Duke Energy Clean Energy Strategy targets smart grid upgrades, wind and solar expansion, efficient gas, and high-reliability nuclear, cutting CO2, boosting decarbonization, and advancing energy efficiency and reliability for the Carolinas.

Key Points

A plan investing in smart grids, renewables, gas, and nuclear to cut CO2 and enhance reliability and efficiency by 2030.

✅ US$25bn smart grid upgrades; US$11bn renewables and gas

✅ 40% CO2 reduction and >80% low-/zero-carbon generation by 2030

✅ 2017 nuclear fleet 95.64% capacity factor; ~90 TWh carbon-free

The US power group Duke Energy plans to invest US$25bn on grid modernization over the 2017-2026 period, including the implementation of smart grid technologies to cope with the development of renewable energies, along with US$11bn on the expansion of renewable (wind and solar) and gas-fired power generation capacities.

The company will modernize its fleet and expects more than 80% of its power generation mix to come from zero and lower CO2 emitting sources, aligning with nuclear and net-zero goals, by 2030. Its current strategy focuses on cutting down CO2 emissions by 40% by 2030. Duke Energy will also promote energy efficiency and expects cumulative energy savings - based on the expansion of existing programmes - to grow to 22 TWh by 2030, i.e. the equivalent to the annual usage of 1.8 million households.

Duke Energy’s 11 nuclear generating units posted strong operating performance in 2017, as U.S. nuclear costs hit a ten-year low, providing the Carolinas with nearly 90 billion kilowatt-hours of carbon-free electricity – enough to power more than 7 million homes.

Globally, China's nuclear program remains on a steady development track, underscoring broader industry momentum.

“Much of our 2017 success is due to our focus on safety and work efficiencies identified by our nuclear employees, along with ongoing emphasis on planning and executing refueling outages to increase our fleet’s availability for producing electricity,” said Preston Gillespie, Duke Energy chief nuclear officer.

Some of the nuclear fleet’s 2017 accomplishments include, as a new U.S. reactor comes online nationally:

• The 11 units achieved a combined capacity factor of 95.64 percent, second only to the fleet’s 2016 record of 95.72 percent, marking the 19th consecutive year of attaining a 90-plus percent capacity factor (a measure of reliability).
• The two units at Catawba Nuclear Station produced more than 19 billion kilowatt-hours of electricity, and the single unit at Harris Nuclear Plant generated more than 8 billion kilowatt-hours, both setting 12-month records.
• Brunswick Nuclear Plant unit 2 achieved a record operating run.
• Both McGuire Nuclear Station units completed their shortest refueling outages ever and unit 1 recorded its longest operating run.
• Oconee Nuclear Station unit 2 achieved a fleet record operating run.

The Robinson Nuclear Plant team completed the station’s 30th refueling outage, which included a main generator stator replacement and other life-extension activities, well ahead of schedule.

“Our nuclear employees are committed to providing reliable, clean electricity every day for our Carolinas customers,” added Gillespie. “We are very proud of our team’s 2017 accomplishments and continue to look for additional opportunities to further enhance operations.”

Manitoba Hydro capacity constraints challenge clean energy growth as industrial demand, hydrogen projects, EV batteries, and electrification strain the grid; limited surplus, renewables, storage, and transmission bottlenecks hinder new high-load connections.

Key Points

Limited surplus power blocks new energy-intensive loads until added generation and transmission expand Manitoba's grid.

✅ No firm commitments for new energy-intensive industrial customers

✅ Single large load could consume remaining surplus capacity

✅ New renewables need transmission; gas, nuclear face trade-offs

Manitoba Hydro lacks the capacity to provide electricity to any new "energy intensive" industrial customers, the Crown corporation warns in a confidential briefing note that undercuts the idea this province can lure large businesses with an ample supply of clean, green energy, as the need for new power generation looms for the utility.

On July 28, provincial economic development officials unveiled an "energy roadmap" that said Manitoba Hydro must double or triple its generating capacity, as electrical demand could double over the next two decades in order to meet industrial and consumer demand for electricity produced without burning fossil fuels.

Those officials said 18 potential new customers with high energy needs were looking at setting up operations in Manitoba — and warned the province must be careful to choose businesses that provide the greatest economic benefit as well as the lowest environmental impact.

In a briefing note dated Sept. 13, obtained by CBC News, Manitoba Hydro warns it doesn't have enough excess power to hook up any of these new heavy electricity-using customers to the provincial power grid.

There are actually 57 proposals to use large volumes of electricity, Hydro says in the note, including eight projects already in the detailed study phase and nine where the proponents are working on construction agreements.

"Manitoba Hydro is unable to offer firm commitments to prospective customers that may align with Manitoba's energy roadmap and/or provincial economic development objectives," Hydro warns in the note, explaining it is legally obliged to serve all existing customers who need more electricity.

"As such, Manitoba Hydro cannot reserve electric supply for particular projects."

Hydro says in the note its "near-term surplus electricity supply" is so limited amid a Western Canada drought that "a single energy-intensive connection may consume all remaining electrical capacity."

Adding more electrical generating capacity won't be easy, even with new turbine investments underway, and will not happen in time to meet demands from customers looking to set up shop in the province, Hydro warns.

The Crown corporation goes on to say it's grappling with numerous requests from existing and prospective energy-intensive customers, mainly for producing hydrogen, manufacturing electric vehicle batteries and switching from fossil fuels to electricity, such as to use electricity for heat in buildings.

In a statement, Hydro said it wants to ensure Manitobans know the corporation is not running out of power — just the ability to meet the needs of large new customers, and continues to provide clean energy to neighboring provinces today.

"The size of loads looking to come to Manitoba are significantly larger than we typically see, and until additional supply is available, that limits our ability to connect them," Hydro spokesperson Bruce Owen said in a statement.

Adding wind power or battery storage, for example, would require the construction of more transmission lines, and deals such as SaskPower's purchase depend on that interprovincial infrastructure as well.

Natural gas plants are relatively inexpensive to build but do not align with efforts to reduce carbon emissions. Nuclear power plants require at least a decade of lead time to build, and tend to generate local opposition.

Hydro has also ruled out building another hydroelectric dam on the Nelson River, where the Conawapa project was put on hold in 2014.

EU Renewable Energy Transition is accelerating under REPowerEU, as wind and solar generation hit records, improving energy security, efficiency, and decarbonization while reducing reliance on Russian fossil fuels across the EU grid.

Key Points

EU shift to wind and solar under REPowerEU to cut fossil fuels, boost efficiency, and secure energy supply.

✅ Wind and solar set record 22% of EU electricity in 2022

✅ REPowerEU targets over 40% renewables and 15% lower demand by 2030

✅ Diversifies away from Russian fuels; partners with US and Norway

Europe is producing all-time highs of wind and solar energy as the 27-country group works to reduce its reliance on fossil fuels from Russia, a shift underscored by Europe's green surge across the bloc.

Four months after Vladimir Putin’s full-scale invasion of Ukraine in February 2022, the European Commission launched REPowerEU. This campaign aims to:

• Boost the use of renewable energy.
• Reduce overall energy consumption.
• Diversify energy sources.

EU countries were already moving toward renewable energy, but Russia’s war against Ukraine accelerated that trend. In 2022, for the first time, renewables surpassed fossil fuels and wind and solar power surpassed gas as a source of electricity. Wind and solar provided a record-breaking 22% of EU countries’ electrical supply, according to London-based energy think tank Ember.

“We have to double down on investments in home-grown renewables,” European Commission President Ursula von der Leyen said in October 2022. “Not only for the climate but also because the transition to the clean energy is the best way to gain independence and to have security of energy supply.”

Across the continent, growth in solar generation rose by 25% in 2022, according to Ember, as solar reshapes electricity prices in Northern Europe. Twenty EU countries produced their highest share of solar power in 2022. In October, Greece ran entirely on renewables for several hours and is seven years ahead of schedule for its 2030 solar capacity target.

Meanwhile, Ireland's green electricity target aims to make more than a third of its power supply renewable within four years.

By 2030, RePowerEU aims to provide more than 40% of the EU’s total power from renewables, aligning with global renewable records being shattered worldwide.

To meet the European Commission’s goal to cut EU energy usage by 15%, people and governments changed their habits and became more energy-efficient, while Germany's solar power boost helped bolster supply. Among their actions:

• Germany turned down the heat in public buildings and lowered the cost of train tickets to reduce car usage, as clean energy hit 50% in Germany during this period.
• Spain ordered stores and public buildings to turn off their lights at night.
• France dimmed the Eiffel Tower and reduced city speed limits.

For the oil and gas that the EU still needed to import, countries turned to partners such as Norway and the United States.

Work From Home Energy Consumption is driving higher electricity bills as residential usage rises. Smart meter data, ISO-New-England trends, and COVID-19 telecommuting show stronger power demand and sensitivity to utility rates across regions.

Key Points

Higher household electricity use from telecommuting, shifting load to residences and raising utility bills.

✅ Smart meters show 5-22 percent residential usage increases.

✅ Commercial demand fell as home cooling and IT loads rose.

✅ Utility rates and AC use drive bill spikes during summer.

Don't be surprised if your electric bills are looking higher than usual, with a sizable increase in the amount of power that you have used.

Summer traditionally is a peak period for electricity usage because of folks' need to run fans and air-conditioners to cool their homes or run that pool pump. But the arrival of the coronavirus and people working from home is adding to amount of power people are using.

Under normal conditions, those who work in their employer's offices might not be cooling their homes as much during the middle of the day or using as much electricity for lights and running computers.

For many, that's changed.

Estimates on how much of an increase residential electric customers are seeing as result of working from home vary widely.

ISO-New England, the regional electric grid operator, has seen a 3 percent to 5 percent decrease in commercial and industrial power demand, even as the grid overseer issued pandemic warnings nationally. The expectation is that much of that decrease translates into a corresponding increase in residential electricity usage.

But other estimates put the increase in residential electricity usage much higher. A Washington state company that makes smart electric meters, Itron, estimates that American households are using 5 percent to 10 percent more electricity per month since March, when many people began working from home as part of an effort to prevent the spread of the coronavirus.

Another smart metering company, Cambridge, Mass.-based Sense, found that average home electricity usage increased 22 percent in April compared to the same period in 2019, a reflection of people using more electricity while they stayed home. Based on its analysis of data from 5,000 homes across 30 states, Sense officials said a typical customer's monthly electric bill increased by between $22 and $25, with a larger increase for consumers in states with higher electricity rates.

Connecticut-specfic data is harder to come by.

Officials with Orange-based United Illuminating declined to provide any customer usage data, though, like others in the power industry, they did acknowledge that residential customers are using more electricity. And the state's other large electric distribution utility, Eversource, was unable to provide any recent data on residential electric usage. The company did tell Connecticut utility regulators there was a 3 percent increase in residential power usage for the week of March 21 compared to the week before.

Over the same time period, Eversource officials saw a 3 percent decrease in power usage by commercial and industrial customers.

Separately, nuclear plant workers raised concerns about pandemic precautions at some facilities, reflecting operational strains.

Alan Behm of Cheshire said he normally uses 597 kilowatt hours of electricity during an average month. But in April of this year, the amount of electricity he used rose by nearly 51 percent.

With many offices closed, the expense of heating, cooking and lighting is being shifted from employer to employee, and some utilities such as Manitoba Hydro have pursued unpaid days off to trim costs during the pandemic. And one remote work expert believes some companies are recognizing the burden those added costs are placing on workers -- and are trying to do something about it.

Technology giant Google announced in late May that it was giving employees who work from home $1,000 allowances to cover equipment costs and other expenses associated with establishing a home office.

Moe Vela, chief transparency officer for the New York City-based computer software company TransparentBusiness, said the move by Google executives is a savvy one.

"Google is very smart to have figured this out," Vela said. "This is what employees want, especially millenials. People are so much happier to be working remotely, getting those two to three hours back per day that some people spend getting to and from work is so much more important than a stipend."

Vela predicted that even after a vaccine is found for the corona virus, one of the key worklife changes is likely to be a broader acceptance of telework and working from home.

Beyond the immediate shifts, more young Canadians would work in electricity if awareness improved, pointing to future talent pipelines.

"I think that's where we're headed," he said. "I think it will make an employer more attractive as they try to attract talent from around the world."

Vela said employers save an average of $11,000 per year for each employee they have working from home.

"It would be a brilliant move if a company were to share some of that amount with employees," he said. "I wouldn't do it if it's going to cause a company to not be there (in business) though."

The idea of a company sharing whatever savings it achieves by having employees work from home wasn't well received by many Connecticut residents who responded to questions posed via social media by Hearst Connecticut Media. More than 100 people responded and an overwhelming number of people spoke out against the idea.

"You are saving on gas and other travel related expenses, so the small increase in your electric bill shouldn't really be a concern," said Kathleen Bennett Charest of Wallingford.

Jim Krupp, also of Wallingford, said, "to suggest that the employers compensate the employees makes as much sense as suggesting that the employees should take a pay cut due to their reduced expenses for travel, day care, and eating lunch at work."

"Employers must still maintain their offices and incur all of the fixed expenses involved, including basic utilities, taxes and insurance," Krupp said. "The cost savings (for employers) that are realized are also offset by increased costs of creating and maintaining IT networks that allow employees to access their work sites from home and the costs of monitoring and managing the work force."

Kiki Nichols Nugent of Cheshire said she was against the idea of an employee trying to get their employer to pay for the increased electricity costs associated with working from home.

"I would not nickle and dime," Nugent said. "If companies are saving on electricity now, maybe employers will give better raises next year."

New Haven resident Chris Smith said he is "just happy to have a job where I am able to telecommute."

"When teleworking becomes more the norm, either now or in the future, we may see increased wages for teleworkers either for the lower cost to the employer or for the increase in productivity it brings," Smith said.

Attosecond Electron Transport uses ultrafast lasers and single-cycle light pulses to drive tunneling in bowtie gold nanoantennas, enabling sub-femtosecond switching in optoelectronic nanostructures and surpassing picosecond silicon limits for next-gen computing.

Key Points

A light-driven method that manipulates electrons with ultrafast pulses to switch currents within attoseconds.

✅ Uses single-cycle light pulses to drive electron tunneling

✅ Achieves 600 attosecond current switching in nano-gaps

✅ Enables optoelectronic, plasmonic devices beyond silicon

When it comes to data transfer and computing, the faster we can shift electrons and conduct electricity the better – and scientists have just been able to transport electrons at sub-femtosecond speeds (less than one quadrillionth of a second) in an experimental setup.

The trick is manipulating the electrons with light waves that are specially crafted and produced by an ultrafast laser. It might be a long while before this sort of setup makes it into your laptop, but similar precision is seen in noninvasive interventions where targeted electrical stimulation can boost short-term memory for limited periods, and the fact they pulled it off promises a significant step forward in terms of what we can expect from our devices.

Right now, the fastest electronic components can be switched on or off in picoseconds (trillionths of a second), a pace that intersects with debates over 5G electricity use as systems scale, around 1,000 times slower than a femtosecond.

With their new method, the physicists were able to switch electric currents at around 600 attoseconds (one femtosecond is 1,000 attoseconds).

"This may well be the distant future of electronics," says physicist Alfred Leitenstorfer from the University of Konstanz in Germany. "Our experiments with single-cycle light pulses have taken us well into the attosecond range of electron transport."

Leitenstorfer and his colleagues were able to build a precise setup at the Centre for Applied Photonics in Konstanz. Their machinery included both the ability to carefully manipulate ultrashort light pulses, and to construct the necessary nanostructures, including graphene architectures, where appropriate.

The laser used by the team was able to push out one hundred million single-cycle light pulses every single second in order to generate a measurable current. Using nanoscale gold antennae in a bowtie shape (see the image above), the electric field of the pulse was concentrated down into a gap measuring just six nanometres wide (six thousand-millionths of a metre).

As a result of their specialist setup and the electron tunnelling and accelerating it produced, the researchers could switch electric currents at well under a femtosecond – less than half an oscillation period of the electric field of the light pulses.

Getting beyond the restrictions of conventional silicon semiconductor technology has proved a challenge for scientists, but using the insanely fast oscillations of light to help electrons pick up speed could provide new avenues for pushing the limits on electronics, as our power infrastructure is increasingly digitized and integrated with photonics.

And that's something that could be very advantageous in the next generation of computers: scientists are currently experimenting with the way that light and electronics could work together in all sorts of different ways, from noninvasive brain stimulation to novel sensors.

Eventually, Leitenstorfer and his team think that the limitations of today's computing systems could be overcome using plasmonic nanoparticles and optoelectronic devices, using the characteristics of light pulses to manipulate electrons at super-small scales, with related work even exploring electricity from snowfall under specific conditions.

"This is very basic research we are talking about here and may take decades to implement," says Leitenstorfer.

The next step is to experiment with a variety of different setups using the same principle. This approach might even offer insights into quantum computing, the researchers say, although there's a lot more work to get through yet - we can't wait to see what they'll achieve next.

IEC-PETL Electricity Agreement streamlines grid management, debt settlement, and bank guarantees, shifting power supply, transmission, and distribution to PETL via IEC-built sub-stations, bolstering energy cooperation, utility billing, and payment assurance in PA areas.

Key Points

A 15-year deal transferring PA grid operations to PETL, settling legacy debt, and securing payments with bank guarantees.

✅ NIS 915 million repaid in 48 installments.

✅ PETL assumes distribution, O&M, and sub-station ownership.

✅ 15-year, NIS 2.8b per year supply and services contract.

The Palestinian Authority will pay Israel Electric NIS 915 million and take over management of its grid through Palestinian electricity supplier PETL.

The Israel Electric Corporation (IEC) (TASE: ELEC.B22) and Palestinian electricity supplier PETL have signed a draft commercial agreement under which the Palestinian Authority's (PA) debt of almost NIS 1 billion will be repaid. The agreement also transfers actual management of the supply of electricity to Palestinian customers from IEC to the Palestinian electricity authority, enabling consideration of distributed solutions such as a virtual power plant program in future planning.

Up until now, the IEC was unable to actually collect debts for electricity from Palestinian customers, because the connection with them was through the PA. Responsibility for collection will now be exclusively in Palestinian hands, with the PA providing hundreds of millions of shekels in bank guarantees for future debts. The agreement, which is valid for 15 years, amounts to an estimated NIS 2.8 billion a year, as of now.

IEC will sell electricity and related services to PETL through four high-tension sub-stations built by IEC for PETL and through high and low-tension connection points, similar to large interconnector projects like the Lake Erie Connector, for the purpose of distribution and supply of the electricity by PETL or an entity on its behalf to consumers in PA territory. PETL will have sole operational and maintenance responsibility for distribution and supply and ownership of the four sub-stations.

NIS 915 million in 48 payments

According to the IEC announcement, the settlement was reached following negotiations following the signing of an agreement in principle in September 2016 by the minister of finance, the government coordinator of activities in the territories, and the Palestinian minister for civilian affairs. The parties reached commercial understandings yesterday that made possible today's signing of the first commercial document of its kind regulating commercial relations - the sales of electricity - between the parties. The agreement will go into effect after it is approved by the IEC board of directors, the Public Utilities Authority (electricity), reflecting regulatory oversight akin to Ontario industrial electricity pricing consultations, and the IDF Chief Electrical Staff Officer. Representatives of IEC, the Ministry of Finance, the Public Utilities Authority (electricity), the government coordinator of activities in the territories, the civilian authority, the PA government, and PETL took part in the negotiations.

The agreement also settles the PA's historical debt to IEC. The PA will begin payment of NIS 915 million in debt for consumption of electricity before September 2016 to IEC Jerusalem District Ltd. in 48 equal installments after the final signing, as stipulated in the agreement in principle signed by the Israeli government and the PA on September 13, 2016.

The PA's debt for electricity amounted to almost NIS 2 billion in 2016. The initial spadework for the current debt settlement was accomplished in that year, after the parties reached understandings on writing off NIS 500 million of the Palestinian debt. The PA paid NIS 600 million in October 2016, and the remainder will be paid now.

It was also reported that an arrangement of securities and guarantees to ensure payment to IEC under the agreement had been settled, including the past debt. IEC will obtain a bank guarantee and a PA guarantee, in addition to the existing collection mechanisms at the company's disposal.

Minister of Finance Moshe Kahlon said, "Signing the commercial agreement is a historic step completing the agreement signed by the governments in September 2016. Strengthening economic cooperation between Israel and the PA is above all an Israeli security interest. The agreement will ensure future payments to the IEC and reinforce its financial position. I congratulate the negotiating teams for the completion of their task."

Minister of National Infrastructure, Energy, and Water Resources Dr. Yuval Steinitz said, "In my meeting last year with Palestinian Prime Minister Rami Hamdallah in Jenin, we agreed that it was necessary to settle the debt and formalize relations between IEC and the PA. The settlement signed today is a breakthrough, both in the measures for payment of the Palestinian debt to IEC and Israel and in arranging future relations to prevent more debts from emerging in the future. With the signing of the agreement, we will be able to make progress with the Palestinians in developing a modern electrical grid, aligning with regional initiatives like the Cyprus electricity highway, according to the model of the sub-station we inaugurated in Jenin."

IEC chairperson Yiftah Ron Tal said, "This is a historic event. In this agreement, IEC is correcting for the first time a historical distortion of accumulated debt without guarantees, ability to collect it, or control over the amount of debt. This anchor agreement not only constitutes an unprecedented financial achievement; it also constitutes an important milestone in regulating electricity commercial relations between the Israeli and Palestinian electric companies, comparable to cross-border efforts such as the Ireland-France interconnector in Europe."
