Stromfee.US · D2 · Revenue potential per market

▶ Explainer · ~37 s

The menu of US revenue streams for a battery: DAM arbitrage · FMM/RTM · Regulation Up/Down · Spinning/Non-Spinning Reserve · Resource Adequacy. ALTERNATIVES per hour — not additive.

Where does arbitrage arise?

One megawatt can only be in ONE use at a time. US ISOs co-optimize energy and ancillary services, so the market itself allocates the battery to its highest-value use each hour. Resource Adequacy (capacity contracts) stacks on top as a monthly $/kW-month payment in California.

Who earns what — and where?

US market roles, cleanly separated (FERC market design).

Power marketer / Scheduling Coordinator (SC)

Makes the allocation decision through its bids: energy spread vs. ancillary awards vs. RA commitments.

Asset operator

Sees which market qualifications (telemetry, AGC capability, RA deliverability) are worth building.

Investor

Assesses the breadth of revenue sources — diversification lowers risk; shallow AS markets saturate.

Utility & ISO/RTO

All shown products are wholesale/ISO domain; utilities buy RA from storage but don't trade it.

Data status: Live US ancillary-service prices are not yet in our database — this page stays a concept page until they are. Day-ahead energy data (CAISO, ISO-NE) is already live in D1/D3.

Settlement-quality data: the potential shown here only becomes real revenue if it can be cleanly settled — revenue-quality meter data and ISO settlement statements decide what is billable. Stromfee builds exactly this transparency layer. (How we solved it in Germany: metering-data deep dive.)
