Longest Lightning Flash Record confirmed by WMO: a 477.2-mile megaflash spanning Mississippi, Louisiana, and Texas, detected by satellite sensors, highlighting Great Plains supercell storms, lightning safety, and extreme weather monitoring advancements.

 

Key Points

It is the WMO-verified 477.2-mile megaflash across MS, LA, and TX, detected via satellites.

✅ Spanned 477.2 miles across Mississippi, Louisiana, and Texas

✅ Verified by WMO using space-based lightning detection

✅ Occurs in megaflash-prone regions like the U.S. Great Plains

 

An almost 500-mile long bolt of lightning that lit up the sky across three US states has set a new world record for longest flash, scientists have confirmed.

The lightning bolt, extended a total of 477.2 miles (768 km) and spread across Mississippi, Louisiana, and Texas.

The previous record was 440.6 miles (709 km) and recorded in Brazil in 2018.

Lightning rarely extends over 10 miles and usually lasts under a second, yet utilities plan for severe weather when building long-distance lines such as the TransWest Express transmission project to enhance reliability.

Another lightning flash recorded in 2020 - in Uruguay and Argentina - has also set a new record for duration at 17.1 seconds. The previous record was 16.7 seconds.

"These are extraordinary records from lightning flash events," Professor Randall Cerveny, the WMO's rapporteur of weather and climate extremes, said.

According to the WMO, both records took place in areas prone to intense storms that produce 'megaflashes', namely the Great Plains region of the United States and the La Plata basin of South America's southern cone, where utilities adapting to climate change is an increasing priority.

Professor Cerveny added that greater extremes are likely to exist and are likely to be recorded in the future thanks to advances in space-based lightning detection technology.

The WMO warned that lightning was a hazard and urged people in both regions and around the world to take caution during storms, which can lead to extensive disruptions like the Tennessee power outages reported after severe weather.

"These extremely large and long-duration lightning events were not isolated but happened during active thunderstorms," lightning specialist Ron Holle said in a WMO statement.

"Any time there is thunder heard, it is time to reach a lightning-safe place".

Previously accepted WMO 'lightning extremes' include a 1975 incident in which 21 people were killed by a single flash of a lightning as they huddled inside a tent in Zimbabwe, and modern events show how dangerous weather can also cut electricity for days, as with the Hong Kong typhoon outages that affected families.

In another incident, 469 people were killed when lightning struck the Egyptian town of Dronka in 1994, causing burning oil to flood the town, and major incidents can also disrupt infrastructure, as seen during the LA power outage following a substation fire.

The WMO notes that the only lightning-safe locations are "substantial" buildings with wiring and plumbing, and dedicated lightning protection training helps reinforce these guidelines, rather than structures such as bus stops or those found at beaches.

Fully enclosed metal-topped vehicles are also considered reliably safe, and regional storm safety tips offer additional guidance.

California Public Utilities Commission sides with community energy program over SDG&E

CPUC Decision on San Diego Community Power directs SDG&E to use updated forecasts, stabilizing electricity rates for CCA customers and supporting clean energy in San Diego with accurate rate forecasting and reduced volatility.

 

Key Points

A CPUC ruling directing SDG&E to use updated forecasts to ensure accurate, stable CCA rates and limit volatility.

✅ Uses 2021 sales forecasts for rate setting

✅ Aims to prevent undercollection and bill spikes

✅ Levels changes across customer classes

 

The California Public Utilities Commission on Thursday sided with the soon-to-launch San Diego community energy program in a dispute it had with San Diego Gas & Electric.

San Diego Community Power — which will begin to purchase power for customers in San Diego, Chula Vista, La Mesa, Encinitas and Imperial Beach later this year — had complained to the commission that data SDG&E intended to use to calculate rates, including community choice exit fees that could make the new energy program less attractive to prospective customers.

SDG&E argued it was using numbers it was authorized to employ as part of a general rate case amid a potential rate structure revamp that is still being considered by the commission.

But in a 4-0 vote, the commission, or CPUC, sided with San Diego Community Power and directed SDG&E to use an updated forecast for energy sales.

"This was not an easy decision," said CPUC president Marybel Batjer at the meeting, held remotely due to COVID-19 restrictions. "In my mind, this outcome best accounts for the shifting realities ... in the San Diego area while minimizing the impact on ratepayers during these difficult financial times."

In filings to the commission, SDG&E predicted a rate decrease of 12.35 percent in the coming year. While that appears to be good news for customers, Californians still face soaring electricity prices statewide, Commissioner Martha Guzman Aceves said the data set SDG&E wanted to use would lead to an undercollection of $150 million to $260 million.

That would result in rates that would be "artificially low," Guzman Aceves said, and rates "would inevitably go up quite a bit after the undercollection was addressed."

San Diego Community Power, or SDCP, said the temporary reduction would make its rates less attractive than SDG&E's, especially amid SDG&E's minimum charge proposal affecting low-usage customers, just as it is about to begin serving customers. SDCP's board members wrote an open letter last month to the commission, accusing the utility of "willful manipulation of data."

Working with an administrative law judge at the CPUC, Guzman Aceves authored a proposal requiring SDG&E to use numbers based on 2021 forecasts, as regulators simultaneously weigh whether the state needs more power plants to ensure reliability. The utility argued that could result in an increase of "roughly 40 percent" for medium and large commercial and industrial customers this year.

To help reduce potential volatility, Guzman Aceves, SDCP and other community energy supporters called for using a formula that would average out changes in rates across customer classes amid debates over income-based utility charges statewide. That's what the commissioners OK'd Thursday.

"It is essential that customer commodity rates be as accurate as we can possibly get them to avoid undercollections," said Commissioner Genevieve Shiroma.

San Diego Community Power is one of 23 community choice aggregation, or CCA, energy programs that have launched in California in the past decade.

CCAs compete with traditional power companies amid California's evolving power competition landscape, in one important role — purchasing power for a given community. They were created to boost the use of cleaner energy sources, such as wind and solar, at rates equal to or lower than investor-owned utilities.

However, CCAs do not replace utilities because the incumbent power companies still perform all of the tasks outside of power purchasing, such as transmission and distribution of energy and customer billing.

When a CCA is formed, California rules stipulate the utility customers in that area are automatically enrolled in the CCA. If customers prefer to stay with their previous power company, they can opt out of joining the CCA.

The shift of customers from SDG&E to San Diego Community Power is expected to be large. The total number of accounts for SDCP is expected to be 770,000, which would make it the second-largest CCA in the state. That's why SDCP considered Thursday's CPUC decision to be so important.

"At a time when customers are choosing between sticking with San Diego Gas & Electric and migrating to a CCA, we want them to have accurate bill information," said Commissioner Clifford Rechtschaffen.

"SDCP is very happy with today's CPUC decision, and that the commissioners shared our goal of limiting rate volatility for businesses and families in the region," said SDCP interim CEO Bill Carnahan. "This is definitely a win for accurate rate forecasting, and our mutual customers, and we look forward to working with SDG&E on next steps."

In an email, SDG&E spokeswoman Helen Gao said, "We are committed to continuing to work collaboratively with local Community Choice Aggregation programs to support their successful launch in 2021 and ensure that our mutual customers receive excellent customer service."

San Diego Community Power's case before the CPUC was joined by the California Community Choice Association, a trade group advocating for CCAs, and the Clean Energy Alliance — the North County-based CCA representing Del Mar, Solana Beach and Carlsbad that is scheduled to launch this summer.

SDCP will begin its rollout this year, folding in about 71,000 municipal, commercial and industrial accounts. The bulk of its roughly 700,000 residential accounts is expected to come in January 2022.

Costa Rica hits record electricity generation from 99% renewable sources

Costa Rica Renewable Energy Record highlights 99.99% clean power in May 2019, driven by hydropower, wind, solar, geothermal, and biomass, enabling ICE REM electricity exports and reduced rates from optimized generation totaling 984.19 GWh.

 

Key Points

May 2019 benchmark: Costa Rica generated 99.99% of 984.19 GWh from renewables, shifting from imports to regional exports.

✅ 99.99% renewable share across hydro, wind, solar, geothermal, biomass

✅ 984.19 GWh generated; ICE suspended imports and exported via REM

✅ Geothermal output increased to offset dry-season hydropower variability

 

During the whole month of May 2019, Costa Rica generated a total of 984.19 gigawatt hours of electricity, the highest in the country’s history. What makes this feat even more impressive is the fact that 99.99% of this energy came from a portfolio of renewable sources such as hydropower, wind, biomass, solar, and geothermal.

With such a high generation rate, the state power company Instituto Costariccense de Electricidad (ICE) were able to suspend energy imports from the first week of May and shifted to exports, while U.S. renewable electricity surpassed coal in 2022 domestically. To date, the power company continues to sell electricity to the Regional Electricity Market (REM) which generates revenues and is likely to reduce local electricity rates, a trend echoed in places like Idaho where a vast majority of electricity comes from renewables.

The record-breaking power generation was made possible by optimization of the country’s renewable sources, much as U.S. wind capacity surpassed hydro capacity at the end of 2016 to reshape portfolios. As the period coincided with the tail end of the dry season, the geothermal quota had to be increased.

Costa Rica remains a leader in renewable power generation, whereas U.S. wind generation has become the most-used renewable source in recent years. In 2015, more than 98% of the country’s electrical generation came from renewable sources, while U.S. renewables hit a record 28% in April in one recent benchmark. Through the years, this figure has remained fairly constant despite dry bouts caused by the El Niño phenomenon, and U.S. solar generation also continued to rise.

Multi-billion-dollar hydro generation project proposed for Meaford military base

Meaford Pumped Storage Project aims to balance the grid with hydro-electric generation, a hilltop reservoir, and transmission lines near Georgian Bay, pending environmental assessment, permitting, and federal review of impacts on fish and drinking water.

 

Key Points

TC Energy proposal to pump water uphill off-peak and generate 1,000 MW at peak, pending studies and approvals.

✅ Balances grid by storing off-peak energy and generating at peak.

✅ Requires reservoir, break wall, transmission lines, generating station.

✅ Environmental studies and federal review underway before approvals.

 

Plans for a $3.3 billion hydro-electric project in Meaford are still in the early study stages, but some residents have concerns about what it might mean for the environment, as past Site C stability issues have illustrated for large hydro projects.

A one-year permit was granted for TC Energy Corporation (TC Energy) to begin studies on the proposed location back in May, and cross-border projects like the New England Clean Power Link require federal permits as well to proceed. Local municipalities were informed of the project in June.

TC Energy is proposing to have a pumped storage project at the 4th Canadian Division Training (4CDTC) Meaford property, which is on federal lands.

A letter sent to local municipalities explains that the plan is to balance supply and demand on the electrical grid by pumping water uphill during off-peak hours. It would then release the water back into Georgian Bay during peak periods, generating up to 1,000 megawatts of electricity.

The project is expected to create 800 jobs over four years of construction, in addition to long-term operational positions.


 

According to the company's website, the proposed pump station would require a large reservoir on the military base, a generating station, transmission lines infrastructure, and a break wall 850 metres from shore.

Some residents fear the project will threaten the bay and the fish, echoing Site C dam concerns shared with northerners, and the region's drinking water.

Meaford's mayor says the town has no jurisdiction on federal lands, but that a list of concerns has been forwarded to the company, while Ontario First Nations have urged government action on urgent transmission needs elsewhere.

TC Energy will tackle preliminary engineering and environmental studies to determine the feasibility of the proposed location, which could take up to two years.

Once the assessments are done, they need to be presented to the government for further review and approval, as seen when Ottawa's Site C stance left work paused pending a treaty rights challenge.

TC Energy's website states that the company anticipates construction to begin in 2022 if it gets all the go-ahead, with the plant to begin operations four years later.

Input from residents is being collected until April 2020, similar to when the National Energy Board heard oral traditional evidence on the Manitoba-Minnesota transmission line.

Severe heat: 5 electricity blackout risks facing the entire U.S., not just Texas

Texas power grid highlights ERCOT reliability strains from extreme heat, climate change, and low wind, as natural gas and renewables balance tight capacity amid EV charging growth, heat pumps, and blackout risk across the U.S.

 

Key Points

Texas power grid is ERCOT-run and isolated, balancing natural gas and wind amid extreme weather and electrification.

✅ Isolated from other U.S. grids, limited import support

✅ Vulnerable to extreme heat, winter storms, low wind

✅ Demand growth from EVs and heat pumps stresses capacity

 

Texas has a unique state-run power grid facing a Texas grid crisis that has raised concerns, but its issues with extreme weather, and balancing natural gas and wind, hold lessons for an entire U.S. at risk for power outages from climate change.

Grid operator the Electric Reliability Council of Texas, or ERCOT, which has drawn criticism from Elon Musk recently, called on consumers to voluntarily reduce power use on Monday when dangerous heat gripped America’s second-most populous state.

The action paid off as the Texas grid avoided blackouts — and a repeat of its winter crisis — despite record or near-record temperatures that depleted electric supplies amid a broader supply-chain crisis affecting utilities this summer, and risked lost power to more than 26 million customers. ERCOT later on Monday lifted the call for conservation.

For sure, it’s a unique situation, as the state-run power grid system runs outside the main U.S. grids. Still, all Americans can learn from Texas about the fragility of a national power grid that is expected to be challenged more frequently by hot and cold weather extremes brought on by climate change, including potential reliability improvements policymakers are weighing.

The grid will also be tested by increased demand to power electric vehicles (EVs) and conversions to electric heat pumps — all as part of a transition to a “greener” future.

 

Why is Texas different?
ERCOT, the main, but not only, Texas grid, is unique in its state-run, and not regional, format used by the rest of the country. Because it’s an energy-rich state, Texas has been able to set power prices below those seen in other parts of the country, and its independence gives it more pricing authority, while lawmakers consider market reforms to avoid blackouts. But during unusual strain on the system, such as more people blasting their air conditioners longer to combat a record heat wave, it also has no where else to turn.

A lethal winter power shortage in February 2021, during a Texas winter storm that left many without power and water, notoriously put the state and its independent utility in the spotlight when ERCOT failed to keep residents warm and pipes from bursting. Texas’s 2021 outage left more than 200 people dead and rang up $20 billion in damage. Fossil-fuel CL00, 0.80% backers pointed to the rising use of intermittent wind power, which generates 23% of Texas’s electricity. Others said natural-gas equipment was frozen under the extreme conditions.

This week, ERCOT is asking for voluntary conservation between 2 p.m. and 8 p.m. local time daily due to record high electricity demand from the projected heat wave, and also because of low wind. ERCOT said current projections show wind generation coming in at less than 10% of capacity. ERCOT stressed that no systemwide outages are expected, and Gov. Greg Abbott has touted grid readiness heading into fall, but it was acting preemptively.

A report late last year from the North American Electric Reliability Corp. (NERC) said the Texas system without upgrades could see a power shortfall of 37% in extreme winter conditions. NERC’s outlook suggested the state and ERCOT isn’t prepared for a repeat of weather extremes.

Ontario's Clean Electricity Regulations: Paving the Way for a Greener Future

Ontario Clean Electricity Regulations accelerate renewable energy adoption, drive emissions reduction, and modernize the smart grid with energy storage, efficiency targets, and reliability upgrades to support decarbonization and a stable power system for Ontario.

 

Key Points

Standards to cut emissions, grow renewables, improve efficiency, and modernize the grid with storage and smart systems.

✅ Phases down fossil generation and invests in storage.

✅ Sets utility efficiency targets to curb demand growth.

✅ Upgrades to smart grid for reliability and resiliency.

 

Ontario has taken a significant step forward in its energy transition with the introduction of new clean electricity regulations. These regulations, complementing federal Clean Electricity Regulations, aim to reduce carbon emissions, promote sustainable energy sources, and ensure a cleaner, more reliable electricity grid for future generations. This article explores the motivations behind these regulations, the strategies being implemented, and the expected impacts on Ontario’s energy landscape.

The Need for Clean Electricity

Ontario, like many regions around the world, is grappling with the effects of climate change, including more frequent and severe weather events. In response, the province has set ambitious targets to reduce greenhouse gas emissions and increase the use of renewable energy sources, reflecting trends seen in Alberta’s path to clean electricity across Canada. The electricity sector plays a central role in this transition, as it is responsible for a significant portion of the province’s carbon footprint.

For years, Ontario has been moving away from coal as a source of electricity generation, and now, with the introduction of these new regulations, the province is taking a step further in decarbonizing its grid, including its largest competitive energy procurement to date. By setting clear goals and standards for clean electricity, the province hopes to meet its environmental targets while ensuring a stable and affordable energy supply for all Ontarians.

Key Aspects of the New Regulations

The regulations focus on encouraging the use of renewable energy sources such as wind, solar, hydroelectric, and geothermal power. One of the key elements of the plan is the gradual phase-out of fossil fuel-based energy sources. This shift is expected to be accompanied by greater investments in energy storage solutions, including grid batteries, to address the intermittency issues often associated with renewable energy sources.

Ontario’s new regulations also emphasize the importance of energy efficiency in reducing overall demand. As part of this initiative, utilities and energy providers will be required to meet strict energy-saving targets and participate in new electricity auctions designed to reduce costs, ensuring that both consumers and businesses are incentivized to use energy more efficiently.

In addition, the regulations promote technological innovation in the electricity sector. By supporting the development of smart grids, energy storage technologies, and advanced power management systems, Ontario is positioning itself to become a leader in the global energy transition.

Impact on the Economy and Jobs

One of the anticipated benefits of the clean electricity regulations is their positive impact on Ontario’s economy. As the province invests in renewable energy infrastructure and clean technologies, new job opportunities are expected to arise in industries such as manufacturing, construction, and research and development. These regulations also encourage innovation in energy services, which could lead to the growth of new companies and industries, while easing pressures on industrial ratepayers through complementary measures.

Furthermore, the transition to cleaner energy is expected to reduce the long-term costs associated with climate change. By investing in sustainable energy solutions now, Ontario will help mitigate the financial burdens of environmental damage and extreme weather events in the future.

Challenges and Concerns

While the new regulations have been widely praised for their environmental benefits, they are not without their challenges. One of the primary concerns is the potential cost to consumers, and some Ontario hydro policy critique has called for revisiting legacy pricing approaches to improve affordability. While renewable energy sources have become more affordable over the years, transitioning from fossil fuels could still result in higher electricity prices in the short term. Additionally, the implementation of new technologies, such as smart grids and energy storage, will require substantial upfront investment.

Moreover, the intermittency of renewable energy generation poses a challenge to grid stability. Ontario’s electricity grid must be able to adapt to fluctuations in energy supply as more variable renewable sources come online. This challenge will require significant upgrades to the grid infrastructure and the integration of storage solutions to ensure reliable energy delivery.

The Road Ahead

Ontario’s clean electricity regulations represent an important step in the province’s commitment to combating climate change and transitioning to a sustainable, low-carbon economy. While there are challenges to overcome, the benefits of cleaner air, reduced emissions, and a more resilient energy system will be felt for generations to come. As the province continues to innovate and lead in the energy sector, Ontario is positioning itself to thrive in the green economy of the future.

Romania moves to terminate talks with Chinese partner in nuke project

Romania Ends CGN Cernavoda Nuclear Deal, as Nuclearelectrica moves to terminate negotiations on reactors 3 and 4, citing the EU Green Deal, US partnership, NATO, and a shift to alternative nuclear capacity options.

 

Key Points

Romania orders Nuclearelectrica to end CGN talks on Cernavoda units 3-4 and pursue alternative nuclear options.

✅ Negotiations on Cernavoda units 3-4 to be formally terminated

✅ EU Green Deal and US partnership cited over security concerns

✅ Board to draft strategies for new domestic nuclear capacity

 

Romania's government has mandated the managing board of local nuclear power producer Nuclearelectrica to initiate procedures for terminating negotiations with China General Nuclear Power Group (CGN) on building two new reactors at the Cernavoda nuclear power plant, where IAEA safety reports continue to shape operations.

The government also mandated the managing board to analyse and draw up strategic options on the construction of new electricity generation capacities from nuclear sources, as other countries such as India take steps to get nuclear back on track in response to demand.

The company will negotiate the termination of the agreement signed in 2015 for developing and operating units 3 and 4 at Cernavoda, even as Germany turns away from nuclear within the European landscape. 

At the end of last month, Economy Minister Virgil Popescu said that the collaboration with the Chinese company couldn't continue as it has yielded no results in seven years, despite China's nuclear program expanding steadily elsewhere.

"We have a strategic partnership with the US, and we hold on to it, we respect our partners. We are members of the EU and Nato, even as Germany's final reactor closures unfold in Europe. Aside from that, I think that seven years since this collaboration with the Chinese company began is enough to realise that we can't move on," Popescu said at that time.

Liberal Prime Minister Ludovic Orban announced in January that the government would exit the deal with its Chinese partner. He invoked the European Union's Green Deal rather than security issues or cost concerns circulated previously as the main reason behind a potential end of the deal with CGN to expand Romania's only nuclear power plant, amid concerns that Europe is losing nuclear power when it needs energy.

In August last year, the US included CGN on a blacklist for allegedly trying to get nuclear technology from the US to be used for military purposes in China, even as nuclear cooperation with Cambodia expands in the region.
