About the Hosting Capacity Platform
Whether you’re a customer, contractor, or developer, our interactive maps can help you identify potential sites for private generation. Our interactive portal can help guide decisions regarding the interconnection of resources.
Hosting Capacity Platform Basics
Hosting Capacity is the amount of distributed energy that can be placed without requiring system upgrades or effecting power quality. In reviewing the capacity values, you learn that they include minimum plus maximum levels and existing private generation.
Peak and Minimum Load Duration Curves
We have forecasted load duration curves (24-hour) at network peak level for 2016 and minimum level for 2015. They have been plotted on a single graph along with a capacity curve, indicating the substation level’s remaining capacity. When a substation feeds a bigger network, capacity is prorated based on network peak values.
Historical 8760 Load Data
We provide data for each network, including the date/time and load in MW. The 8760 load data coincides with the all-time system peak in July 2013. The 8760 load curve data is a raw data export from a historical archiving system and has not been reviewed and processed (e.g. weather adjusted, evaluated for meter error, fully adjusted to account for distributed energy resource load modifiers) by the methodology applied to the peak hour forecast.
Locational System Relief Value
Locational System Relief Value, or LSRV, is one component of the Value Stack that makes up compensation for Distributed Energy Resources (DER) under the Value of DER structure (pdf). The LSRV is an added credit for DER installations in eligible areas where the utility grid would benefit from additional generation capacity. LSRV areas will display a status of “Eligible” on the Hosting Capacity map under “LSRV Area Information.” For more on LSRV, VDER and the Value stack, visit our Private Generation Tariffs page.
Aggregated Substation Data
As part of the Hosting Capacity Portal we provide aggregated DG values at the substation level. These values are representative of the total amount of DG that is installed on the feeders and networks associated with the area substation. This data can be accessed by selecting a feeder or network on the mapping display and advancing to the associated data pane. Additionally, we have provided the peak substation load for the previous year.
