DOCUMENTATION
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 Coverage
Here are the list of selected AP Nodes in this data product:
| 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 |
| Sub Load Aggregation Points (SLAP) | 20+ AP Nodes |
| Custom Load Aggregation Points (CLAP) | 35+ AP Nodes |
