Seasonal power rates could cause consumer backlash

Renewables Beat Brown Coal in Australia, as solar and wind surged to nearly 10,000 GWh, stabilizing the grid with battery storage during peak demand, after Hazelwood's closure, Green Energy Markets reported.

Key Points

It describes a 2017-18 summer when solar, wind, and storage generated more electricity than brown coal in Australia.

✅ Solar and wind hit nearly 10,000 GWh in summer 2017-18

✅ Brown coal fell to about 9,100 GWh after Hazelwood closure

✅ Batteries stabilized peak demand; Tesla responded in milliseconds

Renewable energy generated more electricity than brown coal during Australia’s summer for the first time in 2017-18, according to a new report by Green Energy Markets.

Continued growth in solar, as part of Australia's energy transition, pushed renewable generation in Australia to just under 10,000 gigawatt hours between December 2017 and February 2018. With the Hazelwood plant knocked out of the system last year, brown coal’s output in the same period was just over 9,100 GWh.

Renewables produced 40% more than gas over the period, and was exceeded only by black coal, reflecting trends seen in U.S. renewables surpassing coal in 2022.

The report, commissioned by GetUp, found renewables were generating particularly large amounts of electricity when it was most needed, producing 32% more than brown coal during summer between 11am and 7pm, when demand peaks.

Coal in decline: an energy industry on life support

Solar in particular was working to support the system, on average producing more than Hazelwood was capable of producing between 9am and 5pm.

A further 5,000 megawatts of large-scale renewables projects was under construction in February, supporting 17,445 jobs, while renewables became the second-most prevalent U.S. electricity source in 2020.

GetUp’s campaign director, Miriam Lyons, said the latest renewable energy index showed renewables were keeping the lights on while coal became increasingly unreliable, a trend echoed as renewables surpassed coal in the U.S. in recent years.

“Over summer renewables kept houses cool and lights on during peak demand times when people needed electricity most,” Lyons said. “Meanwhile dirty old coal plants are becoming increasingly unreliable in the heat.

“These ageing clunkers failed 36 times over summer.

“Clean energy rescued people from blackouts this summer. When the clapped-out Loy Yang coal plant tripped, South Australia’s giant Tesla battery reacted in milliseconds to keep the power on.

“It’s clear that a smart electricity grid based on a combination of renewable energy and storage is the best way to deliver clean, affordable energy for all Australians.”

Ontario Hydro Rate Cuts address soaring electricity prices, lowering hydro bills via refinancing, FAO-reviewed costs, and long-term infrastructure investment, balancing ratepayer relief with a projected $21 billion net expense over 30 years.

Key Points

Ontario electricity bill relief spreading infrastructure and green energy costs over 30 years via refinancing.

✅ 25% average bill cut; $156 to $123 per month

✅ FAO projects $21B net cost over 30 years

✅ Costs shifted to long-term debt, infrastructure, green energy

Premier Kathleen Wynne is making no apologies for the Liberals’ 25 per cent hydro rate cuts, legislation to lower electricity rates that a legislative watchdog warns will cost at least $21 billion over three decades.

In the wake of Financial Accountability Officer Stephen LeClair’s report on the “Fair Hydro Plan,” Wynne emphasized that Ontario electricity consumers demanded and deserved relief.

“You all read the newspaper, you listen to the radio and you watch television — you know the problems that families are having around the province paying for their electricity costs,” the premier told reporters Thursday in Timmins.

That’s why the government moved forward with a rate cut, with recent Hydro One reconnections underscoring the stakes, that will see the average household’s monthly hydro bill drop from $156 to $123 once it fully takes effect next month.

In a 15-page report released Wednesday, the financial accountability officer estimated the initiative would cost the province $45 billion over the next 29 years amid a cabinet warning on prices that electricity costs could soar, while saving ratepayers $24 billion for a next expense of $21 billion.

Both the Progressive Conservatives and the New Democrats oppose the Liberal rate cut, arguing that a deal with Quebec would not lower hydro bills.

But Wynne said the government has in effect renegotiated a mortgage so it will bankroll hydro infrastructure improvements over a longer time period, though some have urged the next government to scrap the Fair Hydro Plan and review options, in order to give customers a break now.

“We’re talking about a 30-year window here. It took at least 30 years, probably 40 years, to let the electricity system degrade to the stage that it had in 2003,” she said, noting “we were having blackouts and brownouts around the province” before her party took office that year.

“There were thousands of kilometres of line that needed to be rebuilt . . . that work hadn’t been done over those generations, so electricity costs were low over that period of time but the work wasn’t being done.”

When her predecessor Dalton McGuinty came to power in 2003, Wynne said Queen’s Park began spending billions on infrastructure improvements, including expensive subsidies for green energy, such as wind turbines and solar panels.

“There’s a lot of work that has been done since then. Literally thousands of kilometres of line have been rebuilt. The coal-fired plants have been shut down. The air is cleaner. There’s less pollution in the air. The system is reliable and renewable,” she said.

“So there’s a cost associated with that and what was happening was that was work that had to be done — and all of those costs were on the shoulders of people today.”

Wynne noted “this electricity grid is an asset that is going to be used for generations to come.”

“My grandchildren are going to benefit from this asset, so I think it’s fair that we spread the cost of that over that 30-year period,” she said.

“That’s how we made this decision.”

Renewable Energy Market Reform aligns solar and wind with modern grid pricing, tackling intermittency via batteries and demand response, stabilizing wholesale power prices, and enabling capacity markets to finance flexible supply for deep decarbonization.

Key Points

A market overhaul that integrates variable renewables, funds flexibility, and stabilizes grids as solar and wind grow.

✅ Dynamic pricing rewards flexibility and demand response

✅ Capacity markets finance reliability during intermittency

✅ Smart grids, storage, HV lines balance variable supply

ALMOST 150 years after photovoltaic cells and wind turbines were invented, they still generate only 7% of the world’s electricity. Yet something remarkable is happening. From being peripheral to the energy system just over a decade ago, they are now growing faster than any other energy source and their falling costs are making them competitive with fossil fuels. BP, an oil firm, expects renewables to account for half of the growth in global energy supply over the next 20 years. It is no longer far-fetched to think that the world is entering an era of clean, unlimited and cheap, abundant electricity for all. About time, too. 

There is a $20trn hitch, though. To get from here to there requires huge amounts of investment over the next few decades, to replace old smog-belching power plants and to upgrade the pylons and wires that bring electricity to consumers. Normally investors like putting their money into electricity because it offers reliable returns. Yet green energy has a dirty secret. The more it is deployed, the more it lowers the price of power from any source. That makes it hard to manage the transition to a carbon-free future, during which many generating technologies, clean and dirty, need to remain profitable if the lights are to stay on. Unless the market is fixed, subsidies to the industry will only grow.

Policymakers are already seeing this inconvenient truth as a reason to put the brakes on renewable energy. In parts of Europe and China, investment in renewables is slowing as subsidies are cut back, even as Europe’s electricity demand continues to rise. However, the solution is not less wind and solar. It is to rethink how the world prices clean energy in order to make better use of it.

Shock to the system

At its heart, the problem is that government-supported renewable energy has been imposed on a market designed in a different era. For much of the 20th century, electricity was made and moved by vertically integrated, state-controlled monopolies. From the 1980s onwards, many of these were broken up, privatised and liberalised, so that market forces could determine where best to invest. Today only about 6% of electricity users get their power from monopolies. Yet everywhere the pressure to decarbonise power supply has brought the state creeping back into markets. This is disruptive for three reasons. The first is the subsidy system itself. The other two are inherent to the nature of wind and solar: their intermittency and their very low running costs. All three help explain why power prices are low and public subsidies are addictive.

First, the splurge of public subsidy, of about $800bn since 2008, has distorted the market. It came about for noble reasons—to counter climate change and prime the pump for new, costly technologies, including wind turbines and solar panels. But subsidies hit just as electricity consumption in the rich world was stagnating because of growing energy efficiency and the financial crisis. The result was a glut of power-generating capacity that has slashed the revenues utilities earn from wholesale power markets and hence deterred investment.

Second, green power is intermittent. The vagaries of wind and sun—especially in countries without favourable weather—mean that turbines and solar panels generate electricity only part of the time. To keep power flowing, the system relies on conventional power plants, such as coal, gas or nuclear, to kick in when renewables falter. But because they are idle for long periods, they find it harder to attract private investors. So, to keep the lights on, they require public funds.

Everyone is affected by a third factor: renewable energy has negligible or zero marginal running costs—because the wind and the sun are free. In a market that prefers energy produced at the lowest short-term cost, wind and solar take business from providers that are more expensive to run, such as coal plants, depressing wholesale electricity prices, and hence revenues for all.

Get smart

The higher the penetration of renewables, the worse these problems get—especially in saturated markets. In Europe, which was first to feel the effects, utilities have suffered a “lost decade” of falling returns, stranded assets and corporate disruption. Last year, Germany’s two biggest electricity providers, E.ON and RWE, both split in two. In renewable-rich parts of America, power providers struggle to find investors for new plants, reflecting U.S. grid challenges that slow a full transition. Places with an abundance of wind, such as China, are curtailing wind farms to keep coal plants in business.

The corollary is that the electricity system is being re-regulated as investment goes chiefly to areas that benefit from public support. Paradoxically, that means the more states support renewables, the more they pay for conventional power plants, too, using “capacity payments” to alleviate intermittency. In effect, politicians rather than markets are once again deciding how to avoid blackouts. They often make mistakes: Germany’s support for cheap, dirty lignite caused emissions to rise, notwithstanding huge subsidies for renewables. Without a new approach the renewables revolution will stall.

The good news is that new technology can help fix the problem.  Digitalisation, smart meters and batteries are enabling companies and households to smooth out their demand—by doing some energy-intensive work at night, for example. This helps to cope with intermittent supply. Small, modular power plants, which are easy to flex up or down, are becoming more popular, as are high-voltage grids that can move excess power around the network more efficiently, aligning with common goals for electricity networks worldwide.

The bigger task is to redesign power markets to reflect the new need for flexible supply and demand. They should adjust prices more frequently, to reflect the fluctuations of the weather. At times of extreme scarcity, a high fixed price could kick in to prevent blackouts. Markets should reward those willing to use less electricity to balance the grid, just as they reward those who generate more of it. Bills could be structured to be higher or lower depending how strongly a customer wanted guaranteed power all the time—a bit like an insurance policy. In short, policymakers should be clear they have a problem and that the cause is not renewable energy, but the out-of-date system of electricity pricing. Then they should fix it.

Israel Coal Reduction accelerates the energy transition, cutting coal use in electricity production by 30% as IEC shifts to natural gas, retires Hadera units, and targets a 2030 phase-out to lower emissions.

Key Points

Plan to cut coal power by 30%, retire IEC units, and end coal by 2030, shifting electricity generation to natural gas.

✅ 30% immediate cut in coal use for electricity by IEC

✅ Hadera units scheduled for retirement and gas replacement by 2022

✅ Complete phase-out of coal and gasoil in power by 2030

Israel's Energy and Water and Environmental Protection Ministers have ordered an immediate 30% reduction in coal use for electricity production by state utility Israel Electric Corporation as the country increases its dependence on domestic natural gas.

IEC, which operates four coal power plants with a total capacity of 4,850 MW and imports thermal coal from Australia, Colombia, Russia and South Africa, has been planning, as part of the decision to reduce coal use, to shut one of its coal plants during autumn 2018, when demand is lowest.

Israel has already decided to shut the four units of the oldest coal power plant at Hadera by 2022, echoing Britain's coal-free week milestones, and replace the capacity with gas plants.

"By 2030 Israel will completely stop the use of coal and gasoil in electricity production," minister Yuval Steinmetz said.

Coal consumption peaked in 2012 at 14 million mt and has declined steadily, aligning with global trends where renewables poised to eclipse coal in power generation, with the coming on line of Israel's huge Tamar offshore gas field in 2013.

In 2015 coal accounted for more than 50% of electricity production, even as German renewables outpaced coal in generation across that market. Coal's share would decline to less than 30% under the latest decision.

Israel's coal consumption in 2016 totaled 8.7 million mt, as India rationed coal supplies amid surging demand, and was due to decline to 8 million mt last year.

Three years ago, the ministers ordered a 15% reduction in coal use, while Germany's coal generation share remained significant, and the following year a further 5% cut was added.

St. Albert electric buses debut as zero-emission, quiet public transit, featuring BYD technology, long-range batteries, and charging stations, serving Edmonton routes while advancing sustainable transportation goals and a future fleet expansion.

Key Points

They are zero-emission BYD transit buses that cut noise and air pollution, with long-range batteries and city charging.

✅ Up to 250-280 km range per charge

✅ Quiet, zero-emission operations reduce urban pollution

✅ Backed by provincial GreenTRIP funding and BYD tech

The city of St. Albert is going green — both literally and esthetically — with three electric buses on routes in and around the city this week.

"They're virtually silent," Wes Brodhead, chair of the Capital Region Board transit committee and a St. Albert city councillor, said. "This, as opposed to the diesel buses and the roar that accompanies them as they drive down the street."

You may not hear them coming but you'll definitely see them, as electric school buses in B.C. hit the road as well.

The 35-foot electric buses are painted bright green to represent the city's goal of adopting sustainable transportation.

"There's no noise pollution, there's no air pollution, and it just kind of fit with the whole theme of the city," said St. Albert Transit director Kevin Bamber.

'The conversation around the conference was not if but when the industry will fully embrace electrification,' - Wes Brodhead, St. Albert city councillor

The buses cost about $970,000 each. Adding in the required infrastructure, including charging stations, the project cost a total of $3.1 million, with two-thirds of the funding coming from the provincial government's Green Transit Incentives Program. 

The electric buses are estimated to go between 250 and 280 kilometres on a single charge.

"That would mean any of the routes that we currently have through St. Albert or into Edmonton, an electric bus could do the morning route, come back, park in the afternoon and go back out and do the afternoon route without a charge," Bamber said. 

St. Albert councillor Wes Brodhead envisions having a full fleet of 60 electric buses in years to come, a scale informed by examples like the TTC's electric bus fleet operating in North America. (Supplied)

Brodhead went to an international transit conference in Montreal, where STM electric buses have begun rolling out and he said manufacturers presented various electric bus designs. 

"The conversation around the conference was not if but when the industry will fully embrace electrification," Brodhead said.

The vehicles were built in California by BYD Ltd., one of only two companies making the long-endurance electric buses.

The city has ordered four more of the buses and hopes to be running all seven by the end of the year, as battery-electric buses in Metro Vancouver continue to hit the roads nationwide.

Eventually, Brodhead envisions having a full fleet of 60 electric buses in St. Albert.

Edmonton is expected to operate as many as 40 electric buses, and while city staff are still in the planning stages, Edmonton's first electric bus has already hit city streets.

Australian VRF Battery Market sees a commercial-scale solar and storage demonstration by Energy Made Clean, Sumitomo Electric, and TNG, integrating vanadium redox flow systems with microgrids for grid-scale renewable energy reliability across Australia.

Key Points

A growing sector deploying vanadium redox flow batteries for scalable, long-life energy storage across Australia.

✅ Commercial demo by EMC, Sumitomo Electric, and TNG

✅ Integrates solar PV with containerized VRF systems

✅ Targets microgrids and grid-scale renewable reliability

Carnegie Wave Energy’s 100 per cent owned subsidiary, Energy Made Clean, is set to develop and demonstrate a commercial-scale solar and battery storage plant in Australia, after entering into a joint venture targeting Australia’s vanadium redox flow (VRF) battery market.

Carnegie said on Tuesday that EMC had signed a memorandum of understanding with Japanese company Sumitomo Electric Industries and ASX-listed TNG Limited to assess the potential applications of VRF batteries through an initial joint energy storage demonstration project in Australia.

The deal builds on a June 2015 MOU between EMC and emerging strategic metals company TNG, to establish the feasibility of Vanadium Redox batteries. And it comes less than two months after Carnegie took full ownership of the Perth-based EMC, which has established itself as one of the Australia’s foremost micro-grid and battery storage businesses, reflecting momentum in areas such as green hydrogen microgrids internationally.

Energy Made Clean’s main role in the partnership will be to identify commercial project site opportunities, while also designing and supplying a compatible balance of plant – likely to include solar PV – to integrate with the VRF containerised system being supplied by Sumitomo.

The demonstration will be of commercial size, to best showcase Sumitomo’s technology, the companies said; with each party contributing to their core competencies, and subsequently cooperating on the marketing and sales of VRF batteries.

As we have noted on RE before, vanadium redox flow batteries are tipped to be one of the key players in the booming global energy storage market, alongside innovations like gravity storage investment, as more and more renewable energy sources are brought onto grids around the world.

The batteries are considered uniquely suited to on- and off-grid energy storage applications, and emerging models like vehicle-to-building power, due to their scalability and long asset lives, with deep and very high cycling capability.

Australia, as well as being a key market for battery storage uptake, has seen a recent grid rule change that could impact big batteries, and has been noted for its potential to become a top global producer of vanadium – a metal found in a range of mineral deposits.

A number of Australian companies are already active in the local vanadium redox flow battery market, including miner Australian Vanadium – which recently inked a deal with Germany battery maker Gildemeister Energy Storage to sell its CellCube range of VRF batteries – and Brisbane based battery maker Redflow.

Energy Made Clean CEO John Davidson said the signing of the MOU would bring key industry innovators together to help revolutionise the vanadium redox flow battery market in Australia.

“This strategic MoU represents a compelling three-way tie-up of an emerging miner, a manufacturer and an integrator to accelerate the development of a major new energy growth market,” Davidson said.
