New to CAISO.com the Points of Interconnection Heatmap

The California ISO has launched the Points of Interconnection (POI) Heatmap on Sept. 20, 2024, as part of FERC Order 2023. Access the heatmap from the Generation Interconnection page, under Interconnection facility information.

The POI Heatmap depicts the geographical locations of available capacity on the ISO transmission system to facilitate interconnection customers' decisions on where to develop and submit an interconnection request. Users can run through different scenarios to determine their potential interconnection points. Additional guidance is provided by a self-paced tutorial, which is displayed as a (?) icon at the top right side of the heatmap screen.

A high-level overview of the POI Heatmap was presented during the Resource Interconnection Standards (RIS) Fair on Sept. 17, 2024. The presentation and recording can be found in the Training Center.
