In the late 1980s, the China Light and Power company sought to build a new electricity generating plant in Hong Kong. Many sites were examined, including Gruff Head in Sai Kung, Fan Lau, and Black Point in Tuen Mun. After Gruff Head was rejected by the government in 1989, CLP proposed to build a coal-fired plant at Fan Lau. The plant would have covered an area of 60 hectares, and would have incorporated chimneys, ash lagoons, pylons, and new roads. This was fiercely opposed by major environmental groups in Hong Kong. In 1990, the Fan Lau site was rejected by the government for its "unprecedented level of conflict with the Country Parks Ordinance" and air pollution concerns. Instead, the Black Point Power Station, a gas-fired station, opened near the existing Castle Peak Power Station in 1996.
As with other coastal locations in the region, the coastlines of Fan Lau are marred by accumulation of marine refuse.
