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 can be attributed to the continuous expansion of the global power sector and the advancements being made in electric grid infrastructure, particularly in emerging economies. Transformer oils are crucial for every power and distribution transformer as they serve as dielectric insulating fluids that offer high electrical resistance and help maintain the transformer’s temperature by keeping it cool.

Among the various types of transformer oils, bio-based oils are expected to experience the highest growth during the forecast period, primarily due to their superior fire-resistant properties compared to traditional mineral-based oils. Bio-based oils are non-toxic, which not only makes them safer to handle but also easier to dispose of in an environmentally friendly manner. The increasing global installation of transformers and the growing preference for environmentally sustainable products are further driving the demand for bio-based transformer oils. Additionally, power utilities are focusing on enhancing the safety and performance of both new and existing transformers, which is likely to further fuel the demand for bio-based transformer oils in the coming years.

However, the market faces challenges, primarily due to stringent regulations imposed by government agencies aimed at reducing energy wastage. For example, the U.S. Environmental Protection Agency (EPA) has established strict rules on oil usage to minimize electricity losses. Moreover, both developed and developing countries are increasingly adopting green and environmentally-friendly technologies, which may hinder the growth of mineral-based oils. As a result, these regulations and the shift toward sustainable alternatives could restrict the market's expansion for mineral-based transformer oils while boosting the demand for bio-based oils.

Regional Insights

Asia Pacific led the transformer oil market in 2023, holding a dominant revenue share of over 55.2%. This dominance can be attributed to the increasing demand for electricity in both developed countries like Australia and rapidly growing economies such as China, India, and Japan. As these nations continue to expand their energy infrastructure, there is a rising need for reliable power distribution systems, which directly contributes to the growing demand for transformer oils. Additionally, the expansion of commercial and industrial sectors in the region is expected to drive the construction of more substations, thereby increasing the demand for transformers and, consequently, for transformer oils.

A key factor driving this growth is the substantial investments in the power sector, which are enabling the market penetration of Chinese manufacturers. China, in particular, is seeing considerable growth in its renewable energy capacity, especially in wind and solar power, which is further boosting the demand for transformer oils in the sub-transmission segment. However, the presence of strong domestic manufacturers in countries like China and India presents a significant challenge for foreign companies trying to enter the Asia Pacific market, as local players often have a cost advantage and are more familiar with regional regulations and market dynamics.

In North America, the growth of the transformer oil market is being driven by the expansion of industrial and manufacturing sectors in both the U.S. and Canada. The ongoing technical upgrades and modernization efforts in existing transformers are also contributing to market growth. As older transformers are replaced or retrofitted to improve efficiency, there is a growing demand for high-quality transformer oils. Furthermore, the regional market is benefiting from a declining crude oil market, which could help reduce the cost of transformer oils derived from mineral sources. These factors combined are expected to support the continued growth of the transformer oil market in North America.
