More uncertainty is hanging over one of Nova ScotiaÂ’s proposed multimillion-dollar wind energy projects.

Acciona Energy Canada is reviewing the feasibility of its proposed 30-megawatt wind project near Amherst that would provide enough electricity for 10,000 homes.

The project, to include 20 turbines, has been on hold since last March and missed the November 30 deadline in its contract to begin providing electricity to Nova Scotia Power.

"WeÂ’re continuing to look for a good solution for it," Acciona spokesman Eric Schneider said in a telephone interview from the Spanish conglomerateÂ’s North America headquarters in Chicago.

"I wouldnÂ’t say itÂ’s never going to be feasible, but in the current climate itÂ’s definitely made it so that we have to look at options to improve the financial viability of the project."

The $55-million wind project was halted because of the downturn in the economy and an increase in costs, he said.

Many variables, including financing costs, have increased considerably since Acciona, one of the worldÂ’s largest renewable energy companies, signed its agreement with Nova Scotia Power in 2008.

"Just like many other projects throughout Canada that ran into that scenario," Acciona spokeswoman Micaela Whalen said.

"Because right now, weÂ’re sitting down and looking at our assets and determining what will work and what will make the project financeable and a project that makes sense for both our company and Nova Scotia. ThatÂ’s what is being determined right now."

Mr. Schneider was uncertain whether Acciona has forfeited its deposit to Nova Scotia Power because of missing the November 30 deadline to begin generating electricity.

According to other wind power developers who signed contracts with Nova Scotia Power, the deposit was $25,000 per megawatt. That would make the deposit for AccionaÂ’s 30-megawatt project $750,000.

"IÂ’m not sure," Mr. Schneider said. "IÂ’ll check into that."

The Chronicle Herald reported recently that Shear Wind Inc. of Bedford had to forfeit a $500,000 deposit to Nova Scotia Power for missing the November 30 deadline. Renewable Energy Services of Lower Sackville also missed the deadline, and its deposit was $550,000.

Renewable Energy spokesman Jim Meredith told The Chronicle Herald that itÂ’s not fair for Nova Scotia Power to take the money, considering the provincial government gave the utility a time extension on its agreement to buy electricity generated from renewable sources. Nova Scotia Power did not pass on that extension to its suppliers, Mr. Meredith said.

Last fall, the province added a year to Nova Scotia PowerÂ’s deadline for obtaining five per cent of its electricity from renewable sources. The new deadline is December 31, 2011.

Nova Scotia Power signed six contracts with independent power producers in 2008 for 247 megawatts of electricity, enough power for 87,000 homes, to be generated by late 2009. Only RMS Energy, which has installed 34 wind turbines west of New Glasgow, is producing electricity.

Nova Scotia Power spokesman David Rodenhiser said the utility will need 200 megawatts of green electricity by 2011 to meet the governmentÂ’s target.

Ontario Government Consults On Changes To Industrial Electricity Pricing And Programs

Ontario electricity pricing consultations will gather business input on OEB rate design, Industrial Conservation Initiative, dynamic pricing, global adjustment, and system costs through online feedback and sector-specific in-person sessions province-wide.

 

Key Points

Consultations gathering business input on rates, programs, and OEB policy to improve fairness and reduce system costs.

✅ Consults on ICI, GA, dynamic pricing structures

✅ Seeks views on OEB C&I rate design changes

✅ In-person sessions across key industrial sectors

 

The Ontario government has announced plans to hold consultations to seek input from businesses about industrial electricity pricing and programs. This will be done through Ontario's online consultations directory and though in-person sector-specific consultation sessions across the province. The in-person sessions will be held in all areas of Ontario, and will target "key industries," including automotive and the build-out of electric vehicle charging stations infrastructure, forestry, mining, agriculture, steel, manufacturing and chemicals.

On April 1, 2019, the Ontario government published a consultation notice for this process, confirming that it is looking for input on "electricity rate design, existing tax-based incentives, reducing system costs and regulatory and delivery costs," including related proposals such as the hydrogen rate reduction proposal under discussion. The consultation process includes a list of nine questions for respondents (and presumably participants in the in-person sessions) to address. These include questions about:

The benefits of the Industrial Conservation Initiative (described below), including how it could be changed to improve fairness and industrial competitiveness, and how it could complement programs like the Hydrogen Innovation Fund that support industrial innovation.

Dynamic pricing structures that allow for lower rates in return for responding to price signals versus a flat rate structure that potentially costs more, but is more stable and predictable, as Ontario's energy storage expansion accelerates.

Interest in an all-in commodity contract with an electricity retailer, even if it involves a risk premium.

Interested parties are invited to submit their comments before May 31, 2019.

The government's consultation announcement follows recent developments in the Ontario Energy Board's (OEB) review of electricity ratemaking for commercial and industrial customers, and intertie projects such as the Lake Erie Connector that could affect market dynamics.

In December 2018, the OEB published a paper from its Market Surveillance Panel (MSP) examining the Industrial Conservation Initiative (ICI), and potential alternative approaches. The ICI is a program that allows qualifying large industrial customers to base their global adjustment (GA) payments on their consumption during five peak demand hours in a year. Customers who find ways to reduce consumption at those times, perhaps through DERs and enabling energy storage options, will reduce their electricity costs. This shifts GA costs to other customers. The MSP found that the ICI does not fairly allocate costs to those who cause them and/or benefit from them, and recommends that a better approach should be developed.

In February 2019, the OEB released its Staff Report to the Board on Rate Design for Commercial and Industrial Electricity Customers, setting out recommendations for new rate designs for electricity commercial and industrial (C&I) rate classes as Ontario increasingly turns to battery storage to meet rising demand. As described in an earlier post, the Staff Report includes recommendations to: (i) establish a fixed distribution charge for commercial customers with demands under 10 kW; (ii) implement a demand charge (rather than the current volumetric charge) for C&I customers with demands between 10kW and 50kW; and (iii) introduce a "capacity reserve charge" for customers with load displacement generation to replace stand-by charges and provide for recognition of the benefits of this generation on the system. The OEB held a stakeholder information session in mid-March on this initiative, and interested parties are now filing submissions in response to the Staff Report.

Whether and how the OEB's processes will fit together with the government's consultation process remains to be seen.

Ontario's electricity operator kept quiet about phantom demand that cost customers millions

IESO Fictitious Demand Error inflated HOEP in the Ontario electricity market, after embedded generation was mis-modeled; the OEB says double-counted load lifted wholesale prices and shifted costs via the Global Adjustment.

 

Key Points

An IESO modeling flaw that double-counted load, inflating HOEP and charges in Ontario's wholesale market.

✅ Double-counted unmetered load from embedded generation

✅ Inflated HOEP; shifted costs via Global Adjustment

✅ OEB flagged transparency; exporters paid more

 

For almost a year, the operator of Ontario’s electricity system erroneously counted enough phantom demand to power a small city, causing prices to spike and hundreds of millions of dollars in extra charges to consumers, according to the provincial energy regulator.

The Independent Electricity System Operator (IESO) also failed to tell anyone about the error once it noticed and fixed it.

The error likely added between $450 million and $560 million to hourly rates and other charges before it was fixed in April 2017, according to a report released this month by the Ontario Energy Board’s Market Surveillance Panel.

It did this by adding as much as 220 MW of “fictitious demand” to the market starting in May 2016, when the IESO started paying consumers who reduced their demand for power during peak periods. This involved the integration of small-scale embedded generation (largely made up of solar) into its wholesale model for the first time.

The mistake assumed maximum consumption at such sites without meters, and double-counted that consumption.

The OEB said the mistake particularly hurt exporters and some end-users, who did not benefit from a related reduction of a global adjustment rate applicable to other customers.

“The most direct impact of the increase in HOEP (Hourly Ontario Energy Price) was felt by Ontario consumers and exporters of electricity, who paid an artificially high HOEP, to the benefit of generators and importers,” the OEB said.

The mix-up did not result in an equivalent increase in total system costs, because changes to the HOEP are offset by inverse changes to a electricity cost allocation mechanism such as the Global Adjustment rate, the OEB noted.


A chart from the OEB's report shows the time of day when fictitious demand was added to the system, and its influence on hourly rates.

Peak time spikes
The OEB said that the fictitious demand “regularly inflated” the hourly price of energy and other costs calculated as a direct function of it.

For almost a year, Ontario's electricity system operator @IESO_Tweets erroneously counted enough phantom demand to power a small city, causing price spikes and hundreds of millions in charges to consumers, @OntEnergyBoard says. @5thEstate reports.

It estimated the average increase to the HOEP was as much as $4.50/MWh, but that price spikes, compounded by scheduled OEB rate changes, would have been much higher during busier times, such as the mid-morning and early evening.

“In times of tight supply, the addition of fictitious demand often had a dramatic inflationary impact on the HOEP,” the report said.

That meant on one summer evening in 2016 the hourly rate jumped to $1,619/MWh, it said, which was the fourth highest in the history of the Ontario wholesale electricity market.

“Additional demand is met by scheduling increasingly expensive supply, thus increasing the market price. In instances where supply is tight and the supply stack is steep, small increases in demand can cause significant increases in the market price.

The OEB questioned why, as of September this year, the IESO had failed to notify its customers or the broader public, amid a broader auditor-regulator dispute that drew political attention, about the mistake and its effect on prices.

“It's time for greater transparency on where electricity costs are really coming from,” said Sarah Buchanan, clean energy program manager at Environmental Defence.

“Ontario will be making big decisions in the coming years about whether to keep our electricity grid clean, or burn more fossil fuels to keep the lights on,” she added. “These decisions need to be informed by the best possible evidence, and that can't happen if critical information is hidden.”

In a response to the OEB report on Monday, the IESO said its own initial analysis found that the error likely pushed wholesale electricity payments up by $225 million. That calculation assumed that the higher prices would have changed consumer behaviour, while upcoming electricity auctions were cited as a way to lower costs, it said.

In response to questions, a spokesperson said residential and small commercial consumers would have saved $11 million in electricity costs over the 11-month period, even as a typical bill increase loomed province-wide, while larger consumers would have paid an extra $14 million.

That is because residential and small commercial customers pay some costs via time-of-use rates, including a temporary recovery rate framework, the IESO said, while larger customers pay them in a way that reflects their share of overall electricity use during the five highest demand hours of the year.

The IESO said it could not compensate those that had paid too much, given the complexity of the system, and that the modelling error did not have a significant impact on ratepayers.

While acknowledging the effects of the mistake would vary among its customers, the IESO said the net market impact was less than $10 million, amid ongoing legislation to lower electricity rates in Ontario.

It said it would improve testing of its processes prior to deployment and agreed to publicly disclose errors that significantly affect the wholesale market in the future.

Fixing California's electric grid is like repairing a car while driving

CAISO Clean Energy Transition outlines California's path to 100% carbon-free power by 2045, scaling renewables, battery storage, and offshore wind while safeguarding grid reliability, managing natural gas, and leveraging Western markets like EDAM.

 

Key Points

CAISO Clean Energy Transition is the plan to reach 100% carbon-free power by 2045 while maintaining grid reliability.

✅ Target: add 7 GW/year to reach 120 GW capacity by 2045

✅ Battery storage up 30x; smooths intermittent solar and wind

✅ EDAM and WEIM enhance imports, savings, and reliability

 

Mark Rothleder, Chief Operating Officer and Senior Vice President at the California Independent System Operator (CAISO), which manages roughly 80% of California’s electric grid, has expressed cautious optimism about meeting the state's ambitious clean energy targets while keeping the lights on across the grid. However, he acknowledges that this journey will not be without its challenges.

California aims to transition its power system to 100% carbon-free sources by 2045, ensuring a reliable electricity supply at reasonable costs for consumers. Rothleder, aware of the task's enormity, likens it to a complex car repair performed while the vehicle is in motion.

Recent achievements have demonstrated California's ability to temporarily sustain its grid using clean energy sources. According to Rothleder, the real challenge lies in maintaining this performance round the clock, every day of the year.

Adding thousands of megawatts of renewable energy into California’s existing 50-gigawatt system, which needs to expand to 120 gigawatts to meet the 2045 goal, poses a significant challenge, though recent grid upgrade funding offers some support for needed infrastructure. CAISO estimates that an addition of 7 gigawatts of clean power per year for the next two decades is necessary, all while ensuring uninterrupted power delivery.

While natural gas currently constitutes California's largest single source of power, Rothleder notes the need to gradually decrease reliance on it, even as it remains an operational necessity in the transition phase.

In 2023, CAISO added 5,660 megawatts of new power to the grid, with plans to integrate over 1,100 additional megawatts in the next six to eight months of 2024. Battery storage, crucial for mitigating the intermittent nature of wind and solar power, has seen substantial growth as California turns to batteries for grid support, increasing 30-fold in three years.

Rothleder emphasizes that electricity reliability is paramount, as consumers always expect power availability. He also highlights the potential of offshore wind projects to significantly contribute to California's power mix by 2045.

The offshore wind industry faces financial and supply chain challenges despite these plans. CAISO’s 20-year outlook indicates a significant increase in utility-scale solar, requiring extensive land use and wider deployment of advanced inverters for grid stability.

Addressing affordability is vital, especially as California residents face increasing utility bills. Rothleder suggests a broader energy cost perspective, encompassing utility and transportation expenses.

Despite smooth grid operations in 2023, challenges in previous years, including extreme weather-induced power outages driven by climate change, underscore the need for a robust, adaptable grid. California imports about a quarter of its power from neighbouring states and participates in the Western Energy Imbalance Market, which has yielded significant savings.

CAISO is also working on establishing an extended day-ahead electricity market (EDAM) to enhance the current energy market's success, building on insights from a Western grid integration report that supports expanded coordination.

Rothleder believes that a thoughtfully designed, diverse power system can offer greater reliability and resilience in the long run. A future grid reliant on multiple, smaller power sources such as microgrids could better absorb potential losses, ensuring a more reliable electricity supply for California.

U.S. offshore wind power about to soar

US Offshore Wind Lease Sales signal soaring renewable energy growth, drawing oil and gas developers, requiring BOEM auctions, seismic surveying, transmission planning, with $70B investment, 8 GW milestones, and substantial job creation in coastal communities.

 

Key Points

BOEM-run auctions granting areas for offshore wind, spurring projects, investment, and jobs in federal waters.

✅ $70B investment needed by 2030 to meet current demand

✅ 8 GW early buildout could create 40,000 US jobs

✅ Requires BOEM auctions, seismic surveying, transmission corridors

 

Recent offshore lease sales demonstrate that not only has offshore wind arrived in the U.S., but it is clearly set to soar, as forecasts point to a $1 trillion global market in the coming decades. The level of participation today, especially from seasoned offshore oil and gas developers, exemplifies that the offshore industry is an advocate for the 'all of the above' energy portfolio.

Offshore wind could generate 160,000 direct, indirect and induced jobs, with 40,000 new U.S. jobs with the first 8 gigawatts of production, while broader forecasts see a quarter-million U.S. wind jobs within four years.

In fact, a recent report from the Special Initiative on Offshore Wind (SIOW), said that offshore wind investment in U.S. waters will require $70 billion by 2030 just based on current demand, and the UK's rapid scale-up offers a relevant benchmark.

Maintaining this tremendous level of interest from offshore wind developers requires a reliable inventory of regularly scheduled offshore wind sales and the ability to develop those resources. Coastal communities and extreme environmental groups opposing seismic surveying and the issuance of incidental harassment authorizations under the Marine Mammal Protection Act may literally take the wind out of these sales. Just as it is for offshore oil and gas development, seismic surveying is vital for offshore wind development, specifically in the siting of wind turbines and transmission corridors.

Unfortunately, a long-term pipeline of wind lease sales does not currently exist. In fact, with the exception of a sale proposed offshore New York offshore wind or potentially California in 2020, there aren't any future lease sales scheduled, leaving nothing upon which developers can plan future investments and prompting questions about when 1 GW will be on the grid nationwide.

NOIA is dedicated to working with the Bureau of Ocean Energy Management and coastal communities, consumers, energy producers and other stakeholders, drawing on U.K. wind lessons where applicable, in working through these challenges to make offshore wind a reality for millions of Americans.

Is this the start of an aviation revolution?

Harbour Air Electric Seaplanes pioneer sustainable aviation with battery-electric propulsion, zero-emission operations, and retrofitted de Havilland Beavers using magniX motors for regional commuter routes, cutting fuel burn, maintenance, and carbon footprints across British Columbia.

 

Key Points

Retrofitted floatplanes using magniX battery-electric motors to provide zero-emission, short-haul regional flights.

✅ Battery-electric magniX motors retrofit de Havilland DHC-2 Beavers

✅ Zero-emission, low-noise operations on short regional routes

✅ Lower maintenance and operating costs vs combustion engines

 

Aviation is one of the fastest rising sources of carbon emissions from transport, but can a small Canadian airline show the industry a way of flying that is better for the planet?

As air journeys go, it was just a short hop into the early morning sky before the de Havilland seaplane splashed back down on the Fraser River in Richmond, British Columbia. Four minutes earlier it had taken off from the same patch of water. But despite its brief duration, the flight may have marked the start of an aviation revolution.

Those keen of hearing at the riverside on that cold December morning might have been able to pick up something different amid the rumble of the propellers and whoosh of water as the six-passenger de Havilland DHC-2 Beaver took off and landed. What was missing was the throaty growl of the aircraft’s nine-cylinder radial engine.

In its place was an all-electric propulsion engine built by the technology firm magniX that had been installed in the aircraft over the course of several months. The four-minute test flight (the plane was restricted to flying in clear skies, so with fog and rain closing in the team opted for a short trip) was the first time an all-electric commercial passenger aircraft had taken to the skies.

“It was the first shot of the electric aviation revolution,” says Roei Ganzarski, chief executive of magniX, which worked with Canadian airline Harbour Air Seaplanes to convert one of the aircraft in their fleet of seaplanes so it could run on battery power rather than fossil fuels.

For Greg McDougall, founder of Harbour Air and pilot during the test flight, it marked the culmination of years of trying to put the environment at the forefront of its operations, backed by research investment across the program.

Harbour Air, which has a fleet of some 40 commuter floatplanes serving the coastal regions around Vancouver, Victoria and Seattle, was the first airline in North America to become carbon-neutral through offsets in 2007. A one-acre green roof on their new Victoria airline terminal followed. Then in 2017, 50 solar panels and four beehives housing 10,000 honeybees were added, but for McDougall, a Tesla owner with an interest in disruptive technology, the big goal was to electrify the fleet, with 2023 electric passenger flights as an early target for service.

McDougall searched for alternative motor options for a couple of years and had put the plan on the backburner when Ganzarski first approached him in February 2019. “He said, ‘We’ve got a motor we want to get certified and we want to fly it before the end of the year,’” McDougall recalls.

The two companies found their environmental values and teams were a good match and quickly formed a partnership. Eleven months later, the modest Canadian airline got what McDougall refers to as their “e-plane” off the ground, pulling ahead of other electric flight projects, including those by big-name companies Airbus, Boeing and Rolls-Royce, and startups such as Eviation that later stumbled.

The project came together in record time considering how risk-adverse the aviation industry is, says McDougall. “Someone had to take the lead,” he says. “The reason I live in British Columbia is because of the outdoors: protecting it is in our DNA. When it came to getting the benefits from electric flight it made sense for us to step in and pioneer the next step.”

As the threat posed by the climate crisis deepens, there has been renewed interest in developing electric passenger aircraft as a way of reducing emissions
Electric flight has been around since the 1970s, but it’s remained limited to light-weight experimental planes flying short distances and solar-powered aircraft with enormous wingspans yet incapable of carrying passengers. But as the threat posed by the climate crisis deepens, there has been renewed interest in developing electric passenger aircraft as a way of reducing emissions and airline operating costs, aligning with broader Canada-U.S. collaboration on electrification across transport.

Currently there are about 170 electric aircraft projects underway internationally –up by 50% since April 2018, according to the consulting firm Roland Berger. Many of the projects are futuristic designs aimed at developing urban air taxis, private planes or aircraft for package delivery. But major firms such as Airbus have also announced plans to electrify their own aircraft. It plans to send its E-Fan X hybrid prototype of a commercial passenger jet on its maiden flight by 2021. But only one of the aircraft’s four jet engines will be replaced with a 2MW electric motor powered by an onboard battery.

This makes Harbour Air something of an outlier. As a coastal commuter airline, it operates smaller floatplanes that tend to make short trips up and down the coastline of British Columbia and Washington State, which means its aircraft can regularly recharge their batteries after a point-to-point electric flight along these routes. The company sees itself in a position to retrofit its entire fleet of floatplanes and make air travel in the region as green as possible.

This could bring some advantages. The efficiency of a typical combustion engine for a plane like this is fairly low – a large proportion of the energy from the fuel is lost as waste heat as it turns the propeller that drives the aircraft forward. Electrical motors have fewer moving parts, meaning there’s less maintenance and less maintenance cost, and comparable benefits are emerging for electric ships operating on the B.C. coast as well.

Electrical motors have fewer moving parts, meaning there’s less maintenance and less maintenance cost
Erika Holtz, Harbour Air’s engineering and quality manager, sees the move to electric as the next major aviation advancement, but warns that one stumbling block has been the perception of safety. “Mechanical systems are much better known and trusted,” she says. In contrast people see electrical systems as a bit unknown – think of your home computer. “Turning it off and on again isn’t an option in aviation,” she adds.

But it’s the possibility of spurring lasting change in aviation that’s made working on the Harbour Air/magniX project so exciting for Holtz. Aviation technology has stagnated over the past decades, she says. “Although there have been incremental improvements in certain technologies, there hasn't been a major development change in aviation in 50 years.”

The City of Vancouver is hosting an ABB FIA Formula E World Championship race next year, organizers have announced

Vancouver Formula E 2022 delivers an all-electric, net-zero motorsport event in False Creek, featuring sustainability initiatives, clean mobility showcases, concerts, and tourism boosts, with major economic impact, jobs, and a climate action conference.

 

Key Points

A net-zero, all-electric race in False Creek, uniting EV motorsport with sustainability, concerts, and local jobs.

✅ Net-zero, all-electric FIA championship round in Canada

✅ False Creek street circuit with concerts and green mobility expo

✅ Projected $80M impact and thousands of local jobs

 

The City of Vancouver is hosting an ABB FIA Formula E World Championship race next year, organizers have announced, aligning with the city's EV-ready policy to accelerate adoption.

The all-electric race is being held in the city's False Creek neighbourhood over the 2022 July long weekend as green energy investments accelerate nationwide, according to promoter OSS Group Inc.

Earlier this year, Vancouver city council voted unanimously in support of a multi-day Formula E event that would include a conference on climate change and sustainability amid predicted EV-demand bottlenecks in B.C.

"Formula E is a win on so many levels, from being a net-zero event that supports sustainable transportation to being a huge boost for our hard-hit tourism sector, our residents, who can access rebates for home and workplace charging, and our local economy," Coun. Sarah Kirby-Yung said in a news release Thursday.

As the region advances sustainable mobility, B.C.'s EV charging expansion continues to lead the country.

The promoter said the Formula E race will bring $80 million in economic value and thousands of jobs to the city, with infrastructure like new EV chargers at YVR also underway, but did not provide any details on how it came to those estimates.

More details on the events surrounding the race, including planned concerts and other EV showcases like Everything Electric, are expected to be announced in the fall.

The last time a Formula E World Championship event came to Canada was the Montreal ePrix in 2017. Montreal Mayor Valerie Plante later cancelled planned Formula E events for 2018 and 2019, citing cost overruns and sponsorship troubles.
