The locational marginal price (LMP) is the wholesale cost of electricity at a specific point on the grid for a single five-minute interval. It bundles the marginal generator's cost with congestion and losses, and it is the number traders, battery operators and large buyers watch most closely.
CAISO settles three trading hubs — NP15 (north), SP15 (south) and ZP26 (central). Vatio exposes all three as a single hub parameter, updated on the same five-minute cadence as the market.
NP15, SP15 and ZP26, five-minute intervals in $/MWh, with history on the paid tiers. One endpoint, one key.
