When it comes to heating sources, a lot of homeowners won't consider electric heat. But a new company in Saco is hoping to change that.

Thermal Energy Storage of Maine is promoting electric thermal storage systems. They say the devices can provide as much as sixty percent of a home's heating needs, and do it for less money than oil.

The units are filled with heavy ceramic bricks, sandwiched between electric coils. They heat up to 1,100 degrees, and then radiate the heat for hours.

Sam Zaitlin, President of Thermal Energy Storage, says the devices are designed to use what is called off-peak power. That means they heat up at night when electricity is much cheaper.

Special arrangements with the electric company are needed for that, but Zaitlin says both Bangor Hydro and Central Maine Power already offer the service. He says the units are common in a number of other states, in Canada and in Europe, but are not well known in Maine.

He says this can be another way to reduce the state's dependence on foreign oil.

"Right now our game plan is to offer these units, beginning the first quarter of 2011 with a locked in electricity price in the range, the equivalent range of 2.45 to 250 a gallon oil. Locked in two years at a time," said Zaitlin.

Zaitlin says the electric heating units are an ideal companion to Maine's growing number of wind farms. He says the state's current energy plan calls for three thousand megawatts of wind power by 2020.

Planning for Toronto?s Growing Electricity Needs

Toronto Grid Upgrade expands electricity capacity and reliability with new substations, upgraded transmission lines, and integrated renewable energy, supporting EV growth, sustainability goals, and resilient power for Toronto's growing residential and commercial sectors.

 

Key Points

A joint plan to boost grid capacity, add renewables, and improve reliability for Toronto's rising power demand.

✅ New substations and upgraded transmission lines increase capacity

✅ Integrates solar, wind, and storage for cleaner, reliable power

✅ Supports EV adoption, reduces outages, and future-proofs the grid

 

As Toronto's population and economy continue to expand, the surge in electricity demand in the city is also increasing rapidly. In response, the Ontario government, in partnership with the City of Toronto and various stakeholders, has launched an initiative to enhance the electricity infrastructure to meet future needs.

The Ontario Ministry of Energy and the City of Toronto are focusing on a multi-faceted approach that includes upgrades to existing power systems and the integration of renewable energy sources, as well as updated IoT cybersecurity standards for sector devices. This initiative is critical as Toronto looks towards a sustainable future, with projections indicating significant growth in both residential and commercial sectors.

Energy Minister Todd Smith highlighted the urgency of this project, stating, “With Toronto's growing population and dynamic economy, the need for reliable electricity cannot be overstated. We are committed to ensuring that our power systems are not only capable of meeting today's demands but are also future-proofed against the needs of tomorrow.”

The plan involves substantial investments in grid infrastructure to increase capacity and improve reliability. This includes the construction of new substations and the enhancement of old ones, along with the upgrading of transmission lines and exploration of macrogrids to strengthen reliability. These improvements are designed to reduce the frequency and severity of power outages while accommodating new developments and technologies such as electric vehicles, which are expected to place additional demands on the system.

Additionally, the Ontario government is exploring the potential for renewable energy sources, such as rooftop solar grids and wind, to be integrated into the city’s power grid. This shift towards green energy is part of a broader effort to reduce carbon emissions and promote environmental sustainability.

Toronto Mayor John Tory emphasized the collaborative nature of this initiative, stating, “This is a prime example of how collaboration between different levels of government and the private sector can lead to innovative solutions that benefit everyone. By enhancing our electricity infrastructure, we are not only improving the quality of life for our residents but also supporting Toronto's competitive edge as a global city.”

The project also includes a public engagement component, where citizens are encouraged to provide input on the planning and implementation phases. This participatory approach ensures that the solutions developed are in alignment with the needs and expectations of Toronto's diverse communities.

Experts agree that the timing of these upgrades is critical. As urban populations grow, the strain on infrastructure, especially in a powerhouse like Toronto, can lead to significant challenges. Proactive measures, such as those being implemented by Ontario and Toronto, and mirrored by British Columbia's clean energy shift underway on the west coast, are essential in avoiding potential crises and ensuring economic stability.

The success of this initiative could serve as a model for other cities facing similar challenges, highlighting the importance of forward-thinking and cooperation in urban planning and energy management. As Toronto moves forward with these ambitious plans, the eyes of the world, particularly other urban centers, will be watching and learning how to similarly tackle the dual challenges of growth and sustainability, with recent examples like London's newest electricity tunnel demonstrating large-scale grid upgrades.

This strategic approach to managing Toronto's electricity needs reflects a comprehensive understanding of the complexities involved in urban energy systems and a commitment to ensuring a resilient and sustainable future that aligns with Canada's net-zero grid by 2050 goals at the national level for all residents.

Ukraine Resumes Electricity Exports

Ukraine Electricity Exports resume as the EU grid links stabilize; ENTSO-E caps, megawatt capacity, renewables, and infrastructure repairs enable power flows to Moldova, Poland, Slovakia, and Romania despite ongoing Russian strikes.

 

Key Points

Resumed cross-border power sales showing grid stability under ENTSO-E limits and surplus generation.

✅ Exports restart to Moldova; Poland, Slovakia, Romania next.

✅ ENTSO-E cap limits to 400 MW; more capacity under negotiation.

✅ Revenues fund grid repairs after Russian strikes.

 

Ukraine began resuming electricity exports to European countries on Tuesday, its energy minister said, a dramatic turnaround from six months ago when fierce Russian bombardment of power stations plunged much of the country into darkness in a bid to demoralize the population.

The announcement by Energy Minister Herman Halushchenko that Ukraine was not only meeting domestic consumption demands but also ready to restart exports to its neighbors was a clear message that Moscow’s attempt to weaken Ukraine by targeting its infrastructure did not work.

Ukraine’s domestic energy demand is “100%” supplied, he told The Associated Press in an interview, and it has reserves to export due to the “titanic work” of its engineers and international partners.

Russia ramped up infrastructure attacks in September, when waves of missiles and exploding drones destroyed about half of Ukraine's energy system, even as it built lines to reactivate the Zaporizhzhia plant in occupied territory. Power cuts were common across the country as temperatures dropped below freezing and tens of millions struggled to keep warm.

Moscow said the strikes were aimed at weakening Ukraine’s ability to defend itself, and both sides have floated a possible agreement on power plant attacks amid mounting civilian harm, while Western officials said the blackouts that caused civilians to suffer amounted to war crimes. Ukrainians said the timing was designed to destroy their morale as the war marked its first anniversary.


Ukraine had to stop exporting electricity in October to meet domestic needs.

Engineers worked around the clock, often risking their lives to come into work at power plants and keep the electricity flowing. Kyiv’s allies also provided help. In December, U.S. Secretary of State Antony Blinken announced $53 million in bilateral aid to help the country acquire electricity grid equipment, on top of $55 million for energy sector support.

Much more work remains to be done, Halushchenko said. Ukraine needs funding to repair damaged generation and transmission lines, and revenue from electricity exports would be one way to do that.

The first country to receive Ukraine’s energy exports will be Moldova, he said.

Besides the heroic work by engineers and Western aid, warmer temperatures are enabling the resumption of exports by making domestic demand lower, and across Europe initiatives like virtual power plants for homes are helping balance grids. Nationwide consumption was already down at least 30% due to the war, Halushchenko said, with many industries having to operate with less power.

Renewables like solar and wind power also come into play as temperatures rise, taking some pressure off nuclear and coal-fired power plants.

But it’s unclear if Ukraine can keep up exports amid the constant threat of Russian bombardment.

“Unfortunately now a lot of things depend on the war,” Halushchenko said. “I would say we feel quite confident now until the next winter.”

Exports to Poland, Slovakia and Romania are also on schedule to resume, he said.

“Today we are starting with Moldova, and we are talking about Poland, we are talking about Slovakia and Romania,” Halushchenko added, noting that how much will depend on their needs.

“For Poland, we have only one line that allows us to export 200 megawatts, but I think this month we will finish another line which will increase this to an additional 400 MW, so these figures could change,” he said.

Export revenue will depend on fluctuating electricity prices in Europe, where stunted hydro and nuclear output may hobble recovery efforts. In 2022, while Ukraine was still able to export energy, Ukrainian companies averaged 40 million to 70 million euros a month depending on prices, Halushchenko said.

“Even if it’s 20 (million euros) it’s still good money. We need financial resources now to restore generation and transmission lines,” he said.

Ukraine has the ability to export more than the 400 megawatt capacity limit imposed by the European Network of Transmission System Operators for Electricity, or ENTSO-E, and rising EU wind and solar output is reshaping cross-border flows. “We are in negotiations to increase this cap because today we can export even more, we have the necessary reserves in the system,” the minister said.

The current capacity limit is in line with what Ukraine was exporting in September 2022 before Ukraine diverted resources to meet domestic needs amid the Russian onslaught.

Coronavirus puts electric carmakers on alert over lithium supplies

Western Lithium Supply Localization is accelerating as EV battery makers diversify from China, boosting lithium hydroxide sourcing in North America and Europe, amid Covid-19 disruptions and rising prices, with geothermal brines and local processing.

 

Key Points

An industry shift to source lithium and processing near EV hubs, reducing China reliance and supply chain risk.

✅ EV makers seek North American and European lithium hydroxide

✅ Prices rise amid Covid-19 and logistics constraints

✅ New extraction: geothermal and oilfield brine projects

 

The global outbreak of coronavirus will accelerate efforts by western carmakers to localise supplies of lithium for electric car batteries, according to US producer Livent.

The industry was keen to diversify away from China, which produces the bulk of the world’s lithium, a critical material for lithium-ion batteries, said Paul Graves, Livent’s chief executive.

“It’s a conversation that’s starting to happen that was not happening even six months ago,” especially in the US, the former Goldman Sachs banker added.

China produced about 79 per cent of the lithium hydroxide used in electric car batteries last year, according to consultancy CRU, a supply chain that has been disrupted by the virus outbreak and EV shortages in some markets.

Prices for lithium hydroxide rose 3.1 per cent last month, their first increase since May 2018, according to Benchmark Mineral Intelligence, due to the impact of the Covid-19 bug.

Chinese lithium producer Ganfeng Lithium, which supplies major carmakers from Tesla to Volkswagen, said it had raised prices by less than 10 per cent, due to higher production costs and logistical difficulties.

“We can get lithium from lots of places . . . is that really something we’re prepared to rely upon?” Mr Graves said. “People are going to relook at supply chains, including battery recycling initiatives that enhance resilience, and relook at their integrity . . . and they’re going to say is there something we need to do to change our supply chains to make them more shockproof?”

General Motors last week said it was looking to source battery minerals such as lithium and nickel from North America for its new range of electric cars that will use cells made in Ohio by South Korea’s LG Chem.

“Some of these critical minerals could be challenging to obtain; it’s not just cobalt you need to be concerned about but also battery-grade nickel and lithium as well,” said Andy Oury, a lead engineer for batteries at GM. “We’re doing all of this with an eye to sourcing as much of the raw material from North America as possible.”

However, George Heppel, an analyst at CRU, warned it would be difficult to compete with China on costs. “China is always going to be the most competitive place to buy battery raw materials. That’s not likely to change anytime soon,” he said.

Livent, which extracts lithium from brines in northern Argentina, is looking at extracting the mineral from geothermal resources in the US and also wants to build a processing plant in Europe.

The Philadelphia-based company is also working with Canadian start-up E3 Metals to extract lithium from brines in Alberta's oil and gasfields for new projects in Canada.

“We’ll look at doing more in the US and more in Europe,” said Mr Graves, underscoring evolving Canada-U.S. collaboration across EV supply chains.

TransAlta Poised to Finalize Alberta Data Centre Agreement in 2025 

TransAlta Alberta Data Centre integrates AI, cloud computing, and renewable energy, tackling electricity demand, grid capacity, decarbonization, and energy storage with clean power, cooling efficiency, and PPA-backed supply for hyperscale workloads.

 

Key Points

TransAlta Alberta Data Centre is a planned AI facility powered mostly by renewables to meet high electricity demand.

✅ Targets partner exclusivity mid-year; ops 18-24 months post-contract.

✅ Supplies ~90% power via TransAlta; balance from market.

✅ Anchors $3.5B clean energy growth and storage in Alberta.

 

TransAlta Corp., one of Alberta’s leading power producers, is moving toward finalizing agreements with partners to establish a data centre in the province, aligned with AI data center grid integration efforts nationally, aiming to have definitive contracts signed before the end of the year.

CEO John Kousinioris stated during an analyst conference that the company seeks to secure exclusivity with key partners by mid-year, with detailed design plans and final agreements expected by late 2025. Once the contracts are signed, the data centre is anticipated to be operational within 18 to 24 months, a horizon mirrored by Medicine Hat AI grid upgrades initiatives that aim to modernize local systems.

Data centres, which are critical for high-tech industries such as artificial intelligence, consume large amounts of electricity to run and cool servers, a trend reflected in U.S. utility power challenges reporting, underscoring the scale of energy demand. In this context, TransAlta plans to supply around 90% of its partner's energy needs for the facility, with the remainder coming from the broader electricity market.

Alberta has identified data centres as a strategic priority, aiming to see $100 billion in AI-related data centre construction over the next five years. However, the rapid growth of this sector presents challenges for the region’s energy infrastructure. Electricity demand from data centres has already outpaced the available capacity in Alberta’s power grid, intensifying discussions about a western Canadian electricity grid to improve regional reliability, potentially impacting the province’s decarbonization goals.

To address these challenges, TransAlta has adopted a renewable energy investment strategy. The company announced a $3.5 billion growth plan focused primarily on clean electricity generation and storage, as British Columbia's clean energy shift advances across the region, through 2028. By then, more than two-thirds of TransAlta’s earnings are expected to come from renewable power generation, supporting progress toward a net-zero electricity grid by 2050 nationally.

The collaboration between TransAlta and data centre developers represents an opportunity to balance growing energy demand with sustainability goals. By integrating renewable energy generation into data centre operations and broader macrogrid investments, Alberta could move toward a cleaner and more resilient energy future.

Electricity prices in Germany nearly doubled in a year

Germany Energy Price Hikes are driving electricity tariffs, gas prices, and heating costs higher as wholesale markets surge after the Ukraine invasion; households face inflationary pressure despite relief measures and a renewables levy cut.

 

Key Points

Germany Energy Price Hikes reflect surging power and gas tariffs from wholesale spikes, prompting relief measures.

✅ Electricity tariffs to rise 19.5% in Apr-Jun

✅ Gas tariffs up 42.3%; heating and fuel costs soar

✅ Renewables levy ends July; saves €6.6 billion yearly

 

Record prices for electricity and gas in Germany will continue to rise in the coming months, the dpa agency, citing estimates from the consumer portal Verivox.

According to him, electricity suppliers and local utilities, in whose area of ​​responsibility there are 13 million households, made an announcement of tariff increases in April, May and June by 19.5%. Gas tariffs increased by an average of 42.3%.

According to Verivox, electricity prices in Germany have approximately doubled over the year - a pattern seen as European electricity prices rose more than double the EU average - if previously a household with a consumption of 4,000 kWh paid 1,171 euros a year, now the amount has risen to 1,737 euros. Gas prices have risen even more, though European gas prices later returned to pre-Ukraine war levels: last year, a household with a consumption of 20,000 kWh paid 1,184 euros in annual terms, and now it is 2,787 euros. 

Energy costs for the average German household are 52 percent higher than a year ago, adding to EU inflation pressures, according to energy contract sales website Check24. In a press release, the company said the wholesale electricity price was at €122.93 per megawatt-hour in February 2022, compared to €49 this time last year, while in the United States US electricity prices climbed at the fastest pace in 41 years. In addition, electricity prices on the power exchange haven been rising rapidly since Russian troops invaded Ukraine, comparison portal Strom Report said. Costs for heating rose the most, triggered by the high gas price (105 euros per megawatt-hour on the wholesale market) and around 100 USD per barrel of oil – its highest price since 2014. Driving also became more expensive with costs for petrol up 25 percent and diesel 30 percent, Check24 said.

The German government has decided on relief measures for low-income households, including a 200 billion euro energy shield, in response to high consumer energy costs. In July, it will abolish the renewables levy on the power price, saving consumers around €6.6 billion annually. In a reform proposal released this week, the ministry for economy and climate also detailed how it will legally oblige power suppliers to reduce their power bills when the levy is abolished.
