One of the reasons for the controversy regarding the supply of lithium has to do with the different estimates regarding how much is actually needed to power an electric car.

Although they are lumped into one category, hybrid electric vehicles (HEVs) and electric cars are two different beasts with different needs. Even the conversion of a conventional hybrid to a plug-in hybrid electric vehicle (PHEV) is problematic.

In the simplest terms, the demands on batteries in current hybrids are tightly restrained. Unlike the batteries in a flashlight, which run until they are thoroughly depleted, the cells in a hybrid vehicle — whether nickel metal hydride or lithium ion — operate in a very narrow range. To promote extended battery life, auto-makers may engineer them to use as little of 10% of their rated power before demanding they be recharged either by regenerative braking or by the gasoline engine. That's why a conventional hybrid's range of electric power alone is minuscule despite the most frugal driving behaviour. It's also why engineering a plug-in hybrid involves more than adding a wall socket.

The goal of the plug-in is to allow a longer electric-only range and minimize operation of the gasoline portion of the drivetrain. To accomplish this, the existing batteries have to operate through a far greater range of energy dissipation — i.e., allowing their energy levels to reach as low as 30% of reserves.

Experts contend these deeper discharge rates will reduce battery life from an expected eight years to just three. The other alternative is to bump up the battery's size, increasing lithium usage.

Although there are numerous alternative battery technologies being tested, the study of electrons is a relatively mature science. While computer advancements still manage to follow Moore's Law, which states that the number of integrated transistors per integrated circuit (a measure of computing power) would double every two years, battery performance seems to improve at a much more modest pace.

Despite many claims of huge nanotechnology developments, the mass production of a miracle battery may still be some distance in the future.

Siemens Energy to unlock a new era of offshore green hydrogen production

Offshore Wind-to-Hydrogen Integration enables green hydrogen by embedding an electrolyzer in offshore turbines. Siemens Gamesa and Siemens Energy align under H2Mare to decarbonize industry, advance the Paris Agreement, and unlock scalable, off-grid renewable production.

 

Key Points

A method integrating electrolyzers into offshore wind turbines to generate green hydrogen and reduce carbon emissions.

✅ Integrated electrolyzer at turbine base for off-grid operation

✅ Enables scalable, cost-efficient green hydrogen production

✅ Supports decarbonization targets under Paris Agreement

 

To reach the Paris Agreement goals, the world will need vast amounts of green hydrogen and, with offshore wind growth accelerating, wind will provide a large portion of the power needed for its production.

Siemens Gamesa and Siemens Energy announced today that they are joining forces combining their ongoing wind-to-hydrogen developments to address one of the major challenges of our decade - decarbonizing the economy to solve the climate crisis.

The companies are contributing with their developments to an innovative solution that fully integrates an electrolyzer into an offshore wind turbine as a single synchronized system to directly produce green hydrogen. The companies intend to provide a full-scale offshore demonstration of the solution by 2025/2026. The German Federal Ministry of Education and Research, reflecting Germany's clean energy progress, announced today that the developments can be implemented as part of the ideas competition 'Hydrogen Republic of Germany'.

'Our more than 30 years of experience and leadership in the offshore wind industry, coupled with Siemens Energy's expertise in electrolyzers, brings together brilliant minds and cutting-edge technologies to address the climate crisis. Our wind turbines play a huge role in the decarbonization of the global energy system, and the potential of wind to hydrogen means that we can do this for hard-to-abate industries too. It makes me very proud that our people are a part of shaping a greener future,' said Andreas Nauen, Siemens Gamesa CEO.

Christian Bruch, CEO of Siemens Energy, explains: 'Together with Siemens Gamesa, we are in a unique position to develop this game changing solution. We are the company that can leverage its highly flexible electrolyzer technology and create and redefine the future of sustainable offshore energy production. With these developments, the potential of regions with abundant offshore wind, such as the UK offshore wind sector, will become accessible for the hydrogen economy. It is a prime example of enabling us to store and transport wind energy, thus reducing the carbon footprint of economy.'

Over a time frame of five years, Siemens Gamesa plans to invest EUR 80 million and Siemens Energy is targeting to invest EUR 40 million in the developments. Siemens Gamesa will adapt its development of the world's most powerful turbine, the SG 14-222 DD offshore wind turbine to integrate an electrolysis system seamlessly into the turbine's operations. By leveraging Siemens Gamesa's intricate knowledge and decades of experience with offshore wind, electric losses are reduced to a minimum, while a modular approach ensures a reliable and efficient operational set-up for a scalable offshore wind-to-hydrogen solution. Siemens Energy will develop a new electrolysis product to not only meet the needs of the harsh maritime offshore environment and be in perfect sync with the wind turbine, but also to create a new competitive benchmark for green hydrogen.

The ultimate fully integrated offshore wind-to-hydrogen solution will produce green hydrogen using an electrolyzer array located at the base of the offshore wind turbine tower, blazing a trail towards offshore hydrogen production. The solution will lower the cost of hydrogen by being able to run off grid, much like solar-powered hydrogen in Dubai showcases for desert environments, opening up more and better wind sites. The companies' developments will serve as a test bed for making large-scale, cost-efficient hydrogen production a reality and will prove the feasibility of reliable, effective implementation of wind turbines in systems for producing hydrogen from renewable energy.

The developments are part of the H2Mare initiative which is a lighthouse project likely to be supported by the German Federal Ministry of Education and Research ideas competition 'Hydrogen Republic of Germany'. The H2mare initiative under the consortium lead of Siemens Energy is a modular project consisting of multiple sub-projects to which more than 30 partners from industry, institutes and academia are contributing. Siemens Energy and Siemens Gamesa will contribute to the H2Mare initiative with their own developments in separate modular building blocks.

About hydrogen and its role in the green energy transition

Currently 80 million tons of hydrogen are produced each year and production is expected to increase by about 20 million tons by 2030. Just 1% of that hydrogen is currently generated from green energy sources. The bulk is obtained from natural gas and coal, emitting 830 million tons of CO2 per year, more than the entire nation of Germany or the global shipping industry. Replacing this current polluting consumption would require 820 GW of wind generating capacity, 26% more than the current global installed wind capacity. Looking further ahead, many studies suggest that by 2050 production will have grown to about 500 million tons, with a significant shift to green hydrogen already signaled by projects like Brazil's green hydrogen plant now underway. The expected growth will require between 1,000 GW and 4,000 GW of renewable capacity by 2050 to meet demand, and in the U.S. initiatives like DOE hydrogen hubs aim to catalyze this build-out, which highlights the vast potential for growth in wind power.

SDG&E Wants More Money From Customers Who Don’t Buy Much Electricity. A Lot More.

SDG&E Minimum Bill Proposal would impose a $38.40 fixed charge, discouraging rooftop solar, burdening low income households, and shifting grid costs during peak demand, as the CPUC weighs consumer impacts and affordability.

 

Key Points

Sets a $38.40 monthly minimum bill that raises low usage costs, deters rooftop solar, and burdens low income households.

✅ $38.40 fixed charge regardless of usage

✅ Disincentivizes rooftop solar investments

✅ Disproportionate impact on low income customers

 

The utility San Diego Gas & Energy has an aggressive proposal pending before the California Public Utilities Commission, amid recent commission changes in San Diego that highlight how regulatory decisions affect local customers: It wants to charge most residential customers a minimum bill of $38.40 each month, regardless of how much energy they use. The costs of this policy would hit low-income customers and those who generate their own energy with rooftop solar. We’re urging the Commission to oppose this flawed plan—and we need your help.

SDG&E’s proposal is bad news for sustainable energy. About half of the customers whose bills would go up under this proposal have rooftop solar. The policy would deter other customers from investing in rooftop solar by making these investments less economical. Ultimately, lost opportunities for solar would mean burning more gas in polluting power plants. 

The proposal is also bad news for people who already have to scrimp on energy costs. Most customers with big homes and billowing air conditioners won't notice if this policy goes into effect, because they use at least $38 worth of electricity a month anyway. But for households that don’t buy much electricity from the company, including those in small apartments without air conditioning, this proposal would raise the bills. Even for customers on special low-income rates, amid electric bill changes statewide, SDG&E wants a minimum bill of $19.20.

Penalizing customers who don’t use much electricity would disproportionately hurt lower-income customers, raising energy equity concerns across the region, who tend to use less energy than their wealthier neighbors. In the region SDG&E serves, the average family in an apartment uses half as much electricity as a single-family residence. Statewide, low-income households are more than four times as likely to be low-usage electricity customers than high-income households. When it gets hot, residential electricity patterns are often driven by air conditioning. The vast majority of SDG&E's customers live in the coastal climate zone, where access to air conditioning is strongly linked to income: Households with incomes over $150,000 are more than twice as likely to have air conditioning than families making less than $35,000, with significant racial disparities in who has AC.

In its attempt to rationalize its request, SDG&E argues that it should charge everyone for infrastructure costs that do not depend on how much energy they use. But the cost of the grid is driven by how much energy SDG&E delivers on hot summer afternoons, when some customers blast their AC and demand for electricity peaks. If more customers relied on their own solar power or conserved energy, the utility would spend less on its grid and help rein in soaring electricity prices over time.

In the long term, reducing incentives to go solar and conserve energy will strain the grid and drive up costs for everyone, especially as lawmakers may overturn income-based charges and reshape rate design. SDG&E's arguments are part of a standard utility playbook for trying to hike income-based fixed charges, and consumer advocates have repeatedly shut them down.  As far as we know, no regulators in the country have allowed a utility to charge customers over $38 for the “privilege” of accessing electric service.

Amazon launches new clean energy projects in US, UK

Amazon Renewable Energy Projects advance net zero goals with a Scotland wind farm PPA and US solar farms in North Carolina and Virginia, delivering clean power, added capacity, and lower carbon emissions across cloud operations.

 

Key Points

Amazon initiatives adding wind and solar capacity in the UK and US to cut carbon and power cloud operations.

✅ Largest UK corporate wind PPA on Scotland Kintyre Peninsula

✅ Two US solar farms in North Carolina and Virginia

✅ 265 MW added capacity, 668,997 MWh clean power annually

 

Amazon is launching three renewable energy projects in the United States and the United Kingdom that support Amazon’s commitment to using net zero carbon energy by 2040.

The U.K. project is a wind farm on the Kintyre Peninsula in Scotland, aligned with a 10 GW renewables contract boosting the U.K. grid. It will generate 168,000 megawatt hours (MWh) of clean energy each year, enough to power 46,000 U.K. homes. It will be the largest corporate wind power purchase agreement (PPA) in the U.K.

Offshore wind energy in the UK is powering up rapidly, complementing onshore developments.

The other two are solar projects – one in Warren County, N.C, and the other in Prince George County, Va, reflecting broader US solar and wind growth trends nationwide. Together, they are expected to generate 500,997 MWh of energy annually. It is Amazon’s second renewable energy project in North Carolina, following the Amazon Wind Farm US East operated by Avangrid Renewables, and eighth in Virginia.

The three new Amazon wind and solar projects – which are expected to be in operation in 2012 — will provide 265 MW of additional renewable capacity, and align with U.K. wind power lessons for the U.S. market nationwide.

“In addition to the environmental benefits inherently associated with running applications in the cloud, Amazon is committed to minimizing our carbon emissions and reaching 80% renewable energy use across the company by 2024. We’ve announced eight projects this year and have more projects on the horizon – and we’re committed to investing in renewable energy as a critical step toward addressing our carbon footprint globally,” Kara Hurst, director of sustainability at Amazon, said. “With nearly 70 renewable energy projects around the globe – including 54 solar rooftops – we are making significant progress towards reaching Amazon’s company-wide commitment to reach 100% renewable energy by 2030.”

Amazon has launched 18 utility-scale wind and solar renewable energy projects to date, and in parallel, Duke Energy Renewables has acquired three California solar projects, underscoring sector momentum. They will generate over 1,600 MW of renewable capacity and deliver more than 4.6 million MWh of clean energy annually. Amazon has also installed more than 50 solar rooftops on fulfillment centers and sort centers around the world. They generate 98 MW of renewable capacity and deliver 130,000 MWh of clean energy annually.

“Today’s announcement by Amazon is another important step for North Carolina’s clean energy plan that will increase our reliance on renewables and reduce our greenhouse gas emissions,” North Carolina Governor Roy Cooper said. “Not only is this the right thing to do for our planet, it’s the right thing to do for our economy. More clean energy jobs means better jobs for North Carolina families.”

Amazon reports on its sustainability commitments, initiatives, and performance on a new web site the company recently launched. It includes information on Amazon’s carbon footprint and other metrics and updates the company’s progress towards reaching The Climate Pledge. 

“It’s wonderful to see the announcement of these new projects, helping bring more clean energy to the Commonwealth of Virginia where Amazon is already recognized as a leader in bringing renewable energy projects online,” Virginia Governor Ralph Northam said. “These solar farms help reaffirm the Commonwealth’s role as a leading producer of clean energy in the U.S., helping take the nation forward in responding to climate change.”

Report: Solar ITC Extension Would Be ‘Devastating’ for US Wind Market

Solar ITC Impact on U.S. Wind frames how a 30% solar investment tax credit could undercut wind PTC economics, shift corporate procurement, and, without transmission and storage, slow onshore builds despite offshore wind momentum.

 

Key Points

It is how a solar ITC extension may curb U.S. wind growth absent PTC parity, transmission, storage, and offshore backing.

✅ ITC at 30% risks shifting corporate procurement to solar.

✅ Post-PTC wind faces grid, transmission, and curtailment headwinds.

✅ Offshore wind, storage pairing, TOU demand could offset.

 

The booming U.S. wind industry, amid a wind power surge, faces an uncertain future in the 2020s. Few factors are more important than the fate of the solar ITC.

An extension of the solar investment tax credit (ITC) at its 30 percent value would be “devastating” to the future U.S. wind market, according to a new Wood Mackenzie report.

The U.S. is on track to add a record 14.6 gigawatts of new wind capacity in 2020, despite Covid-19 impacts, and nearly 39 gigawatts during a three-year installation boom from 2019 to 2021, according to Wood Mackenzie’s 2019 North America Wind Power Outlook.

But the market’s trajectory begins to look highly uncertain from the early 2020s onward, and solar is one of the main reasons why.

Since the dawn of the modern American renewables market, the wind and solar sectors have largely been allies on the national stage, benefiting from many of the same favorable government plans and sharing big-picture goals. Until recently, wind and solar companies rarely found themselves in direct competition.

But the picture is changing as solar catches up to wind on cost and the grid penetration of renewables surges. What was once a vague alliance between the two fastest growing renewables technologies could morph into a serious rivalry.

While many project developers are now active in both sectors, including NextEra Energy Resources, Invenergy and EDF, the country’s thriving base of wind manufacturers could face tougher days ahead.

 

The ITC's inherent advantage

At this point, wind remains solar’s bigger sibling in many ways.

The U.S. has nearly 100 gigawatts of installed wind capacity today, compared to around 67 gigawatts of solar. With their substantially higher capacity factors, wind farms generated four times more power for the U.S. grid last year than utility-scale solar plants, for a combined wind-solar share of 8.2 percent, according to government figures, even as renewables are projected to reach one-fourth of U.S. electricity generation. (Distributed PV systems further add to solar’s contribution.)

But it's long been clear that wind would lose its edge at some point. The annual solar market now regularly tops wind. The cost of solar energy is falling more rapidly, and appears to have more runway for further reduction. Solar’s inherent generation pattern is more valuable in many markets, delivering power during peak-demand hours, while the wind often blows strongest at night.

 

And then there’s the matter of the solar ITC.

In 2015, both wind and solar secured historic multi-year extensions to their main federal subsidies. The extensions gave both industries the longest period of policy clarity they’ve ever enjoyed, setting in motion a tidal wave of installations set to crest over the next few years.

Even back in 2015, however, it was clear that solar got the better deal in Washington, D.C.

While the wind production tax credit (PTC) began phasing down for new projects almost immediately, solar developers were given until the end of 2019 to qualify projects for the full ITC.

And critically, while the wind PTC drops to nothing after its sunset, commercially owned solar projects will remain eligible for a 10 percent ITC forever, based on the existing legislation. Over time, that amounts to a huge advantage for solar.

In another twist, the solar industry is now openly fighting for an extension of the 30 percent ITC, while the wind industry seemingly remains cooler on the prospect of pushing for a similar prolongation — having said the current PTC extension would be the last.

 

Plenty of tailwinds, too

Wood Mackenzie's report catalogues multiple factors that could work for or against the wind market in the "uncharted" post-PTC years, many of them, including the Covid-19 crisis, beyond the industry’s direct control.

If things go well, annual installations could bounce back to near-record levels by 2027 after a mid-decade contraction, the report says. But if they go badly, installations could remain depressed at 4 gigawatts or below from 2022 through most of the coming decade, and that includes an anticipated uplift from the offshore market.

An extension of the solar ITC without additional wind support would “severely compound” the wind market’s struggle to rebound in the 2020s, the report says. The already-evident shift in corporate renewables procurement from wind to solar could intensify dramatically.

The other big challenge for wind in the 2020s is the lack of progress on transmission infrastructure that would connect potentially massive low-cost wind farms in interior states with bigger population centers. A hoped-for national infrastructure package that might address the issue has not materialized.

Even so, many in the wind business remain cautiously optimistic about the post-PTC years, with a wind jobs forecast bolstering sentiment, and developers continue to build out longer-term project pipelines.

Turbine technology continues to improve. And an extension of the solar ITC is far from assured.

Other factors that could work in wind’s favor in the years ahead include:

The nascent offshore sector, which despite lingering regulatory uncertainty at the federal level looks set to blossom into a multi-gigawatt annual market by the mid-2020s, in line with an offshore wind forecast that highlights substantial growth potential. Lobbying efforts for an offshore wind ITC extension are gearing up, offering a potential area for cooperation between wind and solar.

The potential linkage of policy support for energy storage to wind projects, building on the current linkage with solar.

Growing electric vehicle sales and a shift toward time-of-use retail electricity billing, which could boost power demand during off-peak hours when wind generation is strong.

The land-use advantages wind farms have over solar in some agricultural regions.

This kite could harness more of the world's wind energy

Autonomous Energy Kites harness offshore wind on floating platforms, using carbon fiber wings, tethers, and rotors to generate grid electricity; an airborne wind energy solution backed by Alphabet's Makani to cut turbine costs.

 

Key Points

Autonomous Energy Kites are tethered craft that capture winds with rotors, generating grid power from floating platforms.

✅ Flies circles on tethers; rotors drive generators to feed the grid.

✅ Operates over deep-sea winds where fixed turbines are impractical.

✅ Lighter, less visual impact, and lower installation costs offshore.

 

One company's self-flying energy kite may be the answer to increasing wind power around the world, alongside emerging wave power solutions as well.

California-based Makani -- which is owned by Google's parent company, Alphabet -- is using power from the strongest winds found out in the middle of the ocean, where the offshore wind sector has huge potential, typically in spots where it's a challenge to install traditional wind turbines. Makani hopes to create electricity to power communities across the world.

Despite a growing number of wind farms in the United States and the potential of this energy source, lessons from the U.K. underscore how to scale, yet only 6% of the world's electricity comes from wind due to the the difficulty of setting up and maintaining turbines, according to the World Wind Energy Association.

When the company's co-founders, who were fond of kiteboarding, realized deep-sea winds were largely untapped, they sought to make that energy more accessible. So they built an autonomous kite, which looks like an airplane tethered to a base, to install on a floating platform in water, as part of broader efforts to harness oceans and rivers for power across regions. Tests are currently underway off the coast of Norway.

"There are many areas around the world that really don't have a good resource for renewable power but do have offshore wind resources," Makani CEO Fort Felker told Rachel Crane, CNN's innovation correspondent. "Our lightweight kites create the possibility that we could tap that resource very economically and bring renewable power to hundreds of millions of people."

This technology is more cost-efficient than a traditional wind turbine, which is a lot more labor intensive and would require lots of machinery and installation.

The lightweight kite, which is made of carbon fiber, has an 85-foot wingspan. The kite launches from a base station and is constrained by a 1,400-foot tether as it flies autonomously in circles with guidance from computers. Crosswinds spin the kite's eight rotors to move a generator that produces electricity that's sent back to the grid through the tether.

The kites are still in the prototype phase and aren't flown constantly right now as researchers continue to develop the technology. But Makani hopes the kites will one day fly 24/7 all year round. When the wind is down, the kite will return to the platform and automatically pick back up when it resumes.

Chief engineer Dr. Paula Echeverri said the computer system is key for understanding the state of the kite in real time, from collecting data about how fast it's moving to charting its trajectory.

Echeverri said tests have been helpful in establishing what some of the challenges of the system are, and the team has made adjustments to get it ready for commercial use. Earlier this year, the team successfully completed a first round of autonomous flights.

Working in deeper water provides an additional benefit over traditional wind turbines, according to Felker. By being farther offshore, the technology is less visible from land, and the growth of offshore wind in the U.K. shows how coastal communities can adapt. Wind turbines can be obtrusive and impact natural life in the surrounding area. These kites may be more attractive to areas that wish to preserve their scenic coastlines and views.

It's also desirable for regions that face constraints related to installing conventional turbines -- such as island nations, where World Bank support is helping developing countries accelerate wind adoption, which have extremely high prices for electricity because they have to import expensive fossil fuels that they then burn to generate electricity.

Makani isn't alone in trying to bring novelty to wind energy. Several others companies such as Altaeros Energies and Vortex Bladeless are experimenting with kites of their own or other types of wind-capture methods, such as underwater kites that generate electricity, a huge oscillating pole that generates energy and a blimp tethered to the ground that gathers winds at higher altitudes.

Nova Scotia Power delays start of controversial new charge for solar customers

Nova Scotia Power solar charge proposes an $8/kW monthly system access fee on net metering customers, citing grid costs. UARB review, carbon credits, rate hikes, and solar industry impacts fuel political and consumer backlash.

 

Key Points

A proposed $8/kW monthly grid access fee on net metered solar customers, delayed to Feb 1, 2023, pending UARB review.

✅ $8/kW monthly system access fee on net metering

✅ Delay to Feb 1, 2023 after industry and political pushback

✅ UARB review; debate over grid costs and carbon credits

 

Nova Scotia Power has pushed back by a year the start date of a proposed new charge for customers who generate electricity and sell it back to the grid, following days of concern from the solar industry and politicians worried that it will damage the sector.

The company applied to the Nova Scotia Utility and Review Board (UARB) last week for various changes, including a "system access charge" of $8 per kilowatt monthly on net metered installations, and the province cannot order the utility to lower rates under current law. The vast majority of the province's 4,100 net metering customers are residential customers with solar power, according to the application. 

The proposed charge would have come into effect Tuesday if approved, but Nova Scotia Power said in a news release Tuesday it will change the date in its filing from Feb. 1, 2022, to Feb. 1, 2023.

"We understand that the solar industry was taken off guard," utility CEO Peter Gregg said in an interview.

"There could have been an opportunity to have more conversations in advance."

Gregg said the utility will meet with members of the solar industry over the next year to work on finding solutions that support the sector's growth, while addressing what NSP sees as an inequity in the net metering system.

NSP recognized that customers who choose solar invest a significant amount and pay for the electricity they use, but they don't pay for costs associated with accessing the electrical grid when they need energy, such as on cold winter evenings when the sun is not shining.

"I know that's hit a nerve, but it doesn't take away the fact that it is an issue," Gregg said.

He said this is an issue utilities are navigating around North America, where seasonal rate designs have sparked consumer backlash in New Brunswick, and NSP is open to hearing ideas for other models of charges or fees.

The utility's suggested system access charge closely resembles one proposed in California, which has also raised major concerns from the solar industry and been criticized by the likes of Elon Musk, and has parallels to Massachusetts solar demand charges as well.

Although the "solar profile" of Nova Scotia and California is very different, with far more solar customers in that state, and in other provinces such as Saskatchewan, NDP criticism of 8% hikes has intensified affordability debates, Gregg said the fundamental issues are the same.

For those with a typical 10-kilowatt solar system, which generates around $1,800 of electricity a year, the new charge would mean those customers would be required to pay $960 back to NSP. That would roughly double the length of time it takes for those customers to pay off their investment for the panels.

David Brushett, chair of Solar Nova Scotia, said he relayed concerns from solar installers and others in the industry to Gregg on Monday. 

Brushett said the year delay is a positive first step, but he is still calling on the province to take a strong stance against the application, which has led to customers cancelling their panel installations and companies considering layoffs.

"There's still an urgency to this situation that hasn't been addressed, and we need to kind of protect the industry," he said Tuesday.

NSP's original application proposed exempting net metering customers who enrolled before Feb. 1, 2022, from the charge for 25 years after they sign up. But any benefit would be lost if those customers sold their home, and the exemption wouldn't extend to the new buyers, said Brushett.


Carbon offsets missing from equation: industry
Brushett said NSP "completely ignored" the fact that it's getting free carbon offset credits from homeowners who use solar energy under the provincial cap and trade program.

If the net metering system continues as is, NSP has said non-solar customers would pay about $55 million between now and 2030. That number assumes about 2,000 people sign up for net metering each year over the next nine years.

When asked whether those carbon emission credits were factored into the calculations for the proposed charge, Gregg said, "I don't believe in the current structure it is, but it's something that certainly we'd be open to hearing about."

Brushett said his group is finalizing a legal response to NSP's proposal and has already filed an official complaint against the company with the UARB.


Base charge on actual electrical output: customer
At least one shareholder in NSP parent company Emera is considering selling his shares in response to the application.

Joe Hood, a shareholder from Middle Sackville, said the proposed charge won't apply to his existing 11.16-kilowatt solar system, but if it did, it would cost him $1,071 a year.

"I am offended that a company I would invest in would do this to the solar industry in Nova Scotia," he said.

According to his meter, Hood said he pushed 9,600 kilowatt hours of solar electricity to the grid last year— some only for a brief period, and all of which was used by his home by the end of the year.

Under the proposed charge, someone with one solar panel who goes away on vacation in the summer would push all their electricity to the grid, and be charged far less than someone with 10 panels who has used all their own power and hasn't pushed anything.

"Nova Scotia Power's argument is that it's an issue with the grid. Well, then it should be based on what touches the grid," Hood said.

Far from actually making the system fair for everyone, Hood said this charge places solar only in the hands of the super-rich or NSP, with projects like its community solar gardens in Amherst, N.S.


Green Party suggests legislation update
Nova Scotia's Green Party also said Tuesday that Gregg's arguments of fairness are misleading, echoing earlier premier opposition to a 14% hike on rates.

The party is calling for an update to the Electricity Act that would "prevent penalizing any activity that helps Nova Scotia reach its emissions target," aligning with calls to make the electricity system more accountable to residents.

In its application, NSP has also asked to increase electricity rates for residential customers by at least 10 per cent over the next three years, amid debate that culminated in a 14% rate hike approval by regulators. 

The company wants to maintain its nine per cent rate of return.

NSP expects to earn $153 million this year, $192 million in 2023, and $213 million in 2024 from its rate of return.
