“Shockingly high” numbers of bird and bat deaths caused by one of Canada’s biggest wind farms should serve as a warning to planners of other projects that may be built in crucial wildlife zones, one of the country’s key conservation groups says.

The 86 huge turbines on Wolfe Island, just outside Kingston, Ont., began to produce power about a year ago, and an on-going count of bird and bats that have been killed by the blades has been conducted since then.

A consultantÂ’s report covering the period between July and December of 2009 was released recently, indicating that 602 birds and 1,270 bats were killed by the turbines over that stretch. While the report says the numbers of dead birds and bats are similar to other wind farms in North America, Ottawa-based environmental advocacy group Nature Canada says the figures are actually surprisingly large and represent a significant threat to several endangered species.

“The monitoring reveals shockingly high numbers of fatalities of both birds and bats,” said Ted Cheskey, manager of bird conservation programs at Nature Canada. He said the figures underline what his organization has been arguing all along, that “there should not be wind turbines put in important bird areas or migratory corridors.”

The Wolfe Island fatality rate was about seven birds per turbine over the six-month period. Studies across North America show rates generally ranging from about 0.5 to about eight per year, but there is no number that is consider “normal.”

Mr. Cheskey said Wolfe Island is an internationally recognized “important bird area,” or IBA, for raptors – birds of prey such as owls and hawks that hunt for small mammals to eat. The numbers of those birds killed is worrying, he said, as is the mortality of swallows, which are in decline across Ontario.

The hundreds of bats killed is also cause for “grave concern,” he said, especially because they are less well understood than birds. “They are being massacred [and] we could be driving more species to extinction without understanding how or why.”

Nature Canada is not opposed to wind energy in general, Mr. Cheskey said, but it wants turbines sited to avoid disruption to wildlife. The organization has concerns about planned projects in Prince Edward County and near Point Pelee in Ontario, in southern Quebec, and near Medicine Hat in Alberta. All are regions with endangered bird habitats.

“We should not be putting these farms in places where the risk is going to be high,” he said. “It is a disaster that we can see coming.” At the very least, turbines should be shut down at certain times of year to reduce bird kills, he added.

TransAlta Corp., the Alberta-based energy giant that owns the Wolfe Island wind farm, insists that the death rates for birds and bats are within industry norms. “We are consistent with, or in many cases, below the levels seen elsewhere, whether it be eastern New York, North America or Ontario,” said Scott Hossie, TransAlta’s manager of environmental services for Eastern Canada.

Robert Hornung, president of the Canadian Wind Energy Association, an industry lobby group, said data gathered from wind farms generally shows bird mortality is relatively low, especially compared to the numbers killed when birds fly into high-rise buildings or because of climate change.

Bill Evans, an ornithologist in Ithaca, N.Y., who has reviewed the Wolfe Island report, said it is difficult to come to a firm conclusion about bird mortality at the site because only a half-year of data has been collected.

However, he said “Nature Canada’s stance is probably right” because the initial data does show high levels of deaths. Mr. Evans said the seven birds per turbine that were killed in the six-month study period is the second highest number he’s seen for any wind farm in North America. A full year of data will help clarify the picture, he said.

The government agencies that received the Wolfe Island bird-kill report have been cautious in their responses, indicating they want to see more data before coming to any conclusions. Still, in a letter to TransAlta, an official of the Ontario Ministry of Natural Resources noted that the number of raptors and vultures killed at Wolfe Island were “among the highest” of any wind farm in the province. An Environment Canada official told TransAlta that the death rate among raptors “merits continued, close monitoring in the future.”

Three Mile Island at center of energy debate: Let struggling nuclear plants close or save them

Three Mile Island Nuclear Debate spotlights subsidies, carbon pricing, wholesale power markets, grid reliability, and zero-emissions goals as Pennsylvania weighs keeping Exelon's reactor open amid natural gas competition and flat electricity demand.

 

Key Points

Debate over subsidies, carbon pricing, and grid reliability shaping Three Mile Island's zero-emissions future.

✅ Zero emissions credits vs market integrity

✅ Carbon pricing to value clean baseload power

✅ Closure risks jobs, tax revenue, and reliability

 

Three Mile Island is at the center of a new conversation about the future of nuclear energy in the United States nearly 40 years after a partial meltdown at the Central Pennsylvania plant sparked a national debate about the safety of nuclear power.

The site is slated to close in just two years, a closure plan Exelon has signaled, unless Pennsylvania or a regional power transmission operator delivers some form of financial relief, says Exelon, the Chicago-based power company that operates the plant.

That has drawn the Keystone State into a growing debate: whether to let struggling nuclear plants shut down if they cannot compete in the regional wholesale markets where energy is bought and sold, or adopt measures to keep them in the business of generating power without greenhouse gas emissions.

""The old compromise — that in order to have a reliable, affordable electric system you had to deal with a significant amount of air pollution — is a compromise our new customers today don't want to hear about.""
-Joseph Dominguez, Exelon executive vice president
Nuclear power plants produce about two-thirds of the country's zero-emissions electricity, a role many view as essential to net-zero emissions goals for the grid.

The debate is playing out as some regions consider putting a price on planet-warming carbon emissions produced by some power generators, which would raise their costs and make nuclear plants like Three Mile Island more viable, and developments such as Europe's nuclear losses highlight broader energy security concerns.

States that allow nuclear facilities to close need to think carefully because once a reactor is powered down, there's no turning back, said Jake Smeltz, chief of staff for Pennsylvania State Sen. Ryan Aument, who chairs the state's Nuclear Energy Caucus.

"If we wave goodbye to a nuclear station, it's a permanent goodbye because we don't mothball them. We decommission them," he told CNBC.

Three Mile Island's closure would eliminate more than 800 megawatts of electricity output. That's roughly 10 percent of Pennsylvania's zero-emissions energy generation, by Exelon's calculation. Replacing that with fossil fuel-fired power would be like putting roughly 10 million cars on the road, it estimates.

A closure would also shed about 650 well-paying jobs, putting the just transition challenge in focus for local workers and communities, tied to about $60 million in wages per year. Dauphin County and Londonderry Township, a rural area on the Susquehanna River where the plant is based, stand to lose $1 million in annual tax revenue that funds schools and municipalities. The 1,000 to 1,500 workers who pack local hotels, stores and restaurants every two years for plant maintenance would stop visiting.

Pennsylvanians and lawmakers must now decide whether these considerations warrant throwing Exelon a lifeline. It's a tough sell in the nation's second-largest natural gas-producing state, which already generates more energy than it uses. And time is running out to reach a short-term solution.

"What's meaningful to us is something where we could see the results before we turn in the keys, and we turn in the keys the third quarter of '19," said Joseph Dominguez, Exelon's executive vice president for governmental and regulatory affairs and public policy.

The end of the nuclear age?

The problem for Three Mile Island is the same one facing many of the nation's 60 nuclear plants: They are too expensive to operate.

Financial pressure on these facilities is mounting as power demand remains stagnant due to improved energy efficiency, prices remain low for natural gas-fired generation and costs continue to fall for wind and solar power.

Three Mile Island is something of a special case: The 1979 incident left only one of its two reactors operational, but it still employs about as many people as a plant with two reactors, making it less efficient. In the last three regional auctions, when power generators lock in buyers for their future energy generation, no one bought power from Three Mile Island.

But even dual-reactor plants are facing existential threats. FirstEnergy Corp's Beaver Valley will sell or close its nuclear plant near the Pennsylvania-Ohio border next year as it exits the competitive power-generation business, and facilities like Ohio's Davis-Besse illustrate what's at stake for the region.

Five nuclear power plants have shuttered across the country since 2013. Another six have plans to shut down, and four of those would close well ahead of schedule. An analysis by energy research firm Bloomberg New Energy Finance found that more than half the nation's nuclear plants are facing some form of financial stress.

Today's regional energy markets, engineered to produce energy at the lowest cost to consumers, do not take into account that nuclear power generates so much zero-emission electricity. But Dominguez, the Exelon vice president, said that's out of step with a world increasingly concerned about climate change.

"What we see is increasingly our customers are interested in getting electricity from zero air pollution sources," Dominguez said. "The old compromise — that in order to have a reliable, affordable electric system you had to deal with a significant amount of air pollution — is a compromise our new customers today don't want to hear about."

Strange bedfellows

Faced with the prospect of nuclear plant closures, Chicago and New York have both allowed nuclear reactors to qualify for subsidies called zero emissions credits. Exelon lobbied for the credits, which will benefit some of its nuclear plants in those states.

Even though the plants produce nuclear waste, some environmental groups like the Natural Resources Defense Council supported these plans. That's because they were part of broader packages that promote wind and solar power, and the credits for nuclear are not open-ended. They essentially provide a bridge that keeps zero-emissions power from nuclear reactors on the grid as renewable energy becomes more viable.

Lawmakers in Pennsylvania, Ohio and Connecticut are currently exploring similar options. Jake Smeltz, chief of staff to state Sen. Aument, said legislation could surface in Pennsylvania as soon as this fall. The challenge is to get people to consider the attributes of the sources of their electricity beyond just cost, according to Smeltz.

"Are the plants worth essentially saving? That's a social choice. Do they provide us with something that has benefits beyond the electrons they make? That's the debate that's been happening in other states, and those states say yes," he said.

Subsidies face opposition from anti-nuclear energy groups like Three Mile Island Alert, as well as natural gas trade groups and power producers who compete against Exelon by operating coal and natural gas plants.

"Where we disagree is to have an out-of-market subsidy for one specific company, for a technology that is now proven and mature in our view, at the expense of consumers and the integrity of competitive markets," NRG Energy Mauricio Gutierrez told analysts during a conference call this month.

Smeltz notes that power producers like NRG would fill in the void left by nuclear plants as they continue to shut down.

"The question that I think folks need to answer is are these programs a bailout or is the opposition to the program a payout? Because at the end of the day someone is going to make money. The question is who and how much?" Smeltz said.

Changing the market

Another critic is PJM Interconnection, the regional transmission organization that operates the grid for 13 states, including Pennsylvania, and Washington, D.C.

The subsidies distort price formation and inject uncertainty into the markets, says Stu Bresler, senior vice president in charge of operations and markets at PJM.

The danger PJM sees is that each new subsidy creates a precedent for government intervention. The uncertainty makes it harder for investors to determine what sort of power generation is a sound investment in the region, Bresler explained. Those investors could simply decide to put their capital to work in other energy markets where the regulatory outlook is more stable, ultimately leading to underinvestment in places where government intervenes, he added.

PJM believes longer-term, regional approaches are more appropriate. It has produced research that outlines how coal plants and nuclear energy, which provide the type of stable energy that is still necessary for reliable power supply, could play a larger role in setting prices. It is also preparing to release a report on how to put a price on carbon emissions in all or parts of the regional grid.

"If carbon emissions are the concern and that is the public policy issue with which policymakers are concerned, the simple be-all answer from a market perspective is putting a price on carbon," Bresler said.

Three Mile Island could be viable if natural gas prices rose from below $3 per million British thermal units to about $5 per mmBtu and if a "reasonable" price were applied to carbon, according to Exelon's Dominguez. He is encouraged by the fact that conversations around new pricing models and carbon pricing are gaining traction.

"The great part about this is everybody understands we have a major problem. We're losing some of the lowest-cost, cleanest and most reliable resources in America," Dominguez said.

Was there another reason for electricity shutdowns in California?

PG&E Wind Shutdown and Renewable Reliability examines PSPS strategy, wildfire risk, transmission line exposure, wind turbine cut-out speeds, grid stability, and California's energy mix amid historic high-wind events and supply constraints across service areas.

 

Key Points

An overview of PG&E's PSPS decisions, wildfire mitigation, and how wind cut-out limits influence grid reliability.

✅ Wind turbines reach cut-out near 55 mph, reducing generation.

✅ PSPS mitigates ignition from damaged transmission infrastructure.

✅ Baseload diversity improves resilience during high-wind events.

 

According to the official, widely reported story, Pacific Gas & Electric (PG&E) initiated power shutoffs across substantial portions of its electric transmission system in northern California as a precautionary measure.

Citing high wind speeds they described as “historic,” the utility claims that if it didn’t turn off the grid, wind-caused damage to its infrastructure could start more wildfires.

Perhaps that’s true. Perhaps. This tale presumes that the folks who designed and maintain PG&E’s transmission system are unaware of or ignored the need to design it to withstand severe weather events, and that the Federal Energy Regulatory Commission (FERC) and North American Electric Reliability Corp. (NERC) allowed the utility to do so.

Ignorance and incompetence happens, to be sure, but there’s much about this story that doesn’t smell right—and it’s disappointing that most journalists and elected officials are apparently accepting it without question.

Take, for example, this statement from a Fox News story about the Kincade Fires: “A PG&E meteorologist said it’s ‘likely that many trees will fall, branches will break,’ which could damage utility infrastructure and start a fire.”

Did you ever notice how utilities cut wide swaths of trees away when transmission lines pass through forests? There’s a reason for that: When trees fall and branches break, the grid can still function, and even as the electric rhythms of New York City shifted during COVID-19, operators planned for variability.

So, if badly designed and poorly maintained infrastructure isn’t the reason PG&E cut power to millions of Californians, what might have prompted them to do so? Could it be that PG&E’s heavy reliance on renewable energy means they don’t have the power to send when a “historic” weather event occurs, especially as policymakers weigh the postponed closure of three power plants elsewhere in California?

 

Wind Speed Limits

The two most popular forms of renewable energy come with operating limitations, which is why some energy leaders urge us to keep electricity options open when planning the grid. With solar power, the constraint is obvious: the availability of sunlight. One doesn’t generate solar power at night and energy generation drops off with increasing degrees of cloud cover during the day.

The main operating constraint of wind power is, of course, wind speed, and even in markets undergoing 'transformative change' in wind generation, operators adhere to these technical limits. At the low end of the scale, you need about a 6 or 7 miles-per-hour wind to get a turbine moving. This is called the “cut-in speed.” To generate maximum power, about a 30 mph wind is typically required. But, if the wind speed is too high, the wind turbine will shut down. This is called the “cut-out speed,” and it’s about 55 miles per hour for most modern wind turbines.

It may seem odd that wind turbines have a cut-out speed, but there’s a very good reason for it. Each wind turbine rotor is connected to an electric generator housed in the turbine nacelle. The connection is made through a gearbox that is sized to turn the generator at the precise speed required to produce 60 Hertz AC power.

The blades of the wind turbine are airfoils, just like the wings of an airplane. Adjusting the pitch (angle) of the blades allows the rotor to maintain constant speed, which, in turn, allows the generator to maintain the constant speed it needs to safely deliver power to the grid. However, there’s a limit to blade pitch adjustment. When the wind is blowing so hard that pitch adjustment is no longer possible, the turbine shuts down. That’s the cut-out speed.

Now consider how California’s power generation profile has changed. According to Energy Information Administration data, the state generated 74.3 percent of its electricity from traditional sources—fossil fuels and nuclear, amid debates over whether to classify nuclear as renewable—in 2001. Hydroelectric, geothermal, and biomass-generated power accounted for most of the remaining 25.7 percent, with wind and solar providing only 1.98 percent of the total.

By 2018, the state’s renewable portfolio had jumped to 43.8 percent of total generation, with clean power increasing and wind and solar now accounting for 17.9 percent of total generation. That’s a lot of power to depend on from inherently unreliable sources. Thus, it wouldn’t be at all surprising to learn that PG&E didn’t stop delivering power out of fear of starting fires, but because it knew it wouldn’t have power to deliver once high winds shut down all those wind turbines

Experts Advise Against Cutting Quebec's Energy Exports Amid U.S. Tariff War

Quebec Hydropower Export Retaliation examines using electricity exports to counter U.S. tariffs amid Canada-U.S. trade tensions, weighing clean energy supply, grid reliability, energy security, legal risks, and long-term market impacts.

 

Key Points

Using Quebec electricity exports as leverage against U.S. tariffs, and its economic, legal, and diplomatic consequences.

✅ Revenue loss for Quebec and higher costs for U.S. consumers

✅ Risk of legal disputes under trade and energy agreements

✅ Long-term erosion of market share and grid cooperation

 

As trade tensions between Canada and the United States continue to escalate, with electricity exports at risk according to recent reporting, discussions have intensified around potential Canadian responses to the imposition of U.S. tariffs. One of the proposals gaining attention is the idea of reducing or even halting the export of energy from Quebec to the U.S. This measure has been suggested by some as a potential countermeasure to retaliate against the tariffs. However, experts and industry leaders are urging caution, emphasizing that the consequences of such a decision could have significant economic and diplomatic repercussions for both Canada and the United States.

Quebec plays a critical role in energy trade, particularly in supplying hydroelectric power to the United States, especially to the northeastern states, including New York where tariffs may spike energy prices according to analysts, strengthening the case for stable cross-border flows. This energy trade is deeply embedded in the economic fabric of both regions. For Quebec, the export of hydroelectric power represents a crucial source of revenue, while for the U.S., it provides access to a steady and reliable supply of clean, renewable energy. This mutually beneficial relationship has been a cornerstone of trade between the two countries, promoting economic stability and environmental sustainability.

In the wake of recent U.S. tariffs on Canadian goods, some policymakers have considered using energy exports as leverage, echoing threats to cut U.S. electricity exports in earlier disputes, to retaliate against what is viewed as an unfair trade practice. The idea is to reduce or stop the flow of electricity to the U.S. as a way to strike back at the tariffs and potentially force a change in U.S. policy. On the surface, this approach may appear to offer a viable means of exerting pressure. However, experts warn that such a move would be fraught with significant risks, both economically and diplomatically.

First and foremost, Quebec's economy is heavily reliant on revenue from hydroelectric exports to the U.S. Any reduction in these energy sales could have serious consequences for the province's economic stability, potentially resulting in job losses and a decrease in investment. The hydroelectric power sector is a major contributor to Quebec's GDP, and recent events, including a tariff threat delaying a green energy bill in Quebec, illustrate how trade tensions can ripple through the policy landscape, while disrupting this source of income could harm the provincial economy.

Additionally, experts caution that reducing energy exports could have long-term ramifications on the energy relationship between Quebec and the northeastern U.S. These two regions have developed a strong and interconnected energy network over the years, and abruptly cutting off the flow of electricity could damage this vital partnership. Legal challenges could arise under existing trade agreements, and even as tariff threats boost support for Canadian energy projects among some stakeholders, the situation would grow more complex. Such a move could also undermine trust between the two parties, making future negotiations on energy and other trade issues more difficult.

Another potential consequence of halting energy exports is that U.S. states may seek alternative sources of energy, diminishing Quebec's market share in the long run. As the U.S. has a growing demand for clean energy, especially as it looks to transition away from fossil fuels, and looks to Canada for green power in several regions, cutting off Quebec’s electricity could prompt U.S. states to invest in other forms of energy, including renewables or even nuclear power. This could have a lasting effect on Quebec's position in the U.S. energy market, making it harder for the province to regain its footing.

Moreover, reducing or ceasing energy exports could further exacerbate trade tensions, leading to even greater economic instability. The U.S. could retaliate by imposing additional tariffs on Canadian goods or taking other measures that would negatively impact Canada's economy. This could create a cycle of escalating trade barriers that would hurt both countries and undermine the broader North American trade relationship.

While the concept of using energy exports as a retaliatory tool may seem appealing to some, the experts' advice is clear: the potential economic and diplomatic costs of such a strategy outweigh the short-term benefits. Quebec’s role as an energy supplier to the U.S. is crucial to its own economy, and maintaining a stable, reliable energy trade relationship is essential for both parties. Rather than escalating tensions further, it may be more prudent for Canada and the U.S. to seek diplomatic solutions that preserve trade relations and minimize harm to their economies.

While the idea of using Quebec’s energy exports as leverage in response to U.S. tariffs may appear attractive on the surface, and despite polls showing support for tariffs on energy and minerals among Canadians, it carries significant risks. Experts emphasize the importance of maintaining a stable energy export strategy to protect Quebec’s economy and preserve positive diplomatic relations with the U.S. Both countries have much to lose from further escalating trade tensions, and a more measured approach is likely to yield better outcomes in the long run.

Wind and Solar Energy Surpass Coal in U.S. Electricity Generation

Wind and Solar Surpass Coal in U.S. power generation, as EIA data cites falling LCOE, clean energy incentives, grid upgrades, and battery storage driving renewables growth, lower emissions, jobs, and less fossil fuel reliance.

 

Key Points

An EIA-noted milestone where U.S. renewables outproduce coal, driven by lower LCOE, policy credits, and grid upgrades.

✅ EIA data shows wind and solar exceed coal generation

✅ Falling LCOE boosts project viability across the grid

✅ Policies and storage advances strengthen reliability

 

In a landmark shift for the energy sector, wind and solar power have recently surpassed coal in electricity generation in the United States. This milestone, reported by Warp News, marks a significant turning point in the country’s energy landscape and underscores the growing dominance of renewable energy sources.

A Landmark Achievement

The achievement of wind and solar energy generating more electricity than coal is a landmark moment in the U.S. energy sector. Historically, coal has been a cornerstone of electricity production, providing a substantial portion of the nation's power needs. However, recent data reveals a transformative shift, with renewables surpassing coal for the first time in 130 years, as renewable energy sources, particularly wind and solar, have begun to outpace coal in terms of electricity generation.

The U.S. Energy Information Administration (EIA) reported that in recent months, wind and solar combined produced more electricity than coal, including a record 28% share in April, reflecting a broader trend towards cleaner energy sources. This development is driven by several factors, including advancements in renewable technology, decreasing costs, and a growing commitment to reducing greenhouse gas emissions.

Technological Advancements and Cost Reductions

One of the key drivers behind this shift is the rapid advancement in wind and solar technologies, as wind power surges in the U.S. electricity mix across regions. Improvements in turbine and panel efficiency have significantly increased the amount of electricity that can be generated from these sources. Additionally, technological innovations have led to lower production costs, making wind and solar energy more competitive with traditional fossil fuels.

The cost of solar panels and wind turbines has decreased dramatically over the past decade, making renewable energy projects more economically viable. According to Warp News, the levelized cost of electricity (LCOE) from solar and wind has fallen to levels that are now comparable to or lower than coal-fired power. This trend has been pivotal in accelerating the transition to renewable energy sources.

Policy Support and Investment

Government policies and incentives have also played a crucial role in supporting the growth of wind and solar energy, with wind now the most-used renewable electricity source in the U.S. helping drive deployment. Federal and state-level initiatives, such as tax credits, subsidies, and renewable energy mandates, have encouraged investment in clean energy technologies. These policies have provided the financial and regulatory support necessary for the expansion of renewable energy infrastructure.

The Biden administration’s focus on addressing climate change and promoting clean energy has further bolstered the transition. The Infrastructure Investment and Jobs Act and the Inflation Reduction Act, among other legislative efforts, have allocated significant funding for renewable energy projects, grid modernization, and research into advanced technologies.

Environmental and Economic Implications

The surpassing of coal by wind and solar energy has significant environmental and economic implications, building on the milestone when renewables became the second-most prevalent U.S. electricity source in 2020 and set the stage for further gains. Environmentally, it represents a major step forward in reducing carbon emissions and mitigating climate change. Coal-fired power plants are among the largest sources of greenhouse gases, and transitioning to cleaner energy sources is essential for meeting climate targets and improving air quality.

Economically, the shift towards wind and solar energy is creating new opportunities and industries. The growth of the renewable energy sector is generating jobs in manufacturing, installation, and maintenance. Additionally, the decreased reliance on imported fossil fuels enhances energy security and stabilizes energy prices.

Challenges and Future Outlook

Despite the progress, there are still challenges to address. The intermittency of wind and solar power requires advancements in energy storage and grid management to ensure a reliable electricity supply. Investments in battery storage technologies and smart grid infrastructure are crucial for overcoming these challenges and integrating higher shares of renewable energy into the grid.

Looking ahead, the trend towards renewable energy is expected to continue, with renewables projected to soon provide about one-fourth of U.S. electricity as deployment accelerates, driven by ongoing technological advancements, supportive policies, and a growing commitment to sustainability. As wind and solar power become increasingly cost-competitive and efficient, their role in the U.S. energy mix will likely expand, further displacing coal and other fossil fuels.

Conclusion

The surpassing of coal by wind and solar energy in U.S. electricity generation is a significant milestone in the transition to a cleaner, more sustainable energy future. This achievement highlights the growing importance of renewable energy sources and the success of technological advancements and supportive policies in driving this transition. As the U.S. continues to invest in and develop renewable energy infrastructure, the move away from coal represents a crucial step towards achieving environmental goals and fostering economic growth in the clean energy sector.

Mercury in $3 billion takeover bid for Tilt Renewables

Mercury Energy Tilt Renewables acquisition signals a trans-Tasman energy push as PowAR and Mercury split assets via a scheme of arrangement, offering $7.80 per share and a $2.96b valuation across Australia and New Zealand.

 

Key Points

A PowAR-Mercury deal to buy Tilt Renewables, splitting Australian and New Zealand assets via a court-approved scheme.

✅ $7.80 per share, valuing Tilt at $2.96b

✅ PowAR takes AU assets; Mercury gets NZ business

✅ Infratil and Mercury to vote for the scheme

 

Mercury Energy and an Australian partner appear to have won the race to buy Tilt Renewables, an Australasian wind farm developer which was spun out of TrustPower, bidding almost $3 billion, amid wider utility consolidation such as the Peterborough Distribution sale to Hydro One.

Yesterday Tilt Renewables announced that it had entered a scheme implementation agreement under which it was proposed that PowAR would acquire its Australian business and Mercury would acquire the New Zealand business, mirroring cross-border approvals where U.S. antitrust clearance shaped Hydro One's bid for Avista.

Conducted through a scheme of arrangement, Tilt shareholders will be offered $7.80 a share, valuing Tilt at $2.96b.

Yesterday morning shares in Tilt opened about 18 per cent up at $7.65, though regulatory outcomes can swing valuations as seen when Hydro One-Avista reconsideration of a U.S. order came into play.

In early December Infratil, which owns around two thirds of Tilt's shares, announced it was undertaking a review of its investment after receiving approaches, with investor sentiment sensitive to governance shifts as when Hydro One shares fell after leadership changes in Ontario.

According to a report in the Australian Financial Review, the transtasman bid beat out other parties including ASX-listed APA Group, Canadian pension fund CDPQ and Australian fund manager Infrastructure Capital Group, as Canadian investors like Ontario Teachers' Plan pursue similar infrastructure deals.

“This compelling acquisition proposal is a result of Tilt Renewables’ constant focus on delivering long-term value for shareholders and the board is pleased that, with these new owners, the transition to renewables in Australia and New Zealand will continue to accelerate,” Tilt’s chairman Bruce Harker said.

Comparable community-led clean energy partnerships, such as initiatives with British Columbia First Nations highlighted in clean-energy generation, underscore the broader momentum.

Just prior to the announcement, Tilt shares had been trading for less than $4. Such repricing reflects how utilities can face perceived uncertainties, as one investor argued too many unknowns at the time.

Mercury is already Tilt’s second largest shareholder, at just under 20 per cent. Both Infratil and Mercury have agreed to vote in favour of the scheme. The deal values Tilt’s New Zealand business at $770m, however the value of Mercury’s existing shareholding is around $585m, meaning the company will increase debt by around $185m.

Ex-SpaceX engineers in race to build first commercial electric speedboat

Arc One Electric Speedboat delivers zero-emission performance, quiet operation, and reduced maintenance, leveraging battery propulsion, aerospace engineering, and venture-backed innovation to cut noise pollution, fuel costs, and water contamination in high-performance marine recreation.

 

Key Points

Arc One Electric Speedboat is a battery-powered, zero-emission craft offering quiet, high-performance marine cruising.

✅ 475 hp, 24 ft hull, about 40 mph top speed

✅ Cuts noise, fumes, and water contamination vs gas boats

✅ Backed by Andreessen Horowitz; ex-SpaceX engineers

 

A team of former SpaceX rocket engineers have joined the race to build the first commercial electric speedboat.

The Arc Boat company announced it had raised $4.25m (£3m) in seed funding to start work on a 24ft 475-horsepower craft that will cost about $300,000.

The LA-based company, which is backed by venture capital firm Andreessen Horowitz (an early backer of Facebook and Airbnb), said the first model of the Arc One boat would be available for sale by the end of the year.

Mitch Lee, Arc’s chief executive, said he wanted to build electric boats because of the impact conventional petrol- or diesel-powered boats have on the environment.

“They not only get just two miles to the gallon, they also pump a lot of those fumes into the water,” Lee said. “In addition, there is the huge noise pollution factor [of conventional boats] and that is awful for the marine life. With gas-powered boats it’s not just carbon emissions into the air, it’s also polluting the water and causing noise pollution. Electric boats, like electric ships clearing the air on the B.C. coast, eliminate all that.”

Lee said electric vessels would also reduce the hassle of boat ownership. “I love being out on the water, being on a boat is so much fun, but owning a boat is so awful,” he said. “I have always believed that electric boats make sense. They will be quicker, quieter and way cheaper and easier to operate and maintain, with access options like an electric boat club in Seattle lowering barriers for newcomers.”

While the first models will be very expensive, Lee said the cost was mostly in developing the technology and cheaper versions would be available in the future, mirroring advances in electric aviation seen across the industry. “It is very much the Tesla approach – we are starting up market and using that income to finance research and development and work our way down market,” he said.

Lee said the technology could be applied to larger craft, and even ferries could run on electricity in the future, as projects for battery-electric high-speed ferries begin to scale.

“We started in February with no team, no money and no warehouse,” he said. “By December we are going to be selling the Arc One, and we are hiring aggressively because we want to accelerate the adoption of electric boats across a whole range of craft, including an electric-ready ferry on Kootenay Lake.”

Lee founded the company with fellow mechanical engineer Ryan Cook. Cook, the company’s chief technology officer, was previously the lead mechanical engineer at Elon Musk’s space exploration company SpaceX where he worked on the Falcon 9 rocket, the world’s first orbital class reusable rocket. In parallel, Harbour Air's electric aircraft highlights cross-sector electrification. Apart from Lee, all of Arc’s employees have some experience working at SpaceX.

Sweden’s Candela C-7 hydrofoil boat was crowned the fastest electric vessel.
