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 private energy resources that can be accommodated without adversely affecting power quality or reliability under existing control configurations, and without requiring infrastructure upgrades. Our geospatial portal includes calculated, feeder-level values on our overhead feeders that operate at a voltage class >12kV. These values include the minimum and maximum hosting capacity value, queued private generation, and connected private generation. We will refresh our hosting capacity calculations on an annual basis. Values for queued and connected generation will be updated monthly.

System Data

Peak and Minimum Load Duration Curves We have forecasted 2016 network-level 24-hour peak load duration curves and network-level 24-hour minimum load duration curves based on 2015 historical loads. These curves have been plotted on a single graph along with a capacity curve that indicates the remaining capacity at the substation level. In the case where a substation feeds multiple networks, the capacity has been rated proportionally based on network peak values. Additionally, each network load curve lists the five-year compound annual growth rate.

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.
