Explore where you can connect Distributed Energy Resources (DER), such as solar or battery storage, to the power grid without triggering infrastructure upgrades.
Overview
Our hosting capacity map visually displays the available capacity for new distributed energy resources across different sections of the electrical grid. It's generated by analyzing grid characteristics, existing loads, and potential impacts of new connections. Areas with high available capacity are typically green, while constrained areas are red, indicating where upgrades would be needed to accommodate more.
Hosting capacity refers to the amount of Distributed Energy Resources (DER) that can be added to the grid without negatively affecting power quality, reliability, or triggering system upgrades. These values offer an estimate only. They do not replace the need for a formal utility engineering study (CESIR).
If you're using synchronous generation, be aware that these systems can contribute to high fault current, which may overload protective equipment. Before applying, review mitigation options like:
Reducing total generator size
Using induction or inverter-based generators
Fast-acting fuses or AC-to-AC DC links
Additional Information and Resources
Locational System Relief Value (LSRV)
LSRV is a compensation plan that offers added incentives for DERs in high-value grid areas. Look for “Eligible” indicators on the map or visit our Distributed Generation Tariffs page for more info.
Aggregated Substation Data
At Con Edison, we share helpful information about how much distributed generation (DG) is already installed in your area. You can find these totals at the substation level. To explore the data, simply click on a feeder or network in our hosting map.

The local voltage shows the voltage that the circuit is operating at when there is a switch from one-line section to another. The substation distribution voltage shows the voltage of the initial run.
Available data can be downloaded through the attribute table, which is the icon of a square with one vertical line and four horizontal lines running through it. Once the attribute table is open, the user can export the data as a CSV for the entire system or only for those locations currently being displayed. The data can also be filtered through Excel.
The filter tool under “options” allows sorting based on feeder value. This information can be exported to Microsoft Excel for additional analysis.
No. The provided values indicate the minimum and maximum values in MW.
There may be. If there are, they would be indicated during the Coordinated Electric System Interconnection Review (CESIR) process. The map assumes operation from 10 a.m. to 8 p.m. and assumes that the energy storage will operate from full charge to discharge.
The Hosting Capacity data that is being provided is for information purposes only and is not intended to be a substitute for the established interconnection process. The analyses presented in these displays provide the feeder level hosting capacity for the distribution circuits evaluated. Hosting Capacity is an estimate of the amount of DER that may be accommodated without adversely impacting power quality or reliability under current configurations and without requiring infrastructure upgrades. Please note that this analysis was conducted under current configurations, without installed DER, and prior to infrastructure upgrades such as; installing a recloser or remote terminal unit at the Point of Common Coupling, replacing a voltage regulating device or controller to allow for reverse flow, substation-related upgrades including 3V0 protection, or other protection-related upgrades.
For the Stage 2 displays, each circuit’s hosting capacity is determined by evaluating the potential power system criteria violations as a result of large PV solar systems with an AC nameplate rating starting at and gradually increasing from 300 kW interconnecting to three phase distribution lines. The analyses represent the overall feeder level hosting capacity only, and do not account for all factors that could impact interconnection costs (including substation constraints). Please note that issues related to circuit protection require further analysis to make a definitive determination of hosting capacity. This data is being provided for informational purposes only and is not intended to be a substitute for the established interconnection application process.
Additional displays with tabulated data have been included in the form of data pop-up displays to indicate that the hosting capacity may be lower at any given location. As previously mentioned, existing DER is not considered in this stage of the hosting capacity analysis, and the data pop-ups are intended to provide additional context to the displays. For these reasons, the installed and queued DG values in the data pop-ups have been included and will be updated on a monthly basis.
