How to Submit Applications, Fees and Status Questions
-
Step 1 - Engineering Review
Your application will be received and reviewed by our Engineering Department to ensure that:
- Application has been completed correctly
- All drawings and documentation have been provided.
- Associated fees have been determined and paid.
- The design is consistent with Company policy and State requirements.
Our Company will process the application under the schedule provided for by the rules approved by the Public Utility Commission of Pennsylvania. -
Step 2 - Customer Notification
After the engineering review, you will be notified by email or phone as to whether:
- Application is approved.
- An upgrade and fee is required.
- Information is incorrect or missing in the application.
-
Step 1 - Customer Installation
Following approval of the application, the Customer installs the facility in accordance with the Application, PUC rules and the Company's Requirements for Interconnection of Customer-Owned Generation to the FirstEnergy Distribution System.
-
Step 2 - Customer Agreement & Proof of Inspection
Following installation, the customer submits final completed documents:
- Level 1 Application/Agreement OR Level 2,3 or 4 Agreement
- Certificate of Completion
- Submit evidence of electrical inspection by an authorized inspection agency:
The customer is responsible for contacting their local, city, or county code office for additional permit information and contracting the electrical inspector to schedule an inspection. Upon completion of a satisfactory inspection, the electrical inspector may forward the Certificate of Electrical Approval via the same method as Step 1 above or may sign the Certificate of Completion where designated.
For a list of electrical inspectors, please contact your municipal or county authority. - Level 1 Application/Agreement OR Level 2,3 or 4 Agreement
-
Step 3 - Company Final Review & Approval to Operate
Engineering will:
- Review the as-built installation and final documentation for compliance.
- Determine the need for a witness test as provided for in the regulations and notify customer.
- Finalize documentation and authorize system operation.
- Notify customer of the status of customer's application.
- Arrange for the installation of net energy metering, where appropriate.
Note: Generation interconnection should not be energized prior to electrical inspection and receipt of Certificate of Completion signed by authorized Company personnel -
Step 4 - Company Installs Net Meter
If you receive Approval to Operate, the Company will automatically replace the existing meter with a meter capable of bi-directional registration. Depending on meter availability and other work priorities, this may take several weeks.
Although you do not have to wait until the bi-directional meter is installed to operate your facility, FirstEnergy will not be responsible for tracking and crediting your excess generation until it is installed.You should be aware that depending on the type of meter currently set at your service location:
- Your existing meter could offset your usage by your excess generation, thereby "netting" your energy flows internally, rather than separately registering the energy in and out of your facility.
- Your existing meter may include a feature that prevents it from turning backwards and registering reverse power flow. In this case, even though your facility should reduce the amount of electricity you need to purchase, the electricity your facility generates in excess of your current consumption would not be measured or subtracted from your overall electrical energy use.
- Your existing meter may register the kilowatt-hours your facility is providing to FirstEnergy's system as though they were being delivered to you from FirstEnergy's system. You should not operate your facility in this circumstance since it will result in charges for the energy that you generate. Please check with your installer to ensure that you do not have this type of meter before operating your facility.

Level 4 - Interconnection Fee
Pennsylvania Public Utility Commission - Interconnection Application Fees
Level 4 Applications – In those instances when a Level 4 application is processed using the Level 1, Level 2 or Level 3 review process, the fees set forth for those particular review levels should apply. No fee shall be assessed for an area network impact study conducted under § 75.40. A Level 4 application reviewed under § 75.40(d) should be subject to a base fee of $350 plus $2.00 per kW of the nameplate capacity rating of the Customer- generator’s facility. If an application is denied because it does not meet the requirements of a Level 4 review, and the applicant resubmits the application under another review procedure in accordance with Commission Regulations, the Electric Distribution Company may impose a fee for the incremental expense attributable to the resubmitted application consistent with the fees established for the new level of review.
