Minnesota-based energy technology company Independent Natural Resources Inc. (INRI) announced it is conducting a three-month demonstration of its SEADOG technology in the Gulf of Mexico, off of Galveston, Texas, under supervision and documentation from the Texas A&M University at Galveston Marine Engineering Technology Department.

The versatile SEADOG Pump system can provide abundant fresh water when combined with desalination and produce clean renewable energy when combined with a variety of turbine-driven systems.

INRI, formed in January of 2002 by CEO Mark A. Thomas, developed and acquired the SEADOG Pump technology from its inventor, Kenneth W. Welch, Jr., and co-inventors Curtis and Harold Rothi.

SEADOG captures ocean-wave energy from swells or waves to pump large volumes of seawater to shore-based storage or sea-based platform systems while consuming no fuel. February 2007 ocean trial testing off the coast of Freeport/Surfside Beach, Texas, validated the results of several years of concepts and planning, showing the company's SEADOG Pump wave-pump technology as a viable means of harvesting renewable power from ocean waves.

"As a wave energy collector, its simplicity, apparent efficiency and effectiveness is commendable and can be placed among the best available wave energy collectors to date," said Frank Warnakulasuriya, Ph.D., assistant head of the department, Marine Engineering Technology, Texas A&M University at Galveston.

The size, configuration and pumping capacity of SEADOG varies depending on the wave regime, height and frequency. During testing off of the coast of Surfside Beach/Freeport, Texas, a single SEADOG Pump has experienced modest waves from 6 inches to 8 feet and has consistently pumped a range of 2,000 to 50,000 gallons of seawater per day.

"Our initial sea trial in the Gulf of Mexico exceeded our expectations, and we're excited to partner with Texas A&M University to supervise and document SEADOG Pump performance and utilize their contribution toward final design and material specification," said Mark A. Thomas, CEO, INRI. "Going forward, we're seeking actual ocean environments where we can place a demonstration wave-farm test field involving 9 to 200 SEADOG Pump wave pumps. If the wave pump continues to perform as well as our sea trials have shown, we believe it has the potential to be a breakthrough for global energy production." Wave farms may range from 50 to 80,000 pumps and exist in sea states from 6 inches to 80 foot seas.

Most wave-energy technologies involve off-shore electrical generation requiring the transmission of power to shore-based electricity grids. These technologies involve costly, complex equipment that is sensitive to corrosive seawater and has the intermittency issues similar to wind and solar. SEADOG uses a different approach with a simple pump design with few moving parts and no electronics.

To generate electricity, the SEADOG Pump ocean-wave pump captures energy from ocean swells or waves to pump seawater to a land-based holding area, where the water can be returned to the ocean through turbines, thereby producing inexpensive, renewable electricity.

Preliminary estimates based on SEADOG sea trial results suggest that a 1-square-mile field of SEADOG Pumps could generate anywhere from 50 megawatts to more than 1,500 megawatts of electricity on average, depending on the wave regime, enough power to run 67,000 to more than 2,000,000 homes.

The device pumps water to shore-based storage or sea-based platform systems, and it can store salt water or desalinated fresh water in the form of potential energy to generate power on demand, even if the current wave regime during a particular period is too low to generate power.

Customers on the hook for $5.5 billion in deferred BC Hydro operating costs: report

BC Hydro Deferred Regulatory Assets detail $5.5 billion in costs under rate-regulated accounting, to be recovered from ratepayers, highlighting B.C. Utilities Commission oversight, audit scrutiny, financial reporting impacts, and public utility governance.

 

Key Points

BC Hydro defers costs as regulatory assets to recover from ratepayers, influencing rates and financial reporting.

✅ $5.5B in deferred costs recorded as net regulatory assets

✅ Rate impacts tied to B.C. Utilities Commission oversight

✅ Auditor General to assess accounting and governance

 

Auditor General Carol Bellringer says BC Hydro has deferred $5.5 billion in expenses that it plans to recover from ratepayers in the future, as rates to rise by 3.75% over two years.

Bellringer focuses on the deferred expenses in a report on the public utility's use of rate-regulated accounting to control electricity rates for customers.

"As of March 31, 2018, BC Hydro reported a total net regulatory asset of $5.455 billion, which is what ratepayers owe," says the report. "BC Hydro expects to recover this from ratepayers in the future. For BC Hydro, this is an asset. For ratepayers, this is a debt."

She says rate-regulated accounting is used widely across North America, but cautions that Hydro has largely overridden the role of the independent B.C. Utilities Commission to regulate rates.

"We think it's important for the people of B.C. and our members of the legislative assembly to better understand rate-regulated accounting in order to appreciate the impact it has on the bottom line for BC Hydro, for government as a whole, for ratepayers and for taxpayers, especially following a three per cent rate increase in April 2018," Bellringer said in a conference call with reporters.

Last June, the B.C. government launched a two-phase review of BC Hydro to find cost savings and look at the direction of the Crown utility, amid calls for change from advocates.

The review came shortly after a planned government rate freeze was overturned by the utilities commission, which resulted in a three per cent rate increase in April 2018.

A statement by BC Hydro and the government says a key objective of the review due this month is to enhance the regulatory oversight of the commission.

Bellringer's office will become BC Hydro's auditor next year — and will be assessing the impact of regulation on the utility's financial reporting.

"It is a complex area and confidence in the regulatory system is critical to protect the public interest," wrote Bellringer.

Why electric buses haven't taken over the world—yet

Electric Buses reduce urban emissions and noise, but require charging infrastructure, grid upgrades, and depot redesigns; they offer lower operating costs and simpler maintenance, with range limits influencing routes, schedules, and on-route fast charging.

 

Key Points

Battery-electric buses cut emissions and noise while lowering operating and maintenance costs for transit agencies.

✅ Lower emissions, noise; improved rider experience

✅ Requires charging, grid upgrades, depot redesigns

✅ Range limits affect routes; on-route fast charging helps

 

In lots of ways, the electric bus feels like a technology whose time has come. Transportation is responsible for about a quarter of global emissions, and those emissions are growing faster than in any other sector. While buses are just a small slice of the worldwide vehicle fleet, they have an outsize effect on the environment. That’s partly because they’re so dirty—one Bogotá bus fleet made up just 5 percent of the city’s total vehicles, but a quarter of its CO2, 40 percent of nitrogen oxide, and more than half of all its particulate matter vehicle emissions. And because buses operate exactly where the people are concentrated, we feel the effects that much more acutely.

Enter the electric bus. Depending on the “cleanliness” of the electric grid into which they’re plugged, e-buses are much better for the environment. They’re also just straight up nicer to be around: less vibration, less noise, zero exhaust. Plus, in the long term, e-buses have lower operating costs, and related efforts like US school bus electrification are gathering pace too.

So it makes sense that global e-bus sales increased by 32 percent last year, according to a report from Bloomberg New Energy Finance, as the age of electric cars accelerates across markets worldwide. “You look across the electrification of cars, trucks—it’s buses that are leading this revolution,” says David Warren, the director of sustainable transportation at bus manufacturer New Flyer.

Today, about 17 percent of the world’s buses are electric—425,000 in total. But 99 percent of them are in China, where a national mandate promotes all sorts of electric vehicles. In North America, a few cities have bought a few electric buses, or at least run limited pilots, to test the concept out, and early deployments like Edmonton's first e-bus offer useful lessons as systems ramp up. California has even mandated that by 2029 all buses purchased by its mass transit agencies be zero-emission.

But given all the benefits of e-buses, why aren’t there more? And why aren’t they everywhere?

“We want to be responsive, we want to be innovative, we want to pilot new technologies and we’re committed to doing so as an agency,” says Becky Collins, the manager of corporate initiative at the Southeastern Pennsylvania Transportation Authority, which is currently on its second e-bus pilot program. “But if the diesel bus was a first-generation car phone, we’re verging on smartphone territory right now. It’s not as simple as just flipping a switch.”

One reason is trepidation about the actual electric vehicle. Some of the major bus manufacturers are still getting over their skis, production-wise. During early tests in places like Belo Horizonte, Brazil, e-buses had trouble getting over steep hills with full passenger loads. Albuquerque, New Mexico, canceled a 15-bus deal with the Chinese manufacturer BYD after finding equipment problems during testing. (The city also sued). Today’s buses get around 225 miles per charge, depending on topography and weather conditions, which means they have to re-up about once a day on a shorter route in a dense city. That’s an issue in a lot of places.

If you want to buy an electric bus, you need to buy into an entire electric bus system. The vehicle is just the start.

The number one thing people seem to forget about electric buses is that they need to get charged, and emerging projects such as a bus depot charging hub illustrate how infrastructure can scale. “We talk to many different organizations that get so fixated on the vehicles,” says Camron Gorguinpour, the global senior manager for the electric vehicles at the World Resources Institute, a research organization, which last month released twin reports on electric bus adoption. “The actual charging stations get lost in the mix.”

But charging stations are expensive—about $50,000 for your standard depot-based one. On-route charging stations, an appealing option for longer bus routes, can be two or three times that. And that’s not even counting construction costs. Or the cost of new land: In densely packed urban centers, movements inside bus depots can be tightly orchestrated to accommodate parking and fueling. New electric bus infrastructure means rethinking limited space, and operators can look to Toronto's TTC e-bus fleet for practical lessons on depot design. And it’s a particular pain when agencies are transitioning between diesel and electric buses. “The big issue is just maintaining two sets of fueling infrastructure,” says Hanjiro Ambrose, a doctoral student at UC Davis who studies transportation technology and policy.

“We talk to many different organizations that get so fixated on the vehicles. The actual charging stations get lost in the mix as the American EV boom gathers pace across sectors.”

Then agencies also have to get the actual electricity to their charging stations. This involves lengthy conversations with utilities about grid upgrades, rethinking how systems are wired, occasionally building new substations, and, sometimes, cutting deals on electric output, since electric truck fleets will also strain power systems in parallel. Because an entirely electrified bus fleet? It’s a lot to charge. Warren, the New Flyer executive, estimates it could take 150 megawatt-hours of electricity to keep a 300-bus depot charged up throughout the day. Your typical American household, by contrast, consumes 7 percent of that—per year. “That’s a lot of work by the utility company,” says Warren.

For cities outside of China—many of them still testing out electric buses and figuring out how they fit into their larger fleets—learning about what it takes to run one is part of the process. This, of course, takes money. It also takes time. Optimists say e-buses are more of a question of when than if. Bloomberg New Energy Finance projects that just under 60 percent of all fleet buses will be electric by 2040, compared to under 40 percent of commercial vans and 30 percent of passenger vehicles.

Which means, of course, that the work has just started. “With new technology, it always feels great when it shows up,” says Ambrose. “You really hope that first mile is beautiful, because the shine will come off. That’s always true.”

Hydro One extends ban on electricity disconnections until further notice

Hydro One Disconnection Ban Extension keeps Ontario electricity customers connected during COVID-19, extending the moratorium on power shutoffs and expanding financial relief programs amid ongoing pandemic restrictions and persistent hot weather across the province.

 

Key Points

An open-ended Ontario utility moratorium preventing residential power shutoffs and offering bill relief during COVID-19.

✅ No residential disconnections until further notice

✅ Extended bill assistance and flexible payment options

✅ Response to COVID-19 restrictions and extreme heat

 

Ontario's primary electricity provider says it's extending a ban on disconnecting homes from the power grid until further notice.

Hydro One first issued the ban towards the beginning of the province's COVID-19 outbreak, saying self-isolating customers needed to be able to rely on electricity while they were kept at home during the pandemic.

A spokesman for the utility says the ban was initially set to expire at the end of July, but has now been extended in a manner similar to winter disconnection bans without a fixed end-date.

Hydro One says the move is necessary given the ongoing restrictions posed by the pandemic, and notes it has supported provincial COVID-19 efforts in recent months, as well as persistent hot weather across much of the province.

It says it's also planning to extend a financial relief program to help customers struggling to pay their hydro bills, reflecting demand for more choice and flexibility among ratepayers.

The province also extended off-peak electricity rates to provide relief for families, small businesses and farms during this period.

Ford's Washington Meeting: Energy Tariffs and Trade Tensions with U.S

Ontario-U.S. Energy Tariff Dispute highlights cross-border trade tensions, retaliatory tariffs, export surcharges, and White House negotiations as Doug Ford meets U.S. officials to de-escalate pressure over steel, aluminum, and energy supplies.

 

Key Points

A trade standoff over energy exports and tariffs, sparked by Ontario's surcharge and U.S. duties on steel and aluminum.

✅ 25% Ontario energy surcharge paused before White House talks

✅ U.S. steel and aluminum tariffs reduced from 50% to 25%

✅ Potential energy supply cutoff remains leverage in negotiations

 

Ontario Premier Doug Ford's recent high-stakes diplomatic trip to Washington, D.C., underscores the delicate trade tensions between Canada and the United States, particularly concerning energy exports and Canada's electricity exports across the border. Ford's potential use of tariffs or even halting U.S. energy supplies, amid Ontario's energy independence considerations, remains a powerful leverage tool, one that could either de-escalate or intensify the ongoing trade conflict between the two neighboring nations.

The meeting in Washington follows a turbulent series of events that began with Ontario's imposition of a 25% surcharge on energy exports to the U.S. This move came in retaliation to what Ontario perceived as unfair treatment in trade agreements, a step that aligned with Canadian support for tariffs at the time. In response, U.S. President Donald Trump's administration threatened its own set of tariffs, specifically targeting Canadian steel and aluminum, which further escalated tensions. U.S. officials labeled Ford's threat to cut off U.S. electricity exports and energy supplies as "egregious and insulting," warning of significant economic retaliation.

However, shortly after these heated exchanges, Trump’s commerce secretary, Howard Lutnick, extended an invitation to Ford for a direct meeting at the White House. Ford described this gesture as an "olive branch," signaling a potential de-escalation of the dispute. In the lead-up to this diplomatic encounter, Ford agreed to pause the energy surcharge, allowing the meeting to proceed, amid concerns tariffs could spike NY energy prices, without further escalating the crisis. Trump's administration responded by lowering its proposed 50% tariff on Canadian steel and aluminum to a more manageable 25%.

The outcome of the meeting, which is set to address these critical issues, could have lasting implications for trade relations between Canada and the U.S. If Ford and Lutnick can reach an agreement, the potential for tariff imposition on energy exports, though experts advise against cutting Quebec's energy exports due to broader risks, could be resolved. However, if the talks fail, it is likely that both countries could face further retaliatory measures, compounding the economic strain on both sides.

As Canada and the U.S. continue to navigate these complex issues, where support for Canadian energy projects has risen, the outcome of Ford's meeting with Lutnick will be closely watched, as it could either defuse the tensions or set the stage for a prolonged trade battle.
