We support renewable energy and partner with our customers to ensure safe and reliable interconnection of renewable energy and other distributed energy resources into the electric grid.
The Hosting Capacity map gives an indication of how much generation (expressed in kW) can be added to a feeder before the feeder reaches capacity or other limitations that reduce the reliability of service to electric customers on the feeder.
Although the values are meant to provide the user with a general idea of availability, space on the desired feeder is not guaranteed and/or may change at any time. All applications for interconnection will still require a full review and may also require additional interconnection costs.
Hosting capacity is not an exact science. Results shown may understate the hosting capacity and results will be revisited in the future. For more details, please consult the “Criteria Summary.”
Due to the amount of data, the map may take a minute to load. Thank you for your patience.
Please note that the aggregate limit of large distributed energy resources is 3 MW on 12/13 kV, 6 MW on 25 kV, and 10 MW on 34 kV. Any system over 250 kW is considered to be "large." After the aggregate large limit is reached, 250 kW or smaller systems can continue to be added until another circuit or substation violation would be reached.

Please note NJ state rules and levels may be different (see “Criteria Summary”).Customers applying for a Level 1 application cannot be sized above 10 kW and must be inverter based.
Spot network customers who want to apply for a Level 2 application must only be serving one customer, and the system must be limited to less than five percent of the spot network peak load or 50 kW, whichever is less .
Customers on an area grid network applying for a Level 3 system cannot be greater than 50 kW, with no single-phase system larger than 20 kW, and the aggregate maximum injection is five percent of the peak load or 50 kW; whichever is less.
Applications (Level 4) for systems larger than Level 2 or 3, on either a spot network or an area grid network will be reviewed by our engineering team. A photovoltaic system should not cause inadvertent network protector operations and may require additional monitoring or controls, such as reverse power relays to insure proper network protector operations.

The technological, legal, and regulatory considerations that apply to interconnection of solar generation and other distributed energy resources are complex and constantly evolving. To the best of Pepco Holdings' knowledge, the information presented on this map was accurate in all material respects as of September 2018. However, Pepco Holdings, Atlantic City Electric, Delmarva Power, Pepco, and their affiliates cannot guaranty the accuracy of the information found on this map. Please seek appropriate technical, operational, financial, and legal advice before proceeding. NOTE: The hosting capacity of the secondary network was published June 2017 and has not and is not currently able to be updated.
