I'm sitting in the office of Nova Scotia Premier Darrell Dexter and he directs me to a green-tinted glass award sitting on a coffee table.

The award, received by Dexter at the Copenhagen climate summit in December 2009, recognizes Nova Scotia for creating the first law in North America to put a hard cap on carbon emissions.

"We're a small player, we understand, and I don't want to overstate it, but we're trying to help the country meet its climate change goals," Dexter tells me.

Nova Scotia has been quietly cleaning up its act after decades of clinging to coal. It tabled its own green economy act a year before Ontario, but it garnered little recognition across the rest of Canada.

The 2007 legislation tackles smog-causing emissions, greenhouse gases, and mercury from power generation. Emissions from the transportation sector are also targeted, and goals are established for land and water-resource management.

Dexter says it was a good start, and he credits the minority Conservative government at the time for getting the ball rolling. "But there was never any meat on the bone."

So in April his NDP government released a bold renewable electricity plan that lays out a number of clear milestones, including a legal requirement to have 25 per cent of the province's energy mix consist of renewable power by 2015. On top of that, a goal has been set to grow the green mix to 40 per cent by 2020. Even California hasn't such ambition.

To keep electricity demand from growing, an agency called Efficiency Nova Scotia is being created to promote energy conservation and efficiency. Existing demand, meanwhile, will be increasingly met through a combination of wind, biomass and natural gas.

A feed-in-tariff, similar to that introduced in Ontario but limited to smaller community projects, is also being created to encourage local participation.

En route to the 2020 goal, the province hopes that R&D in tidal energy will begin paying off, and that transmission links to New Brunswick and eventually a subsea power cable from Labrador to Cape Breton to the chagrin of Quebec will open up the opportunity to import clean power.

It's a huge step for a province that, unlike Ontario or Quebec, doesn't get most of its power from hydroelectric and nuclear power generation. Nova Scotia currently depends mostly on coal to generate its electricity. In fact, nearly 90 per cent of Nova Scotia's power comes from fossil fuels.

The reasons are historical. The province used to get coal out of its own Cape Breton mines, but in the world of coal it was the dirtiest of the dirty-loaded with mercury and sulphur dioxide.

Mining peaked in the 1940s and went downhill from there, a combination of resource depletion, production and financial difficulties, and stricter environmental controls. The Westray Mine explosion in 1992 that killed 26 miners didn't help matters.

"It became a very expensive, difficult place to mine," says Rob Bennett, chief executive of privately owned Nova Scotia Power. Disclosure: the company invited me to learn of the energy transition going on in the province and covered the cost of my two-day trip.

But the province, having many coal plants already in place, kept feeding its fossil addiction. The only difference is that it had to shop somewhere else. Today it gets 85 per cent of its supply from Columbia and the United States.

The imported coal contains less mercury and sulphur, but it costs more and is subject to the volatility of the market. Sending money out of the province for imported product doesn't support local industry or create local jobs.

It's a bad deal, says Bennett. "I'd rather spend my money here in Nova Scotia."

Dexter is of similar mind, and he sees a full-on embrace of renewable energy as a way to do it. The province's renewable electricity plan expresses this view clearly. "Not making this transition will shackle ratepayers to the wild price swings and the relentless upward march of international energy markets.

"We can keep going down that path and doom consumers to an unsustainable future, or we can bite the bullet and make the necessary investments to have a secure, safe, affordable and sustainable energy economy."

Ontario is also biting the bullet, and like Nova Scotia it's tying green energy to the creation of green jobs and a green economy. We're getting off coal – a lot of coal – and we're replacing it with green power and conservation.

There are some differences in how we're doing it. Ontario Power Generation, for example, is not permitted to develop, own or operate renewable energy projects, with the exception of large hydro projects.

Nova Scotia Power, on the other hand, has been given the go-ahead as a regulated monopoly to take on roughly half of industrial-scale green projects. The other half will be secured through competitive bidding.

"Eighteen months ago we weren't even thinking about wind, now we've got three wind projects," says Mark Savory, vice-president of technical and construction services at Nova Scotia Power.

He says the benefit a large regulated utility brings to the game is a healthy balance sheet and the ability to access cheap capital. This, he argues, ultimately leads to more affordable projects that bring the best value to ratepayers and stability to the market.

Nova Scotia Power is now investing in tidal energy demonstrations in the Bay of Fundy, investigating co-firing of biomass in its coal plants, capturing waste heat from its natural gas plants, and erecting wind turbines across the province. The carbon cap keeps the pressure on, reinforced by the government's renewable energy targets.

As if to signal a new era, an old decommissioned coal plant in Halifax harbour is being retrofitted as the company's new headquarters. The building will be LEED certified gold. It will have a green roof with solar panels. It will also be wrapped in a super-insulated glass skin and heated and cooled with a geoexchange system that uses harbour water.

There's a new attitude in this province, something contagious taking hold that's even drawing people back from faraway places. Take Sean Brennon, who at 34 and with a baby on the way recently returned to Halifax after spending nearly three years working with Suncor Energy on an oil-sands project north of Alberta's Fort McMurray.

He's now project manager of Nova Scotia Power's Digby wind farm project near the Bay of Fundy. The guy oozes with pride and is clearly happy to be home.

"It's my dream job," he tells me as we eat some of Digby's world famous scallops. "I couldn't ask for anything more ideal."

Ontario, B.C., Quebec, Nova Scotia – Canada's green power club is growing.

N.S. abandons Atlantic Loop, will increase wind and solar energy projects

Nova Scotia Clean Power Plan 2030 pivots from the Atlantic Loop, scaling wind and solar, leveraging Muskrat Falls via the Maritime Link, adding battery storage and transmission upgrades to decarbonize grid and retire coal.

 

Key Points

Nova Scotia's 2030 roadmap to replace coal with wind, solar, hydro imports, storage, and grid upgrades.

✅ 1,000 MW onshore wind to supply 50% by 2030

✅ Battery storage sites and New Brunswick transmission upgrades

✅ Continued Muskrat Falls imports via Maritime Link

 

Nova Scotia is abandoning the proposed Atlantic Loop in its plan to decarbonize its electrical grid by 2030 amid broader discussions about independent grid planning nationwide, Natural Resources and Renewables Minister Tory Rushton has announced.

The province unveiled its clean power plan calling for 30 per cent more wind power and five per cent more solar energy in the Nova Scotia power grid over the coming years. Nova Scotia's plan relies on continued imports of hydroelectricity from the Muskrat Falls project in Labrador via the Emera-owned Maritime Link.

Right now Nova Scotia generates 60 per cent of its electricity by burning fossil fuels, mostly coal, and some increased use of biomass has also factored into the mix. Nova Scotia Power must close its coal plants by 2030 when 80 per cent of electricity must come from renewable sources in order reduce greenhouse gas emissions causing climate changes.

Critics have urged reducing biomass use in electricity generation across the province.

The clean power plan calls for an additional 1,000 megawatts of onshore wind by 2030 which would then generate 50 per cent of the the province's electricity, while also advancing tidal energy in the Bay of Fundy as a complementary source.    

"We're taking the things already know and can capitalize on while we build them here in Nova Scotia," said Rushton, "More importantly, we're doing it at a lower rate so the ratepayers of Nova Scotia aren't going to bear the brunt of a piece of equipment that's designed and built and staying in Quebec."

The province says it can meet its green energy targets without importing Quebec hydro through the Atlantic loop. It would have brought hydroelectric power from Quebec into New Brunswick and Nova Scotia via upgraded transmission links. But the government said the cost is prohibitive, jumping to $9 billion from nearly $3 billion three years ago with no guarantee of a secure supply of power from Quebec.

"The loop is not viable for 2030. It is not necessary to achieve our goal," said David Miller, the provincial clean energy director. 

Miller said the cost of $250 to $300 per megawatt hour was five times higher than domestic wind supply.

Some of the provincial plan includes three new battery storage sites and expanding the transmission link with New Brunswick. Both were Nova Scotia Power projects paused by the company after the Houston government imposed a cap on the utility's rate increased in the fall of 2022.

The province said building the 345-kilovolt transmission line between Truro, N.S., and Salisbury, N.B., and an extension to the Point Lepreau Nuclear Generating Station, as well as aligning with NB Power deals for Quebec electricity underway, would enable greater access to energy markets.

Miller says Nova Scotia Power has revived both.

Nova Scotia Power did not comment on the new plan, but Rushton spoke for the company.

"All indications I've had is Nova Scotia Power is on board for what is taking place here today," he said.

UK must start construction of large-scale storage or fail to meet net zero targets.

UK Hydrogen Storage Caverns enable long-duration, low-carbon electricity balancing, storing surplus wind and solar power as green hydrogen in salt formations to enhance grid reliability, energy security, and net zero resilience by 2035 and 2050.

 

Key Points

They are salt caverns storing green hydrogen to balance wind and solar, stabilizing a low-carbon UK grid.

✅ Stores surplus wind and solar as green hydrogen in salt caverns

✅ Enables long-duration, low-carbon grid balancing and security

✅ Complements wind and solar; reduces dependence on flexible CCS

 

The U.K. government must kick-start the construction of large-scale hydrogen storage facilities if it is to meet its pledge that all electricity will come from low-carbon electricity sources by 2035 and reach legally binding net zero targets by 2050, according to a report by the Royal Society.

The report, "Large-scale electricity storage," published Sep. 8, examines a wide variety of ways to store surplus wind and solar generated electricity—including green hydrogen, advanced compressed air energy storage (ACAES), ammonia, and heat—which will be needed when Great Britain's electricity generation is dominated by volatile wind and solar power.

It concludes that large scale electricity storage is essential to mitigate variations in wind and sunshine, particularly long-term variations in the wind, and to keep the nation's lights on. Storing most of the surplus as hydrogen, in salt caverns, would be the cheapest way of doing this.

The report, based on 37 years of weather data, finds that in 2050 up to 100 Terawatt-hours (TWh) of storage will be needed, which would have to be capable of meeting around a quarter of the U.K.'s current annual electricity demand. This would be equivalent to more than 5,000 Dinorwig pumped hydroelectric dams. Storage on this scale, which would require up to 90 clusters of 10 caverns, is not possible with batteries or pumped hydro.

Storage requirements on this scale are not currently foreseen by the government, and the U.K.'s energy transition faces supply delays. Work on constructing these caverns should begin immediately if the government is to have any chance of meeting its net zero targets, the report states.

Sir Chris Llewellyn Smith FRS, lead author of the report, said, "The need for long-term storage has been seriously underestimated. Demand for electricity is expected to double by 2050 with the electrification of heat, transport, and industrial processing, as well as increases in the use of air conditioning, economic growth, and changes in population.

"It will mainly be met by wind and solar generation. They are the cheapest forms of low-carbon electricity generation, but are volatile—wind varies on a decadal timescale, so will have to be complemented by large scale supply from energy storage or other sources."

The only other large-scale low-carbon sources are nuclear power, gas with carbon capture and storage (CCS), and bioenergy without or with CCS (BECCS). While nuclear and gas with CCS are expected to play a role, they are expensive, especially if operated flexibly.

Sir Peter Bruce, vice president of the Royal Society, said, "Ensuring our future electricity supply remains reliable and resilient will be crucial for our future prosperity and well-being. An electricity system with significant wind and solar generation is likely to offer the lowest cost electricity but it is essential to have large-scale energy stores that can be accessed quickly to ensure Great Britain's energy security and sovereignty."

Combining hydrogen with ACAES, or other forms of storage that are more efficient than hydrogen, could lower the average cost of electricity overall, and would lower the required level of wind power and solar supply.

There are currently three hydrogen storage caverns in the U.K., which have been in use since 1972, and the British Geological Survey has identified the geology for ample storage capacity in Cheshire, Wessex and East Yorkshire. Appropriate, novel business models and market structures will be needed to encourage construction of the large number of additional caverns that will be needed, the report says.

Sir Chris observes that, although nuclear, hydro and other sources are likely to play a role, Britain could in principle be powered solely by wind power and solar, supported by hydrogen, and some small-scale storage provided, for example, by batteries, that can respond rapidly and to stabilize the grid. While the cost of electricity would be higher than in the last decade, we anticipate it would be much lower than in 2022, he adds.

More red ink at Manitoba Hydro as need for new power generation looms

Manitoba NDP Energy Financing Strategy outlines public ownership of renewables, halts private wind farms, stabilizes hydroelectric rates, and addresses Manitoba Hydro deficits amid drought, export revenue declines, and rising demand for grid reliability.

 

Key Points

A plan to fund public renewables, pause private wind, and stabilize Manitoba Hydro rates, improving utility finances.

✅ Public ownership favored over private wind contracts

✅ Focus on rate freeze and Manitoba Hydro debt management

✅ Addresses drought impacts, export revenue declines, rising demand

 

Manitoba's NDP administration has declared its intention to formulate a strategy for financing new energy ventures, following a decision to halt the development of additional private-sector wind farms and to extend a pause on new cryptocurrency connections amid grid pressures. This plan will accompany efforts to stabilize hydroelectric rates and manage the financial obligations of the province's state-operated energy company.

Finance Minister Adrien Sala, overseeing Manitoba Hydro, shared these insights during a legislative committee meeting on Thursday, emphasizing the government's desire for future energy expansions to remain under public ownership, even as Ontario moves to reintroduce renewable energy projects after prior cancellations, and expressing trust in Manitoba Hydro's governance to realize these goals.

This announcement was concurrent with Manitoba Hydro unveiling increased financial losses in its latest quarterly report. The utility anticipates a $190-million deficit for the fiscal year ending in March, marking a $29 million increase from its previous forecast and a significant deviation from an initial $450 million profit expectation announced last spring. Contributing factors to this financial downturn include reduced hydroelectric power generation due to drought conditions, diminished export revenues, and a mild fall season impacting heating demand.

The recent financial update aligns with a period of significant changes at Manitoba Hydro, initiated by the NDP government's board overhaul following its victory over the former Progressive Conservative administration in the October 3 election, and comes as wind projects are scrapped in Alberta across the broader Canadian energy landscape.

Subsequently, the NDP-aligned board discharged CEO Jay Grewal, who had advocated for integrating wind energy from third-party sources, citing competitive wind power trends, to promptly address the province's escalating energy requirements. Grewal's approach, though not unprecedented, sought to offer a quicker, more cost-efficient alternative to constructing new Manitoba Hydro dams, highlighting an imminent energy production shortfall projected for as early as 2029.

The opposition Progressive Conservatives have criticized the NDP for dismissing the wind power initiative without presenting an alternate solution, warning about costly cancellation fees seen in Ontario when projects are halted, and emphasizing the urgency of addressing the predicted energy gap.

In response, Sala reassured that the government is in the early stages of policy formulation, reflecting broader electricity policy debates in Ontario about how to fix the power system, and criticized the previous administration for its inaction on enhancing generation capacity during its tenure.

Manitoba Hydro has named Hal Turner as the acting CEO while it searches for Grewal's successor, following controversies such as Solar Energy Program mismanagement raised by a private developer. Turner informed the committee that the utility is still deliberating on its approach to new energy production and is exploring ways to curb rising demand.

Expressing optimism about collaborating with the new board, Turner is confident in finding a viable strategy to fulfill Manitoba's energy needs in a safe and affordable manner.

Additionally, the NDP's campaign pledge to freeze consumer rates for a year remains a priority, with Sala committing to implement this freeze before the next provincial election slated for 2027.

APS asks customers to conserve energy after recent blackouts in California

Arizona Energy Conservation Alert urges APS and TEP customers to curb usage during a heatwave, preventing rolling blackouts, easing peak demand, and supporting grid reliability by raising thermostats, delaying appliances, and pausing pool pumps.

 

Key Points

A utility request during extreme heat to cut demand and protect grid reliability, helping prevent outages.

✅ Raise thermostats to 80 F or higher during peak hours

✅ Delay washers, dryers, dishwashers until after 8 p.m.

✅ Pause pool pumps; switch off nonessential lights and devices

 

After excessive heat forced rolling blackouts for thousands of people across California Friday and Saturday, Arizona Public Service Electric is asking customers to conserve energy this afternoon and evening.

“Given the extended heat wave in the western United States and climate-related grid risks that utilities are monitoring, APS is asking customers to conserve energy due to extreme energy demand that is driving usage higher throughout the region with today’s high temperatures,” APS said in a statement.

Tucson Electric Power has made a similar request of customers in its coverage area.


APS is asking customers to conserve energy in the following ways Tuesday until 8 p.m.:

  • Raise thermostat settings to no lower than 80 degrees.
  • Turn off extra lights and avoid use of discretionary major appliances such as clothes washers, dryers and dishwashers.
  • Avoid operation of pool pumps.

The request from APS also came just hours after Arizona Corporation Commission Chairman Bob Burns sent a letter to electric utilities under the commission's umbrella, like APS, to see if they are in good shape or anticipate any problems given looming shortages in California. He requested the companies respond by noon Friday.


"The whole plan is to take a look at the system early in the Summer," Burns said. "Early May we look at the system, make sure we're ready and able to serve the public throughout the entire heat cycle."

Burns told ABC15 the Summer Preparedness workshop with utilities took place in May and the regulated utilities reported they were well equipped to meet the anticipated peaks of the Summer, even as supply-chain pressures mount across the industry. Tuesday's letter to the electric companies seeks to see if they are still able to "adequately, safely and reliably" serve customers through the heatwave, or if what happened in California could take place here.

"With the activities that are occurring over in California, including tight grid conditions that have repeatedly tested operators, we just want to double check," Burns said.

An APS representative told ABC15 they have adequate supply and reserve and don't anticipate any problems.

However, the rolling blackouts in California also caught the attention of Commissioner Lea Marquez Peterson. She is calling on the chairman to hold an emergency meeting amid wildfire concerns across California and the region.

"The risk to Arizonans and the fact that energy could be interrupted, that we had some kind of rolling blackout like California would have, would be really a public health issue," Peterson said. "It could be life and death in some cases for vulnerable populations."

Perry presses ahead on advanced nuclear reactors

Advanced Nuclear Reactors drive U.S. clean energy with small modular reactors, a new test facility at Idaho National Laboratory, and public-private partnerships accelerating nuclear innovation, safety, and cost reductions through DOE-backed programs and university simulators.

 

Key Points

Advanced nuclear reactors are next-gen designs, including SMRs, offering safer, cheaper, low-carbon power.

✅ DOE test facility at Idaho National Laboratory

✅ Small modular reactors with passive safety systems

✅ University simulators train next-gen nuclear operators

 

Energy Secretary Rick Perry is advancing plans to shift the United States towards next-gen nuclear power reactors.

The Energy Department announced this week it has launched a new test facility at the Idaho National Laboratory where private companies can work on advanced nuclear technologies, as the first new U.S. reactor in nearly seven years starts up, to avoid the high costs and waste and safety concerns facing traditional nuclear power plants.

“[The National Reactor Innovation Center] will enable the demonstration and deployment of advanced reactors that will define the future of nuclear energy,” Perry said.

With climate change concerns growing and net-zero emissions targets emerging, some Republicans and Democrats are arguing for the need for more nuclear reactors to feed the nation’s electricity demand. But despite nuclear plants’ absence of carbon emissions, the high cost of construction, questions around what to do with the spent nuclear rods and the possibility of meltdown have stymied efforts.

A new generation of firms, including Microsoft founder Bill Gates’ Terra Power venture, are working on developing smaller, less expensive reactors that do not carry a risk of meltdown.

“The U.S. is on the verge of commercializing groundbreaking nuclear innovation, and we must keep advancing the public-private partnerships needed to traverse the dreaded valley of death that all too often stifles progress,” said Rich Powell, executive director of ClearPath, a non-profit advocating for clean energy and green industrial strategies worldwide.

The new Idaho facility is budgeted at $5 million under next year’s federal budget, even as the cost of U.S. nuclear generation has fallen to a ten-year low, which remains under negotiation in Congress.

On Thursday another advanced nuclear developer working on small modular systems, Oregon-based NuScale Power, announced it was building three virtual nuclear control rooms at Texas A&M University, Oregon State University and the University of Idaho, with funding from the Energy Department.

The simulators will be open to researchers and students, to train on the operation of smaller, modular reactors, as well as the general public.

NuScale CEO John Hopkins said the simulators would “help ensure that we educate future generations about the important role nuclear power and small modular reactor technology will play in attaining a safe, clean and secure energy future for our country.”

✅ Sichuan-Tibet junction on the Jinsha River

✅ 2,000 MW capacity; four turbine-generator units

✅ 8.36 bn kWh/yr; US$4.59b total; Huadian 48% stake

 

China has approved construction of the 2,000-MW Lawa hydropower station, a Yangtze tributary hydropower project on the Jinsha River, multiple news agencies are reporting.

Lawa, at the junction of Sichuan province and the Tibet autonomous region, will feature a 784-foot-high dam and the reservoir will submerge about 12 square miles of land. The Jinsha River is a tributary of the Yangtze River, and the project aligns with green hydrogen development in China.

The National Development and Reform Commission of the People’s Republic of China, which also guides China's nuclear energy development as part of national planning, is reported to have said that four turbine-generator units will be installed, and the project is expected to produce about 8.36 billion kWh of electricity annually.

Total investment in the project is to be US$4.59 billion, and Huadian Group Co. Ltd. will have a 48% stake in the project, reflecting overseas power infrastructure activity, with minority stakes held by provincial firms, according to China Daily.

In other recent news in China, Andritz received an order in December 2018 to supply four 350-MW reversible pump-turbines and motor-generators, alongside progress in compressed air generation technologies, for the 1,400-MW ZhenAn pumped storage plant in Shaanxi province.
