Reliability Projects

For more than 100 years, Duquesne Light Company (DLC) has remained committed to providing safe, reliable electric service to customers across Allegheny and Beaver counties. We are committed to investing in infrastructure and technology that enable us to meet the increasing demand for energy in the region. A major part of that commitment is ensuring that our electrical infrastructure -- the wires, transformers, substations, poles and other equipment that make up the company's transmission and distribution system - delivers power safely and reliably to your home or business.

As a result, from time to time we must repair and enhance our system. While our infrastructure has served customers well for decades, various components are nearing the end of their useful operating lives. We proactively replace that equipment in order to maintain the levels of service and reliability that you've come to expect from DLC, and to ensure that the region will be able to meet future energy demands.

Current infrastructure improvement and underground residential development (URD) projects occurring across our service territory are listed below. If you are a customer impacted by upcoming work, please see below for scheduling, visit our general project information page for additional information and learn how you can prepare for scheduled outages.

Gibsonia Battery Energy Storage System (BESS) Project
To increase reliability in the Gibsonia area, DLC will install a Battery Energy Storage System (BESS) to alternatively power up to 65 customers. Using this technology during an outage, DLC can re-energize homes from the battery for a few hours while restoration work returns the circuit to normal operating conditions. When the circuit is restored, the customers supplied by the battery will transfer back to the grid source.

Update: As of July 18, 2025, the utility work on the Ridge and Glasgow Road pole lines has concluded. The upcoming work will only be at the battery site on Chatham University Eden Hall Campus.

The borings that were to be drilled July 16 and 17 have been delayed until July 29. This work should be completed by July 30, 2025.

Unless there are any other schedule changes, this is the last of the work planned until construction begins in 2026. Should you have any questions, please contact us at 412-393-6814.
