Regional Resilience and Microgrid Applications
By integrating distributed generation, energy storage, and energy management systems (EMS), microgrids operate grid-connected or independently in island mode to enhance regional energy resilience, mitigate climate risks in remote areas, and lower offshore island generation costs. To aggregate distributed solar, wind, and storage into dispatchable grid assets, Taipower is evaluating microgrid integration with Virtual Power Plants (VPPs)—anchored by the Taiwan Power Research Institute’s Shulin verification site (launched October 2025) to test seamless grid switching and autonomous backup power.
Developing Disaster-Resilient Microgrids and Regional Grid Energy Storage Applications
Taipower targets disaster-prone, isolated areas by deploying self-sufficient smart microgrids (Green Energy + Energy Storage + Diesel Generation + EMS). Installed across remote locations—including Pingtung (Wutai, Mudan, Shizi), Chiayi (Alishan), and New Taipei City (Wulai)—these systems strengthen emergency power supply and community safety.
To broaden operational benefits, Taipower is scaling microgrid applications across two key domains:
- Regional Grid Energy Storage: Conducting energy storage and islanding verifications at five key sites (Chiayi's Xinwen, Yunlin's Yungang, Tainan's Nanhua, Kaohsiung's Meinong, and Pingtung's Xinwei) to boost daily regulation and disaster relief capabilities.
- Campus Microgrid Demonstrations: Establishing demonstration microgrids across three major universities (NTUST, NCHU, and CCU), with validation testing targeted for completion in 2026 to serve as blueprints for wider deployment.

Offshore Island Microgrids and Strengthening Offshore Island Power Supply
To address power reliability challenges on isolated offshore islands, Taipower deploys microgrids combining renewables, battery storage, and smart technologies, while utilizing the Taiwan-Penghu Submarine Cable to stabilize local supply and wheel excess clean energy back to the mainland grid. Concurrently, long-term power source development across Kinmen, Matsu, and Penghu continues to expand renewable integration capacity, forging a more resilient offshore power infrastructure.
Regional Grid Energy Storage and System Regulation
To mitigate renewable energy intermittency, Taipower builds energy storage systems that stabilize grid frequency and boost dispatch flexibility. Leveraging the Electricity Trading Platform (launched 2021) and E-dReg technology (introduced 2022), Taipower reached 160 MW in self-built battery energy storage capacity by 2025—headlined by major installations at Tainan Salt Field (20 MW), Luyuan (20 MW), Longtan (60 MW), and Dongshan (60 MW). Additionally, system testing for five substations constructed in 2024 began in 2025, with final testing across the remaining three substations targeted for 2026 to unlock over 2 MW of generation capacity and 4 MW of storage capacity.
Generation Forecasting, Dispatch Integration, and Real-Time Stability Control
As the proportion of renewable energy connected to the grid increases, power dispatch requires stronger real-time monitoring, generation forecasting, and unit adjustment capabilities. Taipower continues to strengthen renewable energy forecasting, dispatch integration, and power plant operation and maintenance management to enhance system stability and power supply reliability.
Taipower integrates weather forecast data from the Central Weather Administration and private weather companies every day, and combines tools such as the Supervisory Control and Data Acquisition system (SCADA), the Distributed Renewable Energy Advanced Management System (DREAMS), the Solar Power Generation Real-Time Estimation System (GEMS), and energy management systems (EMS) to provide real-time dispatch information to the Central Dispatch Center. This enables flexible adjustment of conventional unit output, as well as unit startup and shutdown schedules.
The main measures are as follows:
Strengthening generation forecasting |
Incorporating private-sector ancillary service resources |
Optimizing unit dispatch |
|
Taipower references weather data and uses GEMS to improve forecast accuracy. |
Taipower integrates private energy storage and distributed resources through the Electricity Trading Platform. |
Taipower adjusts thermal power, pumped- storage hydropower, and hydropower generation schedules based on green energy output conditions to improve dispatch flexibility. |
Renewable Energy Power Plant Operation and Maintenance Efficiency
To enhance the generation efficiency and equipment availability of renewable energy power plants, Taipower continues to strengthen preventive maintenance and regular inspections to reduce failure rates, while selecting materials and components with low-carbon footprints to reduce environmental impacts.
Wind power
Taipower continues to refine its wind power forecasting system and strengthens major component maintenance management capabilities through wind turbine big data analysis, health status tracking, fault precursor diagnosis, and maintenance schedule optimization.
Solar power
Taipower continues to review the appropriateness of nighttime electricity consumption at sites to avoid unnecessary energy use and increase overall power generation.
