Coal's future not in Carolinas

Ottawa Sewage Energy Exchange System uses wastewater heat recovery and efficient heat pumps to deliver renewable district energy, zero carbon heating and cooling, cutting greenhouse gas emissions at LeBreton Flats and scaling urban developments.

Key Points

A district energy system recovering wastewater heat via pumps to deliver zero carbon heating and cooling.

✅ Delivers 9 MW heating and cooling for 2.4M sq ft at LeBreton Flats

✅ Cuts 5,066 tonnes CO2e each year, reducing greenhouse gases

✅ Powers Odenak zero carbon housing via district energy

Ottawa is embarking on a groundbreaking initiative to harness the latent thermal energy within its wastewater system, in tandem with advances in energy storage in Ontario that strengthen grid resilience, marking a significant stride toward sustainable urban development. The Sewage Energy Exchange System (SEES) project, a collaborative effort led by the LeBreton Community Utility Partnership—which includes Envari Holding Inc. (a subsidiary of Hydro Ottawa) and Theia Partners—aims to revolutionize how the city powers its buildings.

Harnessing Wastewater for Sustainable Energy

The SEES will utilize advanced heat pump technology to extract thermal energy from the city's wastewater infrastructure, providing both heating and cooling to buildings within the LeBreton Flats redevelopment. This innovative approach eliminates the need for fossil fuels, aligning with Ottawa's commitment to reducing greenhouse gas emissions and promoting clean energy solutions across the province, including the Hydrogen Innovation Fund that supports new low-carbon pathways.

The system operates by diverting sewage from the municipal collection network into an external well, where it undergoes filtration to remove large solids. The filtered water is then passed through a heat exchanger, transferring thermal energy to the building's heating and cooling systems. After the energy is extracted, the treated water is safely returned to the city's sewer system.

Environmental and Economic Impact

Once fully implemented, the SEES is projected to deliver over 9 megawatts of heating and cooling capacity, servicing approximately 2.4 million square feet of development. This capacity is expected to reduce greenhouse gas emissions by approximately 5,066 tonnes annually—equivalent to the electricity consumption of over 3,300 homes for a year. Such reductions are pivotal in helping Ottawa meet its ambitious goal of achieving a 96% reduction in community-wide greenhouse gas emissions by 2040, as outlined in its Climate Change Master Plan and Energy Evolution strategy, and they align with Ontario's plan to rely on battery storage to meet rising demand across the grid.

Integration with the Odenak Development

The first phase of the SEES will support the Odenak development, a mixed-use project comprising two high-rise residential buildings. This development is poised to be Canada's largest residential zero-carbon project, echoing calls for Northern Ontario grid sustainability from community groups, featuring 601 housing units, with 41% designated as affordable housing. The integration of the SEES will ensure that Odenak operates entirely on renewable energy, setting a benchmark for future urban developments.

Broader Implications and Future Expansion

The SEES project is not just a localized initiative; it represents a scalable model for sustainable urban energy solutions that aligns with green energy investments in British Columbia and other jurisdictions. The LeBreton Community Utility Partnership is in discussions with the National Capital Commission to explore extending the SEES network to additional parcels within the LeBreton Flats redevelopment. Expanding the system could lead to economies of scale, further reducing costs and enhancing the environmental benefits.

Ottawa's venture into wastewater-based energy systems places it at the forefront of a growing trend in North America. Cities like Toronto and Vancouver have initiated similar projects, while related pilots such as the EV-to-grid pilot in Nova Scotia highlight complementary approaches, and European counterparts have long utilized sewage heat recovery systems. Ottawa's adoption of this technology underscores its commitment to innovation and sustainability in urban planning.

The SEES project at LeBreton Flats exemplifies how cities can repurpose existing infrastructure to create sustainable, low-carbon energy solutions. By transforming wastewater into a valuable energy resource, Ottawa is setting a precedent for environmentally responsible urban development. As the city moves forward with this initiative, it not only addresses immediate energy needs but also contributes to a cleaner, more sustainable future for its residents, even as the province accelerates Ontario's energy storage push to maintain reliability.

Nova Scotia Power Active Demand Control Tariff lets the utility direct Port Hawkesbury Paper load, enabling demand response, efficiency, and industrial electricity rates, while regulators assess impacts on ratepayers, grid reliability, mill viability, and savings.

Key Points

A four-year tariff letting the utility control the mill load for demand response, efficiency, and lower costs.

✅ Utility can increase or reduce daily consumption at the mill

✅ Projected savings of $10M annually for other ratepayers to 2023

✅ Regulators reviewing cost allocation, monitoring, and viability

Nova Scotia Power is scheduled to appear before government regulators Tuesday morning seeking approval for a unique discount rate for its largest customer.

Under the four-year plan, Nova Scotia Power would control the supply of electricity to Port Hawkesbury Paper, a move referenced in a grid operations report that urges changes, with the right to direct the company to increase or reduce daily consumption throughout the year.

The rate proposal is supported by the mill, which says it needs to lower its power bill to keep its operation viable.

The rate went into effect on Jan. 1 on a temporary basis, pending the outcome of a hearing this week before the Nova Scotia Utility and Review Board, amid broader calls for an independent body to lead electricity planning.

The mill accounts for 10 per cent of the provincial electricity load, even as a neighbouring utility pursues more Quebec power for the region, producing glossy paper used in magazines and catalogs.

Nova Scotia Power says controlling how much electricity the mill uses — and when — will allow it to operate the system much more efficiently, as it expands biomass generation initiatives, saving other customers $10 million a year until the rate expires in 2023.

Ceding control 'not an easy decision'
In its opening statement that was filed in advance, Port Hawkesbury Paper said ceding the control of its electrical supply to Nova Scotia Power was "not an easy decision" to make, but the company is confident the arrangement will work.

In September 2019, Nova Scotia Power and the mill jointly applied for an "extra large active demand control tariff," which would provide electricity to the mill for about $61 per megawatt hour, well below the full cost of generating the electricity.

The utility said "fully allocating costs" would result in "prices in excess of $80/MWh ... and [would] not [be] financially viable for the mill."

In its statement, Port Hawkesbury Paper said since the initial filing "there have been greater near term declines in market demand and pricing for PHP's product than was forecast at that time, continuing to put pressure on our business and further highlighting the need to maintain the balance provided for in the new tariff."

Consumer advocate sees 'advantage,' but will challenge
Bill Mahody represents Nova Scotia Power's 400,000 residential customers before the review board. He wants proof the mill will pay enough toward the cost of generating the electricity it uses, amid concerns over biomass use in the province today.

"We filed evidence, as have others involved in the proceeding, that would call into question whether or not the rate design is capturing all of those costs and that will be a significant issue before the board," Mahody said.

Still, he sees value in the proposal.

"This proposed rate gives Nova Scotia Power the ability to control that sizable Port Hawkesbury Paper load to the advantage of other ratepayers, as the province pursues more wind and solar projects, because Nova Scotia Power would be reducing the costs that other ratepayers are going to face," he said.

Mahody is also calling for a mechanism to monitor whether the mill's position actually improves to the point where it could pay higher rates.

"An awful lot can change during a four-year period, with new tidal power projects underway, and I think the board ought to have the ability to check in on this and make sure that their preferential rate continues to be justified," he said.

Major employer
Port Hawkesbury Paper, owned by Stern Partners in Vancouver, has received discounted power rates since it bought the idled mill in 2012. But the "load retention tariff" as it was called, expired at the end of 2019.

Regulators have accepted Nova Scotia Power's argument that it would cost other customers more if the mill ceased to operate.

The mill said it spends between $235 million and $265 million annually, employing 330 people directly and supporting 500 other jobs indirectly.

The Nova Scotia government pledged $124 million in financial assistance as part of the reopening in 2012.

New York Utility Disconnection Ban protects residents during state emergencies, covering electric, gas, water, telecommunications, cable, and internet services, with penalties for noncompliance and options like deferred payment agreements and consumer protections.

Key Points

A proposed law barring shutoffs in state emergencies across electric, gas, water, telecom, cable, and internet.

✅ Applies during declared state and local emergencies statewide.

✅ Covers electric, gas, water, telecom, cable, and internet services.

✅ Noncompliance triggers penalties; payment plans required for arrears.

Governor Andrew M. Cuomo has announced a proposal to prohibit utility disconnections in regions that are under a state of emergency, addressing the energy insecurity many households face, as part of the 2021 State of the State. The Governor will propose legislation that will apply to electric, gas, water, telecommunications, cable and internet services. Utilities that fail to comply will be subject to penalties.

“In a year in which we dealt with an unprecedented pandemic, ferocious storms added insult to injury by knocking out power for hundreds of thousands of New Yorkers,” Governor Cuomo said. “Utility companies provide essential services, and we need to make sure they continue to provide them, rain or shine. That’s why we’re proposing legislation to make sure that New Yorkers, especially those living in regions under states of emergency, have access to these critical services to provide for themselves and their families.”

Governor Cuomo has taken a series of actions to protect New Yorkers’ access to utilities during the COVID-19 pandemic, including a suspension of shut-offs in New York and New Jersey, among other measures. Last year, the Governor signed legislation extending a moratorium that prevents utility companies from disconnecting utilities to residential households that are struggling with their bills due to the COVID-19 pandemic, a move mirrored by reconnection efforts in Ontario by Hydro One. Utility companies must instead offer these individuals a deferred payment agreement on any past-due balance. 

On November 19, Governor Cuomo announced that Con Edison now faces $25 million in penalties and possible license revocation from the New York State Public Service Commission, amid a broader review of retail energy markets by state regulators, following an investigation into the utility’s failed response during large-scale power outages in Manhattan and Brooklyn in July 2019. On November 2, Governor Cuomo announced that more than $328 million in home heating aid is now available, similar to Ontario bill support during the pandemic, for low- and middle-income New Yorkers who need assistance keeping their homes warm during the coming winter season.

The Governor has previously enacted some of the strongest and most progressive consumer protection and assistance programs in the country, including smart streetlights in Syracuse that reduce energy costs, and other initiatives. Governor Cuomo established New York’s energy affordability policy in 2016, as states pursue renewable energy ambitions that can affect rates, underscoring the need for affordability. The policy extended energy bill support to more than 152,000 additional New York families, ensuring that more than 920,000 New York families spend no more than 6 percent of their income on energy bills. Through this program, New York commits more than $238 million annually helping to keep the lights and heat on for our most vulnerable New Yorkers, while actively striving to expand coverage to additional families.

Nunavut electricity rate increase sees QEC raise domestic electricity rates 6.6% over two years, affecting customer rates, base rates, subsidies, and kWh overage charges across communities, with public housing exempt and territory-wide pricing denied.

Key Points

A 6.6% QEC hike over 2018-2019, affecting customer rates, subsidies, and kWh overage; public housing remains exempt.

✅ 3.3% on May 1, 2018; 3.3% on Apr 1, 2019

✅ Subsidy caps: 1,000 kWh Oct-Mar; 700 kWh Apr-Sep

✅ Territory-wide base rate denied; public housing exempt

Ahead of the Nunavut government's approval of the general rate increase for the Qulliq Energy Corporation, many Nunavummiut wondered how the change would impact their electricity bills.

QEC's request for a 6.6-per-cent increase was approved by the government last week. The increase will be spread out over two years, a pattern similar to BC Hydro's two-year rate plan, with the first increase (3.3 per cent) effective May 1, 2018. The remaining 3.3 per cent will be applied on April 1, 2019.

Public housing units, however, are exempt from the government's increase altogether.

The power corporation also asked for a territory-wide rate, so every community would pay the same base rate (we'll go over specific terms in a minute if you're not familiar with them). But that request was denied, even as Manitoba Hydro scaled back increases next year, and QEC will now take the next two years reassessing each community's base rate.

#google#

So, what does this mean for your home's power bill? Well, there's a few things you need to know, which we'll get to in a second.

But in essence, as long as you don't go over the government-subsidized monthly electricity usage limit, you're paying an extra 3.61 cents per kilowatt hour (kWh).

To be clear, we're talking about non-government domestic rates — basically, private homeowners — and those living in a government-owned unit but pay for their own power.

The basics

First, some quick terminology. The "base rate" term we're going to use (and used above) in this story refers to the community rate. As in, what QEC charges customers in every community. The "customer rate" is the rate customers actually pay, after the government's subsidy.

The first thing you need to know is everyone in Nunavut starts off by paying the same customer rate, unlike jurisdictions using a price cap to limit spikes.

That's because the government subsidizes electricity costs, and that subsidy is different in every community, because the base rate is different.

For example, Iqaluit's new base rate after the 3.3 per cent increase (remember, the 6.6 per cent is being applied over two years) is 56.69 cents per kWh, while Kugaaruk's base rate rose to 112.34 cents per kWh. Those, by the way, are the territory's lowest and highest respective base rates.

However, customers in both Iqaluit and Kugaaruk will each now pay 28.35 cents per kWh because, remember, the government subsidizes the base rates in every community.

Now, remember earlier we mentioned a "government-subsidized monthly electricity usage limit?" That's where customers in various communities start to pay different amounts.

As simply as we can explain it, the government will only cover so much electricity usage in a month, in every household.

Between October and March, the government will subsidize the first 1,000 kilowatt hours, and only 700 kilowatt hours from April to September. QEC says the average Nunavut home will use about 500 kilowatt hours every month over the course of a year.

But if your household goes over that limit, you're at the mercy of your community's base rate for any extra electricity you use. Homes in Kugaaruk in December, for instance, will have to pay that 122.34 cents for every extra kilowatt hour it uses, while homes in Iqaluit only have to pay 56.69 cents per kWh for its extra electricity.

That's where many Nunavummiut have criticized the current rate structure, because smaller communities are paying more for their extra costs than larger communities.

QEC had hoped — as it had asked for — to change the structure so every community pays the same base rate. So regardless of if people go over their electricity usage limits for the government subsidy, everyone would pay the same overage rates.

But the government denied that request.

New rate is actually lower

The one thing we should highlight, however, is the new rate after the increase is actually lower than what customers were paying in 2014.

For the past seven months, customers have been getting power from QEC at a discount, whereas Newfoundland customers began paying for Muskrat Falls during the same period, to different effect.

That's because when QEC sets its rates, it does so based on global oil price forecasts. Since 2014, the price of oil worldwide has slumped, and so QEC was able to purchase it at less than it had anticipated.

When that happens, and QEC makes more than $1 million within a six month period thanks to the lower oil prices, it refunds the excess profits back to customers through a discount on electricity base rates — a mechanism similar to a lump-sum credit used elsewhere — the government subsidy, however, doesn't change so the savings are passed on directly to customers.

Now, the 6.6 per cent increase to electricity rates, is actually being applied to the discounted base rate from the last seven months.

So again, while customers are paying more than they have been for the last seven months, it's lower than what they were paying in 2014.

Lastly, to be clear, all the figures used in this story are only for domestic non-government rates. Commercial rates and changes have not been explored in this story, given the differences in subsidy and rate application.

Great British Energy could cut UK electricity costs via public ownership, investing in clean energy like wind, solar, tidal, and nuclear, curbing windfall profits, stabilizing bills, and reinvesting returns through a state-backed generator.

Key Points

A proposed state-backed UK generator investing in clean power to cut costs and return gains to taxpayers.

✅ Publicly owned investment in wind, solar, tidal, and nuclear

✅ Cuts electricity bills by reducing generators' windfall profits

✅ Funded via bonds or asset buyouts; non-profit operations

A publicly owned electricity generation firm could save Britons nearly £21bn a year, according to new analysis that bolsters Labour’s case to launch a national energy company if the party gains power.

Thinktank Common Wealth has calculated that the cost of generating electricity to power homes and businesses could be reduced by £20.8bn or £252 per household a year under state ownership, according to a report seen by the Guardian.

The Labour leader, Keir Starmer, has committed to creating “a publicly owned national champion in clean energy” named Great British Energy.

Starmer is yet to lay out the exact structure of the mooted company, although he has said it would not involve nationalising existing assets, or become involved in the transmission grid or retail supply of energy.

Starmer instead hopes to create a state-backed entity that would invest in clean energy – wind, solar, tidal, nuclear, large-scale storage and other emerging technologies – creating jobs and ensuring windfalls from the growth in low carbon power feed back to the government.

The Common Wealth report, which analysed scenarios for reforming the electricity market, said that a huge saving on electricity costs could be made by buying out assets such as wind, solar and biomass generators on older contracts and running them on a non-profit basis. Funding the measure could require a government bond issuance, or some form of compulsory purchase process.

Last year the government attempted to get companies operating low carbon generators, including nuclear power plants, on older contracts to switch to contracts for difference (CfD), allowing any outsized profits to flow back to taxpayers. However, the government later decided to tax eligible firms through the electricity generator levy instead.

The Common Wealth study concluded that a publicly owned low carbon energy generator would best deliver on Britain’s climate and economic goals, would eliminate windfall profits made by generators and would cut household bills significantly.

MPs and campaigners have argued that Britain’s energy companies should be nationalised since the energy crisis, even as coal-free records have multiplied and renewables still need more support, which has resulted in North Sea oil and gas producers and electricity generators making windfall profits, and a string of retail suppliers collapsing, costing taxpayers billions. Detractors of nationalisation in energy argue it can stifle innovation and expose taxpayers to huge financial risks.

Common Wealth pointed out that more than 40% of the UK’s offshore wind generation capacity was publicly owned by overseas national entities, meaning the benefits of high electricity prices linked to the war in Ukraine had flowed back to other governments.

The study found the publicly owned generator model would create more savings than other options, including a drive for voluntary CfDs; splitting the generation market between low carbon and fossil fuel sources at a time when wind and solar have outproduced nuclear, and a “single buyer model” with nationalised retail suppliers.

Romania Ends CGN Cernavoda Nuclear Deal, as Nuclearelectrica moves to terminate negotiations on reactors 3 and 4, citing the EU Green Deal, US partnership, NATO, and a shift to alternative nuclear capacity options.

Key Points

Romania orders Nuclearelectrica to end CGN talks on Cernavoda units 3-4 and pursue alternative nuclear options.

✅ Negotiations on Cernavoda units 3-4 to be formally terminated

✅ EU Green Deal and US partnership cited over security concerns

✅ Board to draft strategies for new domestic nuclear capacity

Romania's government has mandated the managing board of local nuclear power producer Nuclearelectrica to initiate procedures for terminating negotiations with China General Nuclear Power Group (CGN) on building two new reactors at the Cernavoda nuclear power plant, where IAEA safety reports continue to shape operations.

The government also mandated the managing board to analyse and draw up strategic options on the construction of new electricity generation capacities from nuclear sources, as other countries such as India take steps to get nuclear back on track in response to demand.

The company will negotiate the termination of the agreement signed in 2015 for developing and operating units 3 and 4 at Cernavoda, even as Germany turns away from nuclear within the European landscape. 

At the end of last month, Economy Minister Virgil Popescu said that the collaboration with the Chinese company couldn't continue as it has yielded no results in seven years, despite China's nuclear program expanding steadily elsewhere.

"We have a strategic partnership with the US, and we hold on to it, we respect our partners. We are members of the EU and Nato, even as Germany's final reactor closures unfold in Europe. Aside from that, I think that seven years since this collaboration with the Chinese company began is enough to realise that we can't move on," Popescu said at that time.

Liberal Prime Minister Ludovic Orban announced in January that the government would exit the deal with its Chinese partner. He invoked the European Union's Green Deal rather than security issues or cost concerns circulated previously as the main reason behind a potential end of the deal with CGN to expand Romania's only nuclear power plant, amid concerns that Europe is losing nuclear power when it needs energy.

In August last year, the US included CGN on a blacklist for allegedly trying to get nuclear technology from the US to be used for military purposes in China, even as nuclear cooperation with Cambodia expands in the region.
