Massachusetts’ 1,200 MW Offshore Wind Project ‘no longer viable’ (rough waters ahead?)

By Robert Bradley Jr. -- November 2, 2022

“… global commodity price increases … sharp and sudden increases in interest rates, prolonged supply chain constraints, and persistent inflation have significantly increased the expected cost of constructing the project.”

Electricity rates are going up because of wind, solar, and batteries being forced upon, and duplicating, the grid. Reliability is going down because of wind and solar intermittency. And higher interest rates are (further) ruining the economics of the infrastructure-heavy, up-front capital necessary to turn “free” wind and solar into electricity.

It’s a perfect storm that might just overcome the taxpayer largesse of the federal subsidies (DOE and IRS) and rate averaging for captive ratepayers. With offshore wind experimental and extra-uneconomic, the worst can be assumed.

An October 30, 2022, article by Colin Young, “Major Massachusetts offshore wind project no longer viable,” explains the fluid situation.

A major offshore wind project in the Massachusetts pipeline “is no longer viable and would not be able to move forward” under the terms of contracts filed in May. Both developers behind the state’s next two offshore wind projects are asking state regulators to pause review of the contracts for one month amid price increases, supply shortages and interest rate hikes….

A one-month freeze, the developer said, “would give the parties an opportunity to evaluate the current situation facing the project and potentially agree upon changes to the PPAs, along with other measures, that could allow the project to return to viability.”

“As has been publicly reported in recent weeks, global commodity price increases, in part due to ongoing war in Ukraine, sharp and sudden increases in interest rates, prolonged supply chain constraints, and persistent inflation have significantly increased the expected cost of constructing the project. As a result, the project is no longer viable and would not be able to move forward absent amendments to the PPAs,” attorneys for Commonwealth Wind wrote in their motion.

The developer’s brief highlights “cost saving measures, tax incentives under the newly enacted Inflation Reduction Act, an increase in the PPA prices, and improvements to Project efficiencies” as the possible approaches to restoring their project to viability. The developer also said that it “remains fully committed to the project and to delivering cost-effective renewable energy from the project to the residents and businesses of Massachusetts in a manner that advances the purposes of [the state’s clean energy law] and the Commonwealth’s energy and climate policies.”

The Boston Globe reported last month that a top Avangrid executive told investors that the company expected Commonwealth Wind and Park City Wind (a project intended to provide power to Connecticut) to each be delayed by a year as they sought contract revisions. CEO Pedro Azagra said Commonwealth Wind is now expected to go live in 2028, the Globe reported….

Commonwealth Wind said that “the IRA benefits to the project are not fully known at this time and not anticipated to make the project economic absent other changes to the PPAs,” but told DPU that it “believes there may be potential opportunities to share benefits associated with the IRA with ratepayers and would be willing to explore those opportunities with stakeholders.”

It is unclear when a DPU decision will come, but the agency had previously set a Tuesday deadline for briefs related to the latest offshore wind contract….

Final Comment

The above article comes from the New Bedford Light, not the New York Times. But if the impasse continues without additional subsidies from Massachusetts authorities or captive ratepayers, it will deserve national attention.

One can only hope that local ratepayers reject associated rate hikes and preserve their shorelines at the same time. And may Commonwealth Wind’s problems serve as a warning that not only nuclear (Plant Vogtle) but also offshore wind is subject to significant risk to its developers.

    These issues were compounded for Coastal Virginia Offshore Wind by the Virginia State Corporation Commission, which stipulated that consumers be held harmless if CVOW’s capacity factor fell below 42% based on a 3 year trailing average. Dominion is not pleased and is threatening legal action or project cancellation.

    Also, none of the proposed offshore wind projects have yet addressed the need for storage to support the grid when the wind is not blowing.

    New Mexico regulators unanimously rejected a merger between this same multi-national wind-energy company, Avangrid, and the state’s public utility company, PNM, in December, 2021, partly because of its terrible track record in New England:


    What about the (what ought to be obvious) perils of allowing foreign companies, some of them geo-political foes, to have access to our energy grid? Crickets………

    The offshore wind electric transmission dilemma is two fold. By upgrading and using land routes to get to Boston the Massachusetts electric rate payers finance the project through their electric bills. By providing a submarine cable to Boston offshore wind contractors get a very expensive bill as XLPE submarine cable costs are prohibitive.
    The solution to provide the offshore submarine cable to Boston and additional locations is the Inflation Reduction Act. The IRA could provide an “enhanced planned off-shore transmission grid” that can significantly reduce the necessary onshore upgrades.
    The Inflation Reduction Act was signed into law on August 16, 2022, will significantly impact clean energy by providing 369 billion for energy and climate change programs. The Act directs around $369 billion toward energy and climate spending, including wind and clean energy storage.
    The act makes it simple to cash in renewable energy credits permitting direct pay for tax exempt groups and allows taxpayers to sell credits to unrelated parties. Out of 369 billion voted by Congress it makes sense to create a planned off-shore submarine cable grid to advance clean energy for the foreseeable future. Do it once and do it right.

    May seem minor, but our economic landscape has changed dramatically in last 2 years.
