US offshore wind market emerging

Installed offshore wind capacity in US waters could reach 20 gigawatts (GW) by 2030 and annual investments in the sector could surpass US$15 billion by the mid-2020s, according to new research by Rystad Energy.

Such a trajectory means capex in US offshore wind will likely exceed those in US offshore oil and gas within the next five years.

“There are currently 6 GW of offshore wind projects in the US which have been sanctioned for development, requiring collective investments of more than US$20 billion over the next five years.

“Assuming continued support from the regulators, many more projects will be sanctioned in the coming years and we expect to see yearly investments in the sector exceed US$15 billion by the middle of the decade,” said Tim Bjerkelund, Head of Consulting New York at Rystad Energy.

“That would certainly signal an energy revolution and offshore suppliers should take note.”

By comparison, the analyst expects annual expenditure on US offshore oil and gas projects to average US$14.8 billion between 2020 and 2025.

The US North-east has for decades been dependent on importing energy, either from other states or from other countries. Renewable energy could offer a remedy, but wind and solar projects are typically land-intensive, which poses problems in areas of high population density such as the US North-east.

“This is reminiscent of problems faced by European countries, and the states in the North-east have wisely picked up the same playbook. Benefiting from the technological developments and cost efficiencies introduced in the North Sea, these states are adopting the lessons learned and are rapidly rolling out targets for a much higher share of renewables in their power mix,” Mr Bjerkelund said.

Projects such as Vineyard Wind are expected to see costs close to the levels of European projects. This bodes well for an industry that is still in its infancy.

According to the Energy Information Administration, the potential for offshore wind in the US is 7,200 TWh. If all of this were to be realized, it would equal hundreds of projects similar to the ones already sanctioned, with each requiring investments of around US$3 billion on average, according to Rystad.

“The emergence of offshore wind as an industry in the US is truly exciting. The energy transition is taking place now – not through small test projects, but through utility scale projects that each require billions of dollars in investment.

“US suppliers should take note – this new industry could outgrow offshore oil and gas in only a few years’ time, providing lots of new opportunities,” Mr Bjerkelund concluded.
