Toronto hospitals are breathing a sigh of relief because a possible radioactive isotope shortage has been averted.

"We were lucky this time around," said Dawn-Marie King, director of clinical operations for the joint department of medical imaging for Toronto General, Toronto Western, Princess Margaret, Women's College and Mount Sinai hospitals. "We should end up with isotopes on (December 18) of this week."

The Chalk River nuclear facility, which produces the medical isotopes, was shut down Dec. 4 for routine maintenance and to make a configuration change for research unrelated to medical isotopes, said Atomic Energy of Canada Ltd. spokesperson Dale Coffin.

That maintenance lasted six-and-a-half days, which was longer than expected, Coffin said, and prompted some to fear a possible global shortfall of radioactive isotopes. AECL produces more than half of the world's medical isotopes.

But the shortfall was short-lived and any crisis has now been avoided since Chalk River went back into full production December 12, said Dr. Christopher O'Brien, president of the Ontario Association of Nuclear Medicine and medical director of nuclear medicine at Brantford General Hospital.

"This is good news now, but this also reflects things to come," O'Brien said. "There is no replacement for Chalk River and if it goes down for any specific period of time we will be in dire straights."

Meanwhile, about 20 to 30 patients who needed tests at Toronto hospitals had to be rescheduled because of the temporary shortage of isotopes.

Coffin said the reactor operates on a 21-day cycle: 16 days of operation followed by a routine five-day closure for regular maintenance.

He said the reactor always boosts production before its routine closure, and has been producing on average 30 to 40 per cent more medical isotopes than usual to compensate for a closure in Europe.

A statement released by Natural Resources Minister Lisa Raitt said at Canada's request, several governments and industry will meet in January in France to discuss the security of isotope supply.

Last year Chalk River, known as the National Research Universal reactor, was shut down for a prolonged period over safety concerns, causing a shortage of medical isotopes worldwide. Hospitals use the isotopes for nuclear imaging testing that can help diagnose a wide array of problems, including heart disease, blood clots and cancer.

Power Demand Seen Holding Firm In Europe’s Latest Lockdown

European Power Demand During Second Lockdowns remains resilient as winter heating offsets commercial losses; electricity consumption tracks seasonal norms, with weather sensitivity, industrial activity, natural gas shielding, and coal decline shaping dynamics under COVID-19 restrictions.

 

Key Points

It is expected to remain near seasonal norms, driven by heating, industry activity, and weather sensitive consumption.

✅ Winter heating offsets retail and hospitality closures

✅ Demand sensitivity rises with colder weather in France

✅ Gas generation shielded; coal likely to curtail first

 

European power demand is likely to hold up in the second round of national lockdown restrictions, with fluctuations most likely driven by changes in the weather.

Traders and analysts expect normal consumption this time around as home heating during the chilly season replaces commercial demand.

Last week electricity consumption in France, Germany and the U.K. was close to business-as-usual levels for the time of year, according to BloombergNEF data. By contrast, power demand had dropped 16% in the first seven days of the springtime lockdown, as reflected by the U.K.’s 10% daily decline reported then.

How power demand performs has significance outside the sector. It’s often seen as a proxy for economic growth and during lockdowns earlier this year, electricity use slumped along with GDP, and stunted hydro and nuclear output could further hobble recovery. For Western Europe, annual demand is expected to be 5% lower than the previous year, a bigger decline than after the global financial crisis in 2008, according to S&P Global Platts.

The Covid-19 limits are lighter than those from earlier in the year “with an explicit drive to preserve economic activity, particularly at the more energy-intensive industrial end of the spectrum,” said Glenn Rickson, head of European power analysis at S&P Global Platts.

Higher levels of working from home will offset some of the losses from shop and hospitality closures, “but also increase the temperature sensitivity of overall gas and power demand, as heat-driven demand records have shown in recent summers,” he said.

The latest wave of national lockdowns began in France, Germany, Spain, Italy and Britain, with Spain having seen April demand plummet earlier in the year, as coronavirus cases surged and officials struggled to keep the spread of the virus under control.

Much of the manufacturing industry remains working for now despite additional restrictions to contain the coronavirus. With the peak of the second wave yet to be reached, “it seems almost inevitable that the fourth quarter will prove economically challenging,” analysts at Alfa Energy said.

There will initially be significantly less of an impact on demand compared with this spring when global daily demand dipped about 15% and electricity consumption in Europe was down 30%, Johan Sigvardsson, power price analyst at Swedish utility Bixia AB said.

The prevalence of electric heating systems in France means that power demand is particularly sensitive to cold weather. A cold spell would significantly boost demand and drive record electricity prices in tight markets.

Similar to the last round of shutdowns, it’s use of coal that will probably be hit first if power demand sags, as transition-focused responses gather pace, leaving natural gas mostly shielded from fluctuations in the market.

“We expect that another drop in power demand would again impact coal-fired generation and shield gas power to some extent,” said Carlos Torres Diaz, an analyst at Rystad Energy.

'Unlayering' peak demand could accelerate energy storage adoption

Duration Portfolio Energy Storage aligns layered peak demand with right-sized batteries, enabling peak shaving, gas peaker replacement, and solar-plus-storage synergy while improving grid flexibility, reliability, and T&D deferral through two- to four-hour battery durations.

 

Key Points

An approach that layers battery durations to match peaks, cut costs, replace peakers, and boost grid reliability.

✅ Layers 2- to 4-hour batteries by peak duration

✅ Enables solar-plus-storage and peak shaving

✅ Cuts T&D upgrades, emissions, and fuel costs

 

The debate over energy storage replacing gas-fired peakers has raged for years, but a new approach that shifts the terms of the argument could lead to an acceleration of storage deployments.

Rather than looking at peak demand as a single mountainous peak, some analysts now advocate a layered approach that allows energy storage to better match peak needs and complement ongoing efforts to improve solar and wind power across the grid.

"You don’t have to have batteries that run to infinity."

Some developers of solar-plus-storage projects, bolstered by cheap batteries, say they can already compete head-to-head with gas-fired peakers. "I can beat a gas peaker anywhere in the country today with a solar-plus-storage power plant," Tom Buttgenbach, president and CEO of developer 8minutenergy Renewables, recently told S&P Global.

Customers are very busy these days and rebate programs need to fit the speed of their life. Participation should be quick, easy, and accessible anywhere.

Others disagree. Storage is not disruptive for generation, but will be disruptive for transmission and distribution, Kris Zadlo, executive vice president and chief development officer at Invenergy, told the audience at a Bloomberg New Energy Finance conference last spring. Invenergy, like many renewable power developers, develops generation, energy storage and transmission projects.

But there is another path that avoids the pitfalls of positions on either end of the all-or-none approach. "Do the analysis of the need itself," Ray Hohenstein, market applications director at Fluence, told Utility Dive. If the need is only two hours in duration, it may be best served by a two-hour battery. "You don’t have to have batteries that run to infinity."

 

Storage vs. fossil fuel peakers

Energy storage has several benefits over traditional fossil fuel peaking plants, Hohenstein said. It is instantaneous, it has no emissions and requires no fuel, and has limited infrastructure needs. It can also help the grid absorb higher levels of renewable generation by soaking up excess output, such as solar power at noon, and many planned storage additions will be paired with solar in the next few years. But the one thing energy storage cannot do, he said, is provide limitless energy.

So, instead of looking at replacing an individual peaker, Hohenstein advocated a "duration portfolio" approach that uses energy storage to shave peak load.

If the need is for 150 MW of resources that will never need to run for more than two hours at a time, then a battery is "quite cheap," significantly less than a four or eight-hour battery, said Hohenstein. "If you fill up your peak by duration layer, it could be more cost effective."

 

NREL research driver

Fluence’s approach is informed by research by Paul Denholm and Robert Margolis at the National Renewable Energy Laboratory (NREL), released last spring.

The NREL researchers looked at the California market where they said 11 GW of fossil fuel capacity is expected to be retired by 2029 because of new once-through-cooling requirements that are taking effect. A lot of that capacity is peaking capacity and, according to NREL’s analysis, a large fraction could be replaced with four-hour energy storage, assuming continued storage cost reductions and growth in solar installations.

The key in NREL’s research was the level of solar power penetration. There is a "synergistic" relationship between solar penetration and storage deployment, the researchers wrote, and other studies suggest wind and solar could meet 80% of U.S. demand as these trends continue.

Portland General Electric Program Will Transform Hundreds of Homes Into a Virtual Power Plant

PGE Residential Energy Storage Pilot aggregates 525 home batteries into a virtual power plant, enabling distributed energy resources, smart grid control, renewable energy optimization, demand response, and backup power across Portland General Electric's area.

 

Key Points

A PGE program aggregating 525 batteries into a utility-run virtual power plant for renewables support and backup power.

✅ Up to 4 MW aggregated capacity from 525 residential batteries

✅ Monthly credits: $40 ($20 with solar) for grid services

✅ Enhances smart grid, DERs, resilience, and outage backup

 

Portland General Electric Company is set to launch a pilot program that will incentivize installation and connection of 525 residential energy storage batteries that PGE will dispatch, contributing up to four megawatts of energy to PGE's grid. The distributed assets will create a virtual power plant made up of small units that can be operated individually or combined to serve the grid, adding flexibility that supports PGE's transition to a clean energy future. When the program launches this fall, incentives will be available to residential customers across PGE's service area. Rebates will be available to customers within three neighborhoods participating in PGE's Smart Grid Test Bed, and income-qualified customers participating in Energy Trust of Oregon's Solar Within Reach offer.

PGE will study the full benefits of energy storage that these distributed energy assets can provide the grid while also increasing resiliency for each participating customer. PGE will operate and test the benefits of using homes' batteries, each capable of storing 12 to 16 kWh of energy, to optimize the use of renewable energy and grid capabilities. In the event of a power outage, participating customers can rely on them as a backup power resource.

"Our vision for clean energy relies on a smart, integrated grid. One of the ways that we'll achieve that is through creative partnerships and diversified energy resources, including those behind-the-meter," said Larry Bekkedahl, vice president of Grid Architecture, Integration and Systems Operation. "This pilot project will allow PGE to integrate even more intermittent renewable energy and enhance grid capabilities while also giving participating customers peace of mind in the event of an outage."

Energy storage maximizes renewables and the grid, improves power quality

Energy storage, including long-duration energy storage solutions, is vital to help capture and store energy from renewable power sources, such as wind and solar, that are more variable. As a virtual power plant, the residential battery storage pilot will create a single resource that can help the grid balance energy production with energy demand, freeing up the generation resources that are typically held on standby, ready to kick in when the wind doesn't blow or the sun doesn't shine. As a clean energy option that takes the place of standby resources, the virtual power plant also gives customers access to reliable energy, even in the event of system outages.

The test program will also allow PGE to test new smart-grid control devices across its distribution system that will more effectively allow a two-way exchange between PGE and pilot participants. The new controls will more actively manage the way that electricity is distributed across PGE's system to incorporate energy that customers generate, such as through solar panels, while also meeting power demand that is less predictable, such as for charging electric vehicles, supporting EVs for grid stability strategies. The controls will allow PGE to more actively manage power distribution to improve power quality for all customers.

Select rebates and incentives will be available to participants, aligned with electric vehicle programs that encourage transportation electrification

When it launches in fall 2020, participation in the program will be available to residential customers, including:

* Those across PGE's service area who already have or are installing a qualifying battery. Participation will require an application, and in exchange for allowing PGE to operate their battery for grid services, similar to programs where EV owners selling power back for compensation, participating customers will receive a monthly bill credit of $40, or $20 if the battery is charged with solar power.

* Customers across PGE's service area who are participating in the Solar Within Reach offering from Energy Trust of Oregon. Participants will be eligible for a $5,000 instant rebate in addition to the monthly bill credits.

* Those living within the PGE Smart Grid Test Bed who purchase a battery will be eligible for an instant rebate, in addition to the monthly bill credit of $40 or $20, which will allow PGE to test the localized grid impact of having a large concentration of battery storage devices available on one substation and explore interfaces with vehicle-to-grid pilots in the region.

PGE is working with Energy Trust to cost-effectively procure the residential battery storage systems, as utilities invest in advanced storage solutions across the region, by leveraging the existing Solar incentive program infrastructure and trade ally contractor network. Customers who participate in the program will own their battery systems, and rebates will only be available for systems installed by an Energy Trust solar trade ally. The program may also accept customers with a qualifying battery that is was previously installed, following a process to ensure safe operation.

More information about Portland General Electric's energy storage program is available at PortlandGeneral.com/energystorage and will be updated with details about the residential battery storage pilot program.

Electricity use actually increased during 2018 Earth Hour, BC Hydro

Earth Hour BC highlights BC Hydro data on electricity use, energy savings, and participation in the Lower Mainland and Vancouver Island amid climate change and hydroelectric power dynamics.

 

Key Points

BC observance tracking BC Hydro electricity use and conservation during Earth Hour, amid hydroelectric power dominance.

✅ BC Hydro reports rising electricity use during Earth Hour 2018

✅ Savings fell from 2% in 2008 to near zero province-wide

✅ Hydroelectric grid yields low GHG emissions in BC

 

For the first time since it began tracking electricity use in the province during Earth Hour, BC Hydro said customers used more power during the 60-minute period when lights are expected to dim, mirroring all-time high electricity demand seen recently.

The World Wildlife Fund launched Earth Hour in Sydney, Australia in 2007. Residents and businesses there turned off lights and non-essential power as a symbol to mark the importance of combating climate change.

The event was adopted in B.C. the next year and, as part of that, BC Hydro began tracking the megawatt hours saved.

#google#

In 2008, residents and businesses achieved a two per cent savings in electricity use. But since then, BC Hydro says the savings have plummeted.

The event was adopted in B.C. the next year and, as part of that, BC Hydro began tracking the megawatt hours saved.

In 2008, residents and businesses achieved a two per cent savings in electricity use. But since then, BC Hydro says the savings have plummeted, as record-breaking demand in 2021 and beyond changed consumption patterns.

 

Lights on

For Earth Hour this year, which took place 8:30-9:30 p.m. on March 24, BC Hydro says electricity use in the Lower Mainland increased by 0.5 per cent, even as it activated a winter payment plan to help customers manage bills. On Vancouver Island it increased 0.6 per cent.

In the province's southern Interior and northern Interior, power use remained the same during the event.

On Friday, the utility released a report called: "lights out". Why Earth Hour is dimming in BC. which explores the decline of energy savings related to Earth Hour in the province.

The WWF says the way in which hydro companies track electricity savings during Earth Hour is not an accurate measure of participation, and tracking of emerging loads like crypto mining electricity use remains opaque, and noted that more countries than ever are turning off lights for the event.

For 2018, the WWF shifted the focus of Earth Hour to the loss of wildlife across the globe.

BC Hydro says in its report that the symbolism of Earth Hour is still important to British Columbians, but almost all power generation in B.C. is hydroelectric, though recent drought conditions have required operational adjustments, and only accounts for one per cent of greenhouse gas emissions.

UK Anticipates a 16% Decrease in Energy Bills in April

UK Energy Price Cap Cut 2024 signals relief as wholesale gas prices fall; Ofgem price cap drops per Cornwall Insight, aided by LNG supply, mild winter, despite Red Sea tensions and Ukraine conflict impacts.

 

Key Points

A forecast cut to Great Britain's Ofgem price cap as wholesale gas falls, easing typical annual household bills in 2024.

✅ Cap falls from £1,928 to £1,620 in April 2024

✅ Forecast £1,497 in July, then about £1,541 from October

✅ Drivers: lower wholesale gas, LNG supply, mild winter

 

Households in Great Britain are set to experience a significant reduction in energy costs this spring, with bills projected to drop by over £300 annually. This decrease is primarily due to a decline in wholesale gas prices, offering some respite to those grappling with the cost of living crisis.

Cornwall Insight, a well-regarded industry analyst, predicts a 16% reduction in average bills from the previous quarter, potentially reaching the lowest levels since the onset of the Ukraine conflict.

The industry’s price cap, indicative of the average annual bill for a typical household, is expected to decrease from the current £1,928, set earlier this month, to £1,620 in April – a reduction of £308 and £40 less than previously forecasted in December, as ministers consider ending the gas-electricity price link to improve market resilience.

Concerns about escalating tensions in the Red Sea, where Houthi rebels have disrupted global shipping, initially led analysts to fear an increase in wholesale oil prices and subsequent impact on household energy costs.

Contrary to these concerns, oil prices have remained relatively stable, and European gas reserves have been higher than anticipated during a mild winter, with European gas prices returning to pre-Ukraine war levels since November.

Cornwall Insight anticipates that energy prices will continue to be comparatively low through 2024. They predict a further decline to £1,497 for a typical annual bill from July, followed by a slight increase to £1,541 starting in October.

This forecast is a welcome development for Britons who have been dealing with increased expenses across various sectors, from food to utilities, amidst persistently high inflation rates, with energy-driven EU inflation hitting lower-income households hardest across member states.

Energy bills saw a steep rise in 2021, which escalated further due to the Ukraine conflict in 2022, driving up wholesale gas prices. This surge prompted government intervention to subsidize bills, with the UK price cap estimated to cost around £89bn to the public purse, capping costs to a typical household at £2,500.

Cornwall Insight noted that the supply of liquified natural gas to Europe had not been as adversely affected by the Red Sea disruptions as initially feared. Moreover, the UK has been well-supplied with gas from the US, which has become a more significant supplier since the Ukraine war, even as US electricity prices have risen to multi-decade highs. Contributing factors also include lower gas prices in Asia, mild weather, and robust gas availability.

Craig Lowrey, a principal consultant at Cornwall Insight, remarked that concerns about Red Sea events driving up energy prices have not materialized, allowing households to expect a reduction in prices.

On Monday, the next-month wholesale gas price dropped by 4% to 65p a therm.

However, Lowrey cautioned that a complete return to pre-crisis energy bill levels remains unlikely due to ongoing market impacts from shifting away from Russian energy sources and persistent geopolitical tensions, as well as policy changes such as Britain’s Energy Security Bill shaping market reforms.

Richard Neudegg, director of regulation at Uswitch, welcomed the potential further reduction of the price cap in April. However, he pointed out that this offers little solace to households currently struggling with high winter energy costs during the winter. Neudegg urged Ofgem, the energy regulator, to prompt suppliers to reintroduce more competitive and affordable fixed-price deals.
