The cumulative capacity of global offshore wind (OSW) has grown at a dramatic rate in recent years, increasing by 25-40% annually since 2011. Due to increasing industry maturity and the development of a specialized supply chain to support the industry, realization of economies of scale, and other factors, the levelized cost of energy from OSW has decreased significantly, which is an encouraging sign for development of this industry in North America.
This report illustrates how European OSW projects have realized dramatic cost reductions, and how the emerging US OSW industry can benefit from this experience. The European OSW industry started over twenty years ago, and currently has over 12,000 MW in commercial operation, while the US only installed its first 30 MW project late last year. With an installed fleet of 3,589 OSW turbines and larger turbines being offered by OSW turbine manufacturers, European projects are offering prices, before consideration of transmission costs, that are competitive with forecast wholesale market prices, promising a market that is sustainable and not dependent on government policy support.
