Chubu Electric Power Group Report 2021(Integrated Report)

Chubu Electric Power Grid Co., Inc.Customer cooperation in the adjustment of electric power using distributed energy resources (DER) including solar power generation, storage batteries, and electric vehicles will aid reasonable facility formation and operation. Our goal is to build infrastructure and a system capable of achieving this. Specically, we are establishing a customer cooperation framework and connections with a DER control system to work as an aggregator controlling the DER owned by customers, and building a demand area distribution operation system capable of predicting regional power ow using our power ow/voltage information and weather information.

For bulk transmission systems that require a long time to construct equipment, we will reduce capital investment and steadily accept renewable energy with an eye toward the future by promoting well-balanced facilities formation.Demand Area Distribution SystemBuilding and operating facilities based on advanced technologyWe aim for rational formation and operation of facilities on a region-by-region basis utilizing advanced technology including ICT and IoT and sophisticating demand area distribution systems in responding to the increasing complexity of the ow of electricity arising from the large-scale introduction of renewable energy and the popularization of electric vehicles. Achieving this will enable us to coordinate renewable energy sources quickly and rationally to contribute to the realization of a carbon-free society.Consideration for demand area systemMain InitiativesExamples of main initiatives44Chubu Electric Power Group Report 2021Top CommitmentValue CreationClimate ChangeStrategyBusiness ActivitiesGovernanceHuman ResourcesFinancial / Corporate Data
