Data honesty. CAISO (NP15 / SP15) is pulled from the public CAISO OASIS API and is current to the latest market interval.
PJM, ISO-NE, MISO, BPA Mid-Columbia, Palo Verde and ERCOT are shown as historical reference (last refreshed Dec 2025) — their live feeds are pending EIA API integration and will switch to live automatically once connected. Negative prices are real, not errors: they signal oversupply windows where a battery should be charging.
