Markets
One market today.
ERCOT is in beta. PJM, CAISO and MISO are coming soon: for those we list what we will check, and show no results.
ERCOT Beta
Our first market. Coverage is in beta: the charge types below are being built and checked.
Coverage
In scope for the beta.
What we are building to check, with the status of each.
- Real-time energyIn beta: five-minute prices, settled per fifteen-minute settlement interval; from public telemetry an approximation.
- Day-ahead energyIn beta: awarded quantities and settlement point prices, from the day-ahead disclosure ERCOT publishes for each storage resource.
- Ancillary servicesIn beta: Regulation Up, Regulation Down, Responsive Reserve, ERCOT Contingency Reserve and Non-Spinning Reserve, from published awards and prices.
- Energy storage set point deviationResearch only today: the charge is documented, not yet computed.
- Reliability deployment price adderResearch only today: no adder price series is held yet.
Limits
What public data cannot show.
Exact real-time energy needs the settlement-grade meter data held by the asset's scheduling entity. From public telemetry it is an approximation, and we label it as one.
Day-ahead energy and ancillary services are computed from published awards and prices.
