HEXA Energy Services G.K. (Head Office: Chiyoda-ku, Tokyo; Executive Managers: Yuko Shah and Yoichiro Mizuta; “HEXA” or the “Company”) is pleased to announce that its group company, HEXA Renewables Japan Co., Ltd. (Head Office: Chiyoda-ku, Tokyo; President and Representative Director: Chenhua Shen; “HEXA Renewables Japan”), entered into a virtual power purchase agreement (“Virtual PPA”) with Dentsu Group Inc.

A Virtual PPA is an agreement under which a company purchases the environmental value generated by renewable energy facilities over the long term. This enables companies to expand their use of renewable energy while supporting the development of new generation facilities.

Through investments in Japan’s energy infrastructure, HEXA develops renewable energy and grid-scale battery energy storage businesses. HEXA Renewables Japan provides electricity and environmental value tailored to the decarbonization needs of corporate customers.

The Virtual PPA covers newly developed generation facilities and therefore provides additionality by supporting the deployment of new renewable energy capacity. HEXA Renewables Japan expects to supply approximately 1 million kWh of environmental value annually. The environmental value under the Virtual PPA is expected to be supplied to Dentsu Group locations in Japan.
