B&W mPower will generate 180MW of electricity and will be a fully underground containment structure.

The companies will collaborate to perform an independent financial review of mPower economics, evaluate alternative potential sites for construction of B&W mPower plants and complete a preliminary pre-licensing analysis.

The study will also assess the need and timing for prospective deployment of B&W mPower plants in the FirstEnergy generation fleet.

FirstEnergy Generation president and chief nuclear officer James H. Lash said, "Completing these studies will help us determine how B&W small modular reactors may be part of our long term generation planning."

"This agreement between FirstEnergy and Generation mPower represents another significant step towards making Ohio a hub for advanced manufacturing and next-generation energy,"

Ohio Senator Rob Portman said, "One or more small modular reactors in our state could not only provide this energy need, but would continue to support advanced energy careers in Ohio.

"I applaud FirstEnergy and Generation mPower for their commitment to advanced energy development and our nation’s energy security," Rob added.
