The Green Grid expands global community

TransAlta Renewables US wind farms achieved commercial operation, adding 119 MW of wind energy capacity in Pennsylvania and New Hampshire, backed by PPAs with Microsoft, Partners Healthcare, and NHEC, and supported by tax equity financing.

Key Points

Two US wind projects totaling 119 MW, now online under PPAs and supported by tax equity financing.

✅ 119 MW online in Pennsylvania and New Hampshire

✅ PPAs with Microsoft, Partners Healthcare, and NHEC

✅ About USD 126 million raised via tax equity

TransAlta Renewables Inc says two US wind farms, with a total capacity of 119 MW and operated by its parent TransAlta Corp, became operational in December, amid broader build-outs such as Enel's 450-MW U.S. project coming online and, in Canada, Acciona's 280-MW Alberta wind farm advancing as well.

The 90-MW Big Level wind park in Pennsylvania started commercial operation on December 19. It sells power to technology giant Microsoft Corporation under a 15-year contract, reflecting big-tech procurement alongside Amazon's clean energy projects in multiple markets.

The 29-MW Antrim wind facility in New Hampshire is operational since December 24. It is selling power under 20-year contracts with Boston-based non-profit hospital and physicians network Partners Healthcare and New Hampshire Electric Co-op, mirroring East Coast activity at Amazon Wind Farm US East now fully operational.

The Canadian renewable power producer, which has economic interest in the two wind parks, said that upon their reaching commercial operations, it raised about USD 126 million (EUR 113m) of tax equity to partially fund the projects, as mega-deployments like Invenergy and GE's record North American project and capital plans such as a $200 million Alberta build by a Buffett-linked company underscore financing momentum.

"We continue to pursue additional growth opportunities, including potential drop-down transactions with TransAlta Corp," TransAlta Renewables president John Kousinioris commented.

The comment comes as TransAlta scrapped an Alberta wind project amid Alberta policy shifts.

California Heat Wave Grid Emergency sees CAISO issue Stage 3 alerts as record demand, extreme heat, and climate change strain renewable energy; conservation efforts avert rolling blackouts and protect grid reliability statewide.

Key Points

A grid emergency in California's heat wave, with CAISO Stage 3 alerts amid record demand and risk of rolling blackouts.

✅ CAISO triggered Stage 3 alerts, then downgraded by 8 pm PT

✅ Record 52,061 MW demand; conservation reduced grid stress

✅ Extreme heat and climate change heightened outage risks

California has avoided ordering rolling blackouts after electricity demand reached a record-high Tuesday night from excessive heat across the state, even as energy experts warn the U.S. grid faces mounting climate stresses. 

The California Independent System Operator, which oversees the state’s electrical grid, imposed its highest level energy emergency on Tuesday, a step that comes before ordering rolling blackouts and allows the state to access emergency power sources.

The Office of Emergency Services also sent a text alert to residents requesting them to conserve power. The operator downgraded the Stage 3 alert around 8:00 p.m. PT on Tuesday and said that “consumer conservation played a big part in protecting electric grid reliability,” and in bolstering grid resilience overall.

The state capital of Sacramento reached 116 degrees Fahrenheit on Tuesday, according to the National Weather Service, surpassing a record that was set almost 100 years ago. And nearly a half-dozen cities in the San Francisco Bay Area tied or set all-time highs, the agency said.

CAISO said peak power demand on Tuesday reached 52,061 megawatts, surpassing a previous high of 50,270 megawatts on July 24, 2006, while nearby B.C. electricity demand has also hit records during extreme weather.

While the operator did not order rolling blackouts, three Northern California cities saw brief power outages, and severe storms have caused similar disruptions statewide in recent months. As of 7:00 am PT on Wednesday, nearly 8,000 customers in California were without power, according to PowerOutage.us. 

Gov. Gavin Newsom, in a Twitter video on Tuesday, warned the temperatures across California were unprecedented and the state is headed into the worst part of the heat wave, which is on track to be the hottest and longest on record for September.

“The risk for outages is real and it’s immediate,” Newsom said. “These triple-digit temperatures throughout much of the state are leading, not surprisingly, to record demand on the energy grid.”

The governor urged residents to pre-cool their homes earlier in the day when more power is available and turn thermostats to 78 degrees or higher after 4:00 pm PT. “Everyone has to do their part to help step up for just a few more days,” Newsom said.

The possibility for widespread outages reflects how power grids in California and other states are becoming more vulnerable to climate-related disasters such as heat waves, storms and wildfires across California.

California, which has set a goal to transition to 100% carbon-free electricity by 2045, has shuttered a slew of gas power plants in the past few years, leaving the state increasingly dependent on solar energy.

At times, the state has produced a clean energy surplus during peak solar generation, underscoring the challenges of balancing supply and demand.

The megadrought in the American West has generated the driest two decades in the region in at least 1,200 years, and human-caused climate change has fueled the problem, scientists said earlier this year. Conditions will likely continue through 2022 and persist for years.

California Storm Outages and Landslides strain utilities, trigger flooding, road closures, and debris flows, causing widespread power cuts and infrastructure damage as emergency response teams race to restore service, clear slides, and support evacuations.

Key Points

California Storm Outages and Landslides are storm-driven power cuts and slope failures disrupting roads and utilities.

✅ Tens of thousands face prolonged power outages across regions

✅ Landslides block highways, damage property, hinder access

✅ Crews restore grids, clear debris, support shelters and evacuees

California is grappling with a dual crisis of power outages and landslides following a severe storm that has swept across the state. The latest reports indicate widespread disruptions affecting thousands of residents and significant infrastructure damage. This storm is not only a test of California's emergency response capabilities but also a stark reminder of the increasing vulnerability of the state to extreme weather events, and of the U.S. electric grid in the face of climate stressors.

Storm’s Impact on California

The recent storm, which hit California with unprecedented intensity, has unleashed torrential rain, strong winds, and widespread flooding. These severe weather conditions have overwhelmed the state’s infrastructure, leading to significant power outages that are affecting numerous communities. According to local utilities, tens of thousands of homes and businesses are currently without electricity. The outages have been exacerbated by the combination of heavy rain and gusty winds, which have downed power lines and damaged electrical equipment.

In addition to the power disruptions, the storm has triggered a series of landslides across various regions. The combination of saturated soil and intense rainfall has caused several hillside slopes to give way, leading to road closures and property damage. Emergency services are working around the clock to address the aftermath of these landslides, but access to affected areas remains challenging due to blocked roads and ongoing hazardous conditions.

Emergency Response and Challenges

California’s emergency response teams are on high alert as they coordinate efforts to manage the fallout from the storm. Utility companies are deploying repair crews to restore power as quickly as possible, but the extensive damage to infrastructure means that some areas may be without electricity for several days. The state’s Department of Transportation is also engaged in clearing debris from landslides and repairing damaged roads to ensure that emergency services can reach affected communities.

The response efforts are complicated by the scale of the storm’s impact. With many areas experiencing both power outages and landslides, the logistical challenges are immense. Emergency shelters have been set up to provide temporary refuge for those displaced by the storm, but the capacity is limited, and there are concerns about overcrowding and resource shortages.

Community and Environmental Implications

The storm’s impact on local communities has been profound. Residents are facing not only the immediate challenges of power outages and unsafe road conditions but also longer-term concerns about recovery and rebuilding. Many individuals have been forced to evacuate their homes, and local businesses are struggling to cope with the disruption.

Environmental implications are also significant. The landslides and flooding have caused considerable damage to natural habitats and have raised concerns about water contamination and soil erosion. The impact on the environment could have longer-term consequences for the state’s ecosystems and water supply.

Climate Change and Extreme Weather

This storm underscores a growing concern about the increasing frequency and intensity of extreme weather events linked to climate change. California has been experiencing a rise in severe weather patterns, including intense storms, prolonged droughts, and extreme heat waves that strain the grid. These changes are putting additional strain on the state’s infrastructure and emergency response systems.

Experts have pointed out that while individual storms cannot be directly attributed to climate change, the overall trend towards more extreme weather is consistent with scientific predictions. As such, there is a pressing need for California to invest in infrastructure improvements and resilience measures, and to consider accelerating its carbon-free electricity mandate to better withstand future events.

Looking Ahead

As California deals with the immediate aftermath of this storm, attention will turn to recovery and rebuilding efforts. The state will need to address the damage caused by power outages and landslides while also preparing for future challenges posed by climate change.

In the coming days, the focus will be on restoring power, clearing debris, and providing support to affected communities. Long-term efforts will likely involve reassessing infrastructure vulnerabilities, improving emergency response protocols, and investing in climate resilience measures across the grid.

Irving Oil hydrogen electrolyzer expands green hydrogen capacity at the Saint John refinery with Plug Power technology, cutting carbon emissions, enabling clean fuel for buses, and supporting Atlantic Canada decarbonization and renewable grid integration.

Key Points

A 5 MW Plug Power unit at Irving's Saint John refinery producing low-carbon hydrogen via electrolysis.

✅ Produces 2 tonnes/day, enough to fuel about 60 hydrogen buses

✅ Uses grid power; targets cleaner supply via renewables and nuclear

✅ First Canadian refinery investing in electrolyzer technology

Irving Oil is expanding hydrogen capacity at its Saint John, N.B., refinery in a bid to lower carbon emissions and offer clean energy to customers.

The family-owned company said Tuesday it has a deal with New York-based Plug Power Inc. to buy a five-megawatt hydrogen electrolyzer that will produce two tonnes of hydrogen a day — equivalent to fuelling 60 buses with hydrogen — using electricity from the local grid and drawing on examples such as reduced electricity rates proposed in Ontario to grow the hydrogen economy.

Hydrogen is an important part of the refining process as it's used to lower the sulphur content of petroleum products like diesel fuel, but most refineries produce hydrogen using natural gas, which creates carbon dioxide emissions and raises questions explored in hydrogen's future for power companies in the energy sector.

"Investing in a hydrogen electrolyzer allows us to produce hydrogen in a very different way," Irving director of energy transition Andy Carson said in an interview.

"Instead of using natural gas, we're actually using water molecules and electricity through the electrolysis process to produce ... a clean hydrogen."

Irving plans to continue to work with others in the province to decarbonize the grid amid pressures like Ontario's push into energy storage as electricity supply tightens and ensure the electricity being used to power its hydrogen electrolyzer is as clean as possible, he said.

N.B. Power's electrical system includes 14 generating stations powered by hydro, coal, oil, wind, nuclear and diesel. The utility has committed to increasing its renewable energy sources and exploring innovations such as EV-to-grid integration piloted in Nova Scotia.

Irving said it will be the first oil refinery in Canada to invest in electrolyzer technology, as Ontario's Hydrogen Innovation Fund supports broader deployment nationwide.

The company said its goal is to offer hydrogen fuelling infrastructure in Atlantic Canada, complementing N.L.'s fast-charging network for EV drivers in the region.

"This kind of investment allows us to not just move to a cleaner form of hydrogen in the refinery. It also allows us to store and make hydrogen available to the marketplace," Carson said.

Federal watchdog warns Canada's 2030 emissions target may not be achievable
The hydrogen technology will help Irving "unlock pent up demand for hydrogen as an energy transition fuel for logistics organizations," he said.

Alberta also aims to expand its hydrogen production over the coming years, alongside British Columbia's $900 million hydrogen project moving ahead on the West Coast. 

Those plans lean on the development of carbon capture and storage (CCS) technology that aims to trap the emissions created when producing hydrogen from natural gas.

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.

Birtle Transmission Line connects Manitoba Hydro to SaskPower, enabling 215 MW of clean hydroelectricity, improving grid reliability, supporting affordable rates, and advancing Green Infrastructure goals under the Investing in Canada Plan across Manitoba and Saskatchewan.

Key Points

A 46 km line moving up to 215 MW from Manitoba Hydro to SaskPower, improving reliability and supplying cleaner power.

✅ Enables interprovincial grid tie between Manitoba and Saskatchewan

✅ Delivers up to 215 MW of renewable hydroelectricity

✅ Supports affordable rates and lower GHG emissions

The federal government announced funding for the Birtle Transmission Line Monday morning.

The project will help Manitoba Hydro build a transmission line from Birtle South Station in the Municipality of Prairie View to the Manitoba–Saskatchewan border 46 kilometres northwest. Once completed, the new line will allow up to 215 megawatts of hydroelectricity to flow from the Manitoba Hydro power grid to the SaskPower power grid, similar to the Great Northern Transmission Line connecting Manitoba and Minnesota today.

The government said the transmission line would create a more stable energy supply, keep energy rates affordable and help Saskatchewan's efforts to reduce cumulative greenhouse-gas emissions in that province.

"The Government of Canada is proud to be working with Manitoba to support projects that create jobs and improve people's lives across the province. The Birtle Transmission Line will provide the region with reliable and greener energy, as seen with Canadian hydropower to New York projects, that will help protect our environment while laying the groundwork for clean economic growth," said Jim Carr, member of Parliament for Winnipeg South Centre, on behalf of Catherine McKenna, minister of infrastructure and communities.

The Government of Canada is investing more than $18.7 million, and the government of Manitoba is contributing more than $42 million in this project through the Green Infrastructure Stream of the Investing in Canada Plan, which also supports Atlantic grid improvements nationwide.

"The Province of Manitoba has one of the cleanest electricity grids in Canada and the world with over 99 per cent of our electricity generated from clean, renewable sources, rooted in Manitoba's hydro history," said Central Services Minister Reg Helwer. "The Made-in-Manitoba Climate and Green Plan is good not only for Manitoba but for Canada and globally."

Jay Grewal, president, and CEO of Manitoba Hydro said the funding is a great example of co-operation between the provincial and federal governments, including investments in smart grid technology that modernize local networks.

"We are very pleased that Manitoba Hydro's Birtle Transmission Project is among the first projects to receive funding under the Canada Infrastructure Program, and we would like to thank both levels of governments for recognizing the importance of the project as we strengthen ties with our neighbours in Saskatchewan, as U.S.-Canada transmission approvals advance elsewhere," said Grewal.

A spokesperson for Manitoba Hydro said it’s too early to say how many jobs will be created during construction, as final contracts have not yet been awarded.
