward 15-minute price curve at any node, with confidence bands, conditioned on the same production-cost dispatch that drives the curtailment forecast. Use it for revenue modelling, hedge sizing, or PPA structuring.
WHY NOW
SECI's standalone BESS auctions are pricing this implicitly — the FY26 round of 13 GWh-plus proves the market is real. The Ancillary Services Market is operational. The Forecast Scheduling and Plan Mechanism is tightening DSM economics. Brookfield, Macquarie, and KKR are deploying billion-dollar pools into Indian BESS, and they need underwritable revenue models — not spreadsheets that break under credit-committee scrutiny.
SAMPLE
A hypothetical 100 MW four-hour BESS at a Bhadla pooling station, returning a CY27 revenue stack of ₹3,200 per kW-year across DAM (62 percent), RTM (18 percent), ancillary (15 percent), and DSM avoidance (5 percent).
