PPL Electric and DOE showcase federally funded grid technologies at Allentown training center

On September 2, 2026, PPL Electric Utilities and the U.S. Department of Energy brought federal grid-modernization funding into plain sight — live demonstrations, working hardware, and all. They held a joint public showcase at PPL Electric’s Walbert Training Center in Allentown, Pennsylvania. PPL Electric President Christine Martin and DOE Office of Electricity Assistant Secretary Katie Jereza both spoke. Attendees got to see three grid technologies backed by the federal GRIP program up close and in action.

Joint event highlights federal-utility grid partnership

The September 2 showcase wasn’t just a ribbon-cutting. It was a working demonstration designed to show how federal dollars are turning into real hardware on Pennsylvania’s grid. PPL Electric and the DOE picked the Walbert Training Center deliberately — it’s where PPL’s crews train, which makes it a fitting backdrop for technologies meant to change how those crews do their jobs.

Christine Martin framed the event around operational impact. “Our work with the Department of Energy is helping us move promising technology into real-world operations, where it can help us identify problems sooner, limit the impact of outages and support faster restoration for the communities we serve,” she said. Assistant Secretary Katie Jereza echoed that from the federal side, calling the PPL partnership a model for how utilities and government can work together to deliver practical grid improvements.

Operators get a window to schedule targeted maintenance, extend equipment life, and avoid the kind of unplanned outages that are hardest for customers to absorb.

The GRIP program — Grid Resilience and Innovation Partnerships — provided the funding.

GRIP program funds PPL Electric’s Grid of the Future projects

GRIP is the engine behind PPL Electric’s Grid of the Future initiative. The federal grant covers a range of hardware and software projects: smart reclosers, predictive-failure sensors, underground infrastructure upgrades, modernized grid-control systems, and an improved digital model of the electric system. That’s a broad portfolio, and it reflects just how interconnected modern grid modernization has become.

Jereza connected the program to the broader Powering America 250 initiative, which the DOE describes as prioritizing affordability, reliability, and grid security as core pillars of national energy policy. “PPL Electric’s work shows how federal and utility partnerships can accelerate practical grid improvements that benefit customers and communities,” she said.

Federal grid investment can feel abstract — big dollar figures, long timelines, distant outcomes. The Walbert event was a deliberate effort to make the work visible and concrete, showing what GRIP funding actually looks like when it moves from a grant announcement into field-ready equipment. That distinction mattered to everyone in the room.

Three technologies demonstrated at Walbert Training Center

The centerpiece of the event was three live demonstrations, each targeting a different layer of grid reliability.

Single-phase smart reclosers are already part of PPL Electric’s existing smart grid infrastructure. They work by automatically isolating faults — when something goes wrong on a line, the recloser limits how many customers lose power by containing the problem to a smaller section of the network. Through the GRIP-supported project, PPL Electric plans to add up to 250 more of these devices, with anticipated reliability benefits covering roughly 28,000 customers and a particular focus on rural areas where outages can be harder to address quickly.

Predictive-failure monitoring sensors take a different approach. Rather than responding to problems after they happen, these sensors detect signs of deteriorating or damaged equipment on distribution circuits before failure occurs. Operators get a window to schedule targeted maintenance, extend equipment life, and avoid the kind of unplanned outages that are hardest for customers to absorb.

Low-tension network automation addresses underground electric networks specifically. The upgrades add advanced relays, sensors, fiber-optic communications, and remote-monitoring capabilities to systems that have historically been harder to observe and manage — helping operators spot issues faster, cut unplanned outages, and improve safety for the workers maintaining those underground systems.

Each technology targets a different failure mode: fault isolation, equipment degradation, underground network visibility. That’s why the combination matters as much as any individual piece.

Expected operational and customer benefits

Taken together, the hardware and software components are designed to work across both transmission and distribution systems. The practical goal is straightforward: fewer outages, shorter outages, and better information for the people managing the grid in real time.

Real-time visibility is a recurring theme across all three technologies. When operators can see what’s happening on the system — demand shifts, distributed energy fluctuations, fault locations — they can reroute power more effectively and balance supply and demand more safely. That capability grows more important as distributed energy resources and electric vehicles continue connecting to the grid in larger numbers.

AI and machine learning enhancements are part of the plan as well. The Grid of the Future project includes IT upgrades intended to support those increased connections, though these are described as intended improvements rather than completed deployments.

PPL Electric serves approximately 1.5 million homes and businesses across eastern and central Pennsylvania, according to PPL Newsroom. At that scale, even incremental improvements in outage prevention and restoration speed translate into meaningful reliability gains for a lot of customers. The Walbert showcase was a public signal that those improvements are moving from planning into practice — backed by federal funding, demonstrated with working equipment, and aimed at a grid being asked to do considerably more than it was originally designed to handle.
