Hitachi Energy is installing 2,414 solar panels on the roof of the up-building transformer factory at the Hitachi Energy Park in Vaasa region, Finland. The one megawatt-peak (MWp) solar power plant demonstrates the company's commitment to carbon neutrality and a sustainable energy future.
Hitachi Energy Park is a 170 million-euro investment, a transformer production and energy technology center spanning over 40,000 sq m. in the Vaasa region, in Vikby, Mustasaari. When completed in 2027, the facility will double Hitachi Energy’s transformer production capacity in Finland and expand the product range to include larger transformers, supporting the clean energy transition, electrification, and Finland's security of electricity supply. As part of the growth, Hitachi Energy will recruit approximately 200 new employees in the Vaasa region.
The solar power plant will produce 1.19 gigawatt-hours (GWh) of electricity annually, which is equivalent to the annual electricity consumption of approximately 66 electrically heated Finnish detached houses.1 The electricity generated by the panels will cover approximately 10 percent of the annual electricity usage at the Hitachi Energy Park, reducing the production’s carbon footprint by approximately 135 tonnes of carbon dioxide per year.
Our new Hitachi Energy Park, the transformer production and energy technology center, represents a very significant contribution to the clean energy transition. We develop and produce technologies and solutions that accelerate electrification and help build a carbon-neutral energy future. We are committed to responsible energy use in our own operations. We will utilize the latest energy efficiency solutions to reduce environmental impact and minimize energy costs. The solar power plant feeding energy into our operations is a great example of this.
All the electricity used by Hitachi Energy in Finland is generated from renewable energy. The heating solution for the new Hitachi Energy Park production and technology center will be based on geothermal heat pumps, and the waste heat generated in transformer production will be recovered and reused. The electricity produced by the solar power plant, as well as all energy use and the power grid of the facility, are monitored and controlled using Hitachi Energy's MicroSCADA system. This system ensures real-time equipment control, maintaining grid reliability and security under all conditions.
Sustainability is embedded in our global business strategy and we are committed to implement our targets of reducing our own impacts such as operational carbon emissions and waste while working with our value stream partners toward the same end.
Hitachi Energy in Finland has committed to the Energy Efficiency Agreement for Businesses, aiming to achieve a 10 percent energy savings by 2035. As part of the 2020–2025 energy efficiency program, the company exceeded its energy-saving targets by almost double. EcoVadis, the world's leading corporate sustainability rating agency, has awarded Hitachi Energy the highest platinum level in sustainability. The platinum rating is awarded globally to the top 1 percent of more than 150,000 companies rated by EcoVadis. Hitachi Energy's goal is to achieve carbon neutrality at all its own sites by 2030 and throughout its supply chain by 2050.
The solar power plant on the roof of the Hitachi Energy Park transformer factory is supplied by Solnet, a company that provides future-proof solar PV and battery energy storage solutions (BESS) across Europe with offices in the Netherlands, Germany, and Finland.
