Santa Clara Fire Station powers up with green energy

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.

EU Electricity Market Reform CFDs seek stable prices via contracts for difference, balancing renewables and nuclear, shielding consumers, and boosting competitiveness as France and Germany clash over scope, grid expansion, and hydrogen production.

Key Points

EU framework using contracts for difference to stabilize power prices, support renewables and nuclear, and protect users.

✅ Guarantees strike prices for new low-carbon generation

✅ Balances consumer protection with industrial competitiveness

✅ Disputed scope: nuclear inclusion, grids, hydrogen eligibility

Despite record temperatures this October, Europe is slowly shifting towards winter - its second since the Ukraine war started and prompted Russia to cut gas supplies to the continent amid an energy crisis that has reshaped policy.

After prices surged last winter, when gas and electricity bills “nearly doubled in all EU capitals”, the EU decided to take emergency measures to limit prices.

In March, the European Commission proposed a reform to revamp the electricity market “to boost renewables, better protect consumers and enhance industrial competitiveness”.

However, France and Germany are struggling to find a compromise as rolling back prices is tougher than it appears and the clock is ticking as European energy ministers prepare to meet on 17 October in Luxembourg.

The controversy around CFDs
At the heart of the issue are contracts for difference (CFDs).

By providing a guaranteed price for electricity, CFDs aim to support investment in renewable energy projects.

France - having 56 nuclear reactors - is lobbying for nuclear energy to be included in the CFDs, but this has caught the withering eye of Germany.

Berlin suspects Paris of wanting an exception that would give its industry a competitive advantage and plead that it should only apply to new investments.

France wants ‘to regain control of the price’
The disagreement is at the heart of the bilateral talks in Hamburg, which started on Monday, between the French and German governments.

French President Emmanuel Macron promised “to regain control of the price of electricity, at the French and European level” and outlined a new pricing scheme in a speech at the end of September.

As gas electricity is much more expensive than nuclear electricity, France might be tempted to switch to a national system rather than a European one after a deal with EDF on prices to be more competitive economically.

However, France is "confident" that it will reach an agreement with Germany on electricity market reforms, Macron said on Friday.

Siding with France are other pro-nuclear countries such as Hungary, the Czech Republic and Poland, while Germany can count on the support of Austria, Luxembourg, Belgium and Italy amid opposition from nine EU countries to treating market reforms as a price fix.

But even if a last-minute agreement is reached, the two countries’ struggles over energy are creeping into all current European negotiations on the subject.

Germany wants a massive extension of electricity grids on the continent so that it can import energy; France is banking on energy sovereignty and national production.

France wants to be able to use nuclear energy to produce clean hydrogen, while Germany is reluctant, and so on.

NB Power copper thefts highlight risks at high-voltage substations, with vandalism, fatalities, infrastructure damage, ratepayer costs, and law enforcement alerts tied to metal prices, stolen electricity, and safety concerns across New Brunswick and Nova Scotia.

Key Points

Substation metal thefts causing fatalities, outages, safety risks, and higher costs that impact NB ratepayers.

✅ Spike aligns with copper price near $3 per pound

✅ Fatal break-ins at high-voltage facilities in Bathurst

✅ Repairs, delays, and safety risks for crews, customers

New Brunswick's power utility is urging people to stay away from its substations, saying the valuable copper they contain is proving hard to resist for thieves.

NB Power has seen almost as many incidents of theft and vandalism to its property in April and May of this year, than in all of last year.

In the 2018-2019 fiscal year, the utility recorded 16 cases of theft and/or vandalism.

In April and May, there have already been 13 cases.

One of those was a fatal incident in Bathurst. On April 13, a 41-year-old man was found unresponsive and later died, after breaking into a substation. It was the second fatality linked to a break-in at an NB Power facility in 10 years.

The investigation is still ongoing, but NB Power believes the man was trying to steal copper.

The power utility has been ramping up its efforts -- finding alternate ways to secure its properties, and educate the public -- on the dangers of copper theft, as utilities work to adapt to climate change that can exacerbate severe weather.

“We really, really, really want to stress that if you’re hitting the wrong wire, cutting the wrong wire, breaking in to or cutting fences, a lot of very bad things can happen,” said NB Power spokesperson Marc Belliveau.

In the 2017-2018 fiscal year, there were 24 recorded cases of theft and/or vandalism.

It also comes at a financial cost for NB Power, and ratepayers -- on average, $330,000 a year. About two-thirds of that is copper. The rest is vehicle break-ins or stolen electricity.

“We’ve done analysis,” Belliveau said. “Often the number of break-ins correspond with the price spiking in copper. So, right now, copper’s about $3 a pound. If it was half of that, there might be half as many incidents.”

New Brunswick Public Safety Minister Carl Urquhart says he knows the utility and police are working to dissuade people from the dangers of the theft, and notes that debates around Site C dam stability issues reflect broader infrastructure safety concerns.

“We all know of incident after incident of major injuries and death caused by, simply by, copper,” he said.

Last November, a Dawson Settlement substation was targeted during a major, storm-related power outage in the province.

It meant NB Power had to divert crews to fix and secure the substation, delaying restoration times for some residents and underscoring efforts to improve local reliability across the grid.

Belliveau says that’s “most frustrating.”

“We’re really trying to take a more proactive approach. And certainly, we encourage people that if you know somebody who’s thinking of doing something like that, to really try and talk them out of it because it’s unbelievably dangerous to break in to a substation,” he said.

Nova Scotia Power, connected through the Maritime Link, was not able to provide details on thefts at their substations, but spokesman David Rodenhiser said "the value of the stolen copper is minor in comparison to the risk that’s created when thieves break into our high-voltage electrical substations."

It's not just risky for the people breaking in, and public opposition to projects like Site C underscores broader community safety concerns.

"It also puts the safety of the workers who maintain our substations at risk, because when thieves steal copper, the protective safety devices in the substations don’t work properly," Rodenhiser said.

Additionally, in Nova Scotia, projects like the Maritime Link have advanced regional transmission, and Nova Scotia Power’s copper components have identifying markers, which make that copper difficult to fence. Anyone who buys or sells stolen propery is at risk of criminal charges.

B.C. EV Electrification 2055 projects grid capacity needs doubling to 37 GW, driven by electric vehicles, renewable energy expansion, wind and solar generation, limited natural gas, and policy mandates for zero-emission transportation.

Key Points

A projection that electrifying all B.C. road transport by 2055 would more than double grid demand to 37 GW.

✅ Site C adds 1.1 GW; rest from wind, solar, limited natural gas.

✅ Electricity price per kWh rises 9%, but fuel savings offset.

✅ Significant GHG cuts with 93% renewable grid under Clean Energy Act.

Researchers at the University of Victoria say that if B.C. were to shift to electric power for all road vehicles by 2055, the province would require more than double the electricity now being generated.

The findings are included in a study to be published in the November issue of the Applied Energy journal.

According to co-author and UVic professor Curran Crawford, the team at the university's Pacific Institute for Climate Solutions took B.C.'s 2015 electrical capacity of 15.6 gigawatts as a baseline, and added projected demands from population and economic growth, then added the increase that shifting to electric vehicles would require, while acknowledging power supply challenges that could arise.

They calculated the demand in 2055 would amount to 37 gigawatts, more than double 15.6 gigawatts used in 2015 as a baseline, and utilities warn of a potential EV charging bottleneck if demand ramps up faster than infrastructure.

"We wanted to understand what the electricity requirements are if you want to do that," he said. "It's possible — it would take some policy direction."

B.C. announces $4M in rebates for home and work EV charging stations across the province
The team took the planned Site C dam project into account, but that would only add 1.1 gigawatts of power. So assuming no other hydroelectric dams are planned, the remainder would likely have to come from wind and solar projects and some natural gas.

"Geothermal and biomass were also in the model," said Crawford, adding that they are more expensive electricity sources. "The model we were using, essentially, we're looking for the cheapest options."

The electricity bill, per kilowatt hour, would increase by nine per cent, according to the team's research, but Crawford said getting rid of the gasoline and diesel now used to fuel vehicles could amount to an overall cost saving, especially when combined with zero-emission vehicle incentives available to consumers.

The province introduced a law this year requiring that all new light-duty vehicles sold in B.C. be zero emission by 2040, while the federal 2035 EV mandate adds another policy signal, so the researchers figured 2055 was a reasonable date to imagine all vehicles on the road to be electric.

Crawford said hydrogen-powered vehicles weren't considered in the study, as the model used was already complicated enough, but hydrogen fuel would actually require more electricity for the electrolysis, when compared to energy stored in batteries.

Electric vehicles are approaching a tipping point as faster charging becomes more available — here's why
The study also found that shifting to all-electric ground transportation in B.C. would also mean a significant decrease in greenhouse gas emissions, assuming the Clean Energy Act remains in place, which mandates that 93 per cent of grid electricity must come from renewable resources, whereas nationally, about 18 per cent of electricity still comes from fossil fuels, according to 2019 data. 

"Doing the electrification makes some sense — If you're thinking of spending some money to reduce carbon emissions, this is a pretty cost effective way of doing that," said Crawford.

UAE Nuclear Power Plant launches the Barakah facility, delivering clean electricity to the Middle East under IAEA safeguards amid Gulf tensions, proliferation risks, and debates over renewables, natural gas, grid resilience, and energy security.

Key Points

The UAE Nuclear Power Plant, Barakah, is a civilian facility expected to supply 25% of electricity under IAEA oversight.

✅ Barakah reactors target 25% of national electricity.

✅ Operates under IAEA oversight, no enrichment per US 123 deal.

✅ Raises regional security, proliferation, and environmental concerns.

The United Arab Emirates became the first Arab country to open a nuclear power plant on Saturday, following a crucial step in Abu Dhabi earlier in the project, raising concerns about the long-term consequences of introducing more nuclear programs to the Middle East.

Two other countries in the region — Israel and Iran — already have nuclear capabilities. Israel has an unacknowledged nuclear weapons arsenal and Iran has a controversial uranium enrichment program that it insists is solely for peaceful purposes.

The U.A.E., a tiny nation that has become a regional heavyweight and international business center, said it built the plant to decrease its reliance on the oil that has powered and enriched the country and its Gulf neighbors for decades. It said that once its four units were all running, the South Korean-designed plant would provide a quarter of the country’s electricity, with Unit 1 reaching 100% power as a milestone toward commercial operations.

Seeking to quiet fears that it was trying to build muscle to use against its regional rivals, it has insisted that it intends to use its nuclear program only for energy purposes.

But with Iran in a standoff with Western powers over its nuclear program, Israel in the neighborhood and tensions high among Gulf countries, some analysts view the new plant — and any that may follow — as a security and environmental headache. Other Arab countries, including Saudi Arabia and Iraq, are also starting or planning nuclear energy programs.

The Middle East is already riven with enmities that pit Saudi Arabia and the U.A.E. against Iran, Qatar and Iran’s regional proxies. One of those proxies, the Yemen-based Houthi rebel group, claimed an attack on the Barakah plant when it was under construction in 2017.

And Iran is widely believed to be behind a series of attacks on Saudi oil facilities and oil tankers passing through the Gulf over the last year.

“The UAE’s investment in these four nuclear reactors risks further destabilizing the volatile Gulf region, damaging the environment and raising the possibility of nuclear proliferation,” Paul Dorfman, a researcher at University College London’s Energy Institute, wrote in an op-ed in March.

Noting that the U.A.E. had other energy options, including “some of the best solar energy resources in the world,” he added that “the nature of Emirate interest in nuclear may lie hidden in plain sight — nuclear weapon proliferation.”
But the U.A.E. has said it considered natural gas and renewable energy sources before dismissing them in favor of nuclear energy because they would not produce enough for its needs.

Offering evidence that its intentions are peaceful, it points to its collaborations with the International Atomic Energy Agency, which has reviewed the Barakah project, and the United States, with which it signed a nuclear energy cooperation agreement in 2009 that allows it to receive nuclear materials and technical assistance from the United States while barring it from uranium enrichment and other possible bomb-development activities.

That has not persuaded Qatar, which last year lodged a complaint with the international nuclear watchdog group over the Barakah plant, calling it “a serious threat to the stability of the region and its environment.”

The U.A.E.’s oil exports account for about a quarter of its total gross domestic product. Despite its gusher of oil, it has imported increasing amounts of natural gas in recent years in part to power its energy-intensive desalination plants.

“We proudly witness the start of Barakah nuclear power plant operations, in alignment with the highest international safety standards,” Mohammed bin Zayed, the U.A.E.’s de facto ruler, tweeted on Saturday.

The new nuclear facility, which is in the Gharbiya region on the coast, close to Qatar and Saudi Arabia, is the first of several prospective Middle East nuclear plants, even as Europe reduces nuclear capacity elsewhere. Egypt plans to build a power plant with four nuclear reactors.

Saudi Arabia is also building a civilian nuclear reactor while pursuing a nuclear cooperation deal with the United States, and globally, China's nuclear program remains on a steady development track, though the Trump administration has said it would sign such an agreement only if it includes safeguards against weapons development.

UK Coal-Free Energy Transition highlights the West Burton A closure, accelerating renewable energy, wind, solar, nuclear, energy storage, smart grid upgrades, decarbonization, and net-zero goals while ensuring reliability, affordability, and a just transition for workers.

Key Points

A nationwide shift from coal power to renewables, storage, and nuclear to meet net-zero while maintaining reliability.

✅ West Burton A closure ends UK coal-fired generation

✅ Wind, solar, nuclear, storage strengthen grid resilience

✅ Government backs a just transition and worker retraining

The United Kingdom marks a historic turning point in its energy transition with the closure of the West Burton A Power Station in Nottinghamshire. This coal-fired power plant, once a symbol of the nation's industrial might, has now delivered its final watts of electricity to the grid, signalling the end of coal power generation in the UK.

A Landmark Shift Towards Clean Energy

The closure of West Burton A reflects a dramatic shift in the UK's energy landscape. Coal, the backbone of the UK's power generation for decades, is being phased out in favour of renewable energy sources like wind, solar, and nuclear. This transition aligns with the UK's ambitious net-zero emissions target, which aims to radically decarbonize the country's economy by 2050, though progress can falter, as when low-carbon generation stalled in 2019 amid changing market conditions.

Changing Energy Landscape

In the past, coal-fired power plants provided reliable, on-demand power. However, growing awareness of their significant environmental impact, particularly their contribution to climate change,  has accelerated the move away from coal. The UK government has set clear targets for eliminating coal power generation, and the industry has seen a steady decline as the share of coal fell to record lows in the electricity system.

Renewables Fill the Gap

The remarkable growth of renewable energy sources has enabled the transition away from coal. Wind and solar power, in particular, have experienced rapid development and falling costs, and in 2016 wind generated more electricity than coal for the first time. The UK now boasts substantial offshore and onshore wind farms and extensive solar installations. Additionally, investments in nuclear power and emerging energy storage technologies are increasing the reliability and diversity of the UK's power grid.

Economic and Social Impacts

The closure of the last coal-fired power station carries both economic and social impacts. While this change represents a victory for environmentalists, marked by milestones like a full week without coal power in Britain, the end of coal mining and power generation will lead to job losses in communities traditionally reliant on these industries.  The government has committed to supporting affected regions and facilitating a "just transition" for workers by retraining and creating new opportunities in the clean energy sector.

Global Implications

The UK's commitment to a coal-free future serves as a powerful example for other nations seeking to decarbonize their energy systems, including peers where Alberta's last coal plant closed recently. The nation's experience demonstrates that a transition to renewable energy sources is both possible and necessary. However, it also highlights the importance of careful planning and addressing the social and economic impacts of such a rapid energy revolution.

The Road Ahead

While the closure of West Burton A Power Station marks a historic milestone, the UK's transition to clean energy is far from complete. Maintaining a reliable and affordable energy supply, even as coal-free power records raise questions about energy bills, will require continued investment in renewable energy sources, energy storage, and advanced grid technologies.
