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.

System Data

Peak and Minimum Load Duration Curves
These network curves shows a representative load profile of the forecasted hourly peak (maximum) loads for 2018, and a representative load profile on light loads (minimum load) for the networks (based on 2017 data).  The maximum (peak) load hourly profile curve and minimum (light) load hourly profile curve are plotted on a single graph along with the capacity (in MW) of the substation supplying that network.  The substation capacity may also be supplying additional load for another network and/or radial load area.

Forecasted 8,760 Load Data

The 3-year, 8,760 network forecast utilizes the General Electric-Multi-Area Reliability Simulation (GE-MARS) program to modify the actual hourly loads from the previous year based on monthly energy distribution from the previous year, forecasted peak demand, and energy send-out. Con Edison uses the most recent actual hourly loads to capture the Distributed Energy Resources (DER) impacts embedded in the service area to develop the load shapes for the individual networks. We adjust the load shapes to the individual network peak demand and energy send-out forecasts, including the projected DER impacts, such that the forecast includes the impact of load modifiers. We provide localized 8,760 hour forecasts to assist developers in considering the application of DER in our service territory. The 8,760-hour forecasts are for informational purposes. These forecasts have uncertainties, such as weather and hourly load curves, as well as the typical inherent forecasting error, including, but not limited to economic drivers, customer decisions and/or behavior, and forecasted DERs. Con Edison does not warrant the accuracy of these informational forecasts.

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.
