Ester-based Transformer Oil Market, Global Outlook and Forecast 2025-2031

Ester-based Transformer Oil Market, Global Outlook and Forecast 2025-2031

The global Ester-based Transformer Oil market was valued at US$ 67.6 million in 2024 and is projected to reach US$ 110 million by 2031, growing at a CAGR of 7.3% during the forecast period. This significant growth is attributed to increasing demand for eco-friendly and fire-safe transformer oils, especially in regions undergoing extensive grid modernization and expansion.


Biobased or ester transformer oils are gaining attention as sustainable alternatives to mineral-based transformer oils. These oils, either natural or synthetic esters, offer excellent thermal stability, biodegradability, and higher fire points, making them ideal for applications in environmentally sensitive or densely populated areas.

These specialized transformer fluids are designed to perform two essential functions:

Suppression of arcing

Dissipation of heat generated inside transformers

Their superior electrical insulating properties and thermal performance enhance transformer efficiency and longevity.

Ester-based Transformer Oil is a type of dielectric fluid formulated using either natural esters (typically derived from vegetable oils) or synthetic esters (engineered chemical compounds). These oils are utilized in power and distribution transformers for their non-toxic, biodegradable nature, high flash and fire points, and superior moisture tolerance compared to conventional mineral oils. As the power infrastructure evolves towards sustainability and safety, ester-based transformer oils are increasingly favored in new installations and retrofitting applications.
