Grid Storage Battery
Grid Storage Battery
Grid-connected batteries contribute to the realization of a carbon-neutral society
It is said that greenhouse gas emissions into the atmosphere need to be reduced to virtually zero worldwide by 2050. Because the use of storage batteries allows for efficient use of generated electricity, many local governments are providing support to businesses using them through special energy measures accounts and other means.
1. What is a grid storage battery?
A grid battery is a storage battery that is directly connected to the power grid (a collective term for power plants, substations, transmission lines, and distribution facilities), which is the system that creates and delivers electricity. Because it is connected to the grid, it is possible to sell purchased, generated, and stored electricity on the market, and it can also be used as a medium- to long-term investment, which is why it has attracted attention both in Japan and overseas.
2. Grid-connected batteries, when combined with solar panels, are effective in saving energy and being eco-friendly for businesses.
In recent years, while the price of selling electricity has been declining, electricity bills have been rising, and the cost benefits of using electricity for self-consumption are greater than the benefits of selling electricity. Since power generation by solar panels is dependent on the weather, storing electricity in a large storage battery allows for more efficient use of the generated electricity.
3. There are various types of solar panels to choose from depending on the installation location.
-
・Installed on the roof
It can be placed on the roof of a house.
-
・Installed on the roof
It can be installed using rooftop space of factories, buildings, etc.
-
・Installed on site
It can be installed over a wide area and generate large amounts of power.
4. Grid storage helps companies reduce costs

1) By using stored electricity when not generating electricity, electricity can be used efficiently.
A grid battery is a storage battery that is directly connected to the power grid (a collective term for power plants, substations, transmission lines, and distribution facilities), which is the system that creates and delivers electricity. Because it is connected to the grid, it is possible to sell purchased, generated, and stored electricity on the market, and it can also be used as a medium- to long-term investment, which is why it has attracted attention both in Japan and overseas.

2) Surplus electricity can be sold to new power companies
With the liberalization of the electricity market, it is now possible to sell electricity to new power companies (retail electricity suppliers and specified-scale electricity suppliers). By selling surplus electricity from your own consumption to new power companies, you can expect to cut costs more efficiently.
5. The introduction of industrial storage batteries may be eligible for subsidies
The introduction of large-capacity industrial storage batteries allows electricity generated by renewable energy to be stored and used during times of high demand, so they may be eligible for subsidies to promote regional decarbonization under the Special Account for Energy Measures promoted by the Ministry of the Environment. Subsidy eligibility varies by local government, so it is necessary to check with each local government.
*The introduction of large-capacity industrial storage batteries can contribute to reducing emissions of CO2 and other substances through the use of renewable energy, and may therefore be eligible for participation in the J-Credit Scheme in the future.
The appropriate system for industrial storage batteries varies depending on the amount of electricity normally used by a company, the installation space, etc. Please contact us regarding eligibility for subsidies, etc.
