The "Pumped Storage Plan" is a plan that returns the profits generated from the operation of pumped storage power plants to electricity bills. Shirokuma Electric operates pumped storage power plants. By creating reservoirs at different elevations, water is pumped up when electricity prices are low, and water is released to generate electricity and sell it when prices are high, thereby generating profits. Our company operates pumped storage power plants and has launched a plan to apply the profits to discount electricity bills. This significantly reduces the risk of rising electricity costs for corporate clients.

We would like to introduce a case study on the installation of a "solar carport" at the Caledonian Golf Club. In order to enhance the value for club users, we considered the idea of adding a roof to the parking lot and focused on solar carports, which can also increase environmental value. We introduced the "Shirokuma Carport" with the expectation of improving customer convenience and reducing electricity costs through self-consumption of the generated power. The Shirokuma Electric solar carport features a cantilever structure with support only at the rear, ensuring that the posts do not obstruct parking, and it has a maximum height of 3.6 meters, allowing for good visibility even for high-roof vehicles. 【Case Overview】 ■ Number of parking spaces: 64 ■ Installation location: Existing parking space ■ Total power generation: 258,617 kWh ■ Power self-sufficiency rate: 17.5% ■ CO2 reduction effect: 117.5 tons-CO2/year ■ Provision format: PPA method *For more details, please download the PDF or feel free to contact us.

The "Shirokuma Carport" is a carport equipped with solar panels that can reduce both electricity costs and CO2 emissions. If the electricity is generated in-house, there will be no electricity charges, fuel adjustment fees, FIT surcharges, or transmission fees. This leads to significant reductions in electricity costs and mitigates the risk of future price increases due to external factors. Additionally, having a roof over the parking area provides shade and protection from rain, enhancing convenience for users. Since solar power is 100% renewable energy, it serves as a strong appeal for decarbonization management. 【Three Benefits】 ■ Reduction in electricity costs ■ Increased convenience for users ■ Decarbonization appeal *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where a "solar carport" was installed in the staff parking lot of the Yachiyo Town Hall in Chiba Prefecture. Power supply through a Power Purchase Agreement (PPA) began on April 27, 2023. It is expected to reduce CO2 emissions by 58.4 tons annually as a renewable energy source with additionality. Additionally, it has become possible to implement the system in a short period using a unique construction method. 【Case Overview】 ■ Land Area: 746.16 m² ■ Installation Location: Existing parking space ■ Total Power Generation: 145,266 kWh/year ■ Self-Sufficiency Rate: 24.6% ■ CO2 Reduction Effect: 58.4 tons-CO2/year ■ Provision Method: PPA *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where one of Japan's largest "solar carports" was installed at Joyful Honda Chiba New Town store. The estimated annual power generation is 1,169,199 kWh, with an expected reduction of approximately 456 tons of CO2 emissions per year. By introducing the solar carport, we will supplement the environmental value that was insufficient with just rooftop installations, and together with the existing power generation facilities, we will increase the self-sufficiency rate of electricity to 20%. 【Case Overview】 ■ Number of parking spaces: 348 (including spaces for people with disabilities) ■ Installation location: Existing parking area ■ Total power generation: 1,169,199 kWh ■ Renewable energy ratio: 20% ■ CO2 reduction effect: 456 tons of CO2/year ■ Provision method: PPA (Power Purchase Agreement) *For more details, please download the PDF or feel free to contact us.

The reason you can introduce the "Shirokuma Carport" for 0 yen is that by signing a long-term power supply contract with Shirokuma Electric, you can procure green electricity generated by the newly installed solar carport at a fixed unit price. This allows for reductions in electricity costs and the avoidance of future price surge risks, stabilizing expenses. On the other hand, our company can cover the installation costs through revenue from electricity charges, making it possible for customers to have an initial cost of 0 yen. 【Case Studies】 ■ DCM Anesaki Store ■ Yachiyo Town Hall ■ Cainz Urawa Misono Store ■ Yorozu Oita *For more details, please download the PDF or feel free to contact us.
