The United States Department of Energy has given final approval to a $400 million loan guarantee to Abound Solar to expand production of its thin-film photovoltaic modules, a market pioneered by First Solar, the company said.

Abound also announced that it had raised $110 million from investors that include Invus Group, Bohemian Companies, DCM, GLG Partners, Technology Partners, BP Alternative Energy and West Hill Investors.

With the $110 million, the company, based in Loveland, Colorado, has received a total of $260 million in funding since its founding in 2007 and plans to expand in Colorado and Indiana.

The half billion dollars in new debt and equity is a huge sum for a three-year-old start-up that will produce just 30 megawatts of solar modules this year.

By contrast, First Solar — the Tempe, Arizona global heavyweight that makes the same type of cadmium telluride cad tel photovoltaic panels that Abound does — has a manufacturing capacity of 1,430 megawatts.

And therein lies the reason for the enthusiasm for Abound: The start-up's strategy is to feed from the crumbs that fall off First Solar's table in a booming market that the leader cannot supply on its own.

"First Solar has been the only game in town," Tom Tiller, Abound's chief executive, said in an interview. "Customers today don't have an alternative to First Solar if they want cad tel," he added, using industry shorthand for cadmium telluride.

"The opportunity in the market is to be a second source of supply for cad tel panels," he said.

The big bets investors and taxpayers are making on Abound are that it will eventually be able to match First Solar's low cost of production and that First Solar will not be able to keep up with demand.

While cadmium telluride panels are less efficient at converting sunlight into electricity than conventional photovoltaic modules, they do not use expensive polysilicon and can be manufactured more cheaply.

That advantage led General Electric earlier this year to announce that it would develop cadmium telluride modules with PrimeStar Solar, an Arvada, Colorado, company in which GE holds a majority stake.

Cadmium telluride solar panels typically are used to build photovoltaic power plants for utilities or are deployed to generate electricity for large commercial facilities.

Abound will tap the federal loan guarantee to expand production at its Longmont, Colorado, plant and build a new 781,000-square-foot factory in Tipton, Indiana.

Tiller said the expansion of the Colorado facility will be completed in 2012 and raise its annual production to 200 megawatts. Work on the Indiana factory, which was built to make automobile transmissions for Chrysler but was abandoned before it could start production when the carmaker filed for bankruptcy, will begin in 2012 and will give Abound a total manufacturing capacity of 840 megawatts by 2014. The new plants will employ 1,200 people.

Doug Ford's New Stance on Wind Power in Ontario

Ontario Wind Power Policy Shift signals renewed investment in renewable energy, wind farms, and grid resilience, aligning with climate goals, lower electricity costs, job creation, and turbine technology for cleaner, diversified power.

 

Key Points

A provincial pivot to expand wind energy, meet climate goals, lower costs, and boost jobs across Ontario’s power system.

✅ Diversifies Ontario's grid with scalable renewable capacity.

✅ Targets emissions cuts while stabilizing electricity prices.

✅ Spurs rural investment, supply chains, and skilled jobs.

 

Ontario’s energy landscape is undergoing a significant transformation as Premier Doug Ford makes a notable shift in his approach to wind power. This change represents a strategic pivot in the province’s energy policy, potentially altering the future of Ontario’s power generation, environmental goals, and economic prospects.

The Backdrop: Ford’s Initial Stance on Wind Power

When Doug Ford first assumed the role of Premier in 2018, his administration was marked by a strong stance against renewable energy projects, including wind power, with Ford later saying he was proud of tearing up contracts as part of this shift. Ford’s government inherited a legacy of ambitious renewable energy commitments from the previous Liberal administration under Kathleen Wynne, which had invested heavily in wind and solar energy. The Ford government, however, was critical of these initiatives, arguing that they resulted in high energy costs and a surplus of power that was not always needed.

In 2019, Ford’s government began rolling back several renewable energy projects, including wind farms, and was soon tested by the Cornwall wind farm ruling that scrutinized a cancellation. This move was driven by a promise to reduce electricity bills and cut what was perceived as wasteful spending on green energy. The cancellation of several wind projects led to frustration among environmental advocates and the renewable energy sector, who viewed the decision as a setback for Ontario’s climate goals.

The Shift: Embracing Wind Power

Fast forward to 2024, and Premier Ford’s administration is taking a markedly different approach. The recent policy shift, which moves to reintroduce renewable projects, indicates a newfound openness to wind power, reflecting a broader acknowledgment of the changing dynamics in energy needs and environmental priorities.

Several factors appear to have influenced this shift:

  1. Rising Energy Demands and Climate Goals: Ontario’s growing energy demands, coupled with the pressing need to address climate change, have necessitated a reevaluation of the province’s energy strategy. As Canada commits to reducing greenhouse gas emissions and transitioning to cleaner energy sources, wind power is increasingly seen as a crucial component of this strategy. Ford’s change in direction aligns with these national and global goals.

  2. Economic Considerations: The economic landscape has also evolved since Ford’s initial opposition to wind power. The cost of wind energy has decreased significantly over the past few years, making it a more competitive and viable option compared to traditional energy sources, as competitive wind power gains momentum in markets worldwide. Additionally, the wind energy sector promises substantial job creation and economic benefits, which are appealing in the context of post-pandemic recovery and economic growth.

  3. Public Opinion and Pressure: Public opinion and advocacy groups have played a role in shaping policy. There has been a growing demand from Ontarians for more sustainable and environmentally friendly energy solutions. The Ford administration has been responsive to these concerns, recognizing the importance of addressing public and environmental pressures.

  4. Technological Advancements: Advances in wind turbine technology have improved efficiency and reduced the impact on wildlife and local communities. Modern wind farms are less intrusive and more effective, addressing some of the concerns that were previously associated with wind power.

Implications of the Policy Shift

The implications of Ford’s shift towards wind power are far-reaching. Here are some key areas affected by this change:

  1. Energy Portfolio Diversification: By reembracing wind power, Ontario will diversify its energy portfolio, reducing its reliance on fossil fuels and increasing the proportion of renewable energy in the mix. This shift will contribute to a more resilient and sustainable energy system.

  2. Environmental Impact: Increased investment in wind power will contribute to Ontario’s efforts to combat climate change. Wind energy is a clean, renewable source that produces no greenhouse gas emissions during operation. This aligns with broader environmental goals and helps mitigate the impact of climate change.

  3. Economic Growth and Job Creation: The wind power sector has the potential to drive significant economic growth and create jobs. Investments in wind farms and associated infrastructure can stimulate local economies, particularly in rural areas where many wind farms are located.

  4. Energy Prices: While the initial shift away from wind power was partly motivated by concerns about high energy costs, including exposure to costly cancellation fees in some cases, the decreasing cost of wind energy could help stabilize or even lower electricity prices in the long term. As wind power becomes a larger component of Ontario’s energy supply, it could contribute to a more stable and affordable energy market.

Moving Forward: Challenges and Opportunities

Despite the positive aspects of this policy shift, there are challenges to consider, and other provinces have faced setbacks such as the Alberta wind farm scrapped by TransAlta that illustrate potential hurdles. Integrating wind power into the existing grid requires careful planning and investment in grid infrastructure. Additionally, addressing local concerns about wind farms, such as their impact on landscapes and wildlife, will be crucial to gaining broader acceptance.

Overall, Doug Ford’s shift towards wind power represents a significant and strategic change in Ontario’s energy policy. It reflects a broader understanding of the evolving energy landscape and the need for a sustainable and economically viable energy future. As the province navigates this new direction, the success of this policy will depend on effective implementation, ongoing stakeholder engagement, and a commitment to balancing environmental, economic, and social considerations, even as the electricity future debate continues among party leaders.

Biden calls for 100 percent clean electricity by 2035. Here’s how far we have to go.

Biden Clean Energy Plan 2035 accelerates carbon-free electricity with renewables, nuclear, hydropower, and biomass, invests $2T in EVs, grid and energy efficiency, and tightens fuel economy standards beyond the Clean Power Plan.

 

Key Points

A $2T U.S. climate plan for carbon-free power by 2035, boosting renewables, nuclear, EVs, efficiency, and grid upgrades.

✅ Targets a zero-carbon electric grid nationwide by 2035

✅ Includes renewables, nuclear, hydropower, and biomass in standard

✅ Funds EVs, grid modernization, weatherization, and fuel economy rules

 

This month the Democratic presumptive presidential nominee, Joe Biden, outlined an ambitious plan, including Biden’s solar plan to expand clean energy, for tackling climate change that shows how far the party has shifted on the issue since it controlled the White House.

President Barack Obama’s Clean Power Plan had called for the electricity sector to cut its carbon pollution 32 percent by 2030, and did not lay out a trajectory for phasing out oil, coal or natural gas production.

This year, Democratic 2020 hopefuls such as Sen. Bernie Sanders (I-Vt.) went much further, suggesting the United States should derive all of its electricity from renewable sources by 2030, moving to 100% renewables as part of a $16.3 trillion plan to wean the nation away from fossil fuels. Many other congressional Democrats have embraced the Green New Deal — the nonbinding resolution calling for a carbon-free power sector by 2030 and more energy efficient buildings and vehicles, along with a massive investment in electric vehicles and high-speed rail.

Last year, 38 percent of U.S. electricity generated came from clean sources, according to a Washington Post analysis of data from the U.S. Energy Information Administration, and in April renewables hit a record 28% nationwide.

Biden’s new plan, which carries a price tag of $2 trillion, would eliminate carbon emissions from the electric sector by 2035, impose stricter gas mileage standards, fund investments to weatherize millions of homes and commercial buildings, and upgrade the nation’s transportation system. To reach its 2035 carbon-free electricity goal, the campaign includes wind, solar and several forms of energy, acknowledging why the grid isn’t yet 100% renewable while balancing reliability, that are not always counted in state renewable portfolio standards, such as nuclear, hydropower and biomass.

“A great appeal of the Biden proposal is that it is much closer to targeting carbon directly, which is the ultimate enemy, and plays fewer favorites with particular technologies,” said Michael Greenstone, who directs the University of Chicago’s Energy Policy Institute. “This will reduce the costs to consumers and give more carbon bang for the buck.”

But some environmentalists, such as Friends of the Earth President Erich Pica, question the idea of including more controversial carbon-free technologies. “There is no role for nuclear in a least-cost, low carbon world. Including these dinosaurs in a clean energy standard is going to incentivize industry efforts to keep aging, dangerous facilities online,” Pica said in an email.

Hydropower, which relies on a system of moving water that constantly recharges, is defined as renewable by the Environmental Protection Agency. Biomass is often considered as carbon neutral because even though it releases carbon dioxide when it is burned, the plants capture nearly the same amount of CO2 while growing.


Both forms of energy have come under fire for their environmental impacts, however. Damming streams and rivers can destroy fish habitat and make it more difficult for them to spawn, and it also seems unlikely that hydropower will expand its current 6 percent share of the nation’s electrical grid.

Many experts argue that classifying biomass energy as carbon neutral provides an incentive to cut down trees that would otherwise remain standing and sequester carbon. “If burning this wood were good for the climate, then we should not recycle paper, we should burn it,” noted Tim Searchinger, a research scholar at the Princeton School of Public and International Affairs.

Illinois lead the nation in the amount of electricity generated from nuclear power

More than half of the country — 30 states, Washington, and three territories — have adopted a renewable portfolio standard (RPS), according to the National Conference of State Legislatures, and seven states and one territory have set renewable energy goals. While 14 states, along with the District, Puerto Rico and the Virgin Islands, have established requirements of 50 percent or more carbon-free electricity, nearly as many have set theirs at 15 percent or less.

Maine Gov. Janet Mills (D), who has called for 100% renewable electricity in the state, has pushed clean electricity aggressively since taking office in 2019, lifting a wind energy moratorium imposed by her predecessor and signing bills aimed at expanding the state’s carbon-free energy sources. Biomass accounts for a quarter of the state’s electricity, more than any other state.

New York has one of the country’s most ambitious climate targets, which it scaled up last year. It aims to obtain 70 percent of its power from renewable sources within a decade, a period when renewables surpassed coal in U.S. generation, and eliminate carbon altogether by 2040, even as the state is in the process of shutting down a major nuclear plant near New York City, Indian Point, which is slated to cease operating on April 30, 2021.

... while other states are weakening theirs

Last year, Ohio weakened its renewable energy standard from a target of 12.5 percent in 2027 to 8.5 percent by 2026, even as renewables topped coal nationwide for the first time in over a century, without setting any future goals, and jettisoned its energy efficiency standard. West Virginia — which established modest renewable requirements in 2009 — repealed them altogether in 2015, the year they were set to take effect.

Europe Stores Electricity in Natural Gas Pipes

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

 

Key Points

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

✅ Enables hydrogen injection into existing natural gas networks

✅ Balances grids and provides seasonal energy storage capacity

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

 

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Experiment Shows We Can Actually Generate Electricity From The Night Sky

Nighttime thermoradiative power converts outgoing infrared radiation into electricity using semiconductor photodiodes, leveraging negative illumination and sky cooling to harvest renewable energy from Earth-to-space heat flow when solar panels rest, regardless of weather.

 

Key Points

Nighttime thermoradiative power converts Earth's outgoing infrared heat into electricity using semiconductor diodes.

✅ Uses negative illumination to tap Earth-to-space heat flow

✅ Infrared semiconductor photodiodes generate small nighttime current

✅ Theoretical output ~4 W/m^2; lab demo reached 64 nW/m^2

 

There's a stark contrast between the freezing temperatures of space and the relatively balmy atmosphere of Earth, and that contrast could help generate electricity, scientists say – and alongside concepts such as space-based solar power, utilizing the same optoelectronic physics used in solar panels. The obvious difference this would have compared with solar energy is that it would work during the night time, a potential source of renewable power that could keep on going round the clock and regardless of weather conditions.

Solar panels are basically large-scale photodiodes - devices made out of a semiconducting material that converts the photons (light particles) coming from the Sun into electricity by exciting electrons in a material such as silicon, while concepts like space solar beaming could complement them during adverse weather.

In this experiment, the photodiodes work 'backwards': as photons in the form of infrared radiation - also known as heat radiation - leave the system, a small amount of energy is produced, similar to how raindrop electricity harvesting taps ambient fluxes in other experiments.

This way, the experimental system takes advantage of what researchers call the "negative illumination effect" – that is, the flow of outgoing radiation as heat escapes from Earth back into space. The setup explained in the new study uses an infrared semiconductor facing into the sky to convert this flow into electrical current.

"The vastness of the Universe is a thermodynamic resource," says one of the researchers, Shanhui Fan from Stanford University in California.

"In terms of optoelectronic physics, there is really this very beautiful symmetry between harvesting incoming radiation and harvesting outgoing radiation."

It's an interesting follow-up to a research project Fan participated in last year: a solar panel that can capture sunlight while also allowing excess heat in the form of infrared radiation to escape into space.

In the new study, this "energy harvesting from the sky" process can produce a measurable amount of electricity, the researchers have shown – though for the time being it's a long way from being efficient enough to contribute to our power grids, but advances in peer-to-peer energy sharing could still make niche deployments valuable.

In the team's experiments they were able to produce 64 nanowatts per square metre (10.8 square feet) of power – only a trickle, but an amazing proof of concept nevertheless. In theory, the right materials and conditions could produce a million times more than that, and analyses of cheap abundant electricity show how rapidly such advances compound, reaching about 4 watts per square metre.

"The amount of power that we can generate with this experiment, at the moment, is far below what the theoretical limit is," says one of the team, Masashi Ono from Stanford.

When you consider today's solar panels are able to generate up to 100-200 watts per square metre, and in China solar is cheaper than grid power across every city, this is obviously a long way behind. Even in its earliest form, though, it could be helpful for keeping low-power devices and machines running at night: not every renewable energy device needs to power up a city.

Now that the researchers have proved this can work, the challenge is to improve the performance of the experimental device. If it continues to show promise, the same idea could be applied to capture energy from waste heat given off by machinery, and results in humidity-powered generation suggest ambient sources are plentiful.

"Such a demonstration of direct power generation of a diode facing the sky has not been previously reported," explain the researchers in their published paper.

"Our results point to a pathway for energy harvesting during the night time directly using the coldness of outer space."

The research has been published in Applied Physics Letters.

Atlantica - Regulatory Reform To Bring Greener Power To Atlantic Canada

Atlantic Canada Energy Regulatory Reform accelerates smart grids, renewables, hydrogen, and small modular reactors to meet climate targets, enabling interprovincial transmission, EV charging, and decarbonization toward a net-zero grid by 2035 with agile, collaborative policies.

 

Key Points

A policy shift enabling smart grids, clean energy, and transmission upgrades to decarbonize Atlantic Canada by 2035.

✅ Agile rules for smart grids, EV load, and peak demand balancing

✅ Interprovincial transmission: Maritime Link, NB-PEI, Atlantic Loop

✅ Supports hydrogen, SMRs, and renewables to cut GHG emissions

 

Atlantica Centre for Energy Senior Policy Consultant Neil Jacobsen says the future of Atlantic Canada’s electricity grid depends on agile regulations, supported by targeted research such as the $2M Atlantic grid study, that match the pace at which renewable technologies are being developed in the race to meet Canada’s climate goals.

In an interview, Jacobsen stressed the need for a more modernized energy regulatory framework, so the Atlantic Provinces can collaborate to quickly develop and adopt cleaner energy.

To this end, Atlantica released a paper that makes the case for responsive smart grid technology, the adaptation of alternative forms of clean energy, the adaptation of hydrogen as an energy source, petroleum price regulation in Atlantic Canada and small modular reactors.

Jacobsen said regulations need to match Canada’s urgency around reducing greenhouse gas emissions by 40 to 45 percent by 2030, achieving a net-neutral national power grid by 2035 and ultimately a net-zero grid by 2050 in Canada – and the goal that 50 percent of Canadian vehicle sales being electric by 2030.

“It’s an evolution of policy and regulations to adapt to a very aggressive timeline of aggressive climate change and decarbonization targets,” said Jacobsen.

“These are transformational energy and environmental commitments, so the path forward really requires the ability to introduce and adapt and move forward with new clean renewable energy technologies.”

Jacobsen said Atlantica’s recommendations are not a criticism of existing regulations– but an acknowledgment that they need to evolve.

He noted newer, clearer regulations will make way for new energy sources – particularly a region that has the countries highest rates of dependency on fossil fuels and growing climate risks, with Atlantic grids under threat from more intense storms.

“We have a long way to go, but at the same time, we have a lot to celebrate. Atlantic Canada is leading the country in reducing greenhouse gas emissions,” said Jacobsen.

“There are new ways of producing energy that requires us to be able to be much more responsive and this is an opportunity to create a higher level of alignment here, in Atlantic Canada.”

Jacobsen said Atlantica is looking to aid interprovincial cooperation in providing power, echoing calls for a western Canadian grid elsewhere, through projects like the 500-megawatt, 170-kilometre Maritime Link that transports power from the Muskrat Falls hydroelectric dam in Labrador, through Newfoundland and across the Cabot Strait, to Nova Scotia – or NB Power’s export of electricity to P.E.I., via sub-sea cables crossing the Northumberland Strait.

He noted streamlined regulations may allow for more potential wider-scale partnerships, like the proposed Atlantic Loop project, aligning with macrogrid investments that would involve upgrading transmission capacity on the East Coast to allow hydroelectric power from Labrador and Quebec to displace coal use in the region.

Atlantic Canada has led the way with adaption new renewable technologies, noted Jacobsen, referring to nuclear startups Moltex Energy and ARC Nuclear Canada’s efforts to develop small modular nuclear reactor technology in New Brunswick, as well as the potential of adopting hydrogen fuel technology and Nova Scotia’s strides in developing offshore renewable energy.

“I don’t think we have any choice other than to be forceful and aggressive in driving forward a renewable energy agenda.”

Jacobsen said cooperation between the Atlantic provinces is crucial because of how challenging it is to meet energy demand with heavy seasonal and daily variations in energy demand in the region – something smart grid technology could address.

Smart Grid Atlantic is a four-year research and demonstration program testing technologies that provide cleaner local power, support a smarter electricity infrastructure across the region, more renewable power, more information and control over power use and more reliable electricity.

“It can be challenging for utilities to meet those cyclical demands, especially as grids are increasingly exposed to harsh weather across Canada. Smart girds add knowledge of the flow of electrons in a way that can help even out those electricity demands – and quite frankly, those demands will only increase when you look at the electrification of the transportation sector,” he said.

Jacobsen said Atlantica’s paper and call for modernized regulations are only the beginning of a conversation.
