UK Electricity prices hit 10-year high as cheap wind power wanes

Netherlands renewable energy progress highlights rising wind energy and solar power output, delivering 17 billion kWh of green electricity from sustainable sources, yet trailing EU targets, with wind providing 60% and solar 34%.

Key Points

It is the country's growth in green electricity, led by wind and solar, yet short of EU targets at 13.8% of generation.

✅ 17 billion kWh green output; 13.8% of total generation

✅ Wind energy up 16% to 9.6 billion kWh; 60% of green power

✅ Solar power up about 13%; 34% of renewable production

The Netherlands is generating more electricity from sustainable sources as US renewable record 28% in April underscores broader momentum but is still far from reaching its targets, the national statistics office CBS said on Friday.

In total, the Netherlands produced 17 billion kilowatts of green energy last year, a rise of 10% on 2016. Sustainable sources now account for 13.8 per cent of energy generation, even as solar reshapes prices in Northern Europe across the region.

The biggest growth was in wind energy – up 16 per cent to 9.6 billion kWh – or the equivalent of energy for three million households. Wind energy now accounts for 60 per cent of green Dutch power. The amount of solar power, which accounts for 34% of green energy production, rose almost 13 per cent, and Dutch solar outpaces Canada according to recent reports.

In January, European statistics agency Eurostat said the Netherlands is near the bottom of a new table on renewable energy use in Europe. The EU has a target of a fifth of all energy use from green sources by 2020 and – while some countries have reached their own targets, including Germany's 50% clean power milestones – the Dutch, French and Irish need to increase their rates by at least 6%, Eurostat said, and Ireland has set green electricity goals for the next four years to close the gap.

Southeast Electricity Demand Forecast examines how energy efficiency, photovoltaics, electric vehicles, heat pumps, and demand response shape grid needs, stabilize load through 2030, shift peaks, and inform utility planning across the region.

Key Points

An outlook of load shaped by efficiency, solar, EVs, with demand response keeping usage steady through 2030.

✅ Stabilizes regional demand through 2030 under accelerated adoption

✅ Energy efficiency and demand response are primary levers

✅ EVs and heat pumps drive growth post 2030; shift winter peaks

Electricity markets in the Southeast are facing many changes on the customer side of the meter. In a new report released today, we look at how energy efficiency, photovoltaics (solar electricity), electric vehicles, heat pumps, and demand response (shifting loads from periods of high demand) might affect electricity needs in the Southeast.

We find that if all of these resources are pursued on an accelerated basis, electricity demand in the region can be stabilized until about 2030.

After that, demand will likely grow in the following decade because of increased market penetration of electric vehicles and heat pumps, but energy planners will have time to deal with this growth if these projections are borne out. We also find that energy efficiency and demand response can be vital for managing electricity supply and demand in the region and that these resources can help contain energy demand growth, reducing the impact of expensive new generation on consumer wallets.

National trends

This is the second ACEEE report looking at regional electricity demand. In 2016, we published a study on electricity consumption in New England, finding an even more pronounced effect. For New England, with even more aggressive pursuit of energy efficiency and these other resources, consumption was projected to decline through about 2030, before rebounding in the following decade.

These regional trends fit into a broader national pattern. In the United States, electricity consumption has been characterized by flat electricity demand for the past decade. Increased energy efficiency efforts have contributed to this lack of consumption growth, even as the US economy has grown since the Great Recession. Recently, the US Energy Information Administration (EIA – a branch of the US Department of Energy) released data on US electricity consumption in 2016, finding that 2016 consumption was 0.3% below 2015 consumption, and other analysts reported a 1% slide in 2023 on milder weather.

Five scenarios for the Southeast

ACEEE’s new study focuses on the Southeast because it is very different from New England, with warmer weather, more economic growth, and less-aggressive energy efficiency and distributed energy policies than the Northeast. For the Southeast, we examined five scenarios: a business-as-usual scenario; two alternative scenarios with progressively higher levels of energy efficiency, photovoltaics informed by a solar strategy for the South that is emerging regionally, electric vehicles, heat pumps, and demand response; and two scenarios combining high numbers of electric vehicles and heat pumps with more modest levels of the other resources. This figure presents electricity demand for each of these scenarios:

Over the 2016-2040 period, we project that average annual growth will range from 0.1% to 1.0%, depending on the scenario, much slower than historic growth in the region. Energy efficiency is generally the biggest contributor to changes in projected 2040 electricity consumption relative to the business-as-usual scenario, as shown in the figure below, which presents our accelerated scenario that is based on levels of energy efficiency and other resources now targeted by leading states and utilities in the Southeast.

To date, Entergy Arkansas has achieved the annual efficiency savings as a percent of sales shown in the accelerated scenario and Progress Energy (a division of Duke Energy) has nearly achieved those savings in both North and South Carolina. Sixteen states outside the Southeast have also achieved these savings statewide.

The efficiency savings shown in the aggressive scenario have been proposed by the Arkansas PSC. This level of savings has already been achieved by Arizona as well as six other states. Likewise, the demand response savings we model have been achieved by more than 10 utilities, including four in the Southeast. The levels of photovoltaic, electric vehicle, and heat pump penetration are more speculative and are subject to significant uncertainty.

We also examined trends in summer and winter peak demand. Most utilities in the Southeast have historically had peak demand in the summer, often seeing heatwave-driven surges that stress operations across the Eastern U.S., but our analysis shows that winter peaks will be more likely in the region as photovoltaics and demand response reduce summer peaks and heat pumps increase winter peaks.

Why it’s vital to plan broadly

Our analysis illustrates the importance of incorporating energy efficiency, demand response, and photovoltaics into utility planning forecasts as utility trends to watch continue to evolve. Failing to include these resources leads to much higher forecasts, resulting in excess utility system investments, unnecessarily increasing customer electricity rates. Our analysis also illustrates the importance of including electric vehicles and heat pumps in long-term forecasts. While these technologies will have moderate impacts over the next 10 years, they could become increasingly important in the long run.

We are entering a dynamic period of substantial uncertainty for long-term electricity sales and system peaks, highlighted by COVID-19 demand shifts that upended typical patterns. We need to carefully observe and analyze developments in energy efficiency, photovoltaics, electric vehicles, heat pumps, and demand response over the next few years. As these technologies advance, we can create policies to reduce energy bills, system costs, and harmful emissions, drawing on grid reliability strategies tested in Texas, while growing the Southeast’s economy. Resource planners should be sure to incorporate these emerging trends and policies into their long-term forecasts and planning.

Snow-powered nanogenerator harvests static electricity from falling snow using a silicone triboelectric design, enabling energy harvesting, solar panel support during snowfall, and dual-use sensing for weather monitoring and wearable winter sports analytics.

Key Points

A silicone triboelectric device that harvests snowDcharge to generate power and enable sensing.

✅ Triboelectric silicone layer captures charge from falling snow.

✅ Integrates with solar arrays to maintain power during snowfall.

✅ Functions as weather and motion sensor for winter sports.

Scientists from University of California, Los Angeles and McMaster University have invented a nanogenerator that creates electricity from falling snow.

Most Canadians have already seen a mini-version of this, McMaster Prof. Ravi Selvaganapathy told CTV’s Your Morning. “We find that we often get shocked in the winter when it’s dry when we come in into contact with a conductive surface like a doorknob.”

The thin device works by harnessing static electricity: positively-charged, falling snow collides with the negatively-charged silicone device, which produces a charge that’s captured by an electrode.

“You separate the charges and create electricity out of essentially nothing,” Richard Kaner, who holds UCLA’s Dr. Myung Ki Hong Endowed Chair in Materials Innovation and whose lab has explored turning waste into graphene, said in a press release.

“The device can work in remote areas because it provides its own power and does not need batteries or reliance on home storage systems such as the Tesla Powerwall, which store energy for later use,” he said, explaining that the device was 3D printed, flexible and inexpensive to make because of the low cost of silicone.

“It’s also going to be useful in places like Canada, where we get a lot of snow and are pursuing a net-zero grid by 2050 to cut emissions. We can extract energy from the environment,” Selvaganapathy added.

The team, which also included scientists from the University of Toronto, published their findings in Nano Energy journal last year, but a few weeks ago, they revealed the device’s more practical uses.

About 30 per cent of the Earth’s surface is covered by snow each winter, which can significantly limit the energy generated by solar panels, including rooftop solar grids in cold climates.

So the team thought: why not simply harness electricity from the snow whenever the solar panels were covered?

Integrating their device into solar panel arrays could produce a continuous power supply whenever it snows, potentially as part of emerging virtual power plants that aggregate distributed resources, study co-author and UCLA assistant researcher Maher El-Kady explained.

The device also serves as a weather-monitoring station by recording how much snow is falling and from where; as well as the direction and speed of the wind.

The team said they also want to incorporate their device into weather sensors to help them better acquire and transmit electronic signals, supporting initiatives to use AI for energy savings across local grids. They said several Toronto-based companies -- which they couldn’t name -- have expressed interest in partnering with them.

Selvaganapathy said the device would hop on the trend of “sensors being incorporated into what we wear, into our homes and even to detect electricity theft in some markets in order to monitor a lot of the things that are important to us”

But the device’s arguably larger potential use is being integrated into technology to monitor athletes and their performances during winter sports, such as hiking, skiing and cross-country skiing.

Up to now, the movement patterns used during cross-country skiing couldn’t be detected by a smart watch, but this device may be able to.

Scientists such as Kaner believe the technology could usher in a new era of self-monitoring devices to assess an athlete’s performance while they’re running, walking or jumping.

The device is simply a proof of concept and the next step would be figuring out how to generate more electricity and integrate it into all of these potential devices, Selvaganapathy said.

US Electricity Demand Stagnation reflects decoupling from GDP as TVA's IRP revises outlook, with energy efficiency, distributed generation, renewables, and cheap natural gas undercutting coal, reshaping utility business models and accelerating grid modernization.

Key Points

US electricity demand stagnation is flat load growth driven by efficiency, DG, and decoupling from GDP.

✅ Flat sales pressure IOU profits and legacy baseload investments.

✅ Efficiency and rooftop solar reduce load growth and capacity needs.

✅ Utilities must pivot to services, DER orchestration, and grid software.

The US electricity sector is in a period of unprecedented change and turmoil, with emerging utility trends reshaping strategies across the industry today. Renewable energy prices are falling like crazy. Natural gas production continues its extraordinary surge. Coal, the golden child of the current administration, is headed down the tubes.

In all that bedlam, it’s easy to lose sight of an equally important (if less sexy) trend: Demand for electricity is stagnant.

Thanks to a combination of greater energy efficiency, outsourcing of heavy industry, and customers generating their own power on site, demand for utility power has been flat for 10 years, with COVID-19 electricity demand underscoring recent variability and long-run stagnation, and most forecasts expect it to stay that way. The die was cast around 1998, when GDP growth and electricity demand growth became “decoupled”:

This historic shift has wreaked havoc in the utility industry in ways large and small, visible and obscure. Some of that havoc is high-profile and headline-making, as in the recent requests from utilities (and attempts by the Trump administration) to bail out large coal and nuclear plants amid coal and nuclear industry disruptions affecting power markets and reliability.

Some of it, however, is unfolding in more obscure quarters. A great example recently popped up in Tennessee, where one utility is finding its 20-year forecasts rendered archaic almost as soon as they are released.

Falling demand has TVA moving up its planning process

Every five years, the Tennessee Valley Authority (TVA) — the federally owned regional planning agency that, among other things, supplies electricity to Tennessee and parts of surrounding states — develops an Integrated Resource Plan (IRP) meant to assess what it requires to meet customer needs for the next 20 years.

The last IRP, completed in 2015, anticipated that there would be no need for major new investment in baseload (coal, nuclear, and hydro) power plants; it foresaw that energy efficiency and distributed (customer-owned) energy generation would hold down demand.

Even so, TVA underestimated. Just three years later, the Times Free Press reports, “TVA now expects to sell 13 percent less power in 2027 than it did two decades earlier — the first sustained reversal in the growth of electricity usage in the 85-year history of TVA.”

TVA will sell less electricity in 10 years than it did 10 years ago. That is bonkers.

This startling shift in prospects has prompted the company to accelerate its schedule. It will now develop its next IRP a year early, in 2019.

Think for a moment about why a big utility like TVA (serving 9 million customers in seven states, with more than $11 billion in revenue) sets out to plan 20 years ahead. It is investing in extremely large and capital-intensive infrastructure like power plants and transmission lines, which cost billions of dollars and last for decades. These are not decisions to make lightly; the utility wants to be sure that they will still be needed, and will still pay off, for many years to come.

Now think for a moment about what it means for the electricity sector to be changing so fast that TVA’s projections are out of date three years after its last IRP, so much so that it needs to plunge back into the multimillion-dollar, year-long process of developing a new plan.

TVA wanted a plan for 20 years; the plan lasted three.

The utility business model is headed for a reckoning

TVA, as a government-owned, fully regulated utility, has only the goals of “low cost, informed risk, environmental responsibility, reliability, diversity of power and flexibility to meet changing market conditions,” as its planning manager told the Times Free Press. (Yes, that’s already a lot of goals!)

But investor-owned utilities (IOUs), which administer electricity for well over half of Americans, face another imperative: to make money for investors. They can’t make money selling electricity; monopoly regulations forbid it, raising questions about utility revenue models as marginal energy costs fall. Instead, they make money by earning a rate of return on investments in electrical power plants and infrastructure.

The problem is, with demand stagnant, there’s not much need for new hardware. And a drop in investment means a drop in profit. Unable to continue the steady growth that their investors have always counted on, IOUs are treading water, watching as revenues dry up

Utilities have been frantically adjusting to this new normal. The generation utilities that sell into wholesale electricity markets (also under pressure from falling power prices; thanks to natural gas and renewables, wholesale power prices are down 70 percent from 2007) have reacted by cutting costs and merging. The regulated utilities that administer local distribution grids have responded by increasing investments in those grids, including efforts to improve electricity reliability and resilience at lower cost.

But these are temporary, limited responses, not enough to stay in business in the face of long-term decline in demand. Ultimately, deeper reforms will be necessary.

As I have explained at length, the US utility sector was built around the presumption of perpetual growth. Utilities were envisioned as entities that would build the electricity infrastructure to safely and affordably meet ever-rising demand, which was seen as a fixed, external factor, outside utility control.

But demand is no longer rising. What the US needs now are utilities that can manage and accelerate that decline in demand, increasing efficiency as they shift to cleaner generation. The new electricity paradigm is to match flexible, diverse, low-carbon supply with (increasingly controllable) demand, through sophisticated real-time sensing and software.

That’s simply a different model than current utilities are designed for. To adapt, the utility business model must change. Utilities need newly defined responsibilities and new ways to make money, through services rather than new hardware. That kind of reform will require regulators, politicians, and risky experiments. Very few states — New York, California, Massachusetts, a few others — have consciously set off down that path.

Flat or declining demand is going to force the issue

Even if natural gas and renewables weren’t roiling the sector, the end of demand growth would eventually force utility reform.

To be clear: For both economic and environmental reasons, it is good that US power demand has decoupled from GDP growth. As long as we’re getting the energy services we need, we want overall demand to decline. It saves money, reduces pollution, and avoids the need for expensive infrastructure.

But the way we’ve set up utilities, they must fight that trend. Every time they are forced to invest in energy efficiency or make some allowance for distributed generation (and they must always be forced), demand for their product declines, and with it their justification to make new investments.

Only when the utility model fundamentally changes — when utilities begin to see themselves primarily as architects and managers of high-efficiency, low-emissions, multidirectional electricity systems rather than just investors in infrastructure growth — can utilities turn in earnest to the kind planning they need to be doing.

In a climate-aligned world, utilities would view the decoupling of power demand from GDP growth as cause for celebration, a sign of success. They would throw themselves into accelerating the trend.

Instead, utilities find themselves constantly surprised, caught flat-footed again and again by a trend they desperately want to believe is temporary. Unless we can collectively reorient utilities to pursue rather than fear current trends in electricity, they are headed for a grim reckoning.

U.S. Power Grid Cybersecurity combats DHS-FBI flagged threats to energy infrastructure, with PJM Interconnection using ICS/SCADA segmentation, phishing defenses, incident response, and resilience exercises against Russia-linked attacks and pipeline intrusions.

Key Points

Strategies, controls, and training that protect U.S. electric infrastructure from cyber threats and disruptions.

✅ ICS/SCADA network segmentation and zero-trust architecture

✅ Employee phishing drills and incident response playbooks

✅ DOE-led grid exercises and threat intelligence sharing

The joint alert from the FBI and Department of Homeland Security last month warning that Russia was hacking into critical U.S. energy infrastructure, as outlined in six essential reads on Russian hacks from recent coverage, came as no surprise to the nation’s largest grid operator, PJM Interconnection.

“You will never stop people from trying to get into your systems. That isn’t even something we try to do.” said PJM Chief Information Officer, Tom O’Brien. “People will always try to get into your systems. The question is, what controls do you have to not allow them to penetrate? And how do you respond in the event they actually do get into your system?”

PJM is the regional transmission organization for 65 million people, covering 13 states, including Pennsylvania, and Washington D.C.

On a rainy day in early April, about 10 people were working inside PJM’s main control center, outside Philadelphia, closely monitoring floor-to-ceiling digital displays showing real-time information from the electric power sector throughout PJM’s territory in the mid-Atlantic and parts of the midwest, amid reports that hackers accessed control rooms at U.S. utilities.

Donnie Bielak, a reliability engineering manager, was overseeing things from his office, perched one floor up.

“This is a very large, orchestrated effort that goes unnoticed most of the time,” Bielak said. “That’s a good thing.”

But the industry certainly did take notice in late 2015 and early 2016, when hackers successfully disrupted power to the Ukrainian grid. The outages lasted a few hours and affected about 225,000 customers. It was the first publicly-known case of a cyber attack causing major disruptions to a power grid. It was widely blamed on Russia.

One of the many lessons of the Ukraine attacks was a reminder to people who work on critical infrastructure to keep an eye out for odd communications.

“A very large percentage of entry points to attacks are coming through emails,” O’Brien said. “That’s why PJM, as well as many others, have aggressive phishing campaigns. We’re training our employees.”

O’Brien doesn’t want to get into specifics about how PJM deals with cyber threats. But one common way to limit exposure is by having separate systems: For example, industrial controls in a power plant are not connected to corporate business networks, a separation underscored after breaches at U.S. power plants prompted reviews across the sector.

Since 2011, North American grid operators and government agencies have also done large, security exercises every two years. Thousands of people practice how they’d respond to a coordinated physical or cyber event, including rising substation attacks that highlight resilience gaps.

So far, nothing like that has happened in the U.S. It’s possible, but not likely, according to Robert M. Lee, a former military intelligence analyst, who runs the industrial cybersecurity firm Dragos.

“The more complex the system, the harder it is to have a scalable attack,” said Lee, who co-authored a report analyzing the Ukraine attacks. “If you wanted to take out a power generation station– that isn’t the most complex thing. Let’s say you cause an hour of outage. But now you want to cause two months of outages? That’s an exponential increase in effort required.”

For example, he said, it would very difficult for hackers to knock out power to the entire east coast for a long time. But briefly disrupting a major city is easier. That’s the sort of thing that keeps him up at night.

“I worry about an adversary getting into, maybe, Washington D.C.’s portion of the grid, taking down power for 30 minutes,” he said.

The Department of Energy is creating a new office focused on cybersecurity and emergency response, following the U.S. government’s condemnation of power grid hacking by Russia.

Deterrence may be one reason why there has not yet been a major attack on the U.S. grid, said John MacWilliams, a former senior DOE official who’s now a fellow at Columbia University’s Center on Global Energy Policy.

“That’s obviously an act of war,” he said. “We have the capability of responding either through cyber mechanisms or kinetic military.”

In the meantime, small-scale incidents keep happening.

This spring, another cyber attack targeted natural gas pipelines. Four companies shut down their computer systems, just in case, but they say no service was disrupted.

Site C Dam Electricity Demand underscores B.C.'s decarbonization path, enabling electrification of EVs, heat pumps, and industry, aligning with BC Hydro forecasts and 2030/2050 GHG targets to supply dependable, renewable baseload power.

Key Points

Projected clean power tied to Site C, driven by B.C. electrification to meet 2030 and 2050 greenhouse gas targets.

✅ Aligns with 25-30% by 2030 and 55-70% by 2050 GHG cuts

✅ Supports EVs, heat pumps, and industrial electrification

✅ Provides dependable baseload alongside efficiency gains

There are valid reasons not to build the Site C dam. There are also valid reasons to build it. One of the latter is the rapid increase in clean electricity needed to reduce B.C.’s greenhouse gas emissions from burning natural gas, gasoline, diesel and other harmful fossil fuel products.

Although former Premier Christy Clark casually avoided near-term emissions targets, Prime Minister Justin Trudeau has set Canadian targets for both 2030 and 2050, and cleaning up Canada's electricity is critical to meeting them. Studies by my research group at Simon Fraser University and other independent analysts show that B.C.’s cost-effective contribution to these national targets requires us to reduce our emissions 25 to 30 per cent by 2030 and 55 to 70 per cent by 2050 — an energy evolution involving, among other things, a much greater use of electricity in buildings, vehicles and industry.

Recent submissions to the Site C hearing have offered widely different estimates of B.C.’s electricity demand in the decade after the project’s completion in 2025, some arguing the dam’s output will be completely surplus to domestic need for years and perhaps decades, even though improved B.C.-Alberta grid links could help balance regional demand. Some of this variation in demand forecasts is understandable. Industrial demand is especially difficult to predict, dependent as it is on global economic conditions and shifting trade relations. And there are legitimate uncertainties about B.C. Hydro’s ability to reduce electricity demand by promoting efficient products and behaviour through its Power Smart program. But some of the forecasts appear to be deliberate exaggerations, designed to support fixed positions for or against Site C.

Our university-based research team models the energy system changes required to meet national and provincial emissions targets, and we have been comparing estimates of the electricity demand implications. These estimates are produced by academics, as well as by key institutions like B.C. Hydro, the National Energy Board, and the governments of Canada and B.C.

Most electricity forecasts for B.C., including the most recent by B.C. Hydro, do not assume that B.C. reduces its greenhouse gas emissions by 25 to 30 per cent by 2030 and 55 to 70 per cent by 2050. When we adjust Hydro’s forecast for just the low end of these targets, we find that in its latest, August 30, submission to the Site C hearing, which followed the premier’s over-budget go-ahead on the project, Hydro has underestimated the demand for its electricity by about three terawatt-hours in 2025, four in 2030 and 10 in 2035. Hydro’s forecast indicates that it will need the five terawatt-hours from Site C. Our research shows that even if Hydro’s demand forecast is too high, appropriate climate policy nationally and in B.C. will absorb all the electricity the dam can produce soon after its completion.

B.C. Hydro does not forecast electricity demand to 2050. But, studies by us and others show that B.C. electricity demand will be almost double today’s levels if we are to reduce emissions by 55 to 70 per cent, even amid a documented risk of missing the 2050 target, in just over three decades while our population, economy, buildings and equipment grow significantly. Most mid- and small-sized vehicles will be electric. Most buildings will be well insulated and heated by electric resistance or electric heat-pumps, either individually or via district heating systems. And many low temperature industrial applications will be electric.

Aggressive efforts to promote energy efficiency will make an important contribution, such that energy demand will not grow nearly as fast as the economy. But it is delusional to think that humans will stop using energy. Even climate policy scenarios in which we assume unprecedented success with energy efficiency show dramatic increases in the consumption of electricity, this being the most favoured zero-emission form of energy as a replacement for planet-destroying gasoline and natural gas.

The completion of the Site C dam is a complicated and challenging societal choice, and delay-related cost risks highlighted by the premier underscore the stakes. There is unbiased evidence and argument supporting either completion or cancellation. But let’s stick to the unbiased evidence. In the case of our 2030 and 2050 greenhouse gas reduction targets, such evidence shows that we must substantially increase our generation of dependable electricity. If the Site C dam is built, and if we are true to our climate goals, all its electricity will be used in B.C. soon after completion.
