WATT FUEL CELL COMPLETES INSTALLATION OF ITS LATEST GENERATION FUEL CELL SYSTEM, WATT HOME™, WITHIN PEOPLES NATURAL GAS SERVICE TERRITORY

Locally made fuel cell systems can serve as backup power source for homes by connecting to existing natural gas infrastructure

WATT Fuel Cell, in partnership with Essential Utilities, has successfully installed the next-generation WATT HOME solid oxide fuel cell system in Peoples Natural Gas’ Western Pennsylvania service territory. The installation marks a significant step forward in enhancing energy efficiency and reliability for residential customers.

The WATT HOME system is a cutting-edge technology designed to provide safe, clean, efficient, and reliable energy directly to homes. This system operates by converting natural gas into electricity through an electrochemical process without combustion, offering a sustainable complement or alternative to traditional energy sources.

The installation of a WATT HOME system brings numerous advantages to the homeowner and community at large. Those advantages include increased efficiency, reduced greenhouse gas emissions, and a smaller physical footprint. As a back-up power solution, the WATT HOME system provides a dependable source of electricity, minimizing the impact of grid outages.

With the increasing strain on the PJM electric grid from extreme weather events and the retirement of baseload generators, the need for reliable backup power has never been greater. On average, U.S. electricity customers experience approximately 5.5 hours of electricity interruptions annually. WATT HOME fuel cell systems keep the lights on during outages without the noise or pollution created by standard backup power generators.

"The rising frequency and severity of power disruptions highlight the urgent need for resilient, efficient, and clean energy solutions,” said Caine Finnerty, CEO and Founder of WATT Fuel Cell. “When the power goes out, the WATT HOME system activates to ensure your electricity is working all the time.”

Looking Ahead: Future Installations and Rollout Program

As part of Peoples’ commitment to advance innovative energy solutions, Pennsylvania’s largest natural gas utility plans pilot installations of the WATT HOME system in multiple company field offices. These projects will help define the installation and operational process across different use cases, informing a future public rollout.

“The partnership with WATT is the latest in a series of innovative concepts championed by Peoples to meet modern-day energy demands,” said Peoples President Michael Huwar. “The WATT HOME system’s groundbreaking technology has the potential to protect homeowners from volatility in power generation, offering a reliable, resilient and sustainable energy solution that leverages our region’s abundant natural gas supply.”
