Regional Review is a year-end series from caa that looks at key developments in a focused industry throughout the year and sets the stage for what’s to come in the near term.
December 2025 — Pittsburgh’s energy sector closed 2025 during one of the most significant shifts in U.S. power demand in almost two decades. National electricity consumption rose an estimated 4% year-over-year, according to the U.S. Energy Information Administration — the fastest annual increase since 2006.

The acceleration was largely driven by AI and digital infrastructure needs. S&P Global Commodity Insights projected a 22% jump in data-center electricity demand in 2025 alone.
Western Pennsylvania’s energy mix — abundant natural gas, a dense network of legacy pipelines, and a nationally recognized engineering talent pool — allowed Pittsburgh to position itself as a resilient, flexible power hub in a period of rising strain on the national grid.
“The unique aspect of our region is that there is a tremendous amount of natural gas production in the same footprint that is served by Peoples,” said Michael Huwar, president of Peoples Natural Gas. “We pass those savings on to customers while investing in modernization that keeps service safe, reliable and more sustainable.”
Peoples Natural Gas advanced one of the largest infrastructure revitalization efforts in the Northeast this year. In 2025, the utility replaced over 250 miles of aging pipeline and added approximately 75 miles of new mainline to support growing residential and industrial demand. Its 18-county service footprint sits directly atop prolific Marcellus Shale output, allowing the region’s natural gas to trade at about $1 below the national benchmark. Peoples’ cost advantage is directly reinvested into system upgrades.
As Huwar emphasized, “This also allows Peoples to invest into modernization efforts that help keep service safe and reliable while increasing the sustainability of our footprint and our system with minimal impact to the customers that we serve.”
Modernization and resilience under pressure
The rise of AI-driven computing is reshaping electricity demand across the country. A recent report by the International Energy Agency (IEA) projects that global data center electricity consumption will more than double by 2030, driven by rapid growth in artificial intelligence, cloud computing and digital infrastructure. This global trend is already influencing regional planning.
In Pittsburgh, utilities and grid operators are preparing for a new generation of power-intensive facilities, prompting long-term capacity upgrades, substation reinforcement, and system hardening to support the digital economy’s expanding footprint.
Sargent Electric Company remained deeply embedded in these modernization efforts.
“In the medium to long term, the biggest drivers for our growth are data centers and the rise of artificial intelligence,” said Rob Smith, CEO of Sargent Electric Company. “When we talk about data centers, we are also highly focused on the new power plants and sources required to support them.”
For Mike Brady, vice president of power generation execution at Liberty Energy, AI marks a fundamental shift in what the grid must be prepared to deliver. “We aren’t just trying to solve today’s problem; we are trying to solve generational challenges,” Brady said, noting that natural gas will remain essential for fast, flexible and low-latency power.
The industry, Brady added, is still at the very beginning of the curve. “We’re only scratching the surface of new possibilities in AI. The energy needed for the computing power, without latency issues, is enormous,” said Brady.
The opportunity for Pittsburgh extends beyond meeting rising demand and into shaping the foundation of the emerging AI economy. “Our goal is to use natural gas to improve the lives of people, create jobs and provide cleaner solutions,” said Brady, adding that powering AI-driven data centers is “one of the most exciting things” they are involved in.
Reclaiming global position
One of the most consequential energy trends of 2025 was the renewed rise of nuclear power. As a recent Goldman Sachs analysis highlights, accelerating AI adoption and the rapid build-out of data centers are reshaping global electricity demand, and meeting this surge could require 85–90 gigawatts of new nuclear capacity worldwide, underscoring why reliable, 24/7 baseload generation is becoming central to national energy strategies.
“In my 40-plus years in the nuclear business, I have never before witnessed such a pronounced need for nuclear power,” said Jacques Besnainou, chief commercial officer of Westinghouse Electric Company to Invest:.
Pittsburgh, the historic birthplace of commercial nuclear power, is once again at the center. The AP1000 reactor — designed in Cranberry and operating successfully in Georgia and China — is now slated for expansion. Federal policymakers signaled support for 10 new AP1000 large modular reactors to begin U.S. construction before 2030.
Westinghouse estimates that this nuclear buildout, coupled with global projects in Poland, Bulgaria and eventually Ukraine, could generate 15,000 new jobs in Southwestern Pennsylvania over the next several years.
