Vehicle-to-grid could be ‘capacity on wheels’ for electricity networks

Nova Scotia Biomass Energy faces scrutiny as hydropower from Muskrat Falls via the Maritime Link increases, raising concerns over carbon emissions, biodiversity, ratepayer costs, and efficiency versus district heating in the province's renewable mix.

Key Points

Electricity from wood chips and waste wood in Nova Scotia, increasingly questioned as hydropower from the Maritime Link grows.

✅ Hydropower deliveries reduce need for biomass on the grid

✅ Biomass is inefficient, costly, and impacts biodiversity

✅ District heating offers better use of forestry residuals

The Ecology Action Centre's senior wilderness coordinator is calling on the Nova Scotia government to reduce the use of biomass to generate electricity now that more hydroelectric power is flowing into the province.

In 2020, the government of the day signed a directive for Nova Scotia Power to increase its use of biomass to generate electricity, including burning more wood chips, waste wood and other residuals from the forest industry. At the time, power from Muskrat Falls hydroelectric project in Labrador was not flowing into the province at high enough levels to reach provincial targets for electricity generated by renewable resources.

In recent months, however, the Maritime Link from Muskrat Falls has delivered Nova Scotia's full share of electricity, and, in some cases, even more, as the province also pursues Bay of Fundy tides projects to diversify supply.

Ray Plourde with the Ecology Action Centre said that should be enough to end the 2020 directive.

Biomass is "bad on a whole lot of levels," said Plourde, including its affects on biodiversity and the release of carbon into the atmosphere, he said. The province's reliance on waste wood as a source of fuel for electricity should be curbed, said Plourde.

"It's highly inefficient," he said. "It's the most expensive electricity on the power grid for ratepayers."

A spokesperson for the provincial Natural Resources and Renewables Department said that although the Maritime Link has "at times" delivered adequate electricity to Nova Scotia, "it hasn't done so consistently," a context that has led some to propose an independent planning body for long-term decisions.

"These delays and high fossil fuel prices mean that biomass remains a small but important component of our renewable energy mix," Patricia Jreiga said in an email, even as the province plans to increase wind and solar projects in the years ahead.

But to Plourde, that explanation doesn't wash.

The Nova Scotia Utility and Review Board recently ruled that Nova Scotia Power could begin recouping costs of the Maritime Link project from ratepayers. As for the rising cost of fossil fuels, Ploude noted that the inefficiency of biomass means there's no deal to be had using it as a fuel source.

"Honestly, that sounds like a lot of obfuscation," he said of the government's position.

No update on district heating plans
At the time of the directive, government officials said the increased use of forestry byproducts at biomass plants in Point Tupper and Brooklyn, N.S., including the nearby Port Hawkesbury Paper mill, would provide a market for businesses struggling to replace the loss of Northern Pulp as a customer. Brooklyn Power has been offline since a windstorm damaged that plant in February, however. Repairs are expected to be complete by the end of the year or early 2023.

Ploude said a better use for waste wood products would be small-scale district heating projects, while others advocate using more electricity for heat in cold regions.

Although the former Liberal government announced six public buildings to serve as pilot sites for district heating in 2020, and a list of 100 other possible buildings that could be converted to wood heat, there have been no updates.

"Currently, we're working with several other departments to complete technical assessments for additional sites and looking at opportunities for district heating, but no decisions have been made yet," provincial spokesperson Steven Stewart said in an email.

Ottawa Electricity Consumption Drop reflects COVID-19 impacts, with Hydro Ottawa and IESO reporting 10-12% lower demand, delayed morning peaks, and shifted weekend peak to 4 p.m., alongside provincial time-of-use rate relief.

Key Points

A 10-12% decline in Ottawa's electricity demand during COVID-19, with later morning peaks and weekend peak at 4 p.m.

✅ Weekday demand down 11%; weekends down 10% vs April 2019.

✅ Morning peak delayed about 4 hours; 6 a.m. usage down 17%.

✅ Weekend peak moved from 7 p.m. to 4 p.m.; rate relief ongoing.

Ottawa residents may be spending more time at home, with residential electricity use up even as the city’s overall energy use has dropped during the COVID-19 pandemic.

Hydro Ottawa says there was a 10-to-11 per cent drop in electricity consumption in April, with the biggest decline in electricity usage happening early in the morning, a pattern echoed by BC Hydro findings in its province.

Statistics provided to CTV News Ottawa show average hourly energy consumption in the City of Ottawa dropped 11 per cent during weekdays, mirroring Manitoba Hydro trends reported during the pandemic, and a 10 per cent decline in electricity consumption on weekends.

The drop in energy consumption came as many businesses in Ottawa closed their doors due to the COVID-19 measures and physical distancing guidelines.

“Based on our internal analysis, when comparing April 2020 to April 2019, Hydro Ottawa observed a lower, flatter rise in energy use in the morning, with peak demand delayed by approximately four hours.” Hydro Ottawa said in a statement to CTV News Ottawa.

“Morning routines appear to have the largest difference in energy consumption, most likely as a result of a collective slower pace to start the day as people are staying home.”

Hydro Ottawa says overall, there was an 11 per cent average hourly reduction in energy use on weekdays in April 2020, compared to April 2019. The biggest difference was the 6 a.m. hour, with a 17 per cent decrease.

On weekends, the average electricity usage dropped 10 per cent in April, compared to April 2019. The biggest difference was between 7 a.m. and 8 a.m., with a 13 per cent drop in hydro usage.

Hydro Ottawa says weekday peak continues to be at 4 p.m., while on weekends the peak has shifted from 7 p.m. before the pandemic to 4 p.m. now, though Hydro One has not cut peak rates for self-isolating customers.

The Independent Electricity System Operator says across Ontario, there has been a 10 to 12 per cent drop in energy consumption during the pandemic, a trend reflected in province-wide demand data that is the equivalent to half the demand of Toronto.

The Ontario Government has provided emergency electricity rate relief during the COVID-19 pandemic. Residential and small business consumers on time-of-use pricing, and later ultra-low overnight options, will continue to pay one price no matter what time of day the electricity is consumed until the end of May.

Scotland Wind Energy delivered record renewable power as wind turbines and farms generated 9,831,320 MWh in H1 2019, supplying clean electricity for every home twice and supporting northern England, according to WWF data.

Key Points

Term for Scotland's wind power output, highlighting 2019 records, clean electricity, and progress on decarbonization.

✅ 9,831,320 MWh generated Jan-Jun 2019 by wind farms

✅ Enough to power 4.47 million homes twice in that period

✅ Advances decarbonization and 2030 renewables, 2050 net-zero goals

Wind turbines in Scotland produced enough electricity in the first half of 2019, reflecting periods when wind led the power mix across the UK, to power every home in the country twice over, according to new data by the analytics group WeatherEnergy. The wind farms generated 9,831,320 megawatt-hours between January and June, as the UK set a wind generation record in comparable periods, equal to the total electricity consumption of 4.47 million homes during that same period.

The electricity generated by wind in early 2019 is enough to power all of Scotland’s homes, as well as a large portion of northern England’s, highlighting how wind and solar exceeded nuclear in the UK in recent milestones as well, and events such as record UK output during Storm Malik underscore this capacity.

“These are amazing figures,” Robin Parker, climate and energy policy manager at WWF, which highlighted the new data, said in a statement. “Scotland’s wind energy revolution is clearly continuing to power ahead, as wind became the UK’s main electricity source in a recent first. Up and down the country, we are all benefitting from cleaner energy and so is the climate.”

Scotland currently has a target of generating half its electricity from renewables by 2030, a goal buoyed by milestones like more UK electricity from wind than coal in 2016, and decarbonizing its energy system almost entirely by 2050. Experts say the latest wind energy data shows the country could reach its goal far sooner than originally anticipated, especially with complementary technologies such as tidal power in Scottish waters gaining traction.

Manitoba Hydro unpaid leave plan offers unpaid days off to curb workforce costs amid COVID-19, avoiding temporary layoffs and pay cuts, targeting $5.7M savings through executive, manager, and engineer participation, with union options under discussion.

Key Points

A cost-saving measure offering unpaid days off to avert layoffs and pay cuts, targeting $5.7M savings amid COVID-19.

✅ 3 unpaid days for executives, managers, engineers

✅ Targets $5.7M total; $1.4M from non-union staff

✅ Avoids about 240 layoffs over a four-month period

The Manitoba government's Crown energy utility is offering workers unpaid days off as an alternative to temporary layoffs or pay cuts, even as residential electricity use rises due to more working from home.

In an email to employees, Manitoba Hydro president Jay Grewal says executives, managers, and engineers will take three unpaid days off before the fiscal year ends next March.

She says similar options are being discussed with other employee groups, which are represented by unions, as the Saskatchewan COVID-19 crisis reshaped workforces across the Prairies.

The provincial government ordered Manitoba Hydro to reduce workforce costs during the COVID-19 pandemic, as some power operators considered on-site staffing plans, and at one point the utility said it was looking at 600 to 700 temporary layoffs.

The organization said it’s looking for targeted savings of $5.7 million, down from $11 million previously estimated, while peers like BC Hydro’s Site C began reporting COVID-19 updates.

A spokesperson for Manitoba Hydro said non-unionized staff taking three days of unpaid leave will save $1.4 million of the $5.7 million savings.

“Three days of unpaid leave for every employee would eliminate layoffs entirely,” the spokesperson said in an email. “For comparison, approximately 240 layoffs would have to occur over a four-month period, while measures like Alberta's worker transition fund aim to support displaced workers, to achieve savings of $4.3 million.”

Grewal says the unpaid days off were a preferred option among the executives, managers, and engineers in an industry that recently saw a Hydro One worker injury case.

She says unions representing the other workers have been asked to respond by next Wednesday.

Florida Hurricane Irma Power Outages strain the grid as utilities plan rebuilds; FPL and Duke Energy deploy crews to restore transmission lines, substations, and service amid flooding, storm surge, and widespread disruptions statewide.

Key Points

Large-scale post-storm power losses in Florida requiring grid rebuilds, thousands of crews, and phased restoration.

✅ Utilities prioritize plants, transmission, substations, then critical facilities

✅ 50,000-60,000 workers mobilized; bucket trucks wait for safe winds

✅ Remote rerouting and hardening aid faster restoration amid flooding

Parts of Florida could be without electricity for more than a week, as damage from Hurricane Irma will require a complete rebuild of portions of the electricity grid, utility executives said on Monday.

Irma has knocked out power to 6.5 million Florida electricity customers, or nearly two-thirds of the state, since making landfall this weekend. In major areas such as Miami-Dade, 74 percent of the county was without power, according to Florida's division of emergency management.

Getting that power back online may require the help of 50,000 to 60,000 workers from all over the United States and Canadian power crews as well, according to Southern Company CEO and Chairman Thomas Fanning. He is also co-chair of the Electricity Subsector Coordinating Council, which coordinates the utility industry and government response to disasters and cyberthreats.

While it is not uncommon for severe storms to down power lines and damage utility poles, Irma's heavy winds and rain batted some of the state's infrastructure to the ground, Fanning said.

"'Restore' may not capture the full sense of where we are. For the very hard impacted areas, I think you're in a 'rebuild' area," he told CNBC's "Squawk Box."

"That's a big deal. People need to understand this is going to take perhaps weeks, not days, in some areas," Fanning said.

Parts of northern Florida, including Jacksonville, experienced heavy flooding, which will temporarily prevent crews from accessing some areas.

Duke Energy, which serves 1.8 million customers in parts of central and northwestern Florida, is trying to restore service to 1.2 million residences and businesses.

Florida Power & Light Company, which provides power to an estimated 4.9 million accounts across the state, had about 3.5 million customers without electricity as of Monday afternoon, said Rob Gould, vice president and chief communications officer at FPL.

The initial damage assessments suggest power can be restored to parts of the state's east coast in just days, but some of the west coast will require rebuilding that could stretch out for weeks, Gould told CNBC's "Power Lunch."

"This is not a typical restoration that you're going to see. We actually for the first time in our company history have our entire 27,000-square-mile, 35-county territory under assault by Irma," he said.

FPL said it would first repair any damage to power plants, transmission lines and substations as part of its massive response to Irma, then prioritize critical facilities such as hospitals and water treatment plants. The electricity company would then turn its attention to areas that are home to supermarkets, gas stations and other community services.

Florida utilities invested billions into their systems after devastating hurricane seasons in 2004 and 2005 in order to make them more resilient and easier to restore after a storm. Irma, which ranked among the most powerful storms in the Atlantic, has nevertheless tested those systems.

The upgrades have allowed FPL to automatically reroute power and address about 1.5 million outages, Gould said. The company strategically placed 19,500 restoration workers before the storm hit, but it cannot use bucket trucks to fix power lines until winds die down, he said.

Some parts of Florida's distribution system — the lines that deliver electricity from power plants to businesses and residences — run underground. However, the state's long coastline and the associated danger of storm surge and seawater incursion make it impractical to run lines beneath the surface in some areas.

Duke Energy has equipped 28 percent of its system with smart grid technology to reroute power remotely, according to Harry Sideris, Duke's state president for Florida. He said the company would continue to build out that capability in the future.

Duke deployed more than 9,000 linesmen and support crew members to Irma-struck areas, but cannot yet say how long some customers will be without power.

Separately, Gulf Power crews reported restoring service to more than 32,000 customers.

"At this time we do not know the exact restoration times. However, we're looking at a week or longer from the first look at the widespread damage that we had," Sideris told CNBC's "Closing Bell."

FPL said on Monday it was doing final checks before bringing back nuclear reactors that were powered down as Hurricane Irma hit Florida.

"We are in the process now of doing final checks on a few of them; we will be bringing those up," FPL President and CEO Eric Silagy told reporters.

California Community Choice Aggregators are reshaping electricity markets with renewable energy, solar and wind sourcing, competitive rates, and customer choice, challenging PG&E, SDG&E, and Southern California Edison while advancing California's clean power goals.

Key Points

Local governments that buy power, often cleaner and cheaper, while utilities handle delivery and billing.

✅ Offer higher renewable mix than utilities at competitive rates

✅ Utilities retain transmission and billing responsibilities

✅ Rapid expansion threatens IOU market share across California

Nearly 2 million electricity customers in California may not know it, but they’re part of a revolution. That many residents and businesses are getting their power not from traditional utilities, but via new government-affiliated entities known as community choice aggregators. The CCAs promise to deliver electricity more from renewable sources, such as solar and wind, even as California exports its energy policies across Western states, and for a lower price than the big utilities charge.

The customers may not be fully aware they’re served by a CCA because they’re still billed by their local utility. But with more than 1.8 million accounts now served by the new system and more being added every month, the changes in the state’s energy system already are massive.

Faced for the first time with real competition, the state’s big three utilities have suddenly become havens of innovation. They’re offering customers flexible options on the portion of their power coming from renewable energy, amid a broader review to revamp electricity rates aimed at cleaning the grid, and they’re on pace to increase the share of power they get from solar and wind power to the point where they are 10 years ahead of their deadline in meeting a state mandate.

#google#

But that may not stem the flight of customers. Some estimates project that by late this year, more than 3 million customers will be served by 20 CCAs, and that over a longer period, Pacific Gas & Electric, Southern California Edison, and San Diego Gas & Electric could lose 80% of their customers to the new providers.

Two big customer bases are currently in play: In Los Angeles and Ventura counties, a recently launched CCA called the Clean Power Alliance is hoping by the end of 2019 to serve nearly 1 million customers. Unincorporated portions of both counties and 29 municipalities have agreed in principle to join up.

Meanwhile, the city of San Diego is weighing two options to meet its goal of 100% clean power by 2035, as exit fees are being revised by the utilities commission: a plan to be submitted by SDG&E, or the creation of a CCA. A vote by the City Council is expected by the end of this year. A city CCA would cover 1.4 million San Diegans, accounting for half SDG&E’s customer demand, according to Cody Hooven, the city’s chief sustainability officer.

Don’t expect the big companies to give up their customers without a fight. Indeed, battle lines already are being drawn at the state Public Utilities Commission, where a recent CPUC ruling sided with a community energy program over SDG&E, and local communities.

“SDG&E is in an all-out campaign to prevent choice from happening, so that they maintain their monopoly,” says Nicole Capretz, who wrote San Diego’s climate action plan as a city employee and now serves as executive director of the Climate Action Campaign, which supports creation of the CCA.

California is one of seven states that have legalized the CCA concept, even as regulators weigh whether the state needs more power plants to ensure reliability. (The others are New York, New Jersey, Massachusetts, Ohio, Illinois and Rhode Island.) But the scale of its experiment is likely to be the largest in the country, because of the state’s size and the ambition of its clean-power goal, which is for 50% of its electricity to be generated from renewable sources by 2030.

California created its system via legislative action in 2002. Assembly Bill 117 enabled municipalities and regional governments to establish CCAs anywhere that municipal power agencies weren’t already operating. Electric customers in the CCA zones were automatically signed up, though they could opt out and stay with their existing power provider. The big utilities would retain responsibility for transmission and distribution lines.

The first CCA, Marin Clean Energy, began operating in 2010 and now serves 470,000 customers in Marin and three nearby counties.

The new entities were destined to come into conflict with the state’s three big investor-owned utilities. Their market share already has fallen to about 70%, from 78% as recently as 2010, and it seems destined to keep falling. In part that’s because the CCAs have so far held their promise: They’ve been delivering relatively clean power and charging less.

The high point of the utilities’ hostility to CCAs was the Proposition 16 campaign in 2009. The ballot measure was dubbed the “Taxpayers Right to Vote Act,” but was transparently an effort to smother CCAs in the cradle. PG&E drafted the measure, got it on the ballot, and contributed all of the $46.5 million spent in the unsuccessful campaign to pass it.

As recently as last year, PG&E and SDG&E were lobbying in the legislature for a bill that would place a moratorium on CCAs. The effort failed, and hasn’t been revived this year.

Rhetoric similar to that used by PG&E against Marin’s venture has surfaced in San Diego, where a local group dubbed “Clear the Air” is fighting the CCA concept by suggesting that it could be financially risky for local taxpayers and questioning whether it will be successful in providing cleaner electricity. Whether Clear the Air is truly independent of SDG&E’s parent, Sempra Energy, is questionable, as at least two of its co-chairs are veteran lobbyists for the company.

SDG&E spokeswoman Helen Gao says the utility supports “customers’ right to choose an energy provider that best meets their needs” and expects to maintain a “cooperative relationship” with any provider chosen by the city.
