The City of Charlottetown has signed an agreement with a company called Bullfrog Power to buy electricity from sustainable sources, at a premium of two cents a kilowatt-hour.
Councillors voted unanimously to accept the deal.
"One of the main goals of our plan is to reduce our green house gas emissions so we're leading by example," said Coun. Rob Lantz.
Bullfrog Power has purchased energy from the West Cape Wind Farm to supply its customers.
While taxpayers will pay two cents more per kilowatt-hour for electricity at city hall, Lantz said it will be a financial wash because the province is reducing electricity rates by about 14 per cent. Holly Bond, Bullfrog's director of sales and marketing for eastern Canada, said the company will also work with the city to reduce energy use.
"They're going to be paying a little bit more for their electricity," said Bond.
"But once we start engaging the employees in city hall, let's see how much we can reduce their electricity bill by."
The one-year deal includes an energy audit, as well as conservation seminars for both employees and the public.
Nighttime Thermoelectric Generator converts radiative cooling into renewable energy, leveraging outer space cold; a Stanford-UCLA prototype complements solar, serving off-grid loads with low-power output during peak evening demand, using simple materials on a rooftop.
Key Points
A device converting nighttime radiative cooling into electricity, complementing solar for low-power evening needs.
✅ Uses thermocouples to convert temperature gradients to voltage.
✅ Exploits radiative cooling to outer space for night power.
✅ Complements solar; low-cost parts suit off-grid applications.
Two years ago, one freezing December night on a California rooftop, a tiny light shone weakly with a little help from the freezing night air. It wasn't a very bright glow. But it was enough to demonstrate the possibility of generating renewable power after the Sun goes down.
Working with Stanford University engineers Wei Li and Shanhui Fan, University of California Los Angeles materials scientist Aaswath Raman put together a device that produces a voltage by channelling the day's residual warmth into cooling air, effectively generating electricity from thin air with passive heat exchange.
"Our work highlights the many remaining opportunities for energy by taking advantage of the cold of outer space as a renewable energy resource," says Raman.
"We think this forms the basis of a complementary technology to solar. While the power output will always be substantially lower, it can operate at hours when solar cells cannot."
For all the merits of solar energy, it's just not a 24-7 source of power, although research into nighttime solar cells suggests new possibilities for after-dark generation. Sure, we can store it in a giant battery or use it to pump water up into a reservoir for later, but until we have more economical solutions, nighttime is going to be a quiet time for renewable solar power.
Most of us return home from work as the Sun is setting, and that's when energy demands spike to meet our needs for heating, cooking, entertaining, and lighting.
Unfortunately, we often turn to fossil fuels to make up the shortfall. For those living off the grid, it could require limiting options and going without a few luxuries.
Shanhui Fan understands the need for a night time renewable power source well. He's worked on a number of similar devices, including carbon nanotube generators that scavenge ambient energy, and a recent piece of technology that flipped photovoltaics on its head by squeezing electricity from the glow of heat radiating out of the planet's Sun-warmed surface.
While that clever item relied on the optical qualities of a warm object, this alternative device makes use of the good old thermoelectric effect, similar to thin-film waste-heat harvesting approaches now explored.
Using a material called a thermocouple, engineers can convert a change in temperature into a difference in voltage, effectively turning thermal energy into electricity with a measurable voltage. This demands something relatively toasty on one side and a place for that heat energy to escape to on the other.
The theory is the easy part – the real challenge is in arranging the right thermoelectric materials in such a way that they'll generate a voltage from our cooling surrounds that makes it worthwhile.
To keep costs down, the team used simple, off-the-shelf items that pretty much any of us could easily get our hands on.
They put together a cheap thermoelectric generator and linked it with a black aluminium disk to shed heat in the night air as it faced the sky. The generator was placed inside a polystyrene enclosure sealed with a window transparent to infrared light, and linked to a single tiny LED.
For six hours one evening, the box was left to cool on a roof-top in Stanford as the temperature fell just below freezing. As the heat flowed from the ground into the sky, the small generator produced just enough current to make the light flicker to life.
At its best, the device generated around 0.8 milliwatts of power, corresponding to 25 milliwatts of power per square metre.
That might just be enough to keep a hearing aid working. String several together and you might just be able to keep your cat amused with a simple laser pointer. So we're not talking massive amounts of power.
But as far as prototypes go, it's a fantastic starting point. The team suggests that with the right tweaks and the right conditions, 500 milliwatts per square metre isn't out of the question.
"Beyond lighting, we believe this could be a broadly enabling approach to power generation suitable for remote locations, and anywhere where power generation at night is needed," says Raman.
While we search for big, bright ideas to drive the revolution for renewables, it's important to make sure we don't let the smaller, simpler solutions like these slip away quietly into the night.
Norway Electricity Export Limits weigh hydro reservoirs, energy security, EU-UK interconnectors, and record power prices amid Russia gas cuts; Statnett grid constraints and subsidies debate intensify as reservoir levels fall, threatening winter supply.
Key Points
Rules to curb Norway's power exports when reservoirs are very low, protecting supply security and easing extreme prices.
✅ Triggered by low hydro levels and record day-ahead prices
✅ Aims to secure winter supply and expand subsidies
Norway, one of Europe’s biggest electricity exporters, is considering measures to limit power shipments to prevent domestic shortages amid surging prices, according to local media reports.
The government may propose a rule to limit exports if the water level for Norway’s hydro reservoirs drops to “very low” levels, to ensure security of supply, said Energy Minister Terje Aasland, according NTB newswire. The limit would take account of seasonality and would differ across the about 1,800 hydro reservoirs, he said.
Russia’s gas supply cuts in retaliation for European sanctions over the war in Ukraine have triggered the continent’s worst energy crisis in decades, with demand surging for cheap Norwegian hydro electricity. Yet the government faces increasing calls from the public and opposition to limit flows abroad. Prices are near record levels in some parts of the Nordic nation as hydro-reservoir levels have plunged in the south after a drier-than-normal spring.
The government has been under pressure to do something about exports since before April. Flows on the cables are regulated by deals with both the European Union and the UK energy market and Norway can’t simply cut flows. It’s the latest test of European solidarity and a wake-up call for Europe when it comes to energy supplies. Hungary is trying to ban energy exports after it declared an energy emergency.
Back in May, grid operator Statnett SF warned that Norway could face a strained power situation after less snowfall than usual during the winter. At the end of last week, the level of filling in Norwegian hydro reservoirs was 66.5%, compared with a median 74.9% for the corresponding time in 2002-2021, regulator NVE said. Day-ahead electricity prices in southwest Norway soared to a record 423 euros per megawatt-hour late last month, partly due to bottlenecks in the grid limiting supply from the northern regions.
The grid operator has been asked to present by Oct. 1 possible measures that need to be taken to secure supply and infrastructure security ahead of the winter. Statnett operates cables to the UK and Germany aimed at selling surplus electricity and would likely take a financial hit if curbs were introduced. “Operations of these will always follow current laws and regulations,” Irene Meldal, a company spokeswoman, said Friday by email.
Premier Jonas Gahr Store signaled his minority government will file proposals that also include more subsidies to families and companies and align with Europe’s emergency price measures during August, according to an interview with TV2 on Thursday. Meanwhile, opposition politicians plan to hold an extraordinary parliament meeting to discuss boosting the subsidies.
Aasland will summon the parties’ representatives to a meeting on Monday on the electricity crisis, the Aftenposten newspaper reported on Friday, without citing anyone. He intends to inform the parties about the ongoing work and aims to “avoid rushed decisions” by the parliamentary majority.
Norway Faces Pressure to Curb Power Exports as Prices Surge (1)
The nation gets almost all of its electricity from its vast hydro resources. Historically, it has been able to export a hefty surplus and still have among the lowest prices in Europe.
PJM and MISO Electricity-Market Reforms promise consumer savings by enabling renewables, wind, solar, and storage participation in wholesale markets, enhancing grid flexibility, reliability services, and real-time pricing across the Midwest, Great Lakes, and Mid-Atlantic.
Key Points
Market rule updates enabling renewables and storage, improving reliability and lowering consumer costs.
✅ Removes barriers to renewables, storage, demand response
✅ Improves intermarket links and real-time price signals
✅ Rewards flexible resources and reliability services
Electricity-market reforms to enable more renewables generation and storage in the Midwest, Great Lakes, and Mid-Atlantic could save consumers in the US and Canada more than $6.9 billion a year, according to a new report.
The findings may have major implications for consumer groups, large industrial companies, businesses, and homeowners in those regions, said the Wind-Solar Alliance, (WSA), which commissioned the Customer Focused and Clean report.
The WSA is a non-profit organisation supporting the growth of renewables. American Wind Energy Association CEO Tom Kiernan is listed as WSA secretary, amid ongoing debates about the US wind market today.
"Consumers are looking for clean energy, affordable and reliable energy that will keep their monthly electricity bills low," said Kristin Munsch, president of the Board of the Consumer Advocates of the PJM States, which represents over 65 million consumers in 13 states.
"There is great potential to achieve those goals with the cost-effective integration of wind, solar and battery storage plants into our wholesale power markets."
The report found the average residential customer in the PJM and Midcontinent Independent System Operator (MISO) regions, covering 29 US states and the Canadian province of Manitoba, could each save up to $48 a year as lower wholesale electricity prices materialize with significantly more wind, solar and storage on the grid.
The average annual home electricity, for example in New Jersey, in the PJM region, was just over $106 in 2018, according to the US Energy Information Administration.
The latest report quantifies the findings of a previous one for the WSA, published in November 2018, which found that outdated wholesale market rules in the US were preventing full participation by renewable energy, including wind power.
Outdated rules
"The existing wholesale power market rules were largely developed for slower-to-react conventional generators, such as coal and nuclear plants," said Michael Milligan, president of Milligan Grid Solutions and co-author of the new report.
"This report demonstrates the benefits of updating the rules to better accommodate the characteristics and potential contributions of wind and solar and other newer sources of low-cost generation."
With more renewables generation on the grid, customers would benefit the most from increasing power-system flexibility through market structures, the new report concluded. It called for the removal of artificial barriers preventing renewables, storage and demand response from participating in markets.
The report also advocated improving the connections between markets, thereby lowering transaction costs of imports and exports between neighbouring systems.
"There are currently artificial barriers that are preventing the full participation of renewables, storage and other new technologies in the PJM and MISO markets," said Michael Goggin, vice president of Grid Strategies and co-author of the report.
"Providing consumers with a real-time price signal that allows them to adjust their demand, rewarding flexible resources for their capabilities through improved market design, and allowing renewable and storage resources to participate in reliability-services markets would yield the greatest consumer benefits," he said.
PJM and MISO, which incorporate some of the windiest areas of the country, are currently reviewing their market designs as part of a broader grid overhaul underway.
Electricity Security and Firm Capacity underpin reliable supply, balancing variable renewables with grid flexibility via gas plants, nuclear power, hydropower, battery storage, and demand response, safeguarding telework, e-commerce, and critical healthcare operations.
Key Points
Ability to meet demand by combining firm generation and flexible resources, keeping grids stable as renewables grow.
✅ Balances variable renewables with dispatchable generation
✅ Rewards flexibility via capacity markets and ancillary services
✅ Enhances grid stability for critical loads during low demand
The huge disruption caused by the coronavirus crisis, and the low-carbon electricity lessons drawn from it, has highlighted how much modern societies rely on electricity and how firm capacity, such as that provided by nuclear power, is a crucial element in ensuring supply, International Energy Agency (IEA) Executive Director Fatih Birol said.
In a commentary posted on LinkedIn, Birol said: "The coronavirus crisis reminds us of electricity's indispensable role in our lives. It's also providing insights into how that role is set to expand and evolve in the years and decades ahead."
Reliable electricity supply is crucial for teleworking, e-commerce, operating ventilators and other medical equipment, among all its other uses, he said, adding that the hundreds of millions of people who live without any access to electricity are far more vulnerable to disease and other dangers.
"Although new forms of short-term flexibility such as battery storage are on the rise, and initiatives like UK home virtual power plants are emerging, most electricity systems rely on natural gas power plants - which can quickly ramp generation up or down at short notice - to provide flexibility, underlining the critical role of gas in clean energy transitions," Birol said.
"Today, most gas power plants lose money if they are used only from time to time to help the system adjust to shifts in demand. The lower levels of electricity demand during the current crisis are adding to these pressures. Hydropower, an often forgotten workhorse of electricity generation, remains an essential source of flexibility.
"Firm capacity, including nuclear power in countries that have chosen to retain it as an option, is a crucial element in ensuring a secure electricity supply even as soaring electricity and coal use complicate transitions. Policy makers need to design markets that reward different sources for their contributions to electricity security, which can enable them to establish viable business models."
In most economies that have taken strong confinement measures in response to the coronavirus - and for which the IEA has available data - electricity demand has declined by around 15%, largely as a result of factories and businesses halting operations, and in New York City load patterns were notably reshaped during lockdowns. If electricity demand falls quickly while weather conditions remain the same, the share of variable renewables like wind and solar can become higher than normal, and low-emissions sources are set to cover almost all near-term growth.
"With weaker electricity demand, power generation capacity is abundant. However, electricity system operators have to constantly balance demand and supply in real time. People typically think of power outages as happening when surging electricity demand overwhelms supply. But in fact, some of the most high-profile blackouts in recent times took place during periods of low demand," Birol said.
"When electricity from wind and solar is satisfying the majority of demand, and renewables poised to eclipse coal by 2025 are reshaping the mix, systems need to maintain flexibility in order to be able to ramp up other sources of generation quickly when the pattern of supply shifts, such as when the sun sets. A very high share of wind and solar in a given moment also makes the maintenance of grid stability more challenging."
Alberta Electricity Price Surge reflects soaring wholesale rates, natural gas spikes, carbon tax pressures, and grid decarbonization challenges amid cold-weather demand, constrained supply, and Europe-style energy crisis impacts across the province.
Key Points
An exceptional jump in Alberta's power costs driven by gas price spikes, high demand, policy costs, and tight supply.
✅ Wholesale prices averaged $123/MWh in December
✅ Gas costs surged; supply constraints and outages
✅ Carbon tax and decarbonization policies raised costs
Albertans just endured the highest electricity prices in 21 years. Wholesale prices averaged $123 per megawatt-hour in December, more than triple the level from the previous year and highest for December since 2000.
The situation in Alberta mirrors the energy crisis striking Europe where electricity prices are also surging, largely due to a shocking five-fold increase in natural gas prices in 2021 compared to the prior year.
The situation should give pause to Albertans when they consider aggressive plans to “decarbonize” the electric grid, including proposals for a fully renewable grid by 2030 from some policymakers.
The explanation for skyrocketing energy prices is simple: increased demand (because of Calgary's frigid February demand and a slowly-reviving post-pandemic economy) coupled with constrained supply.
In the nitty gritty details, there are always particular transitory causes, such as disputes with Russian gas companies (in the case of Europe) or plant outages (in the case of Alberta).
But beyond these fleeting factors, there are more permanent systemic constraints on natural gas (and even more so, coal-fired) power plants.
I refer of course to the climate change policies of the Trudeau government at the federal level and some of the more aggressive provincial governments, which have notable implications for electricity grids across Canada.
The most obvious example is the carbon tax, the repeal of which Premier Jason Kenney made a staple of his government.
Putting aside the constitutional issues (on which the Supreme Court ruled in March of last year that the federal government could impose a carbon tax on Alberta), the obvious economic impact will be to make carbon-sourced electricity more expensive.
This isn’t a bug or undesired side-effect, it’s the explicit purpose of a carbon tax.
Right now, the federal carbon tax is $40 per tonne, is scheduled to increase to $50 in April, and will ultimately max out at a whopping $170 per tonne in 2030.
Again, the conscious rationale of the tax, aligned with goals for cleaning up Canada's electricity, is to make coal, oil and natural gas more expensive to induce consumers and businesses to use alternative energy sources.
As Albertans experience sticker shock this winter, they should ask themselves — do we want the government intentionally making electricity and heating oil more expensive?
Of course, the proponent of a carbon tax (and other measures designed to shift Canadians away from carbon-based fuels) would respond that it’s a necessary measure in the fight against climate change, and that Canada will need more electricity to hit net-zero according to the IEA.
Yet the reality is that Canada is a bit player on the world stage when it comes to carbon dioxide, responsible for only 1.5% of global emissions (as of 2018).
As reported at this “climate tracker” website, if we look at the actual policies put in place by governments around the world, they’re collectively on track for the Earth to warm 2.7 degrees Celsius by 2100, far above the official target codified in the Paris Agreement.
Canadians can’t do much to alter the global temperature, but federal and provincial governments can make energy more expensive if policymakers so choose, and large-scale electrification could be costly—the Canadian Gas Association warns of $1.4 trillion— if pursued rapidly.
As renewable technologies become more reliable and affordable, business and consumers will naturally adopt them; it didn’t take a “manure tax” to force people to use cars rather than horses.
As official policy continues to make electricity more expensive, Albertans should ask if this approach is really worth it, or whether options like bridging the Alberta-B.C. electricity gap could better balance costs.

BC Hydro Rate Freeze delivers immediate relief on electricity rates in British Columbia, reversing a planned 3% hike, as BCUC oversight, a utility review, and Site C project debates shape provincial energy policy.
Key Points
A one-year provincial policy halting BC Hydro electricity rate hikes while a utility review finds cost savings.
✅ Freeze replaces planned 3% hike approved by BCUC.
✅ Government to conduct comprehensive BC Hydro review.
✅ Critics warn $150M revenue loss impacts capital projects.
British Columbia's NDP government has announced it will freeze BC Hydro rates effective immediately, fulfilling a key election promise.
Energy, Mines and Petroleum Resources Minister Michelle Mungall says hydro rates have gone up by more than 24 per cent in the last four years and by more than 70 per cent since 2001, reflecting proposals such as a 3.75% increase over two years announced previously.
"After years of escalating electricity costs, British Columbians deserve a break on their bills," Mungall said in a news release.
BC Hydro had been approved by the B.C. Utilities Commission to increase the rate by three per cent next year, but Mungall said it will pull back its request in order to comply with the freeze.
In the meantime, the government says it will undertake a comprehensive review of the utility meant to identify cost-savings measures for customers often asked to pay an extra $2 a month on electricity bills.
The Liberal critic, Tracy Redies, says the one year rate freeze is going to cost BC Hydro, calling it a distraction from the bigger issue of the future of the Site C project and the oversight of a BC Hydro fund surplus as well.
"A one year rate freeze costs Hydro $150 million," Redies said. "That means there's $150 million less to invest in capital projects and other investments that the utility needs to make."
"This is putting off decisions that should be made today to the future."
Recommendations from the review — including possible new rates — will be implemented starting in April 2019.
