Message from the President

ENNET contributes to a sustainable society through new value from energy and ICT

For more than 20 years since its founding in July 2000, ENNET Corporation has supplied clean and stable electricity to customers across Japan, through proactive procurement of renewable energy from sources including liquefied natural gas (LNG) power generation as well as solar, hydroelectric, biomass, and wind power.

The company name ENNET expresses its concept of continuing to create new value utilizing energy and information and communications technology (ICT) networks to increase sustainability for people, society, and the planet.

As a result, in November 2021 we supplied electricity to more than 110,000 customers from Hokkaido to Okinawa.

To meet customers' increasingly diverse needs, in addition to offering value-added services such as the EnneGreen lineup of services that help reduce CO2 emissions from electricity and Enneteye AI-driven energy-conservation services, we plan to enhance our service lineup even further.

As we aim to remain the comprehensive energy services provider that continues to be chosen by our customers, we will contribute to a sustainable society by delivering valuable services while listening closely to feedback from customers and to the needs of society.
