AECL Signs Memorandum of Understanding with China and Argentina for CANDU Projects

Mexico Energy Reform Defeat underscores opposition unity as CFE-first rules, state regulators, and lithium nationalization falter amid USMCA concerns, investment risks, and clean energy transition impacts in Congress over power generation policy.

Key Points

The failed push to expand CFE control, flagged for USMCA risks, higher costs, regulator shifts, and slower clean energy transition.

✅ Bill to mandate 54% CFE generation and priority dispatch failed.

✅ Opposition cited USMCA breaches, higher prices, slower clean energy.

✅ Lithium nationalization to return via separate legislation.

Mexican President Andres Manuel Lopez Obrador's plan to increase state control of power generation was defeated in parliament on Sunday, as opposition parties united in the face of a bill they said would hurt investment and breach international obligations, concerns mirrored by rulings such as the Florida court on electricity monopolies that scrutinize market concentration.

His National Regeneration Movement (MORENA) and its allies fell nearly 60 votes short of the two-thirds majority needed in the 500-seat lower house of Congress, mustering just 275 votes after a raucous session that lasted more than 12 hours.

Seeking to roll back previous constitutional reforms that liberalized the electricity market, Lopez Obrador's proposed changes would have done away with a requirement that state-owned Comision Federal de Electricidad (CFE) sell the cheapest electricity first, a move reminiscent of debates when energy groups warned on pricing changes under federal proposals, allowing it to sell its own electricity ahead of other power companies.

Under the bill, the CFE would also have been set to generate a minimum of 54% of the country's total electricity, and energy regulation would have been shifted from independent bodies to state regulators, paralleling concerns raised when a Calgary retailer opposed a market overhaul over regulatory impacts.

The contentious proposals faced much criticism from business groups and the United States, Mexico's top trade partner as well as other allies who argued it would violate the regional trade deal, the United States-Mexico-Canada Agreement (USMCA), even as the USA looks to Canada for green power to deepen cross-border energy ties.

Lopez Obrador had argued the bill would have protected consumers and made the country more energy independent, echoing how Texas weighs market reforms to avoid blackouts to bolster reliability, saying the legislation was vital to his plans to "transform" Mexico.

Although the odds were against his party, he came into the vote seeking to leverage his victory in last weekend's referendum on his leadership.

Speaking ahead of the vote, Jorge Alvarez Maynez, a lawmaker from the opposition Citizens' Movement party, said the proposals, if enacted, would damage Mexico, pointing to experiences like the Texas electricity market bailout after a severe winter storm as cautionary examples.

"There isn't a specialist, academic, environmentalist or activist with a smidgen of doubt - this bill would increase electricity prices, slow the transition to (clean) energy in our country and violate international agreements," he added.

Supporters of clean-energy goals noted that subnational shifts, such as the New Mexico 100% clean electricity bill can illustrate alternative pathways to reform.

The bill also contained a provision to nationalize lithium resources.

Lopez Obrador said this week that if the bill was defeated, he would send another bill to Congress on Monday aiming to have at least the lithium portion of the proposed legislation passed.

BC-Alberta Electricity Restrictions spotlight interprovincial energy tensions, limiting power exports and affecting grid reliability, energy sharing, and climate goals, while raising questions about federal-provincial coordination, smart grids, and storage investments.

Key Points

Policies limiting Alberta's power exports to provinces like BC, prioritizing local demand and affecting grid reliability.

✅ Prioritizes Alberta load over interprovincial power exports

✅ Risks to BC peak demand support and outage resilience

✅ Pressures for federal-provincial coordination and smart-grid investment

In a move that underscores the complexities of Canada's interprovincial energy relationships, the government of British Columbia (B.C.) has formally expressed concerns over recent electricity restrictions imposed by Alberta after it suspended electricity purchase talks with B.C., amid ongoing regional coordination challenges.

Background: Alberta's Electricity Restrictions

Alberta, traditionally reliant on coal and natural gas for electricity generation, has been undergoing a transition towards more sustainable energy sources as it pursues a path to clean electricity in the province.

In response, Alberta introduced restrictions on electricity exports, aiming to prioritize local consumption and stabilize its energy market and has proposed electricity market changes to address structural issues.

B.C.'s Position: Ensuring Energy Reliability and Cooperation

British Columbia, with its diverse energy portfolio and commitment to sustainability, has historically relied on the ability to import electricity from Alberta, especially during periods of high demand or unforeseen shortfalls. The recent restrictions threaten this reliability, prompting B.C.'s government to take action amid an electricity market reshuffle now underway.

B.C. officials have articulated that access to Alberta's electricity is crucial, particularly during outages or times when local generation does not meet demand. The ability to share electricity among provinces ensures a stable and resilient energy system, benefiting consumers and supporting economic activities, including critical minerals operations, that depend on consistent power supply.

Moreover, B.C. has expressed concerns that Alberta's restrictions could set a precedent that might affect future interprovincial energy agreements. Such a precedent could complicate collaborative efforts aimed at achieving national energy goals, including sustainability targets and infrastructure development.

Broader Implications: National Energy Strategy and Climate Goals

The dispute between B.C. and Alberta over electricity exports highlights the absence of a cohesive national energy strategy, as external pressures, including electricity exports at risk, add complexity. While provinces have jurisdiction over their energy resources, the interconnected nature of Canada's power grids necessitates coordinated policies that balance local priorities with national interests.

This situation also underscores the challenges Canada faces in meeting its climate objectives. Transitioning to renewable energy sources requires not only technological innovation but also collaborative policies that ensure energy reliability and affordability across provincial boundaries, as rising electricity prices in Alberta demonstrate.

Potential Path Forward: Dialogue and Negotiation

Addressing the concerns arising from Alberta's electricity restrictions requires a nuanced approach that considers the interests of all stakeholders. Open dialogue between provincial governments is essential to identify solutions that uphold the principles of energy reliability, economic cooperation, and environmental sustainability.

One potential avenue is the establishment of a federal-provincial task force dedicated to energy coordination. Such a body could facilitate discussions on resource sharing, infrastructure investments, and policy harmonization, aiming to prevent conflicts and promote mutual benefits.

Additionally, exploring technological solutions, such as smart grids and energy storage systems, could enhance the flexibility and resilience of interprovincial energy exchanges. Investments in these technologies may reduce the dependency on traditional export mechanisms, offering more dynamic and responsive energy management strategies.

The tensions between British Columbia and Alberta over electricity restrictions serve as a microcosm of the broader challenges facing Canada's energy sector. Balancing provincial autonomy with national interests, ensuring equitable access to energy resources, and achieving climate goals require collaborative efforts and innovative solutions. As the situation develops, stakeholders across the political, economic, and environmental spectrums will need to engage constructively, fostering a Canadian energy landscape that is resilient, sustainable, and inclusive.

Offshore wind power accelerates low-carbon electrification, leveraging floating turbines, high capacity factors, HVDC transmission, and hydrogen production to decarbonize grids, cut CO2, and deliver competitive, reliable renewable energy near demand centers.

Key Points

Offshore wind power uses offshore turbines to deliver low-carbon electricity with high capacity factors and falling costs.

✅ Sea-based wind farms with 40-50% capacity factors

✅ Floating turbines unlock deep-water, far-shore resources

✅ Enables hydrogen production and strengthens grid reliability

The need for affordable low-carbon technologies is greater than ever

Global energy-related CO2 emissions reached a historic high in 2018, driven by an increase in coal use in the power sector. Despite impressive gains for renewables, fossil fuels still account for nearly two-thirds of electricity generation, the same share as 20 years ago. There are signs of a shift, with increasing pledges to decarbonise economies and tackle air pollution, and with World Bank support helping developing countries scale wind, but action needs to accelerate to meet sustainable energy goals. As electrification of the global energy system continues, the need for clean and affordable low-carbon technologies to produce this electricity is more pressing than ever. This World Energy Outlook special report offers a deep dive on a technology that today has a total capacity of 23 GW (80% of it in Europe) and accounts for only 0.3% of global electricity generation, but has the potential to become a mainstay of the world's power supply. The report provides the most comprehensive analysis to date of the global outlook for offshore wind, its contributions to electricity systems and its role in clean energy transitions.

The offshore wind market has been gaining momentum

The global offshore wind market grew nearly 30% per year between 2010 and 2018, benefitting from rapid technology improvements. Over the next five years, about 150 new offshore wind projects are scheduled to be completed around the world, pointing to an increasing role for offshore wind in power supplies. Europe has fostered the technology's development, led by the UK offshore wind sector alongside Germany and Denmark. The United Kingdom and Germany currently have the largest offshore wind capacity in operation, while Denmark produced 15% of its electricity from offshore wind in 2018. China added more capacity than any other country in 2018.

The untapped potential of offshore wind is vast

The best offshore wind sites could supply more than the total amount of electricity consumed worldwide today. And that would involve tapping only the sites close to shores. The IEA initiated a new geospatial analysis for this report to assess offshore wind technical potential country by country. The analysis was based on the latest global weather data on wind speed and quality while factoring in the newest turbine designs. Offshore wind's technical potential is 36 000 TWh per year for installations in water less than 60 metres deep and within 60 km from shore. Global electricity demand is currently 23 000 TWh. Moving further from shore and into deeper waters, floating turbines could unlock enough potential to meet the world's total electricity demand 11 times over in 2040. Our new geospatial analysis indicates that offshore wind alone could meet several times electricity demand in a number of countries, including in Europe, the United States and Japan. The industry is adapting various floating foundation technologies that have already been proven in the oil and gas sector. The first projects are under development and look to prove the feasibility and cost-effectiveness of floating offshore wind technologies.

Offshore wind's attributes are very promising for power systems

New offshore wind projects have capacity factors of 40-50%, as larger turbines and other technology improvements are helping to make the most of available wind resources. At these levels, offshore wind matches the capacity factors of gas- and coal-fired power plants in some regions – though offshore wind is not available at all times. Its capacity factors exceed those of onshore wind and are about double those of solar PV. Offshore wind output varies according to the strength of the wind, but its hourly variability is lower than that of solar PV. Offshore wind typically fluctuates within a narrower band, up to 20% from hour to hour, than solar PV, which varies up to 40%.

Offshore wind's high capacity factors and lower variability make its system value comparable to baseload technologies, placing it in a category of its own – a variable baseload technology. Offshore wind can generate electricity during all hours of the day and tends to produce more electricity in winter months in Europe, the United States and China, as well as during the monsoon season in India. These characteristics mean that offshore wind's system value is generally higher than that of its onshore counterpart and more stable over time than that of solar PV. Offshore wind also contributes to electricity security, with its high availability and seasonality patterns it is able to make a stronger contribution to system needs than other variable renewables. In doing so, offshore wind contributes to reducing CO2 and air pollutant emissions while also lowering the need for investment in dispatchable power plants. Offshore wind also has the advantage of avoiding many land use and social acceptance issues that other variable renewables are facing.

Offshore wind is on track to be a competitive source of electricity

Offshore wind is set to be competitive with fossil fuels within the next decade, as well as with other renewables including solar PV. The cost of offshore wind is declining and is set to fall further. Financing costs account for 35% to 50% of overall generation cost, and supportive policy frameworks are now enabling projects to secure low cost financing in Europe, with zero-subsidy tenders being awarded. Technology costs are also falling. The levelised cost of electricity produced by offshore wind is projected to decline by nearly 60% by 2040. Combined with its relatively high value to the system, this will make offshore wind one of the most competitive sources of electricity. In Europe, recent auctions indicate that offshore wind will soon beat new natural gas-fired capacity on cost and be on a par with solar PV and onshore wind. In China, offshore wind is set to become competitive with new coal-fired capacity around 2030 and be on par with solar PV and onshore wind. In the United States, recent project proposals indicate that offshore wind will soon be an affordable option, even as the 1 GW timeline continues to evolve, with potential to serve demand centres along the country's east coast.

Innovation is delivering deep cost reductions in offshore wind, and transmission costs will become increasingly important. The average upfront cost to build a 1 gigawatt offshore wind project, including transmission, was over $4 billion in 2018, but the cost is set to drop by more than 40% over the next decade. This overall decline is driven by a 60% reduction in the costs of turbines, foundations and their installation. Transmission accounts for around one-quarter of total offshore wind costs today, but its share in total costs is set to increase to about one-half as new projects move further from shore. Innovation in transmission, for example through work to expand the limits of direct current technologies, will be essential to support new projects without raising their overall costs.

Offshore wind is set to become a $1 trillion business

Offshore wind power capacity is set to increase by at least 15-fold worldwide by 2040, becoming a $1 trillion business. Under current investment plans and policies, the global offshore wind market is set to expand by 13% per year, reflecting its growth despite Covid-19 in recent years, passing 20 GW of additions per year by 2030. This will require capital spending of $840 billion over the next two decades, almost matching that for natural gas-fired or coal-fired capacity. Achieving global climate and sustainability goals would require faster growth: capacity additions would need to approach 40 GW per year in the 2030s, pushing cumulative investment to over $1.2 trillion. 

The promising outlook for offshore wind is underpinned by policy support in an increasing number of regions. Several European North Seas countries – including the United Kingdom, Germany, the Netherlands and Denmark – have policy targets supporting offshore wind. Although a relative newcomer to the technology, China is quickly building up its offshore wind industry, aiming to develop a project pipeline of 10 GW by 2020. In the United States, state-level targets and federal incentives are set to kick-start the U.S. offshore wind surge in the coming years. Additionally, policy targets are in place and projects under development in Korea, Japan, Chinese Taipei and Viet Nam.

 The synergies between offshore wind and offshore oil and gas activities provide new market opportunities. Since offshore energy operations share technologies and elements of their supply chains, oil and gas companies started investing in offshore wind projects many years ago. We estimate that about 40% of the full lifetime costs of an offshore wind project, including construction and maintenance, have significant synergies with the offshore oil and gas sector. That translates into a market opportunity of $400 billion or more in Europe and China over the next two decades. The construction of foundations and subsea structures offers potential crossover business, as do practices related to the maintenance and inspection of platforms. In addition to these opportunities, offshore oil and gas platforms require electricity that is often supplied by gas turbines or diesel engines, but that could be provided by nearby wind farms, thereby reducing CO2 emissions, air pollutants and costs.

Offshore wind can accelerate clean energy transitions

Offshore wind can help drive energy transitions by decarbonising electricity and by producing low-carbon fuels. Over the next two decades, its expansion could avoid between 5 billion and 7 billion tonnes of CO2 emissions from the power sector globally, while also reducing air pollution and enhancing energy security by reducing reliance on imported fuels. The European Union is poised to continue leading the wind energy at sea in Europe industry in support of its climate goals: its offshore wind capacity is set to increase by at least fourfold by 2030. This growth puts offshore wind on track to become the European Union's largest source of electricity in the 2040s. Beyond electricity, offshore wind's high capacity factors and falling costs makes it a good match to produce low-carbon hydrogen, a versatile product that could help decarbonise the buildings sector and some of the hardest to abate activities in industry and transport. For example, a 1 gigawatt offshore wind project could produce enough low-carbon hydrogen to heat about 250 000 homes. Rising demand for low-carbon hydrogen could also dramatically increase the market potential for offshore wind. Europe is looking to develop offshore "hubs" for producing electricity and clean hydrogen from offshore wind.

It's not all smooth sailing

Offshore wind faces several challenges that could slow its growth in established and emerging markets, but policy makers and regulators can clear the path ahead. Developing efficient supply chains is crucial for the offshore wind industry to deliver low-cost projects. Doing so is likely to call for multibillion-dollar investments in ever-larger support vessels and construction equipment. Such investment is especially difficult in the face of uncertainty. Governments can facilitate investment of this kind by establishing a long-term vision for offshore wind and by drawing on U.K. policy lessons to define the measures to be taken to help make that vision a reality. Long-term clarity would also enable effective system integration of offshore wind, including system planning to ensure reliability during periods of low wind availability.

The success of offshore wind depends on developing onshore grid infrastructure. Whether the responsibility for developing offshore transmission lies with project developers or transmission system operators, regulations should encourage efficient planning and design practices that support the long-term vision for offshore wind. Those regulations should recognise that the development of onshore grid infrastructure is essential to the efficient integration of power production from offshore wind. Without appropriate grid reinforcements and expansion, there is a risk of large amounts of offshore wind power going unused, and opportunities for further expansion could be stifled. Development could also be slowed by marine planning practices, regulations for awarding development rights and public acceptance issues.

The future of offshore wind looks bright but hinges on the right policies

The outlook for offshore wind is very positive as efforts to decarbonise and reduce local pollution accelerate. While offshore wind provides just 0.3% of global electricity supply today, it has vast potential around the world and an important role to play in the broader energy system. Offshore wind can drive down CO2 emissions and air pollutants from electricity generation. It can also do so in other sectors through the production of clean hydrogen and related fuels. The high system value of offshore wind offers advantages that make a strong case for its role alongside other renewables and low-carbon technologies. Government policies will continue to play a critical role in the future of offshore wind and  the overall pace of clean energy transitions around the world.

Idaho Renewable Energy 2018 saw over 80% in-state utility-scale power from hydropower, wind, solar, biomass, and geothermal, per EIA, with imports declining as Snake River Plain resources and Hells Canyon hydro lead.

Key Points

Idaho produced over 80% in-state power from renewables in 2018, led by hydropower, wind, solar, and biomass.

✅ Hydropower supplies about half of capacity; Hells Canyon leads.

✅ Wind provides nearly 20% of capacity along the Snake River Plain.

✅ Utility-scale solar surged since 2016; biomass and geothermal add output.

More than 80% of Idaho’s in-state utility-scale electricity generation came from renewable resources in 2018, behind only Vermont, according to recently released data from the U.S. Energy Information Administration’s Electric Power Monthly and broader trends showing that solar and wind reached about 10% of U.S. generation in the first half of 2018.

Idaho generated 17.4 million MWh of electricity in 2018, of which 14.2 million MWh came from renewable sources, while nationally January power generation jumped 9.3% year over year according to EIA. Idaho uses a variety of renewable resources to generate electricity:

Hydroelectricity. Idaho ranked seventh in the U.S. in electricity generation from hydropower in 2018. About half of Idaho’s electricity generating capacity is at hydroelectric power plants, and utility actions such as the Idaho Power settlement could influence future resource choices, and seven of the state’s 10 largest power plants (in terms of electricity generation) are hydroelectric facilities. The largest privately owned hydroelectric generating facility in the U.S. is a three-dam complex on the Snake River in Hells Canyon, the deepest river gorge in North America.

Wind. Nearly one-fifth of Idaho’s electricity generating capacity and one-sixth of its generation comes from wind turbines. Idaho has substantial wind energy potential, and nationally the EIA expects solar and wind to be larger sources this summer, although only a small percentage of the state's land area is well-suited for wind development. All of the state’s wind farms are located in the southern half of the state along the Snake River Plain.

Solar. Almost 5% of Idaho’s electricity generating capacity and 3% of its generation come from utility-scale solar facilities, and nationally over half of new capacity in 2023 will be solar according to projections. The state had no utility-scale solar generation as recently as 2015. Between 2016 and 2017, Idaho’s utility-scale capacity doubled and generation increased from 30,000 MWh to more than 450,000 MWh. Idaho’s small-scale solar capacity also doubled since 2017, generating 33,000 MWh in 2018.

Biomass. Biomass-fueled power plants account for about 2% of the state’s utility-scale electricity generating capacity and 3% of its generation, contributing to a broader U.S. shift where 40% of electricity came from non-fossil sources in 2021. Wood waste from the state’s forests is the primary fuel for these plants.

Geothermal. Idaho is one of seven states with utility-scale geothermal electricity generation. Idaho has one 18-MW geothermal facility, located near the state’s southern border with Utah.

EIA says Idaho requires significant electricity imports, totaling about one-third of demand, to meet its electricity needs. However, Idaho’s electricity imports have decreased over time, and Georgia's recent import levels illustrate how regional dynamics can vary. Almost all of these imports are from neighboring states, as electricity imports from Canada accounted for less than 0.1% of Idaho’s total electricity supply in 2017.

Norway Electricity Export Limits weigh hydro reservoirs, energy security, EU-UK interconnectors, and record power prices amid Russia gas cuts; Statnett grid constraints and subsidies debate intensify as reservoir levels fall, threatening winter supply.

Key Points

Rules to curb Norway's power exports when reservoirs are very low, protecting supply security and easing extreme prices.

✅ Triggered by low hydro levels and record day-ahead prices

✅ Considers EU/UK cables, Statnett operations, seasonal thresholds

✅ Aims to secure winter supply and expand subsidies

Norway, one of Europe’s biggest electricity exporters, is considering measures to limit power shipments to prevent domestic shortages amid surging prices, according to local media reports.

The government may propose a rule to limit exports if the water level for Norway’s hydro reservoirs drops to “very low” levels, to ensure security of supply, said Energy Minister Terje Aasland, according NTB newswire. The limit would take account of seasonality and would differ across the about 1,800 hydro reservoirs, he said. 

Russia’s gas supply cuts in retaliation for European sanctions over the war in Ukraine have triggered the continent’s worst energy crisis in decades, with demand surging for cheap Norwegian hydro electricity. Yet the government faces increasing calls from the public and opposition to limit flows abroad. Prices are near record levels in some parts of the Nordic nation as hydro-reservoir levels have plunged in the south after a drier-than-normal spring. 

The government has been under pressure to do something about exports since before April. Flows on the cables are regulated by deals with both the European Union and the UK energy market and Norway can’t simply cut flows. It’s the latest test of European solidarity and a wake-up call for Europe when it comes to energy supplies. Hungary is trying to ban energy exports after it declared an energy emergency.

Back in May, grid operator Statnett SF warned that Norway could face a strained power situation after less snowfall than usual during the winter. At the end of last week, the level of filling in Norwegian hydro reservoirs was 66.5%, compared with a median 74.9% for the corresponding time in 2002-2021, regulator NVE said. Day-ahead electricity prices in southwest Norway soared to a record 423 euros per megawatt-hour late last month, partly due to bottlenecks in the grid limiting supply from the northern regions.

The grid operator has been asked to present by Oct. 1 possible measures that need to be taken to secure supply and infrastructure security ahead of the winter. Statnett operates cables to the UK and Germany aimed at selling surplus electricity and would likely take a financial hit if curbs were introduced. “Operations of these will always follow current laws and regulations,” Irene Meldal, a company spokeswoman, said Friday by email. 

Premier Jonas Gahr Store signaled his minority government will file proposals that also include more subsidies to families and companies and align with Europe’s emergency price measures during August, according to an interview with TV2 on Thursday. Meanwhile, opposition politicians plan to hold an extraordinary parliament meeting to discuss boosting the subsidies.

Aasland will summon the parties’ representatives to a meeting on Monday on the electricity crisis, the Aftenposten newspaper reported on Friday, without citing anyone. He intends to inform the parties about the ongoing work and aims to “avoid rushed decisions” by the parliamentary majority.

Norway Faces Pressure to Curb Power Exports as Prices Surge (1)

The nation gets almost all of its electricity from its vast hydro resources. Historically, it has been able to export a hefty surplus and still have among the lowest prices in Europe.

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.
