U.S.-based Hydro Green Energy announced it started its first commercial hydrokinetic project.

HGE said it has successfully installed one of two underwater turbines in Hastings, Minn. The turbines are being installed downstream from a 4.4-megawatt U.S. Army Corps of Engineers hydropower plant.

The second turbine is expected to be installed in the spring.

"With the successful installation of our first turbine, Hydro Green Energy has taken another historic step and has strengthened its status as the industry leader," said Wayne Krouse, chairman and chief executive officer of HGE. "We, with the city of Hastings, are now in a position to soon send the first hydrokinetic electrons ever to the U.S. power grid."

Hydrokinetic power is generated from moving water in open rivers, tidal areas and oceans through suspended turbines.

The Hastings project was approved by the Federal Energy Regulatory Commission in December.

SaskPower to buy more electricity from Manitoba Hydro

SaskPower-Manitoba Hydro Power Sale outlines up to 215 MW of clean hydroelectric baseload for Saskatchewan, supporting renewable energy targets, lower greenhouse gas emissions, and interprovincial transmission line capacity starting 2022 under a 30-year agreement.

 

Key Points

A long-term deal supplying up to 215 MW of hydroelectric baseload from Manitoba to Saskatchewan to cut emissions.

✅ Up to 215 MW delivered starting 2022 via new intertie

✅ Supports 40% GHG reduction target by 2030

✅ 30-year term; complements wind and solar integration

 

Saskatchewan's Crown-owned electric utility has made an agreement to buy more hydroelectricty from Manitoba.

A term sheet providing for a new long--term power sale has been signed between Manitoba Hydro and SaskPower which will see up to 215 megawatts flow from Manitoba to Saskatchewan, as new turbine investments advance in Manitoba, beginning in 2022.

SaskPower has two existing power purchase agreements with Manitoba Hydro that were made in 2015 and 2016, but the newest one announced Monday is the largest, as financial pressures at Manitoba Hydro continue.

SaskPower President and CEO Mike Marsh says in a news release that the clean, hydroelectric power represents a significant step forward when it comes to reaching the utility's goal of reducing greenhouse gas emissions by 40 per cent by 2030, aligning with progress on renewable electricity by 2030 initiatives.

Marsh says it's also reliable baseload electricity, which SaskPower will need as it adds more intermittent generation options like wind and solar.

SaskPower says a final legal contract for the sale is expected to be concluded by mid-2019 and be in effect by 2022, and the purchase agreement would last up to 30 years.

"Manitoba Hydro has been a valued neighbour and business partner over the years and this is a demonstration of that relationship," Marsh said in the news release.

The financial terms of the agreement are not being released, though SaskPower's latest annual report offers context on its finances.

Both parties say the sale will partially rely on the capacity provided by a new transmission line planned for construction between Tantallon, Sask. and Birtle, Man. that was previously announced in 2015 and is expected to be in service by 2021.

"Revenues from this sale will assist in keeping electricity rates affordable for our Manitoba customers, while helping SaskPower expand and diversify its renewable energy supply," Manitoba Hydro president and CEO Kelvin Shepherd said in the utility's own news release.

In 2015, SaskPower signed a 25 megawatt agreement with Manitoba Hydro that lasts until 2022. A 20-year agreement for 100 megawatts was signed in 2016 and comes into effect in 2020, and SaskPower is also exploring a purchase from Flying Dust First Nation to further diversify supply.

The deals are part of a memorandum of understanding signed in 2013 involving up to 500 megawatts.

BC Ferries celebrates addition of hybrid ships

BC Ferries Island Class hybrid ferries deliver quiet, battery-electric travel with shore power readiness, lower emissions, and larger capacity on northern routes, protecting marine wildlife while replacing older vessels on Powell River and Texada services.

 

Key Points

Hybrid-electric ferries using batteries and diesel for quiet, low-emission service, ready for shore power upgrades.

✅ Operate 20% electric at launch; future full-electric via shore power

✅ 300 passengers, 47 vehicles; replacing older, smaller vessels

✅ Quieter transits help protect West Coast whales and marine habitat

 

In a champagne celebration, BC Ferries welcomed two new, hybrid-electric ships into its fleet Wednesday. The ships arrived in Victoria last month, and are expected to be in service on northern routes by the summer.

The Island Aurora and Island Discovery have the ability to run on either diesel or electricity.

"The pressure on whales on the West Coast is very intense right now," said BC Ferries CEO Mark Collins. "Quiet operation is very important. These ships will be gliding out of the harbor quietly and electrically with no engines running, that will be really great for marine space."

BC Ferries says the ships will be running on electricity 20 per cent of the time when they enter service, but the company hopes they can run on electricity full-time in the future. That would require the installation of shoreline power, which the company hopes to have in place in the next five to 10 years. Each ship costs around $40-million, a price tag that the federal government partially subsidized through CIB support as part of the electrification push.

When the two ships begin running on the Powell River to Texada, and Port McNeill, Alert Bay, and Sointula routes, two older vessels will be retired.

On Kootenay Lake, an electric-ready ferry is slated to begin operations in 2023, reflecting the province's wider shift.

"They are replacing a 47-car ferry, but on some routes they will be replacing a 25-car ferry, so those routes will see a considerable increase in service," said Collins.

Although the ships will not be servicing Colwood, the municipality's mayor is hoping that one day, they will.

"We can look at an electric ferry when we look at a West Shore ferry that would move Colwood residents to Victoria," said Mayor Rob Martin, noting that across the province electric school buses are hitting the road as well. "Here is a great example of what BC Ferries can do for us."

BC Ferries says it will be adding four more hybrid ships to its fleet by 2022, and is working on adding hybrid ships that could run from Victoria to Tsawwassen, similar to Washington State Ferries' hybrid upgrade underway in the region. 

B.C’s first hybrid-electric ferries arrived in Victoria on Saturday morning ushering in a new era of travel for BC Ferries passengers, as electric seaplane flights are also on the horizon for the region.

“It’s a really exciting day for us,” said Tessa Humphries, spokesperson for BC Ferries.

It took the ferries 60 days to arrive at the Breakwater District at Ogden Point. They came all the way from Constanta, Romania.

“These are battery-equipped ships that are designed for fully electric operation; they are outfitted with hybrid technology that bridges the gap until the EV charging infrastructure and funding is available in British Columbia,” said Humphries.

The two new "Island Class" vessels arrived at about 9 a.m. to a handful of people eagerly wanting to witness history.

Sometime in the next few days, the transport ship that brought the new ferries to B.C. will go out into the harbor and partially submerge to allow them to be offloaded, Humphries said.

The transfer process could happen in four to five days from now. After the final preparations are finished at the Breakwater District, the ships will be re-commissioned in Point Hope Maritime and then BC Ferries will officially take ownership.

“We know a lot of people are interested in this so we will put out advisory once we have more information as to a viewing area to see the whole process,” said Humphries.

Both Island Class ferries can carry 300 passengers and 47 vehicles. They won’t be sailing until later this year, but Humphries tells CTV News they will be named by the end of February.

Quebec premier inaugurates La Romaine hydroelectric complex

La Romaine Hydroelectric Complex anchors Quebec's hydropower expansion, showcasing Hydro-Québec ingenuity, clean energy, electrification, and grid capacity gains along the North Shore's Romaine River to power industry and nearly 470,000 homes.

 

Key Points

A four-station, $7.4B hydro project on Quebec's Romaine River producing 8 TWh a year for electrification and industry.

✅ Generates 8 TWh yearly, powering about 470,000 homes

✅ Largest Quebec hydro build since James Bay project

✅ Key to clean energy, grid capacity, and electrification

 

Quebec Premier François Legault has inaugurated the la Romaine hydroelectric complex on the province's North Shore.

The newly inaugurated Romaine hydroelectric complex could serve as a model for future projects, such as the Carillon Generating Station investment now planned in the province, Legault said.

"It brings me a lot of pride. It is truly the symbol of Quebec ingenuity," he said as he opened the vast power plant.

Legault was accompanied at today's event by Jean Charest, who was Quebec premier when construction began in 2009, as well as Hydro-Québec president and CEO Michael Sabia. 

La Romaine is comprised of four power stations and is the largest hydro project constructed in the province since the Robert Bourassa generation facility, which was commissioned in 1979. It is the biggest hydro installation since the James Bay project, bolstering Hydro-Québec's hydropower capacity across the grid today.

The construction work for Romaine-4 was supposed to finish in 2020, but it was delayed the COVID-19 pandemic, the death of four workers due to security flaws and soil decomposition problems. 

The $7.4-billion la Romaine complex can produce eight terawatt hours of electricity per year, enough to power nearly 470,000 homes.

It generates its power from the Romaine River, located north of Havre-St-Pierre, Que., near the Labrador border, where long-standing Newfoundland and Labrador tensions over Quebec's projects sometimes resurface today.

Legault said that Quebec still doesn't have enough electricity to meet demand from industry, including recent allocations of electricity for industrial projects across the province, and Quebecers need to consider more ways to boost the province's ability to power future projects. The premier has said previously that demand is expected to surge by an additional 100 terawatt-hours by 2050 — half the current annual output of the provincially owned utility.

Legault's environmental plan of reducing greenhouse gases and achieving carbon neutrality by 2050 hinges on increased electrification and a strategy to wean off fossil fuels provincewide, so the electricity needs for transport and industry will be massive.

An updated strategic plan from Hydro-Quebec will be presented in November outlining those needs, president and CEO Michael Sabia told reporters on Thursday, after recent deals with NB Power underscored interprovincial demand.

Legault said the report will trigger a broader debate on energy transition and how the province can be a leader in the green economy. He said he wasn't ruling out any potential power sources — except for a return to nuclear power at this stage.

UK must start construction of large-scale storage or fail to meet net zero targets.

UK Hydrogen Storage Caverns enable long-duration, low-carbon electricity balancing, storing surplus wind and solar power as green hydrogen in salt formations to enhance grid reliability, energy security, and net zero resilience by 2035 and 2050.

 

Key Points

They are salt caverns storing green hydrogen to balance wind and solar, stabilizing a low-carbon UK grid.

✅ Stores surplus wind and solar as green hydrogen in salt caverns

✅ Enables long-duration, low-carbon grid balancing and security

✅ Complements wind and solar; reduces dependence on flexible CCS

 

The U.K. government must kick-start the construction of large-scale hydrogen storage facilities if it is to meet its pledge that all electricity will come from low-carbon electricity sources by 2035 and reach legally binding net zero targets by 2050, according to a report by the Royal Society.

The report, "Large-scale electricity storage," published Sep. 8, examines a wide variety of ways to store surplus wind and solar generated electricity—including green hydrogen, advanced compressed air energy storage (ACAES), ammonia, and heat—which will be needed when Great Britain's electricity generation is dominated by volatile wind and solar power.

It concludes that large scale electricity storage is essential to mitigate variations in wind and sunshine, particularly long-term variations in the wind, and to keep the nation's lights on. Storing most of the surplus as hydrogen, in salt caverns, would be the cheapest way of doing this.

The report, based on 37 years of weather data, finds that in 2050 up to 100 Terawatt-hours (TWh) of storage will be needed, which would have to be capable of meeting around a quarter of the U.K.'s current annual electricity demand. This would be equivalent to more than 5,000 Dinorwig pumped hydroelectric dams. Storage on this scale, which would require up to 90 clusters of 10 caverns, is not possible with batteries or pumped hydro.

Storage requirements on this scale are not currently foreseen by the government, and the U.K.'s energy transition faces supply delays. Work on constructing these caverns should begin immediately if the government is to have any chance of meeting its net zero targets, the report states.

Sir Chris Llewellyn Smith FRS, lead author of the report, said, "The need for long-term storage has been seriously underestimated. Demand for electricity is expected to double by 2050 with the electrification of heat, transport, and industrial processing, as well as increases in the use of air conditioning, economic growth, and changes in population.

"It will mainly be met by wind and solar generation. They are the cheapest forms of low-carbon electricity generation, but are volatile—wind varies on a decadal timescale, so will have to be complemented by large scale supply from energy storage or other sources."

The only other large-scale low-carbon sources are nuclear power, gas with carbon capture and storage (CCS), and bioenergy without or with CCS (BECCS). While nuclear and gas with CCS are expected to play a role, they are expensive, especially if operated flexibly.

Sir Peter Bruce, vice president of the Royal Society, said, "Ensuring our future electricity supply remains reliable and resilient will be crucial for our future prosperity and well-being. An electricity system with significant wind and solar generation is likely to offer the lowest cost electricity but it is essential to have large-scale energy stores that can be accessed quickly to ensure Great Britain's energy security and sovereignty."

Combining hydrogen with ACAES, or other forms of storage that are more efficient than hydrogen, could lower the average cost of electricity overall, and would lower the required level of wind power and solar supply.

There are currently three hydrogen storage caverns in the U.K., which have been in use since 1972, and the British Geological Survey has identified the geology for ample storage capacity in Cheshire, Wessex and East Yorkshire. Appropriate, novel business models and market structures will be needed to encourage construction of the large number of additional caverns that will be needed, the report says.

Sir Chris observes that, although nuclear, hydro and other sources are likely to play a role, Britain could in principle be powered solely by wind power and solar, supported by hydrogen, and some small-scale storage provided, for example, by batteries, that can respond rapidly and to stabilize the grid. While the cost of electricity would be higher than in the last decade, we anticipate it would be much lower than in 2022, he adds.

California proposes income-based fixed electricity charges

Income Graduated Fixed Charge aligns CPUC billing with utility fixed costs, lowers usage rates, supports electrification, and shifts California investor-owned utilities' electric bills by income, with CARE and Climate Credit offsets for low-income households.

 

Key Points

A CPUC proposal: an income-based monthly fixed fee with lower usage rates to align costs and aid low-income customers.

✅ Income-tiered fixed fees: $0-$42; CARE: $14-$22, by utility territory

✅ Usage rates drop 16%-22% to support electrification and cost-reflective billing

✅ Lowest-income save ~$10-$20; some higher earners pay ~$10+ more monthly

 

The Public Advocates Office (PAO) for the California Public Utilities Commission (CPUC) has proposed adding a monthly income-based fixed charge on electric utility bills based on income level.  

The rate change is designed to lower bills for the lowest-income residents while aligning billing more directly with utility costs. 

PAO’s recommendation for the Income Graduated Fixed Charge places fees between $22 and $42 per month in the three major investor-owned utilities’ territories, including an SDG&E minimum charge debate under way, for customers not enrolled in the California Alternative Rates for Energy (CARE) program. As seen below, CARE customers would be charged between $14 per month and $22 a month, depending on income level and territory.

For households earning $50,000 or less per year, the fixed charge would be $0, but only if the California Climate Credit is applied to offset the fixed cost.

Meanwhile, usage-based electricity rates are lowered in the PAO proposal, part of major changes to electric bills statewide. Average rates would be reduced between 16% to 22% for the three major investor-owned utilities.

The lowest-income bracket of Californians is expected to save roughly $10 to $20 a month under the proposal, while middle-income customers may see costs rise by about $20 a month, even as lawmakers seek to overturn income-based charges in Sacramento.

“We anticipate the vast majority of low-income customers ($50,000 or less per year) will have their monthly bills decrease by $10 or more, and a small proportion of the highest income earners ($100,000+ per year) will see their monthly bills rise by $10 or more,” said the PAO.

The charges are an effort to help suppress ever-increasing electricity generation and transmission rates, which are among the highest in the country, with soaring electricity prices reported across California. Rates are expected to rise sharply as wildfire mitigation efforts are implemented by the utilities found at fault for their origin.

“We are very concerned. However, we do not see the increases stopping at this point,” Linda Serizawa, deputy director for energy, PAO, told pv magazine. “We think the pace and scale of the [rate] increases is growing faster than we would have anticipated for several years now.”

Consumer advocates and regulators face calls for action on surging electricity bills across the state.

The proposed changes are also meant to more directly couple billing with the fixed charges that utilities incur, as California considers revamping electricity rates to clean the grid. For example, activities like power line maintenance, energy efficiency programs, and wildfire prevention are not expected to vary with usage, so these activities would be funded through a fixed charge.

Michael Campbell of the PAO’s customer programs team, and leader of the proposed program, likened paying for grid enhancements and other social programs with utility rate increases to “paying for food stamps by taxing food.” Instead, a fixed charge would cover these costs.

PAO said the move to lower rates for usage should help encourage electrification as California moves to replace heating and cooling, appliances, and gas combustion cars with electrified counterparts. In addition, lower rates mean the cost burden of running these devices is improved.

Utilities commission changes community choice exit fees; what happens now in San Diego?

CPUC Exit Fee Increase for CCAs adjusts the PCIA, affecting utilities, San Diego ratepayers, renewable energy procurement, customer equity, and cost allocation, while providing regulatory certainty for Community Choice Aggregation programs and clean energy goals.

 

Key Points

A CPUC-approved change raising PCIA exit fees paid by CCAs to utilities, balancing cost shifts and customer equity.

✅ PCIA rises from about 2.5c to roughly 4.25c per kWh in San Diego

✅ Aims to reduce cost shifts and protect non-CCA customers

✅ Offers regulatory certainty for CCA launches and clean energy goals

 

The California Public Utilities Commission approved an increase on the exit fees charged to customers who take part in Community Choice Aggregation -- government-run alternatives to traditional utilities like San Diego Gas & Electric.

After reviewing two competing exit fee proposals, all five commissioners voted Thursday in favor of an adjustment that many CCA advocates predicted could hamper the growth of the community choice movement.

But minutes after the vote was announced, one of the leading voices in favor of the city San Diego establishing its own CCA said the decision was good news because it provides some regulatory certainty.

"For us in San Diego, it's a green light to move forward with community choice," said Nicole Capretz, executive director of the Climate Action Campaign. "For us, it's let's go, let's launch and let's give families a choice. We no longer have to wait."

Under the CCA model, utilities still maintain transmission and distribution lines (poles and wires, etc.) and handle customer billing. But officials in a given local government entity make the final decisions about what kind of power sources are purchased.

Once a CCA is formed, its customers must pay an exit fee -- called a Power Charge Indifference Adjustment -- to the legacy utility serving that particular region. The fee is included in customers' monthly bills.

The fee is required to offset the costs of the investments utilities made over the years for things like natural gas power plants, renewable energy facilities and other infrastructure.

Utilities argue if the exit fee is set too low, it does not fairly compensate them for their investments; if it's too high, CCAs complain it reduces the financial incentive for their potential customers.

The Public Utilities Commission chose to adopt a proposal that some said was more favorable to utilities, leading to complaints from CCA boosters.

"We see this will really throw sand in the gears in our ability to do things that can move us toward (climate change) goals," Jim Parks, staff member of Valley Clean Energy, a CCA based in Davis, said before the vote.

Commissioner Carla Peterman, who authored the proposal that passed, said she supports CCAs but stressed the commission has a "legal obligation" to make sure increased costs are not shouldered by "customers who do not, or cannot, join a CCA. Today's proposal ensures a more level playing field between customers."

As for what the vote means for the exit fee in San Diego, Peterman's office earlier in the week estimated the charge would rise from 2.5 cents a kilowatt-hour to about 4.25 cents.

The Clear the Air Coaltion, a San Diego County group critical of CCAs, said the newly established exit fee -- which goes into effect starting next year -- is "a step in the direction."

But the group, which includes the San Diego Regional Chamber of Commerce, the San Diego County Taxpayers Association and lobbyists for Sempra Energy (the parent company of SDG&E), repeated concerns it has brought up before.

"If the city of San Diego decides to get into the energy business this decision means ratepayers in National City, Chula Vista, Carlsbad, Imperial Beach, La Mesa, El Cajon and all other neighboring communities would see higher energy bills, and San Diego taxpayers would be faced with mounting debt," coalition spokesman Tony Manolatos said in an email.

CCA supporters say community choice is critical in ensuring San Diego meets the pledge made by Mayor Kevin Faulconer to adopt the city's Climate Action Plan, mandating 100 percent of the city's electricity needs must come from renewable sources by 2035.

Now attention turns to Faulconer, who promised to make a decision on bringing a CCA proposal to the San Diego City Council only after the utilities commission made its decision.

A Faulconer spokesman said Thursday afternoon that the vote "provides the clarity we've been waiting for to move forward" but did not offer a specific time table.

"We're on schedule to reach Mayor Faulconer's goal of choosing a pathway that achieves our renewable energy goals while also protecting ratepayers, and the mayor looks forward to making his recommendation in the next few weeks," said Craig Gustafson, a Faulconer spokesman, in an email.

A feasibility study released last year predicted a CCA in San Diego has the potential to deliver cheaper rates over time than SDG&E's current service, while providing as much as 50 percent renewable energy by 2023 and 80 percent by 2027.

"The city has already figured out we are still capable of launching a program, having competitive, affordable rates and finally offering families a choice as to who their energy provider is," said Capretz, who helped draft an initial blueprint of the climate plan as a city staffer.

SDG&E has come to the city with a counterproposal that offers 100 percent renewables by 2035.

Thus far, the utility has produced a rough outline for a "tariff" program that would charge ratepayers the cost of delivering more clean sources of energy over time.

Some council members have expressed frustration more specifics have not been sketched out.

SDG&E officials said they will take the new exit fee into account as they go forward with their counterproposal to the city council.

Speaking in general about the utility commission's decision, SDG&E spokeswoman Helen Gao called it "a victory for our customers, as it minimizes the cost shifts that they have been burdened with under the existing fee formula.

"As commissioners noted in rendering their decision, reforming the (exit fee) addresses a customer-to-customer equity issue and has nothing to do with increasing profits for investor-owned utilities," Gao said in an email.
