Officials say Constellation stuck with ruling

Nova Scotia Power Active Demand Control Tariff lets the utility direct Port Hawkesbury Paper load, enabling demand response, efficiency, and industrial electricity rates, while regulators assess impacts on ratepayers, grid reliability, mill viability, and savings.

Key Points

A four-year tariff letting the utility control the mill load for demand response, efficiency, and lower costs.

✅ Utility can increase or reduce daily consumption at the mill

✅ Projected savings of $10M annually for other ratepayers to 2023

✅ Regulators reviewing cost allocation, monitoring, and viability

Nova Scotia Power is scheduled to appear before government regulators Tuesday morning seeking approval for a unique discount rate for its largest customer.

Under the four-year plan, Nova Scotia Power would control the supply of electricity to Port Hawkesbury Paper, a move referenced in a grid operations report that urges changes, with the right to direct the company to increase or reduce daily consumption throughout the year.

The rate proposal is supported by the mill, which says it needs to lower its power bill to keep its operation viable.

The rate went into effect on Jan. 1 on a temporary basis, pending the outcome of a hearing this week before the Nova Scotia Utility and Review Board, amid broader calls for an independent body to lead electricity planning.

The mill accounts for 10 per cent of the provincial electricity load, even as a neighbouring utility pursues more Quebec power for the region, producing glossy paper used in magazines and catalogs.

Nova Scotia Power says controlling how much electricity the mill uses — and when — will allow it to operate the system much more efficiently, as it expands biomass generation initiatives, saving other customers $10 million a year until the rate expires in 2023.

Ceding control 'not an easy decision'
In its opening statement that was filed in advance, Port Hawkesbury Paper said ceding the control of its electrical supply to Nova Scotia Power was "not an easy decision" to make, but the company is confident the arrangement will work.

In September 2019, Nova Scotia Power and the mill jointly applied for an "extra large active demand control tariff," which would provide electricity to the mill for about $61 per megawatt hour, well below the full cost of generating the electricity.

The utility said "fully allocating costs" would result in "prices in excess of $80/MWh ... and [would] not [be] financially viable for the mill."

In its statement, Port Hawkesbury Paper said since the initial filing "there have been greater near term declines in market demand and pricing for PHP's product than was forecast at that time, continuing to put pressure on our business and further highlighting the need to maintain the balance provided for in the new tariff."

Consumer advocate sees 'advantage,' but will challenge
Bill Mahody represents Nova Scotia Power's 400,000 residential customers before the review board. He wants proof the mill will pay enough toward the cost of generating the electricity it uses, amid concerns over biomass use in the province today.

"We filed evidence, as have others involved in the proceeding, that would call into question whether or not the rate design is capturing all of those costs and that will be a significant issue before the board," Mahody said.

Still, he sees value in the proposal.

"This proposed rate gives Nova Scotia Power the ability to control that sizable Port Hawkesbury Paper load to the advantage of other ratepayers, as the province pursues more wind and solar projects, because Nova Scotia Power would be reducing the costs that other ratepayers are going to face," he said.

Mahody is also calling for a mechanism to monitor whether the mill's position actually improves to the point where it could pay higher rates.

"An awful lot can change during a four-year period, with new tidal power projects underway, and I think the board ought to have the ability to check in on this and make sure that their preferential rate continues to be justified," he said.

Major employer
Port Hawkesbury Paper, owned by Stern Partners in Vancouver, has received discounted power rates since it bought the idled mill in 2012. But the "load retention tariff" as it was called, expired at the end of 2019.

Regulators have accepted Nova Scotia Power's argument that it would cost other customers more if the mill ceased to operate.

The mill said it spends between $235 million and $265 million annually, employing 330 people directly and supporting 500 other jobs indirectly.

The Nova Scotia government pledged $124 million in financial assistance as part of the reopening in 2012.

Duke Energy zero-coal 2050 plan outlines a decarbonized energy mix, aligning with Paris goals, cutting greenhouse gas emissions, driven by investor pressure, shifting to natural gas, extending nuclear power, and phasing out coal.

Key Points

An investor-driven scenario to end coal by 2050, shift to natural gas, extend nuclear plants, and manage climate risk.

✅ Eliminates coal from the generation mix by 2050

✅ Prioritizes natural gas transitions without CCS breakthroughs

✅ Extends nuclear plant licenses to limit carbon emissions

One of America’s largest utility companies, Duke Energy, is set to release a report later this month that sketches a drastically changed electricity mix in a carbon-constrained future.

The big picture: Duke is the latest energy company to commit to releasing a report about climate change in response to investor pressure, echoing shifts such as Europe's oil majors going electric across the sector, conveyed by non-binding but symbolically important shareholder resolutions. Duke provides electricity to more than seven million customers in the Carolinas, the Midwest and Florida.

Gritty details: The report is expected to find that coal, currently 33% of Duke’s mix, gone entirely from its portfolio by 2050 in a future scenario where the world has taken steps to cut greenhouse gas emissions, and where global coal-fired electricity use is falling markedly, to a level consistent with keeping global temperatures from rising two degrees Celsius. That’s the big ambition of the 2015 Paris climate deal, but the current commitments aren’t close to reaching that.

What they're saying: “What’s difficult about this is we are trying to overlay what we understand currently about technology,” Lynn Good, Duke CEO, told Axios in an interview on the sidelines of a major energy conference here.

She went on to say that this scenario of zero coal by 2050 doesn’t assume any breakthroughs in technology that captures carbon emissions from coal-fired power plants. “We don’t see that technology today, and we need to make economic decisions to get those units moving and replacing them with natural gas.”

Good also stressed the benefits of its several nuclear power plants, highlighting the role of sustaining U.S. nuclear power in decarbonization, which emit no carbon emissions. She said Duke isn’t considering investing in new nuclear plants, but plans to seek federal relicensing of current plants.

“If I turn them off, the resource that would replace them today is natural gas, so carbon will go up,” Good said. “Our objective is to continue to keep those plants as long as possible.”

What’s next: A spokesman said the other details of their 2050 scenario estimates will be available when the report is officially released by month’s end.

Axios reports that Duke Energy will release a report later this month that detail the utility's efforts to mitigate climate change risks and plan carbon-free electricity investments across its operations. The report includes a scenario that eliminates coal entirely from the company's power mix by 2050. Coal currently makes up about a third of Duke's generation.

Duke CEO Lynn Good told the news outlet the scenario ending coal-fired generation assumes no technological advances in emissions capture, seemingly leaving open the possibility.

Last year, a report by the Union of Concerned Scientists concluded one in four of the remaining operating coal-fired plants in the U.S. are slated for closure or conversion to natural gas, amid falling power-sector carbon emissions across the country. Duke's report is expected to be released by the end of the month.

Duke's report on its carbon plans comes at the behest of shareholders, a trend utility companies have seen growing among investors who are increasingly concerned about companies' sustainability and their financial exposure to climate policy.

Last year, a majority of shareholders of Pennsylvania utility PPL Corp. called on company management to publish a report on how climate change policies and technological innovations will affect the company's bottom line. Almost 60% of shareholders voted in favor of the non-binding proposal.

The vote, reportedly a first for the power sector, followed a similar decision by shareholders of Occidental Petroleum, which was supported by about 66% of shareholders.

Duke's Good told Axios that right now the utility does not see the coal technology on the horizon that would keep it operating plants. “We don't see that technology today, and we need to make economic decisions to get those units moving and replacing them with natural gas," Good said. However, it does not mean the utility is making near-term efforts to erase coal from its power mix. However, some utilities are taking those steps as they prepare for en energy landscape with more carbon regulations.

In addition to the 25% of coal plants heading for closure or conversion, the UCS report also said that another 17% of the nation’s operating coal plants are uneconomic compared with natural gas-fired generation, and could face retirement soon. But there is plenty of ongoing research into "clean coal" possibilities, and the federal government has expressed an interest in smaller, modular coal units.

Sycamore Energy Manitoba Hydro Lawsuit centers on alleged mismanagement of the solar rebate incentive program, project delays, inspection backlogs, and alleged customer interference, impacting renewable energy installations, contractors, and clean power investment across Manitoba.

Key Points

Claim alleging mismanagement of Manitoba's solar rebate, delays, and inducing customers to switch installers.

✅ Lawsuit alleges mismanaged solar rebate incentive program

✅ Delays in inspections left hundreds of projects incomplete

✅ Claims Hydro urged customers to switch installers for rebates

Sycamore Energy filed a statement of claim Monday in Manitoba Court of Queens Bench against Manitoba Hydro saying it badly mismanaged its Solar Energy Program, a dispute that comes as Canada's solar progress faces criticism nationwide.

The claim also noted the crown corporation caused significant financial and reputational damage to Sycamore Energy, echoing disputes like Ontario wind cancellation costs seen elsewhere.

The statement of claim says Manitoba Hydro was telling customers to find other companies to complete solar panel installations, even as Nova Scotia's solar charge debate has unfolded.

'I'm still waiting': dozens of Manitoba solar system installations in the queue under expired incentive program
This all comes after a pilot project was launched in the province in April 2016, which would allow people to apply for a rebate under the incentive program, while Saskatchewan adjusted solar credits in parallel, and the project would cover about 25 per cent of the installation costs.

The project ended in April 2018, but hundreds of approved projects had yet to be finished.

According to Manitoba Hydro, in November there were 252 approved projects awaiting completion by more than one contractor, and Sycamore Energy said it had about 100 of those projects, a dynamic seen as New England's solar growth strains grid upgrades in other regions.

At the time Sycamore Energy COO, Alex Stuart, blamed Manitoba Hydro for the delays, stating it took too long to get inspections after solar systems were installed.

Scott Powell, Manitoba Hydro’s director of corporate communications, said in November he disagreed with Sycamore Energy’s comments, even as Ontario moves to reintroduce renewables elsewhere.

In a news release, the company said it sold more installations under Manitoba Hydro’s Solar Energy Program compared to other companies and it was instrumental in helping set up standards for the program.

“Manitoba Hydro mismanaged the solar rebate program from the beginning. In the end, they targeted our company unfairly and unlawfully by inducing our customers to break their contracts with us. Manitoba Hydro told our customers they could get an extension to their rebate but only if they switched to different installers,” said Justin Phillips, CEO of Sycamore Energy in a news release.

“We would much rather be installing clean, effective solar power projects for our customers right now. The last thing we want to do is to be suing Manitoba Hydro, but we feel we have no choice. Their actions have cost us millions in lost business. They’ve also cost the province jobs, millions in private investment and a positive way forward to help combat climate change.”

Manitoba Hydro now has 20 days to respond to the action, and a recent Cornwall wind-farm ruling underscores the stakes.

When asked for a response from CTV News, a spokesperson for the Crown corporation said it hadn’t yet been made aware of the suit.

“If a statement of claim is filed and served, we’ll file a statement of defence in due course. As this matter is now apparently before the courts, we have no further comment,” the spokesperson said.

None of these allegations have been proven in court.

Wisconsin Solar and Wind Energy advances as rooftop solar, utility-scale farms, and NREL perovskite solar cells improve efficiency; wind turbines gain via wake modeling, yaw control, and grid-scale battery storage to cut carbon emissions.

Key Points

It is Wisconsin's growth in rooftop and utility-scale solar plus optimized wind turbines to cut carbon emissions.

✅ Perovskite solar cells promise higher efficiency, need longevity

✅ Wake modeling and yaw control optimize wind farm output

✅ Batteries and bids can offset reliance on natural gas

Solar energy in Wisconsin continued to grow in 2019, as more homeowners had rooftop panels installed and big utilities started building multi-panel solar farms.

Wind power is increasing more slowly in the state. However, renewable power developers are again coming forward with proposals for multiple turbines.

Nationally, researchers are working on ways to get even more energy from solar and wind, with the U.S. moving toward 30% electricity from wind and solar in coming years, as states like Wisconsin aim to reduce their carbon emissions over the next few decades.

One reason solar energy is growing in Wisconsin is due to the silicon panels becoming more efficient. But scientists haven't finished trying to improve panel efficiency. The National Renewable Energy Laboratory (NREL) in Golden, Col., is one of the research facilities experimenting with brushing a lab-made solution called perovskite onto a portion of a panel called a solar cell.

In a demonstration video supplied by NREL, senior scientist Maikel van Hest said that, in the lab anyway, the painted cell and its electrical connections called contacts, produce more energy:

"There you go! That's how you paint a perovskite solar cell. And you imagine that ultimately what you could do is you could see a company come in with a truck in front of your house and they would basically paint on the contacts first, dry those, and paint the perovskite over it. That you would have photovoltaic cells on the side of your house, put protective coating on it, and we're done."

Another NREL scientist, David Moore, says the new solar cells could be made faster and help meet what's expected to be a growing global demand for energy. However, Moore says the problem has been lack of stability.

"A solar cell with perovskites will last a couple years. We need to get that to 20-25 years, and that's the big forefront in perovskite research, is getting them to last longer," Moore told members of the Society of Environmental Journalists during a recent tour of NREL.

Another part of improving renewable energy is making wind turbines more productive. At NREL's Insight Center, a large screen showing energy model simulations dominates an otherwise darkened room. Visualization scientist Nicholas Brunhart-Lupo points to a display on the screen that shows how spinning turbines at one edge of a wind farm can cause an airflow called a wake, which curtails the power generation of other turbines.

"So what we find in these simulations is these four turbines back here, since they have this used air, this low-velocity wake being blown to their faces, they're only generating about 20% of the energy they should be generating," he explains.

Brunhart-Lupo says the simulations can help wind farm developers with placement of turbines as well as adjustments to the rotor and blades called the yaw system.

Continued progress with renewables may be vital to any state or national pledges to reduce use of fossil fuels and carbon emissions linked to climate change, including Biden's solar expansion plan as a potential pathway. Some scientists say to limit a rise in global temperature, there must be a big decline in emissions by 2050.

But even utilities that say they support use of more renewables, as why the grid isn't 100% renewable yet makes clear, aren't ready to let go of some energy sources. Jonathan Adelman of Xcel Energy, which serves part of Western Wisconsin, says Xcel is on track to close its last two coal-fired power plants in Minnesota. But he says the company will need more natural gas plants, even though they wouldn't run as often.

"It's not perfect. And it is in conflict with our ultimate goal of being carbon-free," says Adelman. "But if we want to facilitate the transition, we still need resources to help that happen."

Some in the solar industry would like utilities that say they need more natural gas plants to put out competitive bids to see what else might be possible. Solar advocates also note that in some states, energy regulators still favor the utilities.

Meanwhile, solar slowly marches ahead, including here in southeastern Wisconsin, as Germany's solar power boost underscores global momentum.

On the roof of a ranch-style home in River Hills, a work crew from the major solar firm Sunrun recently installed mounting brackets for solar panels.

Sunrun Public Policy Director Amy Heart says she supports research into more efficient renewables. But she says another innovation may have to come in the way regulators think.

"Instead of allowing and thinking about from the perspective of the utility builds the power plant, they replace one plant with another one, they invest in the infrastructure; is really thinking about how can these distributed solutions like rooftop solar, peer-to-peer energy sharing, and especially rooftop solar paired with batteries how can that actually reduce some of what the utility needs?

Large-scale energy storage batteries are already being used in some limited cases. But energy researchers continue to make improvements to them, too, with cheap solar batteries beginning to make widespread adoption more feasible as scientists race to reduce the expected additional harm of climate change.

Cannes Film Festival Power Outage disrupts Alpes-Maritimes as an electrical substation fire and a fallen high-voltage line trigger blackouts; arson probe launched, grid resilience tested, traffic and trains snarled, Palais des Festivals on backup power.

Key Points

A May 24, 2025 blackout in Cannes disrupting events, under arson probe, exposing grid risks across Alpes-Maritimes.

✅ Substation fire and fallen high-voltage line triggered blackouts

✅ Palais des Festivals ran on independent backup power

✅ Authorities probe suspected arson; security measures reviewed

A significant power outage on May 24, 2025, disrupted the final day of the Cannes Film Festival in southeastern France. The blackout, which affected approximately 160,000 households in the Alpes-Maritimes region, including the city of Cannes, occurred just hours before the highly anticipated Palme d'Or ceremony. French authorities are investigating the possibility that the outage was caused by arson.

Details of the Outage

The power disruption began early on Saturday morning with a fire at an electrical substation near Cannes. This incident weakened the local power grid. Shortly thereafter, a high-voltage line fell at another location, further exacerbating the situation. The combined events led to widespread power outages, affecting not only the festival but also local businesses, traffic systems, and public transportation, echoing Heathrow Airport outage warnings raised days before a separate disruption. Traffic lights in parts of Cannes and the nearby city of Antibes stopped working, leading to traffic jams and confusion in city centers. Most shops along the Croisette remained closed, and local food kiosks were only accepting cash. Train service in Cannes was also disrupted. 

Impact on the Festival

Despite the challenges, festival organizers managed to keep the main venue, the Palais des Festivals, operational by switching to an independent power supply. They confirmed that all scheduled events and screenings, including the Closing Ceremony, would proceed as planned, a reminder of how grid operators sometimes avoid rolling blackouts to keep essential services running. The power was restored around 3 p.m. local time, just hours before the ceremony, allowing music to resume and the event to continue without further incident.

Investigations and Suspected Arson

French authorities, including the national gendarmerie, are investigating the possibility that the power outage was the result of arson, aligning with grid attack warnings issued by intelligence services. The prefect for the Alpes-Maritimes region, Laurent Hottiaux, condemned the "serious acts of damage to electrical infrastructures" and stated that all resources are mobilized to identify, track down, arrest, and bring to justice the perpetrators of these acts.

While investigations are ongoing, no official conclusions have been drawn regarding the cause of the outage. Authorities are working to determine whether the incidents were isolated or part of a coordinated effort, a question that also arises when utilities implement PG&E wildfire shutoffs to prevent cascading damage.

Broader Implications

The power outage at the Cannes Film Festival underscores the vulnerability of critical infrastructure to potential acts of sabotage. While the immediate impact on the festival was mitigated, the incident raises concerns about the resilience of energy systems, especially during major public events, and amid severe weather like a B.C. bomb cyclone that leaves tens of thousands without power. It also highlights the importance of having contingency plans in place to ensure the continuity of essential services in the face of unexpected disruptions.

As investigations continue, authorities are urging the public to remain vigilant and report any suspicious activities, while planners also prepare for storm-driven outages that compound emergency response. The outcome of this investigation may have implications for future security measures at large-scale events and the protection of critical infrastructure.

While the Cannes Film Festival was able to proceed with its closing events, the power outage serves as a reminder of the potential threats to public safety, as seen when a Western Washington bomb cyclone left hundreds of thousands without power, and the importance of robust security measures to safeguard against such incidents.

NECEC Clean Energy Connect advances with Maine DEP permits, Hydro-Québec contracts, and rigorous transmission line mitigation, including tapered vegetation, culvert upgrades, and forest conservation, delivering low-carbon power, broadband fiber, and projected ratepayer savings.

Key Points

A Maine transmission project delivering Hydro-Québec power with strict DEP mitigation, lower bills, and added broadband.

✅ DEP permits mandate tapered vegetation, culvert upgrades, land conservation

✅ Hydro-Québec to supply 9.55 TWh/yr via MA contracts; bill savings 2-4%

✅ Added broadband fiber in Somerset and Franklin; local tax benefits

The Maine DEP reviewed the Clean Energy Connect project for more than two years, while regional interest in cross-border transmission continued to grow, before issuing permits that included additional environmental mitigation elements.

"Collectively, the requirements of the permit require an unprecedented level of environmental protection and compensatory land conservation for the construction of a transmission line in the state of Maine," DEP said in a May 11 statement.

Requirements include limits on transmission corridor width, forest preservation, culvert replacement and vegetation management projects, while broader grid programs like vehicle-to-grid integration enhance clean energy utilization across the region.

"In our original proposal we worked hard to develop a project that provided robust mitigation measures to protect the environment," NECEC Transmission CEO Thorn Dickinson said in a statement. "And through this permitting process, we now have made an exceedingly good project even better for Maine."

NECEC will be built on land owned or controlled by Central Maine Power. The 53 miles of new corridor on working forest land will use a new clearing technique for tapered vegetation, while the remainder of the project follows existing power lines.

Environmentalists said they agreed with the decision, and the mitigation measures state regulators took, noting similar momentum behind new wind investments in other parts of Canada.

"Building new ways to deliver low-carbon energy to our region is a critical piece of tackling the climate crisis," CLF Senior Attorney Phelps Turner said in a statement. "DEP was absolutely right to impose significant environmental conditions on this project and ensure that it does not harm critical wildlife areas."

Once complete, Turner said the transmission line will allow the region "to retire dirty fossil fuel plants in the coming years, which is a win for our health and our climate."

The Massachusetts Department of Public Utilities in June 2019 advanced the project by approving contracts for the state's utilities to purchase 9,554,940 MWh annually from Hydro-Quebec. Officials said the project is expected to provide approximately 2% to 4% savings on monthly energy bills.

Total net benefits to Massachusetts ratepayers over the 20-year contract, including both direct and indirect benefits, are expected to be approximately $4 billion, according to the state's estimates.

NECEC "will also deliver significant economic benefits to Maine and the region, including lower electricity prices, increased local real estate taxes and reduced energy costs with examples like battery-backed community microgrids demonstrating local resilience, expanded fiber optic cable for broadband service in Somerset and Franklin counties and funding of economic development for Western Maine," project developers said in a statement.​
