Walmart Canada today announced it has installed a rooftop solar power-generating system as well as a wind turbine at two separate Walmart Canada locations in Ontario. Combined, these projects represent an investment of approximately $2 million.

Located on top of the Kitchener-Waterloo, Ontario store, the rooftop solar power-generating system is expected to generate 450,000 kilowatt hours of energy per year, enough to supply 39 average size Canadian households. The solar system will also reduce greenhouse gas emissions GHG by an estimated 80 tonnes per year.

Adjacent to the Milton, Ontario store, the 20-kilowatt wind turbine is expected to generate as much as 50,000 kilowatt hours of electricity per year, enough to power four average size Canadian households. The wind turbine has been designed for low wind speed areas, where wind power has not been previously practical, and can operate in wind speeds as low as 10 kilometres per hour.

Power generated will be returned to the electrical grid under Ontario's feed-in tariff program for renewable energy. The company will use these pilot projects to assess the effectiveness and potential benefits of these systems to potentially power some of its stores in the future.

"Walmart Canada is committed to one day operating with 100 per cent renewable energy," said Roger Snowball, director of design at Walmart Canada. "These pilot projects allow us to test new technologies in a real-world setting, so that we can apply the best practices and learning to new stores in the future."

The projects also allow Walmart Canada to invest in Canadian businesses. The rooftop solar power-generating system was assembled and installed by BramKal Contractors, of Burlington, Ontario.

Why the Texas Power Grid Is Facing Another Crisis

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.

Customers on the hook for $5.5 billion in deferred BC Hydro operating costs: report

BC Hydro Deferred Regulatory Assets detail $5.5 billion in costs under rate-regulated accounting, to be recovered from ratepayers, highlighting B.C. Utilities Commission oversight, audit scrutiny, financial reporting impacts, and public utility governance.

 

Key Points

BC Hydro defers costs as regulatory assets to recover from ratepayers, influencing rates and financial reporting.

✅ $5.5B in deferred costs recorded as net regulatory assets

✅ Rate impacts tied to B.C. Utilities Commission oversight

✅ Auditor General to assess accounting and governance

 

Auditor General Carol Bellringer says BC Hydro has deferred $5.5 billion in expenses that it plans to recover from ratepayers in the future, as rates to rise by 3.75% over two years.

Bellringer focuses on the deferred expenses in a report on the public utility's use of rate-regulated accounting to control electricity rates for customers.

"As of March 31, 2018, BC Hydro reported a total net regulatory asset of $5.455 billion, which is what ratepayers owe," says the report. "BC Hydro expects to recover this from ratepayers in the future. For BC Hydro, this is an asset. For ratepayers, this is a debt."

She says rate-regulated accounting is used widely across North America, but cautions that Hydro has largely overridden the role of the independent B.C. Utilities Commission to regulate rates.

"We think it's important for the people of B.C. and our members of the legislative assembly to better understand rate-regulated accounting in order to appreciate the impact it has on the bottom line for BC Hydro, for government as a whole, for ratepayers and for taxpayers, especially following a three per cent rate increase in April 2018," Bellringer said in a conference call with reporters.

Last June, the B.C. government launched a two-phase review of BC Hydro to find cost savings and look at the direction of the Crown utility, amid calls for change from advocates.

The review came shortly after a planned government rate freeze was overturned by the utilities commission, which resulted in a three per cent rate increase in April 2018.

A statement by BC Hydro and the government says a key objective of the review due this month is to enhance the regulatory oversight of the commission.

Bellringer's office will become BC Hydro's auditor next year — and will be assessing the impact of regulation on the utility's financial reporting.

"It is a complex area and confidence in the regulatory system is critical to protect the public interest," wrote Bellringer.

Old meters giving away free electricity to thousands of N.B. households

NB Power Smart Meters will replace aging analog meters, boosting billing accuracy, reducing leakage, and modernizing distribution as the EUB considers a $92 million rollout of 360,000 advanced meters for residential and commercial customers.

 

Key Points

NB Power Smart Meters replace analog meters, improving billing accuracy and reducing leakage in the electricity network.

✅ EUB reviewing $92M plan for 360,000 advanced meters

✅ Replaces 98,000 analog units; curbs unbilled kWh

✅ Improves billing accuracy and reduces system leakage

 

Home and business owners with old power meters in New Brunswick have been getting the equivalent of up to 10 days worth of electricity a year or more for free, a multi million dollar perk that will end quickly if the Energy and Utilities Board approves the adoption of smart meters, a move that in other provinces has prompted refusal fees for some holdouts.

Last week the EUB began deliberations over whether to allow NB Power to purchase and install 360,000 new generation smart meters for its residential and commercial customers as part of a $92 million upgrade of its distribution system, even as regulators elsewhere approve major rate changes that affect customer bills.

If approved, that will spell the end to about 98,000 aging electromagnetic or analog meters still used by about one quarter of NB Power customers.  Those are the kind with a horizontal spinning silver disc and clock-face style dials that record consumption 

NB Power lawyer John Furey told the energy and utilities board last week that the utility suspects it loses several million dollars a year to electricity consumed by customers that is not properly recorded by their old meters. It was a central issue in Furey's argument for smart meters amid broader debates over industrial subsidies and debt. (Roger Cosman/CBC)
The analog units, some more than 50 years old and installed back when the late Louis Robichaud and Richard Hatfield were premiers in the 1960's and 1970's - are suspected of doling out millions of kilowatt hours of free power to customers by failing to register all of the current that moves through them.   

"Over time, analog meters slow down and they register lower consumption of electricity than is actually occurring," said NB Power lawyer John Furey last week about the widespread freeloading of power in New Brunswick caused by the old meters.

3 per cent missed
A 2010 report by the independent non-profit Electric Power Research Institute in Palo Alto, California and entered into evidence during NB Power's smart meter hearing said old spinning disc meters generally degrade over time and after 20 years typically fail to register nearly 3 per cent of the power that flows through them.

The average age of analog meters in New Brunswick is much older than that - 31 years - and more than 11,000 of the units are over the age of 40.

"Worn gears, corrosion, moisture, dust, and insects can all cause drag and result in an electromagnetic meter that does not capture the full consumption of the premises," said the report.

The sudden correction to full accounting and billing could naturally surprise these homeowners and even trigger consumer backlash in some cases

- Electric Power Research Institute report
About 94,000 NB residential customers and 3,900 commercial customers have an old meter, according to NB Power records. The group would receive about 40 million kilowatt hours of electricity for free this year  ($5.1 million worth including HST)  if the average unit failed to register 2 percent of the electricity flowing through it, while elsewhere some customers are receiving lump-sum credits on electricity bills.  

That is about $41 in free power for the average residential customer and $322 for the average business.

But, according to the research, there would also be hundreds of customers with meters that have slowed considerably more than the average with 0.3 percent - or close to 300 in NB Power's case -  not counting between 10 and 20 percent of the electricity customers are using. 

NB Power senior Vice President Lori Clark told the EUB stopping the freeloading of power in New Brunswick caused by older meters is in everyone's interest. (Roger Cosman/CBC)
That's potentially $400 in free electricity in a year for a residential customer with average consumption.

"While the average meter might be only slightly slow a few could be significantly so," said the report.

"The sudden correction to full accounting and billing could naturally surprise these homeowners and result in questioning of a new meter, as seen in a shocking $666 bill reported by a Nova Scotia senior." 

The report made the point analog meters can also run fast but called that "less common" meaning that if the EUB approves smart meters, tens of thousands of customers who lose an old meter to a new accurate model will experience higher bills.

'Leakage' reduction
NB Power acknowledges it does not know precisely how much power its older meters give away but said whether it is a little or a lot, ending the freebies is to everyone's benefit. 

"It reduces our inefficiencies, reduces our leakage that we have in the system, so that we are  picking up those unbilled kilowatt hours," said NB Power senior vice president Lori Clark about ending the free power many customers unknowingly enjoy.

Smart meter critics change tone on NB Power's new business case
NB Power's smart meter plan gets major boost with critical endorsements
"Customers benefit from reduced inefficiencies in our system. They benefit from reduced leakage in our system and the fact that those kilowatt hours are being properly billed to the customers that have consumed the kilowatt hours."   

NB Power hopes to win approval of its plan to acquire smart meters by this spring to allow installation beginning in mid 2021, even as some utilities elsewhere have backed away from smart home network projects.

Vehicle-to-grid could be ‘capacity on wheels’ for electricity networks

Vehicle-to-Grid (V2G) enables EV batteries to provide grid balancing, flexibility, and demand response, integrating renewables with bidirectional charging, reducing peaker plant reliance, and unlocking distributed energy storage from millions of connected electric vehicles.

 

Key Points

Vehicle-to-Grid (V2G) lets EVs export power via bidirectional charging to balance grids and support renewables.

✅ Turns parked EVs into distributed energy storage assets

✅ Delivers balancing services and demand response to the grid

✅ Cuts peaker plant use and supports renewable integration

 

“There are already many Gigawatt-hours of batteries on wheels”, which could be used to provide balance and flexibility to electrical grids, if the “ultimate potential” of vehicle-to-grid (V2G) technology could be harnessed.

That’s according to a panel of experts and stakeholders convened by our sister site Current±, which covers the business models and technologies inherent to the low carbon transition to decentralised and clean energy. Focusing mainly on the UK grid but opening up the conversation to other territories and the technologies themselves, representatives including distribution network operator (DNO) Northern Powergrid’s policy and markets director and Nissan Europe’s director of energy services debated the challenges, benefits and that aforementioned ultimate potential.

Decarbonisation of energy systems and of transport go hand-in-hand amid grid challenges from rising EV uptake, with vehicle fuel currently responsible for more emissions than electricity used for energy elsewhere, as Ian Cameron, head of innovation at DNO UK Power Networks says in the Q&A article.

“Furthermore, V2G technology will further help decarbonisation by replacing polluting power plants that back up the electrical grid,” Marc Trahand from EV software company Nuvve Corporation added, pointing to California grid stability initiatives as a leading example.

While the panel states that there will still be a place for standalone utility-scale energy storage systems, various speakers highlighted that there are over 20GWh of so-called ‘batteries on wheels’ in the US, capable of powering buildings as needed, and up to 10 million EVs forecast for Britain’s roads by 2030.

“…it therefore doesn’t make sense to keep building expensive standalone battery farms when you have all this capacity on wheels that just needs to be plugged into bidirectional chargers,” Trahand said.

Is a Resurgence of Nuclear Energy Possible in Germany?

Germany Nuclear Phase-Out reflects a decisive energy policy shift, retiring reactors as firms shun new builds amid high costs, radioactive waste challenges, climate goals, insurance gaps, and debate over small modular reactors and subsidies.

 

Key Points

Germany's policy to end nuclear plants and block new builds, emphasizing safety, waste, climate goals, and viability.

✅ Driven by safety risks, waste storage limits, and insurance gaps

✅ High capital costs and subsidies make new reactors uneconomic

✅ Political debate persists; SMRs raise cost and proliferation concerns

 

A year has passed since Germany deactivated its last three nuclear power plants, marking a significant shift in its energy policy.

Nuclear fission once heralded as the future of energy in Germany during the 1960s, was initially embraced with minimal concern for the potential risks of nuclear accidents. As Heinz Smital from Greenpeace recalls, the early optimism was partly driven by national interest in nuclear weapon technology rather than energy companies' initiatives.

Jochen Flasbarth, State Secretary in the Ministry of Development, reflects on that era, noting Germany's strong, almost naive, belief in technology. Germany, particularly the Ruhr region, grappled with smog-filled skies at that time due to heavy industrialization and coal-fired power plants. Nuclear energy presented a "clean" alternative at the time.

This sentiment was also prevalent in East Germany, where the first commercial nuclear power plant came online in 1961. In total, 37 nuclear reactors were activated across Germany, reflecting a widespread confidence in nuclear technology.

However, the 1970s saw a shift in attitudes. Environmental activists protested the construction of new power plants, symbolizing a generational rift. The 1979 Three Mile Island incident in the US, followed by the catastrophic Chornobyl disaster in 1986, further eroded public trust in nuclear energy.

The Chornobyl accident, in particular, significantly dampened Germany's nuclear ambitions, according to Smital. Post-Chernobyl, plans for additional nuclear power plants in Germany, once numbering 60, drastically declined.

The emergence of the Green Party in 1980, rooted in anti-nuclear sentiment, and its subsequent rise to political prominence further influenced Germany's energy policy. The Greens, joining forces with the Social Democrats in 1998, initiated a move away from nuclear energy, facing opposition from the Christian Democrats (CDU) and Christian Social Union (CSU).

However, the Fukushima disaster in 2011 prompted a policy reversal from CDU and CSU under Chancellor Angela Merkel, leading to Germany's eventual nuclear phase-out in March 2023, after briefly extending nuclear power amid the energy crisis.

Recently, the CDU and CSU have revised their stance once more, signaling a potential U-turn on the nuclear phaseout, advocating for new nuclear reactors and the reactivation of the last shut-down plants, citing climate protection and rising fossil fuel costs. CDU leader Friedrich Merz has lamented the shutdown as a "black day for Germany." However, these suggestions have garnered little enthusiasm from German energy companies.

Steffi Lemke, the Federal Environment Minister, isn't surprised by the companies' reluctance, noting their longstanding opposition to nuclear power, which she argues would do little to solve the gas issue in Germany, due to its high-risk nature and the long-term challenge of radioactive waste management.

Globally, 412 reactors are operational across 32 countries, even as Europe is losing nuclear power during an energy crunch, with the total number remaining relatively stable over the years. While countries like China, France, and the UK plan new constructions, there's a growing interest in small, modern reactors, which Smital of Greenpeace views with skepticism, noting their potential military applications.

In Germany, the unresolved issue of nuclear waste storage looms large. With temporary storage facilities near power plants proving inadequate for long-term needs, the search for permanent sites faces resistance from local communities and poses financial and logistical challenges.

Environment Minister Lemke underscores the economic impracticality of nuclear energy in Germany, citing prohibitive costs and the necessity of substantial subsidies and insurance exemptions.

As things stand, the resurgence of nuclear power in Germany appears unlikely, with economic factors playing a decisive role in its future.

UK homes can become virtual power plants to avoid outages

Demand Flexibility Service rewards households and businesses for shifting peak-time electricity use, enhancing grid balancing, energy security, and net zero goals with ESO and Ofgem support, virtual power plants, and 2GW capacity this winter.

 

Key Points

A grid program paying homes and businesses to shift peak demand, boosting energy security and lowering winter costs.

✅ Pays £3,000/MWh for reduced peak-time usage

✅ Targets at least 2GW via virtual power plants

✅ Rolled out by suppliers with Ofgem and ESO

 

This month we published our analysis of the British electricity system this winter. Our message is clear: in the base case our analysis indicates that supply margins are expected to be adequate, however this winter will undoubtedly be challenging, with high winter energy costs adding pressure. Therefore, all of us in the electricity system operator (ESO) are working round the clock to manage the system, ensure the flow of energy and do our bit to keep costs down for consumers.

One of the tools we have developed is the demand flexibility service, designed to complement efforts to end the link between gas and electricity prices and reduce bills. From November, this new capability will reward homes and businesses for shifting their electricity consumption at peak times. And we are working with the government, businesses and energy providers to encourage as high a level of take-up as possible. We are confident this innovative approach can provide at least 2 gigawatts of power – about a million homes’ worth.

What began as an initiative to help achieve net zero and keep costs down is also proving to be an important tool in ensuring Britain’s energy security, alongside the Energy Security Bill progressing into law.

We are particularly keen to get businesses involved right across Britain. When the Guardian first reported on this service we had calls from businesses ranging from multinationals to an owner of a fish and chip shop asking how they could do their bit and get signed up.

We can now confirm our proposals for how much people and businesses can be paid for shifting their electricity use outside peak times. We anticipate paying a rate of £3,000 per megawatt hour, reflecting the dynamics of UK natural gas and electricity markets today. Businesses and homes can become virtual power plants and, crucially, get paid like one too. For a consumer that could mean a typical household could save approximately £100, and industrial and commercial businesses with larger energy usage could save multiples of this.

We are working with Ofgem to get this scheme launched in November and for it to be rolled out through energy suppliers. If you are interested in participating, or understanding what you could get paid, please contact your energy supplier.

Innovations such as these have never mattered more. Vladimir Putin’s unlawful aggression means we are facing unprecedented energy market volatility, across the continent where Europe’s worst energy nightmare is becoming reality, and pressures on energy supplies this winter.

As a result of Russia’s war in Ukraine, European gas is scarce and prices are high, prompting Europe to weigh emergency measures to limit electricity prices amid the crisis. Alongside this, France’s nuclear fleet has experienced a higher number of outages than expected. Energy shortages in Europe could have knock-on implications for energy supply in Britain.

We have put in place additional contingency arrangements for this winter. For example, the ability to call on generators to fire-up emergency coal units, even as the crisis is a wake-up call to ditch fossil fuels for many, giving Britain 2GW of additional capacity.

We need to be clear, it is possible that without these measures supply could be interrupted for some customers for limited periods of time. This could eventually force us to initiate a temporary rota of planned electricity outages, meaning that some customers could be without power for up to three hours at a time through a process called the electricity supply emergency code (ESEC).

Under the ESEC process we would advise the public the day before any disconnections. We are working with government and industry on planning for this so that the message can be spread across all communities as quickly and accurately as possible. This would include press conferences, social media campaigns, and working with influencers in different communities.
