-- The year 2007 treated electrical utilities and their customers coldly.

For both, the year basically started and ended the same - significant ice storms wrecked electrical lines and customers' homes. In between, electricity providers were handed a setback by Oklahoma's Corporation Commission when it ruled against the companies' proposal to build a coal-fired power plant at Red Rock.

Meanwhile, motorists paid more at the pump. The last time prices for a gallon of unleaded gas in Oklahoma cost less than at least $2 was the final week of January 2007.

An ice storm struck southeastern Oklahoma in January 2007, leaving more than 125,000 customers without power.

Outages took more than a week to repair for some. Then in December, another ice storm struck, this time leaving more than 640,000 customers without power. Some still were without electricity just recently as they waited for their electrical service entrances on their homes to be repaired so power could be restored. An effort by state officials to get a disaster declaration to help homeowners with those repairs from the earlier storm failed.

In the latter storm, though, they worked with the Federal Emergency Management Agency to create a program where cities could hire electricians to make the repairs on private homes, paying the workers $500 for each job they completed.

Through Dec. 26, Tulsa's program had restored power to 2,856 homes and had work orders for repairs at 533 more. Oklahoma City's program started at about the same time.

A number of applicants could not be obtained from that city on December 31. State officials say the program, the first of its kind, likely will become a fixture in federal response plans for future storms.

To most, it appeared arguments in the case before Oklahoma's Corporation Commission to build a new power plant near Red Rock revolved around whether it should be fueled by coal or by natural gas. On one side were Oklahoma's electric providers - Oklahoma Gas and Electric Co., Public Service Co. of Oklahoma and the Oklahoma Municipal Power Authority - while environmentalists and Chesapeake Energy Corp. were on the other.

But governmental red tape decided this case, and it didn't go the way the utilities hoped it would. At least one commissioner decided the companies had not effectively demonstrated the additional power was needed. Also, the commission had not developed formal rules to pre-approve electrical generation plants even though a law requiring pre-approval ha been around since 2005. The $1.87 billion, 950-megawatt plant would have been the largest construction project in state history.

A consortium of power producers had proposed the 950-megawatt plant that would burn coal shipped to Red Rock from Wyoming. Electrical utility spokesmen predicted the decision would create higher electrical rates for customers.

Consumers didn't see low gas prices during 2007, and they paid more for it that year than they did in 2006. During 2007, they paid an average of about $2.70 a gallon for regular unleaded gas. In 2006, they paid an average of about $2.40 a gallon for regular unleaded gas.

Australia PM rules out taxpayer funded power plants amid energy battle

ACCC energy underwriting guarantee proposes government-backed certainty for new generation, cutting electricity prices and supporting gas, pumped hydro, renewables, batteries, and potentially coal-fired power, addressing market failure without direct subsidies.

 

Key Points

A tech-neutral, government-backed plan underwriting new generation revenue to increase certainty and cut power prices.

✅ Government guarantee provides a revenue floor for new generators.

✅ Technology neutral: coal, gas, renewables, pumped hydro, batteries.

✅ Intended to reduce bills by up to $400 and address market failure.

 

Australian Taxpayers won't directly fund any new power plants despite some Coalition MPs seizing on a new report to call for a coal-fired power station.

The Australian Competition and Consumer Commission recommended the government give financial certainty to new power plants, guaranteeing energy will be bought at a cheap price if it can't be sold, as part of an electricity market plan to avoid threats to supply.

It's part of a bid to cut up to $400 a year from average household power prices.

Prime Minister Malcolm Turnbull said the finance proposal had merit, but he ruled out directly funding specific types of power generation.

"We are not in the business of subsidising one technology or another," he told reporters in Queensland today.

"We've done enough of that. Frankly, there's been too much of that."

Renewable subsidies, designed in the 1990s to make solar and wind technology more affordable, have worked and will end in 2020.

Some Coalition MPs claim the ACCC's recommendation to underwrite power generation is vindication for their push to build new coal-fired power plants.

But ACCC chair Rod Sims said no companies had proposed building new coal plants - instead they're trying to build new gas projects, pumped hydro or renewable projects.

Opposition Leader Bill Shorten said Mr Turnbull was offering solutions years away, having overseen a rise in power prices over the past year.

"You don't just go down to K-Mart and get a coal-fired power station off the shelf," Mr Shorten told reporters, admitting he had not read the ACCC report.

Energy Minister Josh Frydenberg said the recommendation to underwrite new power generators had a lot of merit, as it would address a market failure highlighted by AEMO warnings about reduced reserves.

"What they're saying is the government needs to step in here to provide some sort of assurance," Mr Frydenberg told 9NEWS today.

He said that could include coal, gas, renewable energy or battery storage.

Deputy Nationals leader Bridget McKenzie said science should determine which technology would get the best outcomes for power bills, with a scrapping coal report suggesting it can be costly.

Mr Turnbull said there was strong support for the vast majority of the ACCC's 56 recommendations, but the government would carefully consider the report, which sets out a blueprint to cut electricity bills by 25 percent.

Acting Greens leader Adam Bandt said Australia should exit coal-fired power in favour of renewable energy to cut pollution.

In contrast, Canada has seen the Stop the Shock campaign advocate a return to coal power in some provinces.

The Australian Energy Council, which represents 21 major energy companies, said the government should consult on changes to avoid "unintended consequences".

Toronto Power Outages Persist for Hundreds After Spring Storm

Toronto Hydro Storm Outages continue after strong winds and heavy rain, with crews restoring power, clearing debris and downed lines. Safety alerts and real-time updates guide affected neighborhoods via website and social media.

 

Key Points

Toronto Hydro Storm Outages are weather-related power cuts; crews restore service safely and share public updates.

✅ Crews prioritize areas with severe damage and limited access

✅ Report downed power lines; keep a safe distance

✅ Check website and social media for restoration updates

 

In the aftermath of a powerful spring storm that swept through Toronto on Tuesday, approximately 400 customers remain without power as of Sunday. The storm, which brought strong winds and heavy rain that caused severe flooding in some areas, led to significant damage across the city, including downed trees and power lines. Toronto Hydro crews have been working tirelessly to restore service, similar to efforts by Sudbury Hydro crews in Northern Ontario, focusing on areas with the most severe damage. While many customers have had their power restored, the remaining outages are concentrated in neighborhoods where access is challenging due to debris and fallen infrastructure.

Toronto Hydro has assured residents that restoration efforts are ongoing and that they are prioritizing safety and efficiency, in step with recovery from damaging storms in Ontario across the province. The utility company has urged residents to report any downed power lines and to avoid approaching them, as they may still be live and dangerous, and notes that utilities sometimes rely on mutual aid deployments to speed restoration in large-scale events. Additionally, Toronto Hydro has been providing updates through their website and social media channels, keeping the public informed about the status of power restoration in affected areas.

The storm's impact has also led to disruptions in other services, and power outages in London disrupted morning routines for thousands earlier in the week. Some public transportation routes experienced delays due to debris on tracks, and several schools in the affected areas were temporarily closed. City officials are coordinating with various agencies to address these issues and ensure that services return to normal as quickly as possible, even as Quebec contends with widespread power outages after severe windstorms.

Residents are advised to stay updated on the situation through official channels and to exercise caution when traveling in storm-affected areas. Toronto Hydro continues to work diligently to restore power to all customers and appreciates the public's patience during this challenging time, a challenge echoed when Texas utilities struggled to restore power during Hurricane Harvey.

Hydropower Plants to Support Solar and Wind Energy

Solar-Wind-Water West Africa integrates hydropower with solar and wind to boost grid flexibility, clean electricity, and decarbonization, leveraging the West African Power Pool and climate data modeling reported in Nature Sustainability.

 

Key Points

A strategy using hydropower to balance solar and wind, enabling reliable, low-carbon electricity across West Africa.

✅ Hydropower dispatch covers solar and wind shortfalls.

✅ Regional interconnection via West African Power Pool.

✅ Cuts CO2 versus gas while limiting new dam projects.

 

Hydropower plants can support solar and wind power, rather unpredictable by nature, in a climate-friendly manner. A new study in the scientific journal Nature Sustainability has now mapped the potential for such "solar-wind-water" strategies for West Africa: an important region where the power sector is still under development, amid IEA investment needs for universal access, and where generation capacity and power grids will be greatly expanded in the coming years. "Countries in West Africa therefore now have the opportunity to plan this expansion according to strategies that rely on modern, climate-friendly energy generation," says Sebastian Sterl, energy and climate scientist at Vrije Universiteit Brussel and KU Leuven and lead author of the study. "A completely different situation from Europe, where power supply has been dependent on polluting power plants for many decades - which many countries now want to rid themselves of."

Solar and wind power generation is increasing worldwide and becoming cheaper and cheaper. This helps to keep climate targets in sight, but also poses challenges. For instance, critics often argue that these energy sources are too unpredictable and variable to be part of a reliable electricity mix on a large scale, though combining multiple resources can enhance project performance.

"Indeed, our electricity systems will have to become much more flexible if we are to feed large amounts of solar and wind power into the grid. Flexibility is currently mostly provided by gas power plants. Unfortunately, these cause a lot of CO2 emissions," says Sebastian Sterl, energy and climate expert at Vrije Universiteit Brussel (VUB) and KU Leuven. "But in many countries, hydropower plants can be a fossil fuel-free alternative to support solar and wind energy. After all, hydropower plants can be dispatched at times when insufficient solar and wind power is available."

The research team, composed of experts from VUB, KU Leuven, the International Renewable Energy Agency (IRENA), and Climate Analytics, designed a new computer model for their study, running on detailed water, weather and climate data. They used this model to investigate how renewable power sources in West Africa could be exploited as effectively as possible for a reliable power supply, even without large-scale storage, in line with World Bank support for wind in developing countries. All this without losing sight of the environmental impact of large hydropower plants.

"This is far from trivial to calculate," says Prof. Wim Thiery, climate scientist at the VUB, who was also involved in the study. "Hydroelectric power stations in West Africa depend on the monsoon; in the dry season they run on their reserves. Both sun and wind, as well as power requirements, have their own typical hourly, daily and seasonal patterns. Solar, wind and hydropower all vary from year to year and may be impacted by climate change, including projections that wind resources shift southward in coming years. In addition, their potential is spatially very unevenly distributed."

West African Power Pool

The study demonstrates that it will be particularly important to create a "West African Power Pool", a regional interconnection of national power grids to serve as a path to universal electricity access across the region. Countries with a tropical climate, such as Ghana and the Ivory Coast, typically have a lot of potential for hydropower and quite high solar radiation, but hardly any wind. The drier and more desert-like countries, such as Senegal and Niger, hardly have any opportunities for hydropower, but receive more sunlight and more wind. The potential for reliable, clean power generation based on solar and wind power, supported by flexibly dispatched hydropower, increases by more than 30% when countries can share their potential regionally, the researchers discovered.

All measures taken together would allow roughly 60% of the current electricity demand in West Africa to be met with complementary renewable sources, despite concerns about slow greening of Africa's electricity, of which roughly half would be solar and wind power and the other half hydropower - without the need for large-scale battery or other storage plants. According to the study, within a few years, the cost of solar and wind power generation in West Africa is also expected to drop to such an extent that the proposed solar-wind-water strategies will provide cheaper electricity than gas-fired power plants, which currently still account for more than half of all electricity supply in West Africa.

Better ecological footprint

Hydropower plants can have a considerable negative impact on local ecology. In many developing countries, piles of controversial plans for new hydropower plants have been proposed. The study can help to make future investments in hydropower more sustainable. "By using existing and planned hydropower plants as optimally as possible to massively support solar and wind energy, one can at the same time make certain new dams superfluous," says Sterl. "This way two birds can be caught with one stone. Simultaneously, one avoids CO2 emissions from gas-fired power stations and the environmental impact of hydropower overexploitation."

Global relevance

The methods developed for the study are easily transferable to other regions, and the research has worldwide relevance, as shown by a US 80% study on high variable renewable shares. Sterl: "Nearly all regions with a lot of hydropower, or hydropower potential, could use it to compensate shortfalls in solar and wind power." Various European countries, with Norway at the front, have shown increased interest in recent years to deploy their hydropower to support solar and wind power in EU countries. Exporting Norwegian hydropower during times when other countries undergo solar and wind power shortfalls, the European energy transition can be advanced.

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.

WY Utility's First Wind Farm Faces Replacement

Foote Creek I Wind Farm Repowering upgrades Wyoming turbines with new nacelles, towers, and blades, cutting 68 units to 12 while sustaining 41.6 MW, under PacifiCorp and Rocky Mountain Power's Energy Vision 2020 plan.

 

Key Points

Replacement at Foote Creek Rim I, cutting to 12 turbines while sustaining about 41.6 MW using modern 2-4.2 MW units.

✅ 12 turbines replace 68, output steady near 41.6 MW

✅ New nacelles, towers, blades; taller 500 ft turbines

✅ Part of PacifiCorp Energy Vision 2020 and Gateway West

 

A Wyoming utility company has filed a permit to replace its first wind farm—originally commissioned in 1998, composed of over 65 turbines—amid new gas capacity competing with nuclear in Ohio, located at Foote Creek Rim I. The replacement would downsize the number of turbines to 12, which would still generate roughly the same energy output.

According to the Star Tribune, PacifiCorp’s new installation would involve new nacelles, new towers and new blades. The permit was filed with Carbon County.

 

New WY Wind Farm

The replacement wind turbines will stand more than twice as tall as the old: Those currently installed stand 200 feet tall, whereas their replacements will tower closer to 500 feet. Though this move is part of the company’s overall plan to expand its state wind fleet as some utilities respond to declining coal returns in the Midwest, the work going into the Foote Creek site is somewhat special, noted David Eskelsen, spokesperson for Rocky Mountain Power, the western arm of PacifiCorp.

“Foote Creek I repowering is somewhat different from the repowering projects announced in the (Energy Vision) 2020 initiative,” he said. “Foote Creek is a complete replacement of the existing 68 foundations, towers, turbine nacelles and rotors (blades).”

Currently, the turbines at Foote Creek have 600 kilowatts capacity each; the replacements’ maximum production ranges from 2 megawatts to 4.2 megawatts each, with the total output remaining steady at 41.4 megawatts, a scale similar to a 30-megawatt wind expansion in Eastern Kings, though there will be a slight capacity increase to 41.6 megawatts, according to the Star Tribune.

As part of the wind farm repowering initiative, PacifiCorp is to become full owner and operator of the Foote Creek site. When the farm was originally built, an Oregon-based water and electric board was 21 percent owner; 37 percent of the project’s output was tied into a contract with the Bonneville Power Administration.

Otherwise, PacifiCorp is moving to further expand its state wind fleet in line with initiatives like doubling renewable electricity by 2030 in Saskatchewan, with the addition of three new wind farms—to be located in Carbon, Albany and Converse counties—which may add up to 1,150 megawatts of power.

According to PacifiCorp, the company has more than 1,000 megawatts of owned wind generation capability, along with long-term purchase agreements for more than 600 megawatts from other wind farms owned by other entities. Energy Vision 2020 refers to a $3.5 billion investment and company move that is looking to upgrade the company's existing wind fleet with newer technology, adding 1,150 megawatts of new wind resources by 2020 and a a new 140-mile Gateway West transmission segment in Wyoming, comparable to a transmission project in Missouri just energized.

Emissions rise 2% in Australia amid increased pollution from electricity and transport

Australia's greenhouse gas emissions rose in Q2 as electricity and transport pollution increased, despite renewable energy growth. Net zero targets, carbon dioxide equivalent metrics, and land use changes underscore mixed trends in decarbonisation.

 

Key Points

About 499-500 Mt CO2-e annually, with a 2% quarterly rise led by electricity and transport.

✅ Q2 emissions rose to 127 Mt from 124.4 Mt seasonally adjusted

✅ Electricity sector up to 41.6 Mt; transport added nearly 1 Mt

✅ Land use remains a net sink; renewables expanded capacity

 

Australia’s greenhouse gas emissions rose in the June quarter by about 2% as pollution from the electricity sector and transport increased.

Figures released on Tuesday by the Morrison government showed that on a year to year basis, emissions for the 12 months to last June totalled 498.9m tonnes of carbon dioxide equivalent. That tally was down 2.1%, or 10.8m tonnes compared with the same period a year earlier.

However, on a seasonally adjusted quarterly basis, emissions increased to 127m tonnes, or just over 2%, from the 124.4m tonnes reported in the March quarter. For the year to March, emissions totalled 494.2m tonnes, underscoring the pickup in pollution in the more recent quarter even as global coal power declines worldwide.

A stable pollution rate, if not a rising one, is also implied by the government’s release of preliminary figures for the September quarter. They point to 125m tonnes of emissions in trend terms for the July-September months, bringing the year to September total to about 500m tonnes, the latest report said.

The government has made much of Australia “meeting and beating” climate targets. However, the latest statistics show mostly emissions are not in decline despite its pledge ahead of the Glasgow climate summit that the country would hit net zero by 2050, and AEMO says supply can remain uninterrupted as coal phases out over the next three decades.

“Nothing’s happening except for the electricity sector,” said Hugh Saddler, an honorary associate professor at the Australian National University. Once Covid curbs on the economy eased, such as during the current quarter, emission sources such as from transport will show a rise, he predicted.

Falling costs for new wind and solar farms, with the IEA naming solar the cheapest in history worldwide, are pushing coal and gas out of electricity generation, as well as pushing down power prices. In seasonally adjusted terms, though, emissions for that sector rose from 39.7m tonnes the March quarter to 41.6m in the June one.

Most other sectors were steady, with pollution from transport adding almost 1m tonnes in the June quarter.

On an annual basis, a 500m tonnes tally is the lowest since records began in the 1990s, and IEA reported global emissions flatlined in 2019 for context. That lower trajectory, though, is lower due much to the land sector remaining a net sink even as some experts raise questions about the true trends when it comes to land clearing.

According to the government, this sector – known as land use, land-use change and forestry – amounted to a net reduction of emissions of 24.4m tonnes, or almost negative 5% of the national total, in the year to June.

“The magnitude of this net sink has decreased by 0.6% (0.2 Mt CO2-e) on the previous 12 months due to an increase in emissions from agricultural soils, partially offset by a continuing decline in land clearing emissions,” the latest report said.

For its part, the government also touted the increase of renewable energy, as seen in Canada's electricity progress too, as central to driving emissions lower.

“Since 2017, Australia’s consumption of renewable energy has grown at a compound annual rate of 4.6%, with more than $40bn invested in Australia’s renewable energy sector,” Angus Taylor, the federal energy minister said, while UK net zero policy changes show a different approach. “Last year, Australia deployed new solar and wind at eight times the global per capita average.”

ANU’s Saddler said the main driver had been the 2020 Renewable Energy Target that the Coalition government had cut, and had anyway been implemented “a very considerable time ago”.

Tim Baxter, the Climate Council’s senior researcher, said “the time for leaning on the achievements of others is long since past”.

“We need a federal government willing to step up on emissions reductions and take charge with real policy, not wishlists,” he said, referring to the government’s net zero plan to rely on technologies to cut pollution in pursuit of a sustainable electric planet in practice, some of which don’t exist now.
