The green transformer market would be subject to high growth from 2025 to 2035 due to mounting environmental pressures, regulatory pressures, and the need for power transmission and distribution efficiency. The market would be approximately USD 17,752 million in 2025 and would be expanding at a growth rate that would reach USD 32,332 million in 2035 at a compound annual growth rate (CAGR) of 6.2% during the timeframe.
There are various drivers behind this market trend. One of the prime movers is the world's demand for clean energy, which is fuelling the need for energy loss and environmentally friendly insulation materials for lower transformers. Lower carbon emissions are also persuading them to move to lower transformers with biodegradable insulation fluids such as natural esters.
For instance, in smart grid uses, green transformers enable maximum efficiency with zero greenhouse gas emissions. There are challenges, however, in terms of high upfront cost and wholesale retrofitting of older infrastructure. To address these challenges, industries are making investments in technology that is higher in energy efficiency, lower in maintenance, and long-term sustainable.
