O2 Tidal Turbine delivers tidal energy in Orkney, Scotland, supplying grid-connected renewable power via EMEC and enabling green hydrogen production, providing clean electricity with predictable generation from strong coastal currents.

 

Key Points

A 2 MW, grid-connected tidal device in Orkney that delivers clean power and enables EMEC green hydrogen production.

✅ 2 MW capacity; powers ~2,000 UK homes via EMEC grid

✅ Predictable renewable output from strong coastal currents

✅ Enables onshore electrolyzer to produce green hydrogen

 

“The world’s most powerful” tidal turbine has been hooked up to the onshore electricity grid in Orkney, a northerly archipelago in Scotland, and is ready to provide homes with clean, green electricity, even as a major UK offshore windfarm begins supplying power this week.

The tidal turbine, known as the O2, was developed by Scottish engineering firm Orbital Marine Power. On July 28, they announced O2 “commenced grid connected power generation” at the European Marine Energy Centre (EMEC) in Orkney, meaning it's all set up and providing energy to the local power grid, similar to another Scottish tidal project that recently powered nearly 4,000 homes.

The 74-meter-long (242-foot) turbine is said to be “the world’s most powerful” tidal turbine. It will lay in the waters off Orkney for the next 15 years with the capacity to meet the annual electricity demand of around 2,000 UK homes. The 2MW turbine is also set to power the EMEC’s land-based electrolyzer that will generate green hydrogen (hydrogen made without fossil fuels) that can also be used as a clean energy source, in a UK energy system that recently set a wind generation record for output.

“Our vision is that this project is the trigger to the harnessing of tidal stream resources around the world and, alongside investment in UK offshore wind, to play a role in tackling climate change whilst creating a new, low-carbon industrial sector,” Orbital CEO, Andrew Scott, said in a press release.

Tidal energy is harnessed by converting energy from the natural rise and fall of ocean tides and currents. The O2 turbine consists of two submerged blades with a 20-meter (65-foot) diameter attached to a turbine that will move with the shifting currents of Orkney’s coast to generate electricity. Electricity is then transferred from the turbine along the seabed via cables towards the local onshore electricity network, a setup also being used by a Nova Scotia tidal project to supply the grid today.


This method of harnessing energy is not just desirable because it doesn't release carbon emissions, but it’s more predictable than other renewable energy sources, such as solar or Scotland's wind farms that can be influenced by weather conditions. Tidal energy production is still in its infancy and there are relatively few large-scale tidal power plants in the world, but many argue that some parts of the world could potentially draw huge benefits from this innovative form of hydropower, especially coastal regions with strong currents such as the northern stretches of the UK and the Bay of Fundy in Atlantic Canada.

The largest tidal power operation in the world is the Sihwa Lake project on the west coast of South Korea, which harnesses enough power to support the domestic needs of a city with a population of 500,000 people. However, once fully operational, the MeyGen tidal power project in northern Scotland hopes to snatch its title.

Scores more wind turbines proposed for Long Island’s South Shore

New York Offshore Wind Expansion adds Equinor's Empire Wind 2 and Beacon Wind, boosting megawatts, turbines, and grid connections for Long Island and Queens, with jobs, assembly at South Brooklyn Marine Terminal, and clean energy.

 

Key Points

A statewide initiative proposing new Equinor and partner projects to scale offshore wind capacity, jobs, and grid links.

✅ Adds 2,490 MW via Empire Wind 2 and Beacon Wind

✅ Connects to Nassau County and Queens grids for reliability

✅ Creates 3,000+ NY jobs with South Brooklyn Marine Terminal work

 

Scores more 600-foot tall wind turbines would be built off Jones Beach under a new proposal.

Norwegian energy conglomerate Equinor has bid to create another 2,500 megawatts of offshore wind power for New York state and Long Island, where offshore wind sites are being evaluated, with two projects. One, which would connect to the local electric grid in Nassau County, would more than double the number of turbines off Long Island to some 200. A second would be built around 50 miles from Montauk Point and connect to the state grid in Queens. The plan would also include conducting assembly work in Brooklyn.

In disclosures Tuesday in response to a state request for proposals, Equinor said it would bolster its already state-awarded, 819-megawatt Empire Wind project off Long Island’s South Shore with another called Empire Wind 2 that will add 1,260 megawatts. Turbines of at least 10 megawatts each would mean that the prior project’s 80 or so turbines could be joined by another 120. Equinor’s federally approved lease area off Long Island encompasses some 80,000 acres, starting 15 miles due south of Long Beach and extending east and south.

Equinor on Tuesday also submitted plans to offer a second project called Beacon Wind that would be built 50 miles from Montauk Point, off the Massachusetts South Coast area. It would be 1,230 megawatts and connect through Long Island Sound to Queens.

Equinor said its latest energy projects would generate more than 3,000 New York jobs, including use of the South Brooklyn Marine Terminal for “construction activities” and an operations and maintenance base.

The new proposals came in response to a New York State Energy Research and Development Authority bid request for renewable projects in the state. In a statement, Siri Espedal Kindem, president of Equinor Wind U.S., said the company’s plans would include “significant new benefits for New York – from workforce training, economic development, and community benefits – alongside a tremendous amount of homegrown, renewable energy.”

Meanwhile, Denmark-based Orsted, working with New England power company Eversource, has also submitted plans for a new offshore wind project called Sunrise Wind 2, a proposal that includes “multiple bids” that would create “hundreds of new jobs, and infrastructure investment,” according to a company statement. Con Edison Transmission will also work to develop transmission facilities for that project, the companies said.

Orsted and Eversource already have contracts to develop a 130-megawatt wind farm for LIPA to serve the South Fork, and an 880-megawatt wind farm for the state. All of its hundreds of turbines would be based in a lease area off the coast of Massachusetts and Rhode Island, where Vineyard Wind has progressed as a key project.

“Sunrise Wind 2 will create good-paying jobs for New York, support economic growth, and further reduce emissions while delivering affordable clean energy to Long Island and the rest of New York,” Joe Nolan, executive vice president for Eversource, said in a statement.

Building Energy Celebrates the Beginning of Operations and Electricity Generation

Building Energy Iowa Wind Farm delivers 30 MW of renewable energy near Des Moines, generating 110 GWh annually with wind turbines, a long-term PPA, CO2 reduction, and community benefits like jobs and clean power.

 

Key Points

Building Energy Iowa Wind Farm is a 30 MW project generating 110 GWh a year, cutting CO2 and supporting local jobs.

✅ 30 MW capacity, 10 onshore turbines (3 MW each)

✅ ~110 GWh per year; power for 11,000 households

✅ Long-term PPA; jobs and emissions reductions in Iowa

 

With 110 GWh generated per year, the plant will be beneficial to Iowa's environment, reflecting broader Iowa wind power investment trends, contributing to the reduction of 100,000 tons of CO2 emissions, as well as providing economic benefits to host local communities.

Building Energy SpA, multinational company operating as a global integrated IPP in the Renewable Energy Industry, amid milestones such as Enel's 450 MW U.S. wind project, through its subsidiary Building Energy Wind Iowa LLC, announces the inauguration of its first wind farm in Iowa, which adds up to 30 MW of wind distribution generation capacity. The project, located north of Des Moines, in Story, Boone, Hardin and Poweshiek counties, will generate approximately 110 GWh per year. The beginning of operations has been celebrated on the occasion of the Wind of Life event in Ames, Iowa, in the presence of Andrea Braccialarghe, MD America of Building Energy, Alessandro Bragantini, Chief Operating Officer of Building Energy and Giuseppe Finocchiaro, Italian Consul General.

The overall investment in the construction of the Iowa distribution generation wind farms amounted to $58 million and it sells its energy and related renewable credits under a bundled, long-term power purchase agreement with a local utility, reflecting broader utility investment trends such as WEC Energy's Illinois wind stake in the region.

The wind facility, developed, financed, owned and operated by Building Energy, consists of ten 3.0 MW geared onshore wind turbines, each with a rotor diameter of 125 meters mounted on an 87.5 meter steel tower. The energy generated will satisfy the energy needs of 11,000 U.S. households every year, similar in community impact to North Carolina's first wind farm, while avoiding the emission of about 70,000 tons of CO2 emissions every year, according to US Environmental Protection Agency methodology, which is equivalent to taking 15,000 cars off the road each year.

Besides the environmental benefits, the wind farm also has advantages for the local community, providing it with clean energy and creating jobs for local Iowans. The project involved more than a hundred of local skilled workers during the construction phase. Some of those jobs will be also permanent as necessary for the operation and maintenance activities as well as for additional services such as delivery, transportation, spare parts management, landscape mitigation, and further environmental monitoring studies.

The Company is present in many US states since 2013 with more than 500 MW of projects under development, spread across different renewable energy technologies, and aligning with federal initiatives like DOE wind energy awards that support innovation.

"Remarkable" New Contract Award Adds 10 GW of Renewables to UK Grid

UK Renewable Energy Auction secures 10 GW for the grid at record-low costs, led by offshore wind, floating wind, solar, and onshore wind, with inflation-indexed CfDs delivering £37/MWh strike prices and enhanced energy security.

 

Key Points

Government CfDs add 10 GW of low-cost renewables to the UK grid via offshore wind, floating wind, and solar.

✅ 10 GW capacity: 7 GW offshore wind, 2.2 GW solar, 0.9 GW onshore wind

✅ Record-low £37/MWh offshore; floating wind at £87/MWh CfD strikes

✅ 15-year indexed contracts cut exposure to volatile gas prices

 

The United Kingdom will add 10 gigawatts (GW) of renewable energy capacity to its power grid at one-quarter the cost of fossil gas after concluding its biggest-ever renewable energy auction for new renewable supplies.

The “remarkable new UK renewable auction” will meet one-eighth of the country’s current electricity demand at record low prices of just £37 per megawatt-hour for offshore wind and £87 for floating offshore systems (a dynamic echoed as wind power gains in Canada across other markets), tweeted Carbon Brief Deputy Editor Simon Evans.

“The government is increasing its reliance on a local supply of renewables amid soaring UK power prices driven by a surge in the cost of natural gas following Russia’s invasion of Ukraine,” Bloomberg Green reports. Offshore wind energy “will add about seven gigawatts of clean power capacity to the nation’s fleet from 2026, bringing Britain closer to its target of installing 50 gigawatts by the end of the decade.”

The awards also include 2.2 gigawatts (that’s 2.2 billion watts) of solar and 900 megawatts of onshore wind, even as the UK faces a renewables backlog on some projects, Bloomberg says.

“Eye-watering gas prices are hitting consumers across Europe,” said UK Business and Energy Secretary Kwasi Kwarteng. “The more cheap, clean power we generate within our own borders, the better protected we will be from volatile gas prices that are pushing up bills.”

Citing government figures, Bloomberg says wind generation costs came in 5.8% lower than the previous auction in 2019, reflecting momentum in a sector set to become a trillion-dollar business this decade. Some of the winning bidders included Ørsted, Iberdrola’s Scottish Power unit, Vattenfall, and a consortium of AB Ignitis Grupe, EDP Renovaveis, and Engie.

Offshore wind power costs have fallen dramatically in recent years as the UK supported the industry to scale up and industrialize production of larger, more efficient turbines,” the news story states. Now, “the decline in price developers are willing to accept comes even after the cost of wind turbines rose in recent months as prices increased for key metals like steel and supply chain disruptions created expensive delays.”

The 15-year, fixed-price contracts will be adjusted for inflation when the turbines are ready to start delivering electricity, offering lessons for the U.S. wind sector on contract design.

World renewable power on course to shatter more records

Global Renewable Capacity Additions 2023 surge on policy momentum, high fossil prices, and energy security, with solar PV and wind leading growth as grids expand and manufacturing scales across China, Europe, India, and the US.

 

Key Points

Record solar PV and wind growth from policy and energy security, adding 440+ GW toward 4,500 GW total capacity in 2024.

✅ Solar PV to supply two-thirds of additions; rooftop demand rising.

✅ Wind rebounds ~70% as delayed projects complete in China, EU, US.

✅ Grid upgrades and better permitting, auctions key for 2024 growth.

 

Global additions of renewable power capacity are expected to jump by a third this year as growing policy momentum, higher fossil fuel prices and energy security concerns drive strong deployment of solar PV and wind power, building on a record year for renewables in 2016, according to the latest update from the International Energy Agency.

The growth is set to continue next year with the world’s total renewable electricity capacity rising to 4 500 gigawatts (GW), equal to the total power output of China and the United States combined, and in the United States wind power has surged in the electricity mix, says the IEA’s new Renewable Energy Market Update, which was published today.

Global renewable capacity additions are set to soar by 107 gigawatts (GW), the largest absolute increase ever, to more than 440 GW in 2023. The dynamic expansion is taking place across the world’s major markets. Renewables are at the forefront of Europe’s response to the energy crisis, accelerating their growth there. New policy measures are also helping drive significant increases in the United States, where solar and wind growth remains strong, and India over the next two years. China, meanwhile, is consolidating its leading position and is set to account for almost 55% of global additions of renewable power capacity in both 2023 and 2024.

“Solar and wind are leading the rapid expansion of the new global energy economy. This year, the world is set to add a record-breaking amount of renewables to electricity systems – more than the total power capacity of Germany and Spain combined,” said IEA Executive Director Fatih Birol. “The global energy crisis has shown renewables are critical for making energy supplies not just cleaner but also more secure and affordable – and governments are responding with efforts to deploy them faster. But achieving stronger growth means addressing some key challenges. Policies need to adapt to changing market conditions, and we need to upgrade and expand power grids to ensure we can take full advantage of solar and wind’s huge potential.”

Solar PV additions will account for two-thirds of this year’s increase in renewable power capacity and are expected to keep growing in 2024, according to the new report. The expansion of large-scale solar PV plants is being accompanied by the growth of smaller systems. Higher electricity prices are stimulating faster growth of rooftop solar PV, which is empowering consumers to slash their energy bills, and in the United States renewables' share is projected to approach one-fourth of electricity generation.

At the same time, manufacturing capacity for all solar PV production segments is expected to more than double to 1 000 GW by 2024, led by China's solar PV growth and increasing supply diversification in the United States, where wind, solar and battery projects dominate the 2023 pipeline, India and Europe. Based on those trends, the world will have enough solar PV manufacturing capacity in 2030 to comfortably meet the level of annual demand envisaged in the IEA’s Net Zero Emissions by 2050 Scenario.

Wind power additions are forecast to rebound sharply in 2023 growing by almost 70% year-on-year after a difficult couple of years in which growth was slugging, even as wind power still grew despite Covid-19 challenges. The faster growth is mainly due to the completion of projects that had been delayed by Covid-19 restrictions in China and by supply chain issues in Europe and the United States. However, further growth in 2024 will depend on whether governments can provide greater policy support to address challenges in terms of permitting and auction design. In contrast to solar PV, wind turbine supply chains are not growing fast enough to match accelerating demand over the medium-term. This is mainly due to rising commodity prices and supply chain challenges, which are reducing the profitability of manufacturers.

The forecast for renewable capacity additions in Europe has been revised upwards by 40% from before Russia’s invasion of Ukraine, which led many countries to boost solar and wind uptake to reduce their reliance on Russian natural gas. The growth is driven by high electricity prices that have made small-scale rooftop solar PV systems more financially attractive and by increased policy support in key European markets, especially in Germany, Italy and the Netherlands.

Netherlands' Renewables Drive Putting Pressure On Grid

The Netherlands grid crisis exposes how rapid renewable energy growth is straining transmission capacity. Solar, wind, and electric vehicle demand are overloading networks, forcing officials to urge reduced peak-time power use and accelerate national grid modernization plans.

 

Main Points

The Netherlands grid crisis refers to national electricity congestion caused by surging renewable energy generation and rising consumer demand.

✅ Grid congestion from rapid solar and wind expansion

✅ Strained transmission and distribution capacity

✅ National investment in smart grid upgrades

 

The Dutch government is urging households to reduce electricity consumption between 16:00 and 21:00 — a signal that the country’s once-stable power grid is under serious stress. The call comes amid an accelerating shift to wind and solar power that is overwhelming transmission infrastructure and creating “grid congestion” across regions, as seen in Nordic grid constraints this year.

In a government television campaign, a narrator warns: “When everyone uses electricity at the same time, our power grid can become overloaded. That could lead to failures — so please try to use less electricity between 4 pm and 9 pm.” The plea reflects a system where supply occasionally outpaces the grid’s ability to distribute it, with some regions abroad issuing summer blackout warnings already.

According to Dutch energy firm Eneco’s CEO, Kys-Jan Lamo, the root of the problem lies in the mismatch between modern renewable generation and a grid built for centralized fossil fuel plants. He notes that 70% of Eneco’s output already comes from solar and wind, and this “grid congestion is like traffic on the power lines.” Lamo explains:

“The grid congestion is caused by too much demand in some areas of the network, or by too much supply being pushed into the grid beyond what the network can carry.”

He adds that many of the transmission lines in residential areas are narrow — a legacy of when fewer and larger power plants fed electricity through major feeder lines, underscoring grid vulnerabilities seen elsewhere today. Under the new model, renewable generation occurs everywhere: “This means that electricity is now fed into the grid even in peripheral areas with relatively fine lines — and those lines cannot always cope.”

Experts warn that resolving these issues will demand years of planning and immense investment in smarter grid infrastructure over the coming years. Damien Ernst, an electrical engineering professor at Liège University and respected voice on European grids, states that the Netherlands is experiencing a “grid crisis” brought on by “insufficient investment in distribution and transmission networks.” He emphasizes that the speed of renewable deployment has outpaced the grid’s capacity to absorb it.

Eneco operates a “virtual power plant” control system — described by Lamo as “the brain we run” — that dynamically balances supply and demand. During periods of oversupply, the system can curtail wind turbines or shut down solar panels. Conversely, during peak demand, the system can throttle back electricity provision to participating customers in exchange for lower tariffs. However, these techniques only mitigate strain — they cannot replace the need for physical upgrades or bolster resilience to extreme weather outages alone.

The bottleneck has begun limiting new connections: “Consumers often want to install heat pumps or charge electric vehicles, but they increasingly find it difficult to get the necessary network capacity,” Lamo warns. Businesses too are struggling. “Companies often want to expand operations, but cannot get additional capacity from grid operators. Even new housing developments are affected, since there’s insufficient infrastructure to connect whole communities.”

Currently, thousands of businesses are queuing for network access. TenneT, the national grid operator, estimates that 8,000 firms await initial connection approval, and another 12,000 seek to increase their capacity allocations. Stakeholders warn that unresolved congestion risks choking economic growth.

According to Kys-Jan Lamo: “Looking back, almost all of this could have been prevented.” He acknowledges that post-2015 climate commitments placed heavy emphasis on adding generation and on grid modernization costs more broadly, but “we somewhat underestimated the impact on grid capacity.”

In response, the government has introduced a national “Grid Congestion Action Plan,” aiming to accelerate approvals for infrastructure expansions and to refine regulations to promote smarter grid use. At the same time, feed-in incentives for solar power are being scaled back in some regions, and certain areas may even impose charges to integrate new solar systems into the grid.

The scale of what’s needed is vast. TenneT has proposed adding roughly 100,000 km of new power lines by 2050 and investing in doubling or tripling existing capacity in many areas. However, permit processes can take eight years before construction begins, and many projects require an additional two years to complete. As Lamo points out, “the pace of energy transition far exceeds the grid’s existing capacity — and every new connection request simply extends waiting lists.”

Unless grid expansion keeps up, and as climate pressures intensify, the very clean energy future the Netherlands is striving for may remain constrained by the physics of distribution.

DOE Announces $5 Million to Launch Lithium-Battery Workforce Initiative

DOE Battery Workforce Strategy advances lithium battery manufacturing with DOE, DOL, and AFL-CIO partnerships, pilot training programs, EV supply chain skills, and industry-labor credentials to strengthen clean energy jobs and domestic competitiveness.

 

Key Points

An initiative to fund pilot training and labor-industry partnerships to scale domestic lithium battery manufacturing.

✅ $5M for up to five pilot training programs.

✅ Builds industry-labor credentials across the battery supply chain.

✅ Targets EV manufacturing, recycling, and materials refining.

 

The U.S. Department of Energy (DOE), in coordination with the U.S. Department of Labor and the AFL-CIO, today announced the launch of a national workforce development strategy for lithium-battery manufacturing. As part of a $5 million investment, DOE will support up to five pilot training programs in energy and automotive communities and advance workforce partnerships between industry and labor for the domestic lithium battery supply chain. Lithium batteries power everything from electric vehicles, where U.S. automakers' battery strategies are rapidly evolving, to consumer electronics and are a critical component of President Biden’s whole-of-government decarbonization strategy. This workforce initiative will support the nation’s global competitiveness within battery manufacturing while strengthening the domestic economy and clean energy supply chains. 

“American leadership in the global battery supply chain, as the U.S. works with allies on EV metals to strengthen access, will be based not only on our innovative edge, but also on our skilled workforce of engineers, designers, scientists, and production workers,” said U.S. Secretary of Energy Jennifer M. Granholm, “President Biden has a vision for achieving net zero emissions while creating millions of good paying, union jobs — and DOE’s battery partnerships with labor and industry are key to making that vision a reality.” 

“President Biden has made the creation of good union jobs a cornerstone of his climate strategy,” said AFL-CIO President Liz Shuler. “We applaud DOE for being proactive in pulling labor and management together as the domestic battery industry is being established, and as Canada accelerates EV assembly nearby, we look forward to working with DOE and DOL to develop high-road training standards for the entire battery supply chain.” 

“I am glad to see the Department of Energy collaborating with our industry partners to invest in the next generation of our clean energy workforce,” said U.S. Senator Joe Manchin (D-WV), Chairman of the Senate Energy and Natural Resources Committee. “While I remain concerned about our dependence on China and other foreign countries for key parts of the lithium-ion battery supply chain, and recent lithium supply risks highlight the urgency, engaging our strong and capable workforce to manufacture batteries domestically is a critical step toward reducing our reliance on other countries and ensuring we are able to maintain our energy security. I look forward to seeing this initiative grow, and we will continue to work closely together to ensure we can onshore the rest of the battery supply chain.” 

The pilot training programs will bring together manufacturing companies, organized labor, and training providers to lay the foundation for the development of a broad national workforce strategy. The pilots will support industry-labor cooperation, as major North American projects like the B.C. battery plant advance, and will provide sites for job task analyses and documenting worker competencies. Insights gained will support the development of national industry-recognized credentials and inform the development of broader training programs to support the overall battery supply chain. 

This initiative comes as part of suite of announcements from President Biden’s Interagency Working Group (IWG) on Coal and Power Plant Communities and Economic Revitalization—a partnership among the White House and nearly a dozen federal agencies committed to pursuing near- and long-term actions to support coal, oil and gas, and power plant communities as the nation transitions to a clean energy economy. 

This announcement follows DOE’s recent release of two Notices of Intent authorized by the Bipartisan Infrastructure Law to provide $3 billion to support projects that bolster domestic battery manufacturing and battery recycling for a circular economy efforts nationwide. The funding, which will be made available in the coming months, will support battery-materials refining, which will bolster domestic refining capacity of minerals such as lithium, as well as production plants, battery cell and pack manufacturing facilities, and recycling facilities. 

It also builds on progress the Biden-Harris Administration and DOE have driven to secure a sustainable, reliable domestic supply of critical minerals and materials necessary for clean energy supply chains, including lithium, with emerging sources like Alberta's lithium-rich oil fields underscoring regional potential. This includes $44 million in funding through the DOE Mining Innovations for Negative Emissions Resource Recovery (MINER) program to fund the technology research that increases the mineral yield while decreasing the required energy, and subsequent emissions, to mine and extract critical minerals such as lithium, copper, nickel, and cobalt.
