中威大安

Zhongwei Da'an Wind Farm is located on the coast of Da'an District, Taichung City, an onshore wind project supplying renewable power to the central grid.

Da'an Wind Farm is developed and owned by the private wind operator Chung Wei, not Taipower itself, located around Yong'an in Taichung's Da'an District. It was built in three phases starting in 2008, with the final phase completed in 2016, making it one of Taiwan's few onshore private wind farms to have gone through repeated staged expansions over more than a decade of operation.

中威大安 (Wind) currently reports a net generation of 49.3 MW across 1 unit(s), against an installed capacity of 75.9 MW (65% utilization).

Wind has no fuel cost and zero direct emissions, but output fluctuates heavily with wind speed and is less predictable than thermal generation. Generation is markedly seasonal — the Taiwan Strait's strong northeast monsoon in autumn and winter typically produces much higher output than summer. Onshore turbines cluster along the western coastline, while offshore wind farms concentrate off Changhua and Miaoli.

The Taiwan Strait is internationally regarded as one of the world's best offshore wind resource areas, and government-led offshore wind zonal development since 2018 has driven wind's share of generation steadily upward. Wind and solar are the two pillars of Taiwan's renewable expansion, but their intermittency also increases the grid's need for flexible backup such as storage and gas-fired capacity.
