Xcel Energy has completed work on the infrastructure and launched the remaining software to turn Boulder into what is believed to be the first city ready to plug into the "smart grid."

The Minneapolis-based utility said that the $100 million project included stringing 200 miles of fiber optic cable and installing nearly 16,000 smart meters, which provide information to the company and consumer.

About 4,600 residential and small business transformers in the university city of about 100,000 are tied to the system.

"We've essentially tied all the background pieces together," Xcel Energy spokesman Tom Henley said.

The idea behind a smart electrical grid is to develop a digital, flexible system that provides better flow and use of electricity. Some of the anticipated benefits are lower carbon emissions, coordinating energy use with the availability of power sources such as wind and solar, and savings by avoiding power disruptions.

The company hopes to be able to distribute electricity when and where it's needed, saving millions of dollars and the need for new power plants.

Other companies and communities across the country are installing smart meters and forming partnerships to modernize the electric grid, which has changed little over the last century. The project in Boulder, however, is thought to be the furthest along, said Ed Legge, spokesman for the Edison Electric Institute, a national trade association of shareholder-owned electric companies.

Xcel Energy, working with a consortium of other companies, started work in May 2008. The other companies include Accenture, Current Group, GridPoint, OSIsoft, Schweitzer Engineering Laboratories, SmartSynch and Ventyx.

The utility said the system has already helped it avert four potential long-term outages by getting warnings that transformers were ready to fail.

Henley said the next steps include giving customers with smart meters Internet access to monitor and personalize their energy use. Xcel Energy has at least another 9,000 smart meters ready to be installed for interested customers.

Xcel Energy and its partners have worked with the University of Colorado in Boulder. The university chancellor's residence was turned into a showcase for the effort. Former Chancellor G.P. "Bud" Peterson and his wife, Val, used a laptop computer to set their thermostats and check their energy use. They drove a plug-in electric hybrid SUV provided by Xcel Energy.

The vehicle draws energy from the grid and feeds energy back. The utility is working on converting more vehicles for Boulder County to use.

Henley said several companies and government organizations, many from other countries, have toured Boulder to learn about the project.

South Africa's Eskom could buy less power from wind farms during lockdown

Eskom Wind Power Curtailment reflects South Africa's lockdown-driven drop in electricity demand, prompting grid-balancing measures as Eskom signals reduced IPP procurement from renewable energy projects during low-demand hours, despite guarantees and flexible generation constraints.

 

Key Points

A temporary reduction of wind IPP purchases by Eskom to balance surplus grid capacity during the COVID-19 lockdown slump

✅ Demand drop of 7,500 MW reduced need for variable renewables.

✅ Curtailment likely during low-demand early-morning hours.

✅ IPP revenues protected via contract extensions and guarantees.

 

South African state utility Eskom has told independent wind farms that it could buy less of their power in the coming days, as electricity demand has plummeted during a lockdown, reflecting the Covid-19 impact on renewables worldwide, aimed at curbing the spread of the coronavirus.

Eskom, which is mired in a financial crisis and has struggled to keep the lights on in the past year, said on Tuesday that power demand had dropped by more than 7,500 megawatts since the lockdown started on Friday and that it had taken offline some of its own generators.

The utility supplements its generating capacity, which is mainly derived from coal, by buying power from solar and wind farms, as wind becomes a competitive source of electricity globally, under contracts signed as part of the government’s renewable energy programme.

Spokesman Sikonathi Mantshantsha said Eskom had not yet curtailed power procurement from wind farms but that it had told them, echoing industry warnings on wind investment risk seen by the sector, this could happen “for a few hours a day during the next few days, perhaps until the lockdown is lifted”.

“Most of them are able to feed power into the grid in the early hours of the day. That coincides with the lowest demand period and can highlight curtailment challenges when supply exceeds need. And we now have a lot more capacity than needed,” Mantshantsha said.

During the lockdown imposed by President Cyril Ramaphosa, businesses apart from those deemed “essential services” are closed, mirroring Spanish wind factory closures elsewhere. Many power-hungry mines and furnaces have suspended operations.

Eskom has relatively little of its own “flexible generation” capacity, which can be ramped up or down easily, unlike regions riding a renewables boom in South Australia to export power.

The government has committed to buy up to 200 billion rand ($11.1 billion) of electricity from independent power producers and has issued state guarantees for those purchases.

“They will be compensated for their losses, amid U.S. utility-solar slowdowns being reported - each day lost will be added to their contracts,” Mantshantsha said of the wind farms. “In the end they will not be worse off.”

Crossrail will generate electricity using the wind created by trains

Urban Piezoelectric Energy Textiles capture wind-driven motion on tunnels, bridges, and facades, enabling renewable microgeneration for smart cities with decentralized power, resilient infrastructure, and flexible lamellae sheets that harvest airflow vibrations.

 

Key Points

Flexible piezoelectric sheets that convert urban wind and vibration into electricity on tunnels, bridges, and facades.

✅ Installed on London Crossrail to test airflow energy capture

✅ Flexible lamellae panels retrofit tunnels, bridges, facades

✅ Supports decentralized, resilient urban microgrids

 

Charlotte Slingsby and her startup Moya Power are researching piezo-electric textiles that gain energy from movement, similar to advances like a carbon nanotube energy harvester being explored by materials researchers. It seems logical that Slingsby originally came from a city with a reputation for being windy: “In Cape Town, wind is an energy source that you cannot ignore,” says the 27-year-old, who now lives in London.

Thanks to her home city, she also knows about power failures. That’s why she came up with the idea of not only harnessing wind as an alternative energy source by setting up wind farms in the countryside or at sea, but also for capturing it in cities using existing infrastructure.

 

The problem

The United Nations estimates that by 2050, two thirds of the world’s population will live in cities. As a result, the demand for energy in urban areas will increase dramatically, spurring interest in nighttime renewable technology that can operate when solar and wind are variable. Can the old infrastructure grow fast enough to meet demand? How might we decentralise power generation, moving it closer to the residents who need it?

For a pilot project, she has already installed grids of lamellae-covered plastic sheets in tunnels on London Crossrail routes; the draft in the tube causes the protrusions to flutter, which then generates electricity.

“If we all live in cities that need electricity, we need to look for new, creative ways to generate it, including nighttime solar cells that harvest radiative cooling,” says Slingsby, who studied design and engineering at Imperial College and the Royal College of Art. “I wanted to create something that works in different situations and that can be flexibly adapted, whether you live in an urban hut or a high-rise.”

The yield is low compared to traditional wind power plants and is not able to power whole cities, but Slingsby sees Moya Power as just a single element in a mixture of urban energy sources, alongside approaches like gravity power that aid grid decarbonization.

In the future, Slingsby’s invention could hang on skyscrapers, in tunnels or on bridges – capturing power in the windiest parts of the city, alongside emerging air-powered generators that draw energy from humidity. The grey concrete of tunnels and urban railway cuttings could become our cities’ most visually appealing surfaces...

Opinion: UK Natural Gas, Rising Prices and Electricity

European Energy Market Crisis drives record natural gas and electricity prices across the EU, as LNG supply constraints, Russian pipeline dependence, marginal pricing, and renewables integration expose volatility in liberalised power markets.

 

Key Points

A 2021 surge in European gas and electricity prices from supply strains, demand rebounds, and marginal pricing exposure.

✅ Record TTF gas and day-ahead power prices across Europe

✅ LNG constraints and Russian pipeline dependence tightened supply

✅ Debate over marginal pricing vs regulated models intensifies

 

By Ronan Bolton

The year 2021 was a turbulent one for energy markets across Europe, as Europe's energy nightmare deepened across the region. Skyrocketing natural gas prices have created a sense of crisis and will lead to cost-of-living problems for many households, as wholesale costs feed through into retail prices for gas and electricity over the coming months.

This has created immediate challenges for governments, but it should also encourage us to rethink the fundamental design of our energy markets as we seek to transition to net zero, with many viewing it as a wake-up call to ditch fossil fuels across the bloc.

This energy crisis was driven by a combination of factors: the relaxation of Covid-19 lockdowns across Europe created a surge in demand, while cold weather early in the year diminished storage levels and contributed to increasing demand from Asian economies. A number of technical issues and supply-side constraints also combined to limit imports of liquefied natural gas (LNG) into the continent.

Europe’s reliance on pipeline imports from Russia has once again been called into question, as Gazprom has refused to ride to the rescue, only fulfilling its pre-existing contracts. The combination of these, and other, factors resulted in record prices – the European benchmark price (the Dutch TTF Gas Futures Contract) reached almost €180/MWh on 21 December, with average day-ahead electricity prices exceeding €300/MWh across much of the continent in the following days.

Countries which rely heavily on natural gas as a source of electricity generation have been particularly exposed, with governments quickly put under pressure to intervene in the market.

In Spain the government and large energy companies have clashed over a proposed windfall tax on power producers. In Ireland, where wind and gas meet much of the country’s surging electricity demand, the government is proposing a €100 rebate for all domestic energy consumers in early 2022; while the UK government is currently negotiating a sector-wide bailout of the energy supply sector and considering ending the gas-electricity price link to curb bills.

This follows the collapse of a number of suppliers who had based their business models on attracting customers with low prices by buying cheap on the spot market. The rising wholesale prices, combined with the retail price cap previously introduced by the Theresa May government, led to their collapse.

While individual governments have little control over prices in an increasingly globalised and interconnected natural gas market, they can exert influence over electricity prices as these markets remain largely national and strongly influenced by domestic policy and regulation. Arising from this, the intersection of gas and power markets has become a key site of contestation and comment about the role of government in mitigating the impacts on consumers of rising fuel bills, even as several EU states oppose major reforms amid the price spike.

Given that renewables are constituting an ever-greater share of production capacity, many are now questioning why gas prices play such a determining role in electricity markets.

As I outline in my forthcoming book, Making Energy Markets, a particular feature of the ‘European model’ of liberalised electricity trade since the 1990s has been a reliance on spot markets to improve the efficiency of electricity systems. The idea was that high marginal prices – often set by expensive-to-run gas peaking plants – would signal when capacity limits are reached, providing clear incentives to consumers to reduce or delay demand at these peak periods.

This, in theory, would lead to an overall more efficient system, and in the long run, if average prices exceeded the costs of entering the market, new investments would be made, thus pushing the more expensive and inefficient plants off the system.

The free-market model became established during a more stable era when domestically-sourced coal, along with gas purchased on long-term contracts from European sources (the North Sea and the Netherlands), constituted a much greater proportion of electricity generation.

While prices fluctuated, they were within a somewhat predictable range, and provided a stable benchmark for the long-term contracts underpinning investment decisions. This is no longer the case as energy markets become increasingly volatile and disrupted during the energy transition.

The idea that free price formation in a competitive market, with governments standing back, would benefit electricity consumers and lead to more efficient systems was rooted in sound economic theory, and is the basis on which other major commodity markets, such as metals and agricultural crops, have been organised for decades.

The free-market model applied to electricity had clear limitations, however, as the majority of domestic consumers have not been exposed directly to real-time price signals. While this is changing with the roll-out of smart meters in many countries, the extent to which the average consumer will be willing or able to reduce demand in a predicable way during peak periods remains uncertain.

Also, experience shows that governments often come under pressure to intervene in markets if prices rise sharply during periods of scarcity, thus undermining a basic tenet of the market model, with EU gas price cap strategies floated as one option.

Given that gas continues to play a crucial role in balancing supply and demand for electricity, the options available to governments are limited, illustrating why rolling back electricity prices is harder than it appears for policymakers. One approach would be would be to keep faith with the liberalised market model, with limited interventions to help consumers in the short term, while ultimately relying on innovations in demand side technologies and alternatives to gas as a means of balancing systems with high shares of variable renewables.

An alternative scenario may see a return to old style national pricing policies, involving a move away from marginal pricing and spot markets, even as the EU prepares to revamp its electricity market in response. In the past, in particular during the post-WWII decades, and until markets were liberalised in the 1990s, governments have taken such an approach, centrally determining prices based on the costs of delivering long term system plans. The operation of gas plants and fuel procurement would become a much more regulated activity under such a model.

Many argue that this ‘traditional model’ better suits a world in which governments have committed to long-term decarbonisation targets, and zero marginal cost sources, such as wind and solar, play a more dominant role in markets and begin to push down prices.

A crucial question for energy policy makers is how to exploit this deflationary effect of renewables and pass-on cost savings to consumers, whilst ensuring that the lights stay on.

Despite the promise of storage technologies such as grid-scale batteries and hydrogen produced from electrolysis, aside from highly polluting coal, no alternative to internationally sourced natural gas as a means of balancing electricity systems and ensuring our energy security is immediately available.

This fact, above all else, will constrain the ambitions of governments to fundamentally transform energy markets.

Canada will need more electricity to hit net-zero: IEA report

Canada Clean Electricity Expansion is urged by the IEA to meet net-zero targets, scaling non-emitting generation, electrification, EV demand, and grid integration across provinces to decarbonize industry, buildings, and transport while ensuring reliability and affordability.

 

Key Points

An IEA-backed pathway for Canada to scale non-emitting power, electrification, and grid links to meet net-zero goals.

✅ Double or triple clean generation to replace fossil fuels

✅ Integrate provincial grids to decarbonize dependent regions

✅ Manage EV and heating loads with reliability and affordability

 

Canada will need more electricity capacity if it wants to hit its climate targets, and cleaning up Canada's electricity will be critical, according to a new report from the International Energy Agency (IEA).

The report offers mainly a rosy picture of Canada's overall federal energy policy. But, the IEA draws attention to Canada's increasing future electricity demands, and ultimately, calls on Canada to leverage its non-emitting energy potential and expand renewable energy to hit its climate targets.  

"Canada's wealth of clean electricity and its innovative spirit can help drive a secure and affordable transformation of its energy system and help realize its ambitious goals," stated Fatih Birol, the IEA executive director, in a news release.

The IEA notes that Canada has one of the cleanest energy grids globally, with 83 per cent of electricity coming from non-emitting sources in 2020. But this reflects nationwide progress in electricity to date; the report warns this is not a reason for Canada to rest on its laurels. More electricity will be needed to displace fossil fuels if Canada wants to hit its 2030 targets, the report states, and "even deeper cuts" will be required to reach net-zero by 2050.

"Perhaps more significantly, however, Canada will need to ensure sufficient new clean generation capacity to meet the sizeable levels of electrification that its net-zero targets imply."

Investing in new coal, oil and gas projects must stop to hit climate goals, global energy agency says
The Liberals have promised to create a 100 percent net-zero-emitting electricity system by 2035, with regulating oil and gas emissions and electric car sales as part of the plan; by then, every new light-duty vehicle sold in Canada will be a zero-emission vehicle. The switch from gas guzzlers to plug-in electric vehicles will create new pressures on Canada's electrical grid, as will any turn away from fossil natural gas for home heating.

To meet these challenges, the IEA warns, Canada would need to double or triple the power generated from non-emitting sources compared to today, a shift whose cost could reach $1.4 trillion according to the Canadian Gas Association. 

"Such a shift will require significant regulatory action," the report states, highlighting the need for climate policy for electricity grids to guide implementation, and that will require the federal government to work closely with provinces and territories that control power generation and distribution.

The report notes that the further integration of territorial and provincial electrical grids could allow fossil fuel-dependent provinces, like Alberta, to decarbonize and electrify their economies.

The report, entitled Canada 2022 Energy Policy Review, offers what it calls an "in-depth" look at the commitments Canada has made to transform its energy policy. Since the IEA conducted its last review in 2015, Canada has committed to cutting greenhouse gas emissions by 40 to 45 per cent from 2005 levels by 2030 and achieving net-zero by 2050 under an extended national target.

The IEA is well-known for the production of its annual World Energy Outlook. The Paris-based autonomous intergovernmental organization provides analysis, data, and policy recommendations to promote global energy security and sustainability. Canada is a part of the intergovernmental body, which also conducts peer reviews of its members' energy policy.


Oil and gas emissions rising
Natural Resources Minister Jonathan Wilkinson responded to the report in the IEA news release.

"This report acknowledges Canada's ambitious efforts and historic investments to develop pathways to achieve net-zero emissions by 2050 and ensure a transition that aligns with our shared objective of limiting global warming to 1.5 degrees Celsius," Wilkinson's statement read.

The report notes that — despite that objective — absolute emissions from Canadian oil and gas extraction went up 26 per cent between 2000 and 2019, largely from increased production.

"Canada will need to reconcile future growth in oil sands production with increasingly strict greenhouse gas requirements," the report states.

On the plus side, the IEA found emissions per barrel of oilsands crude have decreased by 20 per cent in the last decade from technical and operational improvements.

The improving carbon efficiency of the oilsands is a "trend that is expected to continue at even higher rates," said Ben Brunnen, vice-president of oilsands, fiscal and economic policy at the Canadian Association of Petroleum Producers.

That may become important, the IEA report notes, as energy investors and buyers look for low-carbon assets and more countries adopt net-zero policies.

Further innovation, such as carbon capture and storage, could help to turn things around for Canada's oil patch, the report says. The Liberals have also said they will place a hard cap on oil and gas emissions from production, but that does not include the burning of the fossil fuels. 

In 2021, the IEA released a report that determined to achieve net-zero by 2050, among many steps, investments needed to end in coal mines, oil and gas wells. Thursday's report, however, made no mention of that, which disappointed at least one environmental group.

"A glaring omission was that this assessment says nothing about production. We know that the most important thing we can do is to stop using and producing oil and gas," said Julia Levin, a senior climate and energy program manager at Environmental Defence.

"And yet that was absent from this report, and that really is a glaring omission, which is completely out of line with their [the IEA's] own work."

EPA, New Taipei spar over power plant

Shenao Power Plant Controversy intensifies as the EPA, Taipower, and New Taipei officials clash over EIA findings, a marine conservation area, fisheries, public health risks, and protests against a coal-fired plant in Rueifang.

 

Key Points

Dispute over coal plant EIA, marine overlap, and health risks, pitting EPA and Taipower against New Taipei and residents.

✅ EPA approved EIA changes; city cites marine conservation conflict

✅ Rueifang residents protest; 400+ signatures, wardens oppose

✅ Debate centers on fisheries, public health, and coal plant impacts

 

The controversy over the Shenao Power Plant heated up yesterday as Environmental Protection Administration (EPA) and New Taipei City Government officials quibbled over the project’s potential impact on a fisheries conservation area and other issues, mirroring New Hampshire hydropower clashes seen elsewhere.

State-run Taiwan Power Co (Taipower) wants to build a coal-fired plant on the site of the old Shenao plant, which was near Rueifang District’s (瑞芳) Shenao Harbor.

The company’s original plan to build a new plant on the site passed an environmental impact assessment (EIA) in 2006, similar to how NEPA rules function in the US, and the EPA on March 14 approved the firm’s environmental impact difference analysis report covering proposed changes to the project.

That decision triggered widespread controversy and protests by local residents, environmental groups and lawmakers, echoing enforcement disputes such as renewable energy pollution cases reported in Maryland.

The controversy reached a new peak after New Taipei City Mayor Eric Chu on Tuesday last week posted on Facebook that construction of wave breakers for the project would overlap with a marine conservation area that was established in November 2014.

The EPA and Taipower chose to ignore the demarcation lines of the conservation area, Chu wrote.

Dozens of residents from Rueifang and other New Taipei City districts yesterday launched a protest at 9am in front of the Legislative Yuan in Taipei, amid debates similar to the Maine power line proposal in the US, where the Health, Environment and Labor Committee was scheduled to review government reports on the project.

More than 400 Rueifang residents have signed a petition against the project, including 17 of the district’s 34 borough wardens, Anti-Shenao Plant Self-Help Group director Chen Chih-chiang said.

Ruifang residents have limited access to information, and many only became aware of the construction project after the EPA’s March 14 decision attracted widespread media coverage, Chen said,

Most residents do not support the project, despite Taipower’s claims to the contrary, Chen said.

New Power Party Executive Chairman Huang Kuo-chang, who represents Rueifang and adjacent districts, said the EPA has shown an “arrogance of power” by neglecting the potential impact on public health and the local ecology of a new coal-fired power plant, even as it moves to revise coal wastewater limits elsewhere.

Huang urged residents in Taipei, Keelung, Taoyaun and Yilan County to reject the project.

If the New Taipei City Government was really concerned about the marine conservation area, it should have spoken up at earlier EIA meetings, rather than criticizing the EIA decision after it was passed, Environmental Protection Administration Deputy Minister Chan Shun-kuei told lawmakers at yesterday’s meeting.

Chan said he wondered if Chu was using the Shenao project for political gain.

However, New Taipei City Environmental Protection Department specialist Sun Chung-wei  told lawmakers that the Fisheries Agency and other experts voiced concerns about the conservation area during the first EIA committee meeting on the proposed changes to the Shenao project on June 15 last year.

Sun was invited to speak to the legislative committee by Chinese Nationalist Party (KMT) Legislator Arthur Chen.

While the New Taipei City Fisheries and Fishing Port Affairs Management Office did not present a “new” opinion during later EIA committee meetings, that did not mean it agreed to the project, Sun said.

However, Chan said that Sun was using a fallacious argument and trying to evade responsibility, as the conservation area had been demarcated by the city government.

Alberta breaks summer electricity record, still far short of capacity

Alberta Electricity Peak Demand surged to 10,638 MW, as AESO reported record summer load from air conditioning, Stampede visitors, and heatwave conditions, with ample generation capacity, stable grid reliability, and conservation urged during 5-7 p.m.

 

Key Points

It is the record summer power load in Alberta, reaching 10,638 MW, with evening conservation urged by AESO.

✅ Record 10,638 MW at 4 pm; likely to rise this week

✅ Drivers: A/C use, heat, Stampede visitors

✅ AESO reports ample capacity; conserve 5-7 pm

 

Consumer use hit 10,638 MW, blowing past a previous high of 10,520 MW set on July 9, 2015, said the Alberta Electric System Operator (AESO).

“We hit a new summer peak and it’s likely we’ll hit higher peaks as the week progresses,” said AESO spokeswoman Tara De Weerd.

“We continue to have ample supply, and as Alberta's electricity future trends toward more wind, our generators are very confident there aren’t any issues.”

That new peak was set at 4 p.m. but De Weerd said it was likely to be exceeded later in the day.

Heightened air conditioner use is normally a major driver of such peak electricity consumption, said De Weerd.

She also said Calgary’s big annual bash is also likely playing a role.

“It’s the beginning of Stampede, you have an influx of visitors so you’ll have more people using electricity,” she said.

Alberta’s generation capacity is 16,420 MW, said the AESO, with wind power increasingly outpacing coal in the province today.

There are no plans, she said, for any of the province’s electricity generators to shut down any of their plants for maintenance or other purposes in the near future as demand rises.

The summer peak is considerably smaller than that reached in the depths of Alberta’s winter.

Alberta’s winter peak usage was recorded last year and was 11,458 MW.

Though the province’s capacity isn’t being strained by the summer heat, De Weerd still encouraged consumers to go easy during the peak use time of the day, between 5 and 7 p.m.

“We don’t have to be running all of our appliances at once,” she said.

Alberta exports an insignificant amount of electricity to Montana, B.C. and Saskatchewan, where demand recently set a new record.

The weather forecast calls for temperatures to soar above 30C through the weekend.

In northern Canada, Yukon electricity demand recently hit a record high, underscoring how extreme temperatures can strain systems.
