Increasing urbanisation, efficient land use, effective asset management, capability for renewable generation & battery storage integration, changing load profiles, regulatory changes, sustainability, financial prudence, and, critically, reducing human and environmental risk, are all factors that influence utilities companies and substation designer’s decisions.

These factors are now converging in many cases, especially in more populated locations, to make the use of mineral oil in substations expensive in terms of mitigation or even untenable given that alternatives are available. Ester liquids have become an established alternative that enable cost and carbon savings in substation designs due to being less flammable and readily biodegradable, while also delivering operational flexibility and potential to extend asset life. This presentation will set out a case for the adoption of esters as the standard dielectric liquid for substations.
