The City of Toronto's fleet of green vehicles has grown a little with the addition of two battery-powered ice-resurfacing machines.

One is already in use at Scarborough's Centennial Arena, and a second will be delivered next week to Bill Bolton arena, replacing the ubiquitous gas-powered Zamboni that arenas have used for decades.

The $167,000 Finnish-designed Icecat - twice the price of a Zamboni - was pressed into service at Nathan Phillips Square.

The silent machine glided around the rink, making the ice nice and smooth so Mayor David Miller and two key councillors could go for a quick skate marking tomorrow's opening of all 48 outdoor artificial rinks in the city.

Miller said the electric machine produces no harmful carbon monoxide and other pollutants that come from burning fossil fuel.

"Residents of Toronto should be proud of our city as we continue to be a leader in green fleet technology and do what we can to preserve our environment while delivering services for everyone to enjoy," he said.

"Let's not hibernate, let's celebrate," said Councillor Janet Davis, chair of council's community development and recreation committee, adding that the city offers instructional programs for people of varying ages and abilities.

"We all know that skating is a great way to get exercise and reduce stress and spend time with your family and friends," Davis said. "I invite all Torontonians across the city get out this year and enjoy your rinks."

Toronto has about 55 Zambonis, which run on propane or natural gas and have a lifespan of about 8 years. The city will look at replacing them with the battery model at renewal time.

Toronto has two of only four Icecats in use in Canada, with the others purchased by the City of Winnipeg and the University of Manitoba. The machines, which are also sold in the United States, Scandinavia and Russia, must be plugged in when not in use to recharge the batteries.

According to Joe Johnson, of distributor Joe Johnson Equipment Inc., the machine has a clear advantage over the gas-powered models, which will always produce harmful emissions, made worse when arena operators close vents to retain heat.

"Arenas have damper systems in them that are supposed to allow for the emissions to escape, but you don't want to lose heat, so many arenas close the dampers," Johnson said.

Toronto's green fleet totals about 368 vehicles, including hybrid gas-electric cars and pickup trucks, but not counting transit vehicles.

Nova Scotia Power says it now generates 30 per cent of its power from renewables

Nova Scotia Power Renewable Energy delivers 30% in 2018, led by wind power, hydroelectric and biomass, with coal and natural gas declining, as Muskrat Falls imports from Labrador target 40% renewables to cut emissions.

 

Key Points

It is the utility's 30% 2018 renewable mix and plan to reach 40% via Muskrat Falls while reducing carbon emissions.

✅ 18% wind, 9% hydro and tidal, 3% biomass in 2018

✅ Coal reliance fell from 76% in 2007 to 52% in 2018

✅ 58% carbon emissions cut from 2005 levels projected by 2030

 

Nova Scotia's private utility says it has hit a new milestone in its delivery of electricity from renewable resources, a trend highlighted by Summerside wind generation in nearby P.E.I.

Nova Scotia Power says 30 per cent of the electricity it produced in 2018 came from renewable sources such as wind power.

The utility says 18 per cent came from wind turbines, nine per cent from hydroelectric and tidal turbines and three per cent by burning biomass.

However, over half of the province's electrical generation still comes from the burning of coal or petroleum coke. Another 13 per cent come from burning natural gas and five per cent from imports, even as U.S. renewable generation hits record shares.

The utility says that since 2007, the province's reliance on coal-fired plants has dropped from 76 per cent of electricity generated to 52 per cent last year, as Prairie renewables growth accelerates nationally.

It says it expects to meet the province's legislated renewable target of 40 per cent in 2020, when it begins accessing hydroelectricity from the Muskrat Falls project in Labrador.

"We have made greener, cleaner energy a priority," utility president and CEO Karen Hutt said in a news release.

"As we continue to achieve new records in renewable electricity, we remain focused on ensuring electricity prices stay predictable and affordable for our customers, including solar customers across the province."

Nova Scotia Power also projects achieving a 58 per cent reduction in carbon emissions from 2005 levels by 2030.

More Polar Vortex 2021 Fallout (and Texas Two-Step): Monitor For ERCOT Identifies Improper Payments For Ancillary Services

ERCOT Ancillary Services Clawback and VOLL Pricing summarize PUCT and IMM actions on load shed, real-time pricing adders, clawbacks, and settlement corrections after the 2021 winter storm in the Texas power grid market.

 

Key Points

Policies addressing clawbacks for unprovided AS and correcting VOLL-based price adders after load shed ended in ERCOT.

✅ PUCT ordered clawbacks for ancillary services not delivered.

✅ IMM urged price correction after firm load shed ceased.

✅ ERCOT's VOLL adder raised costs by $16B during 32 hours.

 

Potomac Economics, the Independent Market Monitor (IMM) for the Electric Reliability Council of Texas (ERCOT), filed a report with the Public Utility Commission of Texas (PUCT) that certain payments were made by ERCOT for Ancillary Services (AS) that were not provided, even as ERCOT later issued a winter reliability RFP to procure capacity during subsequent seasons.

According to the IMM (emphasis added):

There were a number of instances during the operating days outlined above in which AS was not provided in real time because of forced outages or derations. For market participants that are not able to meet their AS responsibility, typically the ERCOT operator marks the short amount in the software. This causes the AS responsibility to be effectively removed and the day-ahead AS payment to be clawed back in settlement. However, the ERCOT operators did not complete this task during the winter event, echoing issues like the Ontario IESO phantom demand that cost customers millions, and therefore the "failure to provide" settlements were not invoked in real time.

Removing the operator intervention step and automating the "failure to provide" settlement was contemplated in NPRR947: Clarification to Ancillary Service Supply Responsibility Definition and Improvements to Determining and Charging for Ancillary Service Failed Quantities; however, the NPRR was withdrawn in August 2020 amid ongoing market reform discussions because of the system cost, some complexities related to AS trades, and the implementation of real-time co-optimization.

Invoking the "failure to provide" settlement for all AS that market participants failed to provide during the operating days outlined above will produce market outcomes and settlements consistent with underlying market principles. In this case, the principle is that market participants should not be paid for services that they do not provide, even as a separate ruling found power plants exempt from providing electricity in emergencies under Texas law, underscoring the distinction between obligations and settlements. Whether ERCOT marked the short amount in real-time or not should not affect the settlement of these ancillary services.

On March 3, 2021, the PUCT ordered (a related press release is here) that:

ERCOT shall claw back all payments for ancillary service that were made to an entity that did not provide its required ancillary service during real time on ERCOT operating days starting February 14, 2021 and ending on February 19,2021.

On March 4, 2021, the IMM filed another report and recommended that:

the [PUCT] direct ERCOT to correct the real-time prices from 0:00 February 18,2021, to 09:00 February 19, 2021, to remove the inappropriate pricing intervention that occurred during that time period.

The IMM approvingly noted the PUCT's February 15, 2021 order, which mandated that real-time energy prices reflect firm load shed by setting prices at the value of lost load (VOLL).1

According to the IMM (emphasis added):

This is essential in an energy-only market, like ERCOT's, where the Texas power grid faces recurring crisis risks, because it provides efficient economic signals to increase the electric generation needed to restore the load and service it reliably over the long term.

Conversely, it is equally important that prices not reflect VOLL when the system is not in shortage and load is being served, and experiences in capacity markets show auction payouts can fall sharply under different conditions. The Commission recognized this principle in its Order, expressly stating it is only ERCOT's out-of-market shedding firm load that is required to be reflected in prices. Unfortunately, ERCOT exceeded the mandate of the Commission by continuing to set process at VOLL long after it ceased the firm load shed.

ERCOT recalled the last of the firm load shed instructions at 23:55 on February 17, 2021. Therefore, in order to comply with the Commission Order, the pricing intervention that raised prices to VOLL should have ended immediately at that time. However, ERCOT continued to hold prices at VOLL by inflating the Real-Time On-Line Reliability Deployment Price Adder for an additional 32 hours through the morning of February 19. This decision resulted in $16 billion in additional costs to ERCOT's market, prompting legislative bailout proposals in Austin, of which roughly $1.5 billion was uplifted to load-serving entities to provide make-whole payments to generators for energy that was not needed or produced.

However, at its March 5, 2021, open meeting (related discussion begins around minute 20), although the PUCT acknowledged the "good points" raised by the IMM, the PUCT was not willing to retrospectively adjust its real-time pricing for this period out of concerns that some related transactions (ICE futures and others) may have already settled and for unintended consequences of such retroactive adjustments.

A New Era for Churchill Falls: Newfoundland and Labrador Secures Billions in Landmark Deal with Quebec

Churchill Falls NL-Quebec Agreement boosts hydropower revenues, revises power purchase pricing, expands transmission lines, and integrates Indigenous rights, enabling renewable energy growth, domestic supply, exports, and interprovincial collaboration on infrastructure and utility modernization.

 

Key Points

A renegotiated hydropower deal reallocating power and advancing projects with Indigenous benefits in NL and Quebec.

✅ Raises Hydro-Quebec price for Churchill Falls electricity

✅ Increases NL power share for domestic use and exports

✅ Commits joint projects and Indigenous participation safeguards

 

St. John's, Newfoundland and Labrador - In a historic development, Newfoundland and Labrador (NL) and Quebec have reached a tentative agreement over the controversial Churchill Falls hydroelectric project, amid Quebec's electricity ambitions and longstanding regional sensitivities, potentially unlocking hundreds of billions of dollars for the Atlantic province. The deal, announced jointly by Premier Andrew Furey and Quebec Premier François Legault, aims to rectify the decades-long imbalance in the original 1969 contract, which saw NL receive significantly less revenue than Quebec for the province's vast hydropower resources.

The core of the new agreement involves a substantial increase in the price that Hydro-Québec pays for electricity generated at Churchill Falls. This price hike, retroactive to January 1, 2025, is expected to generate billions in additional revenue for NL over the next several decades. The deal also includes provisions for:

  • Increased power allocation for NL: The province will gain a larger share of the electricity generated at Churchill Falls, allowing for increased domestic consumption and potential export opportunities through the sale and trade of power across regional markets.
  • Joint infrastructure development: Both provinces will collaborate on new energy projects, in line with Hydro-Québec's $185-billion plan to reduce fossil fuel reliance, including potential expansions to the Churchill Falls generating station and the development of new transmission lines.
  • Indigenous involvement: The agreement acknowledges the importance of Indigenous rights and seeks to ensure that Indigenous communities in both provinces benefit from the project.

This landmark deal represents a significant victory for NL, which has long argued that the original 1969 contract was grossly unfair. The province has been seeking to renegotiate the terms of the agreement for decades, citing the low price paid for electricity and the significant economic benefits that have accrued to Quebec.

Key Implications:

  • Economic Transformation: The influx of revenue from the new Churchill Falls agreement has the potential to significantly transform the economy of NL, though the legacy of Muskrat Falls costs tempers expectations before plans are finalized. The province can invest in critical infrastructure projects, such as healthcare, education, and transportation, as well as support economic diversification initiatives.
  • Energy Independence: The increased access to electricity will enhance NL's energy security and reduce its reliance on fossil fuels. This shift towards renewable energy aligns with the province's climate change goals, and in the context of Quebec's no-nuclear stance could attract new investment in sustainable industries.
  • Interprovincial Relations: The successful negotiation of this complex agreement demonstrates the potential for constructive collaboration between provinces on major infrastructure projects, as seen in recent NB Power-Hydro-Québec agreements to import more electricity. It sets a precedent for future interprovincial partnerships on issues of shared interest.

Challenges and Considerations:

  • Implementation: The successful implementation of the agreement will require careful planning and coordination between the two provinces.
  • Environmental Impact: The expansion of hydroelectric generation at Churchill Falls must be carefully assessed for its potential environmental impacts, including the effects on local ecosystems and Indigenous communities.
  • Public Consultation: It is crucial that the governments of NL and Quebec engage in meaningful public consultation throughout the implementation process to ensure that the benefits of the agreement are shared equitably across both provinces.

The Churchill Falls agreement marks a turning point in the history of energy development in Canada. It demonstrates the potential for provinces to work together to achieve mutually beneficial outcomes, even as Nova Scotia shifts toward wind and solar after stepping back from the Atlantic Loop, while also addressing historical inequities and ensuring a more equitable distribution of the benefits of natural resources.

Covid-19 puts brake on Turkey’s solar sector

Turkey Net Metering Suspension freezes regulator reviews, stalling rooftop solar permits and grid interconnections amid COVID-19, pausing licensing workflows, EPC pipelines, and electricity bill credits that drive commercial and household prosumer adoption.

 

Key Points

A pause on technical reviews freezing net metering applications and slowing rooftop solar deployment in Turkey.

✅ Monthly technical committee meetings suspended indefinitely

✅ Rooftop solar permits and grid interconnections on hold

✅ EPC firms urge remote evaluations for transparency

 

The decision by the Turkish Energy Market Regulatory Authority to halt part of the system of processing net metering applications risks bringing the only vibrant segment of the nation’s solar industry to a grinding halt, a risk amplified as global renewables face Covid-19 disruptions across markets.

The regulator has suspended monthly meetings of the committee which makes technical evaluations of net metering applications, citing concerns about the spread of Covid-19, which has already seen U.S. utility-scale solar face delays this year.

The availability of electricity bill credits for net-metering-approved households which inject surplus power into the grid, similar to how British households can sell power back to energy firms, has seen the rooftop projects the scheme is typically associated with remain the only source of new solar generation capacity in Turkey of late.

However the energy regulator’s decision to suspend technical evaluation committee meetings until further notice has seen the largely online licensing process for new solar systems practically cease; by contrast, Berlin is being urged to remove PV barriers to keep projects moving.

The Turkish solar industry has claimed the move is unnecessary, with solar engineering, procurement and construction services businesses pointing out the committee could meet to evaluate projects remotely. It has been argued such a move would streamline the application process and make it more transparent, regardless of the current public health crisis.

 

Net metering 

Turkey introduced net metering for rooftop installations last May and pv magazine has reported the specifics of the scheme, amid debates like New England's grid upgrade costs over who pays.

National grid operator Teias confirmed recently the country added 109 MW of new solar capacity in the first quarter, most of it net-metered rooftop systems, even as Australian distributors warn excess solar can strain local networks.

Net metering has been particularly attractive to commercial electricity users because the owners of small and medium-sized businesses pay more for power, as solar reshapes electricity prices in Northern Europe, than either households or large scale industrial consumers.

Until the recent technical committee decision by the regulator, the chief obstacle to net metering adoption had been the nation’s economic travails. The Turkish lira has lost 14% of its value since January and around 36% over the last two years. The central bank has been using its foreign reserves to support state lenders and the lira but the national currency slipped near an all-time low on Friday and foreign analysts predict the central bank reserves could run dry in July.

The level of exports shipped last month was down 41% on April last year and imports fell 28% by the same comparison, further depressing the willingness of companies to make capital investments such as rooftop solar.

Sens. Wyden, Merkley Introduce Bill to Ensure More Wildfire Resilient Power Grid

Wildfire Resilient Power Grid Act proposes DOE grants for utility companies to fund wildfire mitigation, grid resilience upgrades, undergrounding power lines, fast-tripping protection, weather monitoring, and vegetation management, prioritizing rural electric cooperatives.

 

Key Points

A federal bill funding utility wildfire mitigation and grid hardening via DOE grants, prioritizing rural utilities.

✅ $1B DOE matching grants for grid upgrades and wildfire mitigation.

✅ Prioritizes rural utilities; supports undergrounding and hardening.

✅ Funds fast-tripping protection, weather stations, vegetation management.

 

U.S. Sens. Ron Wyden and Jeff Merkley today introduced new legislation, amid transmission barriers that persist, to incentivize utility companies to do more to reduce wildfire risks as aging power infrastructure ignite wildfires in Oregon and across the West.

Wyden and Merkley's Wildfire Resilient Power Grid Act of 2020 would ensure power companies do their part to reduce the risk of wildfires through power system upgrades, even as California utility spending crackdown seeks accountability, such as the undergrounding of power lines, fire safety equipment installation and proper vegetation management.

"First and foremost, this is a public safety issue. Fire after fire ignited this summer because the aging power grid could not withstand a major windstorm during the season's hottest and driest days," Wyden said. "Many utility companies are already working to improve the resiliency of their power grid, but the sheer costs of these investments must not come at the expense of equitable regulation for rural utility customers. Congress must do all that it can to stop the catastrophic wildfires decimating the West, and that means improving rural infrastructure. By partnering with utilities around the country, we can increase wildfire mitigation efforts at a modest cost -- a fire prevention investment that will pay dividends by saving lives, homes and businesses."

"When this year's unprecedented wildfire event hit, I drove hundreds of miles across our state to see the damage firsthand and to hear directly from impacted communities, so that I could go back to D.C. and work for the solutions they need," said Merkley. "What I saw was apocalyptic--and we have to do everything we can to reduce the risk of this happening again. That means we have to work with our power companies to get critical upgrades and safety investments into place as quickly as possible."

The Wildfire Resilient Power Grid Act of 2020:

* Establishes a $1 billion-per-year matching grant program for power companies through the Department of Energy, even as ACORE opposed DOE subsidy proposals, to reduce the risk of power lines and grid infrastructure causing wildfires.

* Gives special priority to smaller, rural electric companies to ensure mitigation efforts are targeted to forested rural areas.

* Promotes proven methods for reducing wildfire risks, including undergrounding of lines, installing fast-tripping protection systems, and constructing weather monitoring stations to respond to electrical system fire risks.

* Provides for hardening of overhead power lines and installation of fault location equipment where undergrounding of power lines is not a favorable option.

* Ensures fuels management activities of power companies are carried out in accordance with Federal, State, and local laws and regulations.

* Requires power companies to have "skin in the game" by making the program a 1-to-1 matching grant, with an exception for smaller utilities where the matching requirement is one third of the grant.

* Delivers accountability on the part of utilities and the Department of Energy by generating a report every two years on efforts conducted under the grant program.

Portland General Electric President and CEO Maria Pope: "We appreciate Senator Wyden's and Senator Merkley's leadership in proposing legislation to provide federal funding that will help protect Oregon from devastating wildfires. When passed, this will help make Oregon's electric system safer, faster, without increasing customer prices. That is especially important given the economy and hotter, drier summers and longer wildfire seasons that Oregon will continue to face."

Lane County Commission Chair Heather Butch: " In a matter of hours, the entire Lane County community of Blue River was reduced to ashes by the Holiday Farm Fire. Since the moment I first toured that devastation I've been committed to building it back better. I applaud Senators Wyden and Merkley for drafting the Wildfire Resilient Power Grid Act, as it could well provide the path towards meeting this important goal. Moreover, the resultant programs will better protect rural communities from the increasing dangers of wildfires through a number of preventative measures that would otherwise be difficult to implement."

Linn County Commissioner Roger Nyquist: "This legislation is a smart strategic investment for the future safety of our residents as well as the economic vitality of our community."

Marion County Commissioner Kevin Cameron: "After experiencing a traumatic evacuation during the Beachie Creek and Lion's Head wild fires, I understand the need to strengthen the utility Infrastructure. The improvements resulting from Senator Wyden and Merkley's bill will reduce disasters in the future, but improve everyday reliability for our citizens who live, work and protect the environment in potential wildfire areas."

Edison Electric Institute President Tom Kuhn: "EEI thanks Senator Wyden and Senator Merkley for their leadership in introducing the Wildfire Resilient Power Grid Act. This bill will help support and accelerate projects already planned and underway to enhance energy grid resiliency and mitigate the risk of wildfire damage to power lines. Electric companies across the country are committed to working with our government partners and other stakeholders on preparation and mitigation efforts that combat the wildfire threat and on the rapid deployment of technology solutions, including aggregated DERs at FERC, that address wildfire risks, while still maintaining the safe, reliable, and affordable energy we all need."

Oregon Rural Electric Cooperative Association Executive Director Ted Case: "Oregon's electric cooperatives support the Wildfire Resilient Power Grid Act and appreciate Senator Wyden's and Senator Merkley's leadership and innovative approach to wildfire mitigation, particularly for small, rural utilities. This legislation includes targeted assistance that will help us to continue to provide affordable, reliable and safe electricity to over 500,000 Oregonians."

Sustainable Northwest Director of Government Affairs & Program Strategy Dylan Kruse: "In recent years, the West has seen too many wildfires originate due to poorly maintained or damaged electric utility transmission and distribution infrastructure. This legislation plays an important role to ensure that power lines do not contribute to wildfire starts, while providing safe and reliable power to communities during wildfire events. Utilities must, even as Wyoming clean energy bill proposals emerge, live up to their legal requirements to maintain their infrastructure, but this bill provides welcome resources to expedite and prioritize risk reduction, while preventing cost increases for ratepayers."

Oregon Wild Wilderness Program Manager Erik Fernandez: "2020 taught Oregon the lesson that California learned in the Paradise Fire, and SCE wildfire lawsuits that followed underscore the stakes. Addressing the risk of unnaturally caused powerline fires is an increasingly important critical task. I appreciate Senator Ron Wyden's efforts to protect our homes and communities from powerline fires."

Sustainable Marine now delivering electricity to Nova Scotia grid from tidal energy

Sustainable Marine tidal energy delivers in-stream power to Nova Scotia's grid from Grand Passage, proving low-impact, renewable generation and advancing a floating tidal array at FORCE and Minas Passage in the Bay of Fundy.

 

Key Points

The first in-stream tidal project supplying clean power to Nova Scotia's grid, proven at Grand Passage.

✅ First to deliver in-stream tidal power to Canada's grid

✅ Demonstration at Grand Passage informs FORCE deployments

✅ Low-impact design and environmental monitoring validated

 

Sustainable Marine has officially powered up its tidal energy operation in Canada and is delivering clean electricity to the power system in Nova Scotia, on the country’s Atlantic coast, as the province moves to increase wind and solar projects in the years ahead. The company’s system in Grand Passage is the first to deliver in-stream tidal power to the grid in Canada, following provincial approval to harness Bay of Fundy tides that is spurring further development.

The system start-up is the culmination of more than a decade of research, development and testing, including lessons from Scottish tidal projects in recent years and a powerful tidal turbine feeding onshore grids, managing the technical challenges associated with operating in highly energetic environments and proving the ultra-low environmental impact of the tidal technology.

Sustainable Marine is striving to deliver the world’s first floating tidal array at FORCE (Fundy Ocean Research Centre for Energy). This project will be delivered in phases, drawing upon the knowledge gained and lessons learned in Grand Passage, and insights from offshore wind pilots like France’s first offshore wind turbine in Europe. In the coming months the company will continue to operate the platform at its demonstration site at Grand Passage, gradually building up power production, while New York and New England clean energy demand continues to rise, to further prove the technology and environmental monitoring systems, before commencing deployments in the Minas Passage – renowned as the Everest of tidal energy.

The Bay of Fundy’s huge tidal energy resource contains more than four times the combined flow of every freshwater river in the world, with the potential to generate approximately 2,500 MW of green energy, underscoring why independent electricity planning will be important for integrating marine renewables.
