UK Energy Price Cap Cut 2024 signals relief as wholesale gas prices fall; Ofgem price cap drops per Cornwall Insight, aided by LNG supply, mild winter, despite Red Sea tensions and Ukraine conflict impacts.

 

Key Points

A forecast cut to Great Britain's Ofgem price cap as wholesale gas falls, easing typical annual household bills in 2024.

✅ Cap falls from £1,928 to £1,620 in April 2024

✅ Forecast £1,497 in July, then about £1,541 from October

✅ Drivers: lower wholesale gas, LNG supply, mild winter

 

Households in Great Britain are set to experience a significant reduction in energy costs this spring, with bills projected to drop by over £300 annually. This decrease is primarily due to a decline in wholesale gas prices, offering some respite to those grappling with the cost of living crisis.

Cornwall Insight, a well-regarded industry analyst, predicts a 16% reduction in average bills from the previous quarter, potentially reaching the lowest levels since the onset of the Ukraine conflict.

The industry’s price cap, indicative of the average annual bill for a typical household, is expected to decrease from the current £1,928, set earlier this month, to £1,620 in April – a reduction of £308 and £40 less than previously forecasted in December, as ministers consider ending the gas-electricity price link to improve market resilience.

Concerns about escalating tensions in the Red Sea, where Houthi rebels have disrupted global shipping, initially led analysts to fear an increase in wholesale oil prices and subsequent impact on household energy costs.

Contrary to these concerns, oil prices have remained relatively stable, and European gas reserves have been higher than anticipated during a mild winter, with European gas prices returning to pre-Ukraine war levels since November.

Cornwall Insight anticipates that energy prices will continue to be comparatively low through 2024. They predict a further decline to £1,497 for a typical annual bill from July, followed by a slight increase to £1,541 starting in October.

This forecast is a welcome development for Britons who have been dealing with increased expenses across various sectors, from food to utilities, amidst persistently high inflation rates, with energy-driven EU inflation hitting lower-income households hardest across member states.

Energy bills saw a steep rise in 2021, which escalated further due to the Ukraine conflict in 2022, driving up wholesale gas prices. This surge prompted government intervention to subsidize bills, with the UK price cap estimated to cost around £89bn to the public purse, capping costs to a typical household at £2,500.

Cornwall Insight noted that the supply of liquified natural gas to Europe had not been as adversely affected by the Red Sea disruptions as initially feared. Moreover, the UK has been well-supplied with gas from the US, which has become a more significant supplier since the Ukraine war, even as US electricity prices have risen to multi-decade highs. Contributing factors also include lower gas prices in Asia, mild weather, and robust gas availability.

Craig Lowrey, a principal consultant at Cornwall Insight, remarked that concerns about Red Sea events driving up energy prices have not materialized, allowing households to expect a reduction in prices.

On Monday, the next-month wholesale gas price dropped by 4% to 65p a therm.

However, Lowrey cautioned that a complete return to pre-crisis energy bill levels remains unlikely due to ongoing market impacts from shifting away from Russian energy sources and persistent geopolitical tensions, as well as policy changes such as Britain’s Energy Security Bill shaping market reforms.

Richard Neudegg, director of regulation at Uswitch, welcomed the potential further reduction of the price cap in April. However, he pointed out that this offers little solace to households currently struggling with high winter energy costs during the winter. Neudegg urged Ofgem, the energy regulator, to prompt suppliers to reintroduce more competitive and affordable fixed-price deals.

Lawmakers question FERC licensing process for dams in West Virginia

FERC Hydropower Licensing Dispute centers on FERC authority, Clean Water Act compliance, state water quality certifications, Federal Power Act timelines, and Army Corps dams on West Virginia's Monongahela River licenses.

 

Key Points

An inquiry into FERC's licensing process and state water quality authority for hydropower at Monongahela River dams.

✅ Questions on omitted state water quality conditions

✅ Debate over starting Clean Water Act certification timelines

✅ Potential impacts on states' rights and licensing schedules

 

As federal lawmakers, including Democrats pressing FERC, plan to consider a bill that would expand Federal Energy Regulatory Commission (FERC) licensing authority, questions emerged on Tuesday about the process used by FERC to issue two hydropower licenses for existing dams in West Virginia.

In a letter to FERC Chairman Neil Chatterjee, Democratic leaders of the House Energy and Commerce Committee, as electricity pricing changes were being debated, raised questions about hydropower licenses issued for two dams operated by the U.S. Army Corps of Engineers on the Monongahela River in West Virginia.

U.S. Reps. Frank Pallone Jr. (D-NJ), the ranking member of the Subcommittee on Energy, Bobby Rush (D-IL), the ranking member of the Subcommittee on Environment, and John Sarbanes (D-MD), amid Maryland clean energy enforcement concerns, questioned why FERC did not incorporate all conditions outlined in a West Virginia Department of Environmental Protection water quality certificate into plans for the projects.

“By denying the state its allotted time to review this application and submit requirements on these licenses, FERC is undermining the state’s authority under the Clean Water Act and Federal Power Act to impose conditions that will ensure water quality standards are met,” the letter stated.

The House of Representatives was slated to consider the Hydropower Policy Modernization Act of 2017, H.R. 3043, later in the week. The measure would expand FERC authority over licensing processes, a theme mirrored in Maine's transmission line debate over interstate energy projects. Opponents of the bill argue that the changes would make it more difficult for states to protect their clean water interests.

West Virginia has announced plans to challenge FERC hydropower licenses for the dams on the Monongahela River, echoing Northern Pass opposition seen in New Hampshire.

Melting Glass Experiment Surprises Scientists by Defying a Law of Electricity

Electric Field-Induced Glass Softening reveals a Joule heating anomaly in silicate glass, where anode-side nanoscale alkali depletion drives ionic conduction, localized thermal runaway, melting, and evaporation, challenging homogeneity assumptions and refining materials processing models.

 

Key Points

An effect where electric fields lower glass softening temperature via nanoscale ionic migration and structural change.

✅ Anode-side alkali depletion creates extreme, localized heating

✅ Thermal runaway melts glass near the anode despite uniform bulk

✅ Findings refine Joule heating models and enable new glass processing

 

A team of scientists working with electrical currents and silicate glass have been left gobsmacked after the glass appeared to defy a basic physical law, in a field that also explores electricity-from-air devices for novel energy harvesting.

If you pass an electrical current through a material, the way that current generates heat can be described by Joule's first law. It's been observed time and time again, with the temperature always evenly distributed when the material is homogeneous (or uniform).

But not in this recent experiment. A section - and only a section - of silicate glass became so hot that it melted, and even evaporated. Moreover, it did so at a much lower temperature than the boiling point of the material.

The boiling point of pure silicate glass is 2,230 degrees Celsius (4,046 degrees Fahrenheit). The hottest temperature the researchers recorded in a homogeneous piece of silicate glass during the experiment was 1,868.7 degrees Celsius.

Say whaaaat.

"The calculations did not add up to explain what we were seeing as simply standard Joule heating," said engineer and materials scientist Himanshu Jain of Lehigh University.

"Even under very moderate conditions, we observed fumes of glass that would require thousands of degrees higher temperature than Joule's law could predict!"

Jain and his colleagues from materials science company Corning Incorporated were investigating a phenomenon they had described in a previous paper. In 2015, they reported that an electric field could reduce the temperature at which glass softens, by as much as a few hundred degrees, a line of inquiry that parallels work on low-cost heat-to-electricity materials in energy research. They called this "electric field-induced softening."

 

It was certainly a peculiar phenomenon, so they set up another experiment. They put pieces of glass in a furnace, and applied 100 to 200 volts in the form of both alternating and direct currents.

Next, a thin wisp of vapour emanated from the spot where the anode conveying the current contacted the glass.

"In our experiments, the glass became more than a thousand degrees Celsius hotter near the positive side than in the rest of the glass, which was very surprising considering that the glass was totally homogeneous to begin with," Jain said.

This seems to fly in the face of Joule's first law, so the team investigated more closely - and found that the glass wasn't remaining as homogeneous as it started out. The electric field changed the chemistry and the structure of the glass on nanoscale, in just a small section close to the anode.

This region heats faster than the rest of the glass, to the point of becoming a thermal runaway - where an increase in temperature further increases temperature in a blistering feedback loop.

As it turned out, that spot of structural change and dramatic heat resulted in a small area of glass reaching melting point while the rest of the material remained solid.

"Unlike electronically conducting metals and semiconductors, with time the heating of ionically conducting glass becomes extremely inhomogeneous with the formation of a nanoscale alkali-depletion region, such that the glass melts near the anode, even evaporates, while remaining solid elsewhere," the researchers wrote in their paper.

In other words, the material wasn't homogeneous any more, which means the glass heating experiment doesn't exactly change how we apply Joule's first law.

But it's an exciting result, since until now we didn't know a material could actually lose its homogeneity with the application of an electrical current, with possible implications for thin-film heat harvesters in electronics. (The thing is, no one had tried electrically heating glass to these extreme temperatures before.)

So the physical laws of the Universe are still okay, as a piece of glass hasn't broken them. But Joule's first law may need a bit of tweaking to take this effect into account, a reminder that unconventional energy concepts like nighttime solar cells also challenge our intuitions.

And, of course, it's another piece of understanding that could help us in other ways too, including advances in thermoelectric materials that turn waste heat into electricity.

"Besides demonstrating the need to qualify Joule's law," Jain said, "the results are critical to developing new technology for the fabrication and manufacturing of glass and ceramic materials."

The research has been published in Scientific Reports.

As peak wildfire season nears, SDG&E completes work on microgrid in Ramona

SDG&E Ramona Microgrid delivers renewable energy and battery storage for wildfire mitigation, grid resilience, and PSPS support, powering the Cal Fire Air Attack Base with a 500 kW, 2,000 kWh lithium-ion system during outages.

 

Key Points

A renewable, battery-backed microgrid powering Ramona's Air Attack Base, boosting wildfire response and PSPS resilience.

✅ 500 kW, 2,000 kWh lithium-ion storage replaces diesel

✅ Keeps Cal Fire and USFS aircraft operations powered

✅ Supports PSPS continuity and rural water reliability

 

It figures to be another dry year — with the potential to spark wildfires in the region. But San Diego Gas & Electric just completed a renewable energy upgrade to a microgrid in Ramona that will help firefighters and reduce the effects of power shutoffs to backcountry residents.

The microgrid will provide backup power to the Ramona Air Attack Base, helping keep the lights on during outages, home to Cal Fire and the U.S. Forest Service's fleet of aircrafts that can quickly douse fires before they get out of hand.

"It gives us peace of mind to have backup power for a critical facility like the Ramona Air Attack Base, especially given the fact that fire season in California has become year-round," Cal Fire/San Diego County Fire Chief Tony Mecham said in a statement.

The air attack base serves as a hub for fixed-wing aircraft assigned to put out fires. Cal Fire staffs the base throughout the year with one two airtankers and one tactical aircraft. The base also houses the Forest Service's Bell 205 A++ helicopter and crew to protect the Cleveland National Forest. Aircraft for both CalFire and the Forest Service can also be mobilized to help fight fires throughout the state.

This summer, the Ramona microgrid won't have to rely on diesel generation. Instead, the facility next to the town's airport will be powered by a 500 kilowatt and 2,000 kilowatt-hour lithium-ion battery storage system that won't generate any greenhouse gas emissions.

"What's great about it, besides that it's a renewable resource, is that it's a permanent installation," said Jonathan Woldemariam, SDG&E's director of wildfire mitigation and vegetation management. "In other words, we don't have to roll a portable generator out there. It's something that can be leveraged right there because it's already installed and ready to go."

Microgrids have taken on a larger profile across the state because they can operate independently of the larger electric grid, where repairing California's grid is an ongoing challenge, thus allowing small areas or communities to keep the power flowing for hours at a time during emergencies.

That can be crucial in wildfire-prone areas affected by Public Safety Power Shutoffs, or PSPS, the practice in which investor-owned utilities in California de-energize electrical power lines in a defined area when conditions are dry and windy in order to reduce the risk of a power line falling and igniting a wildfire, while power grid upgrades move forward statewide.

Rural and backcountry communities are particularly hard hit when the power is pre-emptively cut off because many homes rely on water from wells powered by electricity for their homes, horses and livestock.

In addition to Ramona, SDG&E has established microgrids in three other areas in High Fire Threat Districts:

The microgrids in Butterfield Ranch and Shelter Valley run on diesel power but the utility plans to complete solar and battery storage systems for each locale by the end of next year, as other regions develop new microgrid rules to guide deployment.

SDG&E has a fifth microgrid in operation — in Borrego Springs, which in 2013 became the first utility-scale microgrid in the country. It provides grid resiliency to the roughly 2,700 residents of the desert town and serves as a model for integrated microgrid projects elsewhere in delivering local electricity. While the Borrego Springs microgrid is not located in a High Fire Threat District, "when and if any power is turned off, especially the power transmission feed that goes to Borrego, we can support the customers using the microgrid out there," Woldemariam said.

Microgrid costs can be higher than conventional energy systems, even as projected energy storage revenue grows over the next decade, and the costs of the SDG&E projects are passed on to ratepayers. As per California Public Utilities Commission rules, the financial details for each of microgrid are kept confidential for at least three years.

SDG&E's microgrids are part of the utility's larger plan to reduce wildfire risk that SDG&E files with the utilities commission. In its wildfire plan for 2020 through 2022, SDG&E expected to spend $1.89 billion on mitigation measures.

NY Governor Cuomo Announces Green New Deal Included in 2019 Executive Budget

New York Green New Deal accelerates clean energy and climate action, targeting carbon neutrality with renewable energy, offshore wind, solar, energy storage, and green jobs while advancing environmental justice and economy-wide decarbonization.

 

Key Points

New York's plan for 100% clean power by 2040 and 70% renewables by 2030, with a just transition and green jobs.

✅ 100% carbon-free electricity by 2040; 70% renewables by 2030

✅ 9,000 MW offshore wind and 3,000 MW energy storage targets

✅ Just transition focuses on jobs, equity, and affordability

 

New York Governor Andrew M. Cuomo announced the Green New Deal, a nation-leading clean energy and jobs agenda that will aggressively put New York State on a path to net-zero electricity and economy-wide carbon neutrality, is included in the 2019 Executive Budget. The landmark plan provides for a just transition to clean energy that spurs growth of the green economy and prioritizes the needs of low- to moderate-income New Yorkers.

"Climate change is a reality, and the consequences of delay are a matter of life and death. We know what we must do. Now we have to have the vision, the courage, and the competence to get it done," Governor Cuomo said. "While the federal government shamefully ignores the reality of climate change and fails to take meaningful action, we are launching the first-in-the-nation Green New Deal to seize the potential of the clean energy economy, set nation's most ambitious goal for carbon-free power, and ultimately eliminate our entire carbon footprint."

During Governor Cuomo's first two terms, New York banned fracking of natural gas, committed to phasing out coal power by 2020, mandated 50 percent renewable power by 2030, and established the U.S. Climate Alliance to uphold the Paris Agreement, reflecting the view that decarbonization is irreversible under a clean energy economy. Under the Reforming the Energy Vision agenda, New York has held the largest renewable energy procurements in U.S. history, solar has increased nearly 1,500 percent, and offshore wind is poised to transform the State's electricity supply to be cleaner and more sustainable. Through Governor Cuomo's Green New Deal, New York will take the bold next steps to secure a clean energy future that protects the environment for generations to come while growing the clean energy economy.

 

100 Percent Clean Power by 2040 Coupled with New Nation-leading Renewable Energy Mandates

The Green New Deal will statutorily mandate New York's power be 100 percent carbon-free by 2040, the most aggressive goal in the United States and five years ahead of a target recently adopted by California state policymakers. The cornerstone of this new mandate is a significant increase of New York's successful Clean Energy Standard mandate from 50 percent to 70 percent renewable electricity by 2030. This globally unprecedented ramp-up of renewable energy will include:

  • Quadrupling New York's offshore wind target to 9,000 megawatts by 2035, up from 2,400 megawatts by 2030
  • Doubling distributed solar deployment to 6,000 megawatts by 2025, up from 3,000 megawatts by 2023
  • More than doubling new large-scale land-based wind and solar resources through the Clean Energy Standard
  • Maximizing the contributions and potential of New York's existing renewable resources
  • Deploying 3,000 megawatts of energy storage by 2030, up from 1,500 megawatts by 2025
  • Develop an Implementation Plan to Make New York Carbon Neutral

The Green New Deal will create the State's first statutory Climate Action Council, comprised of the heads of relevant State agencies and other workforce, environmental justice, and clean energy experts to develop a comprehensive plan to make New York carbon neutral by significantly and cost-effectively reducing emissions from all major sources, including electricity, transportation, buildings, industry, commercial activity, and agriculture. The Climate Action Council will consider a range of possible options, including the feasibility of working with the U.S. Climate Alliance to create a new multistate emissions reduction program that covers all sectors of the economy, including transportation and industry, and exploring ways to leverage the successful Regional Greenhouse Gas Initiative to drive transformational investment in the clean energy economy and support a just transition.

At the national level, a historic climate deal is reshaping incentives and standards for clean energy deployment across the country.

The Green New Deal will also include an ambitious strategy to move New York's statewide building stock to carbon neutrality. The agenda includes:

Advancing legislative changes to strengthen building energy codes and establish appliance efficiency standards

Directing State agencies to ensure that their facilities uphold the strongest energy efficiency and sustainability standards

Developing a Net Zero Roadmap to chart a course to statewide carbon neutrality in buildings

A Multibillion Dollar Green New Deal Investment in the Clean Tech Economy that will Reduce Greenhouse Gas Emissions

Demonstrating New York's immediate commitment to implementing the nation's most ambitious clean energy agenda and creating high-quality clean energy jobs, Governor Cuomo is announcing $1.5 billion in competitive awards to support 20 large-scale solar, wind and energy storage projects across upstate New York. These investments will add over 1,650 megawatts of capacity and generate over 3,800,000 megawatt-hours of renewable energy annually - enough to power nearly 550,000 homes and create over 2,600 short and long-term jobs. Combined with the renewable energy projects previously announced under the Clean Energy Standard, New York has now awarded more than $2.9 billion to 46 projects statewide, enough to power over one million households.

The Green New Deal also includes new investments to jumpstart New York's offshore wind energy industry and support the State's world-leading target of 9,000 megawatts by 2035. New York will invest up to $200 million in port infrastructure to match private sector investment in regional development of offshore wind. This multi-location investment represents the nation's largest infrastructure commitment to offshore wind and solidifies New York's position as the hub of the burgeoning U.S. offshore wind industry.

These new investments build upon a $250 million commitment to electric vehicle infrastructure by the New York Power Authority's EVolve program, $3.5 billion in private investment in distributed solar driven by NYSERDA's NY-Sun program, and NY Green Bank transactions mobilizing nearly $1.75 billion in private capital for clean energy projects.

 

A Just Transition to a Clean Energy Economy

Deliver Climate Justice for Underserved Communities: The Green New Deal will help historically underserved communities prepare for a clean energy future and adapt to climate change by:

Giving communities a seat at the table by codifying the Environmental Justice and Just Transition Working Group into law and incorporating it into the planning process for the Green New Deal's implementation.

Directing the State's low-income energy task force to identify reforms to achieve greater impact of the public energy funds expended each year in order to increase the effect of funds and initiatives that target energy affordability to underserved communities.

Directing each of the State's ten Regional Economic Development Councils to develop an environmental justice strategy for their region.

Finance a Property Tax Compensation Fund to Help Communities Transition to the Clean Energy Economy: Governor Cuomo is introducing legislation to finance the State's $70 million Property Tax Compensation Fund to continue helping communities directly affected by the transition away from dirty and obsolete energy industries and toward the new clean energy economy. Specifically, this funding will protect communities impacted by the retirement of conventional power generation facilities.

Protect Labor Rights: To ensure creation of high-quality clean energy jobs, large-scale renewable energy projects supported by the Green New Deal will require prevailing wage, and the State's offshore wind projects will be supported by a requirement for a Project Labor Agreement.

Develop the Clean Tech Workforce: To prepare New York's workforce for the transition, New York State will take new steps to support workforce development, including establishing a New York State Advisory Council on Offshore Wind Economic and Workforce Development, as well as investing in an offshore wind training center that will provide New Yorkers with the skills and safety training required to construct this clean energy technology in New York.   

Richard Kauffman, Chairman of Energy and Finance for New York, said, "Governor Cuomo's Green New Deal will advance New York State further into the clean energy future, and we won't let the Trump Administration push us backwards. Governor Cuomo's new commitments ensure New York is the undisputed national clean energy and climate leader, and we will continue to build upon the foundations of the REV agenda to achieve a sustainable economy and healthy environment for generations of New Yorkers to come."

Alicia Barton, President and CEO, NYSERDA, said, "Climate scientists have made frighteningly clear that averting the worst effects of climate change will require bold action, not incremental steps, and Governor Cuomo's Green New Deal boldly goes where no others have before. His unwavering climate agenda includes the most aggressive clean energy target in U.S. history, the largest commitments to renewable energy and to offshore wind in the nation, a massive mobilization of clean energy jobs and an unprecedented investment in offshore wind port infrastructure. Together these actions make New York the clear national leader in the fight against climate change, and will show the world that New York can and will achieve a clean energy future for the sake of future generations."

DEC Commissioner Basil Seggos said, "The threat of climate change calls for bold action like Governor Cuomo's comprehensive agenda to make New York State carbon neutral. The Green New Deal ensures New York is continuing our nation-leading efforts to capitalize on the economic potential of the clean energy economy, while making sure those most vulnerable to climate change are benefitting from the state's efforts and investments. I look forward to working with my agency and authority partners on the Climate Action Council to develop and implement meaningful solutions to reduce greenhouse gas emissions from all sectors of our economy."  

John B. Rhodes, CEO, Department of Public Service, said, "With this nation-leading Green New Deal, Governor Cuomo puts New York on the path to fully clean electricity and to carbon neutrality with the strongest renewable energy goals in the nation. This will deliver the energy system that New York needs - cost-effective, reliable, and 100% clean.”

National Grid warns of short supply of electricity over next few days

National Grid power supply warning highlights electricity shortage risks amid low wind output, generator outages, and cold weather, reducing capacity margins and grid stability; considering demand response and reserve power to avoid blackout risk.

 

Key Points

An alert that reduced capacity from low wind and outages requires actions to maintain UK grid stability.

✅ Low wind output and generator outages reduce capacity margins

✅ ESO exploring demand response and reserve generation options

✅ Aim: maintain grid stability and avoid blackout risk

 

National Grid has warned that Britain’s electricity will be in short supply over the next few days after a string of unplanned power plant outages and unusually low wind speeds this week, as cheap wind power wanes across the system.

The electricity system operator said it will take action to “make sure there is enough generation” during the cold weather spell, including virtual power plants and other demand-side measures, to prevent a second major blackout in as many years.

“Unusually low wind output coinciding with a number of generator outages means the cushion of spare capacity we operate the system with has been reduced,” the company told its Twitter followers.

“We’re exploring measures and actions to make sure there is enough generation available to increase our buffer of capacity.”

A spokeswoman for National Grid said the latest electricity supply squeeze was not expected to be as severe as recorded last month, following reports that the government’s emergency energy plan was not going ahead, and added that the company did not expect to issue an official warning in the next 24 hours.

“We’re monitoring how the situation develops,” she said.

The warning is the second from the electricity system operator in recent weeks. In mid-September the company issued an official warning to the electricity market as peak power prices climbed, that its ‘buffer’ of power reserves had fallen below 500MW and it may need to call on more power plants to help prevent a blackout. The notice was later withdrawn.

Concerns over National Grid’s electricity supplies have been relatively rare in recent years. It was forced in November 2015 to ask businesses to cut their demand as a “last resort” measure to keep the lights on after a string of coal plant breakdowns.

But since then, National Grid’s greater challenge has been an oversupply of electricity, partly due to record wind generation, which has threatened to overwhelm the grid during times of low electricity demand.

National Grid has already spent almost £1bn on extra measures to prevent blackouts over the first half of the year by paying generators to produce less electricity during the coronavirus lockdown, as daily demand fell.

The company paid wind farms to turn off, and EDF Energy to halve the nuclear generation from its Sizewell B nuclear plant, to avoid overwhelming the grid when demand for electricity fell by almost a quarter from last year.

The electricity supply squeeze comes a little over a year after National Grid left large parts of England and Wales without electricity after the biggest blackout in a decade left a million homes in the dark. National Grid blamed a lightning strike for the widespread power failure.

Similar supply strains have recently caused power cuts in China, underscoring how weather and generation mix can trigger blackouts.

Wartsila to Power USA’s First Battery-Electric High-Speed Ferries

San Francisco Battery-Electric Ferries will deliver zero-emission, high-speed passenger service powered by Wartsila electric propulsion, EPMS, IAS, batteries, and shore power, advancing maritime decarbonization under the REEF program and USCG Subchapter T standards.

 

Key Points

They are the first US zero-emission high-speed passenger ferries using integrated electric propulsion and shore power

✅ Dual 625 kW motors enable up to 24-knot service speeds

✅ EPMS, IAS, DC hub, and shore power streamline operations

✅ Built to USCG Subchapter T for safety and compliance

 

Wartsila, a global leader in sustainable marine technology, has been selected to supply the electric propulsion system for the United States' first fully battery-electric, zero-emission high-speed passenger ferries. This significant development marks a pivotal step in the decarbonization of maritime transport, aligning with California's ambitious environmental goals, including recent clean-transport investments across ports and corridors.

A Leap Toward Sustainable Maritime Transport

The project, commissioned by All American Marine (AAM) on behalf of San Francisco Bay Ferry, involves the construction of three 150-passenger ferries, reflecting broader U.S. advances like the Washington State Ferries hybrid upgrade now underway. These vessels will operate on new routes connecting the rapidly developing neighborhoods of Treasure Island and Mission Bay to downtown San Francisco. The ferries are part of the Rapid Electric Emission Free (REEF) Ferry Program, a comprehensive initiative by San Francisco Bay Ferry to transition its fleet to zero-emission propulsion technology. The first vessel is expected to join the fleet in early 2027.

Wärtsilä’s Role in the Project

Wärtsilä's involvement encompasses the supply of a comprehensive electric propulsion system, including the Energy and Power Management System (EPMS), integrated automation system (IAS), batteries, DC hub, transformers, electric motors, and shore power supply. This extensive scope underscores Wärtsilä’s expertise in providing integrated solutions for emission-free marine transportation. The company's extensive global experience in developing and supplying integrated systems and solutions for zero-emission high-speed vessels, as seen with electric ships on the B.C. coast operating today, was a key consideration in the selection process.

Technical Specifications of the Ferries

The ferries will be 100 feet (approximately 30 meters) in length, with a beam of 26 feet and a draft of 5.9 feet. Each vessel will be powered by dual 625-kilowatt electric motors, enabling them to achieve speeds of up to 24 knots. The vessels will be built to U.S. Coast Guard Subchapter T standards, ensuring compliance with stringent safety regulations.

Environmental and Operational Benefits

The transition to battery-electric propulsion offers numerous environmental and operational advantages. Electric ferries produce zero emissions during operation, as demonstrated by Berlin's electric ferry deployments, significantly reducing the carbon footprint of maritime transport. Additionally, electric propulsion systems are generally more efficient and require less maintenance compared to traditional diesel engines, leading to lower operational costs over the vessel's lifespan.

Broader Implications for Maritime Decarbonization

This project is part of a broader movement toward sustainable maritime transport in the United States. San Francisco Bay Ferry has also approved the purchase of two larger 400-passenger battery-electric ferries for transbay routes, further expanding its commitment to zero-emission operations. The agency has secured approximately $200 million in funding from local, state, and federal sources, echoing infrastructure bank support seen in B.C., to support these initiatives, including vessel construction and terminal electrification.

Wartsila’s involvement in this project highlights the company's leadership in the maritime industry's transition to sustainable energy solutions, including hybrid-electric pathways like BC Ferries' new hybrids now in service. With a proven track record in supplying integrated systems for zero-emission vessels, Wärtsilä is well-positioned to support the global shift toward decarbonized maritime transport.

As the first fully battery-electric high-speed passenger ferries in the United States, these vessels represent a significant milestone in the journey toward sustainable and environmentally responsible maritime transportation, paralleling regional advances such as the Kootenay Lake electric-ready ferry entering service. The collaboration between Wärtsilä, All American Marine, and San Francisco Bay Ferry exemplifies the collective effort required to realize a zero-emission future for the maritime industry.

The deployment of these battery-electric ferries in San Francisco Bay not only advances the city's environmental objectives but also sets a precedent for other regions to follow. With continued innovation and collaboration, the maritime industry can look forward to a future where sustainable practices are the standard, not the exception.
