With Duke Energy dangling money to help pay for buried power lines, the city of Greenville is studying five areas where the conversion could start.

City Manager Jim Bourey declined to identify the pilot areas specifically but said they areas include an older, heavily treed residential area; a redevelopment area; a commercial area; a "larger lot" development area; and a major residential street.

A little more than a year after a devastating ice storm - the seventh in 10 years - caused six deaths and knocked out power to half a million local people, Duke has ended years of resistance by agreeing to divert a slice of local revenues into a burial fund.

The Greenville News had reported that burying lines would cost a fraction of Duke's previous estimates if a gradual effort focused on residential areas. Studies show underground lines can dramatically reduce power outages.

Under the new agreement, Duke would match money contributed by cities by putting up to half a percent of its local revenues - or about $364,000 a year in Greenville - into a fund. Utilities such as South Carolina Electric & Gas have offered such a plan in the Midlands for a decade.

City resident Brad Bays said it's "a great result," and the product of public pressure to mitigate storm damage.

Bourey said the effort by a city task force includes looking for ways to match Duke's money, figuring out how to involve citizens and recommending an approach to the City Council.

The city puts its $2 million annual franchise fee from Duke into its general fund.

The News reported last year that Duke's internal estimates show it would cost an average of $284,000 a mile to put residential power lines underground.

There are 107 miles of residential lines in the city.

Bourey said the task force, including utility officials, experts and citizens, is now studying specific costs such as trenching versus boring, burying under sidewalks or under roads.

He said there have been some discussions of using the burial fund to help pay for the drop line that connects a home to the power system.

Bourey said property owners have to be involved because there are added costs to hook into the system and bury other utility lines on the same poles.

He said specifics should emerge within a few months.

Bays said the areas most prone to ice storm damage and power outages should be buried first - likely the most difficult projects in the most heavily treed neighborhoods.

Still, despite digging and tree work that could rankle some residents, he believes the end result could benefit everyone.

"You can restore it where it's in like condition as before," Bays said. "It just depends on (the city's) attitude."

What's at stake if Davis-Besse and other nuclear plants close early?

FirstEnergy Nuclear Plant Closures threaten Ohio and Pennsylvania jobs, tax revenue, and grid stability, as Nuclear Matters and Brattle Group warn of higher carbon emissions and market pressures from PJM and cheap natural gas.

 

Key Points

Planned shutdowns of Davis-Besse, Perry, and Beaver Valley, with regional economic and carbon impacts.

✅ Over 3,000 direct jobs and local tax revenue at risk

✅ Emissions may rise until renewables scale, possibly into 2034

✅ Debate over subsidies, market design, and PJM capacity rules

 

A national nuclear lobby wants to remind people what's at stake for Ohio and Pennsylvania if FirstEnergy Solutions follows through with plans to shut down three nuclear plants over the next three years, including its Davis-Besse nuclear plant east of Toledo.

A report issued Monday by Nuclear Matters largely echoes concerns raised by FES, a subsidiary of FirstEnergy Corp., and other supporters of nuclear power about economic and environmental hardships and brownout risks that will likely result from the planned closures.

Along with Davis-Besse, Perry nuclear plant east of Cleveland and the twin-reactor Beaver Valley nuclear complex west of Pittsburgh are slated to close.

"If these plants close, the livelihoods of thousands of Ohio and Pennsylvania residents will disappear. The over 3,000 highly skilled individuals directly employed by these sites will leave to seek employment at other facilities still operating around the country," Lonnie Stephenson, International Brotherhood of Electrical Workers president, said in a statement distributed by Nuclear Matters. Mr. Stephenson also serves on the Nuclear Matters advocacy council.

This new report and others like it are part of an extensive campaign by nuclear energy advocates to court state and federal legislators one more time for tens of millions of dollars of financial support or at least legislation that better suits the nuclear industry. Critics allege such pleas amount to a request for massive government bailouts, arguing that deregulated electricity markets should not subsidize nuclear.

The latest report was prepared for Nuclear Matters by the Brattle Group, a firm that specializes in analyzing economic, finance, and regulatory issues for corporations, law firms, and governments.

"These announced retirements create a real urgency to learn what would happen if these plants are lost," Dean Murphy, the Brattle report's lead author, said.

More than 3,000 jobs would be lost, as would millions of dollars in tax revenue. It also could take as long as 2034 for the region's climate-altering carbon emissions to be brought back down to existing levels, based on current growth projections for solar- and wind-powered projects, and initiatives such as ending coal by 2032 by some utilities, Mr. Murphy said.

His group's report only takes into account nuclear plant operations, though. Many of those who oppose nuclear power have long pointed out that mining uranium for nuclear plant fuel generates substantial emissions, as does the process of producing steel cladding for fuel bundles and the enrichment-production of that fuel. Still, nuclear has ranked among the better performers in reports that have taken such a broader look at overall emissions.

FES has accused the regional grid operator, PJM Interconnection, of creating market conditions that favor natural gas and, thus, make it almost impossible for nuclear to compete throughout its 13-state region, a debate intensified by proposed electricity pricing changes at the federal level.

PJM has strongly denied those accusations, and has said it anticipates no shortfalls in energy distribution if those nuclear plants close prematurely, even as a recent FERC decision on grid policy drew industry criticism.

FES, citing massive losses, has filed for Chapter 11 bankruptcy. The target dates for closures of the FES properties are May 31, 2020 for Davis-Besse; May 31, 2021 for Perry and Beaver Valley Unit 1, and Oct. 31, 2021 for Beaver Valley Unit 2.

In addition to the three FES sites, the report includes information about the Three Mile Island Unit 1 plant near Harrisburg, Pa., which Chicago-based Exelon Generation Corp. has previously announced will be shut down in 2019. That plant and others are experiencing similar difficulties the FES plants face by competing in a market radically changed by record-low natural gas prices.

Are Norwegian energy firms ‘best in class’ for environmental management?

CO2 Tax for UK Offshore Energy Efficiency can accelerate adoption of aero-derivative gas turbines, flare gas recovery, and combined cycle power, reducing emissions on platforms like Equinor's Mariner and supporting net zero goals.

 

Key Points

A carbon price pushing operators to adopt efficient turbines, flare recovery, and combined cycle to cut emissions.

✅ Aero-derivative turbines beat industrial units on efficiency

✅ Flare gas recovery cuts routine flaring and fuel waste

✅ Combined cycle raises efficiency and lowers emissions

 

By Tom Baxter

The recent Energy Voice article from the Equinor chairman concerning the Mariner project heralding a ‘significant point of reference’ for growth highlighted the energy efficiency achievements associated with the platform.

I view energy efficiency as a key enabler to net zero, and alongside this the UK must start large-scale storage to meet system needs; it is a topic I have been involved with for many years.

As part of my energy efficiency work, I investigated Norwegian practices and compared them with the UK.

There were many differences, here are three;


1. Power for offshore installations is usually supplied from gas turbines burning fuel from the oil and gas processing plant, and even as the UK's offshore wind supply accelerates, installations convert that to electricity or couple the gas turbine to a machine such as a gas compressor.

There are two main generic types of gas turbine – aero-derivative and industrial. As the name implies aero-derivatives are aviation engines used in a static environment. Aero-derivative turbines are designed to be energy efficient as that is very import for the aviation industry.

Not so with industrial type gas turbines; they are typically 5-10% less efficient than a comparable aero-derivative.

Industrial machines do have some advantages – they can be cheaper, require less frequent maintenance, they have a wide fuel composition tolerance and they can be procured within a shorter time frame.

My comparison showed that aero-derivative machines prevailed in Norway because of the energy efficiency advantages – not the case in the UK where there are many more offshore industrial gas turbines.

Tom Baxter is visiting professor of chemical engineering at Strathclyde University and a retired technical director at Genesis Oil and Gas Consultants


2. Offshore gas flaring is probably the most obvious source of inefficient use of energy with consequent greenhouse gas emissions.

On UK installations gas is always flared due to the design of the oil and gas processing plant.

Though not a large quantity of gas, a continuous flow of gas is routinely sent to flare from some of the process plant.

In addition the flare requires pilot flames to be maintained burning at all times and, while Europe explores electricity storage in gas pipes, a purge of hydrocarbon gas is introduced into the pipes to prevent unsafe air ingress that could lead to an explosive mixture.

On many Norwegian installations the flare system is designed differently. Flare gas recovery systems are deployed which results in no flaring during continuous operations.

Flare gas recovery systems improve energy efficiency but they are costly and add additional operational complexity.


3. Returning to gas turbines, all UK offshore gas turbines are open cycle – gas is burned to produce energy and the very hot exhaust gases are vented to the atmosphere. Around 60 -70% of the energy is lost in the exhaust gases.

Some UK fields use this hot gas as a heat source for some of the oil and gas treatment operations hence improving energy efficiency.

There is another option for gas turbines that will significantly improve energy efficiency – combined cycle, and in parallel plans for nuclear power under the green industrial revolution aim to decarbonise supply.

Here the exhaust gases from an open cycle machine are taken to a separate turbine. This additional turbine utilises exhaust heat to produce steam with the steam used to drive a second turbine to generate supplementary electricity. It is the system used in most UK power stations, even as UK low-carbon generation stalled in 2019 across the grid.

Open cycle gas turbines are around 30 – 40% efficient whereas combined cycle turbines are typically 50 – 60%. Clearly deploying a combined cycle will result in a huge greenhouse gas saving.

I have worked on the development of many UK oil and gas fields and combined cycle has rarely been considered.

The reason being is that, despite the clear energy saving, they are too costly and complex to justify deploying offshore.

However that is not the case in Norway where combined cycle is used on Oseberg, Snorre and Eldfisk.

What makes the improved Norwegian energy efficiency practices different from the UK – the answer is clear; the Norwegian CO2 tax.

A tax that makes CO2 a significant part of offshore operating costs.

The consequence being that deploying energy efficient technology is much easier to justify in Norway when compared to the UK.

Do we need a CO2 tax in the UK to meet net zero – I am convinced we do. I am in good company. BP, Shell, ExxonMobil and Total are supporting a carbon tax.

Not without justification there has been much criticism of Labour’s recent oil tax plans, alongside proposals for state-owned electricity generation that aim to reshape the power market.

To my mind Labour’s laudable aims to tackle the Climate Emergency would be much better served by supporting a CO2 tax that complements the UK's coal-free energy record by strengthening renewable investment.

Duke Energy Florida's smart-thinking grid improves response, power restoration for customers during Hurricane Ian

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.

ABO to build 10MW Tunisian solar park

ABO Wind Tunisia 10MW Solar Project will build a photovoltaic park in Gabes with a STEG PPA, fixed tariff, 2,500 m grid connection, producing 18 million kWh annually, targeted for 2020 commissioning with local partners.

 

Key Points

A 10MW photovoltaic park in Gabes with a 20-year STEG PPA and fixed tariff, slated for 2020 commissioning.

✅ 18 million kWh/year; 2,500 m grid tie, 20-year fixed tariff

✅ Electricity supplied to STEG under PPA; 2020 commissioning

✅ Located in Gabes; built with local partners, 10MW capacity

 

ABO Wind has received a permit and a tariff for a 10MW photovoltaic project in Tunisia, amid global activity such as Spain's 90MW wind project now underway, which it plans to build and commission in 2020.

The solar park, in the governorate of Gabes, is 400km south of the country’s capital Tunis and aligns with renewable funding initiatives seen across developing markets.

The developer said it plans to build the project next year in close cooperation with local partners, as regional markets from North Africa to the Gulf expand, with Saudi Arabia boosting wind capacity as well.

ABO Wind department head Nicolas Konig said: “The solar park will produce more than 18 million kilowatt hours of electricity per year and will feed it into the grid at a distance of 2500 metres.”

The developer will conclude an electricity supply contract with the state-owned energy supplier (Societe tunisienne de l’electricite et du gaz (STEG), which will provide a fixed remuneration over 20 years, a model echoed by Germany's wind-solar tender for the electricity fed into the grid.

Earlier this year, ABO Wind had already secured a tariff for a wind farm with a capacity of 30MW in a tender, 35km south-east of Tunis, underscoring Tunisia's wind investments under its long-term plan.

The company is working on half a dozen Tunisian wind and solar projects, as institutions like the World Bank support wind growth in developing countries.

“We are making good progress on our way to assemble a portfolio of several ready-to-build wind and solar projects attractive to investors, as Saudi clean energy targets continue to expand globally,” said ABO Wind general manager responsible for international business development Patrik Fischer.

By aligning these proposals with the incoming Trump administration's pro-tech stance, OpenAI seeks to secure federal support for its projects.

Engagement with the Trump Administration

The transition from the Biden administration to the incoming Trump administration presents new opportunities for OpenAI, even as state legal challenges shape early energy policy moves. The Trump administration is perceived as more favorable toward the tech industry, with appointments of Silicon Valley figures like Elon Musk and David Sacks to key positions. OpenAI is leveraging this environment to advocate for policies that support AI development and infrastructure expansion, positioning itself as a strategic asset in the U.S.-China economic and security competition.

The AI industry is increasingly viewed as a critical component of national security and economic competitiveness. OpenAI's efforts to engage with policymakers reflect a broader industry push to be recognized as a vital player in the U.S. economic and security landscape. By promoting AI as a strategic asset, OpenAI aims to secure support for its initiatives, including clean-energy projects in coal communities, and ensure that the U.S. remains at the forefront of AI innovation.

OpenAI's strategic expansion in Washington, D.C., underscores its commitment to influencing policy decisions that will shape the future of AI and its integration into critical sectors. By enhancing its policy team, advocating for infrastructure development, where Alberta's data center boom illustrates rising demand, and aligning with the incoming administration's priorities, even as energy dominance goals face real-world constraints, OpenAI aims to position itself as a key player in the evolving landscape of artificial intelligence. This proactive approach reflects the company's recognition of the importance of policy engagement in driving innovation and securing a competitive edge in the global AI arena.

Sudbury, Ont., eco groups say sustainability is key to grid's future

Sudbury Electrification and Grid Expansion is driving record power demand, EV charging, renewable energy planning, IESO forecasts, smart grid upgrades, battery storage, and industrial electrification, requiring cleaner power plants and transmission capacity in northern Ontario.

 

Key Points

Rising electricity demand and clean energy upgrades in Sudbury to power EVs, industry, and a smarter, expanded grid.

✅ IESO projects system size may need to more than double

✅ EVs and smart devices increase peak and off-peak load

✅ Battery storage and V2G can support reliability and resiliency

 

Sudbury, Ont., is consuming more power than ever, amid an electricity supply crunch in Ontario, according to green energy organizations that say meeting the demand will require cleaner energy sources.

"This is the welfare of the entire city on the line and they are putting their trust in electrification," said David St. Georges, manager of communications at reThink Green, a non-profit organization focused on sustainability in Sudbury.

According to St. Georges, Sudbury and northern Ontario can meet the growing demand for electricity to charge clean power for EVs and smart devices. 

According to the Independent Electricity System Operator (IESO), making a full switch from fossil fuels to other renewable energy sources could require more power plants, while other provinces face electricity shortages of their own.

"We have forecasted that Ontario's electricity system will need significant expansion to meet this, potentially more than doubling in size," the IESO told CBC News in an emailed statement.

Electrification in the industrial sector is adding greater demand to the electrical grid as electric cars challenge power grids in many regions. Algoma Steel in Sault Ste. Marie and ArcelorMittal Dofasco in Hamilton both aim to get electric arc furnaces in operation. Together, those projects will require 630 megawatts.

"That's like adding four cities the size of Sudbury to the grid," IESO said.

Devin Arthur, chapter president of the Electric Vehicle society in Greater Sudbury, said the city is coming full circle with fully electrifying its power grid, reflecting how EVs are a hot topic in Alberta and beyond.

"We're going to need more power," he said.

"Once natural gas was introduced, that kind of switched back, and everyone was getting out of electrification and going into natural gas and other sources of power."

Despite Sudbury's increased appetite for electricity, Arthur added it's also easier to store now as Ontario moves to rely on battery storage solutions.

"What that means is you can actually use your electric vehicle as a battery storage device for the grid, so you can actually sell power from your vehicle that you've stored back to the grid, if they need that power," he said.

Harneet Panesar, chief operating officer for the Ontario Energy Board, told CBC the biggest challenge to going green is seeing if it can work around older infrastructure, while policy debates such as Canada's 2035 EV sales mandate shape the pace of change.

"You want to make sure that you're building in the right spot," he said.

"Consumers are shifting from combustion engines to EV drivetrains. You're also creating more dependency. At a very high level, I'm going to say it's probably going to go up in terms of the demand for electricity."

Fossil fuels are the first to go for generating electricity, said St. Georges.

"But we're not there yet, because it's not a light switch solution. It takes time to get to that, which is another issue of electrification," he said.

"It's almost impossible for us not to go that direction."
