France Nuclear Heatwave Restrictions signal reduced nuclear power along the Rhone River as EDF imposes output limits due to high water temperatures, grid needs, with minimal price impact amid strong solar and exports.

Key Points

Temporary EDF output limits at Rhone River reactors due to hot water, protecting ecosystems and grid reliability.

✅ EDF expects halved output at Bugey and Saint Alban.

✅ Cuts align with water temperature and discharge rules.

✅ Weekend midday curtailments offset by solar supply.

The high temperature warning has come early this year but will affect fewer nuclear power plants. High temperatures could halve nuclear power production, with river temperature limits at plants along France's Rhone River this week. 

Output restrictions are expected at two nuclear plants in eastern France due to high temperature forecasts, nuclear operator EDF said. It comes several days ahead of a similar warning that was made last year but will affect fewer plants, and follows a period when power demand has held firm during lockdowns across Europe.

The hot weather is likely to halve the available power supply from the 3.6 GW Bugey plant from 13 July and the 2.6 GW Saint Alban plant from 16 July, the operator said.

However, production will be at least 1.8 GW at Bugey and 1.3 GW at Saint Alban to meet grid requirements, and may change according to grid needs, the operator said.

Kpler analyst Emeric de Vigan said the restrictions were likely to have little effect on output in practice. Cuts are likely only at the weekend or midday when solar output was at its peak so the impact on power prices would be slim.

He said the situation would need monitoring in the coming weeks, however, noting it was unusually early in the summer for nuclear-powered France to see such restrictions imposed.

Water temperatures at the Bugey plant already eclipsed the initial threshold for restrictions on 9 July, as European power hits records during the heatwave. They are currently forecast to peak next week and then drop again, Refinitiv data showed.

"France is currently net exporting large amounts of power – and, despite a nuclear power dispute with Germany, single nuclear units' supply restrictions will not have the same effect as last year," Refinitiv analyst Nathalie Gerl said.

The Garonne River in southern France has the highest potential for critical levels of warming, but its Golfech plant is currently offline for maintenance until mid-August, as Europe faces nuclear losses, the data showed.

"(The restrictions were) to be expected and it will probably occur more often," Greenpeace campaigner Roger Spautz said.

"The authorities must stick to existing regulations for water discharges. Otherwise, the ecosystems will be even more affected," he added.

Alberta Electricity Demand Record surges during a deep freeze, as AESO reports peak load in megawatts and ENMAX notes increased usage in Calgary and Edmonton, with thermostats up amid a cold snap straining power grid.

Key Points

It is the highest electricity peak load recorded by AESO, reflecting maximum grid usage during cold snaps.

✅ AESO reported 11,729 MW peak during the deep freeze

✅ ENMAX saw a 13 percent demand jump week over week

✅ Cold snap drove thermostats up in Calgary and Edmonton

Albertans are cranking up their thermostats and blasting heat into their homes at overwhelmingly high rates as the deep freeze continues across the region. 

It’s so cold that the province set a new all-time record Tuesday evening for electricity usage. 

According to the Alberta Electric System Operator (AESO), as electricity prices spike in Alberta during extreme demand, 11,729 MW of power was used around 7 p.m. Tuesday, passing the previous record set in January of last year by 31 MW.

Temperatures reached a low of -29 C in Calgary, where rising electricity bills have strained budgets, on Tuesday while Edmonton saw a low of -30 C, according to Environment Canada. Wind chill  made it feel closer to -40.

“That increase — 31 Megawatts — is sizeable and about the equivalent of a moderately sized generation facility,” said AESO communications director, Mike Deising. 

“We do see higher demand in winter because it’s cold and it’s dark and that’s really exactly what we’re seeing right now as demand goes up, people turn on their lights and turn up their furnaces,” and with the UCP scrapping the price cap earlier that’s really exactly what we’re seeing right now as demand goes up, people turn on their lights and turn up their furnaces.”

Deising adds Alberta’s electricity usage over the last year has actually been much lower than average, though experts urge Albertans to lock in rates amid expected volatility, despite more people staying home during the pandemic. 

That trend was continuing into 2021, but as Alberta's rising electricity prices draw attention, it’s expected that more records could be broken. 

“If the cold snap continues we may likely set another record (Wednesday) or (Thursday), depending on what happens with the temperatures,” he said. 

Meanwhile, ENMAX has reported an average real-time system demand of 1,400 MW for the city of Calgary. 

That amount is still a far cry from the current season record of 1,619 MW (Aug. 18, 2020), the all-time winter record of 1,653MW (Dec. 2, 2013), and the all-time summer record of 1,692 MW (Aug. 10, 2018). 

ENMAX says electricity demand has increased quite significantly over the past week — by about 13 per cent — since the cold snap set in. 

As a result, the energy company is once again rolling out its ‘Winter Wise’ campaign in an effort to encourage Calgarians to manage both electricity and natural gas use in the winter, even as a consumer price cap on power bills is enabled by new legislation.

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

Key Points

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

✅ Utility can increase or reduce daily consumption at the mill

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

✅ Regulators reviewing cost allocation, monitoring, and viability

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

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

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

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

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

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

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

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

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

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

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

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

Still, he sees value in the proposal.

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

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

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

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

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

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

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

Commercial Electric Tariffs explain utility rate structures, peak demand charges, kWh vs kW pricing, time-of-use periods, voltage, delivery, capacity ratchets, and riders, guiding facility managers in tariff analysis for accurate energy savings.

Key Points

Commercial electric tariffs define utility pricing for energy, demand, delivery, time-of-use periods, riders, and ratchet charges.

✅ Separate kWh charges from kW peak demand fees.

✅ Verify time-of-use windows and demand interval length.

✅ Review riders, capacity ratchets, and minimum demand clauses.

Especially during these tough economic times, as major changes to electric bills are debated in some states, facility executives who don’t understand how their power is priced have been disappointed when their energy projects failed to produce expected dollar savings. Here’s how not to be one of them.

Your electric rate is spelled out in a document called a “tariff” that can be downloaded from your utility’s web page. A tariff should clearly spell out the costs for each component that is part of your rate, reflecting cost allocation practices in your region. Don’t be surprised to learn that it contains a bunch of them. Unlike residential electric rates, commercial electric bills are not based solely on the quantity of kilowatt-hours (kWh) consumed in a billing period (in the United States, that’s a month). Instead, different rates may apply to how your power is supplied, how it is delivered via electricity delivery charges, when it was consumed, its voltage, how fast it was used (in kW), and other factors.

If a tariff’s lingo and word structure are too opaque, spend some time with a utility account rep to translate it. Many state utility commissions also have customer advocates that may assist as they explore new utility rate designs that affect customers. Alternatively, for a fee, facility managers can privately chat with an energy consultant.

Common mistakes

Many facility managers try to estimate savings based on an averaged electric rate, i.e., annual electric spend divided by annual kWh. However, in markets where electricity demand is flat, such a number may obscure the fastest rising cost component: monthly peak demand charges, measured in dollars per kW (or kilo-volt-amperes, kVA).

This charge is like a monthly speeding ticket, based solely on the highest speed you drove during that time. In some areas, peak demand charges now account for 30 to 60 percent of a facility’s annual electric spend. When projecting energy cost savings, failing to separately account for kW peak demand and kWh consumption may result in erroneous results, and a lot of questions from the C-suite.

How peak demand charges are calculated varies among utilities. Some base it on the highest average speed of use across one hour in a month, while others may use the highest average speed during a 15- or 30-minute period. Others may average several of the highest speeds within a defined time period (for example, 8 a.m. to 6 p.m. on weekdays). It is whatever your tariff says it is.

Because some power-consuming (or producing) devices, including those tied to smart home electricity networks, vary in their operation or abilities, they may save money on a few — but not all — of those rate components. If an equipment vendor calculates savings from its product by using an average electric rate, take pause. Tell the vendor to return after the proposal has been redone using tariff-based numbers.

When a vendor is the only person calculating potential savings from using a product, there’s also a built-in conflict of interest: The person profiting from an equipment sale should not also be the one calculating its expected financial return. Before signing any energy project contracts, it’s essential that someone independent of the deal reviews projected savings. That person (typically an energy or engineering consultant) should be quite familiar with your facility’s electric tariff, including any special provisions, riders, discounts, etc., that may pertain. When this doesn’t happen, savings often don’t occur as planned. 

For example, some utilities add another form of demand charge, based on the highest kW in a year. It has various names: capacity, contract demand, or the generic term “ratchet charge.” Some utilities also have a minimum ratchet charge which may be based on a percent of a facility’s annual kW peak. It ensures collection of sufficient utility revenue to cover the cost of installed transmission and distribution even when a customer significantly cuts its peak demand.

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.
