Green energy activists protest at Pickering nuclear

Summerside Wind Power reached 61% in May, blending renewable energy, municipal utility operations, and P.E.I. wind farms, driving city revenue, advancing green city goals, and laying groundwork for smart grid integration.

Key Points

Summerside Wind Power is the city utility's wind supply, 61% in May, generating revenue that supports local services.

✅ 61% of electricity in May from wind; annual target 45%.

✅ Mix of city-owned farm and West Cape Wind Farm contract.

✅ Revenues projected at $2.9M; funds municipal budget and services.

During the month of May, 61 per cent of the electricity Summerside's homes, businesses and industries used came from wind power sources.

25 per cent was purchased from the West Cape Wind Farm in West Point, P.E.I. — the city has had a contract with it since 2007. The other 36 per cent came from the city's own wind farm, which was built in 2009. 

"One of the strategic goals that was planned for by the city back in 2005 was to try to become a 100 per cent green city," said Greg Gaudet, Summerside's director of municipal services.

"The city started looking at ways it could adopt green practices into its operations on everything it owns and operates and provides services to the community."

Summerside Electric powers about 6,200 residential, 970 commercial and 30 industrial customers and also sells to NB Power, while Nova Scotia Power now generates 30 per cent of its electricity from renewables.

The Summerside Wind Farm is owned by the City of Summerside, which then sells the electricity to Summerside Electric, which it also owns, for profit. 

For the months of April and May, the wind farm generated $630,000 for the city. Last year, it was $507,000 over the same time frame, which does not include a 2 per cent rate increase imposed this year.

"We had a lot of good, strong days of wind for the month of May over other years. So normally we'd be on average somewhere in the range of the 45 per cent range for those months," said Gaudet. 

The city's annual target for wind generation is also 45 per cent, which aligns with the view that more energy sources make better projects. Gaudet said it balances out over the year, with winter being the best and production dropping as low as 25 per cent in the summer months.

At Summerside council's monthly meeting on Monday, May's 61 per cent figure was touted as one of the highest months on record.

"To have one at 61 per cent means we had great production from our wind facilities and contracts, though communities such as Portsmouth have raised turbine noise and flicker concerns in other contexts," Gaudet said.

The utility also owns and provides power through a diesel generation plant.

Municipal money maker
The municipality projects its wind energy production will generate $2.9 million for the city in its current fiscal year, which began April 1, paralleling job gains seen in Alberta's renewables surge this year.

"Any revenues that are received from the wind farm facility goes into the City of Summerside budget," Gaudet said. "Then the council decides on how that money is accrued and where it goes and what it supports in the community."

Wind power generated $2.89 million for the city in the 2019-2020 fiscal year. The budget originally projected $3.2 million in revenue, but blade damage sustained during post-tropical storm Dorian put two turbines out of commission for a few weeks.

Gaudet called this their "only bad year" and officials said they see this year's target to be a bit more conservative and achievable regardless of hiccups and uncontrollable forces, such as the wind they're harnessing.

"It's performed outstandingly well," said Gaudet of the operation.

"There's been no huge, major cost factors with the wind farm to date ... its production has been fairly consistent from year to year." 

Gaudet said the technology has already been piloted at a smaller operation at Credit Union Place, aligning with municipal solar power projects elsewhere.

The goal of the project is to bring Summerside's renewable portfolio up to a yearly average of 62 per cent. Gaudet said it's expected to be commissioned by May 2022 at the latest and after that, the city hopes to focus on smart grid technology.

"It's a long-term goal and I think it's the right [investment] to make," he said. "You have to be environmentally conscious and a steward of your community.

"I think Summerside is that and does that ... a model for North America to look at how a city can work a relationship with an electric utility for the betterment."

Energy Justice Program drives a renewables-based transition, challenging utility monopolies with legal action, promoting rooftop solar, distributed energy, public power, and climate justice to decarbonize the grid and protect communities and wildlife nationwide.

Key Points

A climate justice initiative advancing renewables, legal action, and public power to challenge utility monopolies.

✅ Challenges utility barriers to rooftop solar and distributed energy

✅ Advances state and federal policies for equitable, public power

✅ Uses litigation to curb fossil fuel dependence and protect communities

The Center for Biological Diversity on Monday rolled out a new program to push back against the nation's community- and wildlife-harming energy system that the climate advocacy group says is based on fossil fuels and a "centralized monopoly on power."

The goal of the new effort, the Energy Justice Program, is to help forge a path towards a just and renewables-based energy future informed by equitable regulation principles.

"Our broken energy system threatens our climate and our future," said Jean Su, the Energy Justice Program's new director, in a statement. "Utilities were given monopolies to ensure public access to electricity, but these dinosaur corporations are now hurting the public interest by blocking the clean energy transition, including via coal and nuclear subsidy schemes that profit off the fossil fuel era."

"In this era of climate catastrophe," she continued, "we have to stop these outdated monopolies and usher in a new electricity future that works for people and the planet."

To meet those goals, the new program will pursue a number of avenues, including using legal action to fight utilities' obstruction of clean energy efforts, helping communities advance local solar programs through energy freedom strategies in the South, and crafting energy policies on the state, federal, and international levels in step with commitments from major energy buyers to achieve a 90% carbon-free goal by 2030.

Some of that work is already underway. In June the Center filed a brief with a federal court in a bid to block Arizona power utility Salt River Project from slapping a 60-percent electricity rate hike on rooftop solar customers—amid federal efforts to reshape electricity pricing that critics say are being rushed—a move the group described (pdf) as an obstacle to achieving "the energy transition demanded by climate science."

The Center is among the groups in Energy Justice NC. The diverse coalition seeks to end the energy stranglehold in North Carolina held by Duke Energy, which continues to invest in fossil fuel projects even as it touts clean energy and grid investments in the region.

The time for a new energy system, says the Energy Justice Program, is now, as climate change impacts increasingly strain the grid.

"Amid this climate and extinction emergency," said Su, "the U.S. can't afford to stick with the same centralized, profit-driven electricity system that drove us here in the first place. We have to seize this once-in-a-generation opportunity to design a new system of accountable, equitable, truly public power."

Alberta Rate of Last Resort provides a baseline electricity price, boosting energy reliability, affordability, and consumer protection amid market volatility, aligning with grid modernization, integration, pricing transparency, and oversight from the Alberta Utilities Commission.

Key Points

A fallback electricity rate ensuring affordable, reliable power and consumer protection during market volatility.

✅ Guarantees a stable baseline price when markets spike

✅ Supports vulnerable customers lacking competitive offers

✅ Overseen by AUC to balance protection and competition

The Alberta government has announced significant strides in its electricity market reforms, unveiling a new plan under new electricity rules that aims to enhance energy reliability and affordability for consumers. This initiative, highlighted by the introduction of a "rate of last resort," is a critical response to ongoing challenges in the province's electricity sector, particularly following recent market volatility and increasing consumer concerns about rising electricity prices across the province.

Understanding the Rate of Last Resort

The "rate of last resort" (RLR) is designed to ensure that all Albertans have access to affordable electricity, even when they face challenges securing a competitive rate in the open market. This measure is particularly beneficial for those who may not have the means or the knowledge to navigate complex energy contracts, such as low-income families or seniors.

Under this new plan, the RLR will serve as a safety net, guaranteeing a stable and predictable rate for customers who find themselves without a competitive provider. This move is seen as a crucial step in addressing the needs of vulnerable populations who might otherwise be at risk of being shut out of the energy market.

Market Volatility and Consumer Protection

Alberta's electricity market has faced significant fluctuations over the past few years, and is headed for a reshuffle as policymakers respond to unpredictability in pricing and service availability. The rise in energy costs has caused distress among consumers, with many advocating for stronger protections against sudden price hikes.

The government's recent decision to implement the RLR is a direct acknowledgment of these concerns. By creating a baseline rate, officials aim to provide consumers with peace of mind, knowing that there is a fallback option should market conditions turn unfavorable. This initiative complements other measures aimed at enhancing consumer protections, including improved transparency in pricing, the consumer price cap on power bills being advanced, and the regulation of energy suppliers.

Broader Implications for Alberta’s Energy Landscape

This plan is not only about consumer protection; it also represents a broader shift towards a more sustainable and stable energy market in Alberta, aligning with proposed electricity market changes under consideration. The introduction of the RLR is part of a comprehensive strategy that includes investments in renewable energy and infrastructure improvements. By modernizing the grid and promoting cleaner energy sources, the government aims to reduce dependency on fossil fuels while maintaining reliability and affordability.

Additionally, this move aligns with the province's goals to meet climate targets and transition to a more sustainable energy future as Alberta is changing how it produces and pays for electricity through policy updates. As the demand for clean energy grows, Alberta is positioning itself to be a leader in this transformation, appealing to both residents and businesses committed to sustainability.

Public and Industry Reactions

The announcement has garnered mixed reactions from various stakeholders. While consumer advocacy groups have largely praised the government's efforts to protect consumers and ensure affordable electricity, some industry experts express concerns about potential long-term impacts on competition, arguing the market needs competition to remain dynamic. They argue that while the RLR provides immediate relief, it could disincentivize companies from offering competitive rates, leading to a less dynamic market in the future.

The Alberta Utilities Commission (AUC) is expected to play a pivotal role in overseeing the implementation of the RLR, ensuring that it operates effectively and that any unintended consequences are addressed swiftly. This regulatory oversight will be crucial in balancing consumer protection with the need for a competitive energy market.

Conclusion

As Alberta forges ahead with its electricity market reforms, the introduction of the rate of last resort marks a significant step in enhancing consumer protection and ensuring energy affordability. While challenges remain, the government's proactive approach reflects a commitment to addressing the needs of all Albertans, particularly those most vulnerable to market fluctuations.

In this evolving energy landscape, the RLR will serve not only as a safety net for consumers but also as a foundation for a more sustainable and reliable electricity system. As Alberta continues to adapt to changing energy demands and climate considerations, the effectiveness of these measures will be closely monitored, shaping the future of the province’s electricity market.

Alliant Energy Net-Zero Carbon Plan outlines carbon-neutral electricity by 2050, coal retirements by 2040, major solar and wind additions, gas transition, battery storage, hydrogen, and carbon credits to reduce emissions and lower customer costs.

Key Points

Alliant Energy's strategy to reach carbon-neutral power by 2050 via coal phaseout, renewables, storage, and offsets.

✅ Targets net-zero electricity by 2050

✅ Retires all coal by 2040; expands solar and wind

✅ Uses storage, hydrogen, and offsets to bridge gaps

Alliant Energy has joined a small but growing group of utilities aiming for carbon-neutral electricity by 2050.

In a report released Wednesday, the Madison-based company announced a goal of “net-zero carbon dioxide emissions” from its electricity generation along with plans to eliminate all coal-powered generation by 2040, a decade earlier than the company’s previous target.

Alliant, which is pursuing plans that would make it the largest solar energy generator in Wisconsin, said it is on track to cut its 2005 carbon emissions in half by 2030.

Both goals are in line with targets an international group of scientists warn is necessary to avoid the most catastrophic impacts of climate change. But reducing greenhouse gasses was not the primary motivation, said executive vice president and general counsel Jim Gallegos.

“The primary driver is focused on our customers and communities and setting them up … to be competitive,” Gallegos said. “We do think renewables are going to do it better than fossil fuels.”

Alliant has told regulators it can save customers up to $6.5 billion over the next 35 years by adding more than 1,600 megawatts of renewable generation, closing one of its two remaining Wisconsin coal plants and taking other undisclosed actions.

In a statement, Alliant chairman and CEO John Larsen said the goal is part of broader corporate and social responsibility efforts “guided by our strategy and designed to deliver on our purpose — to serve customers and build stronger communities.”

Coal out; gas remains
The goal applies only to Alliant’s electricity generation — the company has no plans to stop distributing natural gas for heating — and is “net-zero,” meaning the company could use some form of carbon capture or purchase carbon credits to offset continuing emissions.

The plan relies heavily on renewable generation — seen in regions embracing clean power across North America — including the addition of up to 1,000 megawatts of new Wisconsin solar plants by the end of 2023 and 1,000 megawatts of Iowa wind generation added over the past four years — as well as natural gas generators to replace its aging coal fleet.

But Jeff Hanson, Alliant’s director of sustainability, said eliminating or offsetting all carbon emissions will require new tools, such as battery storage or possibly carbon-free fuels such as hydrogen, and awareness of the Three Mile Island debate over the role of nuclear power in the mix.

“Getting to the 2040 goals, that’s all based on the technologies of today,” Hanson said. “Can we get to net zero today? The challenge would be a pretty high bar to clear.”

Gallegos said the plan does not call for the construction of more large-scale natural gas generators like the recently completed $700 million West Riverside Energy Center in Beloit, though natural gas will remain a key piece of Alliant’s generation portfolio.

Alliant announced plans in May to close its 400-megawatt Edgewater plant in Sheboygan by the end of 2022, echoing how Alberta is retiring coal by 2023 as markets shift, but has not provided a date for the shutdown of the jointly owned 1,100-megawatt Columbia Energy Center near Portage, which received about $1 billion worth of pollution-control upgrades in the past decade.

Alliant’s Iowa subsidiary plans to convert its 52-year-old, 200-megawatt Burlington plant to natural gas by the end of next year and a pair of small coal-fired generators in Linn County by 2025. That leaves the 250-megawatt plant in Lansing, which is now 43 years old, and the 734-megawatt Ottumwa plant as the remaining coal-fired generators, even as others keep a U.S. coal plant running indefinitely elsewhere.

Earlier this year, the utility asked regulators to approve a roughly $900 million investment in six solar farms across the state with a total capacity of 675 megawatts, similar to plans in Ontario to seek new wind and solar to address supply needs. The company plans to apply next year for permission to add up to 325 additional megawatts.

Alliant said the carbon-neutral plan, which entails closing Edgewater along with other undisclosed actions, would save customers between $2 billion and $6.5 billion through 2055 compared to the status quo.

Tom Content, executive director of the Citizens Utility Board, said the consumer advocacy group wants to ensure that ratepayers aren’t forced to continue paying for coal plants that are no longer needed while also paying for new energy sources and would like to see a bigger role for energy efficiency and more transparency about the utilities’ pathways to decarbonization.

‘They could do better’
Environmental groups said the announcement is a step in the right direction, though they say utilities need to do even more to protect the environment and consumers.

Amid competition from cheaper natural gas and renewable energy and pressure from environmentally conscious investors, U.S. utilities have been closing coal plants at a record pace in recent years, as industry CEOs say a coal comeback is unlikely in the U.S., a trend that is expected to continue through the next decade.

“This is not industry leadership when we’re talking about emission reductions,” said Elizabeth Katt Reinders, regional campaign director for the Sierra Club, which has called on Alliant to retire the Columbia plant by 2026.

Closing Edgewater and Columbia would get Alliant nearly halfway to its emissions goals while saving customers more than $250 million over the next decade, according to a Sierra Club study released earlier this year.

“Retiring Edgewater was a really good decision. Investing in 1,000 megawatts of new solar is game-changing for Wisconsin,” Katt Reinders said. “In the same breath we can say this emissions reduction goal is unambitious. Our analysis has shown they can do far more far sooner.”

Scott Blankman, a former Alliant executive who now works as director of energy and air programs for Clean Wisconsin, said Alliant should not run the Columbia plant for another 20 years.

“If they’re saying they’re looking to get out of coal by 2040 in Wisconsin I’d be very disappointed,” Blankman said. “I do think they could do better.”

Alliant is the 15th U.S. investor-owned utility to set a net-zero target, according to the Natural Resources Defense Council, joining Madison Gas and Electric, which announced a similar goal last year. Minnesota-based Xcel Energy, which serves customers in western Wisconsin, was the first large investor-owned utility to set such a target, as state utilities report declining returns in coal operations.

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.

Texas Power Grid Reliability faces record peak demand as ERCOT balances renewable energy, wind and solar variability, gas-fired generation, demand response, and transmission limits to prevent blackouts during heat waves and extreme weather.

Key Points

Texas Power Grid Reliability is ERCOT's capacity to meet peak demand with diverse resources while limiting outages.

✅ Record heat drives peak demand across ERCOT.

✅ Variable wind/solar need firm, flexible capacity.

✅ Demand response and reserves reduce blackout risk.

The electric power grid in Texas, which collapsed dramatically during the 2021 winter storm across the state, is being tested again as the state suffers unusually hot summer weather. Demand for electricity has reached new records at a time of rapid change in the mix of power sources as wind and solar ramp up. That’s feeding a debate about the dependability of the state’s power. 

1. Why is the Texas grid under threat again? 

Already the biggest power user in the nation, electricity use in the second most-populous state surged to record levels during heat waves this summer. The jump in demand comes as the state becomes more dependent on intermittent renewable power sources, raising concerns among some critics that more reliance on wind and solar will leave the grid more vulnerable to disruption. Green sources will produce almost 40% of the power in Texas this year, US Energy Information Administration data show. While that trails California’s 52%, Texas is a bigger market. It’s already No. 1 in wind, making it the largest clean energy market in the US. 

2. How is Texas unique? 

The spirit of defiance of the Lone Star State extends to its power grid as well. The Electric Reliability Council of Texas, or Ercot as the grid operator is known, serves about 90% of the state’s electricity needs and has very few high-voltage transmission lines connecting to nearby grids. It’s a deliberate move to avoid federal oversight of the power market. That means Texas has to be mainly self-reliant and cannot depend on neighbors during extreme conditions. That vulnerability is a dramatic twist for a state that’s also the energy capital of the US, thanks to vast oil and natural gas producing fields. Favorable regulations are also driving a wind and solar boom in Texas. 

3. Why the worry? 

The summer of 2023 will mark the first time all of the state’s needs cannot be met by traditional power plants, like nuclear, coal and gas. A sign of potential trouble came on June 20 when state officials urged residents to conserve power because of low supplies from wind farms and unexpected closures of fossil-fuel generators amid supply-chain constraints that limited availability. As of late July, the grid was holding up, thanks to the help of renewable sources. Solar generation has been coming in close to expected summer capacity, or exceeding it on most days. This has helped offset the hours in the middle of the day when wind speeds died down in West Texas. 

4. Why didn’t the grid’s problems get fixed? 

There is no easy fix. The Texas system allows the price of electricity to swing to match supply and demand. That means high prices — and high profits — drive the development of new power plants. At times spot power prices have been as low as $20-$50 a megawatt-hour versus more than $4,000 during periods of stress. The limitation of this pricing structure was laid bare by the 2021 winter blackouts. Since then, state lawmakers have passed market reforms that require weatherization of critical infrastructure and changed rules to put more money in the pockets of the owners of power generation.  

5. What’s the big challenge? 

There’s a real clash going on over what the grid of the future should look like in Texas and across the country, especially as severe heat raises blackout risks nationally. The challenge is to make sure nuclear and fossil fuel plants that are needed right now don’t retire too early and still allow newer, cleaner technologies to flourish. Some conservative Republicans have blamed renewable energy for destabilizing the grid and have pushed for more fossil-fuel powered generators. Lawmakers passed a controversial $10 billion program providing low-interest loans and grants to build new gas-fired plants using taxpayer money, but Texans ultimately have to vote on the subsidy. 

6. Why do improvements take so long? 

Figuring out how to keep the lights on without overburdening consumers is becoming a greater challenge amid more extreme weather fueled by climate change. As such, changing the rules is often a hotly contested process pitting utilities, generators, manufacturers, electricity retailers and other groups against one another. The process became more politicized after the storm in 2021 with Republican Gov. Greg Abbott and lawmakers ordering Ercot to make changes. Building more transmission lines and connecting to other states can help, but such projects are typically tied up for years in red tape.

7. What can be done? 

The price cap for electricity was cut from $9,000/MWh to $5,000 to help avoid the punitive costs seen in the 2021 storm, though prices are allowed to spike more easily. Ercot is also contracting for more reserves to be online to help avoid supply shortfalls and improve reliability for customers, which added $1.7 billion in consumer costs alone last year. Another rule helps some gas generators pay for their fuel costs, while a more recent reform put in price floors when reserves fall to certain levels. Many power experts say that the easiest solution is to pay people to reduce their energy consumption during times of grid stress through so-called demand response programs. Factories, Bitcoin miners and other large users are already compensated to conserve during tight grid conditions.
