Canada Oil and Gas Emissions Cap sets five-year targets to cut sector emissions toward net-zero by 2050, alongside an EV mandate, carbon pricing signals, and support for carbon capture, clean energy jobs, climate policy.

Key Points

A federal policy to regulate and reduce oil and gas emissions via 5-year targets, reaching net-zero by 2050.

✅ Regulated 5-year milestones to cut oil and gas emissions to net-zero by 2050

✅ Interim EV mandate: 50% by 2030; 100% zero-emission sales by 2035

✅ $2B fund for clean energy jobs in oil- and gas-reliant communities

Liberal Leader Justin Trudeau vowed to regulate total emissions from Canada’s oil and gas producers as he laid out his first major climate change promises of the campaign Sunday, a plan that was welcomed by several environmental and climate organizations.

Trudeau said that if re-elected, the Liberals will set out regulated five-year targets for emissions from oil and gas production to get them to net-zero emissions by 2050, a goal that, according to an IEA report will require more electricity, but also create a $2 billion fund to create jobs in oil and gas-reliant communities in Alberta, Saskatchewan and Newfoundland and Labrador.

“Let’s be realistic, over a quarter of Canada’s emissions come from our oil and gas sector. We need the leadership of these industries to decarbonize our country,” Trudeau said.

“That’s why we’ll make sure oil and gas emissions don’t increase and instead go down with achievable milestones,” while ensuring local economies can prosper.“

The Liberals are also introducing an interim electric vehicle mandate, which will require half the cars sold in Canada to be zero-emission by 2030, and because cleaning up electricity is critical to meeting climate pledges, the policy pairs with power-sector decarbonization, ahead of the final mandated target of 100 per cent by 2035.

Trudeau spoke in Cambridge, Ont., where protesters once again made an appearance amid a visible police presence. Officers carried one woman off the property when she refused to leave when asked.

Trudeau alluded to the protesters and their actions, which included sounding sirens and chanting expletives, as he defended his government’s record on climate change including progress in the electricity sector nationally, and touted its new plan.

“Sirens in the background may remind us that this is a climate emergency. That’s why we will move faster and be bolder,” he said.

Canada’s largest oilsands producers have already committed to reaching net zero greenhouse gas emissions by 2050, but the policy proposed Sunday “calls the oil companies’ bluff” by making those goals a legislated requirement, said Keith Stewart, senior energy strategist with Greenpeace Canada.

The new timeline for electric vehicles also “sends a clear signal to auto companies to get cracking (and build them here),” he said on Twitter, even as proposals like a fully renewable grid by 2030 are debated today. “We’d like to see this happen faster but the shift away from voluntary targets to requirements is big.”

Merran Smith, executive director of Clean Energy Canada, a climate program at Simon Fraser University, said clean electricity, clean transportation and “phasing out oil and gas with accountable milestones” must be key priorities over the next decade, aligning with Canada’s race to net-zero and the role of renewable energy.

“Today’s announcement, which checks all of these boxes, is not just good ambition_it’s good policy. Policy that will drive down carbon pollution and drive up clean job growth and economic competitiveness. It is policy that will drive Canada forward with cleaner cars, power Canada with clean electricity, and invest in businesses that will last such as battery manufacturing, electric vehicle manufacturing and low carbon steel,” Smith said in an email.

Michael Bernstein, executive director of the climate policy organization Clean Prosperity, said the promises laid out Sunday offer a “strong boost” to the federal government’s previous climate commitments.

He said the organization prefers market incentives such as carbon pricing, that spur innovation over further regulation. But since the largest oilsands companies have already committed to reaching net-zero emissions, he said the newly unveiled policy could provide some support.

“ First, I would encourage the Liberal Party to release independent modelling showing the types of emissions reductions they expect to achieve with their new package of policies. Second, many policies are referred to in general terms so I hope the Liberal Party will provide further details in the coming days,” he said.

“Finally, the document does not specifically mention carbon capture or carbon dioxide removal technologies but both technologies will be critical to achieve some of the pledges in today’s announcement, especially reaching net-zero emissions in the oil a gas sector.”

NDP Leader Jagmeet Singh painted the announcement as the latest in a string of “empty promises” from the Liberals on climate change, saying Canada has the highest increase in greenhouse gas emissions among all G7 countries, and that provinces like B.C. risk missing 2050 targets as well, he argued.

“Climate targets mean nothing when you don’t act on them. We can’t afford more of Justin Trudeau’s empty words on climate change,” he said in a statement.

The Trudeau Liberals submitted new targets to the United Nations in July, promising that Canada will curb emissions by 40 to 45 per cent from 2005 levels by 2030, building on the net-zero by 2050 plan announced earlier, officials say.

Champlain Hudson Power Express connects Hydro-Québec hydropower to the New York grid via a 1.25 GW high voltage transmission line, enabling renewable energy imports, grid decarbonization, storage synergy, and reduced fossil fuel generation.

Key Points

A 1.25 GW cross-border transmission project delivering Hydro-Québec hydropower to New York City to displace fossil power.

✅ 1.25 GW buried HV line from Quebec to Astoria, Queens

✅ Supports renewable imports and grid decarbonization in NYC

✅ Enables two-way trade and reservoir storage synergy

Last week, Quebec Premier François Legault took to Twitter to celebrate after New York State authorities tentatively approved the first new transmission line in three decades, the Champlain Hudson Power Express, that would connect Quebec’s vast hydroelectric network to the northeastern U.S. grid.

“C’est une immense nouvelle pour l’environnement. De l’énergie fossile sera remplacée par de l’énergie renouvelable,” he tweeted, or translated to English: “This is huge news for the environment. Fossil fuels will be replaced by renewable energy.”

The proposed construction of a 1.25 gigawatt transmission line from southern Quebec to Astoria, Queens, known as the Champlain Hudson Power Express, ties into a longer term strategy by Hydro Québec: in the coming decade, as cities such as New York and Boston look to transition away from fossil fuel-generated electricity and decarbonize their grids, Hydro-Québec sees opportunities to supply them with energy from its vast network of 61 hydroelectric generating stations and other renewable power, as Quebec has closed the door on nuclear power in recent years.

Already, the provincial utility is one of North America’s largest energy producers, generating $2.3 billion in net income in 2020, and planning to increase hydropower capacity over the near term. Hydro-Quebec has said it intends to increase exports and had set a goal of reaching $5.2 billion in net income by 2030, though its forecasts are currently under review.

But just as oil and gas companies have encountered opposition to nearly every new pipeline, Hydro-Québec is finding resistance as it seeks to expand its pathways into major export markets, which are all in the U.S. northeast. Indeed, some fossil fuel companies that would be displaced by Hydro-Québec are fighting to block the construction of its new transmission lines.

“Linear projects — be it a transmission line or a pipeline or highway or whatever — there’s always a certain amount of public opposition,” Gary Sutherland, director of strategic affairs and stakeholder relations for Hydro-Québec, told the Financial Post, “which is a good thing because it makes the project developer ask the right questions.”

While Sutherland said he isn’t expecting opposition to the line into New York, he acknowledged Hydro-Québec also didn’t fully anticipate the opposition encountered with the New England Clean Energy Connect, a 1.2 gigawatt transmission line that would cost an estimated US$950 million and run from Quebec through Maine, eventually connecting to Massachusetts’ grid.

In Maine, natural gas and nuclear energy companies, which stand to lose market share, and also environmentalists, who oppose logging through sensitive habitat, both oppose the project.

In August, Maine’s highest court invalidated a lease for the land where the lines were slated to be built, throwing permits into question. Meanwhile, Calpine Corporation and Vistra Energy Corp., both Texas-based companies that operate natural gas plants in Maine, formed a political action committee called Mainers for Local Power. It has raised nearly US$8 million to fight the transmission line, according to filings with the Maine Ethics Commission.

Neither Calpine nor Vistra could be reached for comment by the time of publication.

“It’s been 30 years since we built a transmission line into the U.S. northeast,” said Sutherland. “In that time we have increased our exports significantly … but we haven’t been able to build out the corresponding transmission to get that energy from point A to point B.”

Indeed, since 2003, Hydro-Québec’s exports outside the province have grown from roughly two terrawatts per year to more than 30 terrawatts, including recent deals with NB Power to move more electricity into New Brunswick. The provincial utility produces around 210 terrawatts annually, but uses less than 178 terrawatts in Quebec.

Linear projects — be it a transmission line or a pipeline or highway or whatever — there’s always a certain amount of public opposition

In Massachusetts, it has signed contracts to supply 9.4 terrawatts annually — an amount roughly equivalent to 8 per cent of the New England region’s total consumption. Meanwhile, in New York, Hydro-Québec is in the final stages of negotiating a 25-year contract to sell 10.4 terawatts — about 20 per cent of New York City’s annual consumption.

In his tweets, Legault described the New York contract as being worth more than $20 billion over 25 years, although Hydro Québec declined to comment on the value because the contract is still under negotiation and needs approval by New York’s Public Services Commission — expected by mid-December.

Both regions are planning to build out solar and wind power to meet their growing clean energy needs and reach ambitious 2030 decarbonization targets. New York has legislated a goal of 70 per cent renewable power by that time, while Massachusetts has called for a 50 per cent reduction in emissions in the same period.

According to a 2020 paper titled “Two Way Trade in Green Electrons,” written by three researchers at the Center for Energy and Environmental Policy Research at the Massachusetts’ Institute for Technology, Quebec’s hydropower, which like fossil fuels can be dispatched, will help cheaply and efficiently decarbonize these grids.

“Today transmission capacity is used to deliver energy south, from Quebec to the northeast,” the researchers wrote, adding, “…in a future low-carbon grid, it is economically optimal to use the transmission to send energy in both directions.”

That is, once new transmission lines and wind and solar power are built, New York and Massachusetts could send excess energy into Quebec where it could be stored in hydroelectric reservoirs until needed.

“This is the future of this northeast region, as New York state and New England are decarbonizing,” said Sutherland. “The only renewable energies they can put on the grid are intermittent, so they’re going to need this backup and right to the north of them, they’ve got Hydro-Québec as backup.”

Hydro-Québec already sells roughly 7 terrawatts of electricity per year into New York on the spot market, but Sutherland says it is constrained by transmission constraints that limit additional deliveries.

And because transmission lines can cost billions of dollars to build, he said Hydro-Québec needs the security of long-term contracts that ensure it will be paid back over time, aligning with its broader $185-billion transition strategy to reduce reliance on fossil fuels.

Sutherland expressed confidence that the Champlain Hudson Power Express project would be constructed by 2025. He noted its partners, Blackstone-backed Transmission Developers, have been working on the project for more than a decade, and have already won support from labour unions, some environmental groups and industry.

The project calls for a barge to move through Lake Champlain and the Hudson River, and dig a trench while unspooling and burying two high voltage cables, each about 10-12 centimetres in diameter. In certain sections of the Hudson River, known to have high concentrations of PCP pollutants, the cable would be buried underground alongside the river.

Texas Electricity Market Bailout proposes securitization bonds and ERCOT-backed fees after Winter Storm Uri, spreading costs via ratepayer charges on power bills to stabilize generators, co-ops, and retailers and avert bankruptcies and investor flight.

Key Points

State plan to securitize storm debts via ERCOT fees, adding bill charges to stabilize Texas power firms.

✅ Securitization bonds finance unpaid ancillary services and energy costs

✅ ERCOT fee spreads Winter Storm Uri debts across ratepayers statewide

✅ Aims to prevent bankruptcies, preserve grid reliability, reassure investors

An approximately $2.5 billion plan to bail out Texas’ distressed electricity market from the financial crisis caused by Winter Storm Uri in February has been approved by the Texas House.

The legislation would impose a fee — likely for the next decade or longer — on electricity companies, which would then get passed on to residential and business customers in their power bills, even as some utilities waived certain fees earlier in the crisis.

House lawmakers sent House Bill 4492 to the Senate on Thursday after a 129-15 vote. A similar bill is advancing in the Senate.

Some of the state’s electricity providers and generators are financially underwater in the aftermath of the February power outages, which left millions without power and killed more than 100 people. Electricity companies had to buy whatever power was available at the maximum rate allowed by Texas regulations — $9,000 per megawatt hour — during the week of the storm (the average price for power in 2020 was $22 per megawatt hour). Natural gas fuel prices also spiked more than 700% during the storm.

Several companies are nearing default on their bills to the Electric Reliability Council of Texas, which manages the Texas power grid that covers most of the state and facilitates financial transactions in it.

Rural electric cooperatives were especially hard hit; Brazos Electric Power Cooperative, which supplies electricity to 1.5 million customers, filed for bankruptcy citing a $1.8 billion debt to ERCOT.

State Rep. Chris Paddie, R-Marshall, the bill’s author, said a second bailout bill will be necessary during the current legislative session for severely distressed electric cooperatives.

“This is a financial crisis, and it’s a big one,” James Schaefer, a senior managing director at Guggenheim Partners, an investment bank, told lawmakers at a House State Affairs Committee hearing in early April. He warned that more bankruptcies would cause higher costs to customers and hurt the state’s image in the eyes of investors.

“You’ve got to free the system,” Schaefer said. “It’s horrible that a bunch of folks have to pay, but it’s a system-wide failure. If you let a bunch of folks crash, it’s not a good look for your state.”

If approved by the Senate and Gov. Greg Abbott, a newly-created Texas Electric Securitization Corp. would use the money raised from the fees for bonds to help pay the companies’ debts, including costs for ancillary services, a financial product that helps ensure power is continuously generated and improve electricity reliability across the grid.

Paddie told his colleagues Wednesday that he could not yet estimate how long the new fee would be imposed, but during committee hearings lawmakers estimated it’s likely to be at least a decade. Several other bills to spread out the costs of the winter storm and consider market reforms are also moving through the Legislature.

ERCOT’s independent market monitor recommended in March that energy sold during that period be repriced at a lower rate, which would have allowed ERCOT to claw back about $4.2 billion in payments to power generators, but the Public Utility Commission declined to do so, even as a court ruling on plant obligations in emergencies drew scrutiny among market participants.

Instead, lawmakers are pushing for bailouts that several energy experts have said is needed, both to ensure distressed companies don’t pass enormous costs on to their customers and to prevent electricity investors and companies from leaving the state if it’s viewed as too risky to continue doing business.

Becky Klein, an energy consultant in Austin and former chair of the Public Utility Commission who played a key role in de-regulating Texas’ electricity market two decades ago, said during a retail electricity panel hosted by Integrate that legislation is necessary to provide “some kind of backstop during a crazy market crisis like this to show the financial market that we’re willing to provide some relief.”

Still, some lawmakers are concerned with how they will win public support, including potential voter-approved funding measures, for bills to bail out the state’s electricity market.

“I have to go back to Laredo and say, ‘I know you didn’t have electricity for several days, but now I’m going to make you pay a little more for the next 20 years,’” state Rep. Richard Peña Raymond, D-Laredo, said during an early April discussion on the plan in the House State Affairs Committee. He said he voted for the bill because it’s in the best interest of the state.

Paddie, during the same committee hearing, acknowledged that “none of us want to increase fees or taxes.” However, he said, “We have to deal with the reality set before us.”

By inviting bids from renewable energy sources and innovative technologies, the government aims to support its climate action plan and contribute to the province’s carbon reduction targets.

Cost-effectiveness is also a central focus of the procurement process. By creating a competitive environment, the government anticipates that energy providers will strive to offer more attractive pricing structures and fair electricity cost allocation practices for ratepayers. This, in turn, could lead to lower energy costs for consumers and businesses, fostering economic growth and improving affordability.

The Competitive Landscape

The competitive energy procurement process will be structured to encourage participation from a wide range of energy providers. This includes not only established companies but also emerging players and startups with innovative technologies. By fostering a diverse pool of bidders, the government aims to ensure that all viable options are considered, ultimately leading to a more robust and adaptable energy system.

Additionally, the process will likely involve various stages of evaluation, including technical assessments, financial analyses, and environmental impact reviews. This thorough evaluation will help ensure that selected projects meet the highest standards of performance and sustainability.

Implications for Stakeholders

The implications of this procurement process extend beyond just energy providers and consumers. Local communities, businesses, and environmental organizations will all play a role in shaping the outcomes. For communities, this initiative could mean new job opportunities and economic development, particularly in regions where new energy projects are developed. For businesses, the potential for lower energy costs and access to innovative energy solutions, including demand-response initiatives like the Peak Perks program, could drive growth and competitiveness.

Environmental organizations will be keenly watching the process to ensure that it aligns with broader sustainability goals. The inclusion of renewable energy sources and advanced technologies will be a critical factor in evaluating the success of the initiative in meeting Ontario’s climate objectives.

Looking Ahead

As Ontario embarks on this unprecedented energy procurement journey, the outcomes will be closely watched by various stakeholders. The success of this initiative will depend on the quality and diversity of the bids received, the efficiency of the evaluation process, and the ability to integrate new energy sources into the existing grid, while advancing energy independence where feasible.

In conclusion, Ontario’s launch of the largest competitive energy procurement process in its history is a landmark event that holds promise for a more reliable, sustainable, and cost-effective energy future. By embracing competition and innovation, the province is setting a new standard for energy procurement that could serve as a model for other regions seeking to modernize their energy systems. The coming months will be crucial in determining how this bold initiative will shape Ontario’s energy landscape for years to come.

Pacific Northwest Transmission Bottleneck slows clean energy progress as BPA's aging grid constrains renewable interconnections, delaying wind, solar, and data center growth; decarbonization targets depend on transmission upgrades, new substations, and policy reform.

Key Points

An interconnection and capacity shortfall on BPA's aging grid that delays renewables and impedes clean energy goals.

✅ BPA approvals lag: 1 of 469 projects since 2015.

✅ Yakama solar waits for substation upgrades until 2027.

✅ Data centers and decarbonization targets face grid constraints.

Oregon and Washington have set ambitious targets to decarbonize their power sectors, aiming for 100% clean electricity in the coming decades. However, a significant obstacle stands in the way: the region's aging and overburdened transmission grid, underscoring why 100% renewables remain elusive even as momentum builds.

The Grid Bottleneck

The BPA operates a transmission system that is nearly a century old in some areas, and its capacity has not expanded sufficiently to accommodate the influx of renewable energy projects, reflecting stalled grid spending in many parts of the U.S., according to recent analyses. Since 2015, 469 large renewable projects have applied to connect to the BPA's grid; however, only one has been approved—a stark contrast to other regions in the country. This bottleneck has left numerous wind and solar projects in limbo, unable to deliver power to the grid.

One notable example is the Yakama Nation's solar project. Despite receiving a $32 million federal grant under the bipartisan infrastructure law as part of a broader grid overhaul for renewables, the tribe faces significant delays. The BPA estimates that it will take until 2027 to complete the necessary upgrades to the transmission system, including a new substation, before the solar array can be connected. This timeline poses a risk of losing federal funding if the project isn't operational by 2031.

Economic and Environmental Implications

The slow pace of grid expansion has broader implications for the region's economy and environmental goals. Data centers and other energy-intensive industries are increasingly drawn to the Pacific Northwest due to its clean energy potential, while interregional projects like the Wyoming-to-California wind link illustrate how transmission access can unlock supply. However, without adequate infrastructure, these industries may seek alternatives elsewhere. Additionally, the inability to integrate renewable energy efficiently hampers efforts to reduce greenhouse gas emissions and combat climate change.

Policy Challenges and Legislative Efforts

Efforts to address the grid limitations through state-level initiatives have faced challenges, even as a federal rule to boost transmission advances nationally. In 2025, both Oregon and Washington considered legislation to establish state bonding authorities aimed at financing transmission upgrades. However, these bills failed to pass, leaving the BPA as the primary entity responsible for grid expansion. The BPA's unique structure—operating as a self-funded federal agency without direct state oversight—has made it difficult for regional leaders to influence its decision-making processes.

Looking Ahead

The Pacific Northwest's renewable energy aspirations hinge on modernizing its transmission infrastructure, aligning with decarbonization strategies that emphasize grid buildout. While the BPA has proposed several projects to enhance grid capacity, the timeline for completion remains uncertain. Without significant investment and policy reforms, the region risks falling behind in the transition to a clean energy future. Stakeholders across Oregon and Washington must collaborate to advocate for necessary changes and ensure that the grid can support the growing demand for renewable energy.

The Pacific Northwest's commitment to clean energy is commendable, but achieving these goals requires overcoming substantial infrastructure challenges, and neighboring jurisdictions such as British Columbia have pursued B.C. regulatory streamlining to accelerate projects. Addressing the limitations of the BPA's transmission system is critical to unlocking the full potential of renewable energy in the region. Only through concerted efforts at the federal, state, and local levels can Oregon and Washington hope to realize their green energy ambitions.

Duration Portfolio Energy Storage aligns layered peak demand with right-sized batteries, enabling peak shaving, gas peaker replacement, and solar-plus-storage synergy while improving grid flexibility, reliability, and T&D deferral through two- to four-hour battery durations.

Key Points

An approach that layers battery durations to match peaks, cut costs, replace peakers, and boost grid reliability.

✅ Layers 2- to 4-hour batteries by peak duration

✅ Enables solar-plus-storage and peak shaving

✅ Cuts T&D upgrades, emissions, and fuel costs

The debate over energy storage replacing gas-fired peakers has raged for years, but a new approach that shifts the terms of the argument could lead to an acceleration of storage deployments.

Rather than looking at peak demand as a single mountainous peak, some analysts now advocate a layered approach that allows energy storage to better match peak needs and complement ongoing efforts to improve solar and wind power across the grid.

"You don’t have to have batteries that run to infinity."

Some developers of solar-plus-storage projects, bolstered by cheap batteries, say they can already compete head-to-head with gas-fired peakers. "I can beat a gas peaker anywhere in the country today with a solar-plus-storage power plant," Tom Buttgenbach, president and CEO of developer 8minutenergy Renewables, recently told S&P Global.

Customers are very busy these days and rebate programs need to fit the speed of their life. Participation should be quick, easy, and accessible anywhere.

Others disagree. Storage is not disruptive for generation, but will be disruptive for transmission and distribution, Kris Zadlo, executive vice president and chief development officer at Invenergy, told the audience at a Bloomberg New Energy Finance conference last spring. Invenergy, like many renewable power developers, develops generation, energy storage and transmission projects.

But there is another path that avoids the pitfalls of positions on either end of the all-or-none approach. "Do the analysis of the need itself," Ray Hohenstein, market applications director at Fluence, told Utility Dive. If the need is only two hours in duration, it may be best served by a two-hour battery. "You don’t have to have batteries that run to infinity."

Storage vs. fossil fuel peakers

Energy storage has several benefits over traditional fossil fuel peaking plants, Hohenstein said. It is instantaneous, it has no emissions and requires no fuel, and has limited infrastructure needs. It can also help the grid absorb higher levels of renewable generation by soaking up excess output, such as solar power at noon, and many planned storage additions will be paired with solar in the next few years. But the one thing energy storage cannot do, he said, is provide limitless energy.

So, instead of looking at replacing an individual peaker, Hohenstein advocated a "duration portfolio" approach that uses energy storage to shave peak load.

If the need is for 150 MW of resources that will never need to run for more than two hours at a time, then a battery is "quite cheap," significantly less than a four or eight-hour battery, said Hohenstein. "If you fill up your peak by duration layer, it could be more cost effective."

NREL research driver

Fluence’s approach is informed by research by Paul Denholm and Robert Margolis at the National Renewable Energy Laboratory (NREL), released last spring.

The NREL researchers looked at the California market where they said 11 GW of fossil fuel capacity is expected to be retired by 2029 because of new once-through-cooling requirements that are taking effect. A lot of that capacity is peaking capacity and, according to NREL’s analysis, a large fraction could be replaced with four-hour energy storage, assuming continued storage cost reductions and growth in solar installations.

The key in NREL’s research was the level of solar power penetration. There is a "synergistic" relationship between solar penetration and storage deployment, the researchers wrote, and other studies suggest wind and solar could meet 80% of U.S. demand as these trends continue.
