Climate-neutral energy mix

To produce it's own energy, Sumitomo Drive Technology invests in a renewable energy mix.

The new photovoltaic system on the roof of the test hall consists of 222 modules that generate a production output of up to 10,000 kilowatt hours per month, depending on the prevailing weather conditions.

Sumitomo has also been producing its own electricity since 2015 with a natural gas-fired combined heat and power plant (CHP). Its waste heat is used for heating and hot water supply, further optimizing the energy balance of the CHP plant.

On average, the CHP produces about 30,000 kilowatt hours of electricity and 50,000 kilowatt hours of heat per month. With its photovoltaic system and combined heat and power plant, the transmission specialist currently covers almost 15 percent of its electricity requirements from its own generation.

Further photovoltaic systems are planned for next year, which should supply an additional 750,000 kilowatt hours of electricity per year. Considering the total annual consumption of 2.1 GW, this would already cover almost 50 percent of the company's own needs.
