Utilities team up to build transmission lines

Rooftop solar grids transform urban infrastructure with distributed generation, photovoltaic panels, smart grid integration and energy storage, cutting greenhouse gas emissions, lowering utility costs, enabling net metering and community solar for low-carbon energy systems.

Key Points

Rooftop solar grids are PV systems on buildings that generate power, cut emissions, and enable smart grid integration.

✅ Lowers utility bills via net metering and demand offset

✅ Reduces greenhouse gases and urban air pollution

✅ Enables resiliency with storage, smart inverters, and microgrids

As urban areas expand and the climate crisis intensifies, cities are seeking innovative ways to integrate renewable energy sources into their infrastructure. One such solution gaining traction is the installation of rooftop solar grids. A recent CBC News article highlights the significant impact of these solar systems on urban environments, showcasing their benefits and the challenges they present.

Harnessing Unused Space for Sustainable Energy

Rooftop solar panels are revolutionizing how cities approach energy consumption and environmental sustainability. By utilizing the often-overlooked space on rooftops, these systems provide a practical solution for generating renewable energy in densely populated areas. The CBC article emphasizes that this approach not only makes efficient use of available space but also contributes to reducing a city's reliance on non-renewable energy sources.

The ability to generate clean energy directly from buildings helps decrease greenhouse gas emissions and, as scientists work to improve solar and wind power, promotes a shift towards a more sustainable energy model. Solar panels absorb sunlight and convert it into electricity, reducing the need for fossil fuels and lowering overall carbon footprints. This transition is crucial as cities grapple with rising temperatures and air pollution.

Economic and Environmental Advantages

The economic benefits of rooftop solar grids are considerable. For homeowners and businesses, installing solar panels can lead to substantial savings on electricity bills. The initial investment in solar technology is often balanced by long-term energy savings and financial incentives, such as tax credits or rebates, and evidence that solar is cheaper than grid electricity in Chinese cities further illustrates the trend toward affordability. According to the CBC report, these financial benefits make solar energy a compelling option for many urban residents and enterprises.

Environmentally, the advantages are equally compelling. Solar energy is a renewable and clean resource, and increasing the number of rooftop solar installations can play a pivotal role in meeting local and national renewable energy targets, as illustrated when New York met its solar goals early in a recent milestone. The reduction in greenhouse gas emissions from fossil fuel energy sources directly contributes to mitigating climate change and improving air quality.

Challenges in Widespread Adoption

Despite the clear benefits, the adoption of rooftop solar grids is not without its challenges. One of the primary hurdles is the upfront cost of installation. While prices for solar panels have decreased over time, the initial financial outlay remains a barrier for some property owners, and regions like Alberta have faced solar expansion challenges that highlight these constraints. Additionally, the effectiveness of solar panels can vary based on factors such as geographic location, roof orientation, and local weather patterns.

The CBC article also highlights the importance of supportive infrastructure and policies for the success of rooftop solar grids. Cities need to invest in modernizing their energy grids to accommodate the influx of solar-generated electricity, and, in the U.S., record clean energy purchases by Southeast cities have signaled growing institutional demand. Furthermore, policies and regulations must support solar adoption, including issues related to net metering, which allows solar panel owners to sell excess energy back to the grid.

Innovative Solutions and Future Prospects

The future of rooftop solar grids looks promising, thanks to ongoing technological advancements. Innovations in photovoltaic cells and energy storage solutions are expected to enhance the efficiency and affordability of solar systems. The development of smart grid technology and advanced energy management systems, including peer-to-peer energy sharing, will also play a critical role in integrating solar power into urban infrastructures.

The CBC report also mentions the rise of community solar projects as a significant development. These projects allow multiple households or businesses to share a single solar installation, making solar energy more accessible to those who may not have suitable rooftops for solar panels. This model expands the reach of solar technology and fosters greater community engagement in renewable energy initiatives.

Conclusion

Rooftop solar grids are emerging as a key element in the transition to sustainable urban energy systems. By leveraging unused rooftop space, cities can harness clean, renewable energy, reduce greenhouse gas emissions, and, as developers learn that more energy sources make better projects, achieve long-term economic savings. While there are challenges to overcome, such as initial costs and regulatory hurdles, the benefits of rooftop solar grids make them a crucial component of the future energy landscape. As technology advances and policies evolve, rooftop solar grids will play an increasingly vital role in shaping greener, more resilient urban environments.

Ontario CEAP Program provides one-time electricity bill relief for residential consumers via local utilities, supports low-income households, aligns with COVID-19 recovery rates, and complements time-of-use pricing options and the winter disconnection ban.

Key Points

A one-time electricity bill credit for eligible Ontario households affected by COVID-19, available via local utilities.

✅ Apply through your local distribution company or utility

✅ One-time credit for overdue electricity bills from COVID-19

✅ Complements TOU options, OER, and winter disconnection ban

Applications for the CEAP program for Ontario residential consumers has opened. Residential customers across the province can now apply for funding through their local distribution company/utility.

On June 1st, our government announced a suite of initiatives to support Ontario’s electricity consumers amid changes for electricity consumers during the pandemic, including a $9 million investment to support low-income Ontarians through the COVID-19 Energy Assistance Program (CEAP). CEAP will provide a one-time payment to Ontarians who are struggling to pay down overdue electricity bills incurred during the COVID-19 outbreak.

These initiatives include:

• $9 million for the COVID-19 Energy Assistance Program (CEAP) to support consumers struggling to pay their energy bills during the pandemic. CEAP will provide one-time payments to consumers to help pay down any electricity bill debt incurred over the COVID19 period. Applications will be available through local utilities in the upcoming months;
• $8 million for the COVID-19 Energy Assistance Program for Small Business (CEAP-SB) to provide support to businesses struggling with bill payments as a result of the outbreak; and
• An extension of the Ontario Energy Board’s winter disconnection ban until July 31, 2020 to ensure no one is disconnected from their natural gas or electricity service during these uncertain times.

More information about applications for the CEAP for Small Business will be coming later this summer, as electricity rates are about to change across Ontario for many customers.

In addition, the government recently announced that it will continue the suspension of time-of-use (TOU) electricity rates and, starting on June 1, 2020, customers will be billed based on a new fixed COVID-19 hydro rate of 12.8 cents per kilowatt hour. The COVID-19 Recovery Rate, which some warned in analysis could lead to higher hydro bills will be in place until October 31, 2020.

Later in the pandemic, Ontario set electricity rates at the off-peak price until February 7 to provide additional relief.

“Starting November 1, 2020, our government has announced Ontario electricity consumers will have the option to choose between time-of-use and tiered electricity pricing plan, following the Ontario Energy Board’s new rate plan prices and support thresholds announcement. We are proud to soon offer Ontarians the ability to choose an electricity plan that best suits for their lifestyle,” said Jim McDonell, MPP for Stormont–Dundas–South Glengarry.

The government will continue to subsidize electricity bills by 31.8 per cent through the Ontario Electricity Rebate.

The government is providing approximately $5.6 billion in 2020-21 as part of its existing electricity cost relief programs and conservation initiatives such as the Peak Perks program to help ensure more affordable electricity bills for eligible residential, farm and small business consumers.

NB Power Smart Meters will replace aging analog meters, boosting billing accuracy, reducing leakage, and modernizing distribution as the EUB considers a $92 million rollout of 360,000 advanced meters for residential and commercial customers.

Key Points

NB Power Smart Meters replace analog meters, improving billing accuracy and reducing leakage in the electricity network.

✅ EUB reviewing $92M plan for 360,000 advanced meters

✅ Replaces 98,000 analog units; curbs unbilled kWh

✅ Improves billing accuracy and reduces system leakage

Home and business owners with old power meters in New Brunswick have been getting the equivalent of up to 10 days worth of electricity a year or more for free, a multi million dollar perk that will end quickly if the Energy and Utilities Board approves the adoption of smart meters, a move that in other provinces has prompted refusal fees for some holdouts.

Last week the EUB began deliberations over whether to allow NB Power to purchase and install 360,000 new generation smart meters for its residential and commercial customers as part of a $92 million upgrade of its distribution system, even as regulators elsewhere approve major rate changes that affect customer bills.

If approved, that will spell the end to about 98,000 aging electromagnetic or analog meters still used by about one quarter of NB Power customers.  Those are the kind with a horizontal spinning silver disc and clock-face style dials that record consumption 

NB Power lawyer John Furey told the energy and utilities board last week that the utility suspects it loses several million dollars a year to electricity consumed by customers that is not properly recorded by their old meters. It was a central issue in Furey's argument for smart meters amid broader debates over industrial subsidies and debt. (Roger Cosman/CBC)
The analog units, some more than 50 years old and installed back when the late Louis Robichaud and Richard Hatfield were premiers in the 1960's and 1970's - are suspected of doling out millions of kilowatt hours of free power to customers by failing to register all of the current that moves through them.   

"Over time, analog meters slow down and they register lower consumption of electricity than is actually occurring," said NB Power lawyer John Furey last week about the widespread freeloading of power in New Brunswick caused by the old meters.

3 per cent missed
A 2010 report by the independent non-profit Electric Power Research Institute in Palo Alto, California and entered into evidence during NB Power's smart meter hearing said old spinning disc meters generally degrade over time and after 20 years typically fail to register nearly 3 per cent of the power that flows through them.

The average age of analog meters in New Brunswick is much older than that - 31 years - and more than 11,000 of the units are over the age of 40.

"Worn gears, corrosion, moisture, dust, and insects can all cause drag and result in an electromagnetic meter that does not capture the full consumption of the premises," said the report.

The sudden correction to full accounting and billing could naturally surprise these homeowners and even trigger consumer backlash in some cases

- Electric Power Research Institute report
About 94,000 NB residential customers and 3,900 commercial customers have an old meter, according to NB Power records. The group would receive about 40 million kilowatt hours of electricity for free this year  ($5.1 million worth including HST)  if the average unit failed to register 2 percent of the electricity flowing through it, while elsewhere some customers are receiving lump-sum credits on electricity bills.  

That is about $41 in free power for the average residential customer and $322 for the average business.

But, according to the research, there would also be hundreds of customers with meters that have slowed considerably more than the average with 0.3 percent - or close to 300 in NB Power's case -  not counting between 10 and 20 percent of the electricity customers are using. 

NB Power senior Vice President Lori Clark told the EUB stopping the freeloading of power in New Brunswick caused by older meters is in everyone's interest. (Roger Cosman/CBC)
That's potentially $400 in free electricity in a year for a residential customer with average consumption.

"While the average meter might be only slightly slow a few could be significantly so," said the report.

"The sudden correction to full accounting and billing could naturally surprise these homeowners and result in questioning of a new meter, as seen in a shocking $666 bill reported by a Nova Scotia senior." 

The report made the point analog meters can also run fast but called that "less common" meaning that if the EUB approves smart meters, tens of thousands of customers who lose an old meter to a new accurate model will experience higher bills.

'Leakage' reduction
NB Power acknowledges it does not know precisely how much power its older meters give away but said whether it is a little or a lot, ending the freebies is to everyone's benefit. 

"It reduces our inefficiencies, reduces our leakage that we have in the system, so that we are  picking up those unbilled kilowatt hours," said NB Power senior vice president Lori Clark about ending the free power many customers unknowingly enjoy.

Smart meter critics change tone on NB Power's new business case
NB Power's smart meter plan gets major boost with critical endorsements
"Customers benefit from reduced inefficiencies in our system. They benefit from reduced leakage in our system and the fact that those kilowatt hours are being properly billed to the customers that have consumed the kilowatt hours."   

NB Power hopes to win approval of its plan to acquire smart meters by this spring to allow installation beginning in mid 2021, even as some utilities elsewhere have backed away from smart home network projects.

Alberta NDP Net-Zero Electricity Plan targets a 2035 clean grid, expands renewable energy, cuts emissions, creates jobs, and boosts economic diversification and rural connectivity, aligning Alberta with Canada's 2050 climate goals.

Key Points

A policy to achieve a net-zero electricity grid by 2035, advance renewable energy, cut emissions, and grow jobs.

✅ Net-zero electricity grid target set for 2035

✅ Scales renewable energy and emissions reductions

✅ Focus on jobs, rural connectivity, and diversification

Ahead of the NDP’s weekend convention, Alberta’s Opposition leader has committed to transforming the province’s energy sector and moving the province’s electricity grid to net-zero by 2035, despite debate over the federal 2035 net-zero electricity grid target in other provinces, should an orange crush wash over Alberta in the next election.

NDP Leader Rachel Notley said they would achieve this as part of the path towards Canada’s 2050 net-zero emissions goal, aligning with broader clean grids trends, which will help preserve and create jobs in the province.

“I think it’s an important goal. It’s a way of framing the work that we’re going to do within our energy industry and our energy sector, including how Alberta produces and pays for electricity going forward,” said Notley. “We know the world is moving toward different objectives and we still have the ability to lead on that front, but we need to lay down the markers early and focus on reaching those goals.”

Premier Jason Kenney has previously called the 2050 target “aspirational,” and, as the electricity sector faces profound change in Alberta, Notley said, once the work begins, it’s likely they would meet the objective earlier than proposed to reduce greenhouse gas emissions that contribute to global warming.

This is just one key issue that will be addressed at the party’s online convention, which is the first since the NDP’s defeat by the UCP in the last provincial election. Notley said other key issues will address economic diversification, economic recovery, job creation and social issues, as Alberta’s electricity market is headed for a reshuffle too. The focus, as she puts it, is “jobs, jobs, jobs.”

Attendees will also debate more than 140 policy resolutions over the weekend, including the development of a safe supply drug policy, banning coal mining in the Rocky Mountains and providing paid sick leave for workers.

Outside the formal agenda, debate over electricity market competition continues in Alberta as stakeholders weigh options.

Notley said an area of growing focus for the NDP will be rural Alberta, which is typically a conservative stronghold. One panel presentation during the convention will focus on connecting and building relationships with rural Albertans and growing the NDP profile in those areas.

“We think that we have a lot to offer rural Alberta and that, quite frankly, the UCP and (Kenney), in particular, have profoundly taken rural Alberta for granted,” she said. “Because of that, we think with a renewed energy amongst our membership to go out to parts of the province where we haven’t been previously as active, and talk about what they have been subjected to in the last two years, that we have huge opportunities there.”

Delegates will be asked to support a call for high-speed internet coverage across Alberta, which would remove barriers to access in rural Alberta and Indigenous communities, said the convention guidebook.

The convention comes as the NDP has a wide lead on the UCP, according to the latest polls. A Leger online survey of 1,001 Albertans conducted between March 5 to 8 found 40 per cent of respondents support the NDP, compared to just 20 per cent for the UCP.

Notley said it’s “encouraging” to see, but they aren’t taking anything for granted.

“I’ve always believed that Alberta Democrats have to work twice as hard as anybody else in the political spectrum, or the political arena,” she said. “So what we’re going to do is continue to do exactly what we have been, not only being a strong and I would argue fearless Opposition, but also trying to match every oppositional position with something that is propositional — offering Albertans a different vision, including an Alberta path to clean electricity where possible.”

Canada Electrification Costs: report estimates $580B-$1.4T to scale renewable energy, wind, solar, and storage capacity to 2050, shifting from natural gas toward net-zero emissions and raising average household energy spending by $1,300-$3,200 annually.

Key Points

Projected national expense to expand renewables and electrify energy systems by 2050, impacting household energy bills.

✅ $580B-$1.4T forecast for 2020-2050 energy transition

✅ 278-422 GW wind, solar, storage capacity by 2050

✅ Household costs up $1,300-$3,200 per year on average

The Canadian Gas Association says building renewable electricity capacity to replace just half of Canada's current fossil fuel-generated energy, a shift with significant policy implications for grids across provinces, could increase national costs by as much as $1.4 trillion over the next 30 years.

In a report, it contends, echoing an IEA report on net-zero, that growing electricity's contribution to Canada's energy mix from its current 19 per cent to about 60 per cent, a step critical to meeting climate pledges that policymakers emphasize, will require an expansion from 141 gigawatts today to between 278 and 422 GW of renewable wind, solar and storage capacity by 2050.

It says that will increase national energy costs by between $580 billion and $1.4 trillion between 2020 and 2050, a projection consistent with recent reports of higher electricity prices in Alberta amid policy shifts, translating into an average increase in Canadian household spending of $1,300 to $3,200 per year.

The study, prepared by consulting firm ICF for the association, assumes electrification begins in 2020 and is applied in all feasible applications by 2050, with investments in the electricity system, guided by the implications of decarbonizing the grid for reliability and cost, proceeding as existing natural gas and electric end use equipment reaches normal end of life.

Association CEO Tim Egan says the numbers are "pretty daunting" and support the integration of natural gas with electric, amid Canada's race to net-zero commitments, instead of using an electric-only option as the most cost-efficient way for Canada to reach environmental policy goals.

But Keith Stewart, senior energy strategist with Greenpeace Canada, says scientists are calling for the world to get to net-zero emissions by 2050, and Canada's net-zero by 2050 target underscores that urgency to avoid "catastrophic" levels of warming, so investing in natural gas infrastructure to then shut it down seems a "very expensive option."
