In a Nutshell

• Customers who generate their own electricity with  renewable energy sources can interconnect with the grid and receive bill credits for excess generation
• Green Power Connection™ (GPC) is Pepco’s process for facilitating small generator interconnections and net energy metering (NEM) requests
• Small generator technologies that qualify for NEM and interconnection with our system include solar (photovoltaic or “PV”), wind, biomass, anaerobic    digestion, geothermal electric, fuel cells using renewable sources, hydro, and micro-combined heat and power (up to 30kW). See our GPC website for more details
• Title 15 of the D.C. Municipal Regulations (DCMR) defines the interconnection and net metering regulations and application processes Pepco follows. Chapter 40 sets out the District of Columbia Small Generator Interconnection Rules (SGIR) and Chapter 9 sets out the Net Energy Metering Rules and defines Pepco’s net metering application process

• A fully completed and signed District of Columbia Interconnection Application and Agreement and fee are required. Most residential systems qualify for the Level 1 application; see the SGIR for details on the Level 2, 3, or 4 application 
• For customers who wish to feed generation back into the grid and receive bill credits, a fully completed and signed District of Columbia Customer Net Energy   Metering Contract (NEM Contract) also is required and a net capable meter installed at your premise 
• Apply online at www.pepco.com/gpc
• The interconnection application is a two part process, and the NEM Contract is a separate document altogether. See the back of this sheet for the components and requirements of both
• Pepco will calculate and invoice the contractor for the application fee

Part I requires:

• Customer of record contact information (name, mailing and email address, phone numbers)
• Equipment and electrical contractor information
• Facility information (utility and electric supplier serving the facility, utility account number)
• Renewable Generator System Information
• Inverter manufacturer name and model number
• Alternating Current (AC) generator nameplate rating
• System design capacity 
• Generator type (PV, reciprocating engine, fuel cell, etc.)
• Energy source (solar, wind, hydro, cogeneration, microturbines etc.)
• Estimated commissioning date
• Customer’s signature
• Application fee, which Pepco will calculate and invoice contractor
• A single line drawing of the system and a site map 

DC Customer NEM Contract requires:

• Customer of record contact information (name, Pepco account number, address, phone numbers, email address)
• Generator manufacturer name and model number
• Energy or source type (PV, wind, fuel cell, cogeneration)
• Nameplate rating AC or DC (in kW)
• Facility location
• Customer’s signature  

Part II of the Interconnection Application requires:

• Customer and system information must match the Part I submission
• Certification of Completion
• Inspection Certificate (with clearly identified system type)
• Customer’s signature The Level 2, 3, and 4 Interconnection Application and Agreement requires additional information. See the application for details.

Where do I start? 

Prior to installing or operating a generating facility, customers are required to apply and receive Pepco’s written approval. Details are on our website.

How do I apply? 

Complete and submit the interconnection application at Pepco.com/gpc

Does the net-capable meter measure total generation? 

No. Generation occurs on the customer side of the meter. Any energy generated is first fed inside the premise for electrical use by the appliances, electronics, lights, etc. 

How can I see the amount of electricity I generate? 

Many systems come furnished with a monitoring device that shows generation. Discuss this with your contractor. 

Are there other factors to consider? 

Yes. Electricity generation will fluctuate based on several factors — clouds, darkness, and dirty or snow-covered solar panels all limit generation. We recommend that you understand how your system will operate under varying conditions. You may still receive a Pepco bill even though you are generating electricity.

Why would my interconnection application to be delayed or 

denied? 

Applications will be delayed if required information is incomplete or missing, documents are unsigned, or fee payment is not received. In some regions, our utility may not have an open circuit, making net metering interconnection unavailable. 

Can you recommend a reputable installer?

No. We recommend you research and consult with an installer or contractor by using publically available resources. If you work with a contractor, it is your responsibility to ensure they are using the appropriate forms, fees, and documentation throughout the interconnection process.
