The Department utilizes third-party financed authorities (i.e., Energy Savings Performance Contracts (ESPCs), Utility Energy Service Contracts (UESCs), Utilities Privatization (UP), etc.) as part of its efforts to enhance energy resilience through energy efficiency. In alignment with Installation Energy Plans (IEPs), military installations leverage both appropriated and third-party financed resources to bolster mission assurance and warfighting readiness. Further information on the process and requirements to provide energy services under these contracts can be found below.
