The Knoxville Utilities Board typically spends about $2 million annually on storm-related repairs to its system, and was on pace to close out the end of its fiscal year at the same average before last month's intense storms, officials say.

Now, "This storm will cost KUB about $1.2 million alone... but we're still counting," said Bill Elmore, KUB's senior vice president and chief operating officer, after the storms that struck Knoxville and much of the Southeast over the week of April 25.

All told, the local utility suffered 115 broken utility poles, about 100 damaged power transformers and some six miles of electrical lines that had to be restrung. The damage also left more than 44,000 KUB customers in the dark at the peak of the outages.

"I'd never seen anything like this," said KUB Engineering Manager Gabriel Bolas, who joined the utility the year after Knoxville's great blizzard of March 1993.

So if a stiff wind and a few old trees can cause that much trouble, asked Knox Know-it-all, then why not bury all of the grid's power lines underground?

Actually, that's become the preference for most local developers when they install the utility infrastructure for new subdivisions and other projects.

"Virtually everything that's going in today is going underground, and has been for the last 15 years," Elmore said. "It's a good choice. And aesthetically, it's more pleasing."

As a result, KUB's 5,200 miles of electrical lines now include about 900 miles below ground.

Burying the above-ground lines, however, is entirely too costly, Elmore said.

KUB officials cited a 2007 study funded by Florida utility companies that found underground conversions would cost, on average, about $1 million per mile.

KUB still offers such conversions as an option for homeowners' groups that ask. Among the four or five requests KUB receives each year, though, the interest usually ends when the first cost estimates are made.

"I haven't averaged one project a year yet," said Bolas. "Only about 1 out of 20 of those actually go forward."

And even when a neighborhood incurs the cost and makes the switch, it still can be susceptible to outages from above-ground breaks elsewhere, he added.

So instead of more digging, KUB maintains a tree-trimming program. The practice has sparked years of customer complaints over heavy-handed pruning and, in turn, the formation of a citizens review panel and dozens of policy changes made last year. As a means of cost effectiveness, though, KUB spends about $5 million a year on tree trimming.

Nord Stream: Norway and Denmark tighten energy infrastructure security after gas pipeline 'attack'

Nord Stream Pipeline Sabotage triggers Baltic Sea gas leaks as Norway and Denmark tighten energy infrastructure security, offshore surveillance, and exclusion zones, after drone sightings near platforms and explosions reported by experts.

 

Key Points

An alleged attack causing Baltic gas leaks and heightened energy security measures in Norway and Denmark.

✅ Norway boosts offshore and onshore site security

✅ Denmark enforces 5 nm exclusion zone near leaks

✅ Drones spotted; police probe sabotage and safety breaches

 

Norway and Denmark will increase security and surveillance around their energy infrastructure sites after the alleged sabotage of Russia's Nord Stream gas pipeline in the Baltic Sea, as the EU pursues a plan to dump Russian energy to safeguard supplies. 

Major leaks struck two underwater natural gas pipelines running from Russia to Germany, which has moved to a 200 billion-euro energy shield amid surging prices, with experts reporting that explosions rattled the Baltic Sea beforehand.

Norway -- an oil-rich nation and Europe's biggest supplier of gas -- will strengthen security at its land and offshore installations, even as it weighs curbing electricity exports to avoid shortages, the country's energy minister said.

The Scandinavian country's Petroleum Safety Authority also urged vigilance on Monday after unidentified drones were seen flying near Norway's offshore oil and gas platforms.

"The PSA has received a number of warnings/notifications from operator companies on the Norwegian Continental Shelf concerning the observation of unidentified drones/aircraft close to offshore facilities" the agency said in a statement.

"Cases where drones have infringed the safety zone around facilities are now being investigated by the Norwegian police."

Meanwhile Denmark will increase security across its energy sector after the Nord Stream incident, as wider market strains, including Germany's struggling local utilities, ripple across Europe, a spokesperson for gas transmission operator Energinet told Upstream.

The Danish Maritime Agency has also imposed an exclusion zone for five nautical miles around the leaks, warning ships of a danger they could lose buoyancy, and stating there is a risk of the escaping gas igniting "above the water and in the air," even as Europe weighs emergency electricity measures to limit prices.

Denmark's defence minister said there was no cause for security concerns in the Baltic Sea region.

"Russia has a significant military presence in the Baltic Sea region and we expect them to continue their sabre-rattling," Morten Bodskov said in a statement.

Video taken by a Danish military plane on Tuesday afternoon showed the extent of one of gas pipeline leaks, with the surface of the Baltic bubbling up as gas escapes, highlighting Europe's energy crisis for global audiences:

Meanwhile police in Sweden have opened a criminal investigation into "gross sabotage" of the Nord Stream 1 and Nord Stream 2 pipelines, and Sweden's crisis management unit was activated to monitor the situation. The unit brings together representatives from different government agencies. 

Swedish Foreign Minister Ann Linde had a call with her Danish counterpart Jeppe Kofod on Tuesday evening, and the pair also spoke with Norwegian Foreign Minister Anniken Huitfeldt on Wednesday, as the bloc debates gas price cap strategies to address the crisis, with Kofod saying there should be a "clear and unambiguous EU statement about the explosions in the Baltic Sea." 

"Focus now on uncovering exactly what has happened - and why. Any sabotage against European energy infrastructure will be met with a robust and coordinated response," said Kofod.

Metering Pilot projects may be good example for Ontario utilities

Ontario Electricity Pricing Pilot Projects explore alternative rates beyond time-of-use, with LDCs and the Ontario Energy Board testing dynamic pricing, demand management, smart-meter billing, and residential customer choice to enhance service and energy efficiency.

 

Key Points

Ontario LDC trials testing alternatives to time-of-use rates to improve billing, demand response, and efficiency.

✅ Data shared across LDCs and Ontario Energy Board provincewide

✅ Tests dynamic pricing, peak/off-peak plans, demand management

✅ Insights to enhance customer choice, bills, and energy savings

 

The results from three electricity pilot projects being offered in southern Ontario will be valuable to utility companies across the province.

Ontario Energy Minister Glenn Thibeault was in Barrie on Tuesday to announce the pilot projects, which will explore alternative pricing plans for electricity customers from three different utility companies, informed by the electricity cost allocation framework guiding rate design.

"Everyone in the industry is watching to see how the pilots deliver.", said Wendy Watson, director of communications for Greater Sudbury Utilities.

"The data will be shared will all the LDCs [local distribution companies] in the province, and probably beyond...because the industry tends to share that kind of information."

Most electricity customers in the province are billed using time-of-use rates, including options like the ultra-low overnight rates that lower costs during off-peak periods, where the cost of electricity varies depending on demand.

The Ontario Energy Board said in a media release that the projects will give residential customers more choice in how much they pay for electricity at different times, reflecting changes for Ontario electricity consumers that expand plan options.

Pilot projects can help improve service

Watson says these kinds of projects give LDCs the chance to experiment and explore new ways of delivering their service, including demand-response initiatives like the Peak Perks program that encourage conservation.

"Any pilot project is a great way to see if in practice if the theory proves out, so I think it's great that the province is supporting these LDCs," she says.

GSU recently completed its own pilot project, the Home Energy Assessment and Retrofit (HEAR) program, which focused on customers who use electric baseboards to heat their homes, amid broader provincial support for electric bills to ease costs."We installed some measures, like programmable thermostats and a few other pieces of equipment into their house," Watson says. "We also made some recommendations about other things that they could do to make their homes more energy efficient."

At the end of the program, GSU provided customers with a report so that they could the see the overall impact on their energy consumption.

Watson says a report on the results of the HEAR program will be released in the near future, for other LDCs interested in new ways to improve their service.

"We think it's incumbent on every LDC...to see what ideas that they can come up with and get approved so they can best serve their customers."

Updated Germany hydrogen strategy sees heavy reliance on imported fuel

Germany Hydrogen Import Strategy outlines reliance on green hydrogen imports, expanded electrolysis capacity, IPCEI-funded pipelines, and industrial decarbonization for steel and chemicals to reach climate-neutral goals by 2045, meeting 2030 demand of 95-130 TWh.

 

Key Points

A plan to import 50-70% of hydrogen by 2030, backing green hydrogen, electrolysis, pipelines, and decarbonization.

✅ Imports cover 50-70% of 2030 hydrogen demand

✅ 10 GW electrolysis target with state aid and IPCEI

✅ 1,800 km H2 pipelines to link hubs by 2030

 

Germany will have to import up to 70% of its hydrogen demand in the future as Europe's largest economy aims to become climate-neutral by 2045, an updated government strategy published on Wednesday showed.

The German cabinet approved a new hydrogen strategy, setting guidelines for hydrogen production, transport infrastructure and market plans.

Germany is seeking to expand reliance on hydrogen as a future energy source to bolster energy resilience and cut greenhouse emissions for highly polluting industrial sectors that cannot be electrified such as steel and chemicals and cut dependency on imported fossil fuel.

Produced using solar and wind power, green hydrogen is a pillar of Berlin's plan to build a sustainable electric planet and transition away from fossil fuels.

But even with doubling the country's domestic electrolysis capacity target for 2030 to at least 10 gigawatts (GW), Germany will need to import around 50% to 70% of its hydrogen demand, forecast at 95 to 130 TWh in 2030, the strategy showed.

"A domestic supply that fully covers demand does not make economic sense or serve the transformation processes resulting from the energy transition and the broader global energy transition overall," the document said.

The strategy underscores the importance of diversifying future hydrogen sources, including potential partners such as Canada's clean hydrogen sector, but the government is working on a separate strategy for hydrogen imports whose exact date is not clear, a spokesperson for the economy ministry said.

"Instead of relying on domestic potential for the production of green hydrogen, the federal government's strategy is primarily aimed at imports by ship," Simone Peter, the head of Germany's renewable energy association, said.

Under the strategy, state aid is expected to be approved for around 2.5 GW of electrolysis projects in Germany this year and the government will earmark 700 million euros ($775 million) for hydrogen research to optimise production methods, research minister Bettina Stark-Watzinger said.

But Germany's limited renewable energy space will make it heavily dependent on imported hydrogen from emerging export hubs such as Abu Dhabi hydrogen exports gaining scale, experts say.

"Germany is a densely populated country. We simply need space for wind and photovoltaic to be able to produce the hydrogen," Philipp Heilmaier, an energy transition researcher at Germany energy agency, told Reuters.

The strategy allows the usage of hydrogen produced through fossil energy sources preferably if the carbon is split off, but said direct government subsidies would be limited to green hydrogen.

Funds for launching a hydrogen network with more than 1,800 km of pipelines in Germany are expected to flow by 2027/2028 through the bloc's Important Projects of Common European Interest (IPCEI) financing scheme, as the EU plans to double electricity use by 2050 could raise future demand, with the goal of connecting all major generation, import and storage centres to customers by 2030.

Transport Minister Volker Wissing said his ministry was working on plans for a network of hydrogen filling stations and for renewable fuel subsidies.

Environmental groups said the strategy lacked binding sustainability criteria and restriction on using hydrogen for sectors that cannot be electrified instead of using it for private heating or in cars, calling for a plan to eventually phase-out blue hydrogen which is produced from natural gas.

Germany has already signed several hydrogen cooperation agreements with countries such as clean energy partnership with Canada and Norway, United Arab Emirates and Australia.

Alberta Faces Challenges with Solar Energy Expansion

Alberta Solar Energy Expansion confronts high installation costs, grid integration and storage needs, and environmental impact, while incentives, infrastructure upgrades, and renewable targets aim to balance reliability, land use, and emissions reductions provincewide.

 

Key Points

Alberta Solar Energy Expansion is growth in solar tempered by costs, grid limits, environmental impact, and incentives.

✅ High capex and financing challenge utility-scale projects

✅ Grid integration needs storage, transmission, and flexibility

✅ Site selection must mitigate land and wildlife impacts

 

Alberta's push towards expanding solar power is encountering significant financial and environmental hurdles. The province's ambitious plans to boost solar power generation have been met with both enthusiasm and skepticism as stakeholders grapple with the complexities of integrating large-scale solar projects into the existing energy framework.

The Alberta government has been actively promoting solar energy as part of its strategy to diversify the energy mix in a province that is a powerhouse for both green energy and fossil fuels today and reduce greenhouse gas emissions. Recent developments have highlighted the potential of solar power to contribute to Alberta's clean energy goals. However, the path forward is fraught with challenges related to costs, environmental impact, and infrastructure needs.

One of the primary issues facing the solar energy sector in Alberta is the high cost of solar installations. Despite decreasing costs for solar technology in recent years, the upfront investment required for large-scale solar farms remains substantial, even as some facilities have been contracted at lower cost than natural gas in Alberta today. This financial barrier has led to concerns about the economic viability of solar projects and their ability to compete with other forms of energy, such as natural gas and oil, which have traditionally dominated Alberta's energy landscape.

Additionally, there are environmental concerns associated with the development of solar farms. While solar energy is considered a clean and renewable resource, the construction of large solar installations can have environmental implications. These include potential impacts on local wildlife habitats, land use changes, where approaches like agrivoltaics can co-locate farming and solar, and the ecological effects of large-scale land clearing. As solar projects expand, balancing the benefits of renewable energy with the need to protect natural ecosystems becomes increasingly important.

Another significant challenge is the integration of solar power into Alberta's existing energy grid. Solar energy production is variable and dependent on weather conditions, especially with Alberta's limited hydro capacity for flexibility, which can create difficulties in maintaining a stable and reliable energy supply. The need for infrastructure upgrades and energy storage solutions is crucial to address these challenges and ensure that solar power can be effectively utilized alongside other energy sources.

Despite these challenges, the Alberta government remains committed to advancing solar energy as a key component of its renewable energy strategy. Recent initiatives include financial incentives and support programs aimed at encouraging investment in solar projects and supporting a renewable energy surge that could power thousands of jobs across Alberta today. These measures are designed to help offset the high costs associated with solar installations and make the technology more accessible to businesses and homeowners alike.

Local communities and businesses are also playing a role in the growth of solar energy in Alberta. Many are exploring opportunities to invest in solar power as a means of reducing energy costs and supporting sustainability efforts and, increasingly, to sell renewable energy into the market as demand grows. These smaller-scale projects contribute to the overall expansion of solar energy and demonstrate the potential for widespread adoption across the province.

The Alberta government has also been working to address the environmental concerns associated with solar energy development. Efforts are underway to implement best practices for minimizing environmental impacts and ensuring that solar projects are developed in an environmentally responsible manner. This includes conducting environmental assessments and working with stakeholders to address potential issues before projects are approved and built.

In summary, while Alberta's solar energy initiatives hold promise for advancing the province's clean energy goals, they are also met with significant financial and environmental challenges. Addressing these issues will be crucial to the successful expansion of solar power in Alberta. The government's ongoing efforts to support solar projects through incentives and infrastructure improvements, coupled with responsible environmental practices, will play a key role in determining the future of solar energy in the province.

New Hampshire rejects Quebec-Massachusetts transmission proposal

Northern Pass Project faces rejection by New Hampshire regulators, halting Hydro-Quebec clean energy transmission lines to Massachusetts; Eversource vows appeal as the Site Evaluation Committee cites development concerns and alternative routes through Vermont and Maine.

 

Key Points

A project to transmit Hydro-Quebec power to Massachusetts via New Hampshire, recently rejected by state regulators.

✅ New Hampshire SEC denied the transmission application

✅ Up to 9.45 TWh yearly from Hydro-Quebec to Massachusetts

✅ Eversource plans appeal; alternative routes via Vermont, Maine

 

Regulators in the state of New Hampshire on Thursday rejected a major electricity project being piloted by Quebec’s hydro utility and its American partner, Eversource.

Members of New Hampshire’s Site Evaluation Committee unanimously denied an application for the Northern Pass project a week after the state of Massachusetts green-lit the proposal.

Both states had to accept the project, as the transmission lines were to bring up to 9.45 terawatt hours of electricity per year from Quebec’s hydroelectric plants to Massachusetts as part of Hydro-Quebec’s export bid to New England, through New Hampshire.

The 20-year proposal was to be the biggest export contract in Hydro-Quebec’s history, in a region where Connecticut is leading a market overhaul that could affect pricing, and would generate up to $500 million in annual revenues for the provincial utility.

Hydro-Quebec’s U.S. partner, Eversource, said in a new release it was “shocked and outraged” by the New Hampshire regulators’ decision and suggested it would appeal.

“This decision sends a chilling message to any energy project contemplating development in the Granite State,” said Eversource. “We will be seeking reconsideration of the SEC’s decision, as well as reviewing all options for moving this critical clean energy project forward, including lessons from electricity corridor construction in Maine.”

The New Hampshire Union Leader reported Thursday the seven members of the evaluation committee said the project’s promoters couldn’t demonstrate the proposed energy transport lines wouldn’t interfere with the region’s orderly development.

Hydro-Quebec spokesman Serge Abergel said the decision wasn’t great news but it didn’t put a end to the negotiations between the company and the state of Massachusetts.

The hydro utility had proposed alternatives routes through Vermont and Maine amid a 145-mile transmission line debate over the corridor should the original plan fall through.

“There is a provision included in the process in the advent of an impasse, which allows Massachusetts to go back and choose the next candidate on the list,” Abergel said in an interview. “There are still cards left on the table.”

Electric Cooperatives, The Lone Shining Utility Star Of The Texas 2021 Winter Storm

Texas Electric Cooperatives outperformed during Winter Storm Uri, with higher customer satisfaction, equitable rolling blackouts, and stronger grid reliability compared to deregulated markets, according to ERCOT-area survey data of regulated utilities and commercial providers.

 

Key Points

Member-owned utilities in Texas delivering power, noted for reliability and fair outages during Winter Storm Uri.

✅ Member-owned, regulated utilities serving local communities

✅ Rated higher for blackout management and communication

✅ Operate outside deregulated markets; align incentives with users

 

Winter Storm Uri began to hit parts of Texas on February 13, 2021 and its onslaught left close to 4.5 million Texas homes and businesses without power, and many faced power and water disruptions at its peak. By some accounts, the preliminary number of deaths attributed to the storm is nearly 200, and the economic toll for the Lone Star State is estimated to be as high as $295 billion. 

The more than two-thirds of Texans who lost power during this devastating storm were notably more negative than positive in their evaluation of the performance of their local electric utility, mirrored by a rise in electricity complaints statewide, with one exception. That exception are the members of the more than 60 electric cooperatives operating within the Texas Interconnection electrical grid, which, in sharp contrast to the customers of the commercial utilities that provide power to the majority of Texans, gave their local utility a positive evaluation related to its performance during the storm.

In order to study Winter Storm Uri’s impact on Texas, the Hobby School of Public Affairs at the University of Houston conducted an online survey during the first half of March of residents 18 and older who live in the 213 counties (91.5% of the state population) served by the Texas power grid, which is managed by the Electric Reliability Council of Texas (ERCOT). 

Three-quarters of the survey population (75%) live in areas with a deregulated utility market, where a specified transmission and delivery utility by region is responsible for delivering the electricity (purchased from one of a myriad of private companies by the consumer) to homes and businesses. The four main utility providers are Oncor, CenterPoint CNP -2.2%, American Electric Power (AEP) North, and American Electric Power (AEP) Central. 

The other 25% of the survey population live in areas with regulated markets, where a single company is responsible for both delivering the electricity to homes and businesses and serves as the only source from which electricity is purchased. Municipal-owned and operated utilities (e.g., Austin Energy, Bryan Texas Utilities, Burnet Electric Department, Denton Municipal Electric, New Braunfels Utilities, San Antonio’s CPS Energy CMS -2.1%) serve 73% of the regulated market. Electric cooperatives (e.g., Bluebonnet Electric Cooperative, Central Texas Electric Cooperative, Guadalupe Valley Cooperative, Lamb County Electric Cooperative, Pedernales Electricity Cooperative, Wood County Electric Cooperative) serve one-fifth of this market (21%), with private companies accounting for 6% of the regulated market.

The overall distribution of the survey population by electric utility providers is: Oncor (38%), CenterPoint (21%), municipal-owned utilities (18%), AEP Central & AEP North combined (12%), electric cooperatives (6%), other providers in the deregulated market (4%) and other providers in the regulated market (1%). 

There were no noteworthy differences among the 31% of Texans who did not lose power during the winter storm in regard to their evaluations of their local electricity provider or their belief that the power cuts in their locale were carried out in an equitable manner.  

However, among the 69% of Texans who lost power, those served by electric cooperatives in the regulated market and those served by private electric utilities in the deregulated market differed notably regarding their evaluation of the performance of their local electric utility, both in regard to their management of the rolling blackouts, amid debates over market reforms to avoid blackouts, and to their overall performance during the winter storm. Those Texans who lost power and are served by electric cooperatives in a regulated market had a significantly more positive evaluation of the performance of their local electric utility than did those Texans who lost power and are served by a private company in a deregulated electricity market. 

For example, only 24% of Texans served by electric cooperatives had a negative evaluation of their local electric utility’s overall performance during the winter storm, compared to 55%, 56% and 61% of those served by AEP, Oncor and CenterPoint respectively. A slightly smaller proportion of Texans served by electric cooperatives (22%) had a negative evaluation of their local electric utility’s performance managing the rolling blackouts during the winter storm, compared to 58%, 61% and 71% of Texans served by Oncor, AEP and CenterPoint, respectively.

Texans served by electric cooperatives in regulated markets were more likely to agree that the power cuts in their local area were carried out in an equitable manner compared to Texans served by commercial electricity utilities in deregulated markets. More than half (52%) of those served by an electric cooperative agreed that power cuts during the winter storm in their area were carried out in an equitable manner, compared to only 26%, 23% and 23% of those served by Oncor, AEP and CenterPoint respectively

The survey data did not allow us to provide a conclusive explanation as to why the performance during the winter storm by electric cooperatives (and to a much lesser extent municipal utilities) in the regulated markets was viewed more favorably by their customers than was the performance of the private companies in the deregulated markets viewed by their customers. Yet here are three, far from exhaustive, possible explanations.

First, electric cooperatives might have performed better (based on objective empirical metrics) during the winter storm, perhaps because they are more committed to their customers, who are effectively their bosses. .  

Second, members of electric cooperatives may believe their electric utility prioritizes their interests more than do customers of commercial electric utilities and therefore, even if equal empirical performance were the case, are more likely to rate their electric utility in a positive manner than are customers of commercial utilities.  

Third, regulated electric utilities where a single entity is responsible for the commercialization, transmission and distribution of electricity might be better able to respond to the type of challenges presented by the February 2021 winter storm than are deregulated electric utilities where one entity is responsible for commercialization and another is responsible for transmission and distribution, aligning with calls to improve electricity reliability across Texas.

Other explanations for these findings may exist, which in addition to the three posited above, await future empirical verification via new and more comprehensive studies designed specifically to study electric cooperatives, large commercial utilities, and the incentives that these entities face under the regulatory system governing production, commercialization and distribution of electricity, including rulings that some plants are exempt from providing electricity in emergencies under state law. 

Still, opinion about electricity providers during Winter Storm Uri is clear: Texans served by regulated electricity markets, especially by electric cooperatives, were much more satisfied with their providers’ performance than were those in deregulated markets. Throughout its history, Texas has staunchly supported the free market. Could Winter Storm Uri change this propensity, or will attempts to regulate electricity lessen as the memories of the storm’s havoc fades? With a hotter summer predicted to be on the horizon in 2021 and growing awareness of severe heat blackout risks, we may soon get an answer.
