The Federal Energy Regulatory Commission approved an accounting petition filed by Waverly Light and Power that allows utilities to capitalize all costs incurred to retrofill a transformer with bio-based dielectric coolant, for the enhanced performance and extension of useful life of the transformer, under the FERC Uniform System of Accounts. The bio-based dielectric coolant, Envirotemp FR3 fluid, is produced by Cooper Power Systems.
Envirotemp FR3 fluid is a sustainable alternative to traditional mineral oil, offering numerous benefits, including exceptional fire-resistant properties and a reduced environmental impact, in addition to its demonstrated ability to extend the life of a transformer’s insulation system. The bio-based fluid is listed in the USDA BioPreferred program, and is derived from 100 percent edible seed oil, making its biodegradation rate and completeness meet the U.S. Environmental Protection Agency (EPA) criteria for “Ultimate Biodegradability” classification. Envirotemp FR3 fluid received the first published EPA Environmental Technology Verification for transformer materials.
