The research and consultancy firm forecast annual capacity is more likely to increase by 30 gigawatts (GW) a year by 2030, well below the 80 GW per year target, or five-fold growth, set by governments across the world.
“The supply chain is struggling to scale up and will be an impediment to achieving decarbonisation targets if change does not happen,” said Chris Seiple, vice chair, power and renewables at Wood Mackenzie.
“Nearly 80 GW of annual installations to meet all government targets is not realistic, even achieving our forecasted 30 GW in additions will prove unrealistic if there isn’t immediate investment in the supply chain,” Seiple said.
It would require $27 billion of new investment in the supply chain by 2026 and $100 billion of investment by 2030 for the sector to be able to meet government targets for five-fold growth in annual installations by the end of the decade, the report said.
Wood Mackenzie noted that the low profit margins on offshore wind production and uncertainty about project timings resulting in very different supply-chain needs are making it hard to drum up investment in the sector.
According to the Statistical Review of World Energy report in June, global wind and solar power grew to a record share of 12% of power generation last year, surpassing nuclear.
Target setting and plans for power market infrastructure to support offshore wind need to extend beyond 2030 to scale up the offshore wind supply chain, analysts at Wood Mackenzie said.
