Researchers will have to wait several weeks before they can adequately begin studying tidal information in Puget Sound.

The Snohomish County Public Utility District and the University of Washington are waiting for results from ongoing acoustic Doppler testing at Admiralty Inlet and Deception Pass. The PUD is considering how well each site might perform as a tidal-power location, while the UW hopes to use the information to continue mapping tidal flows throughout Puget Sound.

About two weeks ago, the two began collecting data, and it won't be until mid-September that enough information has been collected to start giving them a sense of how the waters move through both areas. Admiralty Inlet, about three miles wide, could be the PUD's best option for a tidal-power plant, says Craig Collar, the PUD's senior manager of energy-resource development.

But fast currents at Deception Pass make it too good not to study, despite other problems at the location, he said. "We're looking for strong, predictable tidal currents," Collar said. "Deception Pass, while having the highest current in Puget Sound, could be too turbulent."

Plus, environmental and aesthetic concerns would force the PUD to reconcile with several parties, including the state of Washington, before any tidal plant would be built at the state park. The PUD is counting on adding tidal power to its array of energy production in light of Initiative 937, which requires a mix of conservation measures and renewable-energy sources to make up a utility's energy base.

Under the initiative, utilities serving more than 25,000 customers - the PUD has more than 300,000 - need to get at least 15 percent of their energy from renewable resources, not including hydropower, by 2020. The PUD also needs to meet new energy needs associated with continued growth in Snohomish County.

"We estimate we'll need to add 140 average megawatts by 2020," Collar said. That's enough power for about 100,000 more homes. The seven sites scheduled for tidal-power testing could produce about 100 megawatts, according to the PUD's federal permit applications. The acoustic Doppler tests are the first completed to see how useful a location might be in providing enough wave energy to turn underwater propellers attached to turbines.

The PUD will do one round of testing this year at Admiralty Inlet and Deception Pass, then test five more sites sometime next year. Those sites are at Speiden Channel and San Juan Channel off San Juan Island, Guemes Channel near Anacortes, and Agate Passage and Rich Passage along Bainbridge Island. The first Doppler testing was done by boat and measured how tidal currents bounce off the shoreline at each site. Now, stationary devices have been placed in the water to measure currents over the course of a month. It's this long-term data that interests UW researchers as they develop a model of tidal currents throughout Puget Sound.

"Anytime you're modeling something as complex as Puget Sound, you like to have measurements to verify that modeling," said Philip Malte, a UW mechanical-engineering professor. "We're getting an initial impression now, and then as we begin to look more deeply at the data we should learn quite a bit quickly."

Ocean currents are continually shifting, so to be successful in its modeling, the UW needs to see how measurements change over time. The stationary tests will measure two tidal cycles. After tidal testing, if sites prove to have potential, the PUD will study the economics of operating tidal-power plants at those locations and begin to look at available technologies and conduct environmental tests.

The field of tidal energy is relatively new in the United States, and much will need to be done to get federal approval for any power plant, Collar said. Any tidal-power plant run by the PUD is still years away, he said.

"These are the Kitty Hawk days for tidal energy," he said, referencing the Wright Brothers' initial airplane flight in 1903. "There are still many questions to be answered."

✅ Backed by clean tech tax credits and public investment.

✅ Boosts local jobs, R&D, and clean transportation leadership.

 

The automotive industry is undergoing a seismic shift, and Canada is firmly planting its flag in the electric vehicle (EV) revolution, propelled by recent EV assembly deals across the country. A new $1.6 billion battery component plant in Ontario's Niagara Region signifies a significant step towards a cleaner, more sustainable transportation future. This Asahi Kasei facility, a key player in Honda's $15 billion electric vehicle supply chain investment, promises to create jobs, boost the local economy, and solidify Ontario's position as a leader in clean transportation technology.

Honda's ambitious project forms part of Honda's Ontario EV investment that involves constructing a dedicated battery plant adjacent to their existing Alliston, Ontario assembly facility. This new plant will focus on producing fully electric vehicles, requiring a robust supply chain for critical components. Asahi Kasei's Niagara Region plant enters the picture here, specializing in the production of battery separators – a thin film crucial for separating the positive and negative electrodes within a lithium-ion battery. These separators play a vital role in ensuring the battery functions safely and efficiently.

The Niagara Region plant is expected to be operational by 2 027, perfectly aligning with Honda's EV production timeline. This strategic partnership benefits both companies: Honda secures a reliable source for a vital component, while Asahi Kasei capitalizes on the burgeoning demand for EV parts. The project is a catalyst for economic growth in Ontario, creating jobs in construction and manufacturing, supporting an EV jobs boom province-wide, and potentially future research and development sectors. Additionally, it positions the province as a hub for clean transportation technology, attracting further investment and fostering innovation.

This announcement isn't an isolated event. News of Volkswagen constructing a separate EV battery plant in St. Thomas, Ontario, and the continuation of a major EV battery project near Montreal further underscore Canada's commitment to electric vehicles. These developments signify a clear shift in the country's automotive landscape, with a focus on sustainable solutions.

Government support has undoubtedly played a crucial role in attracting these investments. The Honda deal involves up to $5 billion in public funds. Asahi Kasei's Niagara Region plant is also expected to benefit from federal and provincial clean technology tax credits. This demonstrates a collaborative effort between government and industry, including investments by Canada and Quebec in battery assembly, to foster a thriving EV ecosystem in Canada.

The economic and environmental benefits of this project are undeniable. Battery production is expected to create thousands of jobs, while the shift towards electric vehicles will lead to reduced emissions and a cleaner environment. Ontario stands to gain significantly from this transition, becoming a leader in clean energy technology and attracting skilled workers and businesses catering to the EV sector, especially as the U.S. auto pivot to EVs accelerates across the border.

However, challenges remain. Concerns about the environmental impact of battery production, particularly the sourcing of raw materials and the potential for hazardous waste, need to be addressed. Additionally, ensuring a skilled workforce capable of handling the complexities of EV technology is paramount.

Despite these challenges, the future of electric vehicles in Canada appears bright. Major automakers are making significant investments, government support is growing, and consumer interest in EVs is on the rise. The Niagara Region plant serves as a tangible symbol of Canada's commitment to a cleaner and more sustainable transportation future. With careful planning and continued Canada-U.S. collaboration across the sector, this project has the potential to revolutionize the Canadian automotive industry and pave the way for a greener tomorrow.

Two-thirds of the U.S. is at risk of power outages this summer

Home Energy Independence reduces electricity costs and outage risks with solar panels, EV charging, battery storage, net metering, and smart inverters, helping homeowners offset tiered rates and improve grid resilience and reliability.

 

Key Points

Home Energy Independence pairs solar, batteries, and smart EV charging to lower bills and keep power on during outages.

✅ Offset rising electricity rates via solar and net metering

✅ Add battery storage for backup power and peak shaving

✅ Optimize EV charging to avoid tiered rate penalties

 

The Department of Energy recently warned that two-thirds of the U.S. is at risk of losing power this summer. It’s an increasingly common refrain: Homeowners want to be less reliant on the aging power grid and don’t want to be at the mercy of electric utilities due to rising energy costs and dwindling faith in the power grid’s reliability.

And it makes sense. While the inflated price of eggs and butter made headlines earlier this year, electricity prices quietly increased at twice the rate of overall inflation in 2022, even as studies indicate renewables aren’t making power more expensive overall, and homeowners have taken notice. In fact, according to Aurora Solar’s Industry Snapshot, 62% expect energy prices will continue to rise.

Homeowners aren’t just frustrated that electricity is pricey when they need it, they’re also worried it won’t be available at all when they feel the most vulnerable. Nearly half (48%) of homeowners are concerned about power outages stemming from weather events, or grid imbalances from excess solar in some regions, followed closely by outages due to cyberattacks on the power grid.

These concerns around reliability and cost are creating a deep lack of confidence in the power grid. Yet, despite these growing concerns, homeowners are increasingly using electricity to displace other fuel sources.

The electrification of everything
From electric heat pumps to electric stoves and clothes dryers, homeowners are accelerating the electrification of their homes. Perhaps the most exciting example is electric vehicle (EV) adoption and the need for home charging. With major vehicle makers committing to ambitious electric vehicle targets and even going all-electric in the future, EVs are primed to make an even bigger splash in the years to come.

The by-product of this electrification movement is, of course, higher electric bills because of increased consumption. Homeowners also risk paying more for every unit of energy they use if they’re part of a tiered pricing utility structure, where energy-insecure households often pay 27% more on electricity because customers are charged different rates based on the total amount of energy they use. Many new electric vehicle owners don’t realize this until they are deep into purchasing their new vehicle, or even when they open that first electric bill after the car is in their driveway.

Sure, this electrification movement can feel counterintuitive given the power grid concerns. But it’s actually the first step toward energy independence, and emerging models like peer-to-peer energy sharing could amplify that over time.

Balancing conflicting movements
The fact is that electrification is moving forward quickly, even among homeowners who are concerned about electricity prices and power grid reliability, and about why the grid isn’t yet 100% renewable in the U.S. This has the potential to lead to even more discontent with electric utilities and growing anxiety over access to electricity in extreme situations. There is a third trend, though, that can help reconcile these two conflicting movements: the growth of solar.

The popularity of solar is likely higher than you think: Nearly 77% of homeowners either have solar panels on their homes or are interested in purchasing solar. The Aurora Solar Industry Snapshot report also showed a nearly 40% year-over-year increase in residential solar projects across the U.S. in 2022, as the country moves toward 30% power from wind and solar overall, aligning with the Solar Energy Industries Association’s (SEIA) Solar Market Insight Report, which found, “Residential solar had a record year [in 2022] with nearly 6 GWdc of installations, representing 40% growth over 2021.”

It makes sense that finding ways to tamp down—even eliminate—growing bills caused by the electrification of homes is accelerating interest in solar, as more households weigh whether residential solar is worth it for their budgets, and residential solar installers are seeing this firsthand. The link between EVs and solar is a great proof point: Almost 80% of solar professionals said EV adoption often drives new interest in solar.

National Grid warns of short supply of electricity over next few days

National Grid power supply warning highlights electricity shortage risks amid low wind output, generator outages, and cold weather, reducing capacity margins and grid stability; considering demand response and reserve power to avoid blackout risk.

 

Key Points

An alert that reduced capacity from low wind and outages requires actions to maintain UK grid stability.

✅ Low wind output and generator outages reduce capacity margins

✅ ESO exploring demand response and reserve generation options

✅ Aim: maintain grid stability and avoid blackout risk

 

National Grid has warned that Britain’s electricity will be in short supply over the next few days after a string of unplanned power plant outages and unusually low wind speeds this week, as cheap wind power wanes across the system.

The electricity system operator said it will take action to “make sure there is enough generation” during the cold weather spell, including virtual power plants and other demand-side measures, to prevent a second major blackout in as many years.

“Unusually low wind output coinciding with a number of generator outages means the cushion of spare capacity we operate the system with has been reduced,” the company told its Twitter followers.

“We’re exploring measures and actions to make sure there is enough generation available to increase our buffer of capacity.”

A spokeswoman for National Grid said the latest electricity supply squeeze was not expected to be as severe as recorded last month, following reports that the government’s emergency energy plan was not going ahead, and added that the company did not expect to issue an official warning in the next 24 hours.

“We’re monitoring how the situation develops,” she said.

The warning is the second from the electricity system operator in recent weeks. In mid-September the company issued an official warning to the electricity market as peak power prices climbed, that its ‘buffer’ of power reserves had fallen below 500MW and it may need to call on more power plants to help prevent a blackout. The notice was later withdrawn.

Concerns over National Grid’s electricity supplies have been relatively rare in recent years. It was forced in November 2015 to ask businesses to cut their demand as a “last resort” measure to keep the lights on after a string of coal plant breakdowns.

But since then, National Grid’s greater challenge has been an oversupply of electricity, partly due to record wind generation, which has threatened to overwhelm the grid during times of low electricity demand.

National Grid has already spent almost £1bn on extra measures to prevent blackouts over the first half of the year by paying generators to produce less electricity during the coronavirus lockdown, as daily demand fell.

The company paid wind farms to turn off, and EDF Energy to halve the nuclear generation from its Sizewell B nuclear plant, to avoid overwhelming the grid when demand for electricity fell by almost a quarter from last year.

The electricity supply squeeze comes a little over a year after National Grid left large parts of England and Wales without electricity after the biggest blackout in a decade left a million homes in the dark. National Grid blamed a lightning strike for the widespread power failure.

Similar supply strains have recently caused power cuts in China, underscoring how weather and generation mix can trigger blackouts.

US Electricity Prices Rise Most in 41 Years as Inflation Endures

US Electricity Price Surge drives bills as BLS data show 15.8 percent jump; natural gas and coal costs escalate amid energy crisis, NYISO warns of wholesale prices and winter futures near $200 per MWh.

 

Key Points

A sharp rise in power bills driven by higher natural gas and coal costs and tighter wholesale markets.

✅ BLS reports electricity bills up 15.8% year over year

✅ Natural gas bills up 33% as fuel costs soar

✅ NYISO flags winter wholesale prices near $200/MWh

 

Electricity bills for US consumers jumped the most since 1981, gaining 15.8% from the same period a year ago, according to the US Bureau of Labor Statistics, and residential bills rose 5% in 2022 across the U.S.

Natural gas bills, which crept back up last month after dipping in July, surged 33% from the same month last year, labor data released Tuesday showed, as electricity and natural gas pricing dynamics continue to ripple through markets. Broader energy costs slipped for a second consecutive month because of lower gasoline and fuel oil prices. Even with that drop, total energy costs were still about 24% above August 2021 levels.

Electricity costs are relentlessly climbing because prices for the two biggest power-plant fuels -- natural gas and coal -- have surged in the last year as the US economy rebounds from the pandemic and as Russia’s war in Ukraine triggers an energy crisis in Europe, where German electricity prices nearly doubled over a year. Another factor is the hot and humid summer across most of the lower 48 states drove households and businesses to crank up air conditioners. Americans likely used a record amount of power in the third quarter, according to US Energy Information Administration projections, even as U.S. power demand is seen sliding 1% in 2023 on milder weather.

New York’s state grid operator warned of a “sharp rise in wholesale electric costs expected this winter” with spiking global demand for fossil fuels, lagging supply and instability from Russia’s war in Ukraine driving up oil and gas prices, with multiple energy-crisis impacts on U.S. electricity and gas still unfolding, according to a Tuesday report. Geopolitical factors are ultimately reflected in wholesale electricity prices and supply charges to consumer bills, the New York Independent System Operator said, and as utilities direct more spending to delivery rather than production.

Electricity price futures for this winter have increased fourfold from last year, and potential deep-freeze disruptions to the energy sector could add volatility, with prices averaging near $200 a megawatt-hour, the grid operator said. That has been driven by natural gas futures for the upcoming winter, which are more than double current prices to nearly $20 per million British thermal units.

Electricity and water do mix: How electric ships are clearing the air on the B.C. coast

Hybrid Electric Ships leverage marine batteries, LNG engines, and clean propulsion to cut emissions in shipping. From ferries to cargo vessels, electrification and sustainability meet IMO regulations, Corvus Energy systems, and dockside fast charging.

 

Key Points

Hybrid electric ships use batteries with diesel or LNG engines to cut fuel and emissions and meet stricter IMO rules.

✅ LNG or diesel gensets recharge marine battery packs.

✅ Cuts CO2, NOx, and particulate emissions in port and at sea.

✅ Complies with IMO standards; enables quiet, efficient operations.

 

The river is running strong and currents are swirling as the 150-metre-long Seaspan Reliant slides gently into place against its steel loading ramp on the shores of B.C.'s silty Fraser River.

The crew hustles to tie up the ship, and then begins offloading dozens of transport trucks that have been brought over from Vancouver Island.

While it looks like many vessels working the B.C. coast, below decks, the ship is very different. The Reliant is a hybrid, partly powered by electricity, and joins BC Ferries' hybrid ships in the region, the seagoing equivalent of a Toyota Prius.

Down below decks, Sean Puchalski walks past a whirring internal combustion motor that can run on either diesel or natural gas. He opens the door to a gleaming white room full of electrical cables and equipment racks along the walls.

"As with many modes of transportation, we're seeing electrification, from electric planes to ferries," said Puchalski, who works with Corvus Energy, a Richmond, B.C. company that builds large battery systems for the marine industry.

In this case, the batteries are recharged by large engines burning natural gas.

"It's definitely the way of the future," said Puchalski.

The 10-year-old company's battery system is now in use on 200 vessels around the world. Business has spiked recently, driven by the need to reduce emissions, and by landmark projects such as battery-electric high-speed ferries taking shape in the U.S.

"When you're building a new vessel, you want it to last for, say, 30 years. You don't want to adopt a technology that's on the margins in terms of obsolescence," said Puchalski. "You want to build it to be future-proof."

 

Dirty ships

For years, the shipping industry has been criticized for being slow to clean up its act. Most ships use heavy fuel oil, a cheap, viscous form of petroleum that produces immense exhaust. According to the European Commission, shipping currently pumps out about 940 million tonnes of CO2 each year, nearly three per cent of the global total.

That share is expected to climb even higher as other sectors reduce emissions.

When it comes to electric ships, Scandinavia is leading the world. Several of the region's car and passenger ferries are completely battery powered — recharged at the dock by relatively clean hydro power, and projects such as Kootenay Lake's electric-ready ferry show similar progress in Canada.

 

Tougher regulations and retailer pressure

The push for cleaner alternatives is being partly driven by worldwide regulations, with international shipping regulators bringing in tougher emission standards after a decade of talk and study, while financing initiatives are helping B.C. electric ferries scale up.

At the same time, pressure is building from customers, such as Mountain Equipment Co-op, which closely tracks its environmental footprint. Kevin Lee, who heads MEC's supply chain, said large companies are realizing they are accountable for their contributions to climate change, from the factory to the retail floor.

"You're hearing more companies build it into their DNA in terms of how they do business, and that's cool to see," said Lee. "It's not just MEC anymore trying to do this, there's a lot more partners out there."

In the global race to cut emissions, all kinds of options are on the table for ships, including giant kites being tested to harvest wind power at sea, and ports piloting hydrogen-powered cranes to cut dockside emissions.

Modern versions of sailing ships are also being examined to haul cargo with minimal fuel consumption.

But in practical terms, hybrids and, in the future, pure electrics are likely to play a larger role in keeping the propellers turning along Canada's coast, with neighboring fleets like Washington State Ferries' upgrade underscoring the shift.

Electricity prices in Germany nearly doubled in a year

Germany Energy Price Hikes are driving electricity tariffs, gas prices, and heating costs higher as wholesale markets surge after the Ukraine invasion; households face inflationary pressure despite relief measures and a renewables levy cut.

 

Key Points

Germany Energy Price Hikes reflect surging power and gas tariffs from wholesale spikes, prompting relief measures.

✅ Electricity tariffs to rise 19.5% in Apr-Jun

✅ Gas tariffs up 42.3%; heating and fuel costs soar

✅ Renewables levy ends July; saves €6.6 billion yearly

 

Record prices for electricity and gas in Germany will continue to rise in the coming months, the dpa agency, citing estimates from the consumer portal Verivox.

According to him, electricity suppliers and local utilities, in whose area of ​​responsibility there are 13 million households, made an announcement of tariff increases in April, May and June by 19.5%. Gas tariffs increased by an average of 42.3%.

According to Verivox, electricity prices in Germany have approximately doubled over the year - a pattern seen as European electricity prices rose more than double the EU average - if previously a household with a consumption of 4,000 kWh paid 1,171 euros a year, now the amount has risen to 1,737 euros. Gas prices have risen even more, though European gas prices later returned to pre-Ukraine war levels: last year, a household with a consumption of 20,000 kWh paid 1,184 euros in annual terms, and now it is 2,787 euros. 

Energy costs for the average German household are 52 percent higher than a year ago, adding to EU inflation pressures, according to energy contract sales website Check24. In a press release, the company said the wholesale electricity price was at €122.93 per megawatt-hour in February 2022, compared to €49 this time last year, while in the United States US electricity prices climbed at the fastest pace in 41 years. In addition, electricity prices on the power exchange haven been rising rapidly since Russian troops invaded Ukraine, comparison portal Strom Report said. Costs for heating rose the most, triggered by the high gas price (105 euros per megawatt-hour on the wholesale market) and around 100 USD per barrel of oil – its highest price since 2014. Driving also became more expensive with costs for petrol up 25 percent and diesel 30 percent, Check24 said.

The German government has decided on relief measures for low-income households, including a 200 billion euro energy shield, in response to high consumer energy costs. In July, it will abolish the renewables levy on the power price, saving consumers around €6.6 billion annually. In a reform proposal released this week, the ministry for economy and climate also detailed how it will legally oblige power suppliers to reduce their power bills when the levy is abolished.
