Every market an Indian battery can earn from.

A battery doesn't earn from one market, it earns from the best market, block by block, all day. Sparko forecasts and bids across all of them.

The markets

Seven places to play, one engine.

DAMDay-Ahead Market

The base market. Bids for tomorrow clear once, around midday, for every 15-minute block. This is where Sparko sets the day's core charge/discharge plan.

ClearsDay before delivery
Battery earns byPrice arbitrage across the day
RTMReal-Time Market

Rolling auctions that gate every 15 minutes on the delivery day. Sparko uses it to chase intraday price spikes and to recover any day-ahead bids that didn't clear.

ClearsEvery 15 min, same day
Battery earns byIntraday moves & recourse
GDAMGreen Day-Ahead Market

A day-ahead market for renewable energy. Relevant for green-linked storage and assets that want to trade clean power at a premium.

ClearsDay before delivery
Battery earns byGreen price spreads
HP-DAMHigh-Price Day-Ahead

A scarcity segment with a higher price ceiling, used when the system is tight. Sparko forecasts whether it will clear and positions the battery for the upside.

ClearsScarcity conditions
Battery earns byPeak-scarcity discharge
SRAS·TRASAncillary reserves

Getting paid to stand ready. SRAS (secondary) responds automatically to grid frequency; TRAS (tertiary) is dispatched on instruction. Batteries are ideal, fast, precise, always on.

Battery earns byAvailability + activation
DSMDeviation Settlement

Not a market to trade, a penalty to avoid. Deviating from schedule is charged (or paid) against grid frequency. Tighter forecasting keeps a battery inside the penalty-free band.

CongestionArea Clearing Price (ACP)

When the grid can't move power freely between regions, prices separate by area. The premium between your area's clearing price and the national market clearing price is a real, forecastable edge, Sparko predicts where and when the grid will split, so the battery is on the right side of the constraint.
