Containerized Battery Energy Storage Systems (BESS) are essentially large batteries housed within storage containers. These systems are designed to store energy from renewable sources or the grid and release it when required.

Here's a simple breakdown: This estimation shows that while the battery itself is a significant cost, the other components collectively add up, making the total price tag substantial. As of recent data, the average cost of a BESS is approximately $400-$600 per kWh.

While BESS wholesale prices in Thailand average $420/kWh today, Chinese suppliers like CATL and BYD are slashing quotes to $310/kWh for 2025 deliveries. Compare that to Germany's $580/kWh – why overpay? But here's the catch: Thailand's BESS price per kWh varies wildly.

This Technical Brochure will provide a guide to how to implement BESS in a substation, both for existing and new substation projects. Integrating the BESS-connected substation to the power grid, it is necessary to understand the Grid codes.
