Bechtel completes major power transmission project

HVDC-WISE Project accelerates HVDC technology integration across the European transmission system, delivering a planning toolkit to boost grid reliability, resilience, and interconnectors for renewables and offshore wind amid climate, cyber, and physical threats.

Key Points

EU-funded project delivering tools to integrate HVDC into Europe's grid, improving reliability, resilience, and security.

✅ EU Horizon Europe-backed consortium of 14 partners

✅ Toolkit to assess extreme events and grid operability

✅ Supports interconnectors, offshore wind, and renewables

A partnership of 14 leading European energy industry companies, research organizations and universities has launched a new project to identify opportunities to increase integration of HVDC technology into the European transmission system, echoing calls to invest in smarter electricity infrastructure from abroad.

The HVDC-WISE project, in which the University of Strathclyde is the UK’s only academic partner, is supported by the European Union’s Horizon Europe programme.

The project’s goal is to develop a toolkit for grid developers to evaluate the grid’s performance under extreme conditions and to plan systems, leveraging a digital grid approach that supports coordination to realise the full range of potential benefits from deep integration of HVDC technology into the European transmission system.

The project is focused on enhancing electric grid reliability and resilience while navigating the energy transition. Building and maintaining network infrastructure to move power across Europe is an urgent and complex task, and reducing losses with superconducting cables can play a role, particularly with the continuing growth of wind and solar generation. At the same time, threats to the integrity of the power system are on the rise from multiple sources, including climate, cyber, and physical hazards.

Mutual support

At a time of increasing worries about energy security and as Europe’s electricity systems decarbonise, connections between them to provide mutual support and routes to market for energy from renewables, a dynamic also highlighted in discussions of the western Canadian electricity grid in North America, become ever more important.

In modern power systems, this means making use of High Voltage Direct Current (HVDC) technology.

The earliest forms of technology have been around since the 1960s, but the impact of increasing reliance on HVDC and its ability to enhance a power system’s operability and resilience are not yet fully understood.

Professor Keith Bell, Scottish Power Professor of Future Power Systems at the University of Strathclyde, said:

As an island, HVDC is the only practical way for us to build connections to other countries’ electricity systems. We’re also making use of it within our system, with one existing and more planned Scotland-England subsea link projects connecting one part of Britain to another.

“These links allow us to maximise our use of wind energy. New links to other countries will also help us when it’s not windy and, together with assets like the 2GW substation now in service, to recover from any major disturbances that might occur.

“The system is always vulnerable to weather and things like lightning strikes or short circuits caused by high winds. As dependency on electricity increases, insights from electricity prediction specialists can inform planning as we enhance the resilience of the system.”

Dr Agusti Egea-Alvarez, Senior Lecturer at Strathclyde, said: “HVDC systems are becoming the backbone of the British and European electric power network, either interconnecting countries, or connecting offshore wind farms.

“The tools, procedures and guides that will be developed during HVDC-WISE will define the security, resilience and reliability standards of the electric network for the upcoming decades in Europe.”

Other project participants include Scottish Hydro Electric Transmission, the Supergrid Institute, the Electric Power Research Institute (EPRI) Europe, Tennet TSO, Universidad Pontificia Comillas, TU Delft, Tractebel Impact and the University of Cyprus.

Climate change

Eamonn Lannoye, Managing Director of EPRI Europe, said: “The European electricity grid is remarkably reliable by any standard. But as the climate changes and the grid becomes exposed to more extreme conditions, energy interdependence between regions intensifies and threats from external actors emerge. The new grid needs to be robust to those challenges.”

Juan Carlos Gonzalez, a senior researcher with the SuperGrid Institute which leads the project said: “The HVDC-WISE project is intended to provide planners with the tools and know-how to understand how grid development options perform in the context of changing threats and to ensure reliability.”

HVDC-WISE is supported by the European Union’s Horizon Europe programme under agreement 101075424 and by the UK Research and Innovation Horizon Europe Guarantee scheme.

Enbridge Alberta CCS Project targets carbon capture and storage in Alberta, capturing emissions from industrial emitters to advance net-zero goals, leveraging carbon pricing, regulatory support, and a hub model despite a key partner's exit.

Key Points

A proposed Alberta carbon capture hub by Enbridge to store industrial emissions and support net-zero targets.

✅ Seeks emitters across power, oil and gas, and heavy industry

✅ Backed by carbon pricing, regulation, and net-zero mandates

✅ Faces high capex, storage risk, and anchor-tenant uncertainty

Enbridge Inc., a Canadian energy giant, is digging its heels in on its proposed carbon capture and storage (CCS) project in Alberta. This comes despite the recent withdrawal of Capital Power, a major potential emitter that was expected to utilize the CCS technology. Enbridge maintains the project remains viable, but questions linger about its future viability without a cornerstone anchor.

The CCS project, envisioned as a major carbon capture hub in Alberta, aimed to capture emissions from industrial facilities and permanently store them underground. This technology has the potential to play a significant role in reducing greenhouse gas emissions and mitigating the effects of climate change, alongside grid solutions like bridging the Alberta-B.C. electricity gap that can complement decarbonization efforts.

Capital Power's decision to shelve its $2.4 billion Genesee Generating Station project, which was designed to integrate with the CCS hub, threw a wrench into Enbridge's plans. The Genesee project was expected to be a key source of emissions for capture and storage, and its status is being weighed as Ottawa advances the federal coal plan to phase out unabated coal.

Enbridge, however, remains optimistic. The company cites ongoing discussions with other potential emitters interested in utilizing the CCS technology, amid new funding signals such as the U.S. DOE's $110M for CCUS that highlight momentum. They believe the project holds significant value despite Capital Power's departure.

"We are confident in the long-term viability of the project and continue to actively engage with potential customers," said Enbridge spokesperson Rachel Giroux. "Carbon capture and storage is a critical technology for achieving net-zero emissions, and we believe there is a strong business case for our CCS project."

Enbridge's confidence hinges on several factors. Firstly, they believe there is a growing appetite for CCS technology amongst industrial facilities facing increasing pressure to reduce their carbon footprint. Regulations and carbon pricing mechanisms, including new U.S. EPA power plant rules that test CCS readiness, could further incentivize companies to adopt CCS solutions.

Secondly, Enbridge highlights the potential for capturing emissions from not just power plants but also from other industrial sectors like oil and gas production and clean hydrogen projects in Canada, where reforming processes can generate CO2. This broader application could significantly increase the captured carbon volume and strengthen the project's economic viability.

However, skepticism remains. Critics point to the high upfront costs associated with CCS development and the nascent stage of the technology. They argue that without a guaranteed stream of captured emissions, the project might not be financially sound. Additionally, the long-term safety and effectiveness of large-scale carbon storage solutions remain under scrutiny.

The success of Enbridge's CCS project hinges on attracting new emitters. Replacing Capital Power's contribution will be a significant challenge. Enbridge will need to demonstrate the project's economic viability and navigate the complex regulatory landscape surrounding CCS technology.

The Alberta government's position on CCS is crucial. While the government has expressed support for the technology, the level of financial and regulatory incentives offered will significantly impact investor confidence, especially as the IEA net-zero outlook underscores Canada's need for much more electricity. A clear and stable policy framework will be essential for attracting emitters to the project.

The future of Enbridge's CCS project remains uncertain. Capital Power's withdrawal is a setback, but Enbridge's continued commitment suggests they believe the technology holds promise. Whether they can find enough emitters to justify the project's development will be a critical test. The outcome will have significant implications for the future of CCS technology in Alberta and Canada's broader efforts to achieve net-zero emissions, including Canada-Germany clean energy cooperation that seeks to scale low-carbon fuels.

Rooftop solar grids transform urban infrastructure with distributed generation, photovoltaic panels, smart grid integration and energy storage, cutting greenhouse gas emissions, lowering utility costs, enabling net metering and community solar for low-carbon energy systems.

Key Points

Rooftop solar grids are PV systems on buildings that generate power, cut emissions, and enable smart grid integration.

✅ Lowers utility bills via net metering and demand offset

✅ Reduces greenhouse gases and urban air pollution

✅ Enables resiliency with storage, smart inverters, and microgrids

As urban areas expand and the climate crisis intensifies, cities are seeking innovative ways to integrate renewable energy sources into their infrastructure. One such solution gaining traction is the installation of rooftop solar grids. A recent CBC News article highlights the significant impact of these solar systems on urban environments, showcasing their benefits and the challenges they present.

Harnessing Unused Space for Sustainable Energy

Rooftop solar panels are revolutionizing how cities approach energy consumption and environmental sustainability. By utilizing the often-overlooked space on rooftops, these systems provide a practical solution for generating renewable energy in densely populated areas. The CBC article emphasizes that this approach not only makes efficient use of available space but also contributes to reducing a city's reliance on non-renewable energy sources.

The ability to generate clean energy directly from buildings helps decrease greenhouse gas emissions and, as scientists work to improve solar and wind power, promotes a shift towards a more sustainable energy model. Solar panels absorb sunlight and convert it into electricity, reducing the need for fossil fuels and lowering overall carbon footprints. This transition is crucial as cities grapple with rising temperatures and air pollution.

Economic and Environmental Advantages

The economic benefits of rooftop solar grids are considerable. For homeowners and businesses, installing solar panels can lead to substantial savings on electricity bills. The initial investment in solar technology is often balanced by long-term energy savings and financial incentives, such as tax credits or rebates, and evidence that solar is cheaper than grid electricity in Chinese cities further illustrates the trend toward affordability. According to the CBC report, these financial benefits make solar energy a compelling option for many urban residents and enterprises.

Environmentally, the advantages are equally compelling. Solar energy is a renewable and clean resource, and increasing the number of rooftop solar installations can play a pivotal role in meeting local and national renewable energy targets, as illustrated when New York met its solar goals early in a recent milestone. The reduction in greenhouse gas emissions from fossil fuel energy sources directly contributes to mitigating climate change and improving air quality.

Challenges in Widespread Adoption

Despite the clear benefits, the adoption of rooftop solar grids is not without its challenges. One of the primary hurdles is the upfront cost of installation. While prices for solar panels have decreased over time, the initial financial outlay remains a barrier for some property owners, and regions like Alberta have faced solar expansion challenges that highlight these constraints. Additionally, the effectiveness of solar panels can vary based on factors such as geographic location, roof orientation, and local weather patterns.

The CBC article also highlights the importance of supportive infrastructure and policies for the success of rooftop solar grids. Cities need to invest in modernizing their energy grids to accommodate the influx of solar-generated electricity, and, in the U.S., record clean energy purchases by Southeast cities have signaled growing institutional demand. Furthermore, policies and regulations must support solar adoption, including issues related to net metering, which allows solar panel owners to sell excess energy back to the grid.

Innovative Solutions and Future Prospects

The future of rooftop solar grids looks promising, thanks to ongoing technological advancements. Innovations in photovoltaic cells and energy storage solutions are expected to enhance the efficiency and affordability of solar systems. The development of smart grid technology and advanced energy management systems, including peer-to-peer energy sharing, will also play a critical role in integrating solar power into urban infrastructures.

The CBC report also mentions the rise of community solar projects as a significant development. These projects allow multiple households or businesses to share a single solar installation, making solar energy more accessible to those who may not have suitable rooftops for solar panels. This model expands the reach of solar technology and fosters greater community engagement in renewable energy initiatives.

Conclusion

Rooftop solar grids are emerging as a key element in the transition to sustainable urban energy systems. By leveraging unused rooftop space, cities can harness clean, renewable energy, reduce greenhouse gas emissions, and, as developers learn that more energy sources make better projects, achieve long-term economic savings. While there are challenges to overcome, such as initial costs and regulatory hurdles, the benefits of rooftop solar grids make them a crucial component of the future energy landscape. As technology advances and policies evolve, rooftop solar grids will play an increasingly vital role in shaping greener, more resilient urban environments.

Electricity Security and Firm Capacity underpin reliable supply, balancing variable renewables with grid flexibility via gas plants, nuclear power, hydropower, battery storage, and demand response, safeguarding telework, e-commerce, and critical healthcare operations.

Key Points

Ability to meet demand by combining firm generation and flexible resources, keeping grids stable as renewables grow.

✅ Balances variable renewables with dispatchable generation

✅ Rewards flexibility via capacity markets and ancillary services

✅ Enhances grid stability for critical loads during low demand

The huge disruption caused by the coronavirus crisis, and the low-carbon electricity lessons drawn from it, has highlighted how much modern societies rely on electricity and how firm capacity, such as that provided by nuclear power, is a crucial element in ensuring supply, International Energy Agency (IEA) Executive Director Fatih Birol said.

In a commentary posted on LinkedIn, Birol said: "The coronavirus crisis reminds us of electricity's indispensable role in our lives. It's also providing insights into how that role is set to expand and evolve in the years and decades ahead."

Reliable electricity supply is crucial for teleworking, e-commerce, operating ventilators and other medical equipment, among all its other uses, he said, adding that the hundreds of millions of people who live without any access to electricity are far more vulnerable to disease and other dangers.

"Although new forms of short-term flexibility such as battery storage are on the rise, and initiatives like UK home virtual power plants are emerging, most electricity systems rely on natural gas power plants - which can quickly ramp generation up or down at short notice - to provide flexibility, underlining the critical role of gas in clean energy transitions," Birol said.

"Today, most gas power plants lose money if they are used only from time to time to help the system adjust to shifts in demand. The lower levels of electricity demand during the current crisis are adding to these pressures. Hydropower, an often forgotten workhorse of electricity generation, remains an essential source of flexibility.

"Firm capacity, including nuclear power in countries that have chosen to retain it as an option, is a crucial element in ensuring a secure electricity supply even as soaring electricity and coal use complicate transitions. Policy makers need to design markets that reward different sources for their contributions to electricity security, which can enable them to establish viable business models."

In most economies that have taken strong confinement measures in response to the coronavirus - and for which the IEA has available data - electricity demand has declined by around 15%, largely as a result of factories and businesses halting operations, and in New York City load patterns were notably reshaped during lockdowns. If electricity demand falls quickly while weather conditions remain the same, the share of variable renewables like wind and solar can become higher than normal, and low-emissions sources are set to cover almost all near-term growth.

"With weaker electricity demand, power generation capacity is abundant. However, electricity system operators have to constantly balance demand and supply in real time. People typically think of power outages as happening when surging electricity demand overwhelms supply. But in fact, some of the most high-profile blackouts in recent times took place during periods of low demand," Birol said.

"When electricity from wind and solar is satisfying the majority of demand, and renewables poised to eclipse coal by 2025 are reshaping the mix, systems need to maintain flexibility in order to be able to ramp up other sources of generation quickly when the pattern of supply shifts, such as when the sun sets. A very high share of wind and solar in a given moment also makes the maintenance of grid stability more challenging."

European Power Crisis intensifies as record electricity prices, nuclear output cuts, gas supply strain, heatwave drought, and Rhine shipping bottlenecks hit Germany, France, and Switzerland, tightening winter storage and driving long-term contracts higher.

Key Points

A surge in European power prices from heatwaves, nuclear curbs, Rhine coal limits, and reduced Russian gas supply.

✅ Record year-ahead prices in Germany and France

✅ Nuclear output curbed by warm river cooling limits

✅ Rhine low water disrupts coal logistics and generation

Benchmark power prices in Europe hit fresh records Friday as utilities are increasingly reducing electricity output in western Europe because of the hot weather. 

Next-year contracts in Germany and France, Europe’s biggest economies rose to new highs after Switzerland’s Axpo Holding AG announced curbs at one of its nuclear plants. Electricite de France SA is also reducing nuclear output because of high river temperatures and cooling water restrictions, while Uniper SE in Germany is struggling to get enough coal up the river Rhine. 

Europe is suffering its worst energy crunch in decades, and losing nuclear power is compounding the strain as gas cuts made by Russia in retaliation for sanctions drive a surge in prices. The extreme heat led to the driest July on record in France and is underscoring the impact that a warming climate is having on vital infrastructure.

Water levels on Germany’s Rhine have fallen so low that the river may effectively close soon, impacting supplies of coal to the plants next to it. The Rhone and Garonne in France and the Aare in Switzerland are all too warm to be used to cool nuclear plants effectively, forcing operators to limit energy output under environmental constraints. 

Northwest European weather forecast for the next two weeks:
relates to European Power Hits Records as Plants Start to Buckle in Heat
  
The German year-ahead contract gained as much as 2% to 413 euros a megawatt-hour on the European Energy Exchange AG. The French equivalent rose 1.9% to a record 535 euros. Long-term prices are coming under pressure because producing less power from nuclear and coal will increase the demand for natural gas, which is badly needed to fill storage sites ahead of the winter.  

France to Curb Nuclear Output as Europe’s Energy Crisis Worsens
Uniper SE said on Thursday that two of its coal-fired stations along the Rhine may need to curb output during the next few weeks as transporting coal along the Rhine becomes impossible. 

Plants on the river near Mannheim and Karlsruhe, operated by Grosskraftwerk Mannheim AG and EnBW AG, have previously struggled to source coal because of the shallow water, even as German renewables deliver more electricity than coal and nuclear at times. Both companies said generation hasn’t been affected yet. 

“The low tide is not currently affecting our generation of energy because our plants do not have the need for continuous fresh water,” a Steag GmbH spokesman said on Friday. “But the low tide level can make running plants and transporting coal more complicated than usual.”

The spokesman said though that there is slight reduction in output of about 10 to 15 megawatts, which would equate to a few percent, because of the hot temperatures. “This has been happening over some time now and is a problem for everyone because the plant system is not designed to withstand such hot temperatures,” he said.

European Solar Inverter Demand surges as photovoltaics and residential solar expand during the clean energy transition, driven by high natural gas prices; Germany leads, boosting Enphase and SolarEdge sales for rooftop systems and grid-tied installations.

Key Points

Rising European need for solar inverters, fueled by residential PV growth, high energy costs, and clean energy policies.

✅ Germany leads EU rooftop PV installations

✅ Enphase and SolarEdge see revenue growth

✅ High gas prices and policies spur adoption

Solar equipment makers are expected to post higher quarterly profit, benefiting from strong demand in Europe for critical components that convert energy from the sun into electricity, amid record renewable momentum worldwide.

The continent is emerging as a major market for solar firms as it looks to reduce its dependence on the Russian energy supply and accelerate its clean energy transition, with solar already reshaping power prices in Northern Europe across the region, brightening up businesses of companies such as Enphase Energy (ENPH.O) and SolarEdge Technologies (SEDG.O), which make solar inverters.

Wall Street expects Enphase and SolarEdge to post a combined adjusted net income of $323.8 million for the April-June quarter, a 56.7% jump from a year earlier, even as demand growth slows in the United States.

The energy crisis in Europe is not as acute as last year when Western sanctions on Russia severely crimped supplies, but prices of natural gas and electricity continue to be much higher than in the United States, Raymond James analyst Pavel Molchanov said.

As a result, demand for residential solar keeps growing at a strong pace in the region, with Germany being one of the top markets and solar adoption in Poland also accelerating in recent years across the region.

About 159,000 residential solar systems became operational in the first quarter in Germany amid a solar power boost that reflects policy and demand, a 146% rise from a year earlier, according to BSW solar power association.

Adoption of solar is also helping European homeowners have greater control over their energy costs as fossil fuel prices tend to be more volatile, Morningstar analyst Brett Castelli said.

SolarEdge, which has a bigger exposure to Europe than Enphase, said its first-quarter revenue from the continent more than doubled compared with last year.

In comparison, growth in the United States has been tepid due to lukewarm demand in states like Texas and Arizona where cheaper electricity prices make the economics of residential solar less attractive, even though solar is now cheaper than gas in parts of the U.S. market.

Higher interest rates following the U.S. Federal Reserve's recent actions to tame inflation are also weighing on demand, even as power outage risks rise across the United States.

Analysts also expect weakness in California where a new metering reform reduces the money credited to rooftop solar owners for sending excess power into the grid, underscoring how policy shifts can reshape the sector. The sunshine state accounts for nearly a third of the U.S. residential solar market.

Enphase will report its results on Thursday after the bell, while SolarEdge will release its second-quarter numbers on Aug. 1.
