Optimal renewable energy procurement
Based on the know-how of electric power business operation built up over 30 years and on the strength of stable demand from condominiums owned by the company's customers, the company provides services that achieve both "decarbonization" and "cost reduction" for small, medium and large companies and municipalities throughout Japan.
In the electricity it supplies, the company is increasing the ratio of renewable energy, including real energy, and promoting carbon-free energy, thereby contributing to the realization of a decarbonized society. In addition, we issue J-credits from our own solar power plants to promote decarbonization.
To manage unstable renewable energy, the company will use technology to optimize procurement and adjust supply and demand.
The distribution of electricity supplied to our customers by power source is detailed below:
(*1) Part of the cost of procuring this electricity is covered by a levy collected from all electricity users, including those who are not our customers, and the use of non-fossil certificates is required under the national system to promote the value of renewable energy, including the fact that it emits no CO2. The FIT electricity sold by our company is covered by a certificate of non-fossil energy. The FIT electricity we sell is treated as electricity with the national average CO2 emissions, including thermal power generation.
(*2) Electricity procured from the Japan Electric Power Exchange (JEPX) includes hydroelectric, thermal, nuclear, FIT electricity, and renewable energy.
(*3) Electricity supplied by general transmission and distribution companies on an imbalance basis is treated as "Other.
Electricity procured from other companies whose power plants cannot be identified is sorted based on the power source composition information regarding electricity supplied to us from each supplier or the power source composition for the most recent fiscal year announced by each supplier (FY2024 or FY2023).
Due to rounding, the total may not equal 100%.
The CO2 emission factor (adjusted emission factor) for our company as a whole for FY2024 is 0.162 kg-CO2/kWh (estimate).
(*4) We sell environmental menu using non-fossil certificates to some of our customers, and the above percentages include 380,955 thousand kWh of electricity sold using non-fossil certificates out of 437,930 thousand kWh of total electricity sold. (Actual figures for FY2024)
| menu | Provisioning method (power supply sources, etc.) | Emission factor (kg-CO2/kWh) | Ministry of the Environment Menu notation in (*5) |
| Normal Menu | Supplied by natural gas, etc. | 0.422 | Menu D (residual) |
| Carbon Free Menu | Power supply is the same as the normal menu FIT non-fossil certificates provide electricity with virtually zero CO2 emissions. |
0.000 | Menu A |
| Renewable Energy Menu | Power supply is the same as the normal menu FIT non-fossil certificates provide electricity that is considered substantially renewable energy and has virtually zero CO2 emissions. |
0.000 | Menu B |
| Renewable Energy RE100 Menu | Power supply is the same as the normal menu FIT non-fossil certificates with tracking provide electricity that is considered substantially renewable energy, has virtually zero CO2 emissions, and meets RE100 eligibility requirements. |
