Global Transformer Oil Market - Outlook and Forecast 2022-2027

Market Overview

The global transformer oil market is projected to experience a Compound Annual Growth Rate (CAGR) of 6.36%, reaching a value of $3.45 billion by 2027, up from $2.38 billion in 2021. This growth can be attributed to the thriving construction and infrastructure industry, which has led to an increased demand for electricity in residential and commercial sectors over the past few years. As a result, the transformer oil industry has witnessed significant expansion. The global transformer oil market can be segmented into two key categories: end-users and oil type. The transmission and distribution segment is one of the largest segments within the end-user category, while mineral oil remains the dominant oil type used in the production of transformer oil by most companies.

By 2027, the global transformer oil market volume is expected to reach 2,584.99 kilotons. Transformer oil, also known as insulating oil or dielectric fluid, is a stable oil that exhibits excellent electrical insulating properties even at high temperatures. It is primarily used in wet transformers or oil-filled transformers, as well as certain high-voltage switches, circuit breakers, and capacitors. The main purpose of transformer oils is to insulate and regulate temperature. Therefore, transformer oil must possess specific properties such as high dielectric strength, chemical stability, thermal conductivity, and long-lasting performance.

Electricity distributors and industrial manufacturers regularly carry out maintenance activities to prevent transformer malfunctions and disruptions in electricity distribution. Moreover, the growing global population and increased use of various appliances have resulted in a higher per capita electricity demand. Consequently, the global transformer oil market is expected to witness significant growth due to these factors. Additionally, manufacturers in the transformer oil market have made substantial investments in Research and Development (R&D) to develop enhanced products with extended service life, effective oil purification, and reduced environmental impact.

In Asia, cross-border electricity trade is on the rise, with countries like India, Bhutan, Nepal, Bangladesh, Sri Lanka, Thailand, Malaysia, and Singapore establishing electrical grids for this purpose. This trade can be either bilateral unidirectional or bilateral bidirectional. The evolving electricity industry in India is expected to bolster cross-border electricity trade in South Asia. Similarly, several countries in the region have implemented net-zero emission policies, which are projected to drive the demand for renewable power generation. This surge in renewable power generation is anticipated to increase cross-border electricity trade. Existing cross-border electricity trade among South Asian countries, including India, Bhutan, Bangladesh, and Nepal, has laid a foundation for stronger relationships that could facilitate regional electricity trade.

Industrialization is a key driver of economic growth in emerging economies, with China and India leading the way. In 2021, around 37 emerging countries accounted for 80% of the global population and approximately 70% of the world’s Gross Domestic Product (GDP) growth, according to the International Monetary Fund (IMF). Emerging economies, particularly India, China, and Brazil, offer lucrative opportunities for the electricity industry due to their large populations. The oil & gas, agriculture, automotive, and pharmaceutical industries are major contributors to electricity demand in these economies. Consequently, the electrical grid is expanding in emerging economies to meet the growing electricity demand driven by industrial development. This expansion will likely lead to increased usage of various transformers for electricity transmission and distribution, thereby driving the demand for the transformer oil market.

Dry-type transformers are stationary solid-state devices that require minimal maintenance. Unlike liquid-filled transformers, they utilize high-temperature insulating technologies, making them environmentally friendly. These transformers provide a safe and reliable power supply without the need for fire-resistant vaults, emissions of toxic gases, or catch basins. Their safety features make them suitable for applications requiring fire safety, such as schools, buildings, hospitals, factories, and chemical plants. Dry transformers do not use liquid silicone or oil to cool the core and coils, resulting in lower production and maintenance costs. Consequently, the demand for dry transformers is expected to increase, potentially impacting the transformer oil market negatively as the need for oil-filled transformers may decrease.

Market Segmentation

The market is segmented based on various factors, including oil type, end user, and geography.

Segmentation by Oil Type
Mineral Oil
Silicone Oil
Bio-based Oil

Segmentation by End User
Transmission & Distribution
Power Generation
Railways & Metros

Segmentation by Geography
North America – US, Canada

The global transformer oil market can be segmented based on end users, including transmission & distribution, power generation, railways & metros, and others. Among these segments, transmission & distribution is anticipated to be the largest, with a market value of USD 1.10 billion in 2021. This is primarily due to the significant reliance on transformers within the transmission & distribution industry.

Mineral oil currently dominates the transformer oil market, being the largest segment. Its popularity stems from its compatibility with various additives. However, the dominance of mineral oil is expected to decline in the future with the emergence of silicone-based and bio-based transformer oil. Additionally, developed countries such as the U.S., Germany, and Japan have expressed concerns about the environmental impact of mineral oils, leading to the implementation of stringent regulations for transformer oils.

The Asia Pacific (APAC) region holds the largest share in the global transformer oil market and is projected to surpass USD 1.4 billion by 2027. The rapid development of infrastructure, increasing population, and demand from industries such as food & beverage, aerospace, automotive, power generation, and manufacturing contribute to APAC’s prominence. Moreover, the power generation sector is expected to experience substantial growth in APAC, driven by the region’s burgeoning population.

South Asian countries engaging in cross-border electricity trade have also stimulated demand for transformer oil. While APAC currently dominates the industry, there are other countries with significant potential for transformer oil development that may challenge APAC’s dominance. North America and Europe, with their well-established industries and high electricity requirements, present strong contenders.

North America, ranking as the third-largest market for transformer oil, is projected to grow at a considerable rate of 5.70% during the forecast period. The oil & gas industry significantly contributes to North America’s economic development, as it is the world’s largest crude oil producer. Additionally, the region serves as a major hub for the manufacturing sector, supporting industries such as automotive, oil & gas, chemicals, and more. With a strong presence of industrial lubrication manufacturers and headquarters of major companies like ExxonMobil, Valvoline, and Petro Canada, North America exhibits high demand for transformer oil.

In conclusion, the global transformer oil market is influenced by various end users, with transmission & distribution being the largest segment. Mineral oil currently dominates the market but may face challenges from silicone-based and bio-based alternatives.
