BC Hydro crews spent Thanksgiving Monday pouring over computer data to try and locate the cause of a massive power outage that darkened homes from Ladysmith to Victoria on Vancouver Island the previous day — but so far they've found no answers.

All they've been able to determine is that it's not an obvious problem, said BC Hydro spokesman Ted Olynyk.

"It's not like a tree fell on the line, or it was wind or snow or ice or there was physical damage to the property," explained Olynyk.

"What we are doing now is BC Transmission Corp. technical folks are reviewing computer information, data, to see if they can pinpoint where and when the fault happened."

The outage began with disruption of at least one south Island power line around 5:45 p.m. local time October 12. A cascade effect amplified the damage by subsequently tripping all the power lines south of Ladysmith, including the Gulf Islands, and leaving more than 200,000 customers in the dark during Thanksgiving dinner.

That's not supposed to happen, said Olynyk. The Island's power system, which includes 31 substations, was built to protect against cascade outages when a few lines go down, he said.

"It's designed so that doesn't happen," said Olynyk. Nonetheless, it has happened in the past, most often when lightening strikes, he said.

What caused the cascade is now a primary focus of the investigation, said Olynyk.

"It's very important to find the reasons for this, so we can take preventive measures and ensure this doesn't happen again, not only at the location it will have happened but throughout the power system."

When the power failed, BC Hydro crews were quick to try and visually inspect as many of the transmission lines as they could, said Olynyk.

Finding no obvious problems — cut cables, fallen trees or blown transformers, for example — they began activating lines one by one to see if they would hold power, said Olynyk. They did, and all were re-activated by 8 p.m.

It's similar, he said, to tripping a circuit breaker in a house. Sometimes the combination of appliances that trigger the outage is not clear, but power can be restored by resetting the breaker at the source.

"Sometimes we've gone out there and there's an outage and there's no indication of what caused the outage," he said. "We reset the system and it's back up, and sometimes we just don't know."

Calgary's electricity use soars in frigid February, Enmax says

Calgary Winter Energy Usage Surge highlights soaring electricity demand, added megawatt-hours, and grid reliability challenges driven by extreme cold, heating loads, and climate change, with summer air conditioning also shifting seasonal peaks.

 

Key Points

A spike in Calgary's power use from extreme cold, adding 22k MWh and testing reliability as heating demand rises.

✅ +22,000 MWh vs Feb 2018 amid fourth-coldest February

✅ Heating loads spike; summer A/C now drives peak demand

✅ Grid reliability monitored; more solar and green resources ahead

 

February was so cold in Calgary that the city used enough extra energy to power 3,400 homes for a whole year, echoing record-breaking demand in B.C. in 2021 during severe cold.

Enmax Power Corporation, the primary electricity utility in the city, says the city 's energy consumption was up 22,000 megawatt hours last month compared with Februray 2018.

"We've seen through this cold period our system has held up very well. It's been very reliable," Enmax vice-president Andre van Dijk told the Calgary Eyeopener on Friday. "You know, in the absence of a windstorm combined with cold temperatures and that sort of thing, the system has actually held up pretty well."

The past month was the fourth coldest in Calgary's history, and similar conditions have pushed all-time high demand in B.C. in recent years across the West. The average temperature for last month was –18.1 C. The long-term average for February is –5.4 C.

 

Watching use, predicting issues

The electricity company monitors demand and load on a daily basis, always trying to predict issues before they happen, van Dijk said, and utilities have introduced winter payment plans to help customers manage bills during prolonged cold.

One of the issues they're watching is climate change, and how extreme temperatures and weather affect both the grid's reliability, as seen when Quebec shattered consumption records during cold snaps, and the public's energy use.

The colder it gets, the higher you turn up the heat. The hotter it is, the more you use air conditioning.

He also noted that using fuels then contributes to climate change, creating a cycle.

​"We are seeing variations in temperature and we've seen large weather events across the continent, across the world, in fact, that impact electrical systems, whether that's flooding, as we've experienced here, or high winds, tornadoes," van Dijk said.

"Climate change and changing weather patterns have definitely had had an impact on us as an electrical industry."

In 2012, he said, Calgary switched from using the most power during winter to using the most during summer, in large part due to air conditioning, he said.

"Temperature is a strong influencer of energy consumption and of our demand," van Dijk said.

Christmas tree lights have also become primarily LED, van Dijk said, which cuts down on a big energy draw in the winter.

He said he expects more solar and other green resources will be added into the electrical system in the future to mitigate how much the increasingly levels of energy use impact climate change, and to help moderate electricity costs in Alberta over time.

UK National Grid Commissions 2GW Substation

UK 2-GW Substation strengthens National Grid power transmission in Kent, enabling offshore wind integration, voltage regulation, and grid modernization to meet rising electricity demand and support the UK energy transition with resilient, reliable infrastructure.

 

Key Points

National Grid facility in Kent that steps voltage, regulates power, and connects offshore wind to strengthen UK grid.

✅ Adds 2 GW capacity to meet rising electricity demand

✅ Integrates offshore wind farms into transmission network

✅ Improves reliability, voltage control, and grid resilience

 

The United Kingdom has strengthened its national power grid with the commissioning of a major new 2-gigawatt capacity substation in Kent. This massive project, a key part of the National Grid's ongoing efforts to modernize and expand power transmission infrastructure, including plans to fast-track grid connections across critical projects, will play a critical role in supporting the UK's energy transition and growing electricity demands.


What is a Substation?

Substations are vital components of electricity grids. They serve as connection points, transforming high voltage electricity from power plants to lower voltages suitable for homes and businesses. They also help to regulate voltage levels, and, where appropriate, interface with expanding HVDC technology initiatives, ensuring stable electricity delivery.  Modern substations often act as hubs, supporting the integration of renewable power sources with the main electricity network.


Why This Substation Is Important

The new 2-gigawatt capacity substation is significant for several reasons:

  • Expanding Capacity: It adds significant capacity to the UK's grid, enabling the transmission of large amounts of electricity to where it's needed. This capacity boost is crucial for supporting growing electricity demand as the UK shifts its energy mix towards renewable sources.
  • Integrating Renewables: The substation will aid in integrating substantial amounts of offshore wind power, as projects like the Scotland-England subsea link illustrate, helping the UK achieve its ambitious clean energy goals. Offshore wind farms are a booming source of renewable energy in the UK, and ensuring reliable connections to the grid is essential in maximizing their potential.
  • Future-Proofing the Grid: The newly commissioned substation helps bolster the reliability and resilience of the UK's power transmission network, where reducing losses with superconducting cables could further enhance efficiency. It will play a key role in securing electricity supplies as older power plants are decommissioned and renewable energy sources become more dominant.


A Landmark Project

The commissioning of this substation is a major achievement for the National Grid, amid an independent operator transition underway in the sector, and UK energy infrastructure upgrades. The sheer scale of the project required extensive planning and collaboration with various stakeholders, underscoring the complexity of upgrading the nation's power grid to meet future needs.


The Path Towards a Cleaner Grid

The new substation is not an isolated project. It is part of a broader, multi-year effort by the National Grid to modernize and expand the country's power grid.  This entails building new transmission lines and urban conduits such as London's newest electricity tunnel now in service, investing in storage technologies, and adapting infrastructure to accommodate the shift towards distributed energy generation, where power is generated closer to the point of use.


Beyond Substations

While projects like the new 2-gigawatt substation are crucial, ensuring a successful energy transition requires more than just infrastructure upgrades. Continued support for renewable energy development, highlighted by recent offshore wind power milestones that demonstrate grid-readiness, investment in emerging energy storage solutions, and smart grid technology that leverages data for effective grid management are all important components of building a cleaner and more resilient energy future for the UK.

Energize America: Invest in a smarter electricity infrastructure

Smart Grid Modernization unites distributed energy resources, energy storage, EV charging, advanced metering, and bidirectional power flows to upgrade transmission and distribution infrastructure for reliability, resilience, cybersecurity, and affordable, clean power.

 

Key Points

Upgrading grid hardware and software to integrate DERs, storage, and EVs for a reliable and affordable power system.

✅ Enables DER, storage, and EV integration with bidirectional flows

✅ Improves reliability, resilience, and grid cybersecurity

✅ Requires early investment in sensors, inverters, and analytics

 

Much has been written, predicted, and debated in recent years about the future of the electricity system. The discussion isn’t simply about fossil fuels versus renewables, as often dominates mainstream energy discourse. Rather, the discussion is focused on something much larger and more fundamental: the very design of how and where electricity should be generated, delivered, and consumed.

Central to this discussion are arguments in support of, or in opposition to, the traditional model versus that of the decentralized or “emerging” model. But this is a false choice. The only choice that needs making is how to best transition to a smarter grid, and do so in a reliable and affordable manner that reflects grid modernization affordability concerns for utilities today. And the most effective and immediate means to accomplish that is to encourage and facilitate early investment in grid-related infrastructure and technology.

The traditional, or centralized, model has evolved since the days of Thomas Edison, but the basic structure is relatively unchanged: generate electrons at a central power plant, transmit them over a unidirectional system of high-voltage transmission lines, and deliver them to consumers through local distribution networks. The decentralized, or emerging, model envisions a system that moves away from the central power station as the primary provider of electricity to a system in which distributed energy resources, energy storage, electric vehicles, peer-to-peer transactions, connected appliances and devices, and sophisticated energy usage, pricing, and load management software play a more prominent role.

Whether it’s a fully decentralized and distributed power system, or the more likely centralized-decentralized hybrid, it is apparent that the way in which electricity is produced, delivered, and consumed will differ from today’s traditional model. And yet, in many ways, the fundamental design and engineering that makes up today’s electric grid will serve as the foundation for achieving a more distributed future. Indeed, as the transition to a smarter grid ramps up, the grid’s basic structure will remain the underlying commonality, allowing the grid to serve as a facilitator to integrate emerging technologies, including EV charging stations, rooftop solar, demand-side management software, and other distributed energy resources, while maximizing their potential benefits and informing discussions about California’s grid reliability under ambitious transition goals.

A loose analogy here is the internet. In its infancy, the internet was used primarily for sending and receiving email, doing homework, and looking up directions. At the time, it was never fully understood that the internet would create a range of services and products that would impact nearly every aspect of everyday life from online shopping, booking travel, and watching television to enabling the sharing economy and the emerging “Internet of Things.”

Uber, Netflix, Amazon, and Nest would not be possible without the internet. But the rapid evolution of the internet did not occur without significant investment in internet-related infrastructure. From dial-up to broadband to Wi-Fi, companies have invested billions of dollars to update and upgrade the system, allowing the internet to maximize its offerings and give way to technological breakthroughs, innovative businesses, and ways to share and communicate like never before.  

The electric grid is similar; it is both the backbone and the facilitator upon which the future of electricity can be built. If the vision for a smarter grid is to deploy advanced energy technologies, create new business models, and transform the way electricity is produced, distributed, and consumed, then updating and modernizing existing infrastructure and building out new intelligent infrastructure need to be top priorities. But this requires money. To be sure, increased investment in grid-related infrastructure is the key component to transitioning to a smarter grid; a grid capable of supporting and integrating advanced energy technologies within a more digital grid architecture that will result in a cleaner, more modern and efficient, and reliable and secure electricity system.

The inherent challenges of deploying new technologies and resources — reliability, bidirectional flow, intermittency, visibility, and communication, to name a few, as well as emerging climate resilience concerns shaping planning today, are not insurmountable and demonstrate exactly why federal and state authorities and electricity sector stakeholders should be planning for and making appropriate investment decisions now. My organization, Alliance for Innovation and Infrastructure, will release a report Wednesday addressing these challenges facing our infrastructure, and the opportunities a distributed smart grid would provide. From upgrading traditional wires and poles and integrating smart power inverters and real-time sensors to deploying advanced communications platforms and energy analytics software, there are numerous technologies currently available and capable of being deployed that warrant investment consideration.

Making these and similar investments will help to identify and resolve reliability issues earlier, and address vulnerabilities identified in the latest power grid report card findings, which in turn will create a stronger, more flexible grid that can then support additional emerging technologies, resulting in a system better able to address integration challenges. Doing so will ease the electricity evolution in the long-term and best realize the full reliability, economic, and environmental benefits that a smarter grid can offer.

Alberta's Last Coal Plant Closes, Embracing Clean Energy

Alberta Coal Phase-Out signals a clean energy transition, replacing coal with natural gas and renewables, cutting greenhouse gas emissions, leveraging a carbon levy, and supporting workers in Alberta's evolving electricity market.

 

Key Points

Alberta Coal Phase-Out moves power from coal to lower-emission natural gas and renewables to reduce grid emissions.

✅ Last coal plant closed: Genesee Generating Station, Sept 30, 2023

✅ Shift to natural gas and renewables lowers emissions

✅ Carbon levy and incentives accelerated clean power build-out

 

The closure of the Genesee Generating Station on September 30, 2023, marked a significant milestone in Alberta's energy history, as the province moved to retire coal power by 2023 ahead of its 2030 provincial deadline. The Genesee, located near Calgary, was the province's last remaining coal-fired power plant. Its closure represents the culmination of a multi-year effort to transition Alberta's electricity sector away from coal and towards cleaner sources of energy.

For decades, coal was the backbone of Alberta's electricity grid. Coal-fired plants were reliable and relatively inexpensive to operate. However, coal also has a significant environmental impact. The burning of coal releases greenhouse gases, including carbon dioxide, a major contributor to climate change. Coal plants also produce air pollutants such as sulfur dioxide and nitrogen oxide, which can cause respiratory problems and acid rain, and in some regions electricity is projected to get dirtier as gas use expands.

In recognition of these environmental concerns, the Alberta government began to develop plans to phase out coal-fired power generation in the early 2000s. The government implemented a number of policies to encourage the shift from coal to cleaner energy such as natural gas and renewable energy. These policies included providing financial incentives for the construction of new natural gas plants and renewable energy facilities, as well as imposing a carbon levy on coal-fired generation.

The phase-out of coal was also driven by economic factors. The cost of natural gas has declined significantly in recent years, making it a more competitive fuel source for electricity generation as producers switch to gas under evolving market conditions. Additionally, the Alberta government faced increasing pressure from the federal government to reduce greenhouse gas emissions.

The transition away from coal has not been without its challenges. Coal mining and coal-fired power generation have long been important parts of Alberta's economy. The closure of coal plants has resulted in job losses in the affected communities. The government has implemented programs to help workers transition to new jobs in the clean energy sector.

Despite these challenges, the closure of the Genesee Generating Station is a positive development for Alberta's environment and climate. Coal-fired power generation is one of the largest sources of greenhouse gas emissions in Alberta, and recent wind generation outpacing coal underscores the sector's transformation. The closure of the Genesee is expected to result in a significant reduction in emissions, helping Alberta to meet its climate change targets.

The transition away from coal also presents opportunities for Alberta. The province has vast natural gas resources, which can be used to generate electricity with lower emissions than coal. Alberta is also well-positioned to develop renewable energy sources, such as wind power and solar power. These renewable energy sources can help to further reduce emissions and create new jobs in the clean energy sector.

The closure of the Genesee Generating Station is a significant milestone in Alberta's energy history. It represents the end of an era for coal-fired power generation in the province, a shift mirrored by the UK's last coal station going offline earlier this year. However, it also marks the beginning of a new era for Alberta's energy sector. By transitioning to cleaner sources of energy, Alberta can reduce its environmental impact and create a more sustainable energy future.

EV Sales Still Behind Gas Cars

U.S. EV and Hybrid Sales 2024 show slower adoption versus gas-powered cars, as charging infrastructure gaps, range anxiety, higher upfront costs, and affordability concerns persist despite incentives, battery tech advances, and expanding fast-charging networks.

 

Key Points

They represent 10-15% of U.S. car sales, lagging gas models due to costs, charging gaps, range anxiety, and access.

✅ 10-15% of U.S. auto sales; gas cars dominate

✅ Barriers: upfront cost, limited charging, range anxiety

✅ Incentives, battery tech, and networks may boost adoption

 

Sales of hybrid and electric vehicles (EVs) in the U.S. are continuing to trail behind traditional gas-powered vehicles in 2024, despite significant advancements in automotive technology and growing public awareness of environmental concerns. While the electric vehicle market has seen steady growth and recent sales momentum over the past few years, the gap between EVs and gasoline-powered cars remains wide.

In 2024, hybrid and electric vehicles are projected to account for roughly 10-15% of total car sales in the U.S., a figure that, though significant, still lags far behind the sales of gas-powered vehicles and follows a Q1 2024 EV market share dip in the U.S., according to recent data. Analysts point to several factors contributing to this slower adoption rate, including higher upfront costs, limited charging infrastructure, and consumer concerns over range anxiety. Additionally, while EVs and hybrids offer lower lifetime operating costs, the initial price difference remains a hurdle for many prospective buyers.

One of the key challenges for EV sales continues to be the perception of cost, even as analyses show they can be better for the planet and often your budget over time. While federal and state incentives have made EVs more affordable, especially for lower-income buyers, the price tag for many electric models remains steep, particularly for higher-end vehicles. Even with government rebates, EVs can still be priced higher than their gasoline counterparts, making them less accessible for middle-class consumers. Many potential buyers are also hesitant to make the switch, unsure if the long-term savings will outweigh the initial investment.

Another critical factor is the limited charging infrastructure in many parts of the country. Though major cities have seen significant improvements in charging stations, rural areas and smaller towns still lack the necessary infrastructure to support widespread EV use. This uneven distribution of charging stations leads to concerns about being stranded in areas without access to fast-charging options. While automakers are working on expanding charging networks, the pace of this development is slow, and EVs won't go mainstream until key problems are fixed according to industry leaders.

Range anxiety is also a continuing issue, despite improvements in battery technology. Though newer electric vehicles can go further on a single charge than ever before, the range of many EVs still doesn't meet the expectations of some drivers, particularly those who regularly take long road trips or live in rural areas. The longer charging times and the necessity of planning routes around charging stations add to the hesitation, especially when gasoline-powered vehicles provide greater convenience and flexibility.

The shift toward EVs is further hindered by the continued dominance of gas-powered cars in the market. Gasoline vehicles benefit from decades of development, an extensive fueling infrastructure, and familiarity with the technology. For many consumers, the convenience, affordability, and ease of use of gas-powered vehicles still outweigh the benefits of switching to an electric alternative. Additionally, with fluctuating fuel prices, many drivers continue to find gas-powered cars relatively cost-effective in terms of daily commuting, especially when compared to the current costs of EV ownership.

Despite these challenges, there is hope for a future shift. The federal government’s push for stricter emissions regulations and tax incentives continues to fuel growth in the electric vehicle market. As automakers ramp up production and more affordable options become available, EV sales are expected to increase in the coming years. Companies like Tesla, Ford, whose hybrids are getting a boost, and General Motors are leading the charge, while new manufacturers like Rivian and Lucid Motors are offering alternatives to traditional gasoline vehicles.

Furthermore, the development of new technologies, such as solid-state batteries and faster charging systems, could help alleviate some of the current drawbacks of electric vehicles. If these advancements reach mass-market production in the next few years, they could help make EVs a more attractive and practical option for consumers, aligning with within-a-decade adoption forecasts from some industry observers.

In conclusion, while hybrid and electric vehicles are growing in popularity, gas-powered vehicles continue to dominate the U.S. car market in 2024. Challenges such as high upfront costs, limited charging infrastructure, and concerns about range persist, making it difficult for many consumers to make the switch to electric even as they ask if it's time to buy an EV in 2024. However, with continued investment in technology and infrastructure, the gap between EVs and gas-powered vehicles could narrow in the years to come.
