American wind power congratulates President-elect Biden on his victory.

Microgrid solar outage algorithms optimize renewable energy during blackouts using grid-forming inverters, islanding control, demand forecasting, and energy storage from batteries and EVs, improving reliability by up to 35% for resilient power sharing.

Key Points

Algorithms that island homes, forecast demand, and prioritize critical loads using storage and grid-forming inverters.

✅ Disconnects inverters to form resilient neighborhood microgrids

✅ Forecasts solar, wind, and demand; allocates energy fairly

✅ Uses EVs and batteries; boosts reliability by up to 35%

Some people who have solar panels on their roof are under the impression that they can use them to power their home in the case of an outage, but that simply is not the case. Homes do remain connected to the grid during outages, as U.S. power outage risks grow, but the devices tasked with managing solar panels are normally turned off due to safety concerns. This permanent grid connection essentially prevents homeowners from drawing on the power that their own renewable energy resources generate.

This could be about to change, however, thanks to the efforts of a team of University of California San Diego engineers who have come up with algorithms that would enable homes to share and use their power in outages by disconnecting solar inverters from the grid. Their algorithms work with the existing technology and would have the added benefit of boosting the system’s reliability by as much as 35 percent.

The genius of their work lies in the ability of the algorithm to prioritize the distribution of power from the renewable resources in outages. Their equation considers forecasts for wind and solar power generation to address clean energy intermittency challenges and the available energy storage, including batteries and electric vehicles. It combines this information with the projected energy usage of residents and the amount of energy the homes are able to produce. It can be programmed to prioritize in several different ways, the most vital of which is by favoring those who need power urgently, such as those using life support equipment. It could also prioritize those who are willing to pay extra or reward those who typically generate an energy surplus during normal operations.

Learning lessons from past outages

Lead author Abdulelah H. Habib said the engineers were inspired to find a way to use the renewable power in outages by the events of Hurricane Sandy. This storm affected more than eight million people on the nation’s East Coast, some of whom were left without power for as long as two weeks.

According to the researchers, most customers prefer sharing community-scale storage systems over having systems in each home because of the lower costs. One of the paper’s senior authors, Raymond de Callafon, said that homes that are connected together are not only more resilient in power outages but they also happen to be more resilient to price fluctuations.

Each home needs to be equipped with special circuit breakers that can be remotely controlled, while utilities would need to install some communications methods so the power systems within a particular residential cluster can communicate amongst themselves. They also need a “grid forming inverter” to help them connect to one another and manage excess solar on networks safely.

One stumbling block that will have to be overcome is the current regulations. Most states do not allow individual homeowners to sell power to other homeowners, so there would have to be some adjustments to make this a reality.

Solar power growing in popularity

Solar power’s popularity is currently on the rise, and reductions in cost as the technology improves are only expected to drive this growth even further. REC CEO Steve O’Neil told CNBC that the installation rates of solar double every two years, a trend that informs residential solar economics for homeowners even though just two percent of the planet’s electricity comes from converting sunlight to energy. This means there is plenty of room for expansion. The world’s current solar capacity is 305 gigawatts, compared to just 50 gigawatts in 2010.

In addition, he pointed out that the price of solar energy has dropped by 70 percent since the year 2010 and continues to fall; it costs around eight cents per kilowatt hour at the moment. Another factor that could boost adoption is storage improvements, driven by affordable solar batteries that expand capacity, which will allow solar energy to be used even on overcast days.

EV Charging Coal and Oil Claim: Fact-check of kWh, CO2 emissions, and electricity grid mix shows 70 lb coal or ~8 gallons oil per 66 kWh, with renewables and natural gas reducing lifecycle emissions.

Key Points

A viral claim on EV charging overstates oil use; accurate figures depend on grid mix: ~70 lb coal or ~8 gallons oil.

✅ About 70 lb coal or ~8 gal oil per 66 kWh, incl. conversion losses

✅ EVs average ~100 g CO2 per mile vs ~280 g for 30 mpg cars

✅ Grid mix includes renewables, nuclear, natural gas; oil use is low

The claim: Average electric car requires equivalent of 85 pounds of coal or six barrels of oil for a single charge

The Biden administration has pledged to work towards decarbonizing the U.S. electricity grid by 2035. And the recently passed $1.2 trillion infrastructure bill provides funding for more electric vehicle (EV) charging infrastructure, including EV charging networks across the country under current plans.

However, a claim that electric cars require an inordinate amount of oil or coal energy to charge has appeared on social media, even as U.S. plug-ins traveled 19 billion miles on electricity in 2021.

“An average electric car takes 66 KWH To charge. It takes 85 pounds of coal or six barrels of oil to make 66 KWH,” read a Dec 1 Facebook post that was shared nearly 500 times in a week. “Makes absolutely no sense.” 

The post included a stock image of an electric car charging, though actual charging costs depend on local rates and vehicle efficiency.

This claim is in the ballpark for the coal comparison, but the math on the oil usage is wildly inaccurate.

It would take roughly 70 pounds of coal to produce the energy required to charge a 66 kWh electric car battery, said Ian Miller, a research associate at the MIT Energy Initiative. That's about 15 pounds less than is claimed in the post.

The oil number is much farther off.

While the post claims that it takes six barrels of oil to charge a 66 kWh battery, Miller said the amount is closer to 8 gallons  — the equivalent of 20% of one barrel of oil.

He said both of his estimates account for energy lost when fossil fuels are converted into electricity. 

"I think the most important question is, 'How do EVs and gas cars compare on emissions per distance?'," said Miller. "In the US, using average electricity, EVs produce roughly 100 grams of CO2 per mile."

He said this is more than 60% less than a typical gasoline-powered car that gets 30 mpg, aligning with analyses that EVs are greener in all 50 states today according to recent studies. Such a vehicle produces roughly 280 grams of CO2 per mile.

Lifecycle analyses also show that the CO2 from making an EV battery is not equivalent to driving a gasoline car for years, which often counters common misconceptions.

"If you switch to an electric vehicle, even if you're using fossil fuels (to charge), it's just simply not true that you'll be using more fossil fuel," said Jessika Trancik, a professor at the Massachusetts Institute of Technology who studies the environmental impact of energy systems.  

However, she emphasized electric cars in the U.S. are not typically charged using only energy from coal or oil, and that electricity grids can handle EVs with proper management.

The U.S. electricity grid relies on a diversity of energy sources, of which oil and coal together make up about 20 percent, according to a DOE spokesperson. This amount is likely to continue to drop as renewable energy proliferates in the U.S., even as some warn that state power grids will be challenged by rapid EV adoption. 

"Switching to an electric vehicle means that you can use other sources, including less carbon-intensive natural gas, and even less carbon-intensive electricity sources like nuclear, solar and wind energy, which also carry with them health benefits in the form of reduced air pollutant emissions," said Trancik. 

Our rating: Partly false
Based on our research, we rate PARTLY FALSE the claim that the average electric car requires the equivalent of 85 pounds of coal or six barrels of oil for a single charge. The claim is in the ballpark on coal consumption, as an MIT researcher estimates that around 70 pounds. But the oil usage is only about 8 gallons, which is 20% of one barrel. And the actual sources of energy for an electric car vary depending on the energy mix in the local electric grid.

US Renewable Energy Cost Advantage signals cheaper utility-scale solar and onshore wind versus natural gas, with LCOE declines, tax credits, and climate policy cutting electricity costs for utilities and grids across the United States.

Key Points

Cheaper solar and wind than natural gas, driven by LCOE drops, tax credits, and policy, lowering US electricity costs.

✅ Utility-scale solar is about one-third cheaper than gas

✅ Onshore wind costs roughly 44 percent less than natural gas

✅ Policy and tax credits accelerate renewables and cut power prices

Natural gas’s dominance as power-plant fuel in the US is fading fast as the cost of electricity generated by US wind and solar projects tumbles and as wind and solar surpass coal in the generation mix, according to Guggenheim Securities.

Utility-scale solar is now about a third cheaper than gas-fired power, while onshore wind is about 44% less expensive, Guggenheim analysts led by Shahriar Pourreza said Monday in a note to clients, a dynamic consistent with falling wholesale power prices in several markets today. 

“Solar and wind now present a deflationary opportunity for electric supply costs,” the analysts said, which “supports the case for economic deployment of renewables across the US,” as the country moves toward 30% wind and solar and one-fourth of total generation in the near term.

Gas prices have surged amid a global supply crunch after Russia’s invasion of Ukraine, while tax-credit extensions and sweeping US climate legislation have brought down the cost of wind and solar, even as renewables surpassed coal in 2022 nationwide. Renewables-heavy utilities like NextEra Energy Inc. and Allete Inc. stand to benefit, and companies that can boost spending on wind and solar, as wind, solar and batteries dominate the 2023 pipeline, will also see faster growth, Guggenheim said.

Vineyard Wind Offshore Wind Farm delivers clean power to Massachusetts near Martha's Vineyard, with 62 turbines and 800 MW capacity, advancing renewable energy, cutting carbon, lowering costs, and driving net-zero emissions and green jobs.

Key Points

An 800 MW Massachusetts offshore project of 62 turbines supplying clean power to 400,000+ homes and cutting emissions.

✅ 800 MW powering 400,000+ MA homes and businesses

✅ 62 turbines, 13 MW each, 15 miles from Martha's Vineyard

✅ Cuts 1.6M tons CO2 annually; boosts jobs and port infrastructure

The crisp Atlantic air off the coast of Martha's Vineyard carried a new melody on February 2nd, 2024. Five colossal turbines, each taller than the Statue of Liberty, began their graceful rotations, marking the historic moment power began flowing from Vineyard Wind, the first large-scale offshore wind farm in the United States, enabled by Interior Department approval earlier in the project timeline. This momentous occasion signifies a seismic shift in Massachusetts' energy landscape, one that promises cleaner air, lower energy costs, and a more sustainable future for generations to come.

Nestled 15 miles southeast of Martha's Vineyard and Nantucket, Vineyard Wind is a colossal undertaking. The project, a joint venture between Avangrid Renewables and Copenhagen Infrastructure Partners, will ultimately encompass 62 turbines, each capable of generating a staggering 13 megawatts. Upon full completion later this year, Vineyard Wind will power over 400,000 homes and businesses across Massachusetts, contributing a remarkable 800 megawatts to the state's energy grid.

But the impact of Vineyard Wind extends far beyond mere numbers. This trailblazing project holds immense environmental significance. By harnessing the clean and inexhaustible power of the wind, Vineyard Wind is projected to annually reduce carbon emissions by a staggering 1.6 million metric tons – equivalent to taking 325,000 cars off the road. This translates to cleaner air, improved public health, and a crucial step towards mitigating the climate crisis.

Governor Maura Healey hailed the project as a "turning point" in Massachusetts' clean energy journey. "Across the Commonwealth, homes and businesses will now be powered by clean, affordable energy, contributing to cleaner air, lower energy costs, and pushing us closer to achieving net-zero emissions," she declared.

Vineyard Wind's impact isn't limited to the environment; it's also creating a wave of economic opportunity. Since its inception in 2017, the project has generated nearly 2,000 jobs, with close to 1,000 positions filled by union workers thanks to a dedicated Project Labor Agreement. Construction has also breathed new life into the New Bedford Marine Commerce Terminal, with South Coast construction activity accelerating around the port, transforming it into the nation's first port facility specifically designed for offshore wind, showcasing the project's commitment to local infrastructure development.

"Every milestone on Vineyard Wind 1 is special, but powering up these first turbines stands apart," emphasized Pedro Azagra, CEO of Avangrid Renewables. "This accomplishment reflects the years of dedication and collaboration that have defined this pioneering project. Each blade rotation and megawatt flowing to Massachusetts homes is a testament to the collective effort that brought offshore wind power to the United States."

Vineyard Wind isn't just a project; it's a catalyst for change. It perfectly aligns with Massachusetts' ambitious clean energy goals, which include achieving net-zero emissions by 2050 and procuring 3,200 megawatts of offshore wind by 2028, while BOEM lease requests in the Northeast continue to expand the development pipeline across the region. As Energy and Environmental Affairs Secretary Rebecca Tepper stated, "Standing up a new industry is no easy feat, but we're committed to forging ahead and growing this sector to lower energy costs, create good jobs, and build a cleaner, healthier Commonwealth."

The launch of Vineyard Wind transcends Massachusetts, serving as a beacon for the entire U.S. offshore wind industry, as New York's biggest offshore wind farm moves forward to amplify regional momentum. This demonstration of large-scale development paves the way for further investment and growth in this critical clean energy source. However, the journey isn't without its challenges, and questions persist about reaching 1 GW on the grid nationwide as stakeholders navigate timelines. Concerns regarding potential impacts on marine life and visual aesthetics remain, requiring careful consideration and ongoing community engagement.

Despite these challenges, Vineyard Wind stands as a powerful symbol of hope and progress. It represents a significant step towards a cleaner, more sustainable future, powered by renewable energy sources at a time when U.S. offshore wind is about to soar according to industry outlooks. It's a testament to the collaborative effort of policymakers, businesses, and communities working together to tackle the climate crisis. As the turbines continue their majestic rotations, they carry a message of hope, reminding us that a brighter, more sustainable future is within reach, powered by the wind of change.

Additional Considerations:

• The project boasts a dedicated Fisheries Innovation Fund, fostering collaboration between the fishing and offshore wind industries to ensure sustainable coexistence.
• Vineyard Wind has invested in education and training programs, preparing local residents for careers in the burgeoning wind energy sector.
• The project's success opens doors for further offshore wind development in the U.S., such as Long Island proposals gaining attention, paving the way for a clean energy revolution.

Inflation Reduction Act Clean Energy drives EV adoption and renewable power, but grid interconnection, permitting, and supply chain bottlenecks slow wind, solar, and offshore projects, risking emissions targets despite domestic manufacturing growth and tax incentives.

Key Points

An IRA push to scale EVs and renewables, meeting EV goals but lagging wind and solar amid grid and permitting delays.

✅ EV sales up 50%, 9.2% of 2023 new cars; growth may moderate.

✅ 32.3 GW added, below 46-79 GW/year needed for climate targets.

✅ Grid, permitting, and supply chain delays bottleneck wind and solar.

A year and a half following President Biden's enactment of an ambitious climate change bill, the landscape of the United States' clean energy transition, shaped by 2021 electricity lessons, presents a mix of successes and challenges. A recent study by a consortium of research organizations highlights that while electric vehicle (EV) sales have surged, aligning with the law's projections, the expansion of renewable energy sources like wind and solar has encountered significant hurdles.

The legislation, known as the Inflation Reduction Act, aimed for a dual thrust in America's climate strategy: boosting EV adoption, alongside EPA emission limits, and significantly increasing the generation of electricity from renewable resources. The Act, passed in 2022, was anticipated to propel the United States toward reducing its greenhouse gas emissions by approximately 40 percent from 2005 levels by the end of this decade, backed by extensive financial incentives for clean energy advancements.

Electric vehicle sales have indeed seen a remarkable uptick, with a more than 50 percent increase over the past year, as EV sales surge into 2024 across the market, culminating in EVs comprising 9.2 percent of all new car sales in the United States in 2023. This growth trajectory met the upper range of analysts' predictions post-law enactment, signaling a strong start toward achieving the Act's emission reduction targets.

However, the EV market faces uncertainties regarding the sustainability of this rapid growth. The initial surge in sales was largely driven by early adopters, and the market now confronts challenges such as high prices and limited charging infrastructure, while EVs still trail gas cars in overall market share. Despite these concerns, projections suggest that even a slowdown to 30-40 percent growth in EV sales for 2024 would align with the law's emission goals.

The renewable energy sector's progress is less straightforward. Despite achieving a record addition of 32.3 gigawatts of clean electricity capacity in the past year, the pace falls short of the projected 46 to 79 gigawatts needed annually to meet the United States' climate objectives. While there is potential for about 60 gigawatts of projects in the pipeline for this year, not all are expected to materialize on schedule, indicating a lag in the deployment of new renewable energy sources.

Logistical challenges are a significant barrier to scaling up renewable energy, especially as EV-driven electricity demand rises in the coming years. Lengthy grid connection processes, permitting delays, and local opposition hinder wind and solar project developments. Moreover, ambitious plans for offshore wind farms are hampered by supply chain issues and regulatory constraints.

To achieve the Inflation Reduction Act's ambitious targets, the United States needs to add 70 to 126 gigawatts of renewable capacity annually from 2025 to 2030—a formidable task given the current logistical and regulatory bottlenecks. The analysis underscores the urgency of addressing these non-cost barriers to unlock the full potential of the law's clean energy and emissions reduction ambitions.

In addition to promoting clean energy generation and EV adoption, the Inflation Reduction Act has spurred domestic manufacturing of clean energy technologies. With $44 billion invested in U.S. clean-energy manufacturing last year, this aspect of the law has seen considerable success, and permanent clean energy tax credits are being debated to sustain momentum, demonstrating the Act's capacity to drive economic and industrial transformation.

The law's impact extends to emerging clean energy technologies, offering tax incentives for advanced nuclear reactors, renewable hydrogen production, and carbon capture and storage projects. While these initiatives hold promise for further emissions reductions, their development and deployment are still in the early stages, with tangible outcomes expected in the longer term.

While the Inflation Reduction Act has catalyzed significant strides in certain areas of the United States' clean energy transition, including an EV inflection point in adoption trends, it faces substantial hurdles in fully realizing its objectives. Overcoming logistical, regulatory, and market challenges will be crucial for the nation to stay on course toward its ambitious climate goals, underscoring the need for continued innovation, investment, and policy refinement in the journey toward a sustainable energy future.

Vineyard Wind I advances as BOEM issues a final environmental impact statement for the 800 MW offshore wind farm south of Martha's Vineyard, delivering clean energy, jobs, and carbon reductions to Massachusetts toward net-zero.

Key Points

An 800 MW offshore wind project near Martha's Vineyard supplying clean power to Massachusetts.

✅ 800 MW capacity; power for 400,000+ homes and businesses

✅ BOEM final EIS; record of decision pending within 30+ days

✅ 1.68M metric tons CO2 avoided annually; jobs and lower rates

Federal environmental officials have completed their review of the Vineyard Wind I offshore wind farm, moving the project that is expected to deliver clean renewable energy to Massachusetts by the end of 2023 closer to becoming a reality.

The U.S. Department of the Interior said Monday morning that its Bureau of Ocean Energy Management completed the analysis it resumed about a month ago, published the project's final environmental impact statement, and said it will officially publish notice of the impact statement in the Federal Register later this week.

"More than three years of federal review and public comment is nearing its conclusion and 2021 is poised to be a momentous year for our project and the broader offshore wind industry," Vineyard Wind CEO Lars Pedersen said. "Offshore wind is a historic opportunity to build a new industry that will lead to the creation of thousands of jobs, reduce electricity rates for consumers and contribute significantly to limiting the impacts of climate change. We look forward to reaching the final step in the federal permitting process and being able to launch an industry that has such tremendous potential for economic development in communities up and down the Eastern seaboard."

The 800-megawatt wind farm planned for 15 miles south of Martha's Vineyard was the first offshore wind project selected by Massachusetts utility companies with input from the Baker administration to fulfill part of a 2016 clean energy law. It is projected to generate cleaner electricity for more than 400,000 homes and businesses in Massachusetts, produce at least 3,600 jobs, reduce costs for Massachusetts ratepayers by an estimated $1.4 billion, and eliminate 1.68 million metric tons of carbon dioxide emissions annually.

Offshore wind power, informed by the U.S. offshore wind outlook, is expected to become an increasingly significant part of Massachusetts' energy mix. The governor and Legislature agree on a goal of net-zero carbon emissions by 2050, but getting there is projected to require having about 25 gigawatts of offshore wind power. That means Massachusetts will need to hit a pace in the 2030s where it has about 1 GW of new offshore wind power on the grid coming online each year.

"I think that's why today's announcement is so historic, because it does represent that culmination of work to understand how to permit and build a cost-effective and environmentally-responsible wind farm that can deliver clean energy to Massachusetts ratepayers, but also just how to do this from start to finish," said Energy and Environmental Affairs Secretary Kathleen Theoharides. "As we move towards our goal of probably [25 GW] of offshore wind by 2050 to hit our net-zero target, this does give us confidence that we have a much clearer path in terms of permitting."

She added, "There's a huge pipeline, so getting this project out really should open the door to the many additional projects up and down the East Coast, such as Long Island proposals, that will come after it."

According to the American Wind Energy Association, there are expected to be 14 offshore projects totaling 9,112 MW of capacity in operation by 2026.

Susannah Hatch, the clean energy coalition director for the Environmental League of Massachusetts and a leader of the broad-based New England for Offshore Wind Regional group, called offshore wind farms like Vineyard Wind "the linchpin of our decarbonization efforts in New England." She said the Biden administration's quick action on Vineyard Wind is a positive sign for the burgeoning sector.

"Moving swiftly on responsibly developed offshore wind is critical to our efforts to mitigate climate change, and offshore wind also provides an enormous opportunity to grow the economy, create thousands of jobs, and drive equitable economic benefits through increased minority economic participation in New England," Hatch said.

With the final environmental impact statement published, Vineyard Wind still must secure a record of decision from BOEM, which processes wind lease requests, an air permit from the Environmental Protection Agency and sign-offs from the U.S. Army Corps of Engineers and the National Marine Fisheries Service to officially clear the way for the project that is on track to be the nation's first utility-scale offshore wind farm. BOEM must wait at least 30 days from the publication of the final environmental impact statement to issue a record of decision.

Project officials have said they expect the final impact statement and then a record of decision "sometime in the first half of 2021." That would allow the project to hit its financial close milestone in the second half of this year, begin on-shore work quickly thereafter, start offshore construction in 2022, begin installing turbines in 2023 and begin exporting power to the grid, marking Vineyard Wind first power, by late 2023, Pedersen said in January.

"Offshore energy development provides an opportunity for us to work with Tribal nations, communities, and other ocean users to ensure all decisions are transparent and utilize the best available science," BOEM Director Amanda Lefton said.

The commercial fishing industry has been among the most vocal opponents of aspects of the Vineyard Wind project and the Responsible Offshore Development Alliance (RODA) has repeatedly urged the new administration to ensure the voices of the industry are heard throughout the licensing and permitting process.

In comments submitted earlier this month in response to a BOEM review of an offshore wind project that is expected to deliver power to New York, including the recent New York offshore wind approval, RODA said the present is "a time of significant confusion and change in the U.S. approach to offshore wind energy (OSW) planning" and detailed mitigation measures it wants to see incorporated into all projects.

"To be clear, none of these requests are new -- nor hardly radical. They have simply been ignored again, and again, and again in a political push/pull between multinational energy companies and the U.S. government, leaving world-famous seafood, and the communities founded around its harvest, off the table," the group said in a press release last week. Some of RODA's suggestions were analyzed as part of BOEM's Vineyard Wind review.

Vineyard Wind has certainly taken a circuitous path to get to this point. The timeline for the project was upended in August 2019 when the Trump administration decided to conduct a much broader assessment of potential offshore wind projects up and down the East Coast, which delayed the project by almost a year.

When the Trump administration delayed its action on a final environmental impact statement last year, Vineyard Wind on Dec. 1 announced that it was pulling its project out of the federal review pipeline in order to complete an internal study on whether the decision to use a certain type of turbine would warrant changes to construction and operations plan. The Trump administration declared the federal review of the project "terminated."

Within two weeks of President Joe Biden being inaugurated, Vineyard Wind said its review determined no changes were necessary and the company resubmitted its plans for review. BOEM agreed to pick up where the Trump administration had left off despite the agency previously declaring its review terminated.

"It would appear that fishing communities are the only ones screaming into a void while public resources are sold to the highest bidder, as BOEM has reversed its decision to terminate a project after receiving a single letter from Vineyard Wind," RODA said.

The final environmental impact statement that BOEM published Monday showed that the federal regulators believe the Vineyard Wind I development as proposed will have "moderate" impacts on commercial fisheries and for-hire recreational fishing outfits, and that the project combined with other factors not related to wind energy development will have "major" impacts on commercial and recreational fishing ventures.

Vineyard Wind pointed Monday to the fishery mitigation agreements it has entered into with Massachusetts and Rhode Island, a fishery science collaboration with the University of Massachusetts Dartmouth's School of Marine Science and Technology, and an agreement with leading environmental organizations around the protection of the endangered right whale.

Responding to concerns about safe navigation among RODA and others in the fishing sector, Vineyard Wind and the four other developers holding leases for offshore wind sites off New England agreed to orient their turbines in fixed east-to-west rows and north-to-south columns spaced one nautical mile apart. Last year, the U.S. Coast Guard concluded that the grid layout was the best way to maintain maritime safety and ease of navigation in the offshore wind development areas south of Martha's Vineyard and Nantucket.

Since a 2016 clean energy law kicked off the state's foray into the offshore wind world, Massachusetts utilities have contracted for a total of about 1,600 MW between two projects, Vineyard Wind I and Mayflower Wind.

A joint venture of Shell and Ocean Winds North America, Mayflower Wind was picked unanimously in 2019 by utility executives to build and operate a wind farm approximately 26 nautical miles south of Martha's Vineyard and 20 nautical miles south of Nantucket, with South Coast construction activity expected as the project progresses. The 804-megawatt project is expected to be operational by December 2025.

Massachusetts and its utilities are expected to go out to bid for up to another 1,600 MW of offshore wind generation capacity later this year using authorization granted by the Legislature in 2018.

The climate policy bill that Gov. Charlie Baker returned to the Legislature with amendments more than a month ago would require that the executive branch direct Massachusetts utilities to buy an additional 2,400 MW of offshore wind power.
