This federal contract award, valued at $47,000.00, was made by the Department of Energy's (DOE) National Energy Technology Laboratory (NETL) to the Electric Power Research Institute (EPRI), a non-profit research organization. The contract is for testing and evaluation of various optical fiber-based sensors, including acoustic sensors, gas sensors, and distributed temperature sensors, using EPRI's custom oil-filled transformer model system. The purpose is to cross-validate the performance of these improved sensors compared to prior tests conducted at EPRI's facility in 2022. The contract does not have a set-aside designation. EPRI, as the parent organization, has a strong track record of providing technical services and research support to federal agencies like the DOE, Department of Defense, and Nuclear Regulatory Commission across energy domains such as renewable energy, fossil energy, and grid modernization.
