India’s plan to spend ₹9 lakh crore on grid expansion by 2032 is boosting demand for transformer oils. Savita Oil and Apar Industries are two major companies supplying this critical product. Investors should understand how these firms are positioned to grow, their reliance on raw material costs, and the risks associated with their current market valuations.
What Happened
India has embarked on an ambitious power infrastructure project, with an estimated ₹9 lakh crore planned for grid expansion by 2032. This program aims to strengthen the national transmission network to handle the surge in renewable energy capacity, which rose by 55.3 GW in FY26 alone. This massive physical expansion of power grids creates a steady demand for transformer oil, a specialized fluid used to cool and insulate electrical transformers. While it may seem like a niche product, it is essential for the functionality of power lines, railways, data centers, and renewable energy plants.
Business Context For Savita Oil
Savita Oil is a significant player in the specialty petroleum segment, with roughly 73% of its revenue coming from these products. The company manufactures its transformer oils under the 'TRANSOL' brand. For investors, a key point to note is the company's operational headroom. It is currently operating at 65-70% of its capacity, meaning it has room to increase production to meet rising demand without needing to spend heavily on new factories immediately. Furthermore, its diverse customer base, where no single client contributes more than 5% of its revenue, provides a layer of stability against order cancellations or individual client issues.
Business Context For Apar Industries
As a larger player, Apar Industries operates on a different scale, being the third-largest transformer oil manufacturer globally. The company markets its products under the 'POWEROIL' brand and has secured a niche position as the sole supplier of high-voltage direct current (HVDC) transformer oil to global majors like Hitachi Energy, GE, and Siemens. Apar uses an integrated business model, selling transformer oils alongside its conductors, which together make up a large portion of a transformer's core components. This integration can simplify the supply chain for its customers. With nearly half of its transformer oil revenue coming from international markets, the company is actively expanding its global footprint, including a new manufacturing site in Saudi Arabia.
Financial And Risk Reality
While the demand outlook for these companies is supported by national grid spending, investors should look beyond the top-line growth. Both companies are currently trading at higher valuations compared to their historical averages.
A critical risk for both firms is their dependency on base oil prices. Transformer oil is a derivative of crude oil. If crude oil prices rise sharply, the cost of raw materials increases, which can put pressure on profit margins if the companies cannot pass these costs on to their customers. Additionally, while Apar Industries has a strong global presence, this also exposes the company to risks such as currency fluctuations and international trade policies.
What Investors Should Track
For those following these companies, the most important monitorable is how they manage their profit margins during periods of raw material price volatility. In the coming quarters, investors may look for signs of consistent order execution and whether the demand from newer areas like data centers and battery storage is enough to offset any slowdown in traditional power projects. Finally, watching the utilization levels of the new capacities and the progress of international expansions will be key to understanding if these companies can continue their growth trajectory.
