Self-Delivery System Operation Case: Toyokuni Oil Co., Ltd. Successfully covered daytime electricity with 100% renewable energy using a self-delivery system with a scale of 1100 kWh.

Efforts are being made around the world to achieve a society powered by 100% renewable energy. However, what specific measures are necessary for factories to achieve a self-consumption rate of 100%? The first thing that comes to mind is utilizing storage batteries to store electricity generated from solar power and then using that electricity. However, determining how much electricity needs to be stored and how to adjust for fluctuations in solar power generation due to weather is a very complex issue. Even if a large number of storage batteries are installed, there may be times when there is excess electricity, and conversely, if there are too few storage batteries, it will not be possible to achieve a self-consumption rate of 100%. As a result, there may be a need to purchase electricity despite incurring costs. Our company has over a year of experience in addressing these challenges and, based on reliable simulations, we propose solar power and storage battery systems that are optimal for our customers' needs.
