KEY POINTS
-
DOE announced a $4.2 billion investment program for nuclear-power projects in Pennsylvania and Ohio.
-
The investments would preserve nearly 4 gigawatts of baseload power and add 433 megawatts of nuclear capacity.
-
The program is expected to support approximately 3,000 project-related engineering, construction and planned-outage jobs.
Investment Would Preserve Existing Capacity
The U.S. Department of Energy (DOE) announced a $4.2 billion investment program for nuclear-power projects in Pennsylvania and Ohio, targeting existing and new capacity as electricity demand rises across the PJM Interconnection region.
The Oct. 5 DOE announcement said the investments would preserve nearly 4 gigawatts of reliable baseload power and add 433 megawatts of new nuclear capacity. Nuclear makes up around 30 percent of PJM's fuel mix, second only to coal, according to a review of its public power data Oct. 9.
DOE said the funding would " finance nuclear uprates and modernization across Vistra’s nuclear fleet in Pennsylvania and Ohio." Texas-based Vistra is a retail electricity and power generation company.
The DOE funding is expected to support approximately 3,000 project-related jobs in engineering, construction and planned-outage work, in addition to preserving thousands of permanent jobs.
US Grid Operators at the Forefront: "Air Traffic Controllers of the Power Grid":
PJM is one of the largest transmitters of electricity in the US, serving approximately 67 million customers, according to its website.
PJM, and similar grid operators, or regional transmission organizations (RTO) manage and monitor the electric grid across multiple U.S. states.
In a factsheet explaining their role, PJM wrote, "We’re sometimes called air traffic controllers of the power grid. PJM monitors and coordinates more than 1,400 generating sources and 88,333 miles of high-voltage transmission lines. Just like air traffic controllers, we don’t own the equipment."
The PJM Interconnection region covers transmitting electricity through all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia.

ConstructConnect: Power Infrastructure Construction Continues to Accelerate
ConstructConnect Associate Economist Devin Bell noted that, "Power Infrastructure construction continues to accelerate nationally. ConstructConnect forecasts a 30.1% increase in Power Infrastructure starts in 2027 compared to full-year 2026."
Bell mentioned that the increased power infrastructure construction, "has followed rapid data center construction, which continues to strain the electrical grid." [Read the ConstructConnect Data Center Report]
"Goldman Sachs Research forecasted in May of this year that U.S. data center electricity demand would double from 2025 to 2027, going from 31 GW to 66 GW", Bell added.
The Program Includes New Construction and Maintenance Work
DOE said the projects are intended to strengthen the grid, lower energy costs and meet growing demand across the 13-state PJM region. The program includes work that would extend the operating life of existing reactors as well as investments tied to additional generation.
The program would create work across new generation, plant modernization and planned outages. Those scopes typically require specialized engineering and construction crews, equipment suppliers and nuclear-qualified contractors.
Stay Connected: Project-Level Details Remain Unclear
DOE did not identify the individual plants, contractors, construction schedules or project-by-project allocations.
The announcement therefore leaves open how much of the $4.2 billion program will flow to new construction, plant modernization or outage-related work.
