Strengthening the profitability of the electricity business through energy management
The Virtual Power Plant (VPP) is a system that operates as if it were a power plant by connecting and controlling energy resources such as storage batteries that are dispersed throughout each region through a system, as opposed to conventional large-scale power plants.
The challenges with solar power and wind power generation are that the amount of power generated fluctuates with the weather and season, causing instability in the supply-demand balance, and that the control of power generation output is required when demand is low. To solve these problems, VPPs can be constructed to stabilize the supply-demand balance and maximize the use of renewable energy by using storage batteries to store electricity when there is a surplus and discharge electricity when there is a shortage, for example.
Business Policy
・Establish VPP systems and operation systems that collectively monitor and control resources such as storage batteries and EVs and expand VPP resources through the joint development of projects and management contracts
Main Initiatives
One of Japan’s largest grid-scale storage batteries
The Group’s main resource, the grid-scale storage battery, is the Muroran Storage Battery Plant, which began operations in March 2024 and is one of the largest in Japan at 50 MW. In addition to this, we are also constructing a new storage battery plant in Chiba. We will create value by utilizing these storage batteries in the electricity market. In the future, in addition to joint development with customers who plan to own grid-scale storage batteries and storage battery plant management contracts, we will also be actively engaged in on-site storage batteries for renewable energy sources.
Distributed Energy Resources
We are developing businesses that utilize energy resources such as demand facilities, electric vehicles (EVs), and storage batteries for household and corporate customers and aim to expand our services to promote the spread of various resources in the future.
As part of these efforts, we began a verification trial for storage battery control in the Urawa Misono district of Saitama Prefecture in May 2023. In addition, as announced in May 2024, we are also working on a verification trial utilizing EVs in the Kurashiki district of Okayama Prefecture.
