Fort Sill Project

Public Service Company continues to be involved in innovative ways with our communities in the great state of Oklahoma. A newly proposed project with Fort Sill (US Army post near Lawton, Ok) is another great example of how Oklahoma continues to be an energy leader with our communities, and our customers, benefiting from the plentiful resources that are available.

On July 5, 2020, PSO signed a 30-year lease with the U.S. Army for the siting of a proposed energy resilience project at Fort Sill. The proposed project involves the construction of four, 9-megawatt natural gas-fired reciprocating internal combustion engine (RICE) generators, and 10.9 MW of photovoltaic (PV) solar energy.

The proposed project at Fort Sill is the result of collaboration between the Army and PSO. Benefits of the project’s design include the addition of more clean energy to the power grid, and enhanced power quality and energy supply in PSO’s southwest Oklahoma service territory.

The project is also designed to add resilience to the Army with the ability disconnect the new generating facilities from the grid, and then isolate them to supply 100% of the power needed to sustain Fort Sill’s critical missions for at least 14 days. In short, this project, when completed, would provide additional energy to serve PSO customers, but allow Fort Sill’s work and activities to continue with “islandable” power capability in case of a power disruption on the grid.

The proposed energy reliability and resilience project on Fort Sill is an excellent example of collaboration to modernize infrastructure and provide assured access to diverse supplies of energy.

PSO submitted this proposed plan to the Oklahoma Corporation Commission (OCC) on October 5th for their approval.
