Feasibility Study and Cost Estimation of Transformer Oil Manufacturing Plant: A Cost Model Approach

Transformer oil, sometimes referred to as insulating oil, is essential to electrical transformer operation. Its main functions are to cool and insulate the internal parts. By acting as a dielectric medium, the oil prolongs the transformer's lifespan and improves overall performance by preventing electrical discharges between various components. It moves around inside the transformer, assisting in the dissipation of heat produced during the conversion of energy. Although there are synthetic and bio-based substitutes, refined mineral oil is usually the source of it. Moisture, impurities, or the disintegration of the oil's chemical structure can all cause its quality to decline over time. It must be tested and maintained on a regular basis to stay effective. According to an IMARC study, the global transformer oil market size reached USD 2.7 Billion in 2024. Looking ahead, the market is expected to grow at a CAGR of approximately 5.9% from 2025 to 2033, reaching a projected value of USD 4.4 Billion by 2033. The global market is primarily driven by the introduction of stronger environmental standards. Conventional mineral-based oils are coming under more scrutiny because of this trend towards cleaner, more environmentally friendly options. The market is therefore being positively impacted by the increase in demand for synthetic and bio-based oils, which are less detrimental to the environment and provide superior performance metrics. In addition, the market is benefiting from the global trend towards renewable energy sources including hydroelectric, solar, and wind. Transformers are frequently needed for these renewable energy projects to convert and send electricity to the grid. The oil used has a significant impact on these transformers' performance and quality. Additionally, the market is being greatly supported by the growing demand for the product for both new installations and maintenance. In addition, the demand for high-quality oil is being driven by the need for transformers that are more compact and efficient, which is being influenced by electric vehicles (EVs) in particular.

Case Study on Cost Model of Transformer Oil Manufacturing Plant

Objective: One of our clients has approached us to conduct a feasibility study for establishing a mid to large-scale transformer oil manufacturing plant in Nigeria. We have developed a detailed financial model for the plant's setup and operations. The proposed facility is designed with an annual production capacity of 50,000 kilo litre of transformer oil and will cover a land area of 6,000 square meters.

Manufacturing Process: The production of transformer oil involves multiple steps to ensure its purity, stability, and performance for electrical insulation. The base oil is first heated to the proper temperature to decrease viscosity and improve processing effectiveness. To increase dielectric strength, degassing is the next step, which involves removing volatile contaminants and dissolved gases. The next step is additive blending, which combines anti-corrosion chemicals and oxidation inhibitors to improve longevity and performance. After that, the oil is filtered to get rid of solid impurities and dehydrated to get rid of moisture, which guarantees that it has strong electrical insulation qualities. Any leftover gases are eliminated in a second vacuum degassing cycle, which increases dielectric strength even more. The oil is put through quality control testing prior to final processing to confirm characteristics such chemical composition, viscosity, and dielectric strength. After approval, the oil is filtered one last time to remove any remaining contaminants. After that, it is prepared for distribution to utility companies and transformer makers and packed in containers to preserve purity.

Mass Balance and Raw Material Required: The primary raw materials utilized in the transformer oil manufacturing plant include base oil (Naphthenic), viscosity improver, antioxidants, dispersant additives, detergent additives, anti-wear additives, friction modifiers, pour point depressant, foam inhibitors and corrosion inhibitors. To produce 1 kilo litre of transformer oil, we require 0.98 kilo litre of base oil (Naphthenic), 0.005 kilo litre of viscosity improver, 0.002 kilo litre of antioxidants, 0.002 kilo litre of dispersant additives, 0.002 kilo litre of detergent additives, 0.001 kilo litre of anti-wear additives, 0.0005 kilo litre of friction modifiers, 0.001 kilo litre of pour point depressant, 0.001 kilo litre of foam inhibitors and 0.001 kilo litre of corrosion inhibitors.
