New breed of renewable players emerging

Energy Vault Gravity Storage uses crane-stacked concrete blocks to deliver long-duration, grid-scale renewable energy; a SoftBank Vision Fund-backed, pumped-hydro analog enabling baseload power and a lithium-ion alternative with proprietary control algorithms.

Key Points

Gravity-based cranes stack blocks to store and dispatch power for hours, enabling grid-scale, low-cost storage.

✅ 4 MW/35 MWh modules; ~9-hour duration

✅ Estimated $200-$250/kWh; lower LCOE than lithium-ion

✅ Backed by SoftBank Vision Fund; Cemex and Tata support

Energy Vault, the Swiss-U.S. startup that says it can store and discharge electrical energy through a super-sized concrete-and-steel version of a child’s erector set, has landed a $110 million investment from Japan’s SoftBank Vision Fund to take its technology to commercial scale.

Energy Vault, a spinout of Pasadena-based incubator Idealab and co-founded by Idealab CEO and billionaire investor Bill Gross, unstealthed in November with its novel approach to using gravity to store energy.

Simply put, Energy Vault plans to build storage plants — dubbed “Evies” — consisting of a 35-story crane with six arms, surrounded by a tower consisting of thousands of concrete bricks, each weighing about 35 tons.

This plant will “store” energy by using electricity to run the cranes that lift bricks from the ground and stack them atop of the tower, and “discharge” energy by reversing that process. It’s a mechanical twist on the world’s most common energy storage technology, pumped hydro, which “stores” energy by pumping water uphill, and lets it fall to spin turbines when electricity is needed, even as California funds 100-hour long-duration storage pilots to expand flexibility worldwide.

But behind this simplicity lies some heavy-duty software to orchestrate the cranes and blocks, with a "unique stack of proprietary algorithms" to balance energy supply and demand, volatility, grid stability, weather elements and other variables.

CEO and co-founder Robert Piconi said in a November interview with GTM that the standard array would deliver 4 megawatts/35 megawatt-hours of storage, which translates to nearly 9 hours of duration — the equivalent of building the tower to its height, and then reducing it to ground level. It can be built on-site in partnership with crane manufacturers and recycled concrete material, and can run fully automated for decades with little deterioration, he said.

And the cost, which Piconi pegged in the $200 to $250 per kilowatt-hour range, with room to decline further, is roughly 50 percent below the upfront price of the conventional storage market today, and 80 percent below it on levelized cost, he said, a trend utilities see benefits in as they plan resources.

The result, according to Wednesday’s statement, is a technology that could allow “renewables to deliver baseload power for less than the cost of fossil fuels 24 hours a day,” in applications such as community microgrids serving low-income housing.

Wednesday’s announcement builds on a recent investment from Mexico's Cemex Ventures, the corporate venture capital unit of building materials giant Cemex, along with a promise of deployment support from Cemex's strategic network, and also follows project financing for a California green hydrogen microgrid led by the company. Piconi said in November that the company had sufficient investment from two funding rounds to carry it through initial customer deployments, though he declined to disclose figures.

This is the first energy storage investment for Vision Fund, the $100 billion venture fund set up by SoftBank founder Masayoshi Son. While large by startup standards, it’s in keeping with the capital costs that Energy Vault will face in scaling up its technology to meet its commitments, amid mounting demand in regions like Ontario energy storage that face supply crunches. Those include a 35 megawatt-hour order with Tata Power Company, the energy-producing arm of the Indian industrial conglomerate, first unveiled in November, as well as plans to demonstrate its first storage tower in northern Italy in 2019.

For Vision Fund, it’s also an unusual choice for a storage investment, given that the vast majority of venture capital in the industry today is being directed toward lithium-ion batteries, and even Mercedes-Benz energy storage ventures targeting the U.S. market. Lithium-ion batteries are limited in terms of how many hours they can provide cost-effectively, with about 4 hours being seen as the limit today.

The search for long-duration energy storage has driven investment into flow battery technologies such as grid-scale vanadium systems deployed on utility networks, compressed-air energy storage and variations on gravity-based storage, including a previous startup backed by Gross and Idealab, Energy Cache, whose idea of using a ski lift carrying buckets of gravel up a hill to store energy petered out with a 50-kilowatt pilot project.

Ontario Electricity Bill Scams: beware phishing, spoofed calls, fake invoices, and disconnection threats demanding prepaid cards, gift cards, or Bitcoin; verify with Hydro One, Alectra, Toronto Hydro, Elexicon, or Hydro Ottawa customer service.

Key Points

Fraud schemes impersonating utilities via calls, texts, emails, or fake bills to coerce instant payment with threats.

✅ Never pay by gift cards, prepaid debit, or Bitcoin.

✅ Do not call numbers in messages; use your bill or utility website.

✅ Verify IDs; report threats or door-to-door demands to police.

Ontario’s five largest electricity utilities have teamed up to warn the public about ongoing scams concerning fake phone calls, texts and bills connected to the utility accounts.

“We always receive these reports of scams and it gets increasingly higher during the holidays when people are busy and enjoying the season," said Whitney Brhelle, spokesperson with Hydro One.

Hydro One joined with Alectra Utilities, Elexicon Energy, Hydro Ottawa and Toronto Hydro to get the message out that scammers are targeting customers and threatening to turn off their power.

Scams involve impersonation of a local utility or its employees, threatening phone calls, texts or emails and pressure for immediate payment that come with threats to disconnect service the same day.

Criminals may demand payment in prepaid debit cards, gift cards or Bitcoin. Utilities said they would never call a customer without notice and threaten disconnection over the phone.

In a separate case, authorities in Montreal arrested suspects in an electricity theft ring that highlights broader energy-related crime.

“People have been calling customers and saying you need to pay your bill immediately and they are threatened with disconnection, often citing supposed changes to peak hydro rates to add pressure, which is something that we would ever do," said Kimberly Brathwaite, spokesperson with Elexicon Energy.

Scammers are also creating fake bills that look like the real thing.

“Scammers will actually take our Alectra logo and send out various authentic looking documents to people’s homes, so people have to be aware and check their statements very carefully” said Ashley Trgachef spokesperson with Alectra Utilities.

Customers are advised to never make a payment not listed on their recent bill and to ignore texts or emails with links promising refunds, and to verify any official relief fund information only through their utility and not to provide personal information or details about their account.

If you are given a number to call don’t call the number provided, you are better off to go to your bill or the utility’s website to makes sure it is the correct number for customer service and to review information about customer flexibility there.

Some scammers have even gone door to door demanding payment, and the utilities are advising anyone who feels threatened to call police.

They are also asking that you share the information with family and friends to be careful if they are contacted by someone claiming to be with their electricity company.

If you fall for a scam and money is sent, it's very difficult to get it back.

Nelson DC Fast-Charging EV Station delivers 50-kilowatt DCFC service at the community complex, expanding EV infrastructure in British Columbia with FortisBC, faster than Level 2 chargers, supporting clean transportation, range confidence, and highway corridor travel.

Key Points

A 50 kW public DC fast charger in Nelson, BC, run by FortisBC, providing rapid EV charging at the community complex.

✅ 50 kW DCFC cuts charge time to about 30 minutes

✅ $9 per half hour session; convenient downtown location

✅ Funded by NRCan, BC government, and FortisBC

FortisBC and the City of Nelson celebrated the opening of Nelson's first publicly available direct current fast-charging (DCFC) electric vehicle (EV) station on Friday.

"Adopting EV's is one of many ways for individuals to reduce carbon emissions," said Mayor John Dooley, City of Nelson. "We hope that the added convenience of this fast-charging station helps grow EV adoption among our community, and we appreciate the support from FortisBC, the province and the federal government."

The new station, located at the Nelson and District Community Complex, provides a convenient and faster charge option right in the heart of the commercial district and makes Nelson more accessible for both local and out-of-town EV drivers. The 50-kilowatt station is expected to bring a compact EV from zero to 80 per cent charged in about a half an hour, as compared to the four Level-2 charging stations located in downtown Nelson that require from three to four hours. The cost for a half hour charge at the new DC fast-charging station is $9 per half hour.

This fast-charging station was made possible through a partnership between FortisBC, the City of Nelson, Nelson Hydro, the Province of British Columbia and Natural Resources Canada. As part of the partnership, the City of Nelson is providing the location and FortisBC will own and manage the station.

This is the latest of 12 fast-charging stations FortisBC has built over the last year with support from municipalities and all levels of government, and adds to the five FortisBC-owned Kootenay stations that were opened as part of the accelerate Kootenays initiative in 2018.

All 12 stations were 50 per cent funded by Natural Resources Canada, 25 per cent by BC Ministry of Energy, Mines and Petroleum Resources and the remaining 25 per cent by FortisBC. The funding is provided by Natural Resources Canada's Electric Vehicle and Alternative Fuel Infrastructure Deployment Initiative, which aims to establish a coast-to-coast network of fast-chargers along the national highway system, natural gas refueling stations along key freight corridors and hydrogen refueling stations in major metropolitan areas. It is part of the Government of Canada's more than $180-billion Investing in Canada infrastructure plan. The Government of British Columbia is also contributing $300,000 towards the fast-chargers through its Clean Energy Vehicle Public Fast Charging Program.

This station brings the total DCFC chargers FortisBC owns and operates to 17 stations across 14 communities in the southern interior. FortisBC continues to look for opportunities to expand this network as part of its 30BY30 goal of reducing emissions from its customers by 30 per cent by 2030.

"Electric vehicles play a key role in building a cleaner future. We are pleased to work with partners like FortisBC and the City of Nelson to give Canadians greener options to drive where they need to go, " said The Honourable Seamus O'Regan, Canada's Minister of Natural Resources.

"Nelson's first public fast-charging EV station increases EV infrastructure in the city, making it easier than ever to make the switch to cleaner transportation. Along with a range of rebates and financial incentives available to EV drivers, it is now more convenient and affordable to go electric and this station is a welcome addition to our EV charging infrastructure," said Michelle Mungall, BC's Minister of Jobs, Economic Development and Competitiveness, and MLA for Nelson Creston.

"Building the necessary DC fast-charging infrastructure, such as the Lillooet fast-charging site in British Columbia, close to highways and local amenities where drivers need them most is a critical step in growing electric vehicle adoption. Collaborations like this are proving to be an effective way to achieve this, and I'd like to thank all the program partners for their commitment in opening this important station, " said Mark Warren, Director of Business Innovation, FortisBC.

Saskatchewan Solar Net Metering Program lets rooftop solar users offset at retail rate while earning 7.5 cents/kWh credits for excess energy; rebates are removed, SaskPower balances grid costs with a 100 kW cap.

Key Points

An updated SaskPower plan crediting rooftop solar at 7.5 cents/kWh, offsetting usage at retail rate, without rebates.

✅ Excess energy credited at 7.5 cents/kWh

✅ Offsets on-site use at retail electricity rates

✅ Up to 100 kW generation; no program capacity cap

Saskatchewan has unveiled a new program that credits electricity customers for generating their own solar power, but it won’t pay as much as an older program did or reimburse them with rebates for their costs to buy and install equipment.

The new net metering program takes effect Nov. 1, and customers will be able to use solar to offset their own power use at the retail rate, similar to UK households' right to sell power in comparable schemes, though program details differ.

But they will only get 7.5 cents per kilowatt hour credit on their bills for excess energy they put back into the grid, as seen in Duke Energy payment changes in other jurisdictions, rather than the 14 cents in the previous program.

Dustin Duncan, the minister responsible for Crown-owned SaskPower, says the utility had to consider the interests of people wanting to use rooftop solar and everyone else who doesn’t have or can’t afford the panels, who he says would have to make up for the lost revenue.

Duncan says the idea is to create a green energy option, with wind power gains highlighting broader competitiveness, while also avoiding passing on more of the cost of the system to people who just cannot afford solar panels of their own.

Customers with solar panels will be allowed to generate up to 100 kilowatts of power against their bills.

“It’s certainly my hope that this is going to provide sustainability for the industry, as illustrated by Alberta's renewable surge creating jobs, that they have a program that they can take forward to their potential customers, while at the same time ensuring that we’re not passing onto customers that don’t have solar panels more cost to upkeep the grid,” Duncan said Tuesday.

Saskatchewan NDP leader Ryan Meili said he believes eliminating the rebate and cutting the excess power credit will kill the province’s solar energy, a concern consistent with lagging solar demand in Canada in recent national reports, he said.

“(Duncan) essentially made it so that any homeowner who wants to put up panels would take up to twice as long to pay it back, which effectively prices everybody in the small part of the solar production industry — the homeowners, the farms, the small businesses, the small towns — out of the market,” Meili said.

The province’s old net metering program hit its 16 megawatt capacity ahead of schedule, forcing the program to shut down, while disputes like the Manitoba Hydro solar lawsuit have raised questions about program management elsewhere. It also had a rebate of 20 per cent of the cost of the system, but that rebate has been discontinued.

The new net metering program won’t have any limit on program capacity, or an end date.

According to Duncan, the old program would have had a net negative impact to SaskPower of about $54 million by 2025, but this program will be much less — between $4 million and $5 million.

Duncan said other provinces either have already or are in the process of moving away from rebates for solar equipment, including Nova Scotia's proposed solar charge and similar reforms, and away from the one-to-one credits for power generation.

MARVEL microreactor debuts at Idaho National Laboratory as a 100 kW, liquid-metal-cooled, zero-emissions generator powering a nuclear microgrid, integrating wind and solar for firm, clean energy in advanced nuclear applications research.

Key Points

A 100 kW, liquid-metal-cooled INL reactor powering a nuclear microgrid and showcasing zero-emissions clean energy.

✅ 100 kW liquid-metal-cooled microreactor at INL

✅ Powers first nuclear microgrid for applications testing

✅ Integrates with wind and solar for firm clean power

Inside the Transient Reactor Test Facility, a towering, windowless gray block surrounded by barbed wire, researchers are about to embark on a mission to solve one of humanity’s greatest problems with a tiny device.

Next year, they will begin construction on the MARVEL reactor. MARVEL stands for Microreactor Applications Research Validation and EvaLuation. It’s a first-of-a-kind nuclear power generator with a mini-reactor design that is cooled with liquid metal and produces 100 kilowatts of energy. By 2024, researchers expect MARVEL to be the zero-emissions engine of the world’s first nuclear microgrid at Idaho National Laboratory (INL).

“Micro” and “tiny,” of course, are relative. MARVEL stands 15 feet tall, weighs 2,000 pounds, and can fit in a semi-truck trailer. But it's minuscule compared to conventional nuclear power plants, which span acres, produces gigawatts of electricity to power whole states, and can take more than a decade to build.

For INL, where scientists have tested dozens of reactors over the decades across an area three-quarters the size of Rhode Island, it’s a radical reimagining of the technology. This advanced reactor design could help overcome the biggest obstacles to nuclear energy: safety, efficiency, scale, cost, and competition. MARVEL is an experiment to see how all these pieces could fit together in the real world.

“It’s an applications test reactor where we’re going to try to figure out how we extract heat and energy from a nuclear reactor and apply it — and combine it with wind, solar, and other energy sources,” said Yasir Arafat, head of the MARVEL program.

The project, however, comes at a time when nuclear power is getting pulled in wildly different directions, from phase-outs to new strategies like the UK’s green industrial revolution that shapes upcoming reactors.

Germany just shut down its last nuclear reactors. The U.S. just started up its first new reactor in 30 years, underscoring a shift. France, the country with the largest share of nuclear energy on its grid, saw its atomic power output decline to its lowest since 1988 last year. Around the world, there are currently 60 nuclear reactors under construction, with 22 in China alone.

But the world is hungrier than ever for energy. Overall electricity demand is growing: Global electricity needs will increase nearly 70 percent by 2050 compared to today’s consumption, according to the Energy Information Administration. At the same time, the constraints are getting tighter. Most countries worldwide, including the U.S., have committed to net-zero goals by the middle of the century, even as demand rises.

To meet this energy demand without worsening climate change, the U.S. Energy Department’s report on advanced nuclear energy released in March said, “the U.S. will need ~550–770 [gigawatts] of additional clean, firm capacity to reach net-zero; nuclear power is one of the few proven options that could deliver this at scale.”

The U.S. government is now renewing its bets on nuclear power to produce steady electricity without emitting greenhouse gases. The Bipartisan Infrastructure Law included $6 billion to keep existing nuclear power plants running. In addition, the Inflation Reduction Act, the U.S. government’s largest investment in countering climate change, includes several provisions to benefit atomic power, including tax credits for zero-emissions energy.

“It’s a game changer,” said John Wagner, director of INL.

The tech sector is jumping in, too, as atomic energy heats up across startups and investors. In 2021, venture capital firms poured $3.4 billion into nuclear energy startups. They’re also pouring money into even more far-out ideas, like nuclear fusion power. Public opinion has also started moving. An April Gallup poll found that 55 percent of Americans favour and 44 percent oppose using atomic energy, the highest levels of support in 10 years.

UK Clean Electricity Record as wind, solar, and biomass boost renewable energy output, slashing carbon emissions and wholesale power prices during lockdown, while lower demand challenges grid balancing and drives a drop to 153 g/kWh.

Key Points

A milestone where wind, solar and biomass lifted renewables, cutting carbon intensity to 153 g/kWh during lockdown.

✅ Carbon intensity averaged 153 g/kWh in Q2 2020.

✅ Renewables output rose 32% via wind, solar, biomass.

✅ Wholesale power prices slumped 42% amid lower demand.

U.K electricity has never been cleaner. As wind, solar and biomass plants produced more power than ever in the second quarter, with a new wind generation record set, carbon emissions fell by a third from a year earlier, according to Drax Electric Insight’s quarterly report. Power prices slumped 42 per cent as demand plunged during lockdown. Total renewable energy output jumped 32 per cent in the period, as wind became the main source of electricity at times.

“The past few months have given the country a glimpse into the future for our power system, with higher levels of renewable energy, as wind led the power mix, and lower demand making for a difficult balancing act,”said  Iain Staffell, from Imperial College London and lead author of the report.

The findings of the report point to the impact energy efficiency can have on reducing emissions, as coal's share fell to record lows across the electricity system. Millions of people furloughed or working from home and shuttered shops up and down the country resulted in daily electricity demand dropping about 10% and being about four gigawatts lower than expected in the three months through June.

Average carbon emissions fell to a new low of 153 grams per kWh of electricity consumed over the quarter, as coal-free generation records were extended, even though low-carbon generation stalled in 2019, according to the report.
