Net-Metered Distributed Energy

Requirements, timeline and checklists to connect to the PPL Electric Utilities power grid

When you’re installing solar panels, CHP, biomass, or another type of distributed energy resource (DER), PPL Electric Utilities is here to help you connect to the power grid. We recommend applying at least 6 months before interconnection service is needed.

For installations under 25 kilowatts (nameplate), you’ll hear from PPL within 3-4 weeks of submitting a completed application. For all other systems, additional reviews and field visits may be required. In addition, for systems 500 kw or larger, PPL must submit our recommendation to the Public Utility Commission. The project must be under scheduling or under construction within one year of application.


Applications should be submitted online at When applying, you’ll need your one-line diagram, site plan and equipment data sheet. For systems of 25 kW or less, email For systems over 25 kW, email PPL will then reply with final approval, which will allow you to activate your system.


If PPL facilities need to be modified, your designer will create your plan and contact you with any estimated fees. A right-of-way agreement is required before new electric facilities can be placed on any property.
