Transformer Oil Market Size & Trends

The global transformer oil market size was estimated at USD 2.73 billion in 2023 and is anticipated to expand at a compound annual growth rate (CAGR) of 12.3% from 2024 to 2030. This is attributed to the steadily growing power sector globally, along with advancements in electric grids in emerging economies. Every power and distribution transformer contains dielectric insulating fluid with strong electricity resistance and the ability to keep a transformer cool. Bio-based products are more fire resistant than others, thus expected to witness the highest growth till 2030. Since bio-based oils are fully non-toxic, which further facilitates disposal, they provide reliable and cleaner products. The demand for bio-based products is also anticipated to grow as a result of an increase in the installation of transformers occurring globally. Power utilities are also focusing on upgrading the safety and performance of both new and existing transformers, which is predicted to boost demand for bio-based products globally.

U.S. Transformer Oil Market size and growth rate, 2023 - 2030

Stringent regulation imposed by government bodies concerning energy wastage is expected to be the major challenge for product demand. For instance, the U.S. Environmental Protection Agency (EPA) has set up strict regulations on oil demand to control electricity wastage. Additionally, developed and developing economies are opting for green and environmental-friendly technologies, which are expected to restrain the growth of mineral-based products.

Market Dynamics

The power sector plays a major role in any nation's economic growth and contributes significantly to its GDP growth rate. The number of electricity generation plants and investments related to them primarily depend on the governments of respective countries. Various major countries shifting their focus to rural electrification is anticipated to provide impetus to the demand for distribution transformers, thereby leading to an increased consumption of transformer oil.

Political instability in oil-producing economies such as Iraq and Saudi Arabia in the Middle East has led to extreme fluctuations in crude oil prices. Countries such as Iraq, Libya, Nigeria, Iran, and Venezuela are witnessing social unrest, which has negatively impacted the industrial sector in these economies and affected their crude oil production greatly in the past few years. The average price of crude oil was USD 52.32 per barrel in 2015 and reached USD 100.08 per barrel in 2022 with a major slump of USD 41.69 per barrel witnessed in 2020 owing to trade restrictions imposed during the COVID-19 pandemic. Thus, fluctuating prices of crude oil are predicted to impact the cost of base oil, thereby resulting in volatile costs of transformer oil. This is anticipated to hamper the market growth.

Product Insights

Mineral-based oils dominated with a revenue share of over 75.6% in 2023. This is attributed to high compatibility and a wide range of applications of mineral-based oils in capacitors & circuit breakers. Mineral-based products are utilized in conditioning and shielding transformers, switchgear, and boilers. Additionally, it can be used for thermal transfer and to safeguard the interior field winding of transformers. Such wide usage of mineral-based oils is expected to drive growth from 2024 to 2030.

Bio-based products have recently gained significant demand. They perform better than other products as they are eco-friendly. Bio-based products use vegetable oil as a feedstock. This kind of oil does not contain halogens, silicone, and petroleum hydrocarbons. They are non-toxic and can quickly degrade in case of leakage or spill, which is expected to create growth opportunities for bio-based products.

Products produced from wax-free naphthenic mineral oil have various advantages such as low cost, easy availability, high efficiency, and thermal cooling capacity. However, non-biodegradability that results in environmental pollution and handling risks is projected to restrain demand for naphthenic-based mineral oil products from 2024 to 2030.

Rating Insights

The 100 MVA to 500 MVA segment dominated with a revenue share of over 53.8% in 2023. Application of such transformers in large-scale industrial settings, including refineries, power plants, and manufacturing facilities is expected to propel this growth. These transformers have been designed to handle large amounts of electrical power and have become vital components in the generation, transmission, and distribution of electrical power. Moreover, they can adequately distribute power in highly populated areas due to their capacity to handle high voltages, making them ideal for transferring power from source to desired destination.

The <100 MVA segment held the second-largest position in 2023 and is projected to grow at a CAGR of 12.0% from 2024 to 2030. This is attributed to its application in a variety of power distribution systems to step down or step up the voltage of electrical power, allowing it to be transmitted over long distances.

End-use Insights

The industrial segment dominated with a revenue share of over 48.8% in 2023. This is attributed to growing industrialization across the globe leading to an increased number of transformers. Industrial end-use includes transformers used in chemicals, food processing, steel, and automotive industries. Industrial processes require different types of electrical machinery that operate at discrete voltage levels. Power generation facilities typically generate electricity at high voltages, requiring the use of three-phase distribution transformers.

Thus, advancing steel and chemical manufacturing industries worldwide have increased demand for transformers used in them which in turn will drive the demand for transformer oils used for efficient functioning of these transformers.

Global Transformer Oil Market share and size, 2023

The residential segment is expected to grow at the highest CAGR of 12.7% from 2024 to 2030. This is attributed to growing residential areas owing to the increasing global population. The residential segment includes transformers used in villas, apartments, and residential housing. In residential spaces and villas, typically single-phase transformers are used for individual homes, and three-phase distribution transformers for larger residential areas.

Regional Insights

Asia Pacific dominated the transformer oil market with a revenue share of over 55.2% in 2023. This is attributed to a rise in demand for electricity in Australia and developing countries such as China, India, and Japan. Additionally, the growth of the commercial and industrial sectors is anticipated to increase the number of substations, which, in turn, will fuel transformers’ demand.

Increasing investments in the power sector are enabling market penetration of Chinese manufacturers. Moreover, significant growth in renewable capacity in countries such as India and China is fueling demand in the sub-transmission segment. The presence of strong domestic manufacturers is a major challenge for foreign markets entering the Asia Pacific region.

Transformer Oil Market Trends by Region, 2023 - 2030

Growth of industrial and manufacturing sectors in the U.S. and Canada is driving North America's market growth. Technical upgrades, modernization in existing transformers, and a declining crude oil market are anticipated to drive regional market expansion.

Key Companies & Market Share Insights

The market is moderately fragmented with key participants focusing on capacity and geographical expansions, as well as mergers & acquisitions, to expand their consumer base. These players are also focusing on R&D activities to formulate novel products to strengthen their market foothold. For instance, in May 2023 Cargill Inc. launched its FR3r natural ester, a new 100% biodegradable and environment-friendly transformer insulating fluid derived from more than 95% rapeseed oil. This new product launch will provide the company with a competitive edge.

Key players are focusing on bio-based oil production, along with various strategic initiatives, such as R&D activities, to develop eco-friendly oils and create innovative goods and solutions.
