The Williams Lake Energy Plant, currently operated by EPCOR, on behalf of EPCOR Power LP, is one of the largest bioenergy facilities in North America. The plant demonstrates that the government's Bioenergy Strategy goals of reducing greenhouse gas emissions and providing electricity self-sufficiency are achievable.

"The Williams Lake energy plant has long demonstrated how bioenergy fuels can deliver clean and reliable power to British Columbia," said EPCOR BC vice president Fred Shafai. "EPCOR supports the B.C. Government's move to further expand opportunities for this fuel type and we are developing plans for similar plants, building on the success at Williams Lake and using the forestry residue and beetle-killed pine trees as fuel."

On average, 80 to 100 truck loads of wood-waste material arrive at the plant every weekday from area sawmills, amounting to over 600,000 tonnes annually. Over the last 15 years, the energy plant has eliminated nine million tonnes of wood-waste that would have previously been disposed in beehive burners. The beetle-killed timber used in the plant also eliminates the natural production of methane, a greenhouse gas that is 21 times more potent than CO(2), created when the timber is left to rot.

In 2007 the 66 megawatt facility generated enough carbon-neutral electricity to meet the average annual needs of 89,000 homes in B.C. Twenty-eight full-time staff operate this state-of-the-art facility, which is equipped with combustion and emission controls. The plant surpasses all air emissions permit levels that are already five times more stringent than existing regulations for wood-waste-fired boilers.

"I'm very proud of the commitment our staff have to operating this facility in the safest, most environmentally friendly manner possible," said Plant Manager Geoff Wagner. "We all recognize the importance of this plant to the community and to the local economy."

By operating using fuel from wood waste, the plant has delivered a solution to a long-standing air quality problem in the area caused by beehive burners.

"Air quality in Williams Lake was a major concern before the energy plant," said Williams Lake Mayor Scott Nelson. "The energy plant not only provided an effective solution of disposing of the area's wood-waste, it has provided a carbon neutral source of electricity, fantastic jobs, and has long been the city's biggest tax-payer."

The plant began generating power in the spring of 1993 and marks its 15th anniversary in 2008. EPCOR assumed operation of the facility in September 2005.

Lawmakers push bill to connect Texas grid to rest of the nation

Connect the Grid Act links ERCOT to neighboring grids via high-voltage interconnections, enhancing reliability, resilience, and renewables integration. It enables power imports and exports with SPP, MISO, and the Western Interconnection under FERC oversight.

 

Key Points

A plan to link ERCOT with neighboring grids, improving reliability, enabling energy trade, and integrating renewables.

✅ High-voltage ties with SPP, MISO, and the Western Interconnection

✅ Enables imports during crises and exports of surplus power

✅ Brings ERCOT under FERC oversight; DoE to study Mexico links

 

In the aftermath of the devastating 2021 Texas blackouts, which exposed the vulnerabilities of the state's energy infrastructure, a significant legislative effort is underway to transform Texas from an energy island into a connected component of the broader U.S. power grid. Spearheaded by U.S. Representative Greg Casar, D-Austin, the proposed Connect the Grid Act is part of a push for smarter electricity infrastructure that seeks to remedy the isolation of the Electric Reliability Council of Texas (ERCOT) from neighboring power grids, a condition that significantly contributed to the crisis during Winter Storm Uri.

The blackouts, which left millions without power and resulted in significant loss of life and economic damage, underscored the inherent risks of Texas's unique energy infrastructure. Unlike the rest of the continental U.S., Texas's grid operates independently, limiting its ability to import electricity during emergencies. This isolation was a critical factor in the state's inability to respond effectively to the increased demand for power during the storm.

Recognizing the urgent need for a more resilient and integrated energy system, Rep. Casar's legislation aims to establish high-voltage connections between ERCOT and adjacent grid-operating organizations, including the Southern Power Pool, MISO, and the Western Interconnection. This would not only improve the reliability of Texas's power supply by enabling energy imports during crises but also allow the state to export surplus energy, thereby enhancing the economic efficiency and sustainability of its energy market.

The Connect the Grid Act proposes a range for the new connections' transfer capabilities, aiming to significantly boost the amount of power that can be shared between Texas and its neighbors. Such interconnectivity is anticipated to reduce energy costs for consumers by mitigating scarcity and enabling access to Texas's vast renewable energy resources, even as grid modernization affordability remains a point of debate among stakeholders. However, the bill faces opposition due to concerns over federal oversight, as it would bring ERCOT under the jurisdiction of the Federal Energy Regulatory Commission (FERC).

Some analysts note that policies such as later school start dates can ease late-summer peak demand as well.

At a press conference held at the IBEW Local 520 headquarters, Rep. Casar, along with environmental groups, labor unions, and frontline workers, highlighted the benefits of the proposed legislation. The bill also includes provisions for a Department of Energy study on the potential benefits of interconnecting with Mexico, and parallels proposals for macrogrids in Canada that seek greater reliability across borders.

The Connect the Grid Act reflects a broader national trend towards increasing the interconnectivity of regional power grids, a move deemed essential for the transition to renewable energy and combating climate change risks to the U.S. grid through expanded interconnection. By enabling the flow of clean energy from renewable-rich areas like Texas to energy-hungry urban centers, the legislation supports a more sustainable and resilient national energy infrastructure.

Critics of Texas's grid independence, including energy experts and federal regulators, have long advocated for such interconnections. They argue that increased access to neighboring grids could have mitigated the effects of the 2021 blackouts and emphasize the importance of a grid that can withstand extreme weather events. The Federal Energy Regulatory Commission and the North American Electric Reliability Corp. have both explored mandates and studies to promote electricity transfer between regional grids, while states like California grid upgrades are investing to modernize networks as well, highlighting the national importance of grid interconnectivity.

Despite the potential challenges of increased federal regulation, proponents of the Connect the Grid Act argue that the benefits of interconnection far outweigh the drawbacks. By reducing energy costs, enhancing grid reliability, and promoting renewable energy, the legislation aims to secure a more sustainable and equitable energy future for Texas and the nation.

If passed, the Connect the Grid Act would mark a historic shift in Texas's energy policy, ending the state's long-standing isolation and positioning it as a key player in the national and potentially international energy landscape, and echoes calls for a western Canadian electricity grid to strengthen regional ties. The bill sets a completion deadline of January 1, 2035, for the construction of the new connections, with other projects, like the one by Pattern Energy, potentially connecting ERCOT to parts of the Southeastern grid even earlier, by 2029. This legislative effort represents a critical step towards ensuring that Texas can meet its energy needs reliably and sustainably, while also contributing to the broader goal of transitioning to a cleaner, more resilient power system.

Renewables surpass coal in US energy generation for first time in 130 years

Renewables Overtake Coal in the US, as solar, wind, and hydro expand grid share; EIA data show an energy transition accelerated by COVID-19, slashing emissions, displacing fossil fuels, and reshaping electricity generation and climate policy.

 

Key Points

It refers to the milestone where US renewable energy generation surpassed coal, marking a pivotal energy transition.

✅ EIA data show renewables topped coal consumption in 2019.

✅ Solar, wind, and hydro displaced aging, costly coal plants.

✅ COVID-19 demand drop accelerated the energy transition.

 

Solar, wind and other renewable sources have toppled coal in energy generation in the United States for the first time in over 130 years, with the coronavirus pandemic accelerating a decline in coal that has profound implications for the climate crisis.

Not since wood was the main source of American energy in the 19th century has a renewable resource been used more heavily than coal, but 2019 saw a historic reversal, building on wind and solar reaching 10% of U.S. generation in 2018, according to US government figures.

Coal consumption fell by 15%, down for the sixth year in a row, while renewables edged up by 1%, even as U.S. electricity use trended lower. This meant renewables surpassed coal for the first time since at least 1885, a year when Mark Twain published The Adventures of Huckleberry Finn and America’s first skyscraper was erected in Chicago.

Electricity generation from coal fell to its lowest level in 42 years in 2019, with the US Energy Information Administration (EIA) forecasting that renewables will eclipse coal as an electricity source this year, while a global eclipse by 2025 is also projected. On 21 May, the year hit its 100th day in which renewables have been used more heavily than coal.

“Coal is on the way out, we are seeing the end of coal,” said Dennis Wamsted, analyst at the Institute for Energy Economics and Financial Analysis. “We aren’t going to see a big resurgence in coal generation, the trend is pretty clear.”

The ongoing collapse of coal would have been nearly unthinkable a decade ago, when the fuel source accounted for nearly half of America’s generated electricity, even as a brief uptick in 2021 was anticipated. That proportion may fall to under 20% this year, with analysts predicting a further halving within the coming decade.

A rapid slump since then has not been reversed despite the efforts of the Trump administration, which has dismantled a key Barack Obama-era climate rule to reduce emissions from coal plants and eased requirements that prevent coal operations discharging mercury into the atmosphere and waste into streams.

Coal releases more planet-warming carbon dioxide than any other energy source, with scientists warning its use must be rapidly phased out to achieve net-zero emissions globally by 2050 and avoid the worst ravages of the climate crisis.

Countries including the UK and Germany are in the process of winding down their coal sectors, and in Europe renewables are increasingly crowding out gas as well, although in the US the industry still enjoys strong political support from Trump.

“It’s a big moment for the market to see renewables overtake coal,” said Ben Nelson, lead coal analyst at Moody’s. “The magnitude of intervention to aid coal has not been sufficient to fundamentally change its trajectory, which is sharply downwards.”

Nelson said he expects coal production to plummet by a quarter this year but stressed that declaring the demise of the industry is “a very tough statement to make” due to ongoing exports of coal and its use in steel-making. There are also rural communities with power purchase agreements with coal plants, meaning these contracts would have to end before coal use was halted.

The coal sector has been beset by a barrage of problems, predominantly from cheap, abundant gas that has displaced it as a go-to energy source. The Covid-19 outbreak has exacerbated this trend, even as global power demand has surged above pre-pandemic levels. With plunging electricity demand following the shutting of factories, offices and retailers, utilities have plenty of spare energy to choose from and coal is routinely the last to be picked because it is more expensive to run than gas, solar, wind or nuclear.

Many US coal plants are ageing and costly to operate, forcing hundreds of closures over the past decade. Just this year, power companies have announced plans to shutter 13 coal plants, including the large Edgewater facility outside Sheboygan, Wisconsin, the Coal Creek Station plant in North Dakota and the Four Corners generating station in New Mexico – one of America’s largest emitters of carbon dioxide.

The last coal facility left in New York state closed earlier this year.

The additional pressure of the pandemic “will likely shutter the US coal industry for good”, said Yuan-Sheng Yu, senior analyst at Lux Research. “It is becoming clear that Covid-19 will lead to a shake-up of the energy landscape and catalyze the energy transition, with investors eyeing new energy sector plays as we emerge from the pandemic.”

Climate campaigners have cheered the decline of coal but in the US the fuel is largely being replaced by gas, which burns more cleanly than coal but still emits a sizable amount of carbon dioxide and methane, a powerful greenhouse gas, in its production, whereas in the EU wind and solar overtook gas last year.

Renewables accounted for 11% of total US energy consumption last year – a share that will have to radically expand if dangerous climate change is to be avoided. Petroleum made up 37% of the total, followed by gas at 32%. Renewables marginally edged out coal, while nuclear stood at 8%.

“Getting past coal is a big first hurdle but the next round will be the gas industry,” said Wamsted. “There are emissions from gas plants and they are significant. It’s certainly not over.”

In Europe, A Push For Electricity To Solve The Climate Dilemma

EU Electrification Strategy 2050 outlines shifting transport, buildings, and industry to clean power, accelerating EV adoption, heat pumps, and direct electrification to meet targets, reduce emissions, and replace fossil fuels with renewables and low-carbon grids.

 

Key Points

EU plan to cut emissions 95% by 2050 by electrifying transport, buildings and industry with clean power.

✅ 60% of final energy from electricity by 2050

✅ EVs dominate transport; up to 63% electric share

✅ Heat pumps electrify buildings; industry to 50% direct

 

The European Union has one of the most ambitious carbon emission reduction goals under the global Paris Agreement on climate change – a 95% reduction by 2050.

It seems that everyone has an idea for how to get there. Some are pushing nuclear energy. Others are pushing for a complete phase-out of fossil fuels and a switch to renewables.

Today the European electricity industry came out with their own plan, amid expectations of greater electricity price volatility in Europe in the coming years. A study published today by Eurelectric, the trade body of the European power sector, concludes that the 2050 goal will not be possible without a major shift to electricity in transport, buildings and industry.

The study finds that for the EU to reach its 95% emissions reduction target, electricity needs to cover at least 60 percent of final energy consumption by 2050. This would require a 1.5 percent year-on-year growth of EU electricity use, with evidence that EVs could raise electricity demand significantly in other markets, while at the same time reducing the EU’s overall energy consumption by 1.3 percent per year.

#google#

Transport is one of the areas where electrification can deliver the most benefit, because an electric car causes far less carbon emissions than a conventional vehicle, with e-mobility emerging as a key driver of electricity demand even if that electricity is generated in a fossil fuel power plant.

In the most ambitious scenario presented by the study, up to 63 percent of total final energy consumption in transport will be electric by 2050, and some analyses suggest that mass adoption of electric cars could occur much sooner, further accelerating progress.

Building have big potential as well, according to the study, with 45 to 63 percent of buildings energy consumption could be electric in 2050 by converting to electric heat pumps. Industrial processes could technically be electrified with up to 50 percent direct electrification in 2050, according to the study. The relative competitiveness of electricity against other carbon-neutral fuels will be the critical driver for this shift, but grid carbon intensity differs across markets, such as where fossil fuels still supply a notable share of generation.

How to Get Solar Power on a Rainy Day? Beam It From Space

Space solar power promises wireless energy from orbital solar satellites via microwave or laser power beaming, using photovoltaics and rectennas. NRL and AFRL advances hint at 24-7 renewable power delivery to Earth and airborne drones.

 

Key Points

Space solar power beams orbital solar energy to Earth via microwaves or lasers, enabling continuous wireless electricity.

✅ Harvests sunlight in orbit and transmits via microwaves or lasers

✅ Provides 24-7 renewable power, independent of weather or night

✅ Enables wireless power for remote sites, grids, and drones

 

Earlier this year, a small group of spectators gathered in David Taylor Model Basin, the Navy’s cavernous indoor wave pool in Maryland, to watch something they couldn’t see. At each end of the facility there was a 13-foot pole with a small cube perched on top. A powerful infrared laser beam shot out of one of the cubes, striking an array of photovoltaic cells inside the opposite cube. To the naked eye, however, it looked like a whole lot of nothing. The only evidence that anything was happening came from a small coffee maker nearby, which was churning out “laser lattes” using only the power generated by the system as ambitions for cheap abundant electricity gain momentum worldwide.

The laser setup managed to transmit 400 watts of power—enough for several small household appliances—through hundreds of meters of air without moving any mass. The Naval Research Lab, which ran the project, hopes to use the system to send power to drones during flight. But NRL electronics engineer Paul Jaffe has his sights set on an even more ambitious problem: beaming solar power to Earth from space. For decades the idea had been reserved for The Future, but a series of technological breakthroughs and a massive new government research program suggest that faraway day may have finally arrived as interest in space-based solar broadens across industry and government.

Since the idea for space solar power first cropped up in Isaac Asimov’s science fiction in the early 1940s, scientists and engineers have floated dozens of proposals to bring the concept to life, including inflatable solar arrays and robotic self-assembly. But the basic idea is always the same: A giant satellite in orbit harvests energy from the sun and converts it to microwaves or lasers for transmission to Earth, where it is converted into electricity. The sun never sets in space, so a space solar power system could supply renewable power to anywhere on the planet, day or night, as recent tests show we can generate electricity from the night sky as well, rain or shine.

Like fusion energy, space-based solar power seemed doomed to become a technology that was always 30 years away. Technical problems kept cropping up, cost estimates remained stratospheric, and as solar cells became cheaper and more efficient, and storage improved with cheap batteries, the case for space-based solar seemed to be shrinking.

That didn’t stop government research agencies from trying. In 1975, after partnering with the Department of Energy on a series of space solar power feasibility studies, NASA beamed 30 kilowatts of power over a mile using a giant microwave dish. Beamed energy is a crucial aspect of space solar power, but this test remains the most powerful demonstration of the technology to date. “The fact that it’s been almost 45 years since NASA’s demonstration, and it remains the high-water mark, speaks for itself,” Jaffe says. “Space solar wasn’t a national imperative, and so a lot of this technology didn’t meaningfully progress.”

John Mankins, a former physicist at NASA and director of Solar Space Technologies, witnessed how government bureaucracy killed space solar power development firsthand. In the late 1990s, Mankins authored a report for NASA that concluded it was again time to take space solar power seriously and led a project to do design studies on a satellite system. Despite some promising results, the agency ended up abandoning it.

In 2005, Mankins left NASA to work as a consultant, but he couldn’t shake the idea of space solar power. He did some modest space solar power experiments himself and even got a grant from NASA’s Innovative Advanced Concepts program in 2011. The result was SPS-ALPHA, which Mankins called “the first practical solar power satellite.” The idea, says Mankins, was “to build a large solar-powered satellite out of thousands of small pieces.” His modular design brought the cost of hardware down significantly, at least in principle.

Jaffe, who was just starting to work on hardware for space solar power at the Naval Research Lab, got excited about Mankins’ concept. At the time he was developing a “sandwich module” consisting of a small solar panel on one side and a microwave transmitter on the other. His electronic sandwich demonstrated all the elements of an actual space solar power system and, perhaps most important, it was modular. It could work beautifully with something like Mankins' concept, he figured. All they were missing was the financial support to bring the idea from the laboratory into space.

Jaffe invited Mankins to join a small team of researchers entering a Defense Department competition, in which they were planning to pitch a space solar power concept based on SPS-ALPHA. In 2016, the team presented the idea to top Defense officials and ended up winning four out of the seven award categories. Both Jaffe and Mankins described it as a crucial moment for reviving the US government’s interest in space solar power.

They might be right. In October, the Air Force Research Lab announced a $100 million program to develop hardware for a solar power satellite. It’s an important first step toward the first demonstration of space solar power in orbit, and Mankins says it could help solve what he sees as space solar power’s biggest problem: public perception. The technology has always seemed like a pie-in-the-sky idea, and the cost of setting up a solar array on Earth is plummeting, as proposals like a tenfold U.S. solar expansion signal rapid growth; but space solar power has unique benefits, chief among them the availability of solar energy around the clock regardless of the weather or time of day.

It can also provide renewable energy to remote locations, such as forward operating bases for the military, which has deployed its first floating solar array to bolster resilience. And at a time when wildfires have forced the utility PG&E to kill power for thousands of California residents on multiple occasions, having a way to provide renewable energy through the clouds and smoke doesn’t seem like such a bad idea. (Ironically enough, PG&E entered a first-of-its-kind agreement to buy space solar power from a company called Solaren back in 2009; the system was supposed to start operating in 2016 but never came to fruition.)

“If space solar power does work, it is hard to overstate what the geopolitical implications would be,” Jaffe says. “With GPS, we sort of take it for granted that no matter where we are on this planet, we can get precise navigation information. If the same thing could be done for energy, especially as peer-to-peer energy sharing matures, it would be revolutionary.”

Indeed, there seems to be an emerging race to become the first to harness this technology. Earlier this year China announced its intention to become the first country to build a solar power station in space, and for more than a decade Japan has considered the development of a space solar power station to be a national priority. Now that the US military has joined in with a $100 million hardware development program, it may only be a matter of time before there’s a solar farm in the solar system.

In a significant step toward sustainable transportation, the Switch-On project is bringing 70 Volvo VNR Electric trucks to California. This initiative aims to bolster the state's efforts to reduce emissions and transition to greener logistics solutions. The arrival of these electric vehicles marks an important milestone in California's commitment to combating climate change and improving air quality.

The Switch-On Project: Overview and Goals

The Switch-On project is a collaborative effort designed to enhance electric truck adoption in California. It focuses on developing the necessary infrastructure and technology to support electric vehicles (EVs) in the freight and logistics sectors, building on recent nonprofit investments at California ports. The project not only seeks to increase the availability of electric trucks but also aims to demonstrate their effectiveness in real-world applications.

California has set ambitious goals for reducing greenhouse gas emissions, particularly from the transportation sector, which is one of the largest contributors to air pollution. By introducing electric trucks into freight operations, the state aims to significantly cut emissions, improve public health, and pave the way for a more sustainable future.

The Volvo VNR Electric Trucks

The Volvo VNR Electric trucks are specifically designed for regional distribution and urban transport, aligning with Volvo's broader electric lineup as the company expands offerings, making them ideal for the needs of California’s freight industry. With a range of approximately 250 miles on a single charge, these trucks can efficiently handle most regional routes. Equipped with advanced technology, including regenerative braking and connectivity features, the VNR Electric models enhance operational efficiency and safety.

These trucks not only provide a cleaner alternative to traditional diesel vehicles but also promise lower operational costs over time. With reduced fuel expenses and lower maintenance needs, and emerging vehicle-to-grid pilots that can create new value streams, businesses can benefit from significant savings while contributing to environmental sustainability.

Canadian Electricity Grids Increasingly Exposed to Harsh Weather

North American Grid Reliability faces extreme weather, climate change, demand spikes, and renewable variability; utilities, AESO, and NERC stress resilience, dispatchable capacity, interconnections, and grid alerts to prevent blackouts during heatwaves and cold snaps.

 

Key Points

North American grid reliability is the ability to meet demand during extreme weather while maintaining stability.

✅ Extreme heat and cold drive record demand and resource strain.

✅ Balance dispatchable and intermittent generation for resilience.

✅ Expand interconnections, capacity, and demand response to avert outages.

 

The recent alerts in Alberta's electricity grid during extreme cold have highlighted a broader North American issue, where power systems are more susceptible to being overwhelmed by extreme weather impacts on reliability.

Electricity Canada's chief executive emphasized that no part of the grid is safe from the escalating intensity and frequency of weather extremes linked to climate change across the sector.

“In recent years, during these extreme weather events, we’ve observed record highs in electricity demand,” he stated.

“It’s a nationwide phenomenon. For instance, last summer in Ontario and last winter in Quebec, we experienced unprecedented demand levels. This pattern of extremes is becoming more pronounced across the country.”

The U.S. has also experienced strain on its electricity grids due to extreme weather, with more blackouts than peers documented in studies. Texas faced power outages in 2021 due to winter storms, and California has had to issue several emergency grid alerts during heat waves.

In Canada, Albertans received a government emergency alert two weeks ago, urging an immediate reduction in electricity use to prevent potential rotating blackouts as temperatures neared -40°C. No blackouts occurred, with a notable decrease in electricity use following the alert, according to the Alberta Electric System Operator (AESO).

AESO's data indicates an increase in grid alerts in Alberta for both heatwaves and cold spells, reflecting dangerous vulnerabilities noted nationwide. The period between 2017 and 2020 saw only four alerts, in contrast to 17 since 2021.

Alberta's electricity grid reliability has sparked political debate, including proposals for a western Canadian grid to improve reliability, particularly with the transition from coal-fired plants to increased reliance on intermittent wind and solar power. Despite this debate, the AESO noted that the crisis eased when wind and solar generation resumed, despite challenges with two idled gas plants.

Bradley pointed out that Alberta's grid issues are not isolated. Every Canadian region is experiencing growing electricity demand, partly due to the surge in electric vehicles and clean energy technologies. No province has a complete solution yet.

“Ontario has had to request reduced consumption during heatwaves,” he noted. “Similar concerns about energy mix are present in British Columbia or Manitoba, especially now with drought affecting their hydro-dependent systems.”

The North American Electric Reliability Corporation (NERC) released a report in November warning of elevated risks across North America this winter for insufficient energy supplies, particularly under extreme conditions like prolonged cold snaps.

While the U.S. is generally more susceptible to winter grid disruptions, and summer blackout warnings remain a concern, the report also highlights risks in parts of Canada. Saskatchewan faces a “high” risk due to increased demand, power plant retirements, and maintenance, whereas Quebec and the Maritimes are at “elevated risk.”

Mark Olson, NERC’s manager of reliability assessments, mentioned that Alberta wasn't initially considered at risk, illustrating the challenges in predicting electricity demand amid intensifying extreme weather.

Rob Thornton, president and CEO of the International District Energy Association, acknowledged public concerns about grid alerts but reassured that the risk of a catastrophic grid failure remains very low.

“The North American grid is exceptionally reliable. It’s a remarkably efficient system,” he said.

However, Thornton emphasized the importance of policies for a resilient and reliable electricity system through 2050 and beyond. This involves balancing dispatchable and intermittent electricity sources, investing in extra capacity, enhancing macrogrids and inter-jurisdictional connections, and more.

“These grid alerts raise awareness, if not anxiety, about our energy future,” Thornton concluded.
