Miaoli Offshore Wind Power Project II passes EIA

The Miaoli Offshore Wind Power Project II offshore wind farm project off Houlong Township in Miaoli County is expected to use a "floating foundation" without piling, in the hope of reducing the impact of underwater noise on the ecology of the sea. The Environmental Protection Agency (EPA) held an environmental assessment meeting yesterday to review the project, requiring environmental monitoring of the sea substrate, intertidal water quality, cetaceans and birds before construction, and passing conditions such as environment-friendly construction and avoidance of fault zones.
Floating foundation without piling
The project developer, Hai-Shuo Power Company, reported that the "Miaoli II" wind farm is located off the coast of Houlong, Miaoli, with an area of about 157 square kilometers and a distance of 20 kilometers from the shore, and the submarine cable is expected to come ashore from Zhunan and Tongxiao, Miaoli. The wind farm has a capacity of 9.5 to 20 MW (kilowatt) per unit. The maximum installation capacity will not exceed 1,536 MW, with a maximum of 161 wind turbines. The construction method is expected to be a pile-less floating submerged foundation, which will be fixed to the offshore wind turbine foundation by means of tethers and anchors.
Environmental monitoring before construction
Some EIA members thought that although the case is expected to adopt a "floating foundation" without piling, the technology of floating wind turbines in Taiwan is not yet mature, and the development unit should still reserve the right to use a commercial negative pressure caisson foundation or a more environmentally friendly construction method after obtaining the approval of the Ministry of Economic Affairs. In addition, the detailed design should detect whether there are any faults in the wind farm, so that the location of the wind turbine can avoid the faults to avoid subsequent problems.
In terms of environmental monitoring, the Environmental Protection Commission requires that sea bottom quality monitoring, cetacean visual surveys and bird radar monitoring should be conducted prior to construction, and intertidal water quality monitoring should be carried out in the landing area of the submarine cable; the monitoring plan during operation should also include investigation items such as cable inspection and entanglement removal to avoid the danger of biological entanglement.
