Software predicts power output for wind

Scottish Renewable Grid Upgrades address outdated infrastructure, expanding transmission lines, pylons, and substations to move clean energy, meet rising electricity demand, and integrate onshore wind, offshore wind, and battery storage across Scotland.

Key Points

Planned transmission upgrades in Scotland to move clean power via new lines and substations for a low-carbon grid.

✅ Fivefold expansion of transmission lines by 2030

✅ Enables onshore and offshore wind integration

✅ New pylons, substations, and routes face local opposition

Renewable energy in Scotland is being held back by outdated grid infrastructure, industry leaders said, with projects stuck on hold underscoring their warning that new pylons and power lines are needed to "ensure our lights stay on".

Scottish Renewables said new infrastructure is required to transmit the electricity generated by green power sources and help develop "a clean energy future" informed by a broader green recovery agenda.

A new report from the organisation - which represents companies working across the renewables sector - makes the case for electricity infrastructure to be updated, aligning with global network priorities identified elsewhere.

But it comes as electricity firms looking to build new lines or pylons face protests, with groups such as the Strathpeffer and Contin Better Cable Route challenging power giant SSEN over the route chosen for a network of pylons that will run for about 100 miles from Spittal in Caithness to Beauly, near Inverness.

Scottish Renewables said it is "time to be upfront and honest" about the need for updated infrastructure.

It said previous work by the UK National Grid estimated "five times more transmission lines need to be built by 2030 than have been built in the past 30 years, at a cost of more than £50bn".

The Scottish Renewables report said: "Scotland is the UK's renewable energy powerhouse. Our winds, tides, rainfall and longer daylight hours already provide tens of thousands of jobs and billions of pounds of economic activity.

"But we're being held back from doing more by an electricity grid designed for fossil fuels almost a century ago, a challenge also seen in the Pacific Northwest today."

Investment in the UK transmission network has "remained flat, and even decreased since 2017", echoing stalled grid spending trends elsewhere, the report said.

It added: "We must build more power lines, pylons and substations to carry that cheap power to the people who need it - including to people in Scotland.

"Electricity demand is set to increase by 50% in the next decade and double by mid-century, so it's therefore wrong to say that Scottish households don't need more power lines, pylons and substations.

"We need them to ensure our lights stay on, as excess solar can strain networks in the same way consumers elsewhere in the UK need them.

"With abundant natural resources, Scotland's home-grown renewables can be at the heart of delivering the clean energy needed to end our reliance on imported, expensive fossil fuel.

"To do this, we need a national electricity grid capable of transmitting more electricity where and when it is needed, echoing New Zealand's electricity debate as well."

Nick Sharpe, director of communications and strategy at Scottish Renewables, said the current electricity network is "not fit for purpose".

He added: "Groups and individuals who object to the construction of power lines, pylons and substations largely do so because they do not like the way they look.

"By the end of this year, there will be just over 70 months left to achieve our targets of 11 gigawatts (GW) offshore and 12 GW onshore wind.

"To ensure we maximise the enormous socioeconomic benefits this will bring to local communities, we will need a grid fit for the 21st century."

Power-to-gas converts surplus renewable electricity into green hydrogen or synthetic methane via electrolysis and methanation, enabling seasonal energy storage, grid balancing, hydrogen injection into gas pipelines, and decarbonization of heat, transport, and industry.

Key Points

Power-to-gas turns excess renewable power into hydrogen or methane for storage, grid support, and clean fuel.

✅ Enables hydrogen injection into existing natural gas networks

✅ Balances grids and provides seasonal energy storage capacity

✅ Supplies low-carbon fuels for industry, heat, and heavy transport

Last month Denmark’s biggest energy firm, Ørsted, said wind farms it is proposing for the North Sea will convert some of their excess power into gas. Electricity flowing in from offshore will feed on-shore electrolysis plants that split water to produce clean-burning hydrogen, with oxygen as a by-product. That would supply a new set of customers who need energy, but not as electricity. And it would take some strain off of Europe’s power grid as it grapples with an ever-increasing share of hard-to-handle EU wind and solar output on the grid.

Turning clean electricity into energetic gases such as hydrogen or methane is an old idea that is making a comeback as renewable power generation surges and crowds out gas in Europe. That is because gases can be stockpiled within the natural gas distribution system to cover times of weak winds and sunlight. They can also provide concentrated energy to replace fossil fuels for vehicles and industries. Although many U.S. energy experts argue that this “power-to-gas” vision may be prohibitively expensive, some of Europe’s biggest industrial firms are buying in to the idea.

European power equipment manufacturers, anticipating a wave of renewable hydrogen projects such as Ørsted’s, vowed in January that, as countries push for hydrogen-ready power plants across Europe, all of their gas-fired turbines will be certified by next year to run on up to 20 percent hydrogen, which burns faster than methane-rich natural gas. The natural gas distributors, meanwhile, have said they will use hydrogen to help them fully de-carbonize Europe’s gas supplies by 2050.

Converting power to gas is picking up steam in Europe because the region has more consistent and aggressive climate policies and evolving electricity pricing frameworks that support integration. Most U.S. states have goals to clean up some fraction of their electricity supply; coal- and gas-fired plants contribute a little more than a quarter of U.S. greenhouse gas emissions. In contrast, European countries are counting on carbon reductions of 80 percent or more by midcentury—reductions that will require an economywide switch to low-carbon energy.

Cleaning up energy by stripping the carbon out of fossil fuels is costly. So is building massive new grid infrastructure, including transmission lines and huge batteries, amid persistent grid expansion woes in parts of Europe. Power-to-gas may be the cheapest way forward, complementing Germany’s net-zero roadmap to cut electricity costs by a third. “In order to reach the targets for climate protection, we need even more renewable energy. Green hydrogen is perceived as one of the most promising ways to make the energy transition happen,” says Armin Schnettler, head of energy and electronics research at Munich-based electric equipment giant Siemens.

Europe already has more than 45 demonstration projects to improve power-to-gas technologies and their integration with power grids and gas networks. The principal focus has been to make the electrolyzers that convert electricity to hydrogen more efficient, longer-lasting and cheaper to produce.

The projects are also scaling up the various technologies. Early installations converted a few hundred kilowatts of electricity, but manufacturers such as Siemens are now building equipment that can convert 10 megawatts, which would yield enough hydrogen each year to heat around 3,000 homes or fuel 100 buses, according to financial consultancy Ernst & Young.

The improvements have been most dramatic for proton-exchange membrane electrolyzers, which are akin to the fuel cells used in hydrogen vehicles (but optimized to produce hydrogen rather than consume it). The price of proton-exchange electrolyzers has dropped by roughly 40 percent during the past decade, according to a study published in February in Nature Energy. They are also five times more compact than older alkaline electrolysis plants, enabling onsite hydrogen production near gas consumers, and they can vary their power consumption within seconds to operate on fluctuating wind and solar generation.

Many European pilot projects are demonstrating “methanation” equipment that converts hydrogen to methane, too, which can be used as a drop-in replacement for natural gas. Europe’s electrolyzer plants, however, are showing that methanation is not as critical to the power-to-gas vision as advocates long believed. Many electrolyzers are injecting their hydrogen directly into natural gas pipelines—something that U.S. gas firms forbid—and they are doing so without impacting either the gas infrastructure or natural gas consumers.

Europe’s first large-scale hydrogen injection began in eastern Germany in 2013 at a two-megawatt electrolyzer installed by Essen-based power firm E.ON. Germany has since ratcheted up the amount of hydrogen it allows in natural gas lines from an initial 2 percent by volume to 10 percent, in a market where renewables now outpace coal and nuclear in Germany, and other European states have followed suit with their own hydrogen allowances. Christopher Hebling, head of hydrogen technologies at the Freiburg-based Fraunhofer Institute for Solar Energy Systems, predicts that such limits will rise to the 20-percent level anticipated by Europe’s turbine manufacturers.

Moving renewable hydrogen and methane via natural gas pipelines promises to cut the cost of switching to renewable energy. For example, gas networks have storage caverns whose reserves could be tapped to run gas-fired electric generation power plants during periods of low wind and solar output. Hebling notes that Germany’s gas network can store 240 terawatt-hours of energy—roughly 25 times more energy than global power grids can presently store by pumping water uphill to refill hydropower reservoirs. Repurposing gas infrastructure to help the power system could save European consumers 138 billion euros ($156 billion) by 2050, according to Dutch energy consultancy Navigant (formerly Ecofys).

For all the pilot plants and promise, renewable hydrogen presently supplies a tiny fraction of Europe’s gas. And, globally, around 4 percent of hydrogen is supplied via electrolysis, with the bulk refined from fossil fuels, according to the International Renewable Energy Agency.

Power-to-gas is catching up, however. According to the February Nature Energy study, renewable hydrogen already pays for itself in some niche applications, and further electrolyzer improvements will progressively extend its market. “If costs continue to decline as they have done in recent years, power-to-gas will become competitive at large scale within the next decade,” says study co-author Gunther Glenk, an economist at the Technical University of Munich.

Glenk says power-to-gas could scale up faster if governments guaranteed premium prices for renewable hydrogen and methane, as they did to mainstream solar and wind power.

Tim Calver, an energy storage researcher turned consultant and Ernst & Young’s executive director in London, agrees that European governments need to step up their support for power-to-gas projects and markets. Calver calls the scale of funding to date, “not proportionate to the challenge that we face on long-term decarbonization and the potential role of hydrogen.”

BC-Alberta Electricity Restrictions spotlight interprovincial energy tensions, limiting power exports and affecting grid reliability, energy sharing, and climate goals, while raising questions about federal-provincial coordination, smart grids, and storage investments.

Key Points

Policies limiting Alberta's power exports to provinces like BC, prioritizing local demand and affecting grid reliability.

✅ Prioritizes Alberta load over interprovincial power exports

✅ Risks to BC peak demand support and outage resilience

✅ Pressures for federal-provincial coordination and smart-grid investment

In a move that underscores the complexities of Canada's interprovincial energy relationships, the government of British Columbia (B.C.) has formally expressed concerns over recent electricity restrictions imposed by Alberta after it suspended electricity purchase talks with B.C., amid ongoing regional coordination challenges.

Background: Alberta's Electricity Restrictions

Alberta, traditionally reliant on coal and natural gas for electricity generation, has been undergoing a transition towards more sustainable energy sources as it pursues a path to clean electricity in the province.

In response, Alberta introduced restrictions on electricity exports, aiming to prioritize local consumption and stabilize its energy market and has proposed electricity market changes to address structural issues.

B.C.'s Position: Ensuring Energy Reliability and Cooperation

British Columbia, with its diverse energy portfolio and commitment to sustainability, has historically relied on the ability to import electricity from Alberta, especially during periods of high demand or unforeseen shortfalls. The recent restrictions threaten this reliability, prompting B.C.'s government to take action amid an electricity market reshuffle now underway.

B.C. officials have articulated that access to Alberta's electricity is crucial, particularly during outages or times when local generation does not meet demand. The ability to share electricity among provinces ensures a stable and resilient energy system, benefiting consumers and supporting economic activities, including critical minerals operations, that depend on consistent power supply.

Moreover, B.C. has expressed concerns that Alberta's restrictions could set a precedent that might affect future interprovincial energy agreements. Such a precedent could complicate collaborative efforts aimed at achieving national energy goals, including sustainability targets and infrastructure development.

Broader Implications: National Energy Strategy and Climate Goals

The dispute between B.C. and Alberta over electricity exports highlights the absence of a cohesive national energy strategy, as external pressures, including electricity exports at risk, add complexity. While provinces have jurisdiction over their energy resources, the interconnected nature of Canada's power grids necessitates coordinated policies that balance local priorities with national interests.

This situation also underscores the challenges Canada faces in meeting its climate objectives. Transitioning to renewable energy sources requires not only technological innovation but also collaborative policies that ensure energy reliability and affordability across provincial boundaries, as rising electricity prices in Alberta demonstrate.

Potential Path Forward: Dialogue and Negotiation

Addressing the concerns arising from Alberta's electricity restrictions requires a nuanced approach that considers the interests of all stakeholders. Open dialogue between provincial governments is essential to identify solutions that uphold the principles of energy reliability, economic cooperation, and environmental sustainability.

One potential avenue is the establishment of a federal-provincial task force dedicated to energy coordination. Such a body could facilitate discussions on resource sharing, infrastructure investments, and policy harmonization, aiming to prevent conflicts and promote mutual benefits.

Additionally, exploring technological solutions, such as smart grids and energy storage systems, could enhance the flexibility and resilience of interprovincial energy exchanges. Investments in these technologies may reduce the dependency on traditional export mechanisms, offering more dynamic and responsive energy management strategies.

The tensions between British Columbia and Alberta over electricity restrictions serve as a microcosm of the broader challenges facing Canada's energy sector. Balancing provincial autonomy with national interests, ensuring equitable access to energy resources, and achieving climate goals require collaborative efforts and innovative solutions. As the situation develops, stakeholders across the political, economic, and environmental spectrums will need to engage constructively, fostering a Canadian energy landscape that is resilient, sustainable, and inclusive.

Ontario Ultra-Low Overnight Electricity Rate lets eligible customers opt in to 2.4 cents per kWh time-of-use pricing, set by the Ontario Energy Board, as utilities roll out the plan between May 1 and Nov. 1.

Key Points

An OEB-set overnight TOU price of 2.4 cents per kWh for eligible Ontarians, rolling out in phases via local utilities.

✅ 8 of 61 utilities offering rate at May 1 launch

✅ About 20% of 5M customers eligible at rollout

✅ Enova Power delays amid merger integration work

A million households can opt into a new ultra-low overnight electricity rate offered by the Ministry of Energy, as province-wide rate changes begin, but that's just a fraction of customers in Ontario.

Only eight of the 61 provincial power utilities will offer the new rate on the May 1 launch date, following the earlier fixed COVID-19 hydro rate period. The rest have up to six months to get on board.

That means it will be available to 20 percent of the province's five million electricity consumers, the Ministry of Energy confirmed to CBC News.

The Ford government's new overnight pricing was pitched as a money saver for Ontarians, amid the earlier COVID-19 recovery rate that could raise bills, undercutting its existing overnight rate from 7.4 to 2.4 cents per kilowatt hour. Both rates are set by the Ontario Energy Board (OEB).

"We wanted to roll it out to as many people as possible," Kitchener-Conestoga PC MPP Mike Harris Jr. told CBC News. "These companies were ready to go, and we're going to continue to work with our local providers to make sure that everybody can meet that Nov. 1 deadline."

Enova Power — which serves Kitchener, Waterloo, Woolwich, Wellesley and Wilmot — won't offer the reduced overnight rate until the fall, after typical bills rose when fixed pricing ended province-wide.

Enova merger stalls adoption

The power company is the product of the recently merged Kitchener-Wilmot Hydro and Waterloo North Hydro.

The Sept. 1 merger is a major reason Enova Power isn't offering the ultra-low rate alongside the first wave of power companies, said Jeff Quint, innovation and communications manager.

"With mergers, a lot of work goes into them. We have to evaluate, merge and integrate several systems and processes," said Quint.

"We believe that we probably would have been able to make the May 1 timeline otherwise."

The ministry said retroactive pricing wouldn't be available, unlike the off-peak price freeze earlier in the pandemic, and Harris said he doesn't expect the province will issue any rebates to customers of companies that introduce the rates later than May 1.

"These organizations were able to look at rolling things out sooner. But, obviously — if you look at Toronto Hydro, London, Centre Wellington, Hearst, Renfrew — there's a dynamic range of large and smaller-scale providers there. I'm very hopeful the Region of Waterloo folks will be able to work to try and get this done as soon as we can," Harris said.

China 2060 Carbon-Neutral Energy Transition projects tripled electricity, rapid electrification, wind and solar dominance, scalable hydrogen, CCUS, and higher carbon pricing to meet net-zero goals while decarbonizing heavy industry and transport.

Key Points

Shell's outlook for China to reach net zero by 2060 via electrification, renewables, hydrogen, CCUS, and carbon pricing.

✅ Power supply to 60% of energy; generation triples by 2060.

✅ Wind and solar reach 80% of electricity; coal declines sharply.

✅ Hydrogen scales to 17 EJ; CCUS and carbon pricing expand.

China may triple electricity generation to supply 60 percent of the country's total energy under Beijing's carbon-neutral goal by 2060, up from the current 23 per cent, according to Royal Dutch Shell.

Shell is one of the largest global investors in China's energy sector, with business covering gas production, petrochemicals and a retail fuel network. A leading supplier of liquefied natural gas, it has recently expanded into low-carbon business such as hydrogen power and electric vehicle charging.

In a rare assessment of the country's energy sector by an international oil major, Shell said China needed to take quick action this decade to stay on track to reach the carbon-neutrality goal.

China has mapped out plans to reach peak emissions by 2030, and aims to reduce coal power production over the coming years, but has not yet revealed any detailed carbon roadmap for 2060.

This includes investing in a reliable and renewable power system, including compressed air generation, and demonstrating technologies that transform heavy industry using hydrogen, biofuel and carbon capture and utilization.

"With early and systematic action, China can deliver better environmental and social outcomes for its citizens while being a force for good in the global fight against climate change," Mallika Ishwaran, chief economist of Shell International, told a webinar hosted by the company's China business.

Shell expects China's electricity generation to rise three-fold to more than 60 exajoules (EJ) in 2060 from 20 EJ in 2020, even amid power supply challenges reported recently.

Solar and wind power are expected to surpass coal as the largest sources of electricity by 2034 in China, reflecting projections that renewables will eclipse coal globally by mid-decade, versus the current 10 percent, rising to 80 percent by 2060, Shell said.

Hydrogen is expected to scale up to 17 EJ, or equivalent to 580 million tonnes of coal by 2060, up from almost negligible currently, adding over 85 percent of the hydrogen will be produced through electrolysis, supported by PEM hydrogen R&D across the sector, powered by renewable and nuclear electricity, Shell said.

Hydrogen will meet 16 percent of total energy use in 2060 with heavy industry and long-distance transport as top hydrogen users, the firm added.

The firm also expects China's carbon price to rise to 1,300 yuan (CDN$256.36) per tonne in 2060 from 300 yuan in 2030.

Nuclear, on a steady development track, and biomass will have niche but important roles for power generation in the years to come, Shell said.

Electricity generated from biomass, combined with carbon, capture, utilization and storage (CCUS), provide a source of negative emissions for the rest of the energy system from 2053, it added.

Hurricane Michael Statistics track catastrophic wind speed, storm surge, rainfall totals, power outages, evacuations, and fatalities across Florida and the Southeast, detailing Category 4 intensity, Saffir-Simpson scale impacts, and emergency response resources.

Key Points

Hurricane Michael statistics detail wind speed, storm surge, rainfall, outages, and deaths from Category 4 landfall.

✅ 155 mph landfall winds; 14 ft storm surge; 12 in rainfall max

✅ 1.6M without power; 30,000 restoring crews; 6 states emergency

✅ 325k ordered evacuations; 32 deaths; FEMA and Guard deployed

Hurricane Michael, a historic Category 4 storm, struck the Florida Panhandle early Wednesday afternoon, unleashing heavy rain, high winds and a devastating storm surge.

Here is a look at the dangerous storm by the numbers:

155 mph: Wind speed -- nearly the highest possible for a Category 4 hurricane -- with which Michael made landfall near Mexico Beach and Panama City. A hurricane with 157 mph or higher is a Category 5, the strongest on the Saffir-Simpson hurricane wind scale.

129 mph: Peak wind gust reported Wednesday at Tyndall Air Force Base, which is about 12 miles southeast of Panama City, Florida.

32: Number of storm-related deaths attributed to Michael thus far, including an 11-year-old girl who local officials say was killed when part of a metal carport crashed into her family's mobile home in Lake Seminole, Georgia, and a 38-year-old man who was killed when a tree fell onto his moving car in Statesville, North Carolina.

Waves take over a house as Hurricane Michael comes ashore in Alligator Point, Fla., Oct. 10, 2018.

14 feet: Maximum height forecast for the storm surge when Michael's strong winds pushed the ocean water onto land. A storm surge just over 9 feet was reported Wednesday in Apalachicola, Florida.

12 inches: Isolated maximum amount of rain that Michael was expected to dump across the Florida Panhandle and the state's Big Bend region, as well as in southeast Alabama and parts of southwest and central Georgia.

9 inches: Maximum amount of rain that Michael could bring to isolated areas from Virginia to North Carolina.

1.6 million: Number of homes and businesses without power in Florida, Alabama, Georgia, South Carolina, North Carolina and Virginia as of Friday morning, a reminder that extended outages can persist after major disasters.

30,000: Number of workers mobilized from across the country to help restore power, underscoring the risks of field repairs such as line crew injuries during recovery.

6: Number of states that had emergency declarations in anticipation of Michael: Florida, Alabama, Georgia, South Carolina, North Carolina and Virginia.

325,000: Estimated number of people in the storm's path who were told to evacuate by local authorities.

6,000: Approximate number of people who stayed in the roughly 80 shelters across Florida, Alabama, Georgia, South Carolina and North Carolina on Wednesday night, while those sheltering at home were urged to avoid overheated power strips that can spark fires.

3,000: Number of personnel the Federal Emergency Management Agency deployed ahead of landfall, while utilities prepared on-site staffing plans to maintain operations during widespread disruptions.

35: Number of counties in Florida, of the state's 67, where Gov. Rick Scott declared a state of emergency prior to landfall, and grid reliability warnings often underscore systemic risks during national emergencies.

3,500: Number of Florida National Guard troops activated for pre-landfall coordination and planning, with an emphasis on high water and search-and-rescue operations.

600: Number of Florida state troopers assigned to the Panhandle and Big Bend region to assist with response and recovery efforts, including public reminders about downed line safety in affected communities.

500: Number of disaster relief workers that the American Red Cross was sending to affected areas in the Sunshine State.

200: Approximate number of patients being evacuated from at least two hospitals in Florida due to damage from the hurricane, highlighting how critical facilities depend on staff who have raised workforce safety concerns during other crises. Bay Medical Center Sacred Heart in Panama City said in a statement Thursday that its facility was damaged during the storm and thus is transferring more than 200 patients, including 39 who are critically ill, to regional hospitals. Gulf Coast Regional Medical Center, also in Panama City, announced in a statement Thursday that it's evacuating its roughly approximately patients, starting with the most critically ill, "because of the infrastructure challenges in our community."
