A case study by ENEL Green Power: FR3-filled transformers chosen to advance sustainability
EGP searched for a proven and tested biodegradable fluid. After much analysis, the insulating fluid selected was Cargill’s FR3® dielectric fluid.

In 2020, ENEL Green Power (EGP), one of the world’s largest and most innovative renewable power developers, kicked-off a project to specify a better transformer for their ambitious “net zero” strategy to eliminate carbon emissions from their value chain.
EGP wase searching for a more sustainable, more reliable, and higher-performing transformer to use in their future solar projects.
The idea of utilizing a Sustainable Peak Load (SPL) transformer, one designed to run at a higher temperature in order to get more power density, filled with a biodegradable ester insulating fluid, emerged as the technology that could help EGP meet their net zero goals.
EGP searched for a proven and tested biodegradable fluid. After much analysis, the insulating fluid selected was Cargill’s FR3® dielectric fluid.
