CAISO Renewable Curtailments reflect grid balancing under transmission congestion and oversupply, reducing solar and wind output while leveraging WEIM trading, battery storage, and transmission expansion to integrate renewables and stabilize demand-supply.

 

Key Points

CAISO renewable curtailments are reductions in wind and solar output to balance grid amid congestion or oversupply.

✅ Driven mainly by transmission congestion, less by oversupply.

✅ Peaks in spring when demand is low and solar output is high.

✅ Mitigated by WEIM trades, new lines, and battery storage growth.

 

The California Independent System Operator (CAISO), the grid operator for most of the state, is increasingly curtailing solar- and wind-powered electricity generation, as reported in rising curtailments, as it balances supply and demand during the rapid growth of wind and solar power in California.

Grid operators must balance supply and demand to maintain a stable electric system as advances in solar and wind continue to scale. The output of wind and solar generators are reduced either through price signals or rarely, through an order to reduce output, during periods of:

Congestion, when power lines don’t have enough capacity to deliver available energy
Oversupply, when generation exceeds customer electricity demand

In CAISO, curtailment is largely a result of congestion. Congestion-related curtailments have increased significantly since 2019 because California's solar boom has been outpacing upgrades in transmission capacity.

In 2022, CAISO curtailed 2.4 million megawatthours (MWh) of utility-scale wind and solar output, a 63% increase from the amount of electricity curtailed in 2021. As of September, CAISO has curtailed more than 2.3 million MWh of wind and solar output so far this year, even as the US project pipeline is dominated by wind, solar, and batteries.

Solar accounts for almost all of the energy curtailed in CAISO—95% in 2022 and 94% in the first seven months of 2023. CAISO tends to curtail the most solar in the spring when electricity demand is relatively low (because moderate spring temperatures mean less demand for space heating or air conditioning) and solar output is relatively high, although wildfire smoke impacts can reduce available generation during fire season as well.

CAISO has increasingly curtailed renewable generation as renewable capacity has grown in California, and the state has even experienced a near-100% renewables moment on the grid in recent years. In 2014, a combined 9.0 gigawatts (GW) of wind and solar capacity had been built in California. As of July 2023, that number had grown to 17.6 GW. Developers plan to add another 3.0 GW by the end of 2024.

CAISO is exploring and implementing various solutions to its increasing curtailment of renewables, including:

The Western Energy Imbalance Market (WEIM) is a real-time market that allows participants outside of CAISO to buy and sell energy to balance demand and supply. In 2022, more than 10% of total possible curtailments were avoided by trading within the WEIM. A day ahead market is expected to be operational in Spring 2025.

CAISO is expanding transmission capacity to reduce congestion. CAISO’s 2022–23 Transmission Planning Process includes 45 transmission projects to accommodate load growth and a larger share of generation from renewable energy sources.

CAISO is promoting the development of flexible resources that can quickly respond to sudden increases and decreases in demand such as battery storage technologies that are rapidly becoming more affordable. California has 4.9 GW of battery storage, and developers plan to add another 7.6 GW by the end of 2024, according to our survey of recent and planned capacity changes. Renewable generators can charge these batteries with electricity that would otherwise have been curtailed.

France Hits Record: 20% Of Market Buys Electric Cars

France Plug-In Electric Car Sales September 2023 show rapid EV adoption: 45,872 plug-ins, 30% market share, BEV 19.6%, PHEV 10.2%, with Tesla Model Y leading registrations amid sustained year-over-year growth.

 

Key Points

France registered 45,872 plug-ins in September 2023, a 30% share, with BEVs at 19.6% and PHEVs at 10.2%.

✅ Tesla Model Y led BEVs with 5,035 registrations in September

✅ YTD plug-in share 25%; BEV 15.9%, PHEV 9.1% across passenger cars

✅ Total market up 9% YoY to 153,916; plug-ins up 35% YoY

 

New passenger car registrations in France increased in September by nine percent year-over-year to 153,916, mirroring global EV market growth trends, taking the year-to-date total to 1,286,247 (up 16 percent year-over-year).

The market has been expanding every month this year (recovering slightly from the 2020-2022 collapse and the period when EU EV share grew during lockdowns across the bloc) and also is becoming more and more electrifying thanks to increasing plug-in electric car sales.

According to L’Avere-France, last month 45,872 new passenger plug-in electric cars were registered in France (35 percent more than a year ago), which represented almost 30 percent of the market, aligning with the view that the age of electric cars is arriving ahead of schedule. That's a new record share for rechargeable cars and a noticeable jump compared to just over 24 percent a year ago.

What's even more impressive is that passenger all-electric car registrations increased to over 30,000 (up 34 percent year-over-year), taking a record share of 19.6 percent of the market. That's basically one in five new cars sold, and in the U.S., plug-ins logged 19 billion electric miles in 2021 as a benchmark.

Plug-in hybrids are also growing (up 35% year-over-year), and with 15,699 units sold, accounted for 10.2 percent of the market (a near record value).


Plug-in car sales in France – September 2023

So far this year, more than 341,000 new plug-in electric vehicles have been registered in France, including over 321,000 passenger plug-in cars (25 percent of the market), while in the U.S., EV sales are soaring into 2024 as well.

Plug-in car registrations year-to-date (YOY change):

  • Passenger BEVs: 204,616 (up 45%) and 15.9% market share
  • Passenger PHEVs: 116,446 (up 31%) and 9.1% market share
  • Total passenger plug-ins: 321,062 (up 40%) and 25% market share
  • Light commercial BEVs: 20,292 (up 111%)
  • Light commercial PHEVs: 281 (down 38%)
  • Total plug-ins: 341,635 (up 43%)

For reference, in 2022, more than 346,000 new plug-in electric vehicles were registered in France (including almost 330,000 passenger cars, which was 21.5 percent of the market).

We can already tell that the year 2023 will be very positive for electrification in France, with a potential to reach 450,000 units or so, though new EV incentive rules could reshape the competitive landscape.


Models
In terms of individual models, the Tesla Model Y again was the most registered BEV with 5,035 new registrations in September. This spectacular result enabled the Model Y to become the fifth best-selling model in the country last month (Tesla, as a brand, was seventh).

The other best-selling models are usually small city cars - Peugeot e-208 (3,924), Dacia Spring (2,514), Fiat 500 electric (2,296), and MG4 (1,945), amid measures discouraging Chinese EVs in France. Meanwhile, the best-selling electric Renault - the Megane-e - was outside the top five BEVs, which reveals to us how much has changed since the Renault Zoe times.

After the first nine months of the year, the top three BEVs are the Tesla Model Y (27,458), Dacia Spring (21,103), and Peugeot e-208 (19,074), slightly ahead of the Fiat 500 electric (17,441).

Road to electric vehicle targets in Manitoba not smooth, experts say

Manitoba ZEV Roadblocks highlight EV charging station gaps, rural infrastructure limits, dealership supply shortages, and ZEV mandate timelines, pushing mode shift to transit, cycling, and walking while hampering zero-emission vehicle adoption across the province.

 

Key Points

EV charging gaps, rural access limits, and supply constraints slow Manitoba's progress toward ZEV targets.

✅ Sparse Level 3 fast chargers outside Winnipeg

✅ Rural infrastructure limits long-distance confidence

✅ Dealership supply lags; long pre-order wait times

 

The federal government’s push toward zero-emission vehicles (ZEVs), including forthcoming EV sales regulations, is hitting some roadblocks in Manitoba.

Earlier this year, Ottawa set a sales target to encourage Canadians to choose ZEVs. By 2026, their goal is to have ZEVs make up 20 per cent of new vehicle purchases. By 2035, they want all new vehicles sold to be ZEVs, a target that has sparked 2035 EV mandate debate among industry observers.

READ MORE: Ottawa sets 2026 target for mandating electric vehicle sales

Connie Blixhavn with the Manitoba Electric Vehicle Association (MEVA) doesn’t think Manitoba is on track.

“We’re not, not at all,” she said.

Blixhavn lives in Killarney, Man., and bought an electric vehicle last year. She plans her trips to Brandon and Winkler around the life of her car’s battery, but finds the charging infrastructure to be lacking and unreliable, a challenge echoed by Labrador's lagging infrastructure in Newfoundland and Labrador.

“Brandon is my closest place to get a level three charge, and when they’re not working, it limits where you can go,” she said.

Level three is the fastest type of EV charger, taking about 15-45 minutes to fully charge a vehicle’s batteries.

According to CAA, 68 of the province’s 94 EV charging stations are in Winnipeg. Blixhavn says it limits options for rural people to confidently adopt EVs, even as jurisdictions like the N.W.T. encourage EV adoption through targeted programs.

“I know we’re a big area, but they need to strategically plan where they put these so we all have access,” she said.

ZEVs are often not found on dealership lots – they have to be pre-ordered. One dealership employee told Global News demand far outweighs supply, amid EV shortages and wait times reported nationally, with some customers waiting one to two years for their new vehicle to arrive.

Mel Marginet with the Green Action Centre’s Sustainable Transporation Team is also wary of Manitoba’s ability to meet the 2026 goal, noting that even as experts question Quebec's EV push there are broader challenges. She believes the only way to come close is to change how much Manitobans use personal vehicles altogether.

“If we’re really concerned about the environment, we need to double and triple down on just reducing personal vehicle trips by and large,” she said.

Marginet points to transit, walking and cycling as ways to reduce reliance on driving.

“We depend on personal vehicles a lot in this province, and far more than we should have to,” she said. “My biggest worry is that we’ll take resources away from what we need to build to get people to use personal vehicles less.”

For Blixhavn, the lack of charging stations in her area has caused her to reduce her vehicle use. While she says she’s fine with the extra planning it takes to travel, she believes the lack of infrastructure is preventing Manitobans, especially those in rural areas, from catching up with other provinces, as Atlantic Canada EV interest lags the rest of the country, when it comes to choosing electric vehicles.

Electric vehicle charging network will be only two thirds complete by Friday deadline, Ontario says

Ontario EV Charging Network Delay highlights permitting hurdles, grid limitations, and public-private rollout challenges across 250 sites, as two-thirds of 475 chargers go live while full provincewide infrastructure deployment slips to fall.

 

Key Points

A provincial rollout setback where permitting and grid issues delay full activation of Ontario's 475 public EV chargers.

✅ Two-thirds of 475 chargers live by the initial deadline

✅ Remaining stations expected online by fall

✅ Delays tied to permits, site conditions, and grid capacity

 

The Ontario government admitted Wednesday that it will fall short of meeting its deadline this Friday of creating a network of 475 electric vehicle charging stations in 250 locations across the province, and it's blaming unforeseen problems for the delay.

"We know some of our partners have encountered difficulties around permitting and some of the technical aspects of having some of the chargers up and running, even as we work to make it easier to build EV charging stations across Ontario," said Transportation Minister Steven Del Duca.

Two-thirds of the network will be live on Friday with the rest of the stations expected to be up and running by fall, according to the Ministry of Transportation. 

"Each of our partners' individual charging stations are subject to different site conditions, land ownership, municipal permitting, electrical grid limitations, as seen in regions where EV infrastructure lags, and other factors which have influenced timelines," said Bob Nichols, senior media liaison officer for the Transportation Ministry, in a statement. 

Because the stations are located in various community centres, retail outlets and other public spaces, Del Duca said the government's public and private sector partners are facing challenges in obtaining permits but are "motivated to get it right."

Cara Clairman, president and CEO of Plug'n Drive, an organization dedicated to accelerating the rollout of electric vehicles, says she isn't concerned about the delay.

"It was a pretty aggressive timeline. The EV community is pretty happy with the fact that it is going to happen. It might be slightly delayed but I think overall the mood is positive," she said.

Clairman said there are now more than 10,000 electric vehicles in the province and that more growth is expected as Ontario's next EV wave emerges in the market. She doesn't believe the delay in the rollout of charging stations will deter anyone from purchasing electric vehicles, even amid EV shortages and wait times in some segments.

"It certainly does help to persuade new folks to get on board but I think since they know it is coming, I don't see it having a big impact." 

Horwath not surprised

NDP Leader Andrea Horwath said she's not surprised the government didn't meet its target.

"You shouldn't be making these promises if you can't fulfil them, that's the bottom line," she said. "Let's be realistic with
what you're able to achieve."

Progressive Conservative transportation critic Michael Harris suggested the Liberals don't have their priorities straight when it comes to electric vehicles.

"I think the focus for Kathleen Wynne was handing out $14,000 rebates to owners of Teslas, while they really should have been focusing their time and energy on ensuring that the infrastructure for electric vehicles has actually been rolled out," Harris said.

Covering every corner

Del Duca said the ministry has seen "some fairly tremendous success" despite the delays but that there have been a few challenges in building a network that ranges across the province, even as N.L.'s first fast-charging network is touted as just the beginning elsewhere. 

"We definitely want to make sure we're building a network that covers every corner of Ontario. Yes, we have some challenges and we are slightly delayed," the minister said.

"We anticipate being able to provide more resources in the coming months to continue to deploy an even broader network of charging infrastructure, including in northern Ontario."

Del Duca said a map on the ministry's website showing where the charging stations are installed should be updated in the next few days.

Premier Wynne committed to building a charging network for electric vehicles across Ontario at the 2015 climate change talks in Paris.

The $20 million in funding for the charging stations comes from Ontario's $325 million Green Investment Fund, which supports projects that fight climate change.

More than half of new U.S. electric-generating capacity in 2023 will be solar

U.S. 2023 Utility-Scale Capacity Additions highlight surging solar power, expanding battery storage, wind projects, natural gas plants, and new nuclear reactors, boosting grid reliability in Texas and California with record planned installations.

 

Key Points

Planned grid expansions led by solar and battery storage, with wind, natural gas, and nuclear increasing U.S. capacity.

✅ 29.1 GW solar planned; Texas and California lead installations.

✅ 9.4 GW battery storage to more than double current capacity.

✅ Natural gas, wind, and 2.2 GW nuclear round out additions.

 

Developers plan to add 54.5 gigawatts (GW) of new utility-scale electric-generating capacity to the U.S. power grid in 2023, according to our Preliminary Monthly Electric Generator Inventory. More than half of this capacity will be solar power (54%), even as coal generation increase has been reported, followed by battery storage (17%).

 

Solar

U.S. utility-scale solar capacity has been rising rapidly EIA summer outlook since 2010. Despite its upward trend over the past decade 2018 milestone, additions of utility-scale solar capacity declined by 23% in 2022 compared with 2021. This drop in solar capacity additions was the result of supply chain disruptions and other pandemic-related challenges. We expect that some of those delayed 2022 projects will begin operating in 2023, when developers plan to install 29.1 GW of solar power in the United States. If all of this capacity comes online as planned, 2023 will have the most new utility-scale solar capacity added in a single year, more than doubling the current record (13.4 GW in 2021).

In 2023, the most new solar capacity, by far, will be in Texas (7.7 GW) and California (4.2 GW), together accounting for 41% of planned new solar capacity.

 

Battery storage

U.S. battery storage capacity has grown rapidly January generation jump over the past couple of years. In 2023, U.S. battery capacity will likely more than double. Developers have reported plans to add 9.4 GW of battery storage to the existing 8.8 GW of battery storage capacity.

Battery storage systems are increasingly installed with wind and solar power projects. Wind and solar are intermittent sources of generation; they only produce electricity when the wind is blowing or the sun is shining. Batteries can store excess electricity from wind and solar generators for later use. In 2023, we expect 71% of the new battery storage capacity will be in California and Texas, states with significant solar and wind capacity.

 

Natural gas

Developers plan to build 7.5 GW of new natural-gas fired capacity record natural gas output in 2023, 83% of which is from combined-cycle plants. The two largest natural gas plants expected to come online in 2023 are the 1,836 megawatt (MW) Guernsey Power Station in Ohio and the 1,214 MW CPV Three Rivers Energy Center in Illinois.

 

Wind

In 2023, developers plan to add 6.0 GW of utility-scale wind capacity, as renewables poised to eclipse coal in global power generation. Annual U.S. wind capacity additions have begun to slow, following record additions of more than 14 GW in both 2020 and 2021.

The most wind capacity will be added in Texas in 2023, at 2.0 GW. The only offshore wind capacity expected to come online this year is a 130.0 MW offshore windfarm in New York called South Fork Wind.

 

Nuclear

Two new nuclear reactors at the Vogtle nuclear power plant in Georgia nuclear and net-zero are scheduled to come online in 2023, several years later than originally planned. The reactors, with a combined 2.2 GW of capacity, are the first new nuclear units built in the United States in more than 30 years.

Developers and power plant owners report planned additions to us in our annual and monthly electric generator surveys. In the annual survey, we ask respondents to provide planned online dates for generators coming online in the next five years. The monthly survey tracks the status of generators coming online based on reported in-service dates.

Ukraine's Green Fightback: Rising from the Ashes with Renewable Energy

Ukraine Green Fightback advances renewable energy, energy independence, and EU integration, rebuilding war-damaged grids with solar, wind, and storage, exporting power to Europe, and scaling community microgrids for resilient, low-carbon recovery and REPowerEU alignment.

 

Key Points

Ukraine Green Fightback shifts to renewables and resilient grids, aiming 50% clean power by 2035 despite wartime damage.

✅ 50% renewable electricity target by 2035, up from 15% in 2021

✅ Community solar and microgrids secure hospitals and schools

✅ Wind and solar rebuild capacity; surplus exports to EU grids

 

Two years after severing ties with Russia's power grid, Ukraine stands defiant, rebuilding its energy infrastructure with a resolute focus on renewables. Amidst the ongoing war's devastation, a remarkable green fightback is taking shape, driven by a vision of a self-sufficient, climate-conscious future.

Energy Independence, Forged in Conflict:

Ukraine's decision to unplug from Russia's grid in 2022 was both a strategic move and a forced necessity, aligning with a wider pushback from Russian oil and gas across the continent. While it solidified energy independence aspirations, the full-scale invasion pushed the country into "island mode," highlighting vulnerabilities of centralized infrastructure.

Today, Ukraine remains deeply intertwined with Europe, inching towards EU accession and receiving global support, as Europe's green surge in clean energy gathers pace. This aligns perfectly with the country's commitment to environmental responsibility, further bolstered by the EU's own "REPowerEU" plan to ditch fossil fuels.

Rebuilding with Renewables:

The war's impact on energy infrastructure has been significant, with nearly half damaged or destroyed. Large-scale renewables have borne the brunt, with 30% of solar and 90% of wind farms facing disruption.

Yet, the spirit of resilience prevails. Surplus electricity generated by solar plants is exported to Poland, showcasing the potential of renewable sources and mirroring Germany's solar power boost across the region. Ambitious projects are underway, like the Tyligulska wind farm, Ukraine's first built in a conflict zone, already supplying clean energy to thousands.

The government's vision is bold: 50% renewable energy share by 2035, a significant leap from 2021's 15%, and informed by the fact that over 30% of global electricity already comes from renewables. This ambition is echoed by civil society groups who urge even higher targets, with calls for 100% renewable energy worldwide continuing to grow.

Community-Driven Green Initiatives:

Beyond large-scale projects, community-driven efforts are flourishing. Villages like Horenka and Irpin, scarred by the war, are rebuilding hospitals and schools with solar panels, ensuring energy security and educational continuity.

These "bright examples," as Svitlana Romanko, founder of Razom We Stand, calls them, pave the way for a broader green wave. Research suggests replacing all coal plants with renewables would cost a manageable $17 billion, paving the way for a future free from dependence on fossil fuels, with calls for a fossil fuel lockdown gaining traction.

Environmental Cost of War:

The war's ecological footprint is immense, with damages exceeding €56.7 billion. The Ministry of Environmental Protection and Natural Resources is meticulously documenting this damage, not just for accountability but for post-war restoration.

Their efforts extend beyond documentation. Ukraine's "EcoZagroza" app allows citizens to report environmental damage and monitor pollution levels, fostering a collaborative approach to environmental protection.

Striving for a Greener Future:

President Zelenskyy's peace plan highlights ecocide prevention and environmental restoration. The ministry itself is undergoing a digitalization push, tackling corruption and implementing EU-aligned reforms.

While the European Commission's recent progress report acknowledges Ukraine's strides, set against a Europe where renewable power has surpassed fossil fuels for the first time, the "crazy rhythm" of change, as Ecoaction's Anna Ackermann describes it, reflects the urgency of the situation. Finding the right balance between war efforts and green initiatives remains a crucial challenge.

Conclusion:

Ukraine's green fightback is a testament to its unwavering spirit. Amidst the darkness of war, hope shines through in the form of renewable energy projects and community-driven initiatives. By embracing a green future, Ukraine not only rebuilds but sets an example for the world, demonstrating that even in the face of adversity, sustainability can prevail.

BC's Kootenay Region makes electric cars a priority

Accelerate Kootenays EV charging stations expand along Highway 3, adding DC fast charging and Level 2 plugs to cut range anxiety for electric vehicles in B.C., linking communities like Castlegar, Greenwood, and the Alberta border.

 

Key Points

A regional network of DC fast and Level 2 chargers along B.C.'s Highway 3 to reduce range anxiety and boost EV adoption.

✅ 13 DC fast chargers plus 40 Level 2 stations across key hubs

✅ 20-minute charging stops reduce range anxiety on Highway 3

✅ Backed by BC Hydro, FortisBC, and regional districts

 

The Kootenays are B.C.'s electric powerhouse, and as part of B.C.'s EV push the region is making significant advances to put electric cars on the road.

The region's dams generate more than half of the province's electricity needs, but some say residents in the region have not taken to electric cars, for instance.

Trish Dehnel is a spokesperson for Accelerate Kootenays, a multi-million dollar coalition involving the regional districts of East Kootenay, Central Kootenay and Kootenay Boundary, along with a number of corporate partners including Fortis B.C. and BC Hydro.

She says one of the major problems in the region — in addition to the mountainous terrain and winter driving conditions — is "range anxiety."

That's when you're not sure your electric vehicle will be able to make it to your destination without running out of power, she explained.

Now, Accelerate Kootenays is hoping a set of new electric charging stations, part of the B.C. Electric Highway project expanding along Highway 3, will make a difference.

 

No more 'range anxiety'

The expansion includes 40 Level 2 stations and 13 DC Quick Charging stations, mirroring BC Hydro's expansion across southern B.C. strategically located within the region to give people more opportunities to charge up along their travel routes, Dehnel said.

"We will have DC fast-charging stations in all of the major communities along Highway 3 from Greenwood to the Alberta border. You will be able to stop at a fast-charging station and, thanks to faster EV charging technology, charge your vehicle within 20 minutes," she said.

Castlegar car salesman Terry Klapper — who sells the 2017 Chevy Bolt electric vehicle — says it's a great step for the region as sites like Nelson's new fast-charging station come online.

"I guarantee that you'll be seeing electric cars around the Kootenays," he said.

"The interest the public has shown … [I mean] as soon as people found out we had these Bolts on the lot, we've had people coming in every single day to take a look at them and say when can I finally purchase it."

The charging stations are set to open by the end of next year.
