Reference guides for the ERCOT wholesale electricity market — nodal LMP pricing, Day-Ahead and Real-Time markets, ancillary services, congestion, settlement points, price spikes, API data access, and energy cost optimization for Texas industrial loads.
View Our SCADA & Programming ServicesERCOT uses a nodal pricing market design where electricity prices are calculated individually at thousands of settlement points across the Texas grid. Prices are determined …
ERCOT uses nodal pricing where each bus on the grid has its own price reflecting local generation cost, transmission congestion, and losses. ERCOT switched from …
How transmission congestion creates price differences between ERCOT nodes, and how Congestion Revenue Rights (CRDs) are used to hedge location basis risk.
ERCOT's Day-Ahead Market clears hourly prices the day before. The Real-Time Market produces 5-minute prices during actual dispatch. Deviations from DAM schedules settle at RTM …
ERCOT LMPs consist of three components: energy (system-wide marginal cost), congestion (location-specific transmission constraint cost), and loss (marginal transmission losses).
ERCOT has four settlement point types: resource nodes (~700+ for individual generators), load zones (Houston, North, South, West), hubs (financial trading references), and private use …
ERCOT ancillary services include Regulation Up/Down, Responsive Reserve (RRS), Non-Spinning Reserve, ECRS, and Fast Frequency Response — procured to maintain grid reliability.
ERCOT's four load zones (Houston, North, South, West) for market pricing and eight weather zones for load forecasting — how each works and how location …
How to access ERCOT market data programmatically using the ERCOT API — settlement point prices, DAM results, RTM prices, and integration with SCADA for automated …
What causes ERCOT price spikes, how VOLL caps and ORDC work during scarcity, Winter Storm Uri impact, and how industrial loads can prepare for extreme …
How industrial loads interact with ERCOT nodal pricing — retail contract structures, demand response, real-time price monitoring, direct market participation, and energy cost optimization.
How ERCOT settles wholesale transactions — two-settlement system, statement timelines, preliminary and final settlement, uplift charges, and how to read settlement statements.
