Small firm has big ideas on green energy

Medicine Hat Bitcoin Mining Deal delivers 42 MW electricity to Hut 8, enabling blockchain data centres, cryptocurrency mining expansion, and economic diversification in Alberta with low-cost power, land lease, and rapid construction near Unit 16.

Key Points

A pact to supply 42 MW and lease land, enabling Hut 8's blockchain data centres and crypto mining growth in Alberta.

✅ 42 MW electricity from city; land lease near Unit 16

✅ Hut 8 expands to 60.7 MW; blockchain data centres

✅ 100 temporary jobs; 42 ongoing roles in Alberta

The City of Medicine Hat has agreed to supply electricity and lease land to a Toronto-based cryptocurrency mining company, at a time when some provinces are pausing large new crypto loads in a deal that will see $100 million in construction spending in the southern Alberta city.

The city will provide electric energy capacity of about 42 megawatts to Hut 8 Mining Corp., which will construct bitcoin mining facilities near the city's new Unit 16 power plant.

The operation is expected to be running by September and will triple the company's operating power to 60.7 megawatts, Hut 8 said, amid broader investments in new turbines across Canada.

"The signing of the electricity supply agreement and the land lease represents a key component in achieving our business plan for the roll-out of our BlockBox Data Centres in low-cost energy jurisdictions," said the company's board chairman, Bill Tai, in a release.

"[Medicine Hat] offers stable, cost-competitive utility rates and has been very welcoming and supportive of Hut 8's fast-paced growth plans."

In bitcoin mining operations, rows upon rows of power-consuming computers are used to solve mathematical puzzles in exchange for bitcoins and confirm crytopcurrency transactions. The verified transactions are then added to the public ledger known as the blockchain.

Hut 8's existing 18.7-megawatt mining operation at Drumheller, Alta. — a gated compound filled with rows of shipping containers housing the computers — has so far mined 750 bitcoins. Bitcoin was trading Tuesday morning for about $11,180.

Medicine Hat Mayor Ted Clugston says the deal is part of the city's efforts to diversify its economy.

We've made economic development a huge priority down here because we were hit very, very hard by the oil and gas decline," he said, noting that being the generator and vendor of its own electricity puts the city in a uniquely good position.

"Really we're just turning gas into electricity and they're taking that electricity and turning it into blockchain, or ones and zeroes."

Elsewhere in Canada, using more electricity for heat has been urged by green energy advocates, reflecting broader electrification debates.

Hut 8 says construction of the facility is starting right away and will create about 100 temporary jobs. The project is expected to be finished by the third-quarter of this year.

The Medicine Hat mining operation will generate 42 ongoing jobs for electricians, general labourers, systems technicians and security staff.

Space solar power promises wireless energy from orbital solar satellites via microwave or laser power beaming, using photovoltaics and rectennas. NRL and AFRL advances hint at 24-7 renewable power delivery to Earth and airborne drones.

Key Points

Space solar power beams orbital solar energy to Earth via microwaves or lasers, enabling continuous wireless electricity.

✅ Harvests sunlight in orbit and transmits via microwaves or lasers

✅ Provides 24-7 renewable power, independent of weather or night

✅ Enables wireless power for remote sites, grids, and drones

Earlier this year, a small group of spectators gathered in David Taylor Model Basin, the Navy’s cavernous indoor wave pool in Maryland, to watch something they couldn’t see. At each end of the facility there was a 13-foot pole with a small cube perched on top. A powerful infrared laser beam shot out of one of the cubes, striking an array of photovoltaic cells inside the opposite cube. To the naked eye, however, it looked like a whole lot of nothing. The only evidence that anything was happening came from a small coffee maker nearby, which was churning out “laser lattes” using only the power generated by the system as ambitions for cheap abundant electricity gain momentum worldwide.

The laser setup managed to transmit 400 watts of power—enough for several small household appliances—through hundreds of meters of air without moving any mass. The Naval Research Lab, which ran the project, hopes to use the system to send power to drones during flight. But NRL electronics engineer Paul Jaffe has his sights set on an even more ambitious problem: beaming solar power to Earth from space. For decades the idea had been reserved for The Future, but a series of technological breakthroughs and a massive new government research program suggest that faraway day may have finally arrived as interest in space-based solar broadens across industry and government.

Since the idea for space solar power first cropped up in Isaac Asimov’s science fiction in the early 1940s, scientists and engineers have floated dozens of proposals to bring the concept to life, including inflatable solar arrays and robotic self-assembly. But the basic idea is always the same: A giant satellite in orbit harvests energy from the sun and converts it to microwaves or lasers for transmission to Earth, where it is converted into electricity. The sun never sets in space, so a space solar power system could supply renewable power to anywhere on the planet, day or night, as recent tests show we can generate electricity from the night sky as well, rain or shine.

Like fusion energy, space-based solar power seemed doomed to become a technology that was always 30 years away. Technical problems kept cropping up, cost estimates remained stratospheric, and as solar cells became cheaper and more efficient, and storage improved with cheap batteries, the case for space-based solar seemed to be shrinking.

That didn’t stop government research agencies from trying. In 1975, after partnering with the Department of Energy on a series of space solar power feasibility studies, NASA beamed 30 kilowatts of power over a mile using a giant microwave dish. Beamed energy is a crucial aspect of space solar power, but this test remains the most powerful demonstration of the technology to date. “The fact that it’s been almost 45 years since NASA’s demonstration, and it remains the high-water mark, speaks for itself,” Jaffe says. “Space solar wasn’t a national imperative, and so a lot of this technology didn’t meaningfully progress.”

John Mankins, a former physicist at NASA and director of Solar Space Technologies, witnessed how government bureaucracy killed space solar power development firsthand. In the late 1990s, Mankins authored a report for NASA that concluded it was again time to take space solar power seriously and led a project to do design studies on a satellite system. Despite some promising results, the agency ended up abandoning it.

In 2005, Mankins left NASA to work as a consultant, but he couldn’t shake the idea of space solar power. He did some modest space solar power experiments himself and even got a grant from NASA’s Innovative Advanced Concepts program in 2011. The result was SPS-ALPHA, which Mankins called “the first practical solar power satellite.” The idea, says Mankins, was “to build a large solar-powered satellite out of thousands of small pieces.” His modular design brought the cost of hardware down significantly, at least in principle.

Jaffe, who was just starting to work on hardware for space solar power at the Naval Research Lab, got excited about Mankins’ concept. At the time he was developing a “sandwich module” consisting of a small solar panel on one side and a microwave transmitter on the other. His electronic sandwich demonstrated all the elements of an actual space solar power system and, perhaps most important, it was modular. It could work beautifully with something like Mankins' concept, he figured. All they were missing was the financial support to bring the idea from the laboratory into space.

Jaffe invited Mankins to join a small team of researchers entering a Defense Department competition, in which they were planning to pitch a space solar power concept based on SPS-ALPHA. In 2016, the team presented the idea to top Defense officials and ended up winning four out of the seven award categories. Both Jaffe and Mankins described it as a crucial moment for reviving the US government’s interest in space solar power.

They might be right. In October, the Air Force Research Lab announced a $100 million program to develop hardware for a solar power satellite. It’s an important first step toward the first demonstration of space solar power in orbit, and Mankins says it could help solve what he sees as space solar power’s biggest problem: public perception. The technology has always seemed like a pie-in-the-sky idea, and the cost of setting up a solar array on Earth is plummeting, as proposals like a tenfold U.S. solar expansion signal rapid growth; but space solar power has unique benefits, chief among them the availability of solar energy around the clock regardless of the weather or time of day.

It can also provide renewable energy to remote locations, such as forward operating bases for the military, which has deployed its first floating solar array to bolster resilience. And at a time when wildfires have forced the utility PG&E to kill power for thousands of California residents on multiple occasions, having a way to provide renewable energy through the clouds and smoke doesn’t seem like such a bad idea. (Ironically enough, PG&E entered a first-of-its-kind agreement to buy space solar power from a company called Solaren back in 2009; the system was supposed to start operating in 2016 but never came to fruition.)

“If space solar power does work, it is hard to overstate what the geopolitical implications would be,” Jaffe says. “With GPS, we sort of take it for granted that no matter where we are on this planet, we can get precise navigation information. If the same thing could be done for energy, especially as peer-to-peer energy sharing matures, it would be revolutionary.”

Indeed, there seems to be an emerging race to become the first to harness this technology. Earlier this year China announced its intention to become the first country to build a solar power station in space, and for more than a decade Japan has considered the development of a space solar power station to be a national priority. Now that the US military has joined in with a $100 million hardware development program, it may only be a matter of time before there’s a solar farm in the solar system.

West and Central Africa Electricity Access hinges on utility reform, renewable energy, off-grid solar, mini-grids, battery storage, and regional grid integration, lowering costs, curbing energy poverty, and advancing SDG7 with sustainable, reliable power solutions.

Key Points

Expanding reliable power via renewables, grid trade, and off-grid systems to cut energy poverty and unlock inclusive growth.

✅ Utility reform lowers costs and improves service reliability

✅ Regional grid integration enables clean, least-cost power trade

✅ Off-grid solar and mini-grids electrify remote communities

As commodity prices soar and leaders around the world worry about energy shortages and prices of gasoline at the pump, millions of people in Africa still lack access to electricity.  One-half of the people on the continent cannot turn on a fan when temperatures go up, can’t keep food cool, or simply turn the lights on. This energy access crisis must be addressed urgently.

In West and Central Africa, only three countries are on track to give every one of their people access to electricity by 2030. At this slow pace, 263 million people in the region will be left without electricity in ten years.  West Africa has one of the lowest rates of electricity access in the world; only about 42% of the total population, and 8% of rural residents, have access to electricity.

These numbers, some far too big, others far too small, have grave consequences. Electricity is an important step toward enhancing people’s opportunities and choices. Access is key to boosting economic activity and contributes to improving human capital, which, in turn, is an investment in a country’s potential.  

Without electricity, children can’t do their schoolwork at night. Businesspeople can’t get information on markets or trade with each other. Worse, as the COVID-19 pandemic has shown so starkly, limited access to energy constrains hospital and emergency services, further endangering patients and spoiling precious medicine.  

What will it take to power West and Central Africa?  
As the African continent recovers from COVID-19 impacts, now is the critical time to accelerate progress towards universal energy access to drive the region’s economic transformation, promote socio-economic inclusion, and unlock human capital growth. Without reliable access to electricity, the holes in a country’s social fabric can grow bigger, those without access growing disenchanted with inequality.  

Tackling the Africa region’s energy access crisis requires four bold approaches. 

First, this involves making utilities financially viable. Many power providers in the region are cash-strapped, operate dilapidated and aging generation fleet and infrastructure. Therefore, they can’t deliver reliable and affordable electricity to their customers, let alone deliver electricity to those that currently must rely on inadequate alternatives to electricity. Overall, fewer than half of the utilities in Sub-Saharan Africa recover their operating costs, resulting in GDP losses as high as four percent in some countries.

Improving the performance of national utilities and greening their power generation mix is a prerequisite to lowering the costs of supply, thus expanding electricity access to those currently unelectrified, usually lower-income and often remote households. 

In that effort — and this a critical second point — West and Central African countries need to look beyond their borders and further integrate their national utilities and grids to other systems in the region. The region has an abundance of affordable clean energy sources — hydropower in Guinea, Mali, and Cote d’Ivoire; high solar irradiation in the Sahel — but the regional energy market is fragmented. 

Without efficient regional trade, many countries are highly dependent on one or two energy resources and heavily reliant on inefficient, polluting generation sources, requiring fuel imports linked to volatile international oil prices.

The vision of an integrated regional power market in countries of the Economic Community of West African States (ECOWAS) is coming a step closer to reality thanks to an ambitious program of cross-border interconnection projects. If countries take full advantage of this grid, the share of the region’s electricity consumption traded across borders would more than double from 8 percent today to about 17 percent by 2030. Overall, regional power trade could lower the lifecycle cost of West Africa’s power generation system by about 10 percent and provide greener energy by 2030. 

Third, electrification efforts need to be open to private sector investments and innovations, such as renewables like solar energy and battery storage, which have made a tremendous impact in enabling access for millions of poor and underserved households.  Specifically, off-grid solar systems and mini-grids have become a proven reliable way to provide affordable modern electricity services, powering homes in rural communities, healthcare facilities, and schools.

Burkina Faso, which enjoys one of the best solar radiation conditions in the region, is a successful example of leveraging the transformative impact of solar energy and battery storage. With support from the World Bank, the country is deploying solar energy to power its national grid, as well as mini-grids and individual household systems. Solar power with battery storage is competitive in Burkina Faso compared to other technologies and its government was successful in attracting private sector investments to support this technology.

Last, achieving universal electricity access will involve significant commitment from political leaders, especially developing policies and regulations that can attract high-quality investments.  

A significant step in that direction was achieved at the World Bank’s 2020 Annual Meetings with a commitment to set up the Powering Transformation Platform in each African country. Through the platform, each government will set their country-specific vision, goals and metrics, track progress, and explore and exchange innovative ideas and emerging best practices according to their own national energy needs and plans. 

This platform will bring together the elements needed to bring electricity to all in West and Central Africa and help attract new financing.

Over the last 3 years, the World Bank has doubled its investments to increase electricity access rates in Central and West Africa.  We have committed more than $7.8 billion to support 40 electricity access programs, of which more than half directly support new electricity connections. These operations are expected to provide access to 16 million people. The aim is to increase electricity access rates in West and Central Africa from 50 percent today to 64 percent by 2026.

However, World Bank’s financing alone is not enough. Our estimates show that nearly $20 billion are required for universal electrification across Sub-Saharan Africa, aligning with calls to quadruple power investment to meet demand, with about $10 billion annually needed for West and Central Africa. 

Closing the funding gap will require mobilizing traditional and new partners, especially the private sector, which is willing to invest if enabling conditions are in place, as well as philanthropic capital, that can fill in the space in areas not yet commercially attractive. The World Bank is ready to play a catalytical role in leveraging new investments. 

This is vital as less than a decade remains to reach the 2030 SDG7 goal of ensuring electricity for all through affordable, reliable, and modern energy services. As headlines worldwide focus on soaring energy prices in the developed world, we cannot lose sight of the vast populations in Africa that still cannot access basic energy services. This is the true global energy crisis.

Alberta Electricity Market Reform reshapes policy under the UCP, weighing a capacity market versus energy-only design, AESO reliability rules, renewables targets, coal phase-out, carbon pricing, consumer rates, and investment certainty before AUC decisions.

Key Points

Alberta Electricity Market Reform is the UCP plan to reassess capacity vs energy-only, renewables, and carbon pricing.

✅ Reviews capacity market timeline and AESO procurement

✅ Alters subsidies for renewables; slows wind and solar growth

✅ Adjusts industrial carbon levy; audits Balancing Pool losses

Hearings kicked off this week into the future of the province’s electricity market design, amid an electricity market reshuffle pledged by the province, but a high-stakes decision about the industry’s fate — affecting billions of dollars in investment and consumer costs — won’t be made inside the meeting room of the Alberta Utilities Commission.

Instead, it will take place in the office of Jason Kenney, as the incoming premier prepares to pivot away from the seismic reforms to Alberta’s electricity sector introduced by the Notley government.

The United Conservative Party has promised to adopt market-based policies, reflecting changes to how Alberta produces and pays for power, that will reset how the sector operates, from its approach to renewable energy and carbon pricing to re-evaluating the planned transition to an electricity “capacity market.”

“Every ball in electricity is up in the air right now,” Vittoria Bellissimo, of the Industrial Power Consumers Association of Alberta, said Tuesday during a break in the commission hearings.

Industry players are uncertain how quickly the UCP will change direction on power policies, but there’s little doubt Kenney’s government will take a strikingly different approach to the sector that keeps the lights on in Alberta.

“There’s some things they are going to change that are going to impact the electricity industry significantly,” said Duane Reid-Carlson, chief executive of consultancy EDC Associates.

“But I don’t think it’s going to be upheaval. I think the new government will proceed with caution because electricity is the foundation of our economy.”

Alberta’s electricity market has been turned on its head in recent years due to the recession, power prices dropping to near two-decade lows and several transformative policies initiated by the NDP.

The Notley government’s climate plan included an accelerated phase-out of all coal-fired generation and set targets for more renewable energy.

The most significant, but least-understood, move has been the planned shift to an electricity capacity market in 2021.

Under the strategy, generators will no longer solely be paid for the power produced and sold into the market; they will also receive payments for having electricity capacity available to the grid on demand.

The change was recommended by the Alberta Electric System Operator (AESO) as a way to reduce price volatility and provide more reliability than the current energy-only market, which some argue needs more competition to deliver better outcomes.

The independent system operator and industry officials have spent more than two years planning the transition since the switch was announced in late 2016. Proposed rules for the new system, outlining market changes, are now being discussed at the Alberta Utilities Commission hearings.

However, there is no ironclad guarantee the system remake will go ahead following the UCP’s election victory last week — amid calls to scrap the overhaul from a Calgary retailer — it plans to study the issue further — while other substantive electricity changes are already in store.

The UCP has promised to end “costly subsidies” to renewable energy developments and abandon the NDP’s pledge to have such energy sources make up 30 per cent of all power generation by 2030.

It will remove the planned phase-out of coal-fired electricity generation, although federal regulations for a 2030 prohibition remain in place.

It will also ask the auditor general to conduct a special audit of the massive losses sustained by the province’s Balancing Pool due to power purchase arrangements being handed back to the agency three years ago.

While Kenney has pledged to cancel the provincewide carbon tax, a levy on large industrial greenhouse gas emitters (such has power plants) will still be charged, although at a reduced rate of $20 a tonne.

The biggest unknown remains the power market’s structure, which underpins how the entire system operates.

The UCP has promised to consult on the shift to the capacity market and report back to Albertans within 90 days.

The complex issue may sound like an eye-glazer, but it will have a profound effect on industry investment, as well as how much consumers pay on their monthly electricity bills.

A number of industry players worry the capacity market will lead AESO to procure more power than is necessary, foisting unnecessary costs onto all Albertans.

“I still have concerns for what the impact on consumers is going to be,” said energy market consultant Sheldon Fulton. “I’d love to see the capacity market go away.”

An analysis by EDC Associates found the transition to a capacity market will procure additional electricity before it’s needed, requiring consumers to pay up to 40 per cent more — an extra $1.4 billion — for power in 2021-22 than under the existing market structure.

“I don’t think there’s any prejudged outcome,” said Blake Shaffer, former head trader at TransAlta Corp. and a fellow-in-residence at the C.D. Howe Institute.

“But it really matters about getting this right.”

Evan Bahry, executive director of the Independent Power Producers Society of Alberta, said the fact the UCP’s review was confined to just 90 days is helpful, as it avoids throwing the entire industry into a prolonged period of uncertainty.

As for the greening of Alberta’s power grid, amid growing attention to clean grids and storage, the demise of the NDP’s Renewable Electricity Program will likely slow down the rapid pace of wind and solar development. But it’s unlikely to stop the growth trend as costs continue to fall for such developments.

“Renewables over the last number of years have evolved to the point that they make sense on a subsidy-free basis,” said Dan Balaban, CEO of Greengate Power Corp., which has developed 480 MW of wind power in Alberta and Ontario.

“There is a path to clean electricity ahead.”

London Underground Power Outage 2025 disrupted Tube lines citywide, with a National Grid voltage dip causing service suspensions, delays, and station closures; TfL recovery efforts spotlight infrastructure resilience, contingency planning, and commuter safety communications.

Key Points

A citywide Tube disruption on May 12, 2025, triggered by a National Grid voltage dip, exposing resilience gaps.

✅ Bakerloo, Waterloo & City, Northern suspended; Jubilee disrupted.

✅ Cause: brief National Grid fault leading to a voltage dip.

✅ TfL focuses on recovery, communication, and resilience upgrades.

On May 12, 2025, a significant power outage disrupted the London Underground during the afternoon rush hour, affecting thousands of commuters across the city. The incident highlighted vulnerabilities in the city's transport infrastructure, echoing a morning outage in London reported earlier, and raised concerns about the resilience of urban utilities.

The Outage and Its Immediate Impact

The power failure occurred around 2:30 PM, leading to widespread service suspensions and delays on several key Tube lines. The Bakerloo and Waterloo & City lines were completely halted, while the Jubilee line experienced disruptions between London Bridge and Finchley Road. The Northern line was also suspended between Euston and Kennington, as well as south of Stockwell. Additionally, Elizabeth Line services between Abbey Wood and Paddington were suspended. Some stations were closed for safety reasons due to the lack of power.

Commuters faced severe delays, with many stranded in tunnels or on platforms. The lack of information and communication added to the confusion, as passengers were left uncertain about the cause and duration of the disruptions.

Cause of the Power Failure

Transport for London (TfL) attributed the outage to a brief fault in the National Grid's transmission network. Although the fault was resolved within seconds, it caused a voltage dip that affected local distribution networks, leading to the power loss in the Underground system.

The incident underscored the fragility of the city's transport infrastructure, particularly the aging electrical and signaling systems that are vulnerable to such faults, as well as weather-driven events like a major windstorm outage that can trigger cascading failures. While backup systems exist, their capacity to handle sudden disruptions remains a concern.

Broader Implications for Urban Infrastructure

This power outage is part of a broader pattern of infrastructure challenges facing London. In March 2025, a fire at an electrical substation in Hayes led to the closure of Heathrow Airport, affecting over 200,000 passengers, while similar disruptions at BWI Airport have underscored aviation vulnerabilities. These incidents have prompted discussions about the resilience of the UK's energy and transport networks.

Experts argue that aging infrastructure, coupled with increasing demand and climate-related stresses, poses significant risks to urban operations, as seen in a North Seattle outage and in Toronto storm-related outages that tested local grids. There is a growing call for investment in modernization and diversification of energy sources to ensure reliability and sustainability.

TfL's Response and Recovery Efforts

Following the outage, TfL worked swiftly to restore services. By 11 PM, all but one line had resumed operations, with only the Elizabeth Line continuing to experience severe delays. TfL officials acknowledged the inconvenience caused to passengers and pledged to investigate the incident thoroughly, similar to the Atlanta airport blackout inquiry conducted after a major outage, to prevent future occurrences.

In the aftermath, TfL emphasized the importance of clear communication with passengers during disruptions and committed to enhancing its contingency planning and infrastructure resilience.

Public Reaction and Ongoing Concerns

The power outage sparked frustration among commuters, many of whom took to social media to express their dissatisfaction, echoing sentiments during Houston's extended outage about communication gaps and delays. Some passengers reported being trapped in tunnels for extended periods without clear guidance from staff.

The incident has reignited debates about the adequacy of London's transport infrastructure and the need for comprehensive upgrades. While TfL has initiated reviews and improvement plans, the public remains concerned about the potential for future disruptions and the city's preparedness to handle them.

The May 12 power outage serves as a stark reminder of the vulnerabilities inherent in urban infrastructure. As London continues to grow and modernize, ensuring the resilience of its transport and energy networks will be crucial. This includes investing in modern technologies, enhancing communication systems, and developing robust contingency plans to mitigate the impact of future disruptions. For now, Londoners are left reflecting on the lessons learned from this incident and hoping for a more reliable and resilient transport system in the future.

Nova Scotia Biomass Energy faces scrutiny as hydropower from Muskrat Falls via the Maritime Link increases, raising concerns over carbon emissions, biodiversity, ratepayer costs, and efficiency versus district heating in the province's renewable mix.

Key Points

Electricity from wood chips and waste wood in Nova Scotia, increasingly questioned as hydropower from the Maritime Link grows.

✅ Hydropower deliveries reduce need for biomass on the grid

✅ Biomass is inefficient, costly, and impacts biodiversity

✅ District heating offers better use of forestry residuals

The Ecology Action Centre's senior wilderness coordinator is calling on the Nova Scotia government to reduce the use of biomass to generate electricity now that more hydroelectric power is flowing into the province.

In 2020, the government of the day signed a directive for Nova Scotia Power to increase its use of biomass to generate electricity, including burning more wood chips, waste wood and other residuals from the forest industry. At the time, power from Muskrat Falls hydroelectric project in Labrador was not flowing into the province at high enough levels to reach provincial targets for electricity generated by renewable resources.

In recent months, however, the Maritime Link from Muskrat Falls has delivered Nova Scotia's full share of electricity, and, in some cases, even more, as the province also pursues Bay of Fundy tides projects to diversify supply.

Ray Plourde with the Ecology Action Centre said that should be enough to end the 2020 directive.

Ray Plourde is senior wilderness coordinator for the Ecology Action Centre. (CBC)
Biomass is "bad on a whole lot of levels," said Plourde, including its affects on biodiversity and the release of carbon into the atmosphere, he said. The province's reliance on waste wood as a source of fuel for electricity should be curbed, said Plourde.

"It's highly inefficient," he said. "It's the most expensive electricity on the power grid for ratepayers."

A spokesperson for the provincial Natural Resources and Renewables Department said that although the Maritime Link has "at times" delivered adequate electricity to Nova Scotia, "it hasn't done so consistently," a context that has led some to propose an independent planning body for long-term decisions.

"These delays and high fossil fuel prices mean that biomass remains a small but important component of our renewable energy mix," Patricia Jreiga said in an email, even as the province plans to increase wind and solar projects in the years ahead.

But to Plourde, that explanation doesn't wash.

The Nova Scotia Utility and Review Board recently ruled that Nova Scotia Power could begin recouping costs of the Maritime Link project from ratepayers. As for the rising cost of fossil fuels, Ploude noted that the inefficiency of biomass means there's no deal to be had using it as a fuel source.

"Honestly, that sounds like a lot of obfuscation," he said of the government's position.

No update on district heating plans
At the time of the directive, government officials said the increased use of forestry byproducts at biomass plants in Point Tupper and Brooklyn, N.S., including the nearby Port Hawkesbury Paper mill, would provide a market for businesses struggling to replace the loss of Northern Pulp as a customer. Brooklyn Power has been offline since a windstorm damaged that plant in February, however. Repairs are expected to be complete by the end of the year or early 2023.

Ploude said a better use for waste wood products would be small-scale district heating projects, while others advocate using more electricity for heat in cold regions.

Although the former Liberal government announced six public buildings to serve as pilot sites for district heating in 2020, and a list of 100 other possible buildings that could be converted to wood heat, there have been no updates.

"Currently, we're working with several other departments to complete technical assessments for additional sites and looking at opportunities for district heating, but no decisions have been made yet," provincial spokesperson Steven Stewart said in an email.
