Current information of offshore wind turbine tasks in New England waters exhibits that there’s renewed curiosity on this water-bound supply of wind energy.

Though the US has been slower to undertake offshore wind vitality — the European and Asian markets already boast greater than 10,000 offshore wind generators — it’s encouraging to notice the graduation of three offshore wind tasks, as these initiatives signify significant strides towards reaching a sustainable and clear future.
Why the expansion of offshore wind?
The benefits of offshore wind energy, in comparison with land-based tasks, have gotten extra compelling. A few of the causes are:
- The wind useful resource is commonly stronger and extra dependable than on land, and tiny variations within the wind useful resource can imply a giant distinction in a turbine’s producing effectiveness.
- Much less potential for impacts on avian species and different wildlife in sure geographies, so there could also be fewer regulatory hurdles.
- Sound and visible implications of offshore wind tasks are fewer, so there could also be fewer stakeholder relations points.
- Much less threat that topographical options will disrupt the wind useful resource.
- Fewer restrictions on top of towers and size of blades.
And more and more, offshore wind will not be confined to shallow waters. Floating wind is changing into extra sensible, with installations within the North Sea and different elements of the world in search of even stronger and extra dependable winds additional offshore. Assurance and threat administration consultancy DNV says that floating offshore wind capability is projected to succeed in nearly 270 GW by 2050, as per its 2023 Power Transition Outlook analysis.
We’re now seeing larger curiosity in offshore wind mixed with different types of renewable vitality akin to solar energy arrays. There’s additionally curiosity in offshore wind getting used to generate hydrogen gas from seawater, with the fuel pipelined to shore. There’s discuss of utilizing offshore wind generators to seize carbon dioxide from the ambiance and sequester it deep into appropriate rock formations.

Transmission points
Throughout my 14 years on the Bureau of Ocean Power Administration (BOEM), I might see that one of many greatest challenges dealing with the event of offshore wind needed to do with transmitting the facility to shore. A lot of this has to do with placing a steadiness between bringing this clear, renewable vitality to prospects whereas additionally defending the aquatic atmosphere from dangers introduced by undersea transmission cables.
I can assume of some deliberate offshore wind tasks that didn’t go forward — the proponents allowed their energy buy agreements (PPAs) to lapse — largely due to the transmission subject, inflation and total enhance to prices.
Regulatory points: new however previous
Though there could also be fewer regulatory points for wind builders after they step into the water, that’s not the identical as there being no issues.
These points may be tougher to navigate than on land, just because wind energy venture growth within the water is a current change for a lot of regulatory companies. There’s a studying curve for everybody.
A few of these conditions take care of whether or not it’s state or federal waters being mentioned. States have jurisdiction to various extents into the water, past which federal jurisdiction takes over.
What might make offshore growth simpler is that a number of states are accustomed to the allowing course of for oil and fuel offshore growth. This consists of the idea of lease blocks being bought at public sale, the environmental and social evaluation course of, and even the necessity to carry the vitality from the place it’s sourced offshore, to land. Whether or not it’s about laying an undersea pipeline or an underwater electrical cable, the impacts are comparable and a lot of the regulatory atmosphere is comparable.

This consists of the necessity to defend the undersea atmosphere from hurt, together with safety for fish and their spawning grounds. It’s essential to find out whether or not there are any species in danger concerned, one of the vital delicate areas typically being the near-shore and shoreline atmosphere. Generally it might be essential to plan a route round a delicate space akin to a fish-spawning grounds — making an allowance for {that a} non-direct route will enhance prices, in addition to energy attenuation losses.
Within the allowing course of, after the venture promoter has obtained rights to a parcel of seafloor, their first step is to arrange a website evaluation plan. This covers issues akin to a geological and geophysical survey, a seek for environmentally delicate areas, and a examine for historic sources akin to shipwrecks. This course of is coordinated by BOEM. If the location evaluation signifies no main areas of concern, BOEM will request a development and operations plan, to incorporate data akin to the kind and site of generators, undersea services akin to anchors and cables, in addition to electrical conduits to hold the facility generated to shore.
Expertise has discovered this may take as much as 5 years — two for the location evaluation plan, and three extra for the development and operations plan evaluation.
Discovering an answer to stakeholder priorities
Within the offshore, there could also be a variety of stakeholders, together with:
Navy – The U.S. Navy and Coast Guard might have issues in regards to the location of wind generators and can should be introduced into concerns early within the course of. The army might have necessities on turbine location, because it pertains to plane taking off and touchdown at coastal army bases, and coaching airspace.
Harbors and transport – These pursuits are involved about free and protected navigation and can need current transport fairways left clear for navigation.
Fishing trade – This sector could also be involved about harm to their fishery useful resource, restricted entry to fishing grounds, threat to spawning grounds and potential harm that their nets and the undersea infrastructure might do to one another.
Indigenous teams – Many Indian tribes and people really feel they’ve been handled as a field to be checked and haven’t been adequately consulted about offshore growth. In lots of circumstances, ocean views have a robust religious worth, and so they need these preserved. Having a strong tribal engagement plan is essential. Many Indigenous tribes wish to transfer past session to changing into a accomplice within the growth course of.
Particular person property homeowners and tourism promoters – Unspoiled views over the water are a giant attraction for many individuals, and the prospect of getting that view crammed with wind generators can lead to many indignant calls to political representatives. In some conditions the place offshore drilling and manufacturing platforms are a well-known sight, there could also be much less opposition to offshore wind energy growth.
New developments in transmission allowing
As offshore wind energy turns into extra widespread in the US, many of those points will grow to be higher understood. We count on that extra jurisdictions will streamline their processes as New Zealand has achieved, the place one company handles a lot of the consultative course of.
Wind builders might additionally group up to make use of a standard hall for his or her underwater transmission traces — corridors which have already been authorized to be used, and including extra underwater services might be much less of a problem for regulators and different stakeholders.
From a gradual begin, offshore wind energy in the US has a vibrant future. A lot of the nation’s inhabitants and energy markets are alongside the coast, so having renewable vitality sources positioned just some miles offshore will assist energy a extra renewable future.
Tershara Matthews is the U.S. offshore wind coverage lead for WSP USA. She develops quite a lot of offshore vitality, restoration, infrastructure and different environmental tasks whereas selling robust regulatory and stakeholder outreach with a enterprise growth emphasis on offshore wind and vitality transition. She has a particular give attention to offshore wind initiatives within the Gulf Coast. Matthews beforehand served as a supervisory program administration specialist for the Bureau of Ocean Power Administration (BOEM) workplace in New Orleans, in addition to a former senior chief with the BOEM workplace within the Gulf of Mexico.
