Rosendin begins work on stadium retrofit

Rolls-Royce and Exelon UKSMR Partnership accelerates factory-built small modular reactors, nuclear power, clean energy, 440MW units, advanced manufacturing, fleet deployment, net zero goals, and resilient, low-cost baseload generation in the UK and globally.

Key Points

A partnership to deploy factory-built SMR stations, providing 440MW low-carbon baseload for the UK and export markets.

✅ 440MW factory-built SMR units with rapid modular assembly

✅ Exelon to operate and enhance high capacity factors

✅ Supports UK net zero, jobs, and export-led manufacturing

Rolls-Royce and Exelon Generation have signed a Memorandum of Understanding to pursue the potential for Exelon Generation to operate compact nuclear power stations both in the UK and internationally, including markets such as Canada where New Brunswick SMR questions are prompting public debate today.

Exelon Generation will be using their operational experience to assist Rolls Royce in the development and deployment of the UKSMR.

Rolls-Royce is leading a consortium that is designing a low-cost factory built nuclear power station, known as a small modular reactor (SMR), with UK mini-reactor approval anticipated as development progresses. Its standardised, factory-made components and advanced manufacturing processes push costs down, while the rapid assembly of the modules and components inside a weatherproof canopy on the power station site itself avoid costly schedule disruptions.

The consortium is working with its partners and UK Government to secure a commitment for a fleet of factory built nuclear power stations, each providing 440MW of electricity, to be operational within a decade, helping the UK meet its net zero obligations in line with the green industrial revolution policy set out by government. A fleet deployment in the UK will lead to the creation of new factories that will make the components and modules which will help the economy recover from the Covid-19 pandemic and pave the way for significant export opportunities as well.

The consortium members feature the best of nuclear engineering, construction and infrastructure expertise in Assystem, Atkins, BAM Nuttall, Jacobs, Laing O'Rourke, National Nuclear Laboratory, Nuclear Advanced Manufacturing Research Centre, Rolls-Royce and TWI. Exelon will add valuable operational experience to the team.

Tom Samson, interim Chief Executive Officer of the UKSMR consortium, said: 'Nuclear power is central to tackling climate change and economic recovery, but it must be affordable, reliable and investable and the way we manufacture and assemble our power station brings its cost down to be comparable with offshore wind.

'It's a compelling proposition that could draw new players into the UK's power generation landscape, improving choice for consumers and providing uninterrupted low carbon energy to homes and businesses.

'The opportunity to partner with Exelon is a very exciting prospect for our program, complementing our existing Consortium partnerships with one of the world's largest nuclear operator adds an important dimension to our growth ambitions, embodies the strength of the UK and USA alliance on nuclear matters and reflects wider international moves, such as a Canadian premiers' SMR initiative to accelerate technology development, and offers our future customers the ability to achieve the highest performance standards associated with Exelon's outstanding operational track record.'

The power stations will be built by the UKSMR consortium, before being handed over to be operated by power generation companies. Exelon Generation will work closely with the consortium during the pre-operation period. Exelon Nuclear operates 21 nuclear reactors in America, and U.S. regulators recently issued a final safety evaluation for a NuScale SMR that underscores momentum in the sector. The Exelon nuclear fleet is an integral part of the U.S. clean power mix; it produces more than 158 million megawatt-hours of clean electricity every year.

Bryan Hanson, EVP and COO of Exelon Generation said: 'We believe that SMRs are a crucial part of the world's clean energy mix, as projects like Darlington SMRs advance in Ontario. With our experience both in the US and internationally, Exelon is confident that we can help Rolls Royce ensure SMRs play a key role in the UK's energy future. We've had a very strong record of performance for 20 consecutive years, with a 2019 capacity factor of 95.7 percent. We will leverage this experience to achieve sustainably high capacity factors for the UKSMRs.'

Ralph Hunter, Managing Director of Exelon Nuclear Partners, who runs Exelon's international clean energy business, said: 'We have a strong track record of success to be the operator of choice for the UKSMR. We will help develop operational capability, training and human capacity development in the UK, as utilities such as Ontario Power Generation commit to SMRs abroad, ensuring localisation of skills and a strong culture of safety, performance and efficiency.'

By 2050 a full UK programme of a fleet of factory built nuclear power stations in the UK could create:

Up to 40,000 jobs GBP52BN of value to the UK economy GBP250BN of exports

The current phase of the programme has been jointly funded by all consortium members and UK Research and Innovation.

EV Flood Fire Risks highlight climate change impacts, lithium-ion battery hazards, water damage, post-submersion inspection, first responder precautions, manufacturer safeguards, and insurance considerations for extreme weather, flood-prone areas, and hurricane aftermaths.

Key Points

Water-exposed EV lithium-ion batteries may ignite later, requiring inspection, isolation, and trained responders.

✅ Avoid driving through floodwaters; park on high ground.

✅ After submersion, isolate vehicle; seek qualified inspection.

✅ Inform first responders and insurers about EV water damage.

As climate change intensifies the frequency and severity of extreme weather events, concerns about electric vehicle (EV) safety in flood-prone areas have come to the forefront. Recent warnings from officials regarding the risks of electric vehicles catching fire due to flooding from Hurricane Idalia underscore the need for heightened awareness and preparedness among consumers and emergency responders, as well as attention to grid reliability during disasters.

The alarming incidents of EVs igniting after being submerged in floodwaters have raised critical questions about the safety of these vehicles during severe weather conditions. While electric vehicles are often touted for their environmental benefits and lower emissions, it is crucial to understand the potential risks associated with their battery systems when exposed to water, even as many drivers weigh whether to buy an electric car for daily use.

The Risks of Submerging Electric Vehicles

Electric vehicles primarily rely on lithium-ion batteries, which can be sensitive to water exposure. When these batteries are submerged, they risk short-circuiting, which may lead to fires. Unlike traditional gasoline vehicles, where fuel may leak out, the sealed nature of an EV’s battery can create hazardous situations when compromised. Experts warn that even after water exposure, the risk of fire can persist, sometimes occurring days or weeks later.

Officials emphasize the importance of vigilance in flood-prone areas, including planning for contingencies like mobile charging and energy storage that support recovery. If an electric vehicle has been submerged, it is crucial to have it inspected by a qualified technician before attempting to drive it again. Ignoring this can lead to catastrophic consequences not only for the vehicle owner but also for surrounding individuals and properties.

Official Warnings and Recommendations

In light of these dangers, safety officials have issued guidelines for electric vehicle owners in flood-prone areas. Key recommendations include:

1. Avoid Driving in Flooded Areas: The most straightforward advice is to refrain from driving through flooded streets, which can not only damage the vehicle but also pose risks to personal safety.

2. Inspection After Flooding: If an EV has been submerged, owners should seek immediate professional inspection. Technicians can evaluate the battery and electrical systems for damage and determine if the vehicle is safe to operate.

3. Inform Emergency Responders: In flood situations, informing emergency personnel about the presence of electric vehicles can help them mitigate risks during rescue operations, including firefighter health risks that may arise. First responders are trained to handle conventional vehicles but may need additional precautions when dealing with EVs.

Industry Response and Innovations

In response to rising concerns, electric vehicle manufacturers are working to enhance the safety features of their vehicles. This includes developing waterproof battery enclosures and improving drainage systems to prevent water intrusion, as well as exploring vehicle-to-home power for resilience during outages. Some manufacturers are also investing in research to improve battery chemistry, making them more resilient in extreme conditions.

The automotive industry recognizes that consumer education is equally important, particularly around utility impacts from mass-market EVs that affect planning. Manufacturers and safety organizations are encouraged to disseminate information about proper EV maintenance, the importance of inspections after flooding, and safety protocols for both owners and first responders.

The Role of Insurance Companies

As the risks associated with electric vehicle flooding become more apparent, insurance companies are also reassessing their policies. With increasing incidences of extreme weather, insurers are likely to adapt coverage options related to water damage and fire risks specific to electric vehicles. Policyholders should consult with their insurance providers to ensure they understand their coverage in the event of flooding.

Preparing for the Future

With the increasing adoption of electric vehicles, it is vital to prepare for the challenges posed by climate change and evolving state power grids capacity. Community awareness campaigns can play a significant role in educating residents about the risks and safety measures associated with electric vehicles during flooding events. By fostering a well-informed public, the likelihood of accidents and emergencies can be reduced.

Nova Scotia Power Rate Increase 2023-2024 approved by the UARB lifts electricity rates 14 percent, citing fuel costs and investments, despite Bill 212; includes ROE 9 percent, decarbonization deferral, and a storm cost recovery rider.

Key Points

An approved UARB rate case raising electricity bills about 14% over 2023-2024, with ROE 9% and cost recovery tools.

✅ UARB approves average 6.9% annual increases for 2023 and 2024.

✅ Maintains 9% ROE; sets storm cost rider trial and decarbonization deferral.

✅ Government opposed via Bill 212, but settlement mostly upheld.

Nova Scotia regulators approved a 14 per cent electricity rate hike on Thursday, defying calls by Premier Tim Houston to reject the increase.

Rates will rise on average by 6.9 per cent each year in 2023 and 2024.

In Newfoundland and Labrador, the NL Consumer Advocate called an 18 per cent electricity rate hike unacceptable amid affordability concerns.

The Nova Scotia Utility and Review Board (UARB) issued a 203-page decision ratifying most of the elements in a settlement agreement reached between Nova Scotia Power and customer groups after Houston's government legislated a rate, spending and profit cap on the utility in November.

The board said approval was in the public interest and the increase is "reasonable and appropriate."

"The board cannot simply disallow N.S. Power's reasonable costs to make rates more affordable. These principles ensure fair rates and the financial health of a utility so it can continue to invest in the system providing services to its customers," the three-member panel wrote.

"While the board can (and has) disallowed costs found to be imprudent or unreasonable, absent such a finding, N.S. Power's costs must be reflected in the rates."

In addition to the 14 per cent hike, the board maintained Nova Scotia Power's current return on equity of 9 per cent, with an earnings band of 8.75 to 9.25 per cent. It agreed in principle to establish a decarbonization deferral account to pay for the retirement of coal plants and related decommissioning costs, and implemented a storm cost recovery rider for a three-year trial period.

The board rejected several items in the agreement, including rolling some Maritime Link transmission capital projects into consumers' rates.

Nova Scotia Power welcomed the ruling in a statement, describing it as "the culmination of an extensive and transparent regulatory process over the past year."

Natural Resources and Renewables Minister Tory Rushton, who has said the government cannot order lower power rates in Nova Scotia, stated the UARB decision was not what the government wanted, but he did not indicate the government has any plans to bring forward legislation to overturn it. 

"We're disappointed by the decision today. We've always been very clear that we were standing by ratepayers right from the get-go but we also respect the independent body of the UARB and their decision today."

Pressure from the province
Houston claimed the settlement breached his government's legislation, known as Bill 212 in Nova Scotia, which he said was intended to protect ratepayers. It capped rates to cover non-fuel costs by 1.8 per cent. It did not cap rates to cover fuel costs or energy efficiency programs.

Bill 212 was passed after the board concluded weeks of public hearings into Nova Scotia Power's request for an electricity rate increase, its first general rate application in 10 years. Nova Scotia Power is a subsidiary of Halifax-based Emera, which is a publicly traded company.

The legislation triggered credit downgrades from two credit rating agencies who said it compromised the independence of the Nova Scotia Utility and Review Board.

In Newfoundland and Labrador, electricity users have begun paying for Muskrat Falls as project costs flow through rates, highlighting broader pressures on Atlantic Canada utilities.

In its decision, the board accepted that legislation was intended to protect ratepayers but did not preclude increases in rates.

"Given the exclusion of fuel and purchased power costs when these were expected to cause significant upward pressure on rates, it also did not preclude large increases in rates. Instead, the protection afforded by the Public Utilities Act amendments appears to be focused on N.S. Power's non-fuel costs, with several amendments targeting N.S. Power's cost of capital and earnings."

The board noted the province was the only intervenor in the rate case to object to the settlement.

Opposition reaction
Rushton said despite the outcome, Bill 212 achieved its goal, which was to protect ratepayers.

"Without Bill 212 the rates would have actually been higher," he said. "It would have double-digit rates for this year and next year and now it's single digits."

NDP Leader Claudia Chender said the end result is that Nova Scotians are still facing "incredibly unaffordable power."

Similar criticism emerged in Saskatchewan after an 8 per cent SaskPower increase, which the NDP opposed during provincial debates.

"It's really unfortunate for a lot of Nova Scotians who are heading into a freezing weekend where heat is not optional."

Chender said a different legislative approach is needed to change the regulatory system, and more needs to be done to help people pay their electricity bills.

Liberal MLA Kelly Regan echoed that sentiment.

"There are lots of people who can absorb this. There are a lot of people who cannot, and those are the people that we should be worried about right now. This is why we've been saying all along the government needs to actually give money directly to Nova Scotians who need help with power rates."

Rushton said the government has introduced programs to help Nova Scotians pay for heat, including raising the income threshold to access the Heating Assistance Rebate Program and creating incentives to install heat pumps.

Elsewhere, some governments have provided a lump-sum credit on electricity bills to ease short-term costs for households.

Coinmint Plattsburgh Dispute spotlights cryptocurrency mining, hydropower electricity rates, a $1M security deposit, Public Service Commission rulings, municipal utility policies, and seasonal migration to Massena data centers as Bitcoin price volatility pressures operations.

Key Points

Legal and energy-cost dispute over crypto mining, a $1,019,503 deposit, and operations in Plattsburgh and Massena.

✅ PSC allows higher rates and requires large security deposits.

✅ Winter electricity spikes drove a $1M deposit calculation.

✅ Coinmint shifted capacity to Massena data centers.

A few years ago, there was a lot of buzz about the North Country becoming the next Silicon Valley of cryptocurrency, even as Maine debated a 145-mile line that could reshape regional power flows. One of the companies to flock here was Coinmint. The cryptomining company set up shop in Plattsburgh in 2017 and declared its intentions to be a good citizen.

Today, Coinmint is fighting a legal battle to avoid paying the city’s electric utility more than $1 million owed for a security deposit. In addition to that dispute, a local property manager says the firm was evicted from one of its Plattsburgh locations.

Companies like Coinmint chose to come to the North Country because of the relatively low electricity prices here, thanks in large part to the hydropower dam on the St. Lawrence River in Massena, and regionally, projects such as the disputed electricity corridor have drawn attention to transmission costs and access. Coinmint operates its North Country Data Center facilities in Plattsburgh and Massena. In both locations, racks of computer servers perform complex calculations to generate cryptocurrency, such as bitcoin.

When cryptomining began to take off in Plattsburgh, the cost of one bitcoin was skyrocketing. That brought hype around the possibility of big business and job creation in the North Country. But cryptomininers like Coinmint were using massive amounts of energy in the winter of 2017-2018, and that season, electric bills of everyday Plattsburgh residents spiked.

Many cryptomining firms operate in a state of flux, beholden to the price of Bitcoin and other cryptocurrencies, even as the end to the 'war on coal' declaration did little to change utilities' choices. When the price of one bitcoin hit $20,000 in 2017, it fell by 30% just days later. That’s one reason why the price of electricity is so critical for companies like Coinmint to turn a profit. 

Plattsburgh puts the brakes on “cryptocurrency mining”
In early 2018, Plattsburgh passed a moratorium on cryptocurrency mining operations, after residents complained of higher-than-usual electric bills.

“Your electric bill’s $100, then it’s at $130. Why? It’s because these guys that are mining the bitcoins are riding into town, taking advantage of a situation,” said resident Andrew Golt during a 2018 public hearing.

Coinmint aimed to assuage the worries of residents and other businesses. “At the end of the day we want to be a good citizen in whatever communities we’re in,” Coinmint spokesman Kyle Carlton told NCPR at that 2018 meeting.

“We’re open to working with those communities to figure out whatever solutions are going to work.”

The ban was lifted in Feb. 2019. However, since it didn’t apply to companies that were already mining cryptocurrency in Plattsburgh, Coinmint has operated in the city all along.

Coinmint challenges attempt to protect ratepayers
New rules passed by the New York Public Service Commission in March 2018 allow municipal power authorities including Plattsburgh’s to charge big energy users such as Coinmint higher electricity rates, amid customer backlash in other utility deals. The new rules also require them to put down a security deposit to ensure their bills get paid.

But Coinmint disputes that deposit charge. The company has been embroiled in a legal fight for nearly a year against Plattsburgh Municipal Lighting Department (PMLD) in an attempt to avoid paying the electric utility’s security deposit bill of $1,019,503. That bill is based on an estimate of what would cover two months of electricity use if a company were to leave town without paying its electric bills.

Coinmint would not discuss the dispute on the record with NCPR. Legal documents show the firm argues the deposit charge is inflated, based on a flawed calculation resulting in a charge hundreds of thousands of dollars higher than what it should be.

“Essentially they’re arguing that they should only have to put up some average of their monthly bills without accounting for the fact that winter bills are significantly higher than the average,” said Ken Podolny, an attorney representing the Plattsburgh utility.

The company took legal action in February 2019 against PMLD in the hopes New York’s energy regulator, the Public Service Commission, would agree with Coinmint that the deposit charge was too high. An informal commission hearing officer disagreed, and ruled in October the charge was calculated correctly.

Coinmint appealed the ruling in November and a hearing on the appeal could come as soon as February.

Less than a week after Coinmint lost its initial challenge of the deposit charge, the company made a splashy announcement trumpeting its plans to “migrate its Plattsburgh, New York infrastructure to its Massena, New York location for the 2019-2020 winter season.”

The announcement made no mention of the appeal or the recent ruling against Coinmint. The company attributed its new plan to “exceptionally-high” electricity rates in Plattsburgh, as hydropower transmission projects elsewhere in New England faced their own controversies. 

"We recognize some in the Plattsburgh community have blamed our operation for pushing rates higher for everyone so, while we disagree with that assessment, we hope this seasonal migration will have a positive impact on rates for all our neighbors,” said Coinmint cofounder Prieur Leary in the press statement.

“In the event that doesn't happen, we trust the community will look for the real answers for these high costs." Prieur Leary has since been removed from the corporate team page on the company’s website.

The company still operates in Plattsburgh at one of its locations in the city. As for staff, while at least two Coinmint employees have moved from Plattsburgh to Massena, where the company operates a data center inside a former Alcoa aluminum plant, it is unclear how many people in total have made the move.

Coinmint left its second Plattsburgh location in 2019. The company would not discuss that move on the record, yet the circumstances of the departure are murky.

The local property manager of the industrial park site told NCPR, “I have no comment on our evicted tenant Coinmint.” The property owner, California’s Karex Property Management Services, also would not comment regarding the situation, noting that “all staff have been told to not discuss anything regarding our past tenant Coinmint.”

Today, Bitcoin and other cryptocurrencies are worth a fraction of what they were back in 2017 when Coinmint came to the North Country, and now, amid a debate over Bitcoin's electricity use shaping market sentiment, the future of the entire industry here remains uncertain.

Germany EV Subsidy Cut triggers budget-crisis fallout in the automotive industry, after a constitutional court ruling; EV incentives end, threatening electromobility adoption, manufacturer competitiveness, 2030 targets, and demand amid Chinese competition and weak global growth.

Key Points

A sudden end to Germany's EV incentives due to a budget shortfall after a court ruling, hurting automakers and adoption.

✅ Ends buyer rebates amid budget crisis ruling

✅ Risks 2030 EV targets and industry competitiveness

✅ Weak demand and China competition intensify

The German government has faced a backlash after abruptly ending an electric car subsidy scheme in a blow to the already struggling automotive industry.

The scheme is one of the casualties of a budget crisis caused by a shock constitutional court ruling in November that upended the government's spending plans.

The economy ministry said Saturday that Sunday would be the last day prospective buyers could apply for the scheme, which paid out thousands of euros per customer to partially cover the cost of buying an electric car today.

A spokesman for the ministry admitted it was an "unfortunate situation" for consumers who had been hoping to take advantage of the subsidy, but it had no choice "because there is no longer enough money available."

Analyst Ferdinand Dudenhoeffer from the Center for Automotive Research warned the decision could have dramatic consequences amid a Europe EV slump already pressuring demand.

"The competitiveness of [auto] manufacturers will now be severely damaged," Dudenhoeffer told the Rheinische Post newspaper.

The Handelsblatt business daily had already warned that scrapping the scheme risked jeopardizing Germany's plans to get 15 million electric cars on the road by 2030, even though the EU EV share grew during lockdowns earlier in the pandemic.

"This goal was already considered extremely unrealistic. Now it seems completely illusory," it wrote.

In the UK, analysts warn that electric cars could cost more if a post-Brexit deal is not reached, underscoring wider market uncertainties.

A total of around 10 billion euros ($1.1 billion) has been paid out since 2016 under the scheme for around 2.1 million electric vehicles, according to the economy ministry.

Germany's flagship automotive industry, including Volkswagen, has been struggling with the transition to electromobility due to a weak global economy and low levels of demand.

In addition, it is facing a serious challenge from homegrown rivals in China, one of its most important markets, as France moves to discourage Chinese EVs with new rules.

"The Chinese are massively expanding their car industry because they have customers. Our manufacturers no longer have any," Dudenhoeffer said, as France's incentive rules make the market tougher for Chinese brands.

Germany's highest court decided last month that the government had broken a constitutional debt rule when it transferred 60 billion euros earmarked for pandemic support to a climate fund.

The bombshell ruling blew a huge hole in spending plans and plunged Chancellor Olaf Scholz's three-way coalition into turmoil.

After adopting an emergency budget for 2023, Scholz and his junior coalition partners battled for weeks before finally finding an agreement for 2024.

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.
