The global transformer oil market was valued at approximately USD 2.73 billion in 2023 and is projected to grow at a compound annual growth rate (CAGR) of 12.3% from 2024 to 2030. This growth is primarily driven by the increasing demand in the power sector worldwide and advancements in electric grid technology in developing nations. Each power and distribution transformer utilizes dielectric insulating fluid, which not only offers strong electrical resistance but also helps in maintaining optimal temperatures within the transformer. Bio-based transformer oils are particularly noteworthy for their superior fire resistance and are expected to see the most significant growth through 2030. Given that bio-based oils are entirely non-toxic, they also simplify disposal processes, making them more reliable and environmentally friendly. The rising installation of transformers globally is likely to further increase the demand for bio-based products. Moreover, power utilities are prioritizing the enhancement of safety and performance in both new and existing transformers, contributing to a global uptick in demand for bio-based solutions.
However, stringent regulations imposed by government entities aimed at reducing energy waste pose a significant challenge to product demand. For instance, the U.S. Environmental Protection Agency (EPA) has established strict regulations regarding oil consumption to mitigate electricity waste. Furthermore, both developed and developing nations are increasingly adopting green and environmentally friendly technologies, which may limit the growth of mineral-based products.

Product Segmentation Insights
In 2023, mineral-based oils captured a dominant market share of over 75.6% in terms of revenue. This prevalence can be attributed to their high compatibility and versatility in various applications, including capacitors and circuit breakers. Mineral-based oils are commonly used for conditioning and insulating transformers, as well as in switchgear and boilers. They are also effective for thermal transfer and protecting the internal field windings of transformers. This extensive application of mineral-based oils is expected to drive market growth from 2024 to 2030.
Recently, bio-based products have gained significant traction due to their eco-friendly performance advantages. These products utilize vegetable oil as a feedstock, free from halogens, silicone, and petroleum hydrocarbons. Their non-toxic nature allows them to degrade quickly in the event of spills, presenting growth opportunities for bio-based options.
Products derived from wax-free naphthenic mineral oil offer several benefits, including low cost, easy availability, high efficiency, and excellent thermal cooling capabilities. Nevertheless, the non-biodegradability of these products, which contributes to environmental pollution and handling risks, is expected to limit the demand for naphthenic-based mineral oil products from 2024 to 2030.
