America's First Large-Scale Offshore Wind Project Finally Finishes Construction (wbur.org) 71

It's America's first large-scale offshore wind project, reports WBUR — enough clean energy to power 400,000 homes in Massachusetts from 62 offshore wind turbines generating 800 megawatts.

But it took a while... The plant's first construction delay happened back in 2019, they point out — and then "Just three months ago, when the project was 95% complete, the U.S. Interior Department issued a stop-work order." But after successfully challenging that order in court, and "with a stretch of good weather offshore, the developers behind the $4.5 billion project managed to get over the finish line."

The Associated Press notes it was "one of five major East Coast offshore wind projects the Trump administration halted construction on days before Christmas, citing national security concerns." Developers and states sued, and federal judges allowed all five to resume construction, essentially concluding that the government did not show that the national security risk was so imminent that construction must halt. Another one of the five, Revolution Wind, began sending power for the first time to New England's electric grid on Friday and will scale up in the weeks ahead until it is fully operational.
"That project is nearly complete as well," notes WBUR, "and will eventually be capable of powering up to 350,000 homes."

    I'm a fan of this!

    • I like how the summary says it can power 400k homes in the first paragraph and 350k homes in the last. I know how rounding works but that is funny. And of course cost is sort of mentioned but not compared to onshore options.

        the summary says it can power 400k homes in the first paragraph and 350k homes in the last.

        Try reading it again. It says the project can power 400k homes and then there is another project called Revolution Wind that will be able to power 350k.

        • That's in absolutely perfect conditions. Divide 400,000 by 3 for a reasonable average, by 6 for a calmer day, and realize that there will be days when the whole project produced nothing.

          Got backup?

          In January the BPA had a 13 day run where the 2800 MW of installed wind produced less than 10% of nameplate. Hopefully the offshore turbines will do better.

          • No I think you're mistaken. The capacity is 800 MW, with a capacity factor of 40%-50%, which assuming 1 kW on average per home comes out to about 350,000 or 400,000 homes.

    Yeah, until Kegsbreath and Trump decide to use it for target practice.

    • This is his (much overused) go-to excuse so he can try to rule by fiat and bypass Congressional approval and some/most Judicial review - it's usually complete bullshit. I think even his die-hard supporters are (more) dubious now.

        It'll be about birds killed, most likely.

        Of which under a million were killed by wind farms annually. On the other end of the scale, over a billion were killed annually by domestic cats. Somewhere in the middle lies other bird killers like buildings (birds flying into windows).

        That and "national emergency".

        I'm hoping the silver lining we'll get out of the debacle of the last ten years is a renewed respect for federalism and separation of powers. I'm not holding my breath. People are stunningly resistant to realizing it won't always be your friends and allies wielding that power you want to hand out. "We can let the President use his judgement, surely he'll use it with restraint and for the good of the entire country; if he errs, how bad can it be?"

        Very, very bad, as it turns out.

  • So how is this going to affect consumer electrical rates in Massachusetts? Anybody documenting this?

      According to filings I was able to find, The Commonwealth has a 20 year procurement contract with Vineyard Wind for 6.5c/kwh (2017 dollars, about 8.5c/kwh today). Or $85/MWh

      In January the average wholesale electricity price was about $124/MWh.

      This doesn't mean the average customer will see a ~30% drop in their utility bill of course, but this is definitely adding cheaper power to the market which in turn should bring utility bills down.

      • That ain't too bad, though that average wholesale price of $124/MWh seems kinda high. Would have to do some poking around for comparison data later to see other regional pricing schemes.

        Fwiw the consumer (not wholesale) price per kWh around here is $0.12-$0.13 which is roughly the same as the wholesale price you indicated for Mass. Quote a difference. We don't have many solar or wind inputs.

        • I got the average price by downloading the Jan 2026 data set from here and using the average() function in a spreadsheet; Max is 681, min is -538 (excess renewables tend to drive wholesale prices into the negatives). Bulk average is 124.

        Averages aren't really a useful way to determine if a generating asset will have an impact in wholesale markets. For one, wind output is highly variable but follows broad seasonal and daily patterns. It's very possible for the bulk of the output of the wind farm to be in periods when power would already be cheap. One particular bit of trouble you run into is the wind lowers the price in off-peak hours, but the system still needs expensive power units to stay online to help cover the peak hours (imagine a co

        • Congrats, sciencebard! Someone who actually knows their shit!
          "1,000,000 points for Gryffindor!"

          I'd tag wind and solar as backups for when the 'grid' needs a little extra... maybe they can charge the warehouse-sized battery backup for the precious data center... but there's no way the wind and solar farms are going to meet the needs of "Clod".

      • Assuming, of course, the customers actually see any decrease at all... very most likely, it won't change one cent (possibly even go up... gotta pay for the installation of the things, maintenance costs, some guy to scrub the barnacles off the mast, and pad the C-suites pockets).

        • This is a procurement contract. It has been agreed that the Commonwealth will buy electricity from them at (effectively) 8.5c/kwh and give permission to Vineyard Wind to build their wind turbines in the designated location.

          It is entirely on Vineyard Wind to deliver their end of the bargain. Everything you mention - installation, maintenance, profits - is entirely on Vineyard Wind. They are locked in to selling their electricity for 8.5c/kwh because that's the contract terms. If they can't make a profit at t

    Not how I thought it was done.

    • Its actually how most fixed offshore installations are done. A ship goes out and installs a jacket (the legs, which fun fact are just tossed into the water and float and towed out to where they need to be until they are sunk in a controlled manner), and another ship comes afterwards and just sets a pre-fabricated thing on top. Seeing basically an entire oil platform lifted from a barge onto its jacket is one of the single most impressive things I've ever seen. The ships that do that are frigging massive.

    • Whaaaaaaaaaaaaaaaaaaaaaaaaat?

      Wow, I did not expect that the ship would have to be on its own stilts! It makes sense, but I hadn't expected it. Pretty neat.

      But, it also tells me why people who live on the shore don't want them. If you're paying a premium for ocean views, and instead see those, well, I get it. Did not know they were so close to shore.

    ... as a hoity-toity resident of Martha's Vineyard, there's only one thing that looks more attractive than an offshore wind farm. And that's an abandoned offshore wind farm project.
