To ensure a profitable survival by producers of motors, generators, land transportation motors, fractional and integral motor generator sets, and components in a declining durable goods market, the emphasis must be on improving output per man-hour worked, thereby trimming labor costs and boosting profits.

Too many manufacturers of motors, generators, and components are satisfied with only an average return of about 3% on sales, but this is not sufficient for longevity, said Dr. Woodruff Imberman, a leading management consultant, in his remarks to a meeting of motors, generators, and components manufacturers at the recent IEEE PES Transmission and Distribution Conference at McCormick Convention Center in Chicago.

Dr. Imberman emphasized the use of various productivity enhancement programs by certain manufacturers, which stimulate their workforces to produce more efficiently with quality output. This is of particular importance where there are Hispanic workers. The efficient producers, said Dr. Imberman, enjoy as much as 10-12% profit margin on sales, despite the mounting import competitions, and they do this mainly by concentrating on a variety of bonus production programs which stimulate the workforce, particularly with Hispanic workers.

The leading productivity improvement program is Gainsharing, which increases employee income and company profits. In response for further information, Dr. Imberman cited a lecture which he delivered at Indiana University and published as an article entitled, “All You Ever Wanted to Know About Gainsharing but Were Afraid to Ask,” copies of which he distributed to the meeting, and may be available to others by request to imbanddef@aol.com. There is no reason to fear a recession by producers who concentrate on efficient productivity procedures, thereby shaving costs and boosting profits, concluded Dr. Imberman.

✅ Enhances sustainability and lowers operating costs

 

In a significant step towards sustainable mining practices, Rio Tinto has completed the largest off-grid solar power plant in Canada’s Northwest Territories. This groundbreaking achievement not only highlights the company's commitment to renewable energy, as Canada nears 5 GW of solar capacity nationwide, but also sets a new standard for the mining industry in remote and off-grid locations.

Located in the remote Diavik Diamond Mine, approximately 220 kilometers south of the Arctic Circle, Rio Tinto's off-grid solar power plant represents a technological feat in harnessing renewable energy in challenging environments. The plant is designed to reduce reliance on diesel fuel, traditionally used to power the mine's operations, and mitigate carbon emissions associated with mining activities.

The decision to build the solar power plant aligns with Rio Tinto's broader sustainability goals and commitment to reducing its environmental footprint. By integrating renewable energy sources like solar power, a strategy that renewable developers say leads to better, more resilient projects, the company aims to enhance energy efficiency, lower operational costs, and contribute to global efforts to combat climate change.

The Diavik Diamond Mine, jointly owned by Rio Tinto and Dominion Diamond Mines, operates in a remote region where access to traditional energy infrastructure is limited, and where, despite lagging solar demand in Canada, off-grid solutions are increasingly vital for reliability. Historically, diesel generators have been the primary source of power for the mine's operations, posing logistical challenges and environmental impacts due to fuel transportation and combustion.

Rio Tinto's investment in the off-grid solar power plant addresses these challenges by leveraging abundant sunlight in the Northwest Territories to generate clean electricity directly at the mine site. The solar array, equipped with advanced photovoltaic technology, which mirrors deployments such as Arvato's first solar plant in other sectors, is capable of producing a significant portion of the mine's electricity needs during peak solar hours, reducing reliance on diesel generators and lowering overall carbon emissions.

Moreover, the completion of the largest off-grid solar power plant in Canada's Northwest Territories underscores the feasibility and scalability of renewable energy solutions, from rooftop arrays like Edmonton's largest rooftop solar to off-grid systems in remote and resource-intensive industries like mining. The success of this project serves as a model for other mining companies seeking to enhance sustainability practices and operational resilience in challenging geographical locations.

Beyond environmental benefits, Rio Tinto's initiative is expected to have positive economic and social impacts on the local community. By reducing diesel consumption, the company mitigates air pollution and noise levels associated with mining operations, improving environmental quality and contributing to the well-being of nearby residents and wildlife.

Looking ahead, Rio Tinto's investment in renewable energy at the Diavik Diamond Mine sets a precedent for responsible resource development and sustainable mining practices in Canada, where solar growth in Alberta is accelerating, and globally. As the mining industry continues to evolve, integrating renewable energy solutions like off-grid solar power plants will play a crucial role in achieving long-term environmental sustainability and operational efficiency.

In conclusion, Rio Tinto's completion of the largest off-grid solar power plant in Canada's Northwest Territories marks a significant milestone in the mining industry's transition towards renewable energy. By harnessing solar power to reduce reliance on diesel generators, the company not only improves operational efficiency and environmental stewardship but also adds to momentum from corporate power purchase agreements like RBC's Alberta solar deal, setting a positive example for sustainable development in remote regions. As global demand for responsible mining practices grows, initiatives like Rio Tinto's off-grid solar project demonstrate the potential of renewable energy to drive positive change in resource-intensive industries.

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.

A goodwill gesture over electricity sows discord in Lebanon

Lebanon Power Barge Controversy spotlights Karadeniz Energy's Esra Sultan, Lebanon's electricity crisis, prolonged blackouts, and sectarian politics as Amal and Hezbollah clash over Zahrani vs Jiyeh docking and allocation across regions.

 

Key Points

A political dispute over the Esra Sultan power ship, its docking, and power allocation amid Lebanon's chronic blackouts.

✅ Karadeniz Energy lent a third barge at below-market rates.

✅ Docking disputes: Zahrani refused; Jiyeh limited; Zouq connected.

✅ Amal vs Hezbollah split exposes sectarian energy politics.

 

It was supposed to be a goodwill gesture from an energy company in Turkey.

This summer, the Karadeniz Energy Group lent Lebanon a floating power station to generate electricity at below-market rates to help ease the strain on the country's woefully undermaintained power sector.

Instead, the barge's arrival opened a Pandora's box of partisan mudslinging in a country hobbled by political sectarianism and dysfunction.

There have been rows over where it should dock, how to allocate its 235 megawatts of power, and even what to call the barge, echoing controversies like the Maine electric line debate that pit local politics against energy needs.

It has even driven a wedge between Lebanon's two dominant parties among Shiite Muslims: Amal and the militant group Hezbollah.

Amal, which has held the parliament speaker's seat since 1992, revealed sensationally last week it had refused to allow the boat to dock in a port in the predominantly Shiite south, even though it is one of the most underserved regions of Lebanon.

Power outages in the south can stretch on for more than 12 hours a day, much like the Gaza electricity crisis, according to regional observers.

Hezbollah, which normally stands pat with Amal in political matters, issued an exceptional statement that it had nothing to do with the matter of the barge at Zahrani port. A Hezbollah lawmaker went further to say his party disagreed on the issue with Amal.

Ali Hassan Khalil, Lebanon's Finance Minister and a leading Amal party member, said southerners wanted a permanent power station, not a stop-gap solution, in an implied dig at the rival Free Patriotic Movement, a Christian party that runs the Energy Ministry.

But critics seized on the statement as confirmation that Amal's leaders were in bed with the operators of private generators, who have been making fortunes selling electricity during blackouts at many times the state price.

"For decades there's been nothing stopping them from building a power plant," said Mohammad Obeid, a former Amal party official, in an interview with Lebanon's Al Jadeed TV station.

"Now there's a barge that's coming for three months to provide a few more hours of electricity -- and that's the issue?"

Hassan Khalil, reached by phone, refused to comment.

Nabih Berri, Amal's chief and Lebanon's parliament speaker, who has long been the subject of critical coverage from Al Jadeed's, sued the TV channel for libel on Wednesday for its reporting.

Energy Minister Cesar Abi Khalil, a Christian, lashed out at Amal, saying the ministry even changed the barge's name from Ayse, Turkish for Aisha, a name associated in Lebanon with Sunnis, to Esra Sultan, which does not carry any Shiite or Sunni connotations, to try to get it to dock in Zahrani.

Karadeniz said the barge was renamed "out of courtesy and respect to local customs and sensitivities."

"Ayse is a very common Turkish name, where such preferences are not as sensitive as in Lebanon," it said in a statement to The Associated Press.

Finally, on July 18, the barge docked in Jiyeh, a harbour south of Beirut but north of Zahrani, and in a religiously mixed Muslim area.

But two weeks later it was unmoored again, after Abi Khalil, the energy minister, said the infrastructure at Jiyeh could only handle 30 megawatts of the Esra Sultan's 235 capacity, and upgrades such as burying subsea cables are expensive.

With Zahrani closed to the Esra Sultan, it could only go to Zouq Mikhael, a port in the Christian-dominated Kesrouan region in the north, where it was plugged to the grid Tuesday night, giving the region almost 24 hours of electricity a day.

Lebanon has been contending with rolling blackouts since the days of its 1975-1990 civil war. Successive governments have failed to agree on a permanent solution for the chronic electricity failures, largely because of profiteering, endemic corruption and lack of political will, despite periodic pushes for electricity sector reform in Lebanon over the years.

In 2013, the Energy Ministry contracted with Karadeniz to buy electricity from a pair of its barges, which are still docked in Jiyeh and Zouq Mikhael.

This summer, Abi Khalil signed a new contract with Karadeniz to keep the barges for another three years. As part of the deal, Karadeniz agreed to lend Lebanon the third barge, the Esra Sultan, to produce electricity for three months at no cost - Lebanon would just have to pay for the fuel.

The company said Lebanon's internal squabbles do not affect how long the Esra Sultan would stay in Lebanon, even amid wider sector volatility and the pandemic's impact highlighted in a recent financial update. It arrived on July 18 and it will leave on Oct. 18, it said.

California Blackouts reveal lapses in power supply

California Electricity Reliability covers grid resilience amid heat waves, rolling blackouts, renewable energy integration, resource adequacy, battery storage, natural gas peakers, ISO oversight, and peak demand management to keep homes, businesses, and industry powered.

 

Key Points

Dependable California power delivery despite heat waves, peak demand, and challenges integrating renewables into grid.

✅ Rolling blackouts revealed gaps in resource adequacy.

✅ Early evening solar drop requires fast ramping and storage.

✅ Agencies pledge planning reforms and flexible backup supply.

 

One hallmark of an advanced society is a reliable supply of electrical energy for residential, commercial and industrial consumers. Uncertainty that California electricity will be there when we need it it undermines social cohesion and economic progress, as demonstrated by the travails of poor nations with erratic energy supplies.

California got a small dose of that syndrome in mid-August when a record heat wave struck the state and utilities were ordered to impose rolling blackouts to protect the grid from melting down under heavy air conditioning demands.

Gov. Gavin Newsom quickly demanded that the three overseers of electrical service to most of the state - the Public Utilities Commission, the Energy Commission and the California Independent Service Operator – explain what went wrong.

"These blackouts, which occurred without prior warning or enough time for preparation, are unacceptable and unbefitting of the nation's largest and most innovative state," Newsom wrote. "This cannot stand. California residents and businesses deserve better from their government."

Initially, there was some fingerpointing among the three entities. The blackouts had been ordered by the California Independent System Operator, which manages the grid and its president, Steve Berberich, said he had warned the Public Utilities Commission about the potential supply shortfall facing the state.

"We have indicated in filing after filing after filing that the resource adequacy program was broken and needed to be fixed," he said. "The situation we are in could have been avoided."

However, as political heat increased, the three agencies hung together and produced a joint report that admitted to lapses of supply planning and grid management and promised steps to avoid a repeat next summer.

"The existing resource planning processes are not designed to fully address an extreme heat storm like the one experienced in mid August," their report said. "In transitioning to a reliable, clean and affordable resource mix, resource planning targets have not kept pace to lead to sufficient resources that can be relied upon to meet demand in the early evening hours. This makes balancing demand and supply more challenging."

Although California's grid had experienced greater heat-related demands in previous years, most notably 2006, managers then could draw standby power from natural gas-fired plants and import juice from other Western states when necessary.

Since then, the state has shut down a number of gas-fired plants and become more reliant on renewable but less reliable sources such as windmills and solar panels.

August's air conditioning demand peaked just as output from solar panels was declining with the setting of the sun and grid managers couldn't tap enough electrons from other sources to close the gap.

While the shift to renewables didn't, unto itself, cause the blackouts, they proved the need for a bigger cushion of backup generation or power storage in batteries or some other technology. The Public Utilities Commission, as Beberich suggested, has been somewhat lax in ordering development of backup supply.

In the aftermath of the blackouts, the state Water Resources Control Board, no doubt with direction from Newsom's office, postponed planned shutdowns of more coastal plants, which would have reduced supply flexibility even more.

Shifting to 100% renewable electricity, the state's eventual goal, while maintaining reliability will not get any easier. The state's last nuclear plant, Diablo Canyon, is ticketed for closure and demand will increase as California eliminates gasoline- and diesel-powered vehicles in favor of "zero emission vehicles" as part of its climate policies push and phases out natural gas in homes and businesses.

Politicians such as Newsom and legislators in last week's blackout hearing may endorse a carbon-free future in theory, but they know that they'll pay the price as electricity prices climb if nothing happens when Californians flip the switch.

Hydro One bends to government demands, caps CEO pay at $1.5M

Hydro One CEO Pay Cap sets executive compensation at $1.5 million under Ontario's provincial directive, linking incentives to transmission and distribution cost reductions, governance improvements, and board pay limits at the electricity utility.

 

Key Points

The Hydro One CEO Pay Cap limits pay to $1.5M, linking incentives to cost reductions and defined targets.

✅ Base salary set at $500,000 per year.

✅ Incentives capped at $1,000,000, tied to cost cuts.

✅ Board pay capped: chair $120,000; members $80,000.

 

Hydro One has agreed to cap the annual compensation of its chief executive at $1.5 million, the provincial utility said Friday, acquiescing to the demands of the Progressive Conservative government.

The CEO's base salary will be set at $500,000 per year, while short-term and long-term incentives are limited to $1 million. Performance targets under the pay plan will include the CEO's contributions to reductions in transmission and distribution costs, even as Hydro One has pursued a bill redesign to clarify charges for customers.

The framework represents a notable political victory for Premier Doug Ford, who vowed to fire Hydro One's CEO and board during the campaign and promised to reduce the annual earnings of Hydro One's board members.

In February, the province issued a directive to the board, ordering it to pay the utility's CEO no more than the $1.5 million figure it has now agreed to, as part of a broader push to lower electricity rates across Ontario.

Hydro One and the government had been at loggerheads over executive compensation, with the company refusing repeated requests to slash the CEO pay below $2,775,000. The board argued it would have difficulty recruiting suitable leaders for anything less, even as customers contend with a recovery rate that could raise hydro bills.

Further, the company agreed to pay the board chair no more than $120,000 annually and board members no more than $80,000 — figures Energy Minister Greg Rickford had outlined in his directive last month, amid calls for cleaning up Ontario's hydro mess from policy commentators.

"Hydro One's compliance with this directive allows us to move forward as a province. It sets the company on the right course for the future, proving that it can operate as a top-class electricity utility while reining in executive compensation and increasing public transparency," Rickford said in a statement issued Friday morning.

Canadian power crews head to Irma-hit Florida to help restore service

Canadian Power Crews Aid Florida after Hurricane Irma, supporting power restoration for Tampa Electric and Florida Power & Light. Hydro One and Nova Scotia Power teams provide mutual aid to speed outage repairs across communities.

 

Key Points

Mutual aid effort sending Canadian utility crews to restore power and repair outages in Florida after Hurricane Irma.

✅ Hydro One and Nova Scotia Power deploy line technicians

✅ Support for Tampa Electric and Florida Power & Light

✅ Goal: rapid power restoration and outage repairs statewide

 

Hundreds of Canadian power crews are heading to Florida to help restore power to millions of people affected by Hurricane Irma.

Two dozen Nova Scotia Power employees were en route Tampa on Tuesday morning. An additional 175 Hydro One employees from across Ontario are also heading south. Tuesday to assist after receiving a request for assistance from Tampa Electric.

Nearly 7½ million customers across five states were without power Tuesday morning as Irma — now a tropical storm — continued inland, while a power outage update from the Carolinas underscored the regional strain.

In an update On Tuesday, Florida Power & Light said its "army" of crews had already restored power to 40 per cent of the five million customers affected by Irma in the first 24 hours.

FPL said it expects to have power restored in nearly all of the eastern half of the state by the end of this coming weekend. Almost everyone should have power restored by the end of day on Sept. 22, except for areas still under water.Jason Cochrane took a flight from Halifax Stanfield International Airport along with 19 other NSP power line technicians, two supervisors and a restoration team lead, drawing on lessons from the Maritime Link first power project between Newfoundland and Nova Scotia. "It's different infrastructure than what we have to a certain extent, so there'll be a bit of a learning curve there as well," Cochrane said. "But we'll be integrated into their workforce, so we'll be assisting them to get everything put back together."

The NSP team will join 86 other Nova Scotians from their parent company, Emera, who are also heading to Tampa. Halifax-based Emera, whose regional projects include the Maritime Link, owns a subsidiary in Tampa.

"We're going to be doing anything that we can to help Tampa Electric get their customers back online," said NSP spokesperson Tiffany Chase. "We know there's been significant damage to their system as a result of that severe storm and so anything that our team can do to assist them, we want to do down in Tampa."

Crews have been told to expect to be on the ground in the U.S. for two weeks, but that could change as they get a better idea of what they're dealing with.

'It's neat to have an opportunity like this to go to another country and to help out.'- Jason Cochrane, power line technician

"It's neat to have an opportunity like this to go to another country and to help out and to get the power back on safely," said Cochrane.

Chase said she doesn't know how much the effort will cost but it will be covered by Tampa Electric. She also said Nova Scotia Power will pull its crews back if severe weather heads toward Atlantic Canada, as utilities nationwide work to adapt to climate change in their planning.
