If youÂ’re a recent convert to smartphones, youÂ’re probably still discovering all the amazing things that your new BlackBerry, Android phone or iPhone can do. But one thing you most likely found out right away: the more you do, the shorter your phoneÂ’s battery lasts.

While a standard cellphone’s charge can easily go three days or more, many smartphone owners are dismayed to learn that their new mobile toy requires charging every 24 hours, or even more often. It was great that I could use one device — my iPhone — to check my calendar and respond to multiple incoming calls during the recent Consumer Electronics Show, but I paid the price when its battery died at 2 p.m.

The answer was not to desperately search for an electrical outlet to recharge the phone (though IÂ’ve done that) or to consider giving up the phone (done that, too), but rather to figure out a strategy to reduce energy consumption while still having it available for essential tasks. Whether youÂ’re using a laptop or a smartphone, the devices can be tweaked to get the most out of its lithium-ion batteries.

All things being equal, the CDMA mobile standard used by Verizon uses more power than a GSM network, principally used by AT&T and T-Mobile. If battery life is critical, you might want to consider GSM as long as its coverage meets your needs.

The brighter your screen, the more juice youÂ’re using. If youÂ’re in a dimly lit room, turn down your LCD screenÂ’s brightness. If your device has an auto-dimming feature that detects the light in a room, use it. Similarly, if you use your smartphone or laptop to play music, lower the volume.

If you have a BlackBerry, the companyÂ’s holster will automatically turn off the screen when you insert the phone.

It is great that you can use Bluetooth technology to connect your smartphone to a headset, or use Wi-Fi to speed up the downloading of e-mail messages. But when youÂ’re not using that headset or not near a Wi-Fi hot spot, turn off those features on the phone or laptop.

The reason is that portable devices will continue to look for Wi-Fi or a Bluetooth headset, using power.

Similarly, put your phone to sleep when it is in standby. On an iPhone, you do so through the “Settings” icon. On a BlackBerry, use the “Manage Connections” icon.

Your smartphone is also continually looking for a cellphone signal. If youÂ’re in a weak signal area, your phone must work even harder to find one, decreasing battery life. If you know that there is no coverage in your area, turn off your portable deviceÂ’s mobile capabilities.

If your GSM 3G network is not available or the signal is weak, the battery will drain faster looking for one. Consider turning off the phoneÂ’s 3G network or using the slower EDGE network instead. It will make Web access slower but wonÂ’t affect phone call quality.

Mobile smartphones can check for e-mail messages and instant messages automatically. Or they can be set to “push” notifications as soon as they arrive in your server’s mailbox.

Both strategies can be power hogs. To increase your battery life, turn off push and increase the interval between when the phone checks for new messages. Or better, set up your phone to check for messages manually.

The simplest way to cut power to a minimum is to put your smartphone into “airplane mode.” You turn your BlackBerry or iPhone into a music player and personal organizer, and you won’t be able to receive e-mail messages or make or receive phone calls, but you will stretch your battery.

“In airplane mode and running just the alarm clock, your iPhone battery will last up to a week,” said Kyle Wiens, co-founder of ifixit.com, an online iPhone and Mac laptop repair company.

The hotter your laptop feels, the more battery power it is using. And one of the biggest users of power is Flash animation, the technology behind many online videos and animated ads. To improve battery life, disable Flash when not using wall power. BashFlash and ClicktoFlash for Macs and Flashblock for PC are programs that will automatically restrict Flash.

There are a number of applications that can help monitor battery life and shut off various functions that cut down on a mobile deviceÂ’s effective power.

Battery Go and myBatteryLife tell iPhone owners how much charge they have left and how that power translates into minutes of talk time, music, video and Web surfing.

NB BattStat alerts BlackBerry owners to the amount of battery charge remaining, as well as the batteryÂ’s temperature. (Hot batteries lose power more quickly.) The device can be set to vibrate or sound when a predetermined low battery level is reached.

Radio Saver will monitor your BlackBerryÂ’s mobile coverage and shut off the deviceÂ’s mobile circuitry when you are out of range of a cellular signal.

Best BatterySaver allows owners of mobile phones using the Symbian operating system (including models from Nokia and Sony Ericsson) to create battery-saving profiles. For example, certain features can be automatically turned on when the phone is connected to a wall plug, or Bluetooth can be automatically disconnected when the battery charge drops below a certain level.

For laptops, programs like Battery Health Monitor (Mac) and Laptop Battery Power Monitor (PC) keep track of battery charge and estimate how many more times youÂ’ll be able to recharge your battery.

The older generation of nickel cadmium batteries suffered from memory issues; if you didnÂ’t fully charge and discharge one, it would hold a progressively smaller amount of juice.

TodayÂ’s lithium-ion batteries donÂ’t suffer from memory loss, so it is safe to top off a battery.

Lithium-ion batteries cannot be overcharged; a deviceÂ’s circuitry cuts off the power when they are full. However, manufacturers still recommend that a laptop not be continually connected to power once the battery is at its capacity. If a laptop wonÂ’t be used for several months, it should be stored with the battery in a 50 percent charge state.

All batteries can be fully charged and discharged for a fixed number of cycles; lithium ion batteries typically last between 300 and 500 cycles. Information on the number of cycles can be obtained at manufacturersÂ’ Web sites, or at batteryuniversity.com.

No matter how well you husband your batteryÂ’s resources, there comes a time when youÂ’ll need to send your battery to its final resting place.

Like most things nearing the end of their life, your battery will stay awake less and sleep more. “If your battery lasts only an hour after you’ve charged it,” said Anthony Magnabosco, owner of Milliamp.com, a battery replacement company, “you know its time is up.”

Investor: Hydro One has too many unknowns to be a good investment

Hydro One investment risk reflects Ontario government influence, board shakeup, Avista acquisition uncertainty, regulatory hearings, dividend growth prospects, and utility M&A moves in Peterborough, with stock volatility since the 2015 IPO.

 

Key Points

Hydro One investment risk stems from political control, governance turnover, regulatory outcomes, and uncertain M&A.

✅ Ontario retains near-50% stake, affecting autonomy and policy risk

✅ Board overhaul and CEO exit create governance uncertainty

✅ Avista deal, OEB hearings, local utility M&A drive outcomes

 

Hydro One may be only half-owned by the province on Ontario but that’s enough to cause uncertainty about the company’s future, thus making for an investment risk, says Douglas Kee of Leon Frazer & Associates.

Since its IPO in November of 2015, Hydro One has seen its share of ups and downs, including a Q2 profit decline earlier this year, mostly downs at this point. Currently trading at $19.87, the stock has lost 11 per cent of its value in 2018 and 12 per cent over the last 12 months, despite a one-time gain boosting Q2 profit that followed a court ruling.

This year has been a turbulent one, to say the least, as newly elected Ontario premier Doug Ford made good this summer on his campaign promise re Hydro One by forcing the resignation of the company’s 14-person board of directors along with the retirement of its chief executive, an event that saw Hydro One shares fall amid the turmoil. An interim CEO has been found and a new 10-person board and chairman put in place, but Kee says it’s unclear what impact the shakeup will ultimately have, other than delaying a promising-looking deal to purchase US utility Avista Corp, with the companies moving to ask the U.S. regulator to reconsider the order.

 

Douglas Kee’s take on Hydro One stock

“We looked at Hydro One a couple of times two years ago and just decided that with the Ontario government’s still owning a big chunk of the company … there are other public companies where you get the same kind of yield, the same kind of dividend growth, so we just avoided it,” says Kee, managing director and chief investment officer with Leon Frazer & Associates, to BNN Bloomberg.

“The old board versus the new board, I’m not sure that there’s much of an improvement. It was politics more than anything,” he says. “The unfortunate part is that the acquisition they were making in the United States is kind of on hold for now. The regulatory procedures have gone ahead but they are worried, and I guess the new board has to make a decision whether to go ahead with it or not.”

“Their transmissions side is coming up for regulatory hearings next year, which could be difficult in Ontario,” says Kee. “The offset to that is that there are a lot of municipal distributions systems in Ontario that may be sold — they bought one in Peterborough recently, which was a good deal for them. There may be more of that coming too.”

Last month, Hydro One reached an agreement with the City of Peterborough to buy its Peterborough Distribution utility which serves about 37,000 customers for $105 million. Another deal to purchase Orillia Power Distribution Corp for $41 million has been cancelled after an appeal to the Ontario Energy Board was denied in late August. Hydro One’s sought-after Avista Corp acquisition is reported to be worth $7 billion.

N.L. premier says Muskrat Falls costs are too great for optimism about benefits

Muskrat Falls financial impact highlights a hydro megaproject's cost overruns, rate mitigation challenges, and inquiry findings in Newfoundland and Labrador, with power exports, Churchill River generation, and subsea cables shaping long-term viability.

 

Key Points

It refers to the project's burden on provincial finances, driven by cost overruns, rate hikes, and debt risks.

✅ Costs rose to $12.7B from $6.2B; inquiry cites suppressed risks.

✅ Rate mitigation needed to offset power bill shocks.

✅ Exports via subsea cables may improve long-term viability.

 

Newfoundland and Labrador's premier says the Muskrat Falls hydro megaproject is currently too much of a massive financial burden for him to be optimistic about its long-term potential.

"I am probably one of the most optimistic people in this room," Liberal Premier Dwight Ball told the inquiry into the project's runaway cost and scheduling issues, echoing challenges at Manitoba Hydro that have raised similar concerns.

"I believe the future is optimistic for Newfoundland Labrador, of course I do. But I'm not going to sit here today and say we have an optimistic future because of the Muskrat Falls project."

Ball, who was re-elected on May 16, has been critical of the project since he was opposition leader around the time it was sanctioned by the former Tory government.

He said Friday that despite his criticism of the Labrador dam, which has seen costs essentially double to more than $12.7 billion, he didn't set out to celebrate a failed project.

He said he still wants to see Muskrat Falls succeed someday through power sales outside the province, but there are immediate challenges -- including mitigating power-rate hikes once the dam starts providing full power and addressing winter reliability risks for households.

"We were told the project would be $6.2 billion, we're at $12.7 (billion). We were never told this project would be nearly 30 per cent of the net debt of this province just six, seven years later," the premier said.

"I wanted this to be successful, and in the long term I still want it to be successful. But we have to deal with the next 10 years."

The nearly complete dam will harness Labrador's lower Churchill River to provide electricity to the province as well as Nova Scotia and potentially beyond through subsea cables, while the legacy of Churchill Falls continues to shape regional power arrangements.

Ball's testimony wraps up a crucial phase of hearings in the extensive public inquiry.

The inquiry has heard from dozens of witnesses, with current and former politicians, bureaucrats, executives and consultants, amid debates over Quebec's electricity ambitions in the region, shedding long-demanded light on what went on behind closed doors that made the project go sideways.

Some witnesses have suggested that estimates were intentionally suppressed, and many high-ranking officials, including former premiers, have denied seeing key information about risk.

On Thursday, Ball testified to his shock when he began to understand the true financial state of the project after he was elected premier in 2015.

On Friday, Ball said he has more faith in future of the offshore oil and gas industry, and emerging options like small nuclear reactors, for example, than a mismanaged project that has put immense pressure on residents already struggling to make ends meet.

After his testimony, Ball said he takes some responsibility for a missed opportunity to mitigate methylmercury risks downstream from the dam through capping the reservoir, in parallel with debates over biomass power in electricity generation, something he had committed to doing before it is fully flooded this summer.

Still to come is a third phase of hearings on future best practices for issues like managing large-scale projects and independent electricity planning, two public feedback sessions and closing submissions from lawyers.

The final report from the inquiry is due before Dec. 31.

Canadian Gov't and PEI invest in new transmission line to support wind energy production

Skinners Pond Transmission Line expands PEI's renewable energy grid, enabling wind power integration, grid reliability, and capacity for the planned 40 MW windfarm, funded through the Green Infrastructure Stream to support sustainable economic growth.

 

Key Points

A 106-km grid project enabling PEI wind power, increasing capacity and reliability, linking Skinners Pond to Sherbrooke.

✅ 106-km line connects Skinners Pond to Sherbrooke substation

✅ Integrates 40 MW windfarm capacity by 2025

✅ Funded by Canada and PEI via Green Infrastructure Stream

 

The health and well-being of Canadians are the top priorities of the Governments of Canada and Prince Edward Island. But the COVID-19 pandemic has affected more than Canadians' personal health. It is having a profound effect on the economy.

That is why governments have been taking decisive action together to support families, businesses and communities, and continue to look ahead to planning for our electricity future and see what more can be done.

Today, Bobby Morrissey, Member of Parliament for Egmont, on behalf of the Honourable Catherine McKenna, Minister of Infrastructure and Communities, the Honourable Dennis King, Premier of Prince Edward Island, the Honourable Dennis King, Premier of Prince Edward Island, and the Honourable Steven Myers, Prince Edward Island Minister of Transportation, Infrastructure and Energy, announced funding to build a new transmission line from Sherbrooke to Skinners Pond, as part of broader Canadian collaboration on clean energy, with several premiers nuclear reactor technology to support future needs as well.

The new 106-kilometre transmission line and its related equipment will support future wind energy generation projects in western Prince Edward Island, complementing the Eastern Kings wind farm expansion already advancing. Once completed, the transmission line will increase the province's capacity to manage the anticipated 40 megawatts from the future Skinner's Pond Windfarm planned for 2025 and provide connectivity to the Sherbrooke substation to the northeast of Summerside.

The Government of Canada is investing $21.25 million and the Government of Prince Edward Island is providing $22.75 million in this project, reflecting broader investments in new turbines across Canada, through the Green Infrastructure Stream (GIS) of the Investing in Canada infrastructure program.

This projects is one in a series of important project announcements that will be made across the province over the coming weeks. The Governments of Canada and Prince Edward Island are working cooperatively to support jobs, improve communities and build confidence, while safely and sustainably restoring economic growth, as Nova Scotia increases wind and solar projects across the region.

"Investing in renewable energy infrastructure is essential to building healthy, inclusive, and resilient communities. The new Skinners Pond transmission line will support Prince Edward Island's production of green energy, focusing on wind resources rather than expanded biomass use in the mix. Projects like this also support economic growth and help us build a greener future for the next generation of Islanders."

Bobby Morrissey, Member of Parliament for Egmont, on behalf of the Honourable Catherine McKenna, Minister of Infrastructure and Communities

"We live on an Island that has tremendous potential in further developing renewable energy. We have an opportunity to become more sustainable and be innovative in our approach, and learn from regions where provinces like Manitoba have clean energy to help neighbouring provinces through interties. The strategic investment we are making today in the Skinner's Pond transmission line will allow Prince Edward Island to further harness the natural power of wind to create clean, locally produced and locally used energy that will benefit of all Islanders."

Canadian Solar and Tesla contribute to resilient electricity system for Puerto Rico school

SunCrate Solar Microgrid delivers resilient, plug-and-play renewable power to Puerto Rico schools, combining Canadian Solar PV, Tesla Powerwall battery storage, and Black & Veatch engineering to ensure off-grid continuity during outages and disasters.

 

Key Points

A compact PV-and-battery system for resilient, diesel-free power and microgrid backup at schools and clinics.

✅ Plug-and-play, modular PV, inverter, and battery architecture

✅ Tesla Powerwall storage; Canadian Solar 325 W panels

✅ Scales via daisy-chain for higher loads and microgrids

 

Eleven months since their three-building school was first plunged into darkness by Hurricane Maria, 140 students in Puerto Rico’s picturesque Yabucoa district have reliable power. Resilient electricity service was provided Saturday to the SU Manuel Ortiz school through an innovative scalable, plug-and-play solar system pioneered by SunCrate Energy with Black & Veatch support. Known as a “SunCrate,” the unit is an effective mitigation measure to back up the traditional power supply from the grid. The SunCrate can also provide sustainable power in the face of ongoing system outages and future natural disasters without requiring diesel fuel.

The humanitarian effort to return sustainable electricity to the K-8 school, found along the island’s hard-hit southeastern coast, drew donated equipment and expertise from a collection of North American companies. Additional support for the Yabucoa project came from Tesla, Canadian Solar and Lloyd Electric, reflecting broader efforts to build a solar-powered grid in Puerto Rico after Hurricane Maria.

“We are grateful for this initiative, which will equip this school with the technology needed to become a resilient campus and not dependent on the status of the power grid. This means that if we are hit with future harmful weather events, the school will be able to open more quickly and continue providing services to students,” Puerto Rico Secretary of Education Julia Keleher said.

The SunCrate harnesses a scalable rapid-response design developed by Black & Veatch and manufactured by SunCrate Energy. Electricity will be generated by an array of 325-W CS6U-Poly modules from Canadian Solar. California-based Tesla contributed advanced battery energy storage through various Powerwall units capable of storing excess solar power and delivering it outside peak generation periods, with related experience from a virtual power plant in Texas informing deployment.  Lloyd Electric Co. of Wichita Falls, Texas, partnered to support delivery and installation of the SunCrate.

“As families in the region begin to prepare for the school year, this community is still impacted by the longest U.S. power outage in history,” said Dolf Ivener, a Midwestern entrepreneur who owns King of Trails Construction and SunCrate Energy, which is donating the SunCrate. “SunCrate, with its rapid deployment and use of renewable energy, should give this school peace of mind and hopefully returns a touch of long-overdue normalcy to students and their parents. When it comes to consistent power, SunCrate is on duty.”

The SunCrate is a portable renewable energy system conceived by Ivener and designed and tested by Black & Veatch. Its modular design uses solar PV panels, inverters and batteries to store and provide electric power in support of critical services such as police, fire, schools, clinics and other community level facilities.

A SunCrate can generate 23 to 156 kWh per day, and store 10 kWh to 135 kWh depending on configuration. A SunCrate’s power generation and storage capacity can be easily scaled through daisy-chained configurations to accommodate larger buildings and loads. Leveraging resources from Tesla, Canadian Solar, Lloyd Electric and Lord Electric, the unit in Yabucoa will provide an estimated 52 kWh of storable power without requiring use of costlier diesel-powered generators and cutting greenhouse gas emissions. Its capabilities allow the school to strengthen its function as a designated Community Emergency Response Center in the event of future natural disasters.

“Canadian Solar has a long history of using solar power to support humanitarian efforts aiding victims of social injustice and natural disasters, including previous donations to Puerto Rico after Hurricane Maria,” said Dr. Shawn Qu, Chairman and Chief Executive Officer of Canadian Solar. “We are pleased to make the difference for these schoolchildren in Yabucoa who have been without reliable power for too long.”

The SunCrate will also substantially lower the school’s ongoing electricity costs by providing a reliable source of renewable energy on site, as falling costs of solar batteries improve project economics overall.

“Through our experience providing engineering services in Puerto Rico for nearly 50 years, including dozens of specialized projects for local government and industrial clients, we see great potential for SunCrate as a source of resilient power for the Commonwealth’s remote schools and communities at large, underscoring the importance of electricity resilience across critical infrastructure,” said Charles Moseley, a Program Director in Black & Veatch’s water business. “We hope that the deployment of the SunCrate in Yabucoa sets a precedent for facility and municipal level migro-grid efforts on the island and beyond.”

SunCrate also has broad potential applications in conflict/post-conflict environments and in rural electrification efforts in the developing world, serving as a resilient source of electricity within hours of its arrival on site and could enable peer-to-peer energy within communities. Of particular benefit, the system’s flexibility cuts fuel costs to a fraction of a generator’s typical consumption when they are used around the clock with maintenance requirements.

Solar Plus Battery Storage Cheaper Than Conventional Power in Germany

Germany Solar-Plus-Storage Cost Parity signals grid parity as solar power with battery storage undercuts conventional electricity. Falling LCOE, policy incentives, and economies of scale accelerate the energy transition and decarbonization across Germany's power market.

 

Key Points

The point at which solar power with battery storage is cheaper than conventional grid electricity across Germany.

✅ Lower LCOE from tech advances and economies of scale

✅ EEG incentives and streamlined installs cut total costs

✅ Enhances energy security, reduces fossil fuel dependence

 

Germany, a global leader in renewable energy adoption, with clean energy supplying about half of its electricity in recent years, has reached a significant milestone: the cost of solar power combined with battery storage has now fallen below that of conventional electricity sources. This development marks a transformative shift in the energy landscape, showcasing the increasing affordability and competitiveness of renewable energy technologies and reinforcing Germany’s position as a pioneer in the transition to sustainable energy.

The decline in costs for solar power paired with battery storage represents a breakthrough in Germany’s energy sector, especially amid the recent solar power boost during the energy crisis, where the transition from traditional fossil fuels to cleaner alternatives has been a central focus. Historically, conventional power sources such as coal, natural gas, and nuclear energy have dominated electricity markets due to their established infrastructure and relatively stable pricing. However, the rapid advancements in solar technology and energy storage solutions are altering this dynamic, making renewable energy not only environmentally preferable but also economically advantageous.

Several factors contribute to the cost reduction of solar power with battery storage:

  1. Technological Advancements: The technology behind solar panels and battery storage systems has evolved significantly over recent years. Solar panel efficiency has improved, allowing for greater energy generation from smaller installations. Similarly, cheaper batteries have advanced, with reductions in cost and increases in energy density and lifespan. These improvements mean that solar installations can produce more electricity and store it more effectively, enhancing their economic viability.

  2. Economies of Scale: As demand for solar and battery storage systems has grown, manufacturers have scaled up production, leading to economies of scale. This scaling has driven down the cost of both solar panels and batteries, making them more affordable for consumers. As the market for these technologies expands, prices are expected to continue decreasing, further enhancing their competitiveness.

  3. Government Incentives and Policies: Germany’s commitment to renewable energy has been supported by robust government policies and incentives. The country’s Renewable Energy Sources Act (EEG) and other supportive measures, alongside efforts to remove barriers to PV in Berlin that could accelerate adoption, have provided financial incentives for the adoption of solar power and battery storage. These policies have encouraged investment in renewable technologies and facilitated their integration into the energy market, contributing to the overall reduction in costs.

  4. Falling Installation Costs: The cost of installing solar power systems and battery storage has decreased as the industry has matured. Advances in installation techniques, increased competition among service providers, and streamlined permitting processes have all contributed to lower installation costs. This reduction in upfront expenses has made solar with battery storage more accessible and financially attractive to both residential and commercial consumers.

The economic benefits of solar power with battery storage becoming cheaper than conventional power are substantial. For consumers, this shift translates into lower electricity bills and reduced reliance on fossil fuels. Solar installations with battery storage allow households and businesses to generate their own electricity, store it for use during times of low sunlight, and even sell excess power back to the grid, reflecting how solar is reshaping electricity prices in Northern Europe as markets adapt. This self-sufficiency reduces exposure to fluctuating energy prices and enhances energy security.

For the broader energy market, the decreasing cost of solar power with battery storage challenges the dominance of conventional power sources. As renewable energy becomes more cost-effective, it creates pressure on traditional energy providers to adapt and invest in cleaner technologies, including responses to instances of negative electricity prices during renewable surpluses. This shift can accelerate the transition to a low-carbon energy system and contribute to the reduction of greenhouse gas emissions.

Germany’s achievement also has implications for global energy markets. The country’s success in making solar with battery storage cheaper than conventional power serves as a model for other nations pursuing similar energy transitions. As the cost of renewable technologies continues to decline, other countries can leverage these advancements to enhance their own energy systems, reduce carbon emissions, and achieve energy independence amid over 30% of global electricity now from renewables trends worldwide.

The impact of this development extends beyond economics. It represents a significant step forward in addressing climate change and promoting sustainability. By reducing the cost of renewable energy technologies, Germany is accelerating the shift towards a cleaner and more resilient energy system. This progress aligns with the country’s ambitious climate goals and reinforces its role as a leader in global efforts to combat climate change.

Looking ahead, several challenges remain. The integration of renewable energy into existing energy infrastructure, grid stability, and the management of energy storage are all areas that require continued innovation and investment. However, the decreasing cost of solar power with battery storage provides a strong foundation for addressing these challenges and advancing the transition to a sustainable energy future.

In conclusion, the fact that solar power with battery storage in Germany has become cheaper than conventional power is a groundbreaking development with wide-ranging implications. It underscores the technological advancements, economic benefits, and environmental gains associated with renewable energy technologies. As Germany continues to lead the way in clean energy adoption, this achievement highlights the potential for renewable energy to drive global change and reshape the future of energy.

Is tidal energy the surge remote coastal communities need?

BC Tidal Energy Micro-Grids harness predictable tidal currents to replace diesel in remote Indigenous coastal communities, integrating marine renewables, storage, and demand management for resilient off-grid power along Vancouver Island and Haida Gwaii.

 

Key Points

Community-run tidal turbines and storage deliver reliable, diesel-free electricity to remote B.C. coastal communities.

✅ Predictable power from tidal currents reduces diesel dependence

✅ Integrates storage, demand management, and microgrid controls

✅ Local jobs via marine supply chains and community ownership

 

Many remote West Coast communities are reliant on diesel for electricity generation, which poses a number of negative economic and environmental effects.

But some sites along B.C.’s extensive coastline are ideal for tidal energy micro-grids that may well be the answer for off-grid communities to generate clean power, suggested experts at a COAST (Centre for Ocean Applied Sustainable Technologies) virtual event Wednesday.

There are 40 isolated coastal communities, many Indigenous communities, and 32 of them are primarily reliant on diesel for electricity generation, said Ben Whitby, program manager at PRIMED, a marine renewable energy research lab at the University of Victoria (UVic).

Besides being a costly and unreliable source of energy, there are environmental and community health considerations associated with shipping diesel to remote communities and running generators, Whitby said.

“It's not purely an economic question,” he said.

“You've got the emissions associated with diesel generation. There's also the risks of transporting diesel … and sometimes in a lot of remote communities on Vancouver Island, when deliveries of diesel don't come through, they end up with no power for three or four days at a time.”

The Heiltsuk First Nation, which suffered a 110,000-litre diesel spill in its territorial waters in 2016, is an unfortunate case study for the potential environmental, social, and cultural risks remote coastal communities face from the transport of fossil fuels along the rough shoreline.

A U.S. barge hauling fuel for coastal communities in Alaska ran aground in Gale Pass, fouling a sacred and primary Heiltsuk food-harvesting area.

There are a number of potential tidal energy sites near off-grid communities along the mainland, on both sides of Vancouver Island, and in the Haida Gwaii region, Whitby said.

Tidal energy exploits the natural ebb and flow of the coast’s tidal water using technologies like underwater kite turbines to capture currents, and is a highly predictable source of renewable energy, he said.

Micro-grids are self-reliant energy systems drawing on renewables from ocean, wave power resources, wind, solar, small hydro, and geothermal sources.

The community, rather than a public utility like BC Hydro, is responsible for demand management, storage, and generation with the power systems running independently or alongside backup fuel generators — offering the operators a measure of energy sovereignty.

Depending on proximity, cost, and renewable solutions, tidal energy isn’t necessarily the solution for every community, Whitby noted, adding that in comparison to hydro, tidal energy is still more expensive.

However, the best candidates for tidal energy are small, off-grid communities largely dependent on costly fossil fuels, Whitby said.

“That's really why the focus in B.C. is at a smaller scale,” he said.

“The time it would take (these communities) to recoup any capital investment is a lot shorter.

“And the cost is actually on a par because they're already paying a significant amount of money for that diesel-generated power.”

Lisa Kalynchuk, vice-president of research and innovation at UVic, said she was excited by the possibilities associated with tidal power, not only in B.C., but for all of Canada’s coasts.

“Canada has approximately 40,000 megawatts available on our three coastlines,” Kalynchuk said.

“Of course, not all this power can be realized, but it does exist, so that leads us to the hard part — tapping into this available energy and delivering it to those remote communities that need it.”

Challenges to establishing tidal power include the added cost and complexity of construction in remote communities, the storage of intermittent power for later use, the economic model, though B.C.’s streamlined regulatory process may ease approvals, the costs associated with tidal power installations, and financing for small communities, she said.

But smaller tidal energy projects can potentially set a track record for more nascent marine renewables, as groups like Marine Renewables Canada pivot to offshore wind development, at a lower cost and without facing the same social or regulatory resistance a large-scale project might face.

A successful tidal energy demo project was set up using a MAVI tidal turbine in Blind Channel to power a private resort on West Thurlow Island, part of the outer Discovery Islands chain wedged between Vancouver Island and the mainland, Whitby said.

The channel’s strong tidal currents, which routinely reach six knots and are close to the marina, proved a good site to test the small-scale turbine and associated micro-grid system that could be replicated to power remote communities, he said.

The mooring system, cable, and turbine were installed fairly rapidly and ran through the summer of 2017. The system is no longer active as provincial and federal funding for the project came to an end.

“But as a proof of concept, we think it was very successful,” Whitby said, adding micro-grid tidal power is still in the early stages of development.

Ideally, the project will be revived with new funding, so it can continue to act as a test site for marine renewable energy and to showcase the system to remote coastal communities that might want to consider tidal power, he said.

In addition to harnessing a local, renewable energy source and increasing energy independence, tidal energy micro-grids can fuel employment and new business opportunities, said Whitby.

The Blind Channel project was installed using the local supply chain out of nearby Campbell River, he said.

“Most of the vessels and support came from that area, so it was all really locally sourced.”

Funding from senior levels of government would likely need to be provided to set up a permanent tidal energy demonstration site, with recent tidal energy investments in Nova Scotia offering a model, or to help a community do case studies and finance a project, Whitby said.

Both the federal and provincial governments have established funding streams to transition remote communities away from relying on diesel.

But remote community projects funded federally or provincially to date have focused on more established renewables, such as hydro, solar, biomass, or wind.

The goal of B.C.’s Remote Community Energy Strategy, part of the CleanBC plan and aligned with zero-emissions electricity by 2035 targets across Canada, is to reduce diesel use for electricity 80 per cent by 2030 by targeting 22 of the largest diesel locations in the province, many of which fall along the coast.

The province has announced a number of significant investments to shift Indigenous coastal communities away from diesel-generated electricity, but they predominantly involve solar or hydro projects.

A situation that’s not likely to change, as the funding application guide in 2020 deemed tidal projects as ineligible for cash.

Yet, the potential for establishing tidal energy micro-grids in B.C. is good, Kalynchuk said, noting UVic is a hub for significant research expertise and several local companies, including ocean and river power innovators working in the region, are employing and developing related service technologies to install and maintain the systems.

“It also addresses our growing need to find alternative sources of energy in the face of the current climate crisis,” she said.

“The path forward is complex and layered, but one essential component in combating climate change is a move away from fossil fuels to other sources of energy that are renewable and environmentally friendly.”
