Abitibi hydro assets sold to unnamed buyer

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

Key Points

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

✅ Hydropower deliveries reduce need for biomass on the grid

✅ Biomass is inefficient, costly, and impacts biodiversity

✅ District heating offers better use of forestry residuals

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

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

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

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

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

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

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

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

But to Plourde, that explanation doesn't wash.

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

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

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

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

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

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

Cloud Data Centers Environmental Impact highlights massive electricity use, carbon emissions, and cooling demands, with coal-heavy grids in China; big tech shifts to renewable energy, green data centers, and cooler climates to boost sustainability.

Key Points

Energy use, emissions, and cooling load of cloud systems, and shifts to renewables to reduce climate impact.

✅ Global data centers use 3-5% of electricity, akin to airlines

✅ Cooling drives energy demand; siting in cool climates saves power

✅ Shift from coal to renewables lowers CO2 and improves PUE

A hidden environmental price makes storing data in the cloud a costly convenience.

Between 3 to 5% of all electricity used globally comes from data centers that house massive computer systems, with computing power forecasts warning consumption could climb, an amount comparable to the airline industry, says Ben Brock Johnson, Here & Now’s tech analyst.

Instead of stashing information locally on our own personal devices, the cloud allows users to free up storage space by sending photos and files to data centers via the internet.

The cloud can also use large data sets to solve problems and host innovative technologies that make cities and homes smarter, but storing information at data centers uses energy — a lot of it.

"Ironically, the phrase 'moving everything to the cloud' is a problem for our actual climate right now," Johnson says.

A new study from Greenpeace and North China Electric Power University reports that in five years, China's data centers alone will consume as much power as the total amount used in Australia in 2018. The industry's electricity consumption is set to increase by 66% over that time.

Buildings storing data produced 99 million metric tons of carbon last year in China, the study finds, with SF6 in electrical equipment compounding warming impacts, which is equivalent to 21 million cars.

The amount of electricity required to run a data center is a global problem, but in China, 73% of these data centers run on coal, even as coal-fired electricity is projected to fall globally this year.

The Chinese government started a pilot program for green data centers in 2015, which Johnson says signals the country is thinking about the environmental consequences of the cloud.

"Beijing’s environmental awareness in the last decade has really come from a visible impact of its reliance on fossil fuels," he says. "The smog of Chinese cities is now legendary and super dangerous."

The country's solar power innovations have allowed the country to surpass the U.S. in cleantech, he says.

Chinese conglomerate Alibaba Group has launched data centers powered by solar and hydroelectric power.

"While I don't know how committed the government is necessarily to making data centers run on clean technology," Johnson says. "I do think it is possible that a larger evolution of the government's feelings on environmental responsibility might impact this newer tech sector."

In the U.S., there has been a big push to make data centers more sustainable amid warnings that the electric grid is not designed for mounting climate impacts.

Canada has made notable progress decarbonizing power, with nationwide electricity gains supporting cleaner data workloads.

Apple now says all of its data centers use clean energy. Microsoft is aiming for 70% renewable energy by 2023, aligning with declining power-sector emissions as producers move away from coal.

Amazon is behind the curve, for once, with about 50%, Johnson says. Around 1,000 employees are planning to walk out on Sept. 20 in protest of the company’s failure to address environmental issues.

"Environmental responsibility fits the brand identities these companies want to project," he says. "And as large tech companies become more competitive with each other, as Apple becomes more of a service company and Google becomes a device company, they want to convince users more and more to think of them as somehow different even if they aren't."

Google and Facebook are talking about building data centers in cooler places like Finland and Sweden instead of hot deserts like Nevada, he says.

In Canada, cleaning up electricity is critical to meeting climate pledges, according to recent analysis.

Computer systems heat up and need to be cooled down by air conditioning units, so putting a data center in a warm climate will require greater cooling efforts and use more energy.

In China, 40% of the electricity used at data centers goes toward cooling equipment, according to the study.

The more data centers consolidate, Johnson says they can rely on fewer servers and focus on larger cooling efforts.

But storing data in the cloud isn't the only way tech users are unknowingly using large amounts of energy: One Google search requires an amount of electricity equivalent to powering a 60-watt light bulb for 17 seconds, magazine Yale Environment 360 reports.

"In some ways, we're making strides even as we are creating a bigger problem," he says. "Which is like, humanity's MO, I guess."

Nova Scotia Cap-and-Trade Program joins Western Climate Initiative to leverage emissions trading IT systems, track allowances, and manage compliance, while setting in-province caps, carbon pricing signals, and third-party verified reporting for industrial and fuel suppliers.

Key Points

A provincial emissions trading system using WCI services to cap GHGs, track allowances, and enforce verified compliance.

✅ Uses WCI IT system to manage allowances and registry

✅ Initial trading limited to in-province participants

✅ Third-party verification and annual reporting deadlines

Nova Scotia is yet to set targets for its new cap and trade regime to reduce greenhouse gases, but the province announced Monday that it has joined the Western Climate Initiative Inc. -- a non-profit corporation formed to provide administrative and technical services to states and provinces with emissions trading programs.

Environment Minister Iain Rankin said joining the initiative would allow the province to use its IT system to manage and track its new cap and trade program.

Rankin said the province can join without trading greenhouse gas emission allowances with other jurisdictions -- California, Quebec, and Ontario are currently linked through the program, with Hydro-Québec's U.S. sales highlighting cross-border dynamics. Nova Scotia currently has no plans to trade outside the province as it works on emissions caps Rankin said will be ready sometime in June.

Nova Scotia is yet to set targets for its new cap and trade regime to reduce greenhouse gases, but the province announced Monday that it has joined the Western Climate Initiative Inc. -- a non-profit corporation formed to provide administrative and technical services to states and provinces with emissions trading programs.

Environment Minister Iain Rankin said joining the initiative would allow the province to use its IT system to manage and track its new cap and trade program.

Rankin said the province can join without trading greenhouse gas emission allowances with other jurisdictions -- California, Quebec, and Ontario are currently linked through the program. Nova Scotia currently has no plans to trade outside the province as it works on emissions caps Rankin said will be ready sometime in June.

"By keeping our system internal it ensures that our greenhouse gas reductions are happening within our province," said Rankin. "But we do have that opportunity (to join) and if there are new entrants or we need more access to credits then that may shift our strategy."

The use of the system will cost Nova Scotia about US$314,000 for 2018-19, with an annual cost in subsequent years of about US$228,000 or more, if the province requests modifications.

"If we were to do something like that internally we would have to build a full database and hire more people, so this was an obvious choice for us," said Rankin.

Nova Scotia has already met the national reduction target of 30 per cent below 2005 levels and says it's on track to have 40 per cent of electricity generation from renewables by 2020, underscoring how cleaning up Canada's electricity supports climate pledges.

Stephen Thomas, energy campaign coordinator for the Ecology Action Centre, called the province's move an "important small step," stressing the importance of using the same administrative rules as the other jurisdictions involved.

But Thomas said Nova Scotia should go further and trade emissions with California, Quebec, and Ontario, and also put a price on carbon by auctioning credits as they do.

Thomas said Nova Scotia's system stands to be volatile because of the smaller number of participants -- about 20 including Nova Scotia Power, Northern Pulp, Lafarge, and large oil and gasoline companies such as ExxonMobil, Imperial and Irving.

"It's very likely to favour Nova Scotia Power as the largest single emitter with the most credits to sell here, and that would change if we had a linked system, at a time when Canada will need more electricity to hit net-zero according to the IEA," Thomas said.

He said it's important to have a linked system and a regional approach in Atlantic Canada, which has more emissions per person and more emissions per GDP than places like Ontario, Quebec and California, and where policies like Newfoundland's rate reduction plan can influence electricity strategy.

"Reducing emissions, because we are so emissions-intensive here, is a little bit cheaper," said Thomas. "So it's possible that Ontario, Quebec and California could pay Nova Scotia to reduce its emissions."

Under its program, Nova Scotia requires industrial facilities generating 50,000 tonnes or more of greenhouse gas emissions per year to report emissions.

Regulations also cover petroleum product suppliers that import or produce 200 litres of fuel or more per year for consumption and natural gas distributors whose products produce at least 10,000 tonnes of greenhouse gas emissions a year.

Companies were to have reported to the Environment Department by May 1 but Rankin said the deadline has been pushed back to June 1, a deadline that was to be followed in subsequent years in any event. Reports must be verified by a third party by Sept. 1 every year.

The Liberal government passed enabling legislation for cap and trade last fall.

As for the upcoming emissions caps, Rankin isn't tipping the province's hand yet, even as B.C.'s 2050 targets face a shortfall in some forecasts.

"Those caps will recognize the investments that have already been made and therefore will be the most cost-effective program that we can put together to meet the federal requirement," he said.

Alberta Solar Energy Contracts secure low-cost photovoltaic PPAs for government operations, delivering renewable electricity at 4.8 cents/kWh, beating natural gas LCOE, enhancing summer grid efficiency across Hays, Tilley, and Jenner with Canadian Solar.

Key Points

Low-cost PV power agreements meeting 55% of Alberta government electricity demand via new Canadian Solar facilities.

✅ Price: 4.8 cents/kWh CAD, under gas-fired generation LCOE.

✅ Sites: Hays, Tilley, Jenner; 50% equity with Conklin Métis Local #193.

✅ Supplies 55% of provincial government electricity demand.

Three new solar electricity facilities to be built in south eastern Alberta (Canada) amid Alberta's solar growth have been selected through a competitive process to supply the Government of Alberta with 55 per cent of their annual electricity needs. The facilities will be built near Hays, Tilley, and Jenner, by Canadian Solar with Conklin Métis Local #193 as 50-percent equity owners.

The Government of Alberta's operations have been powered 100 per cent with wind power since 2007. Upon the expiration of some of these contracts, they have been renewed to switch from wind to solar energy. The average contract pricing will be $0.048 per kilowatt hour (3.6 cents/kWh USD), which is less than the average historical wholesale power pool price paid to natural gas-fired electricity in the province in years 2008 - 2018.

"The conversation about solar energy has long been fixated on its price competitiveness with fossil fuels," said John Gorman, CanSIA President & CEO. "Today's announcement demonstrates that low cost solar energy has arrived as a mainstream option in Alberta, even as demand for solar lags in Canada according to federal assessments. The conversation should next focus on how to optimize an all-of-the-above strategy for developing the province's renewable and non-renewable resources."

"This price discovery is monumental for the solar industry in Canada" said Patrick Bateman, CanSIA Director of Policy & Market Development. "At less than five cents per kilowatt hour, this solar electricity has a cost that is less than that of natural gas. Achieving Alberta's legislated 30 per cent by 2030 renewable electricity target just became a whole lot cheaper!".

Quick Facts:

• The contract price of 4.8 cents/kWh CAD to be paid by Alberta Infrastructure for this solar electricity represents a lower Levelized Cost of Electricity (LCOE) than the average annual wholesale price paid by the power pool to combined-cycle and single-cycle natural gas-fired electricity generation which was 7.1 cents/kWh and 11.2 cents/kWh respectively from 2008 - 2018.

• Alberta receives more hours of sunshine than Miami, Florida in the summer months. Alberta's electricity supply is most strained in summer, highlighting challenges for solar expansion when high temperatures increase the resistance of the distribution and transmission systems, and reduce the efficiency of cooling thermal power plants. For this reason, solar facilities sited near to electricity demand improves overall grid efficiency. Supply shortages are atypical in Alberta in winter when solar energy is least available. When they do occur, imports are increased and large loads are decreased.

• In 2018, Alberta's solar electricity generation exceeded 50 MW. While representing much less than 1% of the province's electricity supply today, the Canadian Solar Industries Association (CanSIA) forecasts that solar energy could supply as much as 3 per cent of the province's electricity by 2030, supporting renewable energy job growth across Alberta. A recent supply chain study of the solar electricity sector in Alberta by Solas Energy Consulting Inc. found a potential of $4.1 billion in market value and a labour force rising to 10,000 in 2030.

Maine Hydropower Transmission Line revived by high court after referendum challenge, advancing NECEC, Hydro-Quebec supply, Central Maine Power partnership, clean energy integration, grid reliability, and lower rates across New England pending land-lease ruling.

Key Points

A court-revived NECEC line delivering 1,200 MW of Hydro-Quebec hydropower via CMP to strengthen the New England grid.

✅ Maine high court deems retroactive referendum unconstitutional

✅ Pending state land lease case may affect final route

✅ Project could lower rates and cut emissions in New England

Maine's highest court on Tuesday breathed new life into a $1-billion US transmission line that aims to serve as conduit for Canadian hydropower, after construction starts drew scrutiny, ruling that a statewide vote rebuking the project was unconstitutional.

The Supreme Judicial Court ruled that the retroactive nature of the referendum last year violated the project developer's constitutional rights, sending it back to a lower court for further proceedings.

The court did not rule in a separate case that focuses on a lease for a 1.6-kilometre portion of the proposed power line that crosses state land.

Central Maine Power's parent company and Hydro-Québec teamed up on the project that would supply up to 1,200 megawatts of Canadian hydropower, amid the ongoing Maine-Quebec corridor debate in the region. That's enough electricity for one million homes.

Most of the proposed 233-kilometre power transmission line would be built along existing corridors, but a new 85-kilometre section was needed to reach the Canadian border, echoing debates around the Northern Pass clash in New Hampshire.

Workers were already clearing trees and setting poles when the governor asked for work to be suspended after the referendum in November 2021, mirroring New Hampshire's earlier rejection of a Quebec-Massachusetts proposal that rerouted regional plans. The Maine Department of Environmental Protection later suspended its permit, but that could be reversed depending on the outcome of legal proceedings.

The high court was asked to weigh in on two separate lawsuits. Developers sought to declare the referendum unconstitutional while another lawsuit focused on a lease allowing transmission lines to cross a short segment of state-owned land.

Supporters say bold projects such as this one, funded by ratepayers in Massachusetts, are necessary to battle climate change and introduce additional electricity into a region that's heavily reliant on natural gas, which can cause spikes in energy costs, as seen with Nova Scotia rate increases recently across the Atlantic region.

Critics say the project's environmental benefits are overstated — and that it would harm the woodlands in western Maine.

It was the second time the Supreme Judicial Court was asked to weigh in on a referendum aimed at killing the project. The first referendum proposal never made it onto the ballot after the court raised constitutional concerns.

Although the project is funded by Massachusetts ratepayers, the introduction of so much electricity to the grid would serve to stabilize or reduce electricity rates for all consumers, proponents contend, even as Manitoba Hydro rate hikes face opposition elsewhere.

The referendum on the project was the costliest in Maine history, topping $90 million US and underscoring deep divisions.

The high-stakes campaign put environmental and conservation groups at odds, and pitted utilities backing the project, amid the Hydro One-Avista backlash, against operators of fossil fuel-powered plants that stand to lose money.

SOO Green Underground Transmission Line proposes an HVDC corridor buried along Canadian Pacific railroad rights-of-way to deliver Iowa wind energy to Chicago, enhance grid interconnection, and reduce landowner disruption from new overhead lines.

Key Points

A proposed HVDC project burying lines along a railroad to move Iowa wind power to Chicago and link two grids.

✅ HVDC link from Mason City, IA, to Plano, IL

✅ Buried in Canadian Pacific railroad right-of-way

✅ Connects MISO and PJM grids for renewable exchange

The company behind a proposed underground transmission line that would carry electricity generated mostly by wind turbines in Iowa to the Chicago area said Monday that the $2.5 billion project could be operational in 2024 if regulators approve it, reflecting federal transmission funding trends seen recently.

Direct Connect Development Co. said it has lined up three major investors to back the project. It plans to bury the transmission line in land that runs along existing Canadian Pacific railroad tracks, hopefully reducing the disruption to landowners. It's not unusual for pipelines or fiber optic lines to be buried along railroad tracks in the land the railroad controls.

CEO Trey Ward said he "believes that the SOO Green project will set the standard regarding how transmission lines are developed and constructed in the U.S."

A similar proposal from a different company for an overhead transmission line was withdrawn in 2016 after landowners raised concerns, even as projects like the Great Northern Transmission Line advanced in the region. That $2 billion Rock Island Clean Line was supposed to run from northwest Iowa into Illinois.

The new proposed line, which was first announced in 2017, would run from Mason City, Iowa, to Plano, Ill., a trend echoed by Canadian hydropower to New York projects. The investors announced Monday were Copenhagen Infrastructure Partners, Jingoli Power and Siemens Financial Services.

The underground line would also connect two different regional power operating grids, as seen with U.S.-Canada cross-border transmission approvals in recent years, which would allow the transfer of renewable energy back and forth between customers and producers in the two regions.

More than 36 percent of Iowa's electricity comes from wind turbines across the state.

Jingoli Power CEO Karl Miller said the line would improve the reliability of regional power operators and benefit utilities and corporate customers in Chicago, even amid debates such as Hydro-Quebec line opposition in the Northeast.
