Establishing a Certification System for the Field Project of Outdoor Battery Energy Storage System

Taiwan actively promotes energy transformation and net zero emissions. Generating 15.1% of energy using renewable sources by 2025 and reducing net zero emissions by 2050 is a goal set by Taiwan. Solar, Wind, and other renewable energy sources will be built on a large scale. The intermittent supply features of renewable energy will affect the traditional power grid. An energy storage system is a key technology to reduce the influence of intermittent renewable energy on the power grid, it can solve the problem of integrating renewable energy with the power grid on a large scale. Currently, the technological development of energy storage systems shows a diverse trend. In Taiwan, an energy storage system with a lithium battery is the first choice for most enterprises. Therefore, a certification system for outdoor battery energy storage system field project is proposed in this research for the outdoor grid-integrated energy storage system. This certification system adopts a three-stage certification method, including a design review before construction, field certification after completion, and regular test every two years. It guarantees the safety of the energy storage system and its related equipment. It facilitates the energy storage system industry's development and renewable energy policies.
