Energy-wise legislation passed by House

PG&E Wind Shutdown and Renewable Reliability examines PSPS strategy, wildfire risk, transmission line exposure, wind turbine cut-out speeds, grid stability, and California's energy mix amid historic high-wind events and supply constraints across service areas.

Key Points

An overview of PG&E's PSPS decisions, wildfire mitigation, and how wind cut-out limits influence grid reliability.

✅ Wind turbines reach cut-out near 55 mph, reducing generation.

✅ PSPS mitigates ignition from damaged transmission infrastructure.

✅ Baseload diversity improves resilience during high-wind events.

According to the official, widely reported story, Pacific Gas & Electric (PG&E) initiated power shutoffs across substantial portions of its electric transmission system in northern California as a precautionary measure.

Citing high wind speeds they described as “historic,” the utility claims that if it didn’t turn off the grid, wind-caused damage to its infrastructure could start more wildfires.

Perhaps that’s true. Perhaps. This tale presumes that the folks who designed and maintain PG&E’s transmission system are unaware of or ignored the need to design it to withstand severe weather events, and that the Federal Energy Regulatory Commission (FERC) and North American Electric Reliability Corp. (NERC) allowed the utility to do so.

Ignorance and incompetence happens, to be sure, but there’s much about this story that doesn’t smell right—and it’s disappointing that most journalists and elected officials are apparently accepting it without question.

Take, for example, this statement from a Fox News story about the Kincade Fires: “A PG&E meteorologist said it’s ‘likely that many trees will fall, branches will break,’ which could damage utility infrastructure and start a fire.”

Did you ever notice how utilities cut wide swaths of trees away when transmission lines pass through forests? There’s a reason for that: When trees fall and branches break, the grid can still function, and even as the electric rhythms of New York City shifted during COVID-19, operators planned for variability.

So, if badly designed and poorly maintained infrastructure isn’t the reason PG&E cut power to millions of Californians, what might have prompted them to do so? Could it be that PG&E’s heavy reliance on renewable energy means they don’t have the power to send when a “historic” weather event occurs, especially as policymakers weigh the postponed closure of three power plants elsewhere in California?

Wind Speed Limits

The two most popular forms of renewable energy come with operating limitations, which is why some energy leaders urge us to keep electricity options open when planning the grid. With solar power, the constraint is obvious: the availability of sunlight. One doesn’t generate solar power at night and energy generation drops off with increasing degrees of cloud cover during the day.

The main operating constraint of wind power is, of course, wind speed, and even in markets undergoing 'transformative change' in wind generation, operators adhere to these technical limits. At the low end of the scale, you need about a 6 or 7 miles-per-hour wind to get a turbine moving. This is called the “cut-in speed.” To generate maximum power, about a 30 mph wind is typically required. But, if the wind speed is too high, the wind turbine will shut down. This is called the “cut-out speed,” and it’s about 55 miles per hour for most modern wind turbines.

It may seem odd that wind turbines have a cut-out speed, but there’s a very good reason for it. Each wind turbine rotor is connected to an electric generator housed in the turbine nacelle. The connection is made through a gearbox that is sized to turn the generator at the precise speed required to produce 60 Hertz AC power.

The blades of the wind turbine are airfoils, just like the wings of an airplane. Adjusting the pitch (angle) of the blades allows the rotor to maintain constant speed, which, in turn, allows the generator to maintain the constant speed it needs to safely deliver power to the grid. However, there’s a limit to blade pitch adjustment. When the wind is blowing so hard that pitch adjustment is no longer possible, the turbine shuts down. That’s the cut-out speed.

Now consider how California’s power generation profile has changed. According to Energy Information Administration data, the state generated 74.3 percent of its electricity from traditional sources—fossil fuels and nuclear, amid debates over whether to classify nuclear as renewable—in 2001. Hydroelectric, geothermal, and biomass-generated power accounted for most of the remaining 25.7 percent, with wind and solar providing only 1.98 percent of the total.

By 2018, the state’s renewable portfolio had jumped to 43.8 percent of total generation, with clean power increasing and wind and solar now accounting for 17.9 percent of total generation. That’s a lot of power to depend on from inherently unreliable sources. Thus, it wouldn’t be at all surprising to learn that PG&E didn’t stop delivering power out of fear of starting fires, but because it knew it wouldn’t have power to deliver once high winds shut down all those wind turbines

Paris E-Scooter Ban: Voters back ending rental scooters after a public consultation, citing road safety, pedestrian clutter, and urban mobility concerns; impacts Lime, Dott, and Tier operations across the capital.

Key Points

A citywide prohibition on rental e-scooters, approved by voters, to improve safety, order, and walkability.

✅ Non-binding vote shows about 90% support citywide.

✅ About 15,000 rental scooters from Lime, Dott, Tier affected.

✅ Cites 2022 injuries, fatalities, and sidewalk clutter.

Parisians have voted to rid the streets of the French capital of rental electric scooters, with an overwhelming 90% of votes cast supporting a ban, official results show, amid a wider debate over the limits of the electric-car revolution and its real-world impact.

Paris was a pioneer when it introduced e-scooters, or trottinettes, in 2018 as the city’s authorities sought to promote non-polluting forms of urban transport, amid record EV adoption in France across the country.

But as the two-wheeled vehicles grew in popularity, especially among young people, and, with similar safety concerns prompting the TTC winter ban on lithium-ion e-bikes and scooters in Toronto, so did the number of accidents: in 2022, three people died and 459 were injured in e-scooter accidents in Paris.

In what was billed as a “public consultation” voters were asked: “For or against self-service scooters?”

Twenty-one polling stations were set up across the city and were open until 7pm local time. Although 1.6 million people are eligible to vote, turnout is expected to be low.

The ban won between 85.77% and 91.77% of the votes in the 20 Paris districts that published results, according to the City of Paris website on what was billed as a rare “public consultation” and prompted long queues at ballot boxes around the city. The vote was non-binding but city authorities have vowed to follow the result, echoing Britain's transport rethink that questions simple fixes.

Paris’s socialist mayor, Anne Hidalgo, has promoted cycling and bike-sharing but supported a ban on e-scooters, as France rolls out new EV incentive rules affecting Chinese manufacturers.

In an interview with Agence France-Presses last week, Hidalgo said “self-service scooters are the source of tension and worry” for Parisians and that a ban would “reduce nuisance” in public spaces, with broader benefits for air quality noted in EV use linked to fewer asthma ER visits in recent studies as well.

Paris has almost 15,000 e-scooters across its streets, operated by companies including Lime, Dott and Tier. Detractors argue that e-scooter users disrespect the rules of the road and regularly flout a ban on riding on pavements, even as France moves to discourage Chinese EV purchases to shape the broader mobility market. The vehicles are also often haphazardly parked or thrown into the River Seine.

In June 2021, a 31-year-old Italian woman was killed after being hit by an e-scooter with two passengers onboard while walking along the Seine.

“Scooters have become my biggest enemy. I’m scared of them,” Suzon Lambert, a 50-year-old teacher from Paris, told AFP. “Paris has become a sort of anarchy. There’s no space any more for pedestrians.”

Another Parisian told BFMTV: “It’s dangerous, and people use them badly. I’m fed up.”

Julian Sezgin, aged 15, said he often saw groups of two or three teenagers on e-scooters zooming past cars on busy roads. “I avoid going on e-scooters and prefer e-bikes as, in my opinion, they are safer and more efficient,” he told the Guardian.

Bianca Sclavi, an Italian who has lived in Paris for years, said the scooters go “too fast” and should be mechanically limited so they go slower. “They are dangerous because they zip in and out of traffic,” she said. “However, it is not as bad as when they first arrived … the most dangerous are the drunk tourists!”

Self-healing grid technology automatically reroutes power to reduce outages, speed restoration, and boost reliability during storms like Hurricane Ian in Florida, leveraging smart grid sensors, automation, and grid hardening to support Duke Energy customers.

Key Points

Automated smart grid systems that detect faults and reroute power to minimize outages and accelerate restoration.

✅ Cuts outage duration via automated fault isolation

✅ Reroutes electricity with sensors and distribution automation

✅ Supports storm resilience and faster field crew restoration

As Hurricane Ian made its way across Florida, where restoring power in Florida can take weeks in hard-hit areas, Duke Energy's grid improvements were already on the job helping to combat power outages from the storm.

Smart, self-healing technology, similar to smart grid improvements elsewhere, helped to automatically restore more than 160,000 customer outages and saved nearly 3.3 million hours (nearly 200 million minutes) of total lost outage time.

"Hurricane Ian is a strong reminder of the importance of grid hardening and storm preparedness to help keep the lights on for our customers," said Melissa Seixas, Duke Energy Florida state president. "Self-healing technology is just one of many grid improvements that Duke Energy is making to avoid outages, restore service faster and increase reliability for our customers."

Much like the GPS in your car can identify an accident ahead and reroute you around the incident to keep you on your way, self-healing technology is like a GPS for the grid. The technology can quickly identify power outages and alternate energy pathways to restore service faster for customers when an outage occurs.

Additionally, self-healing technology provides a smart tool to assist crews in the field with power restoration after a major storm like Ian, helping reduce outage impacts and freeing up resources to help restore power in other locations.

Three days after Hurricane Ian exited the state, Duke Energy Florida wrapped up restoration of approximately 1 million customers. This progress enabled the company to deploy more than 550 Duke Energy workers from throughout Florida, as well as contractors from across the country, to help restore power for Lee County Electric Cooperative customers.

Crews worked in Cape Coral and Pine Island, one of the hardest-hit areas in the storm's path, as Canadian power crews have in past storms, and completed power restoration for the majority of customers on Pine Island within approximately one week after arriving to the island.

Prior to Ian in 2022, smart, self-healing technology had helped avoid nearly 250,000 extended customer outages in Florida, similar to Hydro One storm recovery efforts, saving around 285,000 hours (17.1 million minutes) of total lost outage time.

Duke Energy currently serves around 59% of customers in Florida with self-healing capabilities on its main power distribution lines, with a goal of serving around 80% over the next few years.

Japan Offshore Wind Investment signals Japanese utilities entering UK offshore wind, as J-Power and Kansai Electric buy into Innogy's Triton Knoll, leveraging North Sea expertise, 9.5MW turbines, and 15-year fixed-rate contracts.

Key Points

Japanese utilities buying UK offshore wind stakes to import expertise, as J-Power and Kansai join Innogy's Triton Knoll.

✅ $900M deal: J-Power 25%, Kansai Electric ~16% in Innogy unit

✅ Triton Knoll: 860MW, up to 90 9.5MW turbines, 15-year fixed PPA

✅ Goal: Transfer North Sea expertise to develop Japan offshore wind

Two of Japan's biggest power companies will buy around 40% of a German-owned developer of offshore wind farms in the U.K., seeking to learn from Britain's lead in this sector, as highlighted by a UK offshore wind milestone this week, and bring the know-how back home.

Tokyo-based Electric Power Development, better known as J-Power, will join Osaka regional utility Kansai Electric Power in investing in a unit of Germany's Innogy.

The deal, estimated to be worth around $900 million, will give J-Power a 25% stake and Kansai Electric a roughly 16% share. It will mark the first investment in an offshore wind project by Japanese power companies, as other markets shift strategies, with Poland backing wind over nuclear signaling broader momentum.

Innogy plans to start up the 860-megawatt Triton Knoll offshore wind project -- one of the biggest of its kind in the world -- in the North Sea in 2021. The vast installation will have up to 90 9.5MW turbines and sell its output to local utilities under a 15-year fixed-rate contract.

J-Power, which supplies mainly fossil-fuel-based electricity to Japanese regional utilities, will set up a subsidiary backed by the government-run Development Bank of Japan to participate in the Innogy project. Engineers will study firsthand construction and maintenance methods.

While land-based wind turbines are proliferating worldwide, offshore wind farms have progressed mainly in Europe, though U.S. offshore wind competitiveness is improving in key markets. Installed capacity totaled more than 18,000MW at the end of 2017, which at maximum capacity can produce as much power as 18 nuclear reactors.

Japan has hardly any offshore wind farms in commercial operation, and has little in the way of engineering know-how in this field or infrastructure for linking such installations to the land power grid, with a recent Japan grid blackout analysis underscoring these challenges. But there are plans for a total of 4,000MW of offshore wind power capacity, including projects under feasibility studies.

J-Power set up a renewable energy division in June to look for opportunities to expand into wind and geothermal energy in Japan, and efforts like a Japan hydrogen energy system are emerging to support decarbonization. Kansai Electric also seeks know-how for increasing its reliance on renewable energy, even as it hurries to restart idled nuclear reactors.

They are not the only Japanese investors is in this field. In Asia, trading house Marubeni will invest in a Taiwanese venture with plans for a 600MW offshore wind farm.

Toronto Hydro Storm Outages continue after strong winds and heavy rain, with crews restoring power, clearing debris and downed lines. Safety alerts and real-time updates guide affected neighborhoods via website and social media.

Key Points

Toronto Hydro Storm Outages are weather-related power cuts; crews restore service safely and share public updates.

✅ Crews prioritize areas with severe damage and limited access

✅ Report downed power lines; keep a safe distance

✅ Check website and social media for restoration updates

In the aftermath of a powerful spring storm that swept through Toronto on Tuesday, approximately 400 customers remain without power as of Sunday. The storm, which brought strong winds and heavy rain that caused severe flooding in some areas, led to significant damage across the city, including downed trees and power lines. Toronto Hydro crews have been working tirelessly to restore service, similar to efforts by Sudbury Hydro crews in Northern Ontario, focusing on areas with the most severe damage. While many customers have had their power restored, the remaining outages are concentrated in neighborhoods where access is challenging due to debris and fallen infrastructure.

Toronto Hydro has assured residents that restoration efforts are ongoing and that they are prioritizing safety and efficiency, in step with recovery from damaging storms in Ontario across the province. The utility company has urged residents to report any downed power lines and to avoid approaching them, as they may still be live and dangerous, and notes that utilities sometimes rely on mutual aid deployments to speed restoration in large-scale events. Additionally, Toronto Hydro has been providing updates through their website and social media channels, keeping the public informed about the status of power restoration in affected areas.

The storm's impact has also led to disruptions in other services, and power outages in London disrupted morning routines for thousands earlier in the week. Some public transportation routes experienced delays due to debris on tracks, and several schools in the affected areas were temporarily closed. City officials are coordinating with various agencies to address these issues and ensure that services return to normal as quickly as possible, even as Quebec contends with widespread power outages after severe windstorms.

Residents are advised to stay updated on the situation through official channels and to exercise caution when traveling in storm-affected areas. Toronto Hydro continues to work diligently to restore power to all customers and appreciates the public's patience during this challenging time, a challenge echoed when Texas utilities struggled to restore power during Hurricane Harvey.

Global Electricity Emissions Decline highlights a 2% drop as coal power falls, while wind and solar surge. EU and US decarbonize faster; China expands coal and gas, challenging Paris Agreement climate targets.

Key Points

A 2% annual fall in power-sector CO2, led by less coal and rising wind and solar in the EU and US.

✅ Coal generation fell 3% globally despite China growth

✅ EU and US cut coal; wind and solar up 15% worldwide

✅ Gas gains in US; rapid renewables rollout needed for targets

Carbon emissions from the global electricity system fell by 2% last year, the biggest drop in almost 30 years, as countries began to turn their backs on coal-fired power plants.

A new report on the world’s electricity generation revealed the steepest cut in carbon emissions since 1990, with IEA data indicating global totals flatlined in 2019 as the US and the EU turned to cleaner energy sources.

Overall, power from coal plants fell by 3% last year, even as China’s reliance on coal plants climbed for another year to make up half the world’s coal generation for the first time.

Coal generation in the US and Europe has halved since 2007, and last year collapsed by almost a quarter in the EU and by 16% in the US.

The report from climate thinktank Ember, formerly Sandbag, warned that the dent in the world’s coal-fired electricity generation relied on many one-off factors, including milder winters across many countries.

“Progress is being made on reducing coal generation, but nothing like with the urgency needed to limit climate change,” the report said.

Dave Jones, the lead author of the report, said governments must dramatically accelerate the global energy transition so that global coal generation collapses throughout the 2020s.

“To switch from coal into gas is just swapping one fossil fuel for another. The cheapest and quickest way to end coal generation is through a rapid rollout of carbon-free electricity such as wind and solar,” he said.

“But without concerted policymaker efforts to boost wind and solar, we will fail to meet climate targets. China’s growth in coal, and to some extent gas, is alarming but the answers are all there.”

The EU has made the fastest progress towards replacing coal with wind and solar power, while the US has increased its reliance on gas as Wall Street’s energy strategy shifted following its shale boom in recent years.

The report revealed that renewable wind and solar power rose by 15% in 2019 to make up 8% of the world’s electricity.

In the EU, wind and solar power made up almost a fifth of the electricity generated last year, and Europe’s oil majors are turning electric as the bloc stayed ahead of the US which relied on these renewable sources for 11% of its electricity. In China and India, renewable energy made up 8% and 9% of the electricity system, respectively.

To meet the Paris climate goals, the world needs to record a compound growth rate of 15% for wind and solar generation every year – which will require “a colossal effort”, the report warned.

The electricity generation report was published as a separate piece of research claimed that 38 out of 75 of the world’s largest asset managers are stalling on taking action on environmental, social and governance (ESG) issues, and amid investor pressure on utilities to release climate reports.

The latest ranking by Asset Owners Disclosure Project, a scheme managed by the investment campaign group ShareAction, found that the 38 asset managers have weak or nonexistent policy commitments and fail to account for their real-world impacts across their mainstream assets.

The survey also claimed that the investment managers often lack appropriate engagement and escalation processes on climate change, human rights and biodiversity.

Scores were based on a survey of activities in responsible investment governance, climate change, human rights, and biodiversity and ranged between AAA to E. Not a single asset manager was granted an AAA or AA rating, the top two scores available.

Felix Nagrawala, ShareAction analyst, said: “While many in the industry are eager to promote their ESG credentials, our analysis clearly indicates that few of the world’s largest asset managers can lay claim to having a truly sustainable approach across all their investments.”

ShareAction said the world’s six largest asset managers – including BlackRock (rated D), State Street (D) and Vanguard (E) – were among the worst performers.

Vanguard said it was committed to companies making “appropriate disclosures on governance, strategy and performance on relevant ESG risks”. BlackRock and State Street did not respond to a request for comment.
