Transformer Oil Market Size

Transformer Oil Market size was valued at USD 2.7 billion in 2022 and is set to grow at over 6.8% CAGR from 2023 to 2032. The growing global population, industrialization, and urbanization have led to a significant rise in electricity consumption. This increased demand for electricity necessitates the expansion of power infrastructure, including transformers, which in turn drives the demand for transformer oil. A large number of power grids worldwide are aging and require modernization and refurbishment. Upgrading existing transformers with new and efficient ones, along with the use of high-quality transformer oil, becomes crucial to ensure the reliable and safe operation of the grid, and further aid in boosting the product penetration globally.

The transformer oil market growth is due to the ongoing deployment of efficient transformers in response to the increasing electricity demand across the globe. This expansion of the industry will be further propelled by a growing emphasis on rural electrification initiatives and substantial funding support from non-profit organizations. The global transformer market is expected to witness at around 7.1% growth rate during the forecast timeframe. Mineral based transformer oil industry is set to cross USD 3.5 billion by 2032.

COVID-19 Impact

The outbreak of COVID-19 had a significant impact on the transformer oil market, primarily due to country-wide lockdown measures and the closure of manufacturing and industrial sectors. This resulted in the postponement of ongoing projects and various other factors that affected the market. The impact was particularly pronounced across North America and Asia Pacific as a large number of transformer oil producers are located in the U.S. and India, and they faced challenges due to lower demand in developing nations.


Furthermore, the pandemic led to a decrease in transformer oil prices, as the reduced demand and disruptions in the supply chain affected the market dynamics. Agricultural nations also faced the issue of stockpiling transformer oil, as demand was lower, resulting in increased storage capacity requirements and higher production costs, leading to a decline in the transformer oil industry.


It is worth noting that the impact of the pandemic varied across regions and was influenced by local circumstances, government policies, and the severity of the outbreak. As the situation evolves and economies recover, the market is expected to gradually stabilize, but challenges and uncertainties may persist in the near term.


Transformer Oil Market Trends

The transformer oil market is poised to grow due to stringent legislative measures aimed at developing a reliable grid network and the increasing demand for electricity. Furthermore, favorable regulatory reforms that support the expansion of sustainable energy networks, along with government policies such as feed-in-tariffs, will contribute to the growth of the industry.


Dielectric insulating fluid, which provides high electrical resistance and helps keep transformers cool, is filled into power and distribution transformers. Among different types of transformer oil, bio-based products are expected to witness the highest growth during the forecast period, attributed to their superior heat resistance properties. Moreover, the rising demand for power has necessitated the installation of new transformers, which is anticipated to accelerate the expansion of the U.S. transformer oil market.

The mineral-based transformer oil market is projected to exhibit a CAGR of 6.5% through 2032. The widespread availability and compatibility of mineral-based oils with high voltage transformers have led to their increased adoption across various industries. Factors such as good oxidation stability and high temperature viscosity have also contributed to the growing demand for these oils. However, bio-based alternatives are set to gain a competitive advantage over mineral-based oils in the market in the coming years.


The naphthenic mineral-based oil segment witness remarkable growth till 2032, due to their superior solvating power and performance at lower temperatures compared to paraffinic oils. This has resulted in increased adoption of naphthenic-based oils in developed nations, driven by their easy availability and substantial reserve base. Consequently, the product landscape is expected to diversify further. Additionally, the market for bio-based transformer oil is experiencing strong growth, attributed to the growing awareness of biodegradability and environmental sustainability. This trend is reinforced by stringent unofficial regulations related to environmental protection and emissions reduction.
