Ontario is strengthening and modernizing Toronto's electricity transmission grid by replacing aging infrastructure and increasing capacity to ensure a reliable electricity supply.

Construction of a 2.4 kilometre long tunnel from Bayview Avenue to Yonge Street is set to begin as part of Hydro One's Midtown Electricity Infrastructure Renewal Project.

A specialized 120 tonne boring machine will start tunnelling this September to make room for six high voltage cables that will carry an additional 100 megawatts of power, enough electricity to power 25,000 homes.

The project will create 30 jobs and will help make Ontario's current energy infrastructure more efficient. Construction is scheduled for completion by the end of 2014.

Strengthening Ontario's electricity infrastructure is an important part of the McGuinty Government's plan to build a modern, clean, reliable electricity system. This will ensure the province has the electricity it needs to power our homes, schools, hospitals and our economy.

QUICK FACTS -- The tunnel will be 60 meters below the ground and almost 2.4 kilometers long.

-- The midtown power corridor was originally built in the 1920s and the first underground cable in the corridor was laid in the 1950s.

-- The midtown power corridor serves many central neighborhoods in Toronto, including areas north to St. Clair Avenue West, east to Mount Pleasant, south to Queen Street, and west to Jane Street.

The province is rebuilding or replacing approximately 80 percent of its electricity generating fleet while also investing in upgrading and sustaining the power grid.

BC Hydro Expects To See Electricity Usage Rise This Holiday Season

BC Hydro Holiday Electricity Usage is set to rise as energy demand increases during peak 4-10 pm on Christmas and Boxing Day, driven by larger gatherings, more cooking, and eased COVID-19 restrictions province-wide.

 

Key Points

Expected rise in power demand on Christmas and Boxing Day evenings versus 2020, driven by larger gatherings and cooking.

✅ Peak hours 4-10 pm expected to rise in provincial load.

✅ 2020 saw 4% and 7% drops vs 2019 on Christmas and Boxing Day.

✅ Holiday lighting adds ~3% to use; switching to LED can save ~$40.

 

BC Hydro data showed residential electricity load in the Cariboo and throughout the province, even as drought affects generation dynamics heading into winter, dropped on Christmas Day and Boxing Day in 2020.

Northern Community Relations Manager, Bob Gammer, said the decrease was due in part to more people following the COVID-19 restrictions and not getting together for big meals, even though 2018 Earth Hour usage increased elsewhere illustrates how behavior can sometimes raise demand.

However, this year Gammer said between 4 and 10 pm on those two days, BC Hydro does expect to see a change in overall usage, aligning with all-time high demand trends reported recently in B.C.

“On Christmas Day and Boxing Day, we expect to see increases through those hours and a little bit more so between 4 and 10 pm we should see the amount of power being consumed across the province, as record-breaking 2021 demand indicated earlier, going up compared to what it was on those two days last year.”

In 2020 on Christmas Day evening hydro usage dropped by over 4 percent and Boxing Day evening decreased by 7 percent compared to 2019, whereas regions like Calgary's winter demand have seen spikes during extreme cold.

Gammer added after BC Hydro surveyed their customers and introduced a winter payment plan, they expect to see a lot more cooking happening on Christmas Day and Boxing Day this year as people are intending to have larger gatherings and visit friends.

We asked Gammer about hydro usage when it comes to homes decked out for the holidays, and how that compares to newer loads like crypto mining activity in B.C.

“The Christmas lighting displays people have, not just indoors but outdoors as well, what we’re seeing is about a 3 percent increase in electricity consumption overall through the Christmas season. If people switch, if you still have older lights that are incandescent, switch those over to LED, and through the season it could wind up saving you $40 in electricity just switching over about 8 strings of lights to LED.”

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

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

 

Key Points

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

✅ $38.40 fixed charge regardless of usage

✅ Disincentivizes rooftop solar investments

✅ Disproportionate impact on low income customers

 

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

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

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

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

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

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

Paris Finalises Energy Roadmap for 2025–2035 with Imminent Decree

France 2025–2035 Energy Roadmap accelerates carbon neutrality via renewables expansion, energy efficiency, EV adoption, heat pumps, hydrogen, CCS, nuclear buildout, and wind and solar targets, cutting fossil fuels and emissions across transport, housing, industry.

 

Key Points

A national plan to cut fossil use and emissions, boost renewables, and scale efficiency and clean technologies.

✅ Cuts fossil share to 30% by 2035 with efficiency gains

✅ Scales solar PV and wind; revives nuclear with EPR 2

✅ Electrifies transport and industry with EVs, hydrogen, CCS

 

Paris is on the verge of finalising its energy roadmap for the period 2025–2035, with an imminent decree expected to be published by the end of the first quarter of 2025. This roadmap is part of France's broader strategy to achieve carbon neutrality by 2050, aligning with wider moves toward clean electricity regulations in other jurisdictions.

Key Objectives of the Roadmap

The energy roadmap outlines ambitious targets for reducing greenhouse gas emissions across various sectors, including transport, housing, food, and energy. The primary goals are:

  • Reducing Fossil Fuel Dependency: Building on the EU's plan to dump Russian energy, the share of fossil fuels in final energy consumption is to fall from 60% in 2022 to 42% in 2030 and 30% in 2035.

  • Enhancing Energy Efficiency: A target of a 28.6% reduction in energy consumption between 2012 and 2030 is set, focusing on conservation and energy efficiency measures.

  • Expanding Decarbonised Energy Production: The roadmap aims to accelerate the development of renewable energies and the revival.

Sector-Specific Targets

  • Transport: The government aims to cut emissions by 31, focusing on the growth of electric vehicles, increasing public transport, and expanding charging infrastructure.

  • Housing: Emissions from buildings are to be reduced by 44%, with plans to replace 75% of oil-fired and install 1 million heat pumps.

  • Agriculture and Food: The roadmap includes measures to reduce emissions from agriculture by 9%, promoting organic farming and reducing the use of nitrogen fertilizers.

  • Industry: A 37% reduction in emissions is targeted through the use of electricity, biomass, hydrogen, and CO₂ capture and storage technologies informed by energy technology pathways outlined in ETP 2017.

Renewable Energy Targets

The roadmap sets ambitious targets for renewable energy production that align with Europe's ongoing electricity market reform efforts:

  • Photovoltaic Power: A sixfold increase in photovoltaic power between 2022

  • Offshore Wind Power: Reaching 18 gigawatts up from 0.6 GW

  • Onshore Wind Power: Doubling capacity from 21 GW to 45 GW over the same period.

  • Nuclear Power: The commissioning of the evolutionary power and the construction of six EPR 2 reactors, underpinned by France's deal on electricity prices with EDF to support long-term investment, with the potential for eight more.
     

Implementation and Governance

The final version of the roadmap will be adopted by decree, alongside a proposed electricity pricing scheme to address EU concerns, rather than being enshrined in law as required by the Energy Code. The government had previously abandoned the energy-climate planning. The decree is expected to be published at the end of the Multiannual Energy Program (PPE) and in the second half of the third National Low-Carbon Strategy (SNBC).

Paris's finalisation of its energy roadmap for 2025–2035 marks a significant step towards achieving carbon neutrality by 2050. The ambitious targets set across various sectors reflect a comprehensive approach to reducing greenhouse gas emissions and transitioning to a more sustainable energy system amid the ongoing EU electricity reform debate shaping market rules. The imminent decree will provide the legal framework necessary to implement these plans and drive the necessary changes across the country.

Renewables surpass coal in US energy generation for first time in 130 years

Renewables Overtake Coal in the US, as solar, wind, and hydro expand grid share; EIA data show an energy transition accelerated by COVID-19, slashing emissions, displacing fossil fuels, and reshaping electricity generation and climate policy.

 

Key Points

It refers to the milestone where US renewable energy generation surpassed coal, marking a pivotal energy transition.

✅ EIA data show renewables topped coal consumption in 2019.

✅ Solar, wind, and hydro displaced aging, costly coal plants.

✅ COVID-19 demand drop accelerated the energy transition.

 

Solar, wind and other renewable sources have toppled coal in energy generation in the United States for the first time in over 130 years, with the coronavirus pandemic accelerating a decline in coal that has profound implications for the climate crisis.

Not since wood was the main source of American energy in the 19th century has a renewable resource been used more heavily than coal, but 2019 saw a historic reversal, building on wind and solar reaching 10% of U.S. generation in 2018, according to US government figures.

Coal consumption fell by 15%, down for the sixth year in a row, while renewables edged up by 1%, even as U.S. electricity use trended lower. This meant renewables surpassed coal for the first time since at least 1885, a year when Mark Twain published The Adventures of Huckleberry Finn and America’s first skyscraper was erected in Chicago.

Electricity generation from coal fell to its lowest level in 42 years in 2019, with the US Energy Information Administration (EIA) forecasting that renewables will eclipse coal as an electricity source this year, while a global eclipse by 2025 is also projected. On 21 May, the year hit its 100th day in which renewables have been used more heavily than coal.

“Coal is on the way out, we are seeing the end of coal,” said Dennis Wamsted, analyst at the Institute for Energy Economics and Financial Analysis. “We aren’t going to see a big resurgence in coal generation, the trend is pretty clear.”

The ongoing collapse of coal would have been nearly unthinkable a decade ago, when the fuel source accounted for nearly half of America’s generated electricity, even as a brief uptick in 2021 was anticipated. That proportion may fall to under 20% this year, with analysts predicting a further halving within the coming decade.

A rapid slump since then has not been reversed despite the efforts of the Trump administration, which has dismantled a key Barack Obama-era climate rule to reduce emissions from coal plants and eased requirements that prevent coal operations discharging mercury into the atmosphere and waste into streams.

Coal releases more planet-warming carbon dioxide than any other energy source, with scientists warning its use must be rapidly phased out to achieve net-zero emissions globally by 2050 and avoid the worst ravages of the climate crisis.

Countries including the UK and Germany are in the process of winding down their coal sectors, and in Europe renewables are increasingly crowding out gas as well, although in the US the industry still enjoys strong political support from Trump.

“It’s a big moment for the market to see renewables overtake coal,” said Ben Nelson, lead coal analyst at Moody’s. “The magnitude of intervention to aid coal has not been sufficient to fundamentally change its trajectory, which is sharply downwards.”

Nelson said he expects coal production to plummet by a quarter this year but stressed that declaring the demise of the industry is “a very tough statement to make” due to ongoing exports of coal and its use in steel-making. There are also rural communities with power purchase agreements with coal plants, meaning these contracts would have to end before coal use was halted.

The coal sector has been beset by a barrage of problems, predominantly from cheap, abundant gas that has displaced it as a go-to energy source. The Covid-19 outbreak has exacerbated this trend, even as global power demand has surged above pre-pandemic levels. With plunging electricity demand following the shutting of factories, offices and retailers, utilities have plenty of spare energy to choose from and coal is routinely the last to be picked because it is more expensive to run than gas, solar, wind or nuclear.

Many US coal plants are ageing and costly to operate, forcing hundreds of closures over the past decade. Just this year, power companies have announced plans to shutter 13 coal plants, including the large Edgewater facility outside Sheboygan, Wisconsin, the Coal Creek Station plant in North Dakota and the Four Corners generating station in New Mexico – one of America’s largest emitters of carbon dioxide.

The last coal facility left in New York state closed earlier this year.

The additional pressure of the pandemic “will likely shutter the US coal industry for good”, said Yuan-Sheng Yu, senior analyst at Lux Research. “It is becoming clear that Covid-19 will lead to a shake-up of the energy landscape and catalyze the energy transition, with investors eyeing new energy sector plays as we emerge from the pandemic.”

Climate campaigners have cheered the decline of coal but in the US the fuel is largely being replaced by gas, which burns more cleanly than coal but still emits a sizable amount of carbon dioxide and methane, a powerful greenhouse gas, in its production, whereas in the EU wind and solar overtook gas last year.

Renewables accounted for 11% of total US energy consumption last year – a share that will have to radically expand if dangerous climate change is to be avoided. Petroleum made up 37% of the total, followed by gas at 32%. Renewables marginally edged out coal, while nuclear stood at 8%.

“Getting past coal is a big first hurdle but the next round will be the gas industry,” said Wamsted. “There are emissions from gas plants and they are significant. It’s certainly not over.”

Lawmakers push bill to connect Texas grid to rest of the nation

Connect the Grid Act links ERCOT to neighboring grids via high-voltage interconnections, enhancing reliability, resilience, and renewables integration. It enables power imports and exports with SPP, MISO, and the Western Interconnection under FERC oversight.

 

Key Points

A plan to link ERCOT with neighboring grids, improving reliability, enabling energy trade, and integrating renewables.

✅ High-voltage ties with SPP, MISO, and the Western Interconnection

✅ Enables imports during crises and exports of surplus power

✅ Brings ERCOT under FERC oversight; DoE to study Mexico links

 

In the aftermath of the devastating 2021 Texas blackouts, which exposed the vulnerabilities of the state's energy infrastructure, a significant legislative effort is underway to transform Texas from an energy island into a connected component of the broader U.S. power grid. Spearheaded by U.S. Representative Greg Casar, D-Austin, the proposed Connect the Grid Act is part of a push for smarter electricity infrastructure that seeks to remedy the isolation of the Electric Reliability Council of Texas (ERCOT) from neighboring power grids, a condition that significantly contributed to the crisis during Winter Storm Uri.

The blackouts, which left millions without power and resulted in significant loss of life and economic damage, underscored the inherent risks of Texas's unique energy infrastructure. Unlike the rest of the continental U.S., Texas's grid operates independently, limiting its ability to import electricity during emergencies. This isolation was a critical factor in the state's inability to respond effectively to the increased demand for power during the storm.

Recognizing the urgent need for a more resilient and integrated energy system, Rep. Casar's legislation aims to establish high-voltage connections between ERCOT and adjacent grid-operating organizations, including the Southern Power Pool, MISO, and the Western Interconnection. This would not only improve the reliability of Texas's power supply by enabling energy imports during crises but also allow the state to export surplus energy, thereby enhancing the economic efficiency and sustainability of its energy market.

The Connect the Grid Act proposes a range for the new connections' transfer capabilities, aiming to significantly boost the amount of power that can be shared between Texas and its neighbors. Such interconnectivity is anticipated to reduce energy costs for consumers by mitigating scarcity and enabling access to Texas's vast renewable energy resources, even as grid modernization affordability remains a point of debate among stakeholders. However, the bill faces opposition due to concerns over federal oversight, as it would bring ERCOT under the jurisdiction of the Federal Energy Regulatory Commission (FERC).

Some analysts note that policies such as later school start dates can ease late-summer peak demand as well.

At a press conference held at the IBEW Local 520 headquarters, Rep. Casar, along with environmental groups, labor unions, and frontline workers, highlighted the benefits of the proposed legislation. The bill also includes provisions for a Department of Energy study on the potential benefits of interconnecting with Mexico, and parallels proposals for macrogrids in Canada that seek greater reliability across borders.

The Connect the Grid Act reflects a broader national trend towards increasing the interconnectivity of regional power grids, a move deemed essential for the transition to renewable energy and combating climate change risks to the U.S. grid through expanded interconnection. By enabling the flow of clean energy from renewable-rich areas like Texas to energy-hungry urban centers, the legislation supports a more sustainable and resilient national energy infrastructure.

Critics of Texas's grid independence, including energy experts and federal regulators, have long advocated for such interconnections. They argue that increased access to neighboring grids could have mitigated the effects of the 2021 blackouts and emphasize the importance of a grid that can withstand extreme weather events. The Federal Energy Regulatory Commission and the North American Electric Reliability Corp. have both explored mandates and studies to promote electricity transfer between regional grids, while states like California grid upgrades are investing to modernize networks as well, highlighting the national importance of grid interconnectivity.

Despite the potential challenges of increased federal regulation, proponents of the Connect the Grid Act argue that the benefits of interconnection far outweigh the drawbacks. By reducing energy costs, enhancing grid reliability, and promoting renewable energy, the legislation aims to secure a more sustainable and equitable energy future for Texas and the nation.

If passed, the Connect the Grid Act would mark a historic shift in Texas's energy policy, ending the state's long-standing isolation and positioning it as a key player in the national and potentially international energy landscape, and echoes calls for a western Canadian electricity grid to strengthen regional ties. The bill sets a completion deadline of January 1, 2035, for the construction of the new connections, with other projects, like the one by Pattern Energy, potentially connecting ERCOT to parts of the Southeastern grid even earlier, by 2029. This legislative effort represents a critical step towards ensuring that Texas can meet its energy needs reliably and sustainably, while also contributing to the broader goal of transitioning to a cleaner, more resilient power system.

Cost of US nuclear generation at ten-year low

US Nuclear Generating Costs 2017 show USD33.50/MWh for nuclear energy, the lowest since 2008, as capital expenditures, fuel costs, and operating costs declined after license renewals and uprates, supporting a reliable, low-carbon grid.

 

Key Points

The 2017 US nuclear average was USD33.50/MWh, lowest since 2008, driven by reduced capital, fuel, and operating costs.

✅ Average cost USD33.50/MWh, lowest since 2008

✅ Capital, fuel, O&M costs fell sharply since 2012 peak

✅ License renewals, uprates, market reforms shape competitiveness

 

Average total generating costs for nuclear energy in 2017 in the USA were at their lowest since 2008, according to a study released by the Nuclear Energy Institute (NEI), amid a continuing nuclear decline debate in other regions.

The report, Nuclear Costs in Context, found that in 2017 the average total generating cost - which includes capital, fuel and operating costs - for nuclear energy was USD33.50 per megawatt-hour (MWh), even as interest in next-generation nuclear designs grows among stakeholders. This is 3.3% lower than in 2016 and more than 19% below 2012's peak. The reduction in costs since 2012 is due to a 40.8% reduction in capital expenditures, a 17.2% reduction in fuel costs and an 8.7% reduction in operating costs, the organisation said.

The year-on-year decline in capital costs over the past five years reflects the completion by most plants of efforts to prepare for operation beyond their initial 40-year licence. A few major items - a series of vessel head replacements; steam generator replacements and other upgrades as companies prepared for continued operation, and power uprates to increase output from existing plants - caused capital investment to increase to a peak in 2012. "As a result of these investments, 86 of the [USA's] 99 operating reactors in 2017 have received 20-year licence renewals and 92 of the operating reactors have been approved for uprates that have added over 7900 megawatts of electricity capacity. Capital spending on uprates and items necessary for operation beyond 40 years has moderated as most plants are completing these efforts," it says.

Since 2013, seven US nuclear reactors have shut down permanently, with the Three Mile Island debate highlighting wider policy questions, and another 12 have announced their permanent shutdown. The early closure for economic reasons of reliable nuclear plants with high capacity factors and relatively low generating costs will have long-term economic consequences, the report warns: replacement generating capacity, when needed, will produce more costly electricity, fewer jobs that will pay less, and, for net-zero emissions objectives, more pollution, it says.

NEI Vice President of Policy Development and Public Affairs John Kotek said the "hardworking men and women of the nuclear industry" had done an "amazing job" reducing costs through the institute's Delivering the Nuclear Promise campaign and other initiatives, in line with IAEA low-carbon lessons from the pandemic. "As we continue to face economic headwinds in markets which do not properly compensate nuclear plants, the industry has been doing its part to reduce costs to remain competitive," he said.

"Some things are in urgent need of change if we are to keep the nation's nuclear plants running and enjoy their contribution to a reliable, resilient and low-carbon grid. Namely, we need to put in place market reforms that fairly compensate nuclear similar to those already in place in New York, Illinois and other states," Kotek added.

Cost information in the study was collected by the Electric Utility Cost Group with prior years converted to 2017 dollars for accurate historical comparison.
