Hitachi Energy announces a $479-million investment to build a transformer insulation factory in London, Ontario, with support from the federal and Ontario governments. The company says the project is intended to strengthen capacity for transformer insulation materials.

According to outlets, the planned facility would cover about 21,000 square metres and is described as the first plant in Canada to produce pressboard, a paper-pulp-based material used to help keep transformers cool. Reporting links the investment to expectations that electricity demand will rise.

Across the sources, the emphasis is broadly consistent: the investment amount, the location in London, Ontario, the government participation, and the product focus on pressboard. Differences are mainly in how outlets characterize the size of the plant and the market context, but the core details of the plan remain the same.
