Policymakers working on Japan’s offshore wind energy roadmap are mulling ideas for raising the number of offshore wind energy installations in the seas around Japan as far out as its exclusive economic zone. Their aim is to have up to 45GW of offshore generation capacity online by 2040. One thing they need to look into if Japan is to continuously develop more offshore capacity is how to lower the costs of wind power. Operation and maintenance (O&M) costs account for about one-third of the total, making them a prime candidate for reduction.
It is impractical to station personnel at turbines or to frequently visit them, increasing the risk of delays in getting them back up and running after something goes wrong. Large-scale repairs push O&M costs up even higher. Initiatives in Europe, where development of offshore wind is proceeding at a rapid clip, might provide hints for solutions.
