Carol and Ed Soph's electric meter runs backward.

Not all the time, but enough to drastically cut their home energy bill.

The Sophs installed 16 solar panels on the roof of their northeast Denton home last year. Energy from the sun powers their home during the daytime. Any excess power goes onto the city's power grid, and the Sophs' meter arrow turns around.

"We're a power company here," Mrs. Soph said with a laugh.

When the system isn't producing energy, such as at night, the city's electric grid powers the Sophs' 2,200-square-foot home.

Their 2,500-watt system is among the first to hook into the Denton Municipal Electric grid. The couple hopes other people follow suit, as rising energy costs and global-warming concerns have many searching for alternatives to coal- and gas-powered electricity.

"There's no moving parts, and every time the sun comes up, our electricity is delivered," Mr. Soph said.

"It's free delivery," Mrs. Soph added. "The sun is free."

But the solar panels weren't.

They cost $27,000.

That's enough to put off many potential customers, said Jim Duncan, president of North Texas Renewable Energy Inc., which installs solar power systems.

Mr. Duncan said he's getting more calls than ever from people fed up with high electricity rates. But installations have remained flat, he said.

"It's expensive," Mr. Duncan said. "But it is an investment."

That's how the Sophs are looking at it. They paid for the solar panels with money meant for their retirement.

"Since we're going to retire here, it's going to pay off, and if we were to sell the house, we wouldn't lose any money on it," said Mrs. Soph, a community volunteer. "I just looked at those two things. By multiplying this [savings] out, it's better than if I invested this in a CD."

They got the idea from watching a home improvement show featuring the makeover of a 1940s-era Austin home into a modern "green" abode, complete with solar panels.

The idea intrigued the Sophs, founding members of local environmental watchdog group Citizens for Healthy Growth. They called a person featured on the show, who put them in touch with Mr. Duncan.

The system generates more than half of the Sophs' electricity. From February through April, their electric bills were about $370 lower than the same period last year. They credit the solar panels along with other efforts to reduce their use of electricity, including switching to low-energy light bulbs and installing a timer on their water heater.

When residents install solar panels, it only benefits the city, said Lisa Lemons, a spokeswoman for Denton Municipal Electric.

"Any excess energy these PV [photovoltaic] systems generate means that much less that DME buys from fossil fuel sources," Ms. Lemons said in an e-mail.

Unlike some cities, though, Denton doesn't offer financial incentives for installing the systems. Ms. Lemons said an incentives program is under review for fiscal 2009.

EDP Plans to Reject $10.9 Billion-China Three Gorges Bid

EDP Takeover Bid Rejection signals pushback on China Three Gorges' acquisition bid, as investors, shareholders, and analysts cite low premium, valuation concerns, and strategic renewables assets across Portugal, the US, Brazil, and Europe utilities.

 

Key Points

EDP's board views China Three Gorges' 3.26 euro per share offer as too low, citing valuation and renewables exposure.

✅ Bid premium 4.8% above close seen as inadequate.

✅ Stock surged above offer; market expects higher price.

✅ Advisors UBS and Morgan Stanley guiding EDP.

 

EDP-Energias de Portugal SA is poised to reject a 9.1 billion euro ($10.9 billion) takeover offer from China Three Gorges Corp. on the grounds that it undervalues Portugal’s biggest energy company, according to people with knowledge of the matter.

The board of EDP, which may meet as early as this week, views the current bid of 3.26 euros a share as too low as it indicates a premium of 4.8 percent over Friday’s close, said the people, asking not to be identified because the discussions are private. EDP is also working with advisers including UBS Group AG and Morgan Stanley on the potential deal, they said.

Representatives for EDP, UBS and Morgan Stanley declined to comment. Representatives for Three Gorges didn’t immediately respond to requests for comment.

#google#

Shares of EDP surged the most in a decade to above the bid level on Monday, signaling that investors expect the Chinese utility, which is its biggest investor, to sweeten the offer to gain full control. For Three Gorges, which spent two decades building a hydro-power plant spanning China’s Yangtze River, the deal would bolster its efforts to expand abroad and give it deeper access to markets in Europe, the U.S. and Brazil.

China’s biggest renewable-energy developer already is the largest shareholder of EDP with a 23 percent stake and now is seeking more than 50 percent. While the government in Lisbon has indicated it’s comfortable with the Chinese offer, EDF electricity price deal illustrates policy dynamics in the region and it holds out little incentive for shareholders to tender their stock.

 

Stock Jumps

Shares of EDP rose 9.3 percent to 3.40 euros in Lisbon on Monday, even as rolling back European electricity prices remains challenging, after earlier jumping by the most since October 2008.

“We believe the price offered is too low for China Three Gorges to achieve full control of a vehicle that provides, among other things, a strategic footprint into U.S. renewables,” Javier Garrido, an analyst at JPMorgan Chase & Co., said in a note. “We expect management and minorities to claim a higher price.”

The offer adds to a wave of investments China has made overseas, both to earn a yield on its cash and to gain expertise in industries ranging from energy to telecommunications and transport. Concern about those deals has been mounting in the U.S. regulatory arena recently. European Union governments have been divided in their response, with Portugal among those most supportive of inward investment.

“China Three Gorges is an ambitious company, with expansion already in international hydro, Chinese onshore wind and floating solar, and European offshore wind,” said Angus McCrone, a senior analyst at Bloomberg New Energy Finance in London. “It may have to do better on bid price than the 5 percent premium so far offered for EDP.”

 

Fortum’s Troubles

The low premium offered by Three Gorges echoes the struggle Fortum Oyj had in winning over investors in its bid for Uniper SE last year, while North American deals such as Hydro One’s Avista bid faced customer backlash as well, highlighting parallels. The Finnish utility offered 8 billion euros to buy out the remainder of Uniper in September, immediately sending shares of the German power generator above the offer prices. At least for now, Fortum has settled for a 47 percent stake it bought in Uniper from EON SE, and most other shareholders decided to keep their stake.

The EDP transaction would advance a wave of consolidation among Europe’s leading utilities, which are acquiring assets and development skills in renewables as governments across the region crack down on pollution. EDP is one of Europe’s leading developers of renewable energy, building mainly wind farms and hydro plants, and has expanded in markets including Brazil and the U.S. electrification market.

Four Facts about Covid and U.S. Electricity Consumption

COVID-19 Impact on U.S. Electricity Consumption shows commercial and industrial demand dropped as residential use rose, with flattened peak loads, weekday-weekend convergence, Texas hourly data, and energy demand as a real-time economic indicator.

 

Key Points

It reduced commercial and industrial demand while raising residential use, shifting peaks and weekday patterns.

✅ Commercial electricity down 12%; industrial down 14% in Q2 2020

✅ Residential use up 10% amid work-from-home and lockdowns

✅ Peaks flattened; weekday-weekend loads converged in Texas

 

This is an important turning point for the United States. We have a long road ahead. But one of the reasons I’m optimistic about Biden-Harris is that we will once again have an administration that believes in science.

To embrace this return to science, I want to write today about a fascinating new working paper by Tufts economist Steve Cicala.

Professor Cicala has been studying the effect of Covid on electricity consumption since back in March, when the Wall Street Journal picked up his work documenting an 18% decrease in electricity consumption in Italy.

The new work, focused on the United States, is particularly compelling because it uses data that allows him to distinguish between residential, commercial, and industrial sectors, against a backdrop of declining U.S. electricity sales over recent years.

Without further ado, here are four facts he uncovers about Covid and U.S. electricity demand during COVID-19 and consumption.

 

Fact #1: Firms Are Using Less
U.S. commercial electricity consumption fell 12% during the second quarter of 2020. U.S. industrial electricity consumption fell 14% over the same period.

This makes sense. The second quarter was by some measures, the worst quarter for the U.S. economy in over 145 years!

Economic activity shrank. Schools closed. Offices closed. Factories closed. Restaurants closed. Malls closed. Even health care offices closed as patients delayed going to the dentist and other routine care. All this means less heating and cooling, less lighting, less refrigeration, less power for computers and other office equipment, less everything.

The decrease in the industrial sector is a little more surprising. My impression had been that the industrial sector had not fallen as far as commercial, but amid broader disruptions in coal and nuclear power that strained parts of the energy economy, the patterns for both sectors are quite similar with the decline peaking in May and then partially rebounding by July. The paper also shows that areas with higher unemployment rates experienced larger declines in both sectors.

 

Fact #2: Households Are Using More
While firms are using less, households are using more. U.S. residential electricity consumption increased 10% during the second quarter of 2020. Consumption surged during March, April, and May, a reflection of the lockdown lifestyle many adopted, and then leveled off in June and July – with much less of the rebound observed on the commercial/industrial side.

This pattern makes sense, too. In Professor Cicala’s words, “people are spending an inordinate amount of time at home”. Many of us switched over to working from home almost immediately, and haven’t looked back. This means more air conditioning, more running the dishwasher, more CNN (especially last week), more Zoom, and so on.

The paper also examines the correlates of the decline. Areas in the U.S. where more people can work from home experienced larger increases. Unemployment rates, however, are almost completely uncorrelated with the increase.

 

Fact #3: Firms are Less Peaky
The paper next turns to a novel dataset from Texas, where Texas grid reliability is under active discussion, that makes it possible to measure hourly electricity consumption by sector.

As the figure above illustrates, the biggest declines in commercial/industrial electricity consumption have occurred Monday through Friday between 9AM and 5PM.

The dashed line shows the pattern during 2019. Notice the large spikes in electricity consumption during business hours. The solid line shows the pattern during 2020. Much smaller spikes during business hours.

 

Fact #4: Everyday is Like Sunday
Finally, we have what I would like to nominate as the “Energy Figure of the Year”.

Again, start with the pattern for 2019, reflected by the dashed line. Prior to Covid, Texas households used a lot more electricity on Saturdays and Sundays.

Then along comes Covid, and turned every day into the weekend. Residential electricity consumption in Texas during business hours Monday-Friday is up 16%(!).

In the pattern for 2020, it isn’t easy to distinguish weekends from weekdays. If you feel like weekdays and weekends are becoming a big blur – you are not alone.

 

Conclusion
Researchers are increasingly thinking about electricity consumption as a real-time indicator of economic activity, even as flat electricity demand complicates utility planning and investment. This is an intriguing idea, but Professor Cicala’s new paper shows that it is important to look sector-by-sector.

While commercial and industrial consumption indeed seem to measure the strength of an economy, residential consumption has been sharply countercylical – increasing exactly when people are not at work and not at school.

These large changes in behavior are specific to the pandemic. Still, with the increased blurring of home and non-home activities we may look back on 2020 as a key turning point in how we think about these three sectors of the economy.

More broadly, Professor Cicala’s paper highlights the value of social science research. We need facts, data, and yes, science, if we are to understand the economy and craft effective policies on energy insecurity and shut-offs as well.

Biden administration pushes to revitalize coal communities with clean energy projects

Coal-to-Clean Energy Hubs leverage Bipartisan Infrastructure Law and Inflation Reduction Act funding to repurpose mine lands with microgrids, advanced nuclear, carbon capture, and rare earth processing, boosting energy security, jobs, and grid modernization.

 

Key Points

They are federal projects converting coal communities and mine lands into clean energy hubs, repurposing infrastructure.

✅ DOE demos on mine lands: microgrids, nuclear, carbon capture.

✅ Funding from BIL, CHIPS and IRA targets energy communities.

✅ Rare earths from coal waste bolster EV supply chains.

 

The Biden administration is channeling hundreds of millions of dollars in clean energy funding from recent legislation into its efforts to turn coal communities into clean energy hubs, the White House said.

The administration gave an update on its push across agencies to kick-start projects nationwide with funding Congress approved during Biden’s first two years in office. The effort includes $450 million from the Bipartisan Infrastructure Law that the Department of Energy will allocate to an array of new clean energy demonstration projects on former mine lands.

“These projects could focus on a range of technologies from microgrids to advanced nuclear to power plans with carbon capture,” Energy Secretary Jennifer Granholm said on a call with reporters Monday. “They’ll prove out the potential to reactivate or repurpose existing infrastructure like transmission lines and substations across an aging U.S. power grid, and these projects could spur new economic development in these communities.”

Among the projects the White House highlighted, it said $16 million from the infrastructure law will go to the University of North Dakota and West Virginia University to create design studies for the first-ever full-scale refinery facility in the U.S. that could extract and separate rare earth elements and minerals from coal mine waste streams. The materials are critical for electric vehicle-battery components that are currently heavily sourced from outside the U.S.

“Those efforts will pave the way toward building a first of its kind facility that produces essential materials for solar panels, wind turbines, EVs and more while cleaning up polluted land and water and creating good-paying jobs for local workers,” Granholm said.

Biden created an interagency working group focused on revitalizing coal-power communities through federal investments when he took office. In 2021, the group selected 25 priority areas ranging from West Virginia to Wyoming to focus on development, as high natural gas prices strengthened the case for clean electricity. There are nearly 18,000 identified mine sites across 1.5 million acres in the United States, according to the White House.

The massive effort fits into a broader Biden administration push to both fight climate change and support communities that have lost economic activity during a transition away from fossil fuel sources such as coal. While Biden’s most ambitious clean energy plans fell flat in Congress in the face of opposition from Republicans and some Democrats after the previous administration’s power plant overhaul, three major laws still unlocked funding for his administration to deploy.

Many of the initiatives are made possible through the Bipartisan Infrastructure Law, Chips and Science Act and the Inflation Reduction Act, even without a clean electricity standard on the books. The task force aims to make sure communities most affected by the changing energy landscape are taking maximum advantage of the federal benefits.

“Those new and expanded operations are coming to energy communities and creating good paying jobs,” Biden’s senior advisor for clean energy innovation and implementation John Podesta said on the call. “These laws can provide substantial federal support to energy communities like capping abandoned oil and gas wells, extracting critical minerals, building battery factories and launching demonstration projects in carbon capture or green hydrogen.”

The administration touted the potential benefits of the Inflation Reduction Act, a bill passed by Democrats to spur clean energy investments last year, even as early assessments show mixed results to date. At the time, U.S. consumers were dealing with decades-high inflation fueled in part by an energy crisis and high gas prices that drove debate — a point Republicans emphasized as the plan moved through Congress.

Deputy Treasury Secretary Wally Adeyemo said the Inflation Reduction Act aims to both “lower the deficit, as well as promote our energy security, lowering energy costs for consumers and combatting climate change.”

“As the Treasury works to implement the law, we’re focused on ensuring that all Americans benefit from the growth of the clean energy economy, particularly those who live in communities that have been dependent on the energy sector for job for a long time,” Adeyemo told reporters. “Economic growth and productivity are higher when all communities are able to reach their full potential.”

Toronto Cleans Up After Severe Flooding

Toronto Flood Cleanup details the citywide response to storm damage after heavy rain, stressing drainage system upgrades, emergency services, transit disruptions, infrastructure repair, financial aid, insurance claims, and climate resilience planning for future weather.

 

Key Points

Toronto Flood Cleanup is the city's flood response, restoring infrastructure, aiding residents, and upgrading drainage.

✅ Emergency services and public works lead debris removal.

✅ Repairs to roads, bridges, transit, and utilities underway.

✅ Aid, insurance claims, and drainage upgrades prioritized.

 

Toronto is grappling with significant cleanup efforts following severe storms that unleashed heavy rains and caused widespread flooding across the city. The storms, which hit the area over the past week, have left a trail of damage and disruption, prompting both immediate response measures and longer-term recovery plans.

The intense rainfall began with a powerful storm system that moved through southern Ontario, with Sudbury Hydro crews working to reconnect service as the system pressed toward the GTA, delivering an unprecedented volume of water in a short period. The resulting downpours overwhelmed the city's drainage systems, leading to severe flooding in multiple neighborhoods. Streets, basements, and parks were inundated, with many areas experiencing water levels not seen in recent memory.

Emergency services were quickly mobilized to address the immediate impact of the floods. Toronto’s Fire Services, along with other first responders and skilled utility teams, as Ontario recently sent 200 workers to Florida to help restore power, were deployed to assist residents affected by the rising waters. Rescue operations were carried out to help people trapped in their homes or vehicles, and temporary shelters were set up for those displaced by the flooding.

The storm's impact was felt across various sectors of the city. Public transportation services were disrupted, as strong gusts led to significant power outages in parts of the region, with numerous subway stations and bus routes affected by the high water levels. Major roads were closed due to flooding, causing significant traffic delays and affecting daily commutes for many residents. Local businesses also faced challenges, with some forced to close their doors as a result of the water damage.

The city's infrastructure bore the brunt of the storm's fury. Several key infrastructure components, including roads, bridges, and utilities, suffered damage. The city's water treatment plants and sewage systems were stressed by the volume of water, raising concerns about potential contamination and the need for extensive maintenance and repair work.

In the wake of the flooding, the Toronto Municipal Government has launched a comprehensive cleanup and recovery effort. The city's Public Works Department is spearheading the operation, focusing on clearing debris, repairing damaged infrastructure, and restoring essential services, as Hydro One crews restore power to hundreds of thousands across Ontario. Teams of workers are diligently addressing the damage to roads and bridges, ensuring that they are safe for use and functioning properly.

Efforts are also underway to assist residents and businesses affected by the flooding. Financial aid and support programs are being implemented to help those who have suffered property damage or loss, including customers affected by Toronto power outages as repairs continue. The city is working closely with insurance companies to facilitate claims and provide relief to those in need.

In addition to the immediate cleanup, there is a heightened focus on evaluating and improving the city's flood management systems. The recent storms have highlighted vulnerabilities in Toronto’s infrastructure, prompting calls for enhanced flood prevention measures. City officials and urban planners are assessing the current drainage systems and exploring ways to bolster their capacity to handle future extreme weather events.

The storms have also sparked discussions about the broader implications of climate change and its impact on urban areas. Experts suggest that increasingly severe weather events, including heavy rainfall and flooding, may become more common, as seen with Houston's extended power outage after severe storms, as global temperatures rise. This has led to a call for more resilient and adaptable infrastructure to better withstand such events.

Community organizations and volunteers have played a vital role in the recovery process. Local groups have come together to support their neighbors, providing assistance with cleanup efforts, distributing supplies, and offering emotional support to those affected by the disaster. Their contributions underscore the importance of community solidarity in times of crisis.

As Toronto works towards recovery, there is a clear recognition of the need for a comprehensive strategy to address both the immediate and long-term challenges posed by severe weather events. The city’s response will involve not only repairing the damage caused by this storm but also investing in infrastructure improvements, drawing lessons from London power outage disruption cases to harden critical systems, and adopting measures to mitigate the impact of future floods.

In summary, the severe storms that recently struck Toronto have led to widespread flooding and significant disruption across the city. The immediate response has involved extensive cleanup efforts, damage assessment, and support for affected residents and businesses. Looking ahead, Toronto faces the challenge of enhancing its flood management systems and preparing for the potential impacts of climate change. The collective efforts of emergency services, city officials, and community members will be crucial in ensuring a swift recovery and building resilience against future storms.

Egypt, China's Huawei discuss electricity network's transformation to smart grid

Egypt-Huawei Smart Grid advances Egypt's energy sector with digital transformation, grid modernization, and ICT solutions, enhancing power generation, transmission, and distribution while enabling renewable integration, data analytics, cybersecurity, and scalable infrastructure nationwide.

 

Key Points

An Egypt-Huawei project to modernize Egypt's grid into a smart network using ICT, analytics, and scalable infrastructure.

✅ Gradual migration to a smart grid to absorb higher load

✅ Boosts generation, transmission, and distribution efficiency

✅ ICT training supports workforce and digital transformation

 

Egypt and China's tech giant Huawei on Thursday discussed the gradual transformation of Egypt's electricity network to a smart grid model, Egyptian Ministry of Electricity and Renewable Energy said.

Egyptian Minister of Electricity and Renewable Energy Mohamed Shaker met with Huawei's regional president Li Jiguang in Cairo, where they discussed the cooperation, the ministry said in a statement.

The meeting is part of Egypt's plans to develop its energy sector based on the latest technologies and smarter electricity infrastructure initiatives, it added.

During the meeting, Shaker hailed the existing cooperation between Egypt and China in several mega projects, citing regional efforts like the Philippines power grid upgrades, welcoming further cooperation with China to benefit from its expertise and technological progress.

"The future vision of the Egyptian electricity sector is based on the gradual transformation of the current network from a typical one to a smart grid that would help absorb the large amounts of generated power," Shaker said.

Shaker highlighted his ministry's efforts to improve its services, including power generation, transportation and grid improvements across distribution.

Li, president of Huawei Northern Africa Enterprise Business Group, commended the rapid and remarkable development of the projects implemented by the Egyptian ministry to establish a strong infrastructure along with a smart grid that supports the digital grid transformation.

The Huawei official added that despite the challenges the corporation faced in the first half of 2020, it has managed to achieve revenues growth, which shows Huawei's strength and stability amid global challenges such as cybersecurity fears in critical infrastructure.

In late February, Egypt's Ministry of Higher Education and Scientific Research and Huawei discussed plans to provide training to develop the skills of Egyptian university students talented in information and communications technology, including emerging topics like 5G energy use considerations.
