The word "challenging" comes up often when people in the electricity business are asked whether Ontario's polluting coal-fired generating stations can be shut down in 2007.

Another favourite: "Tough."

"Very tight deadlines" is a common refrain.

And that leads to the most crucial word of all: "Cautious."

As in, few companies are yet rushing in to build new, cleaner plants to make up for the power produced by the smoke-belching behemoths in Etobicoke, Nanticoke, Sarnia, Thunder Bay and Atikokan.

Nobody doubts the province would be better off without the noxious emissions that spew from the plants, operated by Ontario Power Generation.

They contribute in a big way to air pollution that the Ontario Medical Association says leads to 2,000 premature deaths and thousands of hospital admissions each year, and adds $1.2 billion a year in health costs and lost productivity.

The Liberals scored with voters when they promised in last year's election campaign to douse the massive coal fires within four years.

But those plants combined can generate more than 7,550 megawatts of power —one-quarter of Ontario's capacity and one-third of its normal peak demand.

That production must be replaced, by reducing consumption or building new plants.

Premier Dalton McGuinty's government insists it has a plan. Energy Minister Dwight Duncan has unveiled parts of it over the past nine months. They're short of what's needed, but Duncan says more measures will be announced this fall.

"This government is moving heaven and earth to achieve its goal in the timeline set out. We believe we'll be able to achieve it."

Power experts say that, at best, keeping the promise will be a Herculean task. Some angrily argue that the way the province is going about it is too flawed and biased to succeed.

It doesn't help that last week, OPG revealed problems with fuel channels — which contain uranium bundles in the reactor — at its Pickering B nuclear station. As a result, the reactors will need more maintenance and be out of service more frequently than planned.

"It's a challenging deadline, but probably not beyond the scope of human ingenuity," says David Butters, president of the Association of Power Producers of Ontario, an industry lobby group.

The province won't suffer power shortages.

"One thing I can say about the coal phase-out is we're not going to let the lights go out," Dave Goulding, chief executive of the Independent Electricity Market Operator, or IMO, which runs Ontario's power system, told the Star's John Spears this month.

At issue are when Ontario's air will get cleaner and whether the government must break yet another election promise.

So far, Duncan has:

Authorized OPG to repair and restart an idle reactor at the Pickering A nuclear station. That will increase the province's generating capacity by 515 megawatts, or enough power to supply 350,000 average homes. The utility says the work can be completed in 15 months at a cost of $900 million.

It's a decent amount of power. But critics say pouring more money into Pickering is a major mistake, given the high cost of nuclear power, OPG's abysmal record with previous repairs and the costly and dangerous problems of dealing with used radioactive fuel.

The Pickering announcement is "the biggest misstep of the McGuinty government," says Jack Gibbons, head of the Ontario Clean Air Alliance, an environmental lobby group.

Approved construction of another huge water pipe to boost the capacity of the Niagara Falls hydroelectric station by 230 megawatts. That's a straightforward, non-polluting project with virtually no critics. Unfortunately, it won't be finished until 2009.

Requested proposals from private companies to generate 300 megawatts using wind, solar or other renewable energy sources. Duncan has been swamped with responses; 90 projects totalling about 4,400 megawatts. Industry observers figure about half are viable. Those that win the competition are required to have their projects up and running by the end of 2007.

Requested proposals for another 2,500 megawatts, either through building new generating stations or curbing industrial demand. This seems very helpful. But the deadline for completing new projects isn't until Dec. 31, 2009. And it's not certain how many companies will participate.

If all four measures pan out, the government can count on adding at most 3,315 megawatts of capacity by the end of 2007 — the promised deadline for shutting the coal-fired plants. That would leave it 4,235 megawatts short.

Add two recently opened gas-fuelled plants in Windsor and Sarnia and the deficit drops to about 3,000 megawatts.

The situation could be improved if homeowners use less power. The government aims for a five per cent cut by 2007. That could, very roughly speaking, cut the amount of capacity Ontario requires by about 1,300 megawatts, Duncan says.

Then, the province would be about 1,700 megawatts short of its target.

But critics say that, so far, the conservation plan is a dim bulb.

Last October, Duncan announced $225 million for Toronto Hydro and other municipal utilities to promote reduced consumption.

But the utilities' profits go down if their customers buy less electricity. Consequently, they haven't spent much of the money. What they have spent has mainly gone toward what Gibbons calls "feel good" TV and newspaper ads with little impact.

The government also plans to spend $400 million to install "smart meters" — which give consumers a price break if they use electricity at off-peak times — in 800,000 Ontario homes by the end of 2007 and all of them by 2010. The meters will cost homeowners $1 to $3 a month.

But there's no clear evidence how much electricity the meters will save. And much of any effect they'll have won't come until well after 2007.

The biggest part of the government's plan is construction of new generating stations, likely fuelled by natural gas. They are far more efficient than coal-fired plants and emit a small fraction as much pollution.

Under the plan, companies must bid for the right to build projects. Those that offer the lowest price and meet other criteria will be picked, until the goal of 2,500 megawatts is achieved.

The idea, at its simplest, is that project owners will be contracted to produce a certain amount of power — much less than their plants' full capacity because demand fluctuates and is usually below its peak — which they will sell to the provincial system at the price they bid. If the system buys more than the contracted amount from a project, its owner repays any excess revenue. If it buys less, the owner gets reimbursed for the lost income.

It's called "revenue assurance," and it sounds like a good deal for plant operators.

Building enough new plants by the end of 2007 is theoretically possible: Mexico has constructed 8,800 megawatts of capacity since 2001. Whether it will happen in Ontario is another matter.

The IMO has a long list of potential gas projects, totalling about 3,100 megawatts of capacity. It includes every company that agreed to pay for a very preliminary assessment of how it would fit into Ontario's transmission system. Some projects won't go ahead, so while the list is impressive, it's not necessarily meaningful.

The IMO has just begun revising the list to include only the most likely players. Final proposals for new plants must be submitted by Nov. 22. Winners are to be announced Feb. 1, 2005.

One solid prospect appears to be the Portlands Energy Centre, a 550-megawatt plant being developed on Toronto's eastern waterfront by OPG and TransCanada PipeLines Ltd. It's getting special treatment because Toronto needs a new generating station.

Sithe Canadian Holdings, Inc. has proposed projects — about 800 megawatts each — in Brampton and south Mississauga. Because of their location, those, too, get a break in the bidding.

Other potential bidders hedge their bets.

"We're looking very closely at Ontario" but "we have no firm project," says Susan Dowse, of California-based Calpine Corp., which runs a small plant in Whitby. The company has concerns about the method of selecting projects, she says. "We think there's room to optimize it."

"We're considering participating," says John Jenkins of Calgary-based Atco Power, which last month, in partnership with OPG, opened a 580-megawatt gas-fuelled plant in Windsor. "It's a complex situation...we'll have to see.

"We'd like to participate but we're very cautious."

If Atco were to propose another plant, Jenkins says: "2007 will be a very tight schedule."

Another Calgary company, TransAlta Corp., recently began production at a $500 million, 575-megawatt gas-fuelled plant in Sarnia. When construction began, under the previous Conservative government, it appeared Ontario would have a deregulated electricity market, says spokesperson Tim Richter. Because that's no longer the case, the plant is running at only 25 per cent of its capacity, and losing money.

TransAlta won't participate in the first round of bidding, Richter says. Before doing anything else, it must get things sorted out at Sarnia: "We want to ensure our investment in Ontario is protected."

Companies are being cautious for several reasons.

They're worried about the supply and cost of natural gas.

Opinions are mixed on whether Canada can continue to produce enough of the increasingly popular fuel. But as the Star's Spears has reported, one of Canada's experts on gas supply, David Hughes of the Geological Survey of Canada, warns of an energy squeeze in Ontario and suggests closing the coal-burning plants would create unprecedented pressure on gas supplies.

Some in the industry dislike the selection process.

It's long and extremely complicated: It doesn't always take into account how projects will link to the electricity transmission grid. Many fear the rules of Ontario's energy market, radically altered several times since 1995, will be transformed again.

Duncan advises critics to be patient. "We're moving as fast as we can."

The measures he might announce this fall include restarting two idle reactors at the Bruce nuclear station, developing smaller hydroelectric projects, pushing for more renewable and gas-fuelled generating stations.

He's considering moves to increase conservation. "The folks that advocate we need regulatory changes are right. We're looking for the best way to do it."

And he has a big card up his sleeve. The province could tell OPG to convert some or all of the coal-fired plants to natural gas. It would be expensive. The two biggest plants are a long distance from adequate gas supplies. And converted plants are only about half as efficient as new designs.

OPG isn't spending "a lot of time or effort" on plans for converting the plants, says spokesperson John Earle. "We will continue to operate the plants as currently designed. If we're directed by our shareholder (the government) to change the operation, we will."

But that option "is part of the main mix," Duncan says.

It likely must be done. On top of replacing the coal-fired megawatts, the province will require thousands more by 2020 as nuclear plants and other sources reach the end of their operating lives.

"We've got a lot of work to do," Duncan says. "Nothing is easy. There are no simple answers."

No one is disagreeing with that.

Chinese-built electricity poles plant inaugurated in South Sudan

Juba Power Distribution Expansion accelerates grid rehabilitation in South Sudan, adding concrete poles, medium and low voltage networks, and LED street lighting, funded by AfDB and executed by Power China for reliable, affordable electricity.

 

Key Points

A project to upgrade Juba's grid with concrete poles, MV-LV networks, and LED lighting for reliable, affordable power.

✅ 13,350 concrete poles produced locally for network rollout

✅ Medium and low voltage network rehabilitation and expansion

✅ LED street lighting and customer care improvements funded by AfDB

 

The South Sudan government has launched a factory producing concrete poles that will facilitate an ambitious project done by a Chinese company to rehabilitate and expand the Power Distribution System in Juba, its capital.

The Minister of Dams and Electricity, Dhieu Mathok, said that the factory, rented by Power China, will produce some 13,350 poles for the electricity distribution in the capital and other states.

"The main objective of this project is to increase the supply capacity and reliability of the power distribution system in Juba. Access to the grid will replace the use of generators by the population, allow supply of energy at more affordable price and, hence contribute toward economic growth and poverty eradication in South Sudan," Mathok said during the inauguration of the plant along the Yei road in Juba.

#google#

He disclosed that it will help solve the problem associated with non-availability of concrete poles for the project and to mitigate the risk of importing poles from other countries.

"This factory will create positive impact on the construction of the national grid in South Sudan. It is owned by South Sudanese business people but currently it has been taken over by Power China for a brief period of one year," he said.

South Sudan is largely generator driven economy with continued electricity blackout, and across the continent initiatives like Cape Town's municipal power build-out illustrate alternative approaches, in the wake of the collapse of the generator power plant operated by the South Sudan Electricity Corporation (SSEC) in 2013.

Wang Cun, an official with Power China said they got the contract to build the electricity project in June 2016 and that they will continue to support South Sudanese staff with skills and knowledge, drawing on advances such as PEM green hydrogen R&D that point to future low-carbon options, and also work with the government on several major power projects.

"We have achieved much from these projects and we also suffered much from the instability and continuous conflicts all these years, but we confirm and believe the year of 2018 will be a year of peace and development in South Sudan," Wang said, adding that the company has been operating in South Sudan since 2009.

He disclosed that Power China has conducted several projects before South Sudan won independence from Sudan in 2011 such as the peace road project from Renk to Malakal, Maridi water plant and Malakal municipal road projects.

Wang said they will immediately reorganize all necessary resources to increase post-production capacity and immediately shall commence the erection of these poles to all corners of Juba city and start the distribution.

"We shall do as we did before to recruit more local technicians, engineers and laborers during the construction period, so that they are there in place for similar projects in the near future. We shall make more efforts to improve these local staffs' working environment and to realize sustainable development of Power China and Sino-hydro in South Sudan," said Wang.

Power China has been committing itself in the economic development of South Sudan and has signed eight commercial contracts with the government of South Sudan since independence like the Juba-hydro power project and the Tharjiath thermal power plant project, while in China projects such as the Lawa hydropower station demonstrate ongoing hydropower expertise that can inform regional work.

Liu Xiaodong, the Charge d'Affaires at the Chinese embassy in South Sudan, said Power China has been working very hard in the engineering and procurement in the earlier stage of the project, and as China expands energy ties such as nuclear cooperation with Cambodia that demonstrate broader engagement, also thanked the South Sudan government and the African Development Bank for their strong support.

Liu added upon completion Juba will have an upgraded power distribution system with 2,250 lighting points along the main roads in the capital and lamps will be LED ones.

The project falls under the Juba Power Distribution System Rehabilitation and Expansion Project, which was funded by the African Development Bank (AfDB) and has undertaken an AfDB review of a Senegal power plant to inform regional energy decisions.

It comprises of five different lots like Rehabilitation of Diesel plant substation, Rehabilitation and Expansion of medium voltage network, low voltage network, and Rehabilitation and Expansion of street lighting and improvement of customer care.

California's future with income-based flat-fee utility bills is getting closer

California Income-Based Utility Fees would overhaul electricity bills as CPUC weighs fixed charges tied to income, grid maintenance costs, AB 205 changes, and per-kilowatt-hour rates, shifting from pure usage pricing to hybrid utility rate design.

 

Key Points

Income-based utility fees are fixed monthly charges tied to earnings, alongside per-kWh rates, to help fund grid costs.

✅ CPUC considers fixed charges by income under AB 205

✅ Separates grid costs from per-kWh energy charges

✅ Could shift rooftop solar and EV charging economics

 

Electricity bills in California are likely to change dramatically in 2026, with major changes under discussion statewide.

The California Public Utilities Commission (CPUC) is in the midst of an unprecedented overhaul of the way most of the state’s residents pay for electricity, as it considers revamping electricity rates to meet grid and climate goals.

Utility bills currently rely on a use-more pay-more system, where bills are directly tied to how much electricity a resident consumes, a setup that helps explain why prices are soaring for many households.

California lawmakers are asking regulators to take a different approach, and some are preparing to crack down on utility spending as oversight intensifies. Some of the bill will pay for the kilowatt hours a customer uses and a monthly fixed fee will help pay for expenses to maintain the electric grid: the poles, the substations, the batteries, and the wires that bring power to people’s homes.

The adjustments to the state’s public utility code, section 739.9, came about because of changes written into a sweeping energy bill passed last summer, AB 205, though some lawmakers now aim to overturn income-based charges in subsequent measures.

A stroke of a pen, a legislative vote, and the governor’s signature created a move toward unprecedented income-based fixed charges across the state.

“This was put in at the last minute,” said Ahmad Faruqui, a California economist with a long professional background in utility rates. “Nobody even knew it was happening. It was not debated on the floor of the assembly where it was supposedly passed. Of course, the governor signed it.”

Faruqui wonders who was responsible for legislation that was added to the energy bill during the budget writing process. That process is not transparent.

“It’s a very small clause in a very long bill, which is mostly about other issues,” Faruqui said.

But that small adjustment could have a massive impact on California residents, because it links the size of a monthly flat fee for utility service to a resident’s income. Earn more money and pay a higher flat fee.

That fee must be paid even before customers are charged for how much power they draw.

Regulators interpreted legislative change as a mandate, but Faruqui is not sold.

“They said the commission may consider or should consider,” Faruqui said. “They didn’t mandate it. It’s worth re-reading it.”

In fact, the legislative language says the commission “may” adopt income-based flat fees for utilities. It does not say the commission “should” adopt them.

Nevertheless, the CPUC has already requested and received nine proposals for how a flat fee should be implemented, as regulators face calls for action amid soaring electricity bills.

The suggestions came from consumer groups, environmentalists, the solar industry and utilities.

India's electricity demand falls at the fastest pace in at least 12 years

India Industrial Output Slowdown deepens as power demand slumps, IIP contracts, and electricity, manufacturing, and mining weaken; capital goods plunge while RBI rate cuts struggle to lift GDP growth, infrastructure, and fuel demand.

 

Key Points

A downturn where IIP contracts as power demand, manufacturing, mining, and capital goods fall despite RBI rate cuts.

✅ IIP fell 4.3% in Sep, worst since Feb 2013.

✅ Power demand dropped for a third month, signaling weak industry.

✅ Capital goods output plunged 20.7%, highlighting weak investment.

 

India's power demand fell at the fastest pace in at least 12 years in October, signalling a continued decline in the industrial output, mirroring how China's power demand dropped when plants were shuttered, according to government data. Electricity has about 8% weighting in the country's index for industrial production.

India needs electricity to fuel its expanding economy and has at times rationed coal supplies when demand surged, but a third decline in power consumption in as many months points to tapering industrial activity in a nation that aims to become a $5 trillion economy by 2024.

India's industrial output fell at the fastest pace in over six years in September, adding to a series of weak indicators that suggests that the country’s economic slowdown is deep-rooted and interest rate cuts alone may not be enough to revive growth.

Annual industrial output contracted 4.3% in September, government data showed on Monday. It was the worst performance since a 4.4% contraction in February 2013, according to Refinitiv data.

Analysts polled by Reuters had forecast industrial output to fall 2% for the month.

“A contraction of industrial production by 4.3% in September is serious and indicative of a significant slowdown as both investment and consumption demand have collapsed,” said Rupa Rege Nitsure, chief economist of L&T Finance Holdings.

The industrial output figure is the latest in a series of worrying economic data in Asia's third largest economy, which is also the world's third-largest electricity producer as well.

Economists say that weak series of data could mean economic growth for July-September period will remain near April-June quarter levels of 5%, which was a six-year low, and some analysts argue for rewiring India's electricity to bolster productivity. The Indian government is likely to release April-September economic growth figures by the end of this month.

Subdued inflation and an economic slowdown have prompted the Reserve Bank of India (RBI) to cut interest rates by a total of 135 basis points this year, while coal and electricity shortages eased in recent months.

“These are tough times for the RBI, as it cannot do much about it but there will be pressures on it to act ...Blunt tools like monetary policy may not be effective anymore,” Nitsure said.

Data showed in September mining sector fell 8.5%, while manufacturing and electricity fell 3.9% and 2.6% respectively, even as imported coal volumes rose during April-October. Capital goods output during the month fell 20.7%, indicating sluggish demand.

“IIP (Index of Industrial Production) growth in October 2019 is also likely to be in negative territory and only since November 2019 one can expect mild IIP expansion, said Devendra Kumar Pant, Chief Economist and Senior Director, Public Finance, India Ratings & Research (Fitch Group).

Infrastructure output, which comprises eight main sectors, in September showed a contraction of 5.2%, the worst in 14 years, even as global daily electricity demand fell about 15% during pandemic lockdowns.

India's fuel demand fell to its lowest in more than two years in September, with consumption of diesel to its lowest levels since January 2017. Diesel and gasoline together make up over 7.4% of the IIP weightage.

In 2019/20 India's fuel demand — also seen as an indicator of economic and industrial activity — is expected to post the slowest growth in about six years.

Some old dams are being given a new power: generating clean electricity

Hydroelectric retrofits for unpowered dams leverage turbines to add renewable capacity, bolster grid reliability, and enable low-impact energy storage, supporting U.S. and Canada decarbonization goals with lower costs, minimal habitat disruption, and climate resilience.

 

Key Points

They add turbines to existing dams to make clean power, stabilize the grid, and offer low-impact storage at lower cost.

✅ Lower capex than new dams; minimal habitat disruption

✅ Adds firming and storage to support wind and solar

✅ New low-head turbines unlock more retrofit sites

 

As countries race to get their power grids off fossil fuels to fight climate change, there's a big push in the U.S. to upgrade dams built for purposes such as water management or navigation with a feature they never had before — hydroelectric turbines. 

And the strategy is being used in parts of Canada, too, with growing interest in hydropower from Canada supplying New York and New England.

The U.S. Energy Information Administration says only three per cent of 90,000 U.S. dams currently generate electricity. A 2012 report from the U.S. Department of Energy found that those dams have 12,000 megawatts (MW) of potential hydroelectric generation capacity. (According to the National Hydropower Association, 1 MW can power 750 to 1,000 homes. That means 12,000 MW should be able to power more than nine million homes.)

As of May 2019, there were projects planned to convert 32 unpowered dams to add 330 MW to the grid over the next several years.

One that was recently completed was the Red Rock Hydroelectric Project, a 60-year-old flood control dam on the Des Moines River in Iowa that was retrofitted in 2014 to generate 36.4 MW at normal reservoir levels, and up to 55 MW at high reservoir levels and flows. It started feeding power to the grid this spring, and is expected to generate enough annually to supply power to 18,000 homes.

It's an approach that advocates say can convert more of the grid from fossil fuels to clean energy, often with a lower cost and environmental impact than building new dams.

Hydroelectric facilities can also be used for energy storage, complementing intermittent clean energy sources such as wind and solar with pumped storage to help maintain a more reliable, resilient grid.

The Nature Conservancy and the World Wildlife Fund are two environmental groups that oppose new hydro dams because they can block fish migration, harm water quality, damage surrounding ecosystems and release methane and CO2, and in some regions, Western Canada drought has reduced hydropower output as reservoirs run low. But they say adding turbines to non-powered dams can be part of a shift toward low-impact hydro projects that can support expansion of solar and wind power.

Paul Norris, president of the Ontario Waterpower Association, said there's typically widespread community support for such projects in his province amid ongoing debate over whether Ontario is embracing clean power in its future plans. "Any time that you can better use existing assets, I think that's a good thing."

New turbine technology means water doesn't need to fall from as great a height to generate power, providing opportunities at sites that weren't commercially viable in the past, Norris said, with recent investments such as new turbines in Manitoba showing what is possible.

In Ontario, about 1,000 unpowered dams are owned by various levels of government. "With the appropriate policy framework, many of these assets have the potential to be retrofitted for small hydro," Norris wrote in a letter to Ontario's Independent Electricity System Operator this year as part of a discussion on small-scale local energy generation resources.

He told CBC that several such projects are already in operation, such as a 950 kW retrofit of the McLeod Dam at the Moira River in Belleville, Ont., in 2008. 

Four hydro stations were going to be added during dam refurbishment on the Trent-Severn Waterway, but they were among 758 renewable energy projects cancelled by Premier Doug Ford's government after his election in 2018, a move examined in an analysis of Ontario's dirtier electricity outlook and its implications.

Patrick Bateman, senior vice-president of Waterpower Canada, said such dam retrofit projects are uncommon in most provinces. "I don't see it being a large part of the future electricity generation capacity."

He said there has been less movement on retrofitting unpowered dams in Canada compared to the U.S., because:

There are a lot more opportunities in Canada to refurbish large, existing hydro-generating stations to boost capacity on a bigger scale.

There's less growth in demand for clean energy, because more of Canada's grid is already non-carbon-emitting (80 per cent) compared to the U.S. (40 per cent).

Even so, Norris thinks Canadians should be looking at all opportunities and options when it comes to transitioning the grid away from fossil fuels, including retrofitting non-powered dams, especially as a recent report highlights Canada's looming power problem over the coming decades.

"If we're going to be serious about addressing the inevitable challenges associated with climate change targets and net zero, it really is an all-of-the-above approach."

New Electricity Auctions Will Drive Down Costs for Ontario's Consumers

IESO Capacity Auctions will competitively procure resources for Ontario electricity needs, boosting reliability and resource adequacy through market-based bidding, enabling demand response, energy storage, and flexible supply to meet changing load and regional grid conditions.

 

Key Points

A competitive, technology-neutral auction buys capacity at lowest cost to keep Ontario's grid reliable and flexible.

✅ Market-based procurement reduces system costs.

✅ Enables demand response, storage, and hybrid resources.

✅ Increases flexibility and regional reliability in Ontario.

 

The Independent Electricity System Operator (IESO) is introducing changes to Ontario's electricity system that will help save Ontarians about $3.4 billion over a 10-year period. The changes include holding annual capacity auctions to acquire electricity resources at lowest cost that can be called upon when and where they are needed to meet Ontario electricity needs. 

Today's announcement marks the release of a high level design for future auctions, with changes for electricity consumers expected as the first is set to be held in late 2022.

"These auctions will specify how much electricity we need, and introduce a competitive process to determine who can meet that need. It's a competition among all eligible resources, and it's the Ontario consumer, including industrial electricity ratepayers, who benefits through lower costs and a more flexible system better able to respond to changing demand and supply conditions," says IESO President and CEO Peter Gregg.

In the past decade, electricity supply was typically acquired through very prescriptive means with defined targets for specific types of resources such as wind and solar, and secured through 20-year contracts.  While these long-term commitments helped Ontario transform its generation fleet over the last decade, electricity cost allocation also played a role, but longer term contracts provide limited flexibility in dealing with unexpected changes in the power system. 

"Imagine signing a 20-year contract for your cable TV service. In five years' time, electricity rates could be lower, new competitors may have entered the market, or entirely new and innovative platforms and services like Netflix may have emerged. You miss out on opportunities for improvement by being locked-in," says Gregg.

Provincial electricity demand has traditionally fluctuated over time due to factors like economic growth, conservation and the introduction of generating resources on local distribution systems, with occasional issues such as phantom demand affecting customers' costs as well. Technological changes are adding another layer of uncertainty to future demand as electric vehicles, energy storage and low-cost solar panels become more common.

"Our planners do their best to forecast electricity demand, but the truth is there's no such thing as certainty in electricity planning. That's why flexibility is so important. We don't want Ontarians to have to pay more on the typical Ontario electricity bill for electricity resources than are needed to ensure a reliable power system that can continue to meet Ontario's needs," says IESO Vice President and COO Leonard Kula.
