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.

PSO's Fort Sill Energy Resilience Plan

If approved, PSO customers can expect the following benefits:

  • More clean energy added to the grid. The combination of clean-burning natural gas and renewable from the sun supports PSO's long-range plans to put more of our abundant, home-grown natural resources to work serving Oklahomans.
  • Enhanced reliability. The addition of nearly 47 megawatts of electric generation helps assure a plentiful supply of power to serve the growing needs in our state.
  • Economic development. Business and industry wanting to build, expand or relocate are attracted to regions where there is an abundant, diverse and reliable energy supply.
