You must notify DLC, by filing an Interconnection Application Agreement, that you plan to install a qualified, renewable energy generating system, so that the proper metering can be installed. Your system must be installed according to the Standards for the Connection of Generating Facilities, which are operated in parallel with DLC's "Standards for Connection."

The following customers, listed by rate classification, are eligible to participate in our Net Metering service, provided approval has been given from DLC:

  • Residential Service (RS)
  • Residential Service Heating (RH)
  • Residential Service Add-on Heat Pump (RA)
  • General Service Small and Medium (GS/GM)
  • General Service Medium Heating (GMH)
  • General Service Large (GL)

Your rate classification is listed in the top right-hand corner of the first page of your monthly DLC bill.

For additional information, please view the Rider No. 21 -Net Metering Service of DLC's current tariff. If you have chosen an alternative electric generation supplier, please view this FAQ.

Net Metering is the means of measuring the difference between the electricity generated by a customer connected to our system and the electricity provided by DLC. Please view this FAQ if you have chosen an alternative electric generation supplier. A bi-directional meter is used to measure and record the flow of electricity in both directions. The electricity generated by the customer's alternative energy generating system offsets part or all of the customer's kilowatt-hour usage. Through the Net Metering service, you will receive a credit for the amount of electricity you send DLC in excess of the power we send you during a monthly billing cycle.

Each month you will receive a credit for the amount of electricity received by DLC in excess of the power we send you during your billing cycle. If you have chosen an alternative electric generation supplier, please view this FAQ.

If you supply more electricity to DLC than what you have used in a given billing period, the excess kilowatt-hours will be carried forward and credited against your usage in subsequent billing periods at the current retail rate. During the annual May 31 true-up process, we compensate customers, at DLC's current price to compare, for any excess kilowatt-hours generated over the amount of kilowatt-hours we delivered. If you have chosen an alternative electric generation supplier, please view this FAQ.

The full retail rate applies to the following charges:

  • Generation
  • Transmission
  • Distribution
  • Pennsylvania Tax Adjustment

The price to compare (PTC) applies to the following:

  • Generation
  • Transmission
  • Pennsylvania Tax Adjustment

DLC requires a W-9 form (Request for Taxpayer Identification Number and Certification) on file for all customers that participate in our Rider 21 Net Metering Service. During the annual May 31 true-up process — when we compensate customers for any excess kilowatt-hours generated over the amount of kilowatt-hours we delivered — DLC is required to issue a Form 1099 if you are entitled to a refund that meets or exceeds $600. If you have chosen an alternative electric generation supplier, please view this FAQ.

Yes, you still will be responsible for the customer charge (which covers our costs for meter reading, customer billing, service equipment, implementation of advanced metering technology and other expenses), and any minimum charges that are applicable to your rate classification. (Your rate classification is listed in the top right-hand corner of the first page of your monthly DLC bill.) You can view the Schedule of Rates posted on our website.

If you select an alternative electric generation supplier, it is your responsibility to alert them of your participation in DLC's Rider 21 Net Metering Service. Your supplier may require you to sign a contract or provide them with additional information to allow them to properly service your account. Please be aware that the annual true-up payment is the responsibility of the company that supplies your electricity. If you choose another electric supplier, DLC no longer will provide an annual true-up payment since it is not providing the power supply.

There may be costs to connect, depending on the customer equipment chosen. The customer would have to pay DLC for any upgrades to our system that may be needed to connect their renewable energy source to the grid. The customer also may have to purchase and install additional equipment other than the renewable energy source based on the equipment and size of system they purchase.

There are many different types of renewable energy generation systems and each one may have their own specific requirements, so please contact the Interconnection Coordinator at DLC at Interconnection@duqlight.com to discuss specific systems and requirements to connect to the grid.

DLC will install a net meter at no cost to the customer. If the customer wants a special or different type of meter, the customer would bear the cost and it would have to be approved by DLC.

As part of the interconnection process with Duquesne Light, your current electric meter will be replaced with a net meter that can track your energy production as well as your energy consumption.

You may be aware that Duquesne Light is in the process of exchanging existing electric meters with new advanced digital meters as part of an overall upgrade of the company’s metering infrastructure required by Pennsylvania Act 129 (check the Meter Exchange Section of DuquesneLight.com for more information). If you already have received a new digital meter, it will be replaced with an advanced digital meter that will be net-metering capable.

If you have not yet received a new digital meter, your existing meter initially will be replaced with a standard digital net meter. When it is time for Duquesne Light to begin installing advanced digital meters in your neighborhood, Duquesne Light will mail a notification letter advising you of the upcoming exchange to an advanced digital model with net metering capability.

The net meter will be installed once a successful witness test has been completed. This witness test will take place after your contractor has submitted the Certificate of Completion to Duquesne Light. For the status of your Certificate of Completion submission, please contact your contractor.

Upon successful completion of the witness test, a net meter will be installed within 7-10 days.

Customers may turn on their generation once a net meter has been installed. You will receive an energization letter at the email address provided on your application when the net meter has been installed.

Energization of your system prior to DLC installing a net meter may result in billing issues.

Please call our Customer Service department at 412-393-7100.

Yes, there could be a limit to how much excess generation DLC will purchase. Limits are reviewed by DLC through the application procedure and are based on a first-come, first-served basis.

Customers are not allowed to generate power onto the DLC system during a power outage. The customer's generating system must disconnect from the DLC system during a power outage for the safety of our workers.

DLC does not offer, sell or install renewable energy generating systems — the customer must purchase and get engineering support (if applicable) for the specific type of equipment you want to install. Customers must receive approval from DLC for any system that you want to purchase and install whether you connect to the grid or not.

This is something you must investigate yourself. Only you can decide which renewable energy generating system is right for you. You may visit the National Renewable Energy Laboratory's website to obtain additional information

More information can be found in Rider No. 21 of DLC's current tariff.

Additional information about renewable energy and tax credits can be found at: www.energystar.gov or www.energy.gov.

Residential customers with electric water heaters may be eligible for a $286 rebate for installing certain "Energy Star" solar water heaters as part of DLC's Watt Choices program. For more information, please visit the rebates section of wattchoices.com.
