Six leading wind turbine manufacturers signed an agreement with the Department of Energy to find ways to improve turbine design and production methods as the industry attempts to boost its contribution to the nation's electric supply, the energy agency said.

The memorandum calls for a two-year collaboration to research methods to design and fabricate more reliable turbine components; reduce installation and operating costs; address environmental and technical issues; and to develop turbine certification, workforce and grid connection standards.

Companies that signed the agreement include GE Energy, Siemens Power Generation, Vestas Wind Systems, Clipper Turbine Works, Suzlon Energy and Gamesa Corp, DOE officials said at a press conference at WindPower 2008, an annual conference and exhibit sponsored by the American Wind Energy Association in Houston.

Andy Karsner, DOE assistant secretary of energy efficiency and renewables, said the cooperative research effort between the agency and industry shows a "shared commitment" to expand wind's share of the U.S. electric supply from about 2 percent to a 20 percent target by 2030.

"To dramatically reduce greenhouse gas emissions and enhance our energy security, clean power generation at the gigawatt-scale will be necessary to expand domestic wind manufacturing base and streamline the permitting process," Karsner said.

The U.S added 5,000 megawatts of wind generation capacity last year at an estimated $9 billion, according to AWEA, as states move to mandate renewable power generation. About 1,400 MW was added in the first quarter.

Nova Scotia's last paper mill seeks new discount electricity rate

Nova Scotia Power Active Demand Control Tariff lets the utility direct Port Hawkesbury Paper load, enabling demand response, efficiency, and industrial electricity rates, while regulators assess impacts on ratepayers, grid reliability, mill viability, and savings.

 

Key Points

A four-year tariff letting the utility control the mill load for demand response, efficiency, and lower costs.

✅ Utility can increase or reduce daily consumption at the mill

✅ Projected savings of $10M annually for other ratepayers to 2023

✅ Regulators reviewing cost allocation, monitoring, and viability

 

Nova Scotia Power is scheduled to appear before government regulators Tuesday morning seeking approval for a unique discount rate for its largest customer.

Under the four-year plan, Nova Scotia Power would control the supply of electricity to Port Hawkesbury Paper, a move referenced in a grid operations report that urges changes, with the right to direct the company to increase or reduce daily consumption throughout the year.

The rate proposal is supported by the mill, which says it needs to lower its power bill to keep its operation viable.

The rate went into effect on Jan. 1 on a temporary basis, pending the outcome of a hearing this week before the Nova Scotia Utility and Review Board, amid broader calls for an independent body to lead electricity planning.

The mill accounts for 10 per cent of the provincial electricity load, even as a neighbouring utility pursues more Quebec power for the region, producing glossy paper used in magazines and catalogs.

Nova Scotia Power says controlling how much electricity the mill uses — and when — will allow it to operate the system much more efficiently, as it expands biomass generation initiatives, saving other customers $10 million a year until the rate expires in 2023.

Ceding control 'not an easy decision'
In its opening statement that was filed in advance, Port Hawkesbury Paper said ceding the control of its electrical supply to Nova Scotia Power was "not an easy decision" to make, but the company is confident the arrangement will work.

In September 2019, Nova Scotia Power and the mill jointly applied for an "extra large active demand control tariff," which would provide electricity to the mill for about $61 per megawatt hour, well below the full cost of generating the electricity.

The utility said "fully allocating costs" would result in "prices in excess of $80/MWh ... and [would] not [be] financially viable for the mill."

In its statement, Port Hawkesbury Paper said since the initial filing "there have been greater near term declines in market demand and pricing for PHP's product than was forecast at that time, continuing to put pressure on our business and further highlighting the need to maintain the balance provided for in the new tariff."

Consumer advocate sees 'advantage,' but will challenge
Bill Mahody represents Nova Scotia Power's 400,000 residential customers before the review board. He wants proof the mill will pay enough toward the cost of generating the electricity it uses, amid concerns over biomass use in the province today.

"We filed evidence, as have others involved in the proceeding, that would call into question whether or not the rate design is capturing all of those costs and that will be a significant issue before the board," Mahody said.

Still, he sees value in the proposal.

"This proposed rate gives Nova Scotia Power the ability to control that sizable Port Hawkesbury Paper load to the advantage of other ratepayers, as the province pursues more wind and solar projects, because Nova Scotia Power would be reducing the costs that other ratepayers are going to face," he said.

Mahody is also calling for a mechanism to monitor whether the mill's position actually improves to the point where it could pay higher rates.

"An awful lot can change during a four-year period, with new tidal power projects underway, and I think the board ought to have the ability to check in on this and make sure that their preferential rate continues to be justified," he said.

Major employer
Port Hawkesbury Paper, owned by Stern Partners in Vancouver, has received discounted power rates since it bought the idled mill in 2012. But the "load retention tariff" as it was called, expired at the end of 2019.

Regulators have accepted Nova Scotia Power's argument that it would cost other customers more if the mill ceased to operate.

The mill said it spends between $235 million and $265 million annually, employing 330 people directly and supporting 500 other jobs indirectly.

The Nova Scotia government pledged $124 million in financial assistance as part of the reopening in 2012.

New bill would close loophole that left hundreds of Kentucky miners with cold checks

Kentucky Coal Wage Protection Bill strengthens performance bond enforcement, links Energy and Environment Cabinet and Labor Cabinet notifications, addresses Blackjewel bankruptcy fallout, safeguards unpaid miners, ties mining permits to payroll bonds, penalizes violators via revocations.

 

Key Points

A Kentucky plan to enforce wage bonds and revoke mining permits to protect miners after bankruptcies.

✅ Requires wage bonds for firms under 5 years

✅ Links Energy and Environment Cabinet and Labor Cabinet

✅ Violators face permit revocation in 90 days

 

Following the high-profile bankruptcy of a coal company that left hundreds of Kentucky miners with bad checks last month, Sen. Johnny Ray Turner (D-Prestonsburg) said he will pre-file a bill Thursday aimed at closing a loophole that allowed the company to operate in violation of state law.

The bill would also compel state agencies to determine whether other companies are currently in violation of the law, and could revoke mining permits if the companies don't comply.

Turner's bill would amend an already-existing law that requires coal and construction companies that have been operating in Kentucky for less than five years to post a performance bond to protect wages if the companies cease their operations.

Blackjewel LLC., which employed hundreds of miners in Eastern Kentucky, failed to post that bond. When it shut its mines down and filed for bankruptcy last month, it left hundreds of miners without payment for 3 weeks and one day of work.

The bond issue has sparked criticism from various state officials, including Attorney General Andy Beshear, who said Tuesday that he would investigate whether other companies are currently in violation, similar to an external investigation of utility workers in another jurisdiction.

Blackjewel issued cold checks to its employees June 28, and when the checks bounced days later, many employees were left with bank accounts overdrawn by more than $1,000. The bankruptcy left many miners and their families with concerns over upcoming bill and mortgage payments, and, as unpaid days off at utilities elsewhere show, the strain on workers can be severe, and fostered a ongoing protest that blocked a train hauling coal from one of the company's Harlan County mines.

Blackjewel had been operating in Kentucky for about two years before it filed for bankruptcy, so it should have paid the performance bond, according to state law.

David A. Dickerson, the Kentucky Labor Cabinet Secretary, said the law as it's currently written does not set up any mechanism that notifies the cabinet, or provides comparable public reporting at large utility projects elsewhere, when a company opens in Kentucky that is supposed to pay the bond.

That allowed Blackjewel to operate for two years without any protection for workers before it closed its mines. Had the company posted the bond according to state law, miners likely would have been paid for the work they had already completed, officials said.

The law requires companies to set aside enough money to cover payroll for four weeks.

Turner's bill would compel the state Energy and Environment Cabinet to notify the Labor Cabinet's Department of Workplace Standards of any application for a mining permit from a company that has been doing business in Kentucky for less than five years.

It also compels the EEC to notify the Labor Cabinet of any companies that already have permits that are subject to the bond.

"It should have already been that way, but I'm happy so our children don't have to go through this," said Jeff Willig, a former Blackjewel miner who helped launch the protest at the railroad.

Willig said he and other miners will continue to block the tracks until they receive payment for their past work.

Any company currently operating in violation of the law would have 90 days to become compliant before its mining permits are revoked. New companies that are applying for permits will be required post the bond before permits are issued.

"Hopefully it will take care of the loopholes that had been exploited by Blackjewel," Turner said.

The bill will be taken up by the legislature when it returns to session in January. It would also cover attorneys' fees if workers are forced to sue their employer to cover wages, underscoring broader worker safety concerns during health emergencies.

Turner said he has reached out to Republican leadership in the Senate, and expects the bill to have bipartisan support come January.

Turner announced the legislation at a press conference in Harlan, the county with the highest population of Blackjewel employees affected by the bankruptcy, and as prolonged utility outages after tornadoes have strained other Kentucky communities.

State rep. Angie Hatton (D-Whitesburg) was also in attendance, along with rep. Chris Fugate (R-Chavies) and state Sen. Morgan McGarvey (D-Louisville).

Hatton said the bankruptcy has had serious economic impact throughout Eastern Kentucky, including in Letcher County, which is home to more than 130 former Blackjewel workers.

"This is something that has done a lot of damage to Eastern Kentucky," Hatton said.

Hatton plans to file the same bill in the state House of Representatives.

Fugate commended community members in Harlan County and elsewhere who have banded together in support of the miners by donating children's clothing, school supplies, food and other goods, while other regions have created a coal transition fund to help displaced workers.

Mosley called the bankruptcy "totally unprecedented" and said the current performance bond law, which has been on-the-books since 1986, lacked the enforcement necessary to protect miners in bankruptcies like Blackjewel's, even as a workplace safety fine in another case shows regulatory consequences in other industries.

"There was a law, there wasn't good enough process," Mosley said.

Blackjewel received court approval to sell many of its mines last month, including many in Kentucky, to Kopper Glo Mining, LLC.

As part of the sale agreement, Kopper Glo said it would pay $450,000 to cover the past wages of Blackjewel miners, and collect a per ton fee accumulating up to $550,000 that it will also contribute to pay back wages.

That total $1 million is less than half of all back wages owed to Blackjewel miners, but attorneys who filed a class action suit against the company said miners have a priority lien on the purchase price. That could allow former Blackjewel employees to make good on their back wages as bankruptcy proceedings continue.

Mosley said he spoke with a Kopper Glo official Thursday, who said the company is working to re-open the mines as quickly as possible. The official did not give an exact timeline.

Electrifying Manitoba: How hydro power 'absolutely revolutionized' the province

Manitoba Electrification History charts arc lights, hydroelectric dams, Winnipeg utilities, transmission lines, rural electrification, and Manitoba Hydro to today's wind, solar, and EV transition across the provincial power grid, driving modernization and reliability.

 

Key Points

Manitoba's power evolution from arc lights to hydro and rural electrification, advancing wind and solar on a modern grid.

✅ 1873 Winnipeg arc light predates Edison and Bell.

✅ 1919 Act built transmission lines, rural electrification.

✅ Hydroelectric dams reshaped lands and affected First Nations.

 

The first electric light in Manitoba was turned on in Winnipeg in 1873, but it was a century ago this year that the switch was flipped on a decision that would bring power to the fingertips of people across the province.

On March 12, 1873, Robert Davis — who owned the Davis House hotel on Main Street, about a block from Portage Avenue — used an electric arc light to illuminate the front of his building, according to A History of Electric Power in Manitoba, published by Manitoba Hydro.

That type of light used an an inert gas in a glass container to create an electric arc between two metal electrodes.

"The lamp in front of the Davis Hotel is quite an institution," a Manitoba Free Press report from the day said. "It looks well and guides the weary traveller to a haven of rest, billiards and hot drinks."

The event took place six years before Thomas Edison's first incandescent lamp was invented and three years before the first complete sentence was spoken over the telephone by Alexander Graham Bell.

"Electrification probably had a bigger influence on the lives of Manitobans than virtually anything else," said Gordon Goldsborough, head researcher with the Manitoba Historical Society.

"It's one of the most significant changes in the lives of Manitobans ever, because basically it transformed so many aspects of their lives. It wasn't just one thing — it touched pretty much every aspect of life."

 

Winnipeg gets its 1st street lamps

In the pioneer days of lighting and street railway transportation in Winnipeg, multiple companies formed in an effort to take advantage of the new utility: Winnipeg Gas Company, Winnipeg General Power Company, Manitoba Electric and Gas Light Company, and The North West Electric Light and Power Company.

In October 1882, the first four street lamps, using electric arc lights, were turned on along Main Street from Broadway to the CPR crossing over the Assiniboine River.

They were installed privately by P.V. Carroll, who came from New York to establish the Manitoba Electric Light & Power Company and try to win a contract for illuminating the rest of the city's streets.

He didn't get it. Newspaper reports from the time noted many outages and other problems and general disappointment in the quality of the light.

Instead, the North West Electric Light and Power Company won that contract and in June 1883 it lit up the streets.

Over the years, other companies would bring power to the city as it became more reliable, including the Winnipeg Electric Street Railway Company (WERCo), which built the streetcar system and sold electric heat, light and power.

But it was the Brandon Electric Light Company that first tapped into a new source of power — hydro. In 1900, a dam was built across the Minnedosa River (now known as the Little Saskatchewan River) in western Manitoba, and the province's first hydroelectric generating station was created.

The first transmission line was also built, connecting the station with Brandon.

By 1906, WERCo had taken over the Winnipeg General Power Company and the Manitoba Electric and Gas Light Company, and changed its name to the Winnipeg Electric Railway Company. Later, it became the Winnipeg Electric Company, or WECo.

It also took a cue from Brandon, building a hydroelectric plant to provide more power. The Pinawa dam site operated until 1951 and is now a provincial park.

The City of Winnipeg Hydroelectric System was also formed in 1906 as a public utility to combat the growing power monopoly held by WECo, and to get cheaper power. The city had been buying its supply from the private company "and the City of Winnipeg didn't quite like that price," said Bruce Owen, spokesman for Manitoba Hydro.

So the city funded and built its own dam and generating station site on the Winnipeg River in Pointe du Bois — about 125 kilometres northeast of Winnipeg — which is still in operation today.

"All of a sudden, not only did we have street lights … businesses had lights, power was supplied to homes, people no longer had to cook on wood stoves or walk around with kerosene lanterns. This city took off," said Owen.

"It helped industry grow in the city of Winnipeg. Within a few short years, a second plant had to be built, at Slave Falls."

 

Lighting up rural Manitoba

While the province's two biggest cities enjoyed the luxury of electricity and the conveniences it brought, the patchwork of power suppliers had also created a jumble of contracts with differing rates and terms, spurring periodic calls for a western Canadian electricity grid to improve coordination.

Meanwhile, most of rural Manitoba remained in the dark.

That began to change in 1919 when the Manitoba government passed the Electric Power Transmission Act, with the aim of supplying rural Manitoba with electrical power. The act enabled the construction of transmission lines to carry electricity from the Winnipeg River generating stations to communities all over southern Manitoba.

It also created the Manitoba Power Commission, predecessor to today's Manitoba Hydro, to purchase power from the City of Winnipeg — and later WECo — to supply to those other communities.

The first transmission line, a 97-kilometre link between Winnipeg and Portage la Prairie, opened in late 1919, and modern interprovincial projects like Manitoba-Saskatchewan power line funding continue that legacy today. The power came from Pointe du Bois to a Winnipeg converter station that still stands at the corner of Stafford Street and Scotland Avenue, then went on to Portage la Prairie.

"That's the remarkable thing that started in 1919," said Goldsborough.

Every year after that, the list of towns connected to the power grid became longer "and gradually, over the early 20th century, the province became electrified," Goldsborough said.

"You'd see these maps that would spider out across the province showing the [lines] that connected each of these communities — a precursor to ideas like macrogrids — to each other, and it was really quite remarkable."

By 1928, 33 towns were connected to the Manitoba Power Commission grid. That rose to 44 by 1930 and 140 by 1939, according to the Manitoba Historical Society.

 

Power on the farm

Still, one group who could greatly use electricity for their operations — farmers — were still using lanterns, steam and coal for light, heat and power.

"The power that came to the [nearest] town didn't extend to them," said Goldsborough.

It was during the Second World War, as manual labour was hard to come by on farms, that the Manitoba Power Commission recognized the gap in its grid.

It met with farmers to explain the benefits electricity could bring and surveyed their interest. When the war ended in 1945, the farm electrification process got underway.

Farmers were taught wiring techniques and about the use of motors for farm equipment, as well as about electric appliances and other devices to ease the burden of domestic life.

"The electrification of the 1940s and '50s absolutely revolutionized rural life," said Goldsborough.

"Farmers had to provide water for all those animals and in a lot of cases [prior to electrification] they would just use a hand pump, or sometimes they'd have a windmill. But these were devices that weren't especially reliable and they weren't high capacity."

Electric motors changed everything, from pumping water to handling grain, while electric heat provided comfort to both people and animals.

"Now you could have heat lamps for your baby chickens. They would lose a lot of chickens normally, because they would simply be too cold," Goldsborough said.

Keeping things warm was important, but so too was refrigeration. In addition to being able to store meat in summer, it was "something to prolong the life of dairy products, eggs, anything," said Manitoba Hydro's Owen.

"It's all the things we take for granted — a flick of a switch to turn the lights on instead of walking around with a lantern, being able to have maybe a bit longer day to do routine work because you have light."

Agriculture was the backbone of the province but it was limited without electricity, said Owen.

Connecting it to the grid "brought it into the modern age and truly kick-started it to make it a viable part of our economy," he said. "And we still see that today."

In 1954, when the farm electrification program ended, Manitoba was the most wired of the western provinces, with 75 per cent of farms and 100,000 customers connected.

The success of the farm electrification program, combined with the post-war boom, brought new challenges, as the existing power generation could not support the new demand.

The three largest players — City Hydro, WECo and the Manitoba Power Commission, along with the provincial government  — created the Manitoba Hydro-Electric Board in 1949 to co-ordinate generation and distribution of power.

More hydroelectric generating stations were built and more reorganizations took place. WECo was absorbed by the board and its assets split into separate companies — Greater Winnipeg Gas and Greater Winnipeg Transit.

Its electricity distribution properties were sold to City Hydro, which became the sole distributor in central Winnipeg. The Manitoba Power Commission became sole distributor of electricity in the suburbs and the rest of Manitoba.

 

Impacts on First Nations

Even as the lives of many people in the province were made easier by the supply of electricity, many others suffered from negative impacts in the rush of progress.

Many First Nations were displaced by hydro dams, which flooded their ancestral lands and destroyed their traditional ways of life.

"And we hear stories about the potential abuses that occurred," said Goldsborough. "So you know, there are there pluses but there are definitely minuses."

In the late 1950s, the Manitoba Power Commission continued to grow and expand its reach, this time moving into the north by buying up private utilities in The Pas and Cranberry Portage.

In 1961, the provincial government merged the commission with the Manitoba Hydro-Electric Board to create Manitoba Hydro.

In 1973, 100 years after the first light went on at that Main Street hotel, the last of the independent power utilities in the province — the Northern Manitoba Power Company Ltd. — was taken over by Hydro.

Winnipeg Hydro, previously called City Hydro, joined the fold in 2002.

Today, Manitoba Hydro operates 15 generating stations and serves 580,262 electric power customers in the province, as well as 281,990 natural gas customers.

 

New era

And now, as happened in 1919, a new era in electricity distribution is emerging as alternative sources of power — wind and solar — grow in popularity, and as communities like Fort Frances explore integrated microgrids for resilience.

"There's a bit of a clean energy shift happening," said Owen, adding use of biomass energy — energy production from plant or animal material — is also expanding.

"And there's a technological change going on and that's the electrification of vehicles. There are only really several hundred [electric vehicles] in Manitoba on the streets right now. But we know at some point, with affordability and reliability, there'll be a switch over and the gas-powered internal combustion engine will start to disappear."

'We're just a little behind here': Manitoba electric vehicle owners call for more charging stations

That means electrical utilities around the world are re-examining their capabilities, as climate change increasingly stresses grids, said Owen.

"It's coming [and we need to know], are we in a position to meet it? What will be the demands on the system on a path to a net-zero grid by 2050 nationwide?" he said.

"It may not come in my lifetime, but it is coming."

Alberta Introduces New Electricity Rules

Alberta Rate of Last Resort streamlines electricity regulations to stabilize the default rate, curb price volatility, and protect rural communities, low-income households, and seniors while preserving competition in the province's energy market.

 

Key Points

Alberta's Rate of Last Resort sets biennial default electricity prices, curbing volatility and protecting customers.

✅ Biennial default rate to limit price spikes

✅ Focus on rural, senior, and low-income customers

✅ Encourages competitive contracts and market stability

 

The Alberta government is overhauling its electricity regulations as part of a market overhaul aimed at reducing spikes in electricity prices for consumers and businesses. The new rules, set to be introduced this spring, are intended to stabilize the default electricity rate paid by many Albertans.


Background on the Rate of Last Resort

Albertans currently have the option to sign up for competitive contracts with electricity providers. These contracts can sometimes offer lower rates than the default electricity rate, officially known as the Regulated Rate Option (RRO). However, these competitive rates can fluctuate significantly. Currently, those unable to secure these contracts or those who are on the default rate are experiencing rising electricity prices and high levels of price volatility.

To address this, the Alberta government is renaming the default rate as the Rate of Last Resort designation (RoLR) under the new framework. This aims to reduce the sense of security that some consumers might associate with the current name, which the government feels is misleading.


Key Changes Under New Regulations

The new regulations, which include proposed market changes that affect pricing, focus on:

  • Price Stabilization: Default electricity rates will be set every two years for each utility provider, providing greater predictability by enabling a consumer price cap and reducing the potential for extreme price swings.
  • Rural and Underserved Communities: The changes are intended to particularly benefit rural Albertans and those on the default rate, including low-income individuals and seniors. These groups often lack access to the competitive rates offered by some providers and have been disproportionately affected by recent price increases.
  • Promoting Economic Stability: The goal is to lower the cost of utilities for all Albertans, leading to overall lower costs of living and doing business. The government anticipates these changes will create a more attractive environment for investment and job creation.


Opposition Views

Critics argue that limiting the flexibility of prices for the default electricity rate could interfere with market dynamics and stifle market competition among providers. Some worry it could ultimately lead to higher prices in the long term. Others advocate directly subsidizing low-income households rather than introducing broad price controls.


Balancing Affordability and the Market

The Alberta government maintains that the proposed changes will strike a balance between ensuring affordable electricity for vulnerable Albertans and preserving a competitive energy market. Provincial officials emphasize that the new regulations should not deter consumers from seeking out competitive rates if they choose to.


The Path Ahead

The new electricity regulations are part of the Alberta government's broader Affordable Utilities Program, alongside electricity policy changes across the province. The legislation is expected to be introduced and debated in the provincial legislature this spring with the potential of coming into effect later in the year. Experts expect these changes will significantly impact the Alberta electricity market and ignite further discussion about how best to manage rising utility costs for consumers and businesses.

South Australia rides renewables boom to become electricity exporter

Australia electricity grid transition is accelerating as renewables, wind, solar, and storage drive decentralised generation, emissions cuts, and NEM trade shifts, with South Australia becoming a net exporter post-Hazelwood closure and rooftop solar surging.

 

Key Points

Australia electricity shift to renewables, distributed generation and storage, cutting emissions, reshaping NEM flows.

✅ South Australia now exports power post-Hazelwood closure

✅ Rooftop solar is the fastest-growing NEM generation source

✅ Gas peaking and storage investments balance variable renewables

 

The politics may not change much, but Australia’s electricity grid is changing before our very eyes – slowly and inevitably becoming more renewable, more decentralised, and in step with Australia's energy transition that is challenging the pre-conceptions of many in the industry.

The latest national emissions audit from The Australia Institute, which includes an update on key electricity trends in the national electricity market, notes some interesting developments over the last three months.

The most surprising of those developments may be the South Australia achievement, which shows that since the closure of the Hazelwood brown coal generator in Victoria in March 2017, and as renewables outpacing brown coal in other markets, South Australia has become a net exporter of electricity, in net annualised terms.

Hugh Saddler, lead author of the study, notes that this is a big change for South Australia, which in 1999 and 2000, when it had only gas and local coal, used to import 30% of its electricity demand.

#google#

The fact that wholesale prices in South Australia were higher in other states – then, as they are now – has nothing to with wind and solar, but the fact that it has no low-cost conventional source and a peaky demand profile (then and now).

“The difference today is that the state is now taking advantage of its abundant resources of wind and solar radiation, and the new technologies which have made them the lowest cost sources of new generation, to supply much of its electricity requirements,” Saddler writes.

Other things to note about the flows between states is that Victoria was about equal on imports and exports with its three neighbouring states, despite the closure of Hazelwood. NSW continues to import around 10% of its needs from cheaper providers in Queensland.

Gas-fired generation had increased in the last year or two in South Australia as a result of the Northern closure, but is still below the levels of a decade ago.

But because it is expensive, this is likely to spur more investment in storage.

As for rooftop solar, Saddler notes that the share of residential solar in the grid is still relatively small but, despite excess solar risks flagged by distributors, it is the most steadily growing generation source in the NEM.

That line is expected to grow steadily. By 2040, or perhaps 2050, the share of distributed generation, which includes rooftop solar, battery storage and demand management, is expected to reach nearly half of all Australia’s grid demand.

Saddler, says, however, that the increase in large-scale solar over the last few months is a significant milestone in Australia’s transition towards clean electricity generation, mirroring trends in India's on-grid solar development seen in recent years. (See very top graph).

“Firstly, they are a concrete demonstration that the construction cost advantage, which wind enjoyed over solar until a year or two ago, is gone.

“From now on we can expect new capacity to be a mix of both technologies. Indeed, the Clean Energy Regulator states that it expects solar to account for half of all (new renewable) capacity by 2020, and the US is moving toward 30% from wind and solar as well.”

Ameren, Safe Electricity urge safety near downed lines

Downed Power Line Vehicle Safety: Follow stay-in-the-car protocol, call 911, avoid live wires and utility poles, and use the bunny hop to escape only for fire. Electrical hazards demand emergency response caution.

 

Key Points

Stay in the car, call 911, and use a bunny hop escape only if fire threatens during downed power line incidents.

✅ Stay in vehicle; tell bystanders to keep back and call 911.

✅ Exit only for fire; jump clear and bunny hop away.

✅ Treat all downed lines as live; avoid paths to ground.

 

Ameren Illinois and Safe Electricity are urging the public to stay in their cars and call 911 in the event of an accident involving a power pole that brings down power lines on or around the car.

In a media simulation Tuesday at the Ameren facility on West Lafayette Avenue, Ameren Illinois employees demonstrated the proper way to react if a power line has fallen on or around a vehicle, as some utilities consider on-site staffing measures during outbreaks. Although the situation might seem rare, Illinois motorists alone hit 3,000 power poles each year, said Krista Lisser, communications director for Safe Energy.

“We want to get the word out that, if you hit a utility pole and a live wire falls on your vehicle, stay in your car,” Lisser said. “Our first reaction is we panic and think we need to get out, a sign of the electrical knowledge gap many people have. That’s not the case, you need to stay in because, when that live wire comes down, electricity is all around you. You may not see it, it may not arc, it may not flash, you may not know if there’s electricity there.”

Should someoneinvolved in such an accident see a good Samaritan attempting to help, he should try to tell the would-be rescuer to stay back to prevent injury to the Samaritan, Ameren Illinois Communications Executive Brian Bretsch said.

“We have seen instances where someone comes up and wants to help you,” Bretsch said. “You want to yell, ‘Please stay away from the vehicle. Everyone is OK. Please stay away.’ You’ll see … instances every now and then where the Samaritan will come up, create that path to ground and get injured, and there are also climbers seeking social media glory who put themselves at risk.”

The only instance in which one should exit a car in the vicinity of a downed wire is if the vehicle is on fire and there is no choice but to exit. In that situation, those in the car should “bunny hop” out of the car by jumping from the car without touching the car and the ground at the same time, Bretsch and Lisser said.

After the initial jump, those escaping the vehicle should continue jumping with both feet together and hands tucked in and away from danger until they are safely clear of the downed wire.

It’s important for everyone to be informed, because an encounter with a live wire could easily result in serious injury, as in the Hydro One worker injury case, or death, Lisser said.

“They’re so close to our roads, especially in our rural communities, that it’s quite a common occurrence,” Lisser said. “Just stay away from (downed lines), especially after storms and amid grid oversight warnings that highlight reliability risks … Always treat a downed line as a live wire.
