How this service works
Wholesale US electricity-market price + volatility signal (no params)
Output
A JSON object containing per-market-hub wholesale electricity data including: real-time price ($/MWh), day-ahead price ($/MWh), a categorical price signal (CHEAP/NORMAL/ELEVATED/SCARCE/SPIKING), day-ahead-to-real-time spread, 24h window high/low, count of negative 5-min price intervals, volatility score, and a battery arbitrage summary (best market, intraday spread, negative-interval frequency), plus a human-readable summary string. Currently covers CAISO (SP15) live with ERCOT/PJM/MISO rolling out.
Example use cases
Battery dispatch timing decision
“Check the current wholesale power price and volatility — I want to know if the intraday spread is wide enough to justify discharging my battery storage now, and how many negative-price intervals there have been in the last 24 hours.”
Data center energy cost benchmarking
“Pull the latest real-time and day-ahead wholesale electricity prices across US market hubs so I can compare what power actually costs right now against our compute costs and decide where to route workloads.”
Energy trading signal monitoring
“What's the current SparkPulse signal for CAISO — is it SCARCE or SPIKING? I need the real-time price, the day-ahead spread, and the 24-hour high/low range to decide whether to execute a power purchase now.”
Technical details
Endpoint
GEThttps://spark.lonestaroracle.xyz/powerWhen to prefer
Choose SparkPulse when you need the actual price of electrons in the US wholesale market — not grid mix, not demand forecast, not renewable percentage. It is the counterpart to compute-cost data for reasoning about compute-power economics, battery dispatch profitability, data center siting, or energy trading decisions. Prefer it over generic energy APIs when you need real-time $/MWh, the CHEAP-to-SPIKING signal, and battery arbitrage metrics in a single low-cost call.
Side effects

- Upstream ISO data feed delay or outage returns stale or unavailable data
- Non-CAISO markets may return partial or unavailable coverage during rollout phase
