UK-based grid resilience company Reactive Technologies Limited has launched its grid stability measurement service with The Taiwan Power Company (TPC), a state-owned electric utility providing electricity to more than 13 million industrial, commercial, and residential customers in Taiwan.

Reactive is ramping up the global rollout of its GridMetrix platform, first-of-its-kind software that offers real-time insight into the stability of a power system, enabling grid operators to reduce costs and manage risks more effectively.

Taiwan has set an ambitious “20-30-50” goal to have 20% of electricity generated by renewables, 30% by coal, and 50% by gas in 2025. With abundant wind resources, Taiwan is targeting 45-50 GW of offshore wind capacity by 2050. The country recently inaugurated the Formosa 2 offshore wind farm at the Waipu Fishing Port in Miaoli, one of the largest offshore wind farms in Taiwan.

TPC is responsible for the effective operation, coordination, and stability of the electricity grid in Taiwan. In this role, TPC has identified the significant and increasing risk of low grid inertia, a result of the decommissioning of fossil fuel power stations and significant increases in renewable generation.

Traditionally, fossil fuel power stations ensured Taiwan’s grid stability with inherent inertia, but as renewables like wind and solar grow, Reactive’s technology is vital to managing non-synchronous resources lacking inertia, preventing potential system instability and supply disruptions. With plans to retire coal-fired power plants in favor of renewables, TPC recognised the need for effective direct measurement, forecasting, and control of system inertia.

To achieve that capability, TPC has contracted Reactive Technologies’ GridMetrix inertia measurement service, which will enable it to accurately measure, visualise, forecast, and better control inertia across its network and provide critical system stability data and insights as the network goes through a period of significant change. The project will utilise a 60MW/96MWh DongShan battery energy storage system (BESS) currently under construction in the north of Taiwan, which will provide a modulation signal to be detected by Reactive’s measurement devices.

Reactive co-founder and CEO Marc Borrett said, “There is a pressing need to transition to secure, zero carbon grids, and our customers across the globe are asking us to help them deliver this at pace. The challenges facing TPC in their transition to clean energy are familiar to many other grids across the world. TPC have rightly identified the need for new tools to provide real-time accurate inertia measurement as a crucial component of their renewable energy transition and we look forward to supporting them at every step of their journey to net zero.”
