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.

California Grid Modernization Funding will upgrade transmission and distribution, boost grid resilience, enable renewable energy integration, expand energy storage, and deploy smart grid controls statewide with over $500 million in federal infrastructure investment.

Key Points

Federal support to harden California's grid, integrate renewables, add storage, and deploy smart upgrades for reliability.

✅ Strengthens transmission and distribution for wildfire and heat resilience

✅ Integrates solar and wind with storage and advanced grid controls

✅ Deploys smart meters, DER management, and modern cybersecurity

California has recently been awarded over $500 million in federal funds to significantly improve and modernize its power grid. This substantial investment marks a pivotal step in addressing the state’s ongoing energy challenges, enhancing grid resilience, and supporting its ambitious climate goals. The funding, announced by federal and state officials, is set to bolster California’s efforts to upgrade its electrical infrastructure, integrate renewable energy sources, and ensure a more reliable and sustainable energy system for its residents.

California's power grid has faced numerous challenges in recent years, including extreme weather events, high energy demand, and an increasing reliance on renewable energy sources. The state's electrical infrastructure has struggled to keep pace with these demands, leading to concerns about reliability, efficiency, and the capacity to handle new energy technologies. The recent federal funding is a critical component of a broader strategy to address these issues and prepare the grid for future demands.

The $500 million in federal funds is part of a larger initiative to support energy infrastructure projects across the United States, including a Washington state grant that strengthens regional infrastructure. The investment aims to modernize aging grid systems, improve energy efficiency, and enhance the integration of renewable energy sources. For California, this funding represents a significant opportunity to address several key areas of concern in its power grid.

One of the primary objectives of the funding is to enhance the resilience of the power grid. California has experienced a series of extreme weather events, including wildfires and heatwaves, driven in part by climate change impacts across the U.S., which have put considerable strain on the electrical infrastructure. The new investment will support projects designed to strengthen the grid’s ability to withstand and recover from these events. This includes upgrading infrastructure to make it more robust and less susceptible to damage from natural disasters.

Another key focus of the funding is the integration of renewable energy sources. California is a leader in the adoption of solar and wind energy, and the state has set ambitious goals for increasing its use of clean energy. However, integrating these variable energy sources into the grid presents technical challenges, including ensuring a stable and reliable power supply. The federal funds will be used to develop and deploy advanced technologies that can better manage and store renewable energy, such as battery storage systems, improving the overall efficiency and effectiveness of the grid.

In addition to resilience and renewable integration, the funding will also support efforts to modernize grid infrastructure. This includes upgrading transmission and distribution systems, implementing smarter electricity infrastructure and smart grid technologies, and enhancing grid management and control systems. These improvements are essential for creating a more flexible and responsive power grid that can meet the evolving needs of California’s energy landscape.

The investment in grid modernization also aligns with California’s broader climate goals. The state has set targets to reduce greenhouse gas emissions and increase the use of clean energy sources as it navigates keeping the lights on during its energy transition. By improving the power grid and supporting the integration of renewable energy, California is making progress toward achieving these goals while also creating jobs and stimulating economic growth.

The allocation of federal funds comes at a crucial time for California. The state has faced significant challenges in recent years, including power outages, energy reliability issues, and increasing energy costs that make repairing California's grid especially complex today. The new funding is expected to address many of these concerns by supporting critical infrastructure improvements and ensuring that the state’s power grid can meet current and future demands.

Federal and state officials have expressed strong support for the funding and its potential impact. The investment is seen as a major step forward in creating a more resilient and sustainable energy system for California. It is also expected to serve as a model for other states facing similar challenges in modernizing their power grids and integrating renewable energy sources.

The federal funding is part of a broader push to address infrastructure needs across the country. The Biden administration has prioritized investment in energy infrastructure, including a $34 million DOE initiative supporting grid improvements, as part of its broader agenda to combat climate change and build a more sustainable economy. The funding for California’s power grid is a reflection of this commitment and an example of how federal resources can support state and local efforts to improve infrastructure and address pressing energy challenges.

In summary, California’s receipt of over $500 million in federal funds represents a significant investment in the state’s power grid. The funding will support efforts to enhance grid resilience, integrate renewable energy sources, and modernize infrastructure. As California continues to face challenges related to extreme weather, energy reliability, and climate goals, this investment will play a crucial role in building a more reliable, efficient, and sustainable energy system. The initiative also highlights the importance of federal support in addressing infrastructure needs and advancing environmental and economic goals.

Hydro One COVID-19 Rate Relief responds to time-of-use pricing, peak rates, and Ontario Energy Board rules as residents stay home, offering a Pandemic Relief Fund, flexible payments, and support for electricity bills amid off-peak adjustments.

Key Points

Hydro One's COVID-19 rate relief includes payment flexibility and hardship aid to ease time-of-use bill burdens.

✅ Advocates flexibility on time-of-use and peak rate impacts

✅ Pandemic Relief Fund offers aid and payment options

✅ OEB sets prices; utilities relay concerns and support

Hydro One says it is listening to requests by self-isolating residents for reduced kilowatt hour peak rates during the day when most people are home riding out the COVID-19 pandemic.

Peak rates of 20.8 cents per kw/h are twice as high from 7 a.m. to 7 p.m. – except weekends – than off-peak rates of 10.1 cents per kw/h and set by the Ontario Energy Board and not electricity providers such as Hydro One and Elexicon (formerly Veridian).

Frustrated electrical customers have signed their John Henry’s more than 50,000 times to a change.org petition demanding Hydro One temporarily slash rates for those already struggling with work closures and loss of income amid concerns about a potential recovery rate that could raise bills.

Alex Stewart, media relations spokesman for Hydro One, said the corporation is working toward a solution.

“While we are regulated to adhere to time-of-use pricing by the Ontario Energy Board, we’ve heard the concerns about time-of-use pricing and the idea of a fixed COVID-19 hydro rate as many of our customers will stay home to stop the spread of COVID-19,” Stewart told The Intelligencer.

“We continue to advocate for greater choice during this difficult time and are working with everyone in the electricity sector to ensure our customers are heard.”

Stewart said the electricity provider is reaching out to customers to help them during a difficult self-isolating and social distancing period in other ways to bring financial relief.

For example, new hardship measures are now in play by Hydro One to give customers some relief from ballooning electricity bills.

“This is a difficult time for everyone. Hydro One has launched a new Pandemic Relief Fund to support customers affected by the novel coronavirus COVID-19. As part of our commitment to customers, we will offer financial assistance, as well as increased payment flexibility, to customers experiencing hardship,” Stewart said.

“Hydro One is also extending its Winter Relief program to halt disconnections and reconnections to customers experiencing hardship during the coldest months of the year. This is about doing the right thing and offering flexibility to our customers so they have peace of mind and can concentrate on what matters most – keeping their loved ones safe.”

Stewart said customers having difficult times can visit the company’s website for more details at www.HydroOne.com/ReliefFund.

Elexicon Energy, meanwhile, said earlier the former Veridian company is passing along concerns to the OEB but otherwise can’t lower the rates unless directed to do so, as occurred when the province set off-peak pricing temporarily.

Chris Mace, Elexicon corporate communications spokesperson, said, “We don’t have the authority to do that.

“The Ontario Energy Board sets the energy prices. This is in the Ministry of Energy’s hands. We at Elexicon, along with other local distribution companies (LDC), have shared this feedback with the ministry and OEB to come up with some sort of solution or alternative. But this is out of our hands. We can’t shift anything.”

He suggested residents can shift the use of higher-drawing electrical appliances to early morning before 7 or in the evening after 7 p.m. when ultra-low overnight rates may apply.

Families may want to be “mindful whether it be cooking or laundry and so on and holding off on doing those until off-peak hours take effect. We are hearing customers and we have passed along those concerns to the ministry and the OEB.”

Hydro One power tips

Certain electrical uses in the home consumer more power than others, as reflected in Ontario’s electricity cost allocation approach:

62 per cent goes to space heating
19 per cent goes to water heaters
13 per cent goes to appliances
2 per cent goes to space cooling

Hydro-Quebec back-billing arises from analogue meter errors and estimated consumption, leading to arrears for electricity usage; disputes over access, payment plans, and potential power diversion reviews can impact cottage owners near Gatineau.

Key Points

Hydro-Quebec back-billing recovers underbilled electricity from analogue meter errors or prolonged estimated use.

✅ Triggered by inaccurate analogue meters or missed readings

✅ Based on actual usage versus prior estimated consumption

✅ Payment plans may spread arrears; theft checks may adjust

A relaxing lakefront cottage has become a powerful source of stress for an Ottawa woman who Hydro-Quebec is charging $5,300 to cover what it says are years of undercharging for electricity usage.

The utility said an old analogue power meter is to blame for years of inaccurate electricity bills for the summer getaway near Gatineau, Que.

Separate from individual billing issues, Hydro-Quebec has also reported pandemic-related losses earlier this year.

Owner Jan Hodgins does not think she should be held responsible for the mistake, nor does she understand how her usage could have surged over the years.

“I’m very hydro conscious, because I was raised that way. When you left a room, you always turned the light out,” she told CTV Montreal on Wednesday, relating her shock after receiving some hefty bills from Hydro-Quebec on Sept. 22.

Hodgins said she mainly uses the cottage on weekends, does not heat the place when she is not there, and does not use a washer or dryer, to keep her energy footprint as small as possible. She’s owned the cottage for 14 years, during which she says her monthly bill has hovered around $40.

Hydro-Quebec said it has not had an accurate reading of her usage for several years, relying instead on consumption estimates to determine what she pays. The company recently reviewed her energy consumption back to 2014, and found their estimates were not accurate.

“In the past, she was consuming about 10 to 15 kilowatt hours per day. This summer she was more around 40 kilowatt hours per day,” Marc-Antoine Pouliot with Hydro-Quebec told CTV Ottawa.

Hodgins said that means her regular bill will now be more than twice the $200 her neighbours are paying for hydro each month, even with peak hydro rates in place.

Hydro-Quebec said it will correct the bill if its technicians discover that someone is illegally diverting power nearby.

Hodgins said it’s not her fault that technicians did not check her meter in person, and chose to rely on inaccurate estimates. Pouliot argues that reaching her cottage was too difficult.

“There was too much snow. There were conditions during the winter disconnection ban period, and the consequence was that people, our workers, were not able to reach the meter,” he said.

Hydro-Quebec said it is willing to stretch out the debt into monthly payments over a year, which Hodgins said amount to $440 per month on top of her regular bill.

Utilities also caution customers about scammers threatening shutoffs during billing disputes.

“I’m on a fixed income. I don’t have that kind of money. I’m completely distraught,” she said. “I don’t know what I’m going to do.”

UK Electricity Grid Investment underpins net zero, reinforcing transmission and distribution networks to integrate wind, solar, EV charging, and heat pumps, while Ofgem balances investor returns, debt risks, price controls, resilience, and consumer bills.

Key Points

Capital to reinforce grids for net zero, integrating wind, solar, EVs and heat pumps while balancing returns and bills.

✅ 170bn-210bn GBP by 2050 to reinforce cables, pylons, capacity.

✅ Ofgem to add investability metric while protecting consumers.

✅ Integrates wind, solar, EVs, heat pumps; manages grid resilience.

Prime Minister Sunak's recent upgrade to his home's electricity grid, designed to power his heated swimming pool, serves as a microcosm of a much larger challenge facing the UK: transforming the nation's entire electricity network for net zero emissions, amid Europe's electrification push across the continent.

This transition requires a monumental £170bn-£210bn investment by 2050, earmarked for reinforcing and expanding onshore cables and pylons that deliver electricity from power stations to homes and businesses. This overhaul is crucial to accommodate the planned switch from fossil fuels to clean energy sources - wind and solar farms - powering homes with electric cars, as EV demand on the grid rises, and heat pumps.

The UK government's Climate Change Committee warns of potentially doubled electricity demand by 2050, the target date for net zero, even though managing EV charging can ease local peaks. This translates to a significant financial burden for companies like National Grid, SSE, and Scottish Power who own the main transmission networks and some regional distribution networks.

Balancing investor needs for returns and ensuring affordable energy bills for consumers presents a delicate tightrope act for regulators like Ofgem. The National Audit Office criticized Ofgem in 2020 for allowing network owners excessive returns, prompting concerns about potential bill hikes, especially after lessons from 2021 reshaped market dynamics.

Think-tank Common Wealth reported that distribution networks paid out a staggering £3.6bn to their owners between 2017 and 2021, raising questions about the balance between profitability and affordability, amid UK EV affordability concerns among consumers.

However, Ofgem acknowledges the need for substantial investment to finance network upgrades, repairs, and the clean energy transition. To this end, they are considering incorporating an "investability" metric, recognizing how big battery rule changes can erode confidence elsewhere, in the next price controls for transmission networks, ensuring these entities remain attractive for equity fundraising without overburdening consumers.

This proposal, while welcomed by the industry, has drawn criticism from consumer advocacy groups like Citizens Advice, who fear it could contribute to unfairly high bills. With energy bills already hitting record highs, public trust in the net-zero transition hinges on ensuring affordability.

High debt levels and potential credit rating downgrades further complicate the picture, potentially impacting companies' ability to raise investment funds. Ofgem is exploring measures to address this, such as stricter debt structure reporting requirements for regional distribution companies.

Lawrence Slade, CEO of the Energy Networks Association, emphasizes the critical role of investment in achieving net zero. He highlights the need for "bold" policies and regulations that balance ambitious goals with investor confidence and ensure efficient resource allocation, drawing on B.C.'s power supply challenges as a cautionary example.

The challenge lies in striking a delicate balance between attracting investment, ensuring network resilience, and maintaining affordable energy bills. As Andy Manning from Citizens Advice warns, "Without public confidence, net zero won't be delivered."

The UK's journey to net zero hinges on navigating this complex landscape. By carefully calibrating regulations, fostering investor confidence, and prioritizing affordability, the country can ensure its electricity grid is not just robust enough to power heated swimming pools, but also a thriving green economy for all.

Hourly Electricity Emissions Tracking maps grid balancing areas, embodied emissions, and imports/exports, revealing carbon intensity shifts across PJM, ERCOT, and California ISO, and clarifying renewable energy versus coal impacts on health and climate.

Key Points

An hourly method tracing generation, flows, and embodied emissions to quantify carbon intensity across US balancing areas.

✅ Hourly traces of imports/exports and generation mix

✅ Consumption-based carbon intensity by balancing area

✅ Policy insights for renewables, coal, health costs

In the United States, electricity generation accounts for nearly 30% of our carbon emissions. Some states have responded to that by setting aggressive renewable energy standards; others are hoping to see coal propped up even as its economics get worse. Complicating matters further is the fact that many regional grids are integrated, and as America goes electric the stakes grow, meaning power generated in one location may be exported and used in a different state entirely.

Tracking these electricity exports is critical for understanding how to lower our national carbon emissions. In addition, power from a dirty source like coal has health and environment impacts where it's produced, and the costs of these aren't always paid by the parties using the electricity. Unfortunately, getting reliable figures on how electricity is produced and where it's used is challenging, even for consumers trying to find where their electricity comes from in the first place, leaving some of the best estimates with a time resolution of only a month.

Now, three Stanford researchers—Jacques A. de Chalendar, John Taggart, and Sally M. Benson—have greatly improved on that standard, and they have managed to track power generation and use on an hourly basis. The researchers found that, of the 66 grid balancing areas within the United States, only three have carbon emissions equivalent to our national average, and they have found that imports and exports of electricity have both seasonal and daily changes. de Chalendar et al. discovered that the net results can be substantial, with imported electricity increasing California's emissions/power by 20%.

Hour by hour
To figure out the US energy trading landscape, the researchers obtained 2016 data for grid features called balancing areas. The continental US has 66 of these, providing much better spatial resolution on the data than the larger grid subdivisions. This doesn't cover everything—several balancing areas in Canada and Mexico are tied in to the US grid—and some of these balancing areas are much larger than others. The PJM grid, serving Pennsylvania, New Jersey, and Maryland, for example, is more than twice as large as Texas' ERCOT, in a state that produces and consumes the most electricity in the US.

Despite these limitations, it's possible to get hourly figures on how much electricity was generated, what was used to produce it, and whether it was used locally or exported to another balancing area. Information on the generating sources allowed the researchers to attach an emissions figure to each unit of electricity produced. Coal, for example, produces double the emissions of natural gas, which in turn produces more than an order of magnitude more carbon dioxide than the manufacturing of solar, wind, or hydro facilities. These figures were turned into what the authors call "embodied emissions" that can be traced to where they're eventually used.

Similar figures were also generated for sulfur dioxide and nitrogen oxides. Released by the burning of fossil fuels, these can both influence the global climate and produce local health problems.

Huge variation
The results were striking. "The consumption-based carbon intensity of electricity varies by almost an order of magnitude across the different regions in the US electricity system," the authors conclude. The low is the Bonneville Power grid region, which is largely supplied by hydropower; it has typical emissions below 100kg of carbon dioxide per megawatt-hour. The highest emissions come in the Ohio Valley Electric region, where emissions clear 900kg/MW-hr. Only three regional grids match the overall grid emissions intensity, although that includes the very large PJM (where capacity auction payouts recently fell), ERCOT, and Southern Co balancing areas.

Most of the low-emissions power that's exported comes from the Pacific Northwest's abundant hydropower, while the Rocky Mountains area exports electricity with the highest associated emissions. That leads to some striking asymmetries. Local generation in the hydro-rich Idaho Power Company has embodied emissions of only 71kg/MW-hr, while its imports, coming primarily from Rocky Mountain states, have a carbon content of 625kg/MW-hr.

The reliance on hydropower also makes the asymmetry seasonal. Local generation is highest in the spring as snow melts, but imports become a larger source outside this time of year. As solar and wind can also have pronounced seasonal shifts, similar changes will likely be seen as these become larger contributors to many of these regional grids. Similar things occur daily, as both demand and solar production (and, to a lesser extent, wind) have distinct daily profiles.

The Golden State
California's CISO provides another instructive case. Imports represent less than 30% of its total electric use in 2016, yet California electricity imports provided 40% of its embodied emissions. Some of these, however, come internally from California, provided by the Los Angeles Department of Water and Power. The state itself, however, has only had limited tracking of imported emissions, lumping many of its sources as "other," and has been exporting its energy policies to Western states in ways that shape regional markets.

Overall, the 2016 inventory provides a narrow picture of the US grid, as plenty of trends are rapidly changing our country's emissions profile, including the rise of renewables and the widespread adoption of efficiency measures and other utility trends in 2017 that continue to evolve. The method developed here can, however, allow for annual updates, providing us with a much better picture of trends. That could be quite valuable to track things like how the rapid rise in solar power is altering the daily production of clean power.

More significantly, it provides a basis for more informed policymaking. States that wish to promote low-emissions power can use the information here to either alter the source of their imports or to encourage the sites where they're produced to adopt more renewable power. And those states that are exporting electricity produced primarily through fossil fuels could ensure that the locations where the power is used pay a price that includes the health costs of its production.
