Mailiao Plant Coal-Fired Generators to Resume

Why It Matters

The decision underscores Taiwan’s reliance on coal as a contingency against geopolitical LNG disruptions, highlighting a trade‑off between energy security and emissions goals.

Key Takeaways

• Taipower reactivates two 500 MW coal units for three months.
• LNG risk stems from Middle East attacks on Qatar facilities.
• Regional peers also expanding coal to mitigate LNG volatility.
• Activation adds minimal increase to Taiwan’s annual coal use.
• Decision reflects energy security priority over short‑term emissions concerns.

Pulse Analysis

Taiwan’s power grid has leaned heavily on imported liquefied natural gas, which supplies roughly two‑thirds of its generation mix. Recent attacks on Qatar’s LNG facilities—accounting for about a third of Taiwan’s LNG imports—have amplified concerns about supply continuity, prompting the state‑run utility to seek immediate alternatives. By re‑commissioning the Mailiao coal generators, Taipower adds 1 GW of dispatchable capacity, providing a buffer against potential shortfalls while the global LNG market stabilises.

The short‑term coal restart mirrors a broader regional pattern where nations such as Japan, South Korea, Thailand and the Philippines have temporarily lifted coal output limits to hedge against volatile fuel markets. While coal offers reliable baseload power, its reintroduction raises questions about Taiwan’s carbon reduction commitments under its 2050 net‑zero target. Policymakers must balance the urgency of preventing blackouts with the longer‑term imperative to phase out fossil fuels, possibly by accelerating renewable integration and storage solutions.

Looking ahead, Taiwan may explore diversified energy strategies, including expanding offshore wind, scaling battery storage, and securing more resilient LNG contracts with diversified sources. The three‑month coal window provides a stop‑gap, but the island’s energy security roadmap will likely emphasise flexible, low‑carbon resources to mitigate future geopolitical shocks. Continuous monitoring of global LNG supply dynamics and domestic demand will shape whether coal remains a temporary crutch or a catalyst for broader reforms.
