A Toronto company that had proposed a 420-mile underwater electric-transmission cable from Canada, a portion of which would have gone under Long Island Sound to Bridgeport, is scrapping its plans for the Connecticut leg of the project.

Transmission Developers Inc. announced it is abandoning the portion of the route that would have gone from New York City to Bridgeport Harbor.

The announcement came from Donald Jessome, president and chief executive officer of TDI, at City Hall during the first of seven hearings on the projectÂ’s potential environmental impact.

“The market has spoken,” Jessome said, explaining that the power generators that will pay to build the so-called Champlain Hudson Power Express found selling their electricity in the New York City marketplace more lucrative than selling it in Connecticut.

Scrapping the Connecticut leg of the project will reduce the cost of the project from $3.8 billion to $1.9 billion, the length of the line from 420 miles to 355, and the amount of electricity transported on it from 2,000 megawatts to 1,000 megawatts, Jessome said.

But the timetable for completion, he said, remains some time in 2015.

The project will begin in southern Quebec and enter the United States with high-voltage direct-current cables buried underneath the Richelieu River, which flows from the north end of Lake Champlain. The cables will be buried along the entire length of Lake Champlain.

A portion of the cable in upstate New York, near Albany, will be buried along a railroad right of way, before going back underwater in the Hudson River. With the Connecticut leg of the project being eliminated, the line will end in Yonkers, N.Y.

The hearing on the project, which was conducted by the U.S. Department of Energy, was attended by fewer than a dozen people.

No one spoke during the public comment portion of the meeting.

Because the line is crossing into the United States from Canada, it needs a special permit, said Jerry Pell, an environmental scientist with the Department of Energy, who was chairman of the hearing.

A representative of Save the Sound, a program of the Connecticut Fund for the Environment, said TDIÂ’s decision illustrates the need for a two-state body charged with coordinating long-term planning and protection of Long Island Sound.

“This project is yet another in a long line of projects.... This was the seventh Long Island Sound energy proposal in fewer than 10 years,” said Leah Schmalz, director of legislative and legal affairs for Save the Sound.

“While, thankfully, we may never need detailed investigation of an environmental-impact statement, nor the rigorous inquiry of independent scientists on the Sound portion of the Champlain Hudson project, we can be sure that we will face another... energy inquiry in future years.”

Learn how fees and usage impacts your electricity bill in new online CER tool

CER Interactive Electricity Bill Tool compares provincial electricity prices, fees, taxes, and usage. Explore household appliance costs, hydroelectric generation, and consumption trends across Canada with interactive calculators and a province-by-province breakdown.

 

Key Points

An online CER report with calculators comparing electricity prices, fees, and usage to explain household energy costs.

✅ Province-by-province bill, price, and consumption comparison

✅ Calculator for appliance and electronics energy costs

✅ Explains fees, taxes, regulation, and generation sources

 

Canadians have a new way to assess their electricity bill in a new, interactive online report released by the Canada Energy Regulator (CER).

The report titled What is in a residential electricity bill? features a province-to-province comparison of electricity bills, generation and consumption. It also explains electricity prices across the country, including how Calgary electricity prices have changed, allowing people to understand why costs vary depending on location, fees, regulation and taxes.  

Learn how fees and usage impacts your electricity bill in new online CER tool
Interactive tools allow people to calculate the cost of household appliances and electronic use for each province and territory, and to understand how Ontario rate increases may affect monthly bills. For example, an individual can use the tools to find out that leaving a TV on for 24-hours in Quebec costs $5.25 per month, while that same TV on for a whole day would cost $12.29 per month in Saskatchewan, $20.49 per month in the Northwest Territories, and $15.30 per month in Nova Scotia.

How Canadians use energy varies as much as how provinces and territories produce it, especially in regions like Nunavut where unique conditions influence costs. Millions of Canadians rely on electricity to power their household appliances, charge their electronics, and heat their homes. Provinces with abundant hydro-electric resources like Quebec, B.C., Manitoba, and Newfoundland and Labrador use electricity for home heating and tend to consume the most electricity.

By gathering data from various sources, this report is the first Canadian publication that features interactive tools to allow for a province-by-province comparison of electricity bills while highlighting different elements within an electricity bill, a helpful context as Canada faces a critical supply crunch in the years ahead.

The CER monitors energy markets and assesses Canadian energy requirements and trends, including clean electricity regulations developments that shape pricing. This report is part of a portfolio of publications on energy supply, demand and infrastructure that the CER publishes regularly as part of its ongoing market monitoring.

"No matter where you go in the country, Canadians want to know how much they pay for power and why, especially amid price spikes in Alberta this year," says lead author Colette Craig. "This innovative, interactive report really explains electricity bills to help everyone understand electricity pricing and consumption across Canada."

Quick Facts

  • Quebec ranks first in electricity consumption per capita at 21.0 MW.h, followed by Saskatchewan at 20.0 MW.h, Newfoundland and Labrador at 19.3 MW.h.
  • About 95% of Quebec's electricity is produced from hydroelectricity.
  • Provinces that use electricity for home heating tend to consume the most electricity.
  • Canada's largest consuming sector for electricity was industrial at 238 TW.h. The residential and commercial sectors consumed 168 TW.h and 126 TW.h, respectively.
  • In 2018, Canada produced 647.7 terawatt hours (TW.h) of electricity. More than half of the electricity in Canada (61%) is generated from hydro sources. The remainder is produced from a variety of sources, such as fossil fuels (natural gas and petroleum), nuclear, wind, coal, biomass, solar.
  • Canada is a net exporter of electricity. In 2019, net exports to the U.S. electricity market totaled 47.0 TW.h.
  • The total value of Canada's electricity exports was $2.5 billion Canadian dollars and the value of imports was $0.6 billion Canadian dollars, resulting in 2019 net exports of $1.9 billion.
  • All regions in Canada are reflected in this report but it does not include data that reflects the COVID-19 lockdown and its effects on residential electricity bills.

N.S. approves new attempt to harness Bay of Fundy's powerful tides

Bay of Fundy Tidal Energy advances as Nova Scotia permits Jupiter Hydro to test floating barge platforms with helical turbines in Minas Passage, supporting renewable power, grid-ready pilots, and green jobs in rural communities.

 

Key Points

A Nova Scotia tidal energy project using helical turbines to generate clean power and create local jobs.

✅ Permits enable 1-2 MW prototypes near Minas Passage

✅ Floating barge platforms with patented helical turbines

✅ PPA at $0.50/kWh with Nova Scotia Power

 

An Alberta-based company has been granted permission to try to harness electricity from the powerful tides of the Bay of Fundy.

Nova Scotia has issued two renewable energy permits to Jupiter Hydro.

Backers have long touted the massive energy potential of Fundy's tides -- they are among the world's most powerful -- but large-scale commercial efforts to harness them have borne little fruit so far, even as a Scottish tidal project recently generated enough power to supply nearly 4,000 homes elsewhere.

The Jupiter application says it will use three "floating barge type platforms" carrying its patented technology. The company says it uses helical turbines mounted as if they were outboard motors.

"Having another company test their technology in the Bay of Fundy shows that this early-stage industry continues to grow and create green jobs in our rural communities," Energy and Mines Minister Derek Mombourquette said in a statement.

The first permit allows the company to test a one-megawatt prototype that is not connected to the electricity grid.

The second -- a five-year permit for up to two megawatts -- is renewable if the company meets performance standards, environmental requirements and community engagement conditions.

Mombourquette also authorized a power purchase agreement that allows the company to sell the electricity it generates to the Nova Scotia grid through Nova Scotia Power for 50 cents per kilowatt hour.

On its web site, Jupiter says it believes its approach "will prove to be the most cost effective marine energy conversion technology in the world," even as other regional utilities consider initiatives like NB Power's Belledune concept for turning seawater into electricity.

The one megawatt unit would have screws which are about 5.5 metres in diameter.

The project is required to obtain all other necessary approvals, permits and authorizations.

It will be located near the Fundy Ocean Research Center for Energy in the Minas Passage and will use existing electricity grid connections.

A study commissioned by the Offshore Energy Research Association of Nova Scotia says by 2040, the tidal energy industry could contribute up to $1.7 billion to Nova Scotia's gross domestic product and create up to 22,000 full-time jobs, a transition that some argue should be planned by an independent body to ensure reliability.

Last month, Nova Scotia Power said it now generates 30 per cent of its power from renewables, as the province moves to increase wind and solar projects after abandoning the Atlantic Loop.

The utility says 18 per cent came from wind turbines, nine per cent from hydroelectric and tidal turbines and three per cent by burning biomass across its fleet.

However, over half of the province's electrical generation still comes from the burning of coal or petroleum coke, even as environmental advocates push to reduce biomass use in the mix. Another 13 per cent come from burning natural gas and five per cent from imports.

Starting Texas Schools After Labor Day: Power Grid and Cost Benefits?

Texas After-Labor Day School Start could ease ERCOT's power grid strain by shifting peak demand, lowering air-conditioning loads in schools, improving grid reliability, reducing electricity costs, and curbing emissions during extreme heat the summer months.

 

Key Points

A proposed calendar shift to start school after Labor Day to lower ERCOT peak demand, costs, and grid risk.

✅ Cuts school HVAC loads during peak summer heat

✅ Lowers costly peaker plant use and electricity rates

✅ Requires calendar changes, testing and activities shifts

 

As Texas faces increasing demands on its power grid, a new proposal is gaining traction: starting the school year after Labor Day. This idea, reported by the Dallas News, suggests that delaying the start of the academic year could help alleviate some of the pressure on the state’s electricity grid during the peak summer months, potentially leading to both grid stability and financial savings. Here’s an in-depth look at how this proposed change could impact Texas’s energy landscape and education system.

The Context of Power Grid Strain

Texas's power grid, operated by the Electric Reliability Council of Texas (ERCOT), has faced significant challenges in recent years. Extreme weather events, record-breaking temperatures, and high energy demand have strained the grid, and some analyses argue that climate change, not demand is the biggest challenge today, leading to concerns about reliability and stability. The summer months are particularly taxing, as the demand for air conditioning surges, often pushing the grid to its limits.

In this context, the idea of adjusting the school calendar to start after Labor Day has been proposed as a potential strategy to help manage electricity demand. By delaying the start of school, proponents argue that it could reduce the load on the power grid during peak usage periods, thereby easing some of the stress on energy resources.

Potential Benefits for the Power Grid

The concept of delaying the school year is rooted in the potential benefits for the power grid. During the hottest months of summer, the demand for electricity often spikes as families use air conditioning to stay cool, and utilities warn to prepare for blackouts as summer takes hold. School buildings, typically large and energy-intensive facilities, contribute significantly to this demand when they are in operation.

Starting school later could help reduce this peak demand, as schools would be closed during the hottest months when the grid is under the most pressure. This reduction in demand could help prevent grid overloads and reduce the risk of power outages, at a time when longer, more frequent outages are afflicting the U.S. power grid, ultimately contributing to a more stable and reliable electricity supply.

Additionally, a decrease in peak demand could help lower electricity costs. Power plants, particularly those that are less efficient and more expensive to operate, are often brought online during periods of high demand. By reducing the peak load, the state could potentially minimize the need for these costly power sources, leading to lower overall energy costs.

Financial and Environmental Considerations

The financial implications of starting school after Labor Day extend beyond just the power grid. By reducing energy consumption during peak periods, the state could see significant savings on electricity costs. This, in turn, could lead to lower utility bills for schools, businesses, and residents alike, a meaningful relief as millions risk electricity shut-offs during summer heat.

Moreover, reducing the demand for electricity from fossil fuel sources can have positive environmental impacts. Lower peak demand may reduce the reliance on less environmentally friendly energy sources, and aligns with calls to invest in a smarter electricity infrastructure nationwide, thereby decreasing greenhouse gas emissions and contributing to overall environmental sustainability.

Challenges and Trade-offs

While the proposal offers potential benefits, it also comes with challenges and trade-offs. Adjusting the school calendar would require significant changes to the academic schedule, potentially affecting extracurricular activities, summer programs, and family plans, and comparisons to California's reliability challenges underscore the complexity. Additionally, there could be resistance from various stakeholders, including parents, educators, and students, who are accustomed to the current school calendar.

There are also logistical considerations to address, such as how a delayed start might impact standardized testing schedules and the academic calendar for higher education institutions. These factors would need to be carefully evaluated to ensure that the proposed changes do not adversely affect educational outcomes or create unintended consequences.

Looking Ahead

The idea of starting Texas schools after Labor Day represents an innovative approach to addressing the challenges facing the state’s power grid. By potentially reducing peak demand and lowering energy costs, and alongside efforts to connect Texas's grid to the rest of the nation, this proposal could contribute to greater grid stability and financial savings. However, careful consideration and planning will be essential to navigate the complexities of altering the school calendar and to ensure that the benefits outweigh the challenges.

As Texas continues to explore solutions for managing its power grid and energy resources, the proposal to shift the school year schedule provides an intriguing possibility. It reflects a broader trend of seeking creative and multifaceted approaches to balancing energy demand, environmental sustainability, and public needs.

In conclusion, starting schools after Labor Day could offer tangible benefits for Texas’s power grid and financial well-being. As discussions on this proposal advance, it will be important to weigh all factors and engage stakeholders to ensure a successful and equitable implementation.

Some in Tennessee could be without power for weeks after strong storms hit

Middle Tennessee Power Outages disrupt 100,000+ customers as severe thunderstorms, straight-line winds, downed trees, and debris challenge Nashville crews, slow restoration amid COVID-19, and threaten more hail, flash flooding, and damaging gusts.

 

Key Points

Blackouts across Nashville after severe storms and winds, leaving customers without power and facing restoration delays.

✅ Straight-line winds 60-80 mph toppled trees and power lines

✅ 130,000+ customers impacted; some outages may last 1-2 weeks

✅ Restoration slowed by debris, COVID-19 protocols, and new storms

 

Some middle Tennessee residents could be without electricity for up to two weeks after strong thunderstorms swept through the area Sunday, knocking out power for more than 100,000 customers, a scale comparable to Los Angeles outages after a station fire.

"Straight line winds as high as 60-80 miles per hour knocked down trees, power lines and power polls, interrupting power to 130,000 of our 400,000+ customers," Nashville Electric said in a statement Monday. The utility said the outage was one of the largest on record, though Carolina power outages recently left a quarter-million without power as well.

"Restoration times will depend on individual circumstances. In some cases, power could be out for a week or two" as challenges related to coronavirus and the need for utilities adapt to climate change complicated crews' responses and more storms were expected, the statement said. "This is unfortunate timing on the heels of a tornado and as we deal with battling COVID-19."

Metropolitan Nashville and Davidson County Mayor John Cooper also noted that the power outages were especially inconvenient, a challenge similar to Hong Kong families without power during Typhoon Mangkhut, as people were largely staying home to slow the spread of coronavirus. He also pointed out that the storms came on the two month anniversary of the Nashville tornado that left at least two dozen people dead.

"Crews are working diligently to restore power and clear any debris in neighborhoods," Cooper said.

He said that no fatalities were reported in the county but sent condolences to Spring Hill, whose police department reported that firefighter Mitchell Earwood died during the storm due to "a tragic weather-related incident" while at his home and off duty. He had served with the fire department for 10 years.

The Metro Nashville Department of Public Works said it received reports of more than 80 downed trees in Davidson County.

Officials also warn that copper theft can be deadly when electrical infrastructure is damaged after storms.

The National Weather Service Nashville said a 72 mph wind gust was measured at Nashville International Airport — the fifth fastest on record.

The weather service warned that strong storms with winds of up to 75 mph, large hail, record-long lightning bolt potential seen in the U.S., and isolated flash flooding could hit middle Tennessee again Monday afternoon and night.

"Treat Severe Thunderstorm Warnings the same way you would Tornado Warnings and review storm safety tips before you JUST TAKE SHELTER," the NWS instructs. "70 mph is 70 mph whether it's spinning around in a circle or blowing in a straight line."

Iceland Cryptocurrency mining uses so much energy, electricity may run out

Iceland Bitcoin Mining Energy Shortage highlights surging cryptocurrency and blockchain data center electricity demand, as hydroelectric and geothermal power strain to cool servers, stabilize grid, and meet rapid mining farm growth amid Arctic-friendly conditions.

 

Key Points

Crypto mining data centers in Iceland are outpacing renewable power, straining the grid and exceeding residential electricity demand.

✅ Hydroelectric and geothermal capacity nearing allocation limits

✅ Cooling-friendly climate draws energy-hungry mining farms

✅ Grid planning and regulation lag rapid data center growth

 

The value of bitcoin may have stumbled in recent months, but in Iceland it has known only one direction so far: upward. The stunning success of cryptocurrencies around the globe has had a more unexpected repercussion on the island of 340,000 people: It could soon result in an energy shortage in the middle of the Atlantic Ocean.

As Iceland has become one of the world's prime locations for energy-hungry cryptocurrency servers — something analysts describe as a 21st-century gold-rush equivalent — the industry’s electricity demands have skyrocketed, too. For the first time, they now exceed Icelanders’ own private energy consumption, and energy producers fear that they won’t be able to keep up with rising demand if Iceland continues to attract new companies bidding on the success of cryptocurrencies, a concern echoed by policy moves like Russia's proposed mining ban amid electricity deficits.

Companies have flooded Iceland with requests to open new data centers to “mine” cryptocurrencies in recent months, even as concerns mount that the country may have to slow down investments amid an increasingly stretched electricity generation capacity, a dynamic seen in BC Hydro's suspension of new crypto connections in Canada.

“There was a lot of talk about data centers in Iceland about five years ago, but it was a slow start,” Johann Snorri Sigurbergsson, a spokesman for Icelandic energy producer HS Orka, told The Washington Post. “But six months ago, interest suddenly began to spike. And over the last three months, we have received about one call per day from foreign companies interested in setting up projects here.”

“If all these projects are realized, we won’t have enough energy for it,” Sigurbergsson said.

Every cryptocurrency in the world relies on a “blockchain” platform, which is needed to trade with digital currencies. Tracking and verifying a transaction on such a platform is like solving a puzzle because networks are often decentralized, and there is no single authority in charge of monitoring payments. As a result, a transaction involves an immense number of mathematical calculations, which in turn occupy vast computer server capacity. And that requires a lot of electricity, as analyses of bitcoin's energy use indicate worldwide.

The bitcoin rush may have come as a surprise to locals in sleepy Icelandic towns that are suddenly bustling with cryptocurrency technicians, but there’s a simple explanation. “The economics of bitcoin mining mean that most miners need access to reliable and very cheap power on the order of 2 or 3 cents per kilowatt hour. As a result, a lot are located near sources of hydro power, where it’s cheap,” Sam Hartnett, an associate at the nonprofit energy research and consulting group Rocky Mountain Institute, told the Washington Post.

Top financial regulators briefed a Senate panel on Feb. 6 about their work with cryptocurrencies like Bitcoin, and the risks to potential investors. (Reuters)

Located in the middle of the Atlantic Ocean and famous for its hot springs and mighty rivers, Iceland produces about 80 percent of its energy in hydroelectric power stations, compared with about 6 percent in the United States, and innovations such as underwater kites illustrate novel ways to harness marine energy. That and the cold climate make it a perfect location for new data-mining centers filled with servers in danger of overheating.

Those conditions have attracted scores of foreign companies to the remote location, including Germany's Genesis Mining, which moved to Iceland about three years ago. More have followed suit since then or are in the process of moving. 

While some analysts are already sensing a possible new revenue source for the country that is so far mostly known abroad as a tourist haven and low-budget airline hub, others are more concerned by a phenomenon that has so far mostly alarmed analysts because of its possible financial unsustainability, alongside issues such as clean energy's dirty secret that complicate the picture. Some predictions have concluded that cryptocurrency computer operations may account for “all of the world’s energy by 2020” or may already account for the equivalent of Denmark's energy needs. Those predictions are probably too alarmist, though. 

Most analysts agree that the real energy-consumption figure is likely smaller, and several experts recently told the Washington Post that bitcoin — currently the world's biggest cryptocurrency — used no more than 0.14 percent of the world’s generated electricity, as of last December. Even though global consumption may not be as significant as some have claimed, it still presents a worrisome drain for a tiny country such as Iceland, where consumption suddenly began to spike with almost no warning — and continues to grow fast.

Some networks are considering or have already pushed through changes to their protocols, designed to reduce energy use. But implementing such changes for the leading currency, bitcoin, won't be as easy because it is inherently decentralized. The companies that provide the vast amounts of computing power needed for these transactions earn a small share, comparable to a processing fee or a reward.

They are the source of the Icelandic bitcoin miners’ income — a revenue source that many Icelanders are still not quite sure what to make of, especially if the lights start flickering.

Energy Vault Lands $110M From SoftBank’s Vision Fund for Gravity Storage

Energy Vault Gravity Storage uses crane-stacked concrete blocks to deliver long-duration, grid-scale renewable energy; a SoftBank Vision Fund-backed, pumped-hydro analog enabling baseload power and a lithium-ion alternative with proprietary control algorithms.

 

Key Points

Gravity-based cranes stack blocks to store and dispatch power for hours, enabling grid-scale, low-cost storage.

✅ 4 MW/35 MWh modules; ~9-hour duration

✅ Estimated $200-$250/kWh; lower LCOE than lithium-ion

✅ Backed by SoftBank Vision Fund; Cemex and Tata support

 

Energy Vault, the Swiss-U.S. startup that says it can store and discharge electrical energy through a super-sized concrete-and-steel version of a child’s erector set, has landed a $110 million investment from Japan’s SoftBank Vision Fund to take its technology to commercial scale.

Energy Vault, a spinout of Pasadena-based incubator Idealab and co-founded by Idealab CEO and billionaire investor Bill Gross, unstealthed in November with its novel approach to using gravity to store energy.

Simply put, Energy Vault plans to build storage plants — dubbed “Evies” — consisting of a 35-story crane with six arms, surrounded by a tower consisting of thousands of concrete bricks, each weighing about 35 tons.

This plant will “store” energy by using electricity to run the cranes that lift bricks from the ground and stack them atop of the tower, and “discharge” energy by reversing that process. It’s a mechanical twist on the world’s most common energy storage technology, pumped hydro, which “stores” energy by pumping water uphill, and lets it fall to spin turbines when electricity is needed, even as California funds 100-hour long-duration storage pilots to expand flexibility worldwide.

But behind this simplicity lies some heavy-duty software to orchestrate the cranes and blocks, with a "unique stack of proprietary algorithms" to balance energy supply and demand, volatility, grid stability, weather elements and other variables.

CEO and co-founder Robert Piconi said in a November interview with GTM that the standard array would deliver 4 megawatts/35 megawatt-hours of storage, which translates to nearly 9 hours of duration — the equivalent of building the tower to its height, and then reducing it to ground level. It can be built on-site in partnership with crane manufacturers and recycled concrete material, and can run fully automated for decades with little deterioration, he said.

And the cost, which Piconi pegged in the $200 to $250 per kilowatt-hour range, with room to decline further, is roughly 50 percent below the upfront price of the conventional storage market today, and 80 percent below it on levelized cost, he said, a trend utilities see benefits in as they plan resources.

The result, according to Wednesday’s statement, is a technology that could allow “renewables to deliver baseload power for less than the cost of fossil fuels 24 hours a day,” in applications such as community microgrids serving low-income housing.

Wednesday’s announcement builds on a recent investment from Mexico's Cemex Ventures, the corporate venture capital unit of building materials giant Cemex, along with a promise of deployment support from Cemex's strategic network, and also follows project financing for a California green hydrogen microgrid led by the company. Piconi said in November that the company had sufficient investment from two funding rounds to carry it through initial customer deployments, though he declined to disclose figures.

This is the first energy storage investment for Vision Fund, the $100 billion venture fund set up by SoftBank founder Masayoshi Son. While large by startup standards, it’s in keeping with the capital costs that Energy Vault will face in scaling up its technology to meet its commitments, amid mounting demand in regions like Ontario energy storage that face supply crunches. Those include a 35 megawatt-hour order with Tata Power Company, the energy-producing arm of the Indian industrial conglomerate, first unveiled in November, as well as plans to demonstrate its first storage tower in northern Italy in 2019.

For Vision Fund, it’s also an unusual choice for a storage investment, given that the vast majority of venture capital in the industry today is being directed toward lithium-ion batteries, and even Mercedes-Benz energy storage ventures targeting the U.S. market. Lithium-ion batteries are limited in terms of how many hours they can provide cost-effectively, with about 4 hours being seen as the limit today.

The search for long-duration energy storage has driven investment into flow battery technologies such as grid-scale vanadium systems deployed on utility networks, compressed-air energy storage and variations on gravity-based storage, including a previous startup backed by Gross and Idealab, Energy Cache, whose idea of using a ski lift carrying buckets of gravel up a hill to store energy petered out with a 50-kilowatt pilot project.
