Taipower Inaugurated the 60 MW Longtan Energy Storage System to Enhance Grid Resilience

Taipower has constructed the Longtan Energy Storage System to enhance grid resilience, tripling the existing capacity to 60MW. Transforming the substation into an energy storage hub, the "Grid Empowerment, Resilience Forever" ceremony was held today. Taipower highlights the system's ability for rapid charge and discharge, aiding the integration of renewable energy into the grid's frequency regulation. It can also seamlessly collaborate with existing units, immediately providing stable power during unforeseen events and enhancing power system stability and flexibility.

Taipower collaborated with a major mobile and electric company, TECO, and an energy storage integrator, Fluence, forming an international team and installing 25 40-foot storage containers at the Longtan Ultra-High Voltage Substation, utilizing over 10,000 lithium battery modules along with transformers and power regulation systems. The result is a 60MW/80MWh energy storage system with a maximum supply power of 60MW and a total storage capacity of up to 80,000 kWh, equivalent to meeting the daily electricity needs of approximately 8,000 households.

Longtan Energy Storage routinely adjusts the grid system frequency, enhancing power supply stability. In emergencies, existing hydroelectric units can start within 10 minutes, while the storage system can provide immediate rescue in just 0.4 seconds.

Taipower further emphasizes that Longtan Energy Storage has achieved dual certifications for international energy storage standards are IEC 62933 and IEC 62443-3-3. Rigorous checks are in place for energy storage establishment, operation maintenance, and information security. With over 600 smoke, temperature, and gas sensors installed in the storage containers, the facility is under 24-hour surveillance, ensuring stable system operation. In case of emergencies, the gas fire extinguishing system inside the storage containers, along with the external mist firefighting system connected to a 50-ton water tank, works in tandem to swiftly address any issues.

Taipower has utilized its substations as energy storage development bases In recent years, successively creating Luyuan Energy Storage and Longtan Energy Storage. Taipower plans to complete the Dongshan Extra High Voltage Substation 60MW energy storage this year. In alignment with the government's goal of 1500MW overall energy storage by 2025, Taipower not only builds its energy storage but also integrates private resources through the power trading platform, aiming for 1000MW. Another 500MW will come from private entities combined with photovoltaic setups.
