Toward the Realization of a Sustainable Society Solar carport with 2MW power generation capacity installed

Hioki has decided to install a solar carport (carport-type solar power generation system) with a power generation capacity of 2MW and a 2MWh lithium-ion energy storage system in the employee parking lot on the south side of its headquarters site.
In February 2022, we formulated the "Basic Sustainability Policy" and the "Hioki Sustainability Declaration," which set targets for CO2 emissions in order to realize a sustainable society. The Hioki Sustainability Declaration calls for achieving Scope 1 and Scope 2 carbon neutrality by 2025 (the 90th anniversary of our founding) and Scope 3 carbon neutrality by 2035 (the 100th anniversary of our founding).
The 2MW solar carport and 2MWh lithium-ion energy storage facility that is to be installed on the 23,000m2 south parking lot will enable the company to supply about half of the electricity used at its headquarters in-house. In addition, four different types of solar power generation equipment will be installed to serve as a testing ground for the Company's business of electrical measurement. 
At the same time, we plan to proceed with experiments in energy management systems utilizing the IoT.
Construction will begin in 2023 and is expected to be completed by 2025.

  • *:Scope 3 is a policy to achieve carbon offsetting without relying on emissions trading as much as possible toward the target by 2035.
  • *:Scope 1: Direct greenhouse gas emissions by businesses themselves (fuel combustion, industrial processes)
    Scope 2: Indirect emissions associated with the use of electricity, heat, and steam supplied by other companies
    Scope 3: Indirect emissions other than Scope 1 and Scope 2 (emissions by other companies related to the business's activities)
