CAISO (California) 5 Min. RTM LMP Prices for 100 AP Nodes

Overview

This data product offers five minute interval prices for selected 100 Aggregated Pricing Nodes (AP Nodes) in CAISO since 2016. The AP Node coverage of the product is given below.

APNode or APN is an Aggregated Pricing Node (Aggregated Pnode) that can be a Load Aggregation Point, Trading Hub or any group of Pricing Nodes as defined by the California ISO.

LMP is the locational marginal price where demand at that PNode consistent with existing Transmission Constraints and the performance characteristics of resources. The Transmission Provider determines separate components of the LMP for the marginal cost of Energy, Marginal Cost of Congestion, and Marginal Cost of Losses relative to the Reference Bus, consistent with the following equation:

LMP = Energy + Loss + Congestion + GHG

Node Type Number of AP Nodes
Trading hubs (TH) 3 AP Nodes
Default Load Aggregation Points (DLAP) 4 AP Nodes
Energy Imbalance Market Load Aggregation Points (ELAP) 9 AP Nodes
Metered Load Aggregation Points (MLAP) 4 AP Nodes
