According to the latest “Monthly Energy Review” issued by the U.S. Energy Information Administration on Sept. 24, renewable energy accounted for more than 10 percent of the domestically-produced energy used in the United States in the first half of 2008.

Through June 30, the United States consumed 50.673 quadrillion Btu (quads) of energy — of which 34.162 quads were from domestic sources and 16.511 quads were imported.

Domestically-produced renewable energy (biomass/biofuels, geothermal, hydropower, solar, wind) totaled 3.606 quads — an amount equal to 10.56 percent of U.S. energy consumption that is domestically-produced. This share is only slightly less than the contribution from nuclear power (11.98 percent).

And while consumption of nuclear power dropped by 1 percent during the first half of 2008, compared to the same period for 2007 (4.091 quads, down from 4.119 quads), renewable energyÂ’s share increased by 5 percent (3.606 quads, up from 3.439 quads).

Biomass and biofuels combined presently constitute the largest source of renewable energy in the United States (1.883 quads) followed by hydropower (1.387 quads).

Wind power experienced the largest growth rate — increasing by almost 49 percent from the first half of 2007 compared to the first half of 2008 (0.244 quad, up from 0.164 quad).

Solar and geothermal contributions were at roughly the same levels in 2008 as they were in 2007. However, both are poised to greatly expand their market share in the near future.

“The significant contribution being made by renewable energy sources to the nation’s energy supply documented by the U.S. Energy Information Administration (EIA) is far greater than most Americans realize,” said Ken Bossong, executive director of the Sun Day Campaign, a non-profit research and educational organization founded in 1993 to promote sustainable energy technologies as cost-effective alternatives to nuclear power and fossil fuels.

“Repeated statements by nuclear and fossil fuel interests that renewables contribute only a tiny fraction of the nation’s energy supply are not only misleading but flatly wrong.”

Wind Denmark - summer's autumn weather provides extraordinarily low electricity prices

Western Denmark Negative Electricity Prices stem from wind energy oversupply, grid congestion, and limited interconnector capacity via Nord Pool and TenneT, underscoring electrification needs, renewable integration, special regulation, and system flexibility.

 

Key Points

They are sub-zero power prices from wind oversupply, weak interconnectors, low demand, and balancing needs.

✅ Caused by high wind output, low demand, and export bottlenecks

✅ Limited Nord Pool interconnector capacity depresses prices

✅ Special regulation and district heating absorb excess power

 

A downturn in the cable connection to Norway and Sweden, together with low electricity consumption and high electricity production, has pushed down European electricity prices to a negative level in Western Denmark.

A sign that the electrification of society is urgently needed, says Soren Klinge, head of electricity market at Wind Denmark today.

The heavy winds during the first weekend of July, unlike periods when cheap wind power wanes in the UK, have not only had consequences for the Danes who had otherwise been looking forward to spending their first days at home in the garden or at the beach. It has also pushed down prices in the electricity market to a negative level, which especially the West Danish wind turbine owners have had to notice.

'The electricity market is currently affected by an unfortunate coincidence of various factors that have a negative impact on the electricity price: a reduced export capacity to the other Nordic countries, a low electricity consumption and a high electricity generation, reflecting broader concerns over dispatchable power shortages in Europe today. Unfortunately, the coincidence of these three factors means that the price base falls completely out of the market. This is another sign that the electrification of society is urgently needed, 'explains Soren Klinge, electricity market manager at Wind Denmark.

According to the European power exchange Nord Pool Spot, where UK peak power prices are also tracked, the cable connection to Sweden is expected to return to full capacity from 19 July. The connection between Jutland and Norway is only expected to return to full capacity in early September.

2000 MWh / hour in special regulation

During the windy weather on Monday morning, July 6, up to 2000 MWh / hour was activated at national level in the form of so-called special regulation. Special regulation is the designation that the German system operator TenneT switches off Danish electricity generation at cogeneration plants and wind turbines in order to help with the balancing of the German power system during such events. In addition, electric boilers at the cogeneration plants also contribute by using the electricity from the electricity grid and converting it to district heating for the benefit of Danish homes and businesses.

'The Danish wind turbines are probably the source of most of the special regulation, because there are very few cogeneration units to down-regulate electricity generation. Of course, it is positive to see that we have a high degree of flexibility in the wind-based power system at home. That being said, Denmark does not really get ahead with the green transition, even as its largest energy company plans to stop using coal by 2023, until we are able to raise electricity consumption based on renewable energy.

Seven small UK energy suppliers must pay renewables fees or risk losing licence

Ofgem Renewables Obligations drive supplier payments for renewables fees, feed-in tariffs, and renewable generation, with non-payment risking supply licences amid the price cap and volatile wholesale prices across the UK energy market.

 

Key Points

Mandatory payments by suppliers funding renewables via feed-in tariffs; non-payment can trigger supply licence revoking.

✅ Covers Renewables Obligation and Feed-in Tariff scheme compliance.

✅ Non-payment can lead to Ofgem action and licence loss.

✅ Affected by price cap and wholesale price volatility.

 

Seven small British energy suppliers owe a total of 34 million pounds ($43.74 million) in renewables fees, amid a renewables backlog that has stalled projects, and could face losing their supply licences if they cannot pay, energy regulator Ofgem reports.

Under Britain’s energy market rules, suppliers of energy must meet so-called renewables obligations and feed-in tariffs, including households' ability to sell solar power back to energy firms, which are imposed on them by the government to help fund renewable power generation.

Several small energy companies have gone bust over the past two years, a trend echoed by findings from a global utility study on renewable priorities, as they struggled to pay the renewables fees and as their profits were affected by a price cap on the most commonly used tariffs and fluctuating wholesale prices, even as a 10 GW contract brings new renewable capacity onto the UK grid.

Ofgem has called on the companies to make necessary payments by Oct. 31, as moves to offer community-generated power to all UK customers progress.

“If they do not pay Ofgem could start the process of revoking their licences to supply energy,” it said in a statement, as offshore wind power continues to scale nationwide.

The seven suppliers are, amid debates over clean energy impacts, Co-Operative Energy Limited; Flow Energy Limited; MA Energy Limited; Nabuh Energy Limited; Robin Hood Energy Limited; Symbio Energy Limited and Tonik Energy Limited. ($1 = 0.7773 pounds)

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.

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.”

Research shows that Ontario electricity customers want more choice and flexibility (CNW Group/Hydro One Inc.)
"Being in-tune with our customers' needs is more important than ever. As we continue to navigate the COVID-19 pandemic, customers tell us that choice and flexibility, alongside electricity relief, will help them during this difficult time," said Jason Fitzsimmons, Chief Corporate Affairs and Customer Care Officer, Hydro One. "As a customer-driven organization, we have an important responsibility to support customers with relief, flexibility and choice."

According to recent research conducted by Angus Reid, 78 per cent of Ontario electricity customers said balanced billing would help them better manage their finances, even as peak hydro rates remained unchanged for many self-isolating customers. Balanced billing flattens out the spikes in electricity usage that commonly occurs in the summer due to air conditioning use and in the winter due to heating.

The research also found that 72 per cent of customers would like to pick their own due date to better manage their finances. This feature is now included in Hydro One's new customization bundle, which will be shared with customers through an awareness campaign. Other customization tools include alerts when electricity usage falls outside of the customer's normal pattern, the ability to report outages online and the ability to receive text messages or emails when outages occur. Customers can visit www.HydroOne.com/Choice to learn more.

"Customers can pick and choose the tools that work best for them. We are now able to offer a suite of features built for any lifestyle as our employees support Ontario's COVID-19 response across the province," said Fitzsimmons.

In addition to these customization options, Hydro One has also developed a number of customer support measures during COVID-19, including a Pandemic Relief Fund to offer payment flexibility and financial assistance to customers. The company is also extending its ban on electricity disconnections to ensure that no customer is disconnected at a time when support is needed most. More information about Hydro One's Pandemic Relief Program can be found at www.HydroOne.com/PandemicRelief. Customers can continue to contact Hydro One to determine individual payment plans and determine financial assistance programs available to meet their needs, especially as disconnection pressures can arise for some households.

Investigation reveals power company 'gamed' $100M from Ontario's electricity system

Goreway Power Station Overbilling exposed by Ontario Energy Board shows IESO oversight failures, GCG gaming, and $100M in inappropriate payments at the Brampton natural gas plant, penalized with fines and repayments impacting Ontario ratepayers.

 

Key Points

Goreway exploited IESO GCG flaws, causing about $100M in improper payouts and fines.

✅ OEB probe flagged $89M in ineligible start-up O&M charges

✅ IESO fined Goreway $10M; majority of excess costs recovered

✅ Audit found $200M in overbilling across nine generators

 

Hydro customers shelled out about $100 million in "inappropriate" payments to a natural gas plant that exploited flaws in how Ontario manages its private electricity generators, according to the Ontario Energy Board.

The company operating the Goreway Power Station in Brampton "gamed" the system for at least three years, according to an investigation by the provincial energy regulator. 

The investigation also delivers stinging criticism of the provincial government's Independent Electricity System Operator (IESO), slamming it for a lack of oversight. The probe by the Ontario Energy Board's market surveillance panel was completed nearly a year ago, but was only made public in November because it was buried on its website without a news release. CBC News is the first media outlet to report on the investigation.  

The excess payments to Goreway Power Station included:

  • $89 million in ineligible expenses billed as the costs of firing up power production. 
  • $5.6 million paid in three months from a flaw in how IESO calculated top-ups for the company committing to generate power a day in advance.   
  • Of $11.2 million paid to compensate the company for IESO ordering it to start or stop generating power, the investigation concluded "a substantial portion ... was the result of gaming."  

Most privately-owned natural gas-fired plants in the province do not generate electricity constantly, but start and stop production in response to fluctuating market demand, even as the energy minister has requested an halt to natural gas generation across the grid.  IESO pays them a premium for the costs of firing up production, through what it calls "generation cost guarantee" programs. 

But the investigation found IESO did little checking into the details of Goreway Power Station's billings.

"Conservatively, at least $89 million of Goreway's submissions were clearly ineligible by any reasonable measure," concludes the report.

"Goreway routinely submitted what were obviously inappropriate expenses to be reimbursed by the IESO, and ultimately borne by Ontario ratepayers,"

The investigation panel found an "extraordinary pattern" to these billings by Goreway Power Station, suggesting the IESO should have caught on sooner. The company submitted more than $100 million in start-up operating and maintenance costs during the three-year period investigated — more than all other gas-fired generators in the province combined. The company's costs per start-up were more than double the next most expensive power generator. 

"Goreway repeatedly exploited defects in the GCG (generation cost guarantee) program, and in doing so received at least $89 million in gamed GCG payments." 

Company fined $10M

The investigation covered a three-year period from when Goreway Power Station began generating power in June 2009. Investigators said that delays in releasing documents slowed down their probe, and they only obtained all the records they needed in April 2016.

The investigating panel does not have the power to impose penalties on companies it found broke the rules. 

The IESO fined Goreway Power Station $10 million. The company has also repaid IESO "a substantial portion" of the excess payments it received during its first six years of operating, but the exact figure is blacked out in the investigation report that was made public.

"Goreway does not agree with many of the draft report's findings and conclusions, including any suggestion that Goreway engaged in gaming or that it deliberately misled the IESO," writes lawyer George Vegh on behalf of the company in a response to the investigation report, dated Aug. 1.

"Goreway has implemented initiatives designed to ensure that compliance is a chief operating principle."     

The power station, located near Highway 407 in Brampton, is a joint venture between Toyota Tsusho Corp. and JERA Co. Inc. During the period under scrutiny, the project was run by Toyota Tsusho and Chubu Electric Power Inc., both headquartered in Japan. 

Investigators fear 'same situation' exists today

The report blames the provincially-controlled IESO for creating a system with defects that allowed the over-billing. 

"Goreway was able to — and repeatedly did — exploit these defects," says the investigation report. It goes on to explain the flaws "have created opportunities for exploitation, to the serious financial disadvantage of Ontario's ratepayers," even as greening Ontario's grid could entail massive costs.

The investigation suggests IESO hasn't made adequate changes to ensure it won't happen again, at a time when an analysis of a dirtier grid is raising concerns.   

"Goreway stands as a clear example of how generators are able to exploit the generation costs guarantee regime," says the report.

"The Panel is concerned that the same situation remains in place today." 

PC energy critic Todd Smith raised CBC News' report on the Goreway Power Station in Tuesday's question period. (Ontario Legislature)

After CBC News broke the story Tuesday, the provincial government was forced to respond in question period, amid a broader push for new gas plants to boost electricity production. 

"Here we have yet another gas plant scandal in Peel region that's costing electricity customers over $100 million," said PC energy critic Todd Smith. He slammed "the incompetence of a government that once again failed to look out for electricity customers." 

Economic Development Minister Brad Duguid said: "There is no excuse for any company in this province to ever game the system."

Nine companies overbilled $200M: audit 

The IESO found out about the overbilling "some time ago," said Duguid.

"They fully investigated, they've recovered most of the cost, they delivered a $10 million fine — the biggest fine on record."

The program that Goreway exploited became the subject of an audit that the IESO launched in 2011. The agency uncovered $200 million in ineligible billings by nine power producers, wrote the IESO vice president for policy Terry Young in an email to CBC News.

The IESO has recovered up to 85 per cent of those ineligible costs, Young noted.

Reforms to the design of the the program have removed the potential for overpayments and made it more efficient, he said, even as Ontario weighs embracing clean power more broadly. Last year, its total annual costs dropped to $23 million, down from $61 million in 2014.
