Ultra-Low Overnight Price Plan delivers flexible electricity pricing from Hydro One and the Ontario Energy Board, with TOU, tiered options, off-peak EV charging savings, balanced billing, and an online calculator to optimize bills.

Key Points

An Ontario pricing option with ultra-low night rates, helping Hydro One customers save by shifting usage to off-peak.

✅ Four periods with ultra-low overnight rate for EV charging

✅ Compare TOU vs tiered with Hydro One's online calculator

✅ Balanced billing and due date choice support budget control

Hydro One has announced that customers have even more choice and flexibility when it comes to how they are billed for electricity with the company's launch of the Ontario Energy Board's new Ultra-Low Overnight Electricity Price Plan for customers. A new survey of Ontario customers, conducted by Innovative Research Group, shows that 74 per cent of Ontarians find having choice between electricity pricing plans useful.

"As their trusted energy advisor, we want our customers to know we have the insights and tools to help them make the right choice when it comes to their electricity plans," said Teri French, Executive Vice President, Safety, Operations and Customer Experience. "We know that choice and flexibility are important to our customers, and we are proud to now offer them a third option so they can select the plan that best fits their lifestyle."

The same survey revealed that fewer than half of Ontarians are familiar with either tiered or the new ultra-low overnight price plans. To better support its customers Hydro One is providing an online calculator to help them choose which pricing plan best suits their lifestyle. The company also offers additional flexibility and assistance in managing household budgets by providing customers with the ability to choose their billing due date and flatten usage spikes from temperature fluctuations through balanced billing.

During the pandemic, Ontario introduced electricity relief to support families, small businesses and farms, complementing these customer options.

"By offering families and small businesses more choice, we are putting them back in control of their energy bills," said Todd Smith, Minister of Energy. "Starting today Hydro One customers have a new option - the Ultra-Low Electricity Price Plan - which could help them save money each year, while making our province's grid more efficient."

Electricity price plan options

• New Ultra-Low Overnight price plan (ULO): Designed for customers who use more electricity at night, such as those who charge their electric vehicle, this new price plan can help customers keep costs down and take control of their electricity bill by shifting usage to the ultra-low overnight price period and related off-peak electricity rates when province-wide electricity demand is lower.
• This plan has four price periods that are the same in the summer as they are in the winter and includes an ultra-low overnight rate.
• Time-of-Use price plan (TOU): TOU provides customers with more control over their electricity bill by adjusting their usage habits with time-of-use rates used in other jurisdictions as well.
• In this plan, electricity prices change throughout each weekday, when demand is on-peak, and peak hydro rates can affect overall costs.
• Tiered price plan (RPP): Tiered pricing provides customers with the flexibility to use electricity at any time of day at the same low price up until the threshold is exceeded during the month, after that usage is charged at a higher price.
• For residential customers, the winter period (November 1 – April 30) threshold is 1,000 kWh per month and the summer period (May 1 – October 31) threshold is 600 kWh per month. 
• For small business customers, the threshold is 750 kWh throughout the year, while broader stable electricity pricing supports industrial and commercial companies.

New York Renewable Energy Contracts secure 23 projects totaling 2.3 GW, spanning offshore wind, solar, and battery storage under CLCPA goals, advancing 70% by 2030, a carbon-free 2040 grid, grid reliability, and green jobs.

Key Points

State agreements securing 23 wind, solar, and storage projects (2.3 GW) to meet CLCPA clean power targets.

✅ 2.3 GW across 23 wind, solar, and storage projects statewide

✅ Supports 70% renewables by 2030; carbon-free grid by 2040

✅ Drives emissions cuts, grid reliability, and green jobs

In a significant milestone for the state’s clean energy ambitions, New York has finalized contracts with 23 renewable energy projects, as part of large-scale energy projects underway in New York, totaling a combined capacity of 2.3 gigawatts (GW). This move is part of the state’s ongoing efforts to accelerate its transition to renewable energy, reduce carbon emissions, and meet the ambitious targets set under the Climate Leadership and Community Protection Act (CLCPA), which aims to achieve a carbon-free electricity grid by 2040.

A Strong Commitment to Renewable Energy

The 23 projects secured under these contracts represent a diverse range of renewable energy sources, including wind, solar, and battery storage. Together, these projects are expected to contribute significantly to New York’s energy grid, generating enough clean electricity to power millions of homes. The deal is a key component of New York’s broader strategy to achieve a 70% renewable energy share in the state’s electricity mix by 2030 and to reduce greenhouse gas emissions by 85% by 2050.

Governor Kathy Hochul celebrated the agreements as a major step forward in the state’s commitment to combating climate change while creating green jobs and economic opportunities. “New York is leading the nation in its clean energy goals, and these projects will help us meet our bold climate targets while delivering reliable and affordable energy to New Yorkers,” Hochul said in a statement.

The Details of the Contracts

The 23 projects span across various regions of the state, with an emphasis on areas that are well-suited for renewable energy development, such as upstate New York, which boasts vast open spaces ideal for large-scale solar and wind installations and the state is investigating sites for offshore wind projects along the coast. The contracts finalized by the state will ensure a steady supply of clean power from these renewable sources, helping to stabilize the grid and reduce reliance on fossil fuels.

A significant portion of the new renewable capacity will come from offshore wind projects, which have become a cornerstone of New York’s renewable energy strategy. Offshore wind has the potential to provide large amounts of electricity, and the state recently greenlighted the country's biggest offshore wind farm to date, taking advantage of the state's proximity to the Atlantic Ocean. Several of the contracts finalized include offshore wind farm projects, which are expected to be operational within the next few years.

In addition to wind energy, solar power continues to be a critical component of the state’s renewable energy strategy. The state has already made substantial investments in solar energy, having achieved solar energy goals ahead of schedule recently, and these new contracts will further expand the state’s solar capacity. The inclusion of battery storage projects is another important element, as energy storage solutions are vital to ensuring that renewable energy can be effectively utilized, even when the sun isn’t shining or the wind isn’t blowing.

Economic and Job Creation Benefits

The finalization of these 23 contracts will not only bring significant environmental benefits but also create thousands of jobs in the renewable energy sector. Construction, maintenance, and operational jobs will be generated throughout the life of the projects, benefiting communities across the state, including areas near Long Island's South Shore wind proposals that stand to gain from new investment. The investment in renewable energy is expected to support New York’s recovery from the economic impacts of the COVID-19 pandemic, contributing to the state’s clean energy economy and providing long-term economic stability.

The state's focus on clean energy also provides opportunities for local businesses, highlighted by the first Clean Energy Community designation in the state, as many of these projects will require services and materials from within New York State. Additionally, Governor Hochul’s administration has made efforts to ensure that disadvantaged communities and workers from underrepresented backgrounds will have access to job training and employment opportunities within the renewable energy sector.

The Path Forward: A Clean Energy Future

New York’s aggressive move toward renewable energy is indicative of the state’s commitment to addressing climate change and leading the nation in clean energy innovation. By locking in contracts for these renewable energy projects, the state is not only securing a cleaner future but also ensuring that the transition is fair and just for all communities, particularly those that have been historically impacted by pollution and environmental degradation.

While the finalized contracts mark a major achievement, the state’s work is far from over. The completion of these 23 projects is just one piece of the puzzle in New York’s broader strategy to decarbonize its energy system. To meet its ambitious targets under the CLCPA, New York will need to continue investing in renewable energy, energy storage, grid modernization, and energy efficiency programs.

As New York moves forward with its clean energy transition, and as BOEM receives wind power lease requests in the Northeast, the state will likely continue to explore new technologies and innovative solutions to meet the growing demand for renewable energy. The success of the 23 finalized contracts serves as a reminder of the state’s leadership in the clean energy space and its ongoing efforts to create a sustainable, low-carbon future for all New Yorkers.

New York’s decision to finalize contracts with 23 renewable energy projects totaling 2.3 gigawatts represents a bold step toward meeting the state’s clean energy and climate goals. These projects, which include a mix of wind, solar, and energy storage, will contribute significantly to reducing the state’s reliance on fossil fuels and lowering greenhouse gas emissions. With the additional benefits of job creation and economic growth, this move positions New York as a leader in the nation’s transition to renewable energy and a sustainable future.

Manitoba Hydro Integrated Resource Plan outlines electrification-driven demand growth, clean electricity needs, wind generation, energy efficiency, hydropower strengths, and net-zero policy impacts, guiding investments to expand capacity and decarbonize Manitoba's grid.

Key Points

Manitoba Hydro IRP forecasting 2.5x demand, clean power needs, and capacity additions via wind and energy efficiency.

✅ Projects electricity demand could more than double within 20 years.

✅ Leverages 97% hydro supply; adds wind generation and efficiency.

✅ Positions for net-zero, electrification, and new capacity by the 2030s.

Electrical demand in Manitoba could more than double in the next 20 years, a trend echoed by BC Hydro's call for power in response to electrification, according to a new report from Manitoba Hydro.

On Tuesday, the Crown corporation released its first-ever Integrated Resource Plan (IRP), which not only predicts a significant increase in electrical demand, but also that new sources of energy, and a potential need for new power generation, could be needed in the next decade.

“Right now, what [our customers] are telling us, with the climate change objectives, with federal policy, provincial policies, is they see using electricity much more in the future than they do today,” said president and CEO of Manitoba Hydro Jay Grewal.

“And our current, where we’re at now, our customers have told us through all this consultation and engagement over the last two years, they’re going to want and need more than 2.5 times the electricity than we have in the province today.”

The IRP indicates that the move towards low or no-carbon energy sources will accelerate the need for clean electricity, which will require significant investments, including new turbine investments to expand capacity. Some of the clean energy measures Hydro is looking at for the future include wind generation and energy efficiency.

The report also found that Manitoba is in a good position as it prepares for the future due to its hydroelectric system, which delivers around 97 per cent of the yearly electricity. However, the province’s existing supply is limited, and vulnerable to Western Canada drought impacts on hydropower, so other electrical energy sources will be needed.

“Something Manitobans may not realize is, we are in such a privileged province, because 97 per cent of the electricity produced in Manitoba today is clean energy and net zero,” Grewal said.

Manitoba also supplies power to neighbouring utilities, with a SaskPower purchase agreement to buy more electricity under an expanded deal.

The IRP is the result of a two-year development process that involved multiple rounds of engagement with customers and other interested parties. The IRP is not a development plan, but it arrives as Hydro warns it can't service new energy-intensive customers under current capacity, and it outlines how Manitoba Hydro will monitor, prepare and respond to the changes in the energy landscape.

“We spoke with over 15,000 of our customers, whether they’re residential, commercial, industrial, industry associations, regulators, government – across the board, we talked with our customers,” said Grewal.

“And what we did was through this work, we understood what our customers are anticipating using electricity for going forward.

Churchill Falls NL-Quebec Agreement boosts hydropower revenues, revises power purchase pricing, expands transmission lines, and integrates Indigenous rights, enabling renewable energy growth, domestic supply, exports, and interprovincial collaboration on infrastructure and utility modernization.

Key Points

A renegotiated hydropower deal reallocating power and advancing projects with Indigenous benefits in NL and Quebec.

✅ Raises Hydro-Quebec price for Churchill Falls electricity

✅ Increases NL power share for domestic use and exports

✅ Commits joint projects and Indigenous participation safeguards

St. John's, Newfoundland and Labrador - In a historic development, Newfoundland and Labrador (NL) and Quebec have reached a tentative agreement over the controversial Churchill Falls hydroelectric project, amid Quebec's electricity ambitions and longstanding regional sensitivities, potentially unlocking hundreds of billions of dollars for the Atlantic province. The deal, announced jointly by Premier Andrew Furey and Quebec Premier François Legault, aims to rectify the decades-long imbalance in the original 1969 contract, which saw NL receive significantly less revenue than Quebec for the province's vast hydropower resources.

The core of the new agreement involves a substantial increase in the price that Hydro-Québec pays for electricity generated at Churchill Falls. This price hike, retroactive to January 1, 2025, is expected to generate billions in additional revenue for NL over the next several decades. The deal also includes provisions for:

• Increased power allocation for NL: The province will gain a larger share of the electricity generated at Churchill Falls, allowing for increased domestic consumption and potential export opportunities through the sale and trade of power across regional markets.
• Joint infrastructure development: Both provinces will collaborate on new energy projects, in line with Hydro-Québec's $185-billion plan to reduce fossil fuel reliance, including potential expansions to the Churchill Falls generating station and the development of new transmission lines.
• Indigenous involvement: The agreement acknowledges the importance of Indigenous rights and seeks to ensure that Indigenous communities in both provinces benefit from the project.

This landmark deal represents a significant victory for NL, which has long argued that the original 1969 contract was grossly unfair. The province has been seeking to renegotiate the terms of the agreement for decades, citing the low price paid for electricity and the significant economic benefits that have accrued to Quebec.

Key Implications:

• Economic Transformation: The influx of revenue from the new Churchill Falls agreement has the potential to significantly transform the economy of NL, though the legacy of Muskrat Falls costs tempers expectations before plans are finalized. The province can invest in critical infrastructure projects, such as healthcare, education, and transportation, as well as support economic diversification initiatives.
• Energy Independence: The increased access to electricity will enhance NL's energy security and reduce its reliance on fossil fuels. This shift towards renewable energy aligns with the province's climate change goals, and in the context of Quebec's no-nuclear stance could attract new investment in sustainable industries.
• Interprovincial Relations: The successful negotiation of this complex agreement demonstrates the potential for constructive collaboration between provinces on major infrastructure projects, as seen in recent NB Power-Hydro-Québec agreements to import more electricity. It sets a precedent for future interprovincial partnerships on issues of shared interest.

Challenges and Considerations:

• Implementation: The successful implementation of the agreement will require careful planning and coordination between the two provinces.
• Environmental Impact: The expansion of hydroelectric generation at Churchill Falls must be carefully assessed for its potential environmental impacts, including the effects on local ecosystems and Indigenous communities.
• Public Consultation: It is crucial that the governments of NL and Quebec engage in meaningful public consultation throughout the implementation process to ensure that the benefits of the agreement are shared equitably across both provinces.

The Churchill Falls agreement marks a turning point in the history of energy development in Canada. It demonstrates the potential for provinces to work together to achieve mutually beneficial outcomes, even as Nova Scotia shifts toward wind and solar after stepping back from the Atlantic Loop, while also addressing historical inequities and ensuring a more equitable distribution of the benefits of natural resources.

PG&E Public Safety Power Shutoff reduces wildfire risk during extreme winds, triggering de-energization across the North Bay and Sierra Foothills under red flag warnings, with safety inspections and staged restoration to improve grid resilience.

Key Points

A utility protocol to de-energize lines during extreme fire weather, reducing ignition risks and improving grid safety.

✅ Triggered by red flag warnings, humidity, wind, terrain

✅ Temporary de-energization of transmission and distribution lines

✅ Inspections precede phased restoration to minimize wildfire risk

PG&E purposefully shut off electricity to nearly 60,000 Northern California customers Sunday night, aiming to mitigate wildfire risks from power lines during extreme winds.

Pacific Gas and Electric planned to restore power to 70 percent of affected customers in the North Bay and Sierra Foothills late Monday night. As crews inspect lines for safety by helicopter, vehicles and on foot, the remainder will have power sometime Tuesday.

While it was the first time the company shut off power for public safety, PG&E announced its criteria and procedures for such an event in June, said spokesperson Paul Doherty. After wildfires devastated Northern California's wine country last October, he added, PG&E developed its community wildfire safety program division to make power grids and communities more resilient, and prepares for winter storm season through enhanced local response. 

Two sagging PG&E power lines caused one of those wildfires during heavy winds, killing four people and injuring a firefighter, the California Department of Forestry and Fire Protection determined earlier this month. Trees or tree branches hitting PG&E power lines started another four wildfires in October 2017. Altogether, the power company has been blamed for igniting 13 wildfires last year.

"We're adapting our electric system our operating practices to improve safety and reliability," Doherty said of the safety program. "That's really the bottom line for us."

Turning off power to so many customers was a "last resort given the extreme fire danger conditions these communities are experiencing," Pat Hogan, senior vice president of electric operations, said in a statement. Conditions that led the company to shut off power included the National Weather Service's red flag fire warnings, humidity levels, sustained winds, temperature, dry fuel and local terrain, Doherty said, amid possible rolling blackouts during grid strain.

The company de-energized more than 78 miles of transmission lines and more than 2,150 miles of distribution power lines Sunday night. Many schools in the area were closed Monday because of the planned power outage, highlighting unequal access to electricity across communities.

Late Saturday and early Sunday, PG&E warned 97,000 customers in 12 counties that the shut off might go into effect. Through automated calls, texts and emails, the company encouraged customers to have drinking water, canned food, flashlights, prescriptions and baby supplies on hand.

Power was also turned off in Southern California on Monday.

San Diego Gas & Electric turned off service to about 360 customers near Cleveland National Forest, where multiple fires have scorched large swaths of land in recent years.

SDG&E has pre-emptively shut off power to customers in the past, most recently in December when 14,000 customers went without power.

Southern California Edison, the primary electric provider across Southern California — including Los Angeles — has a similar power shutoff program. As of Monday night, SCE had yet to turn off power in any of its service areas, a spokesperson told USA TODAY.

Nighttime thermoradiative power converts outgoing infrared radiation into electricity using semiconductor photodiodes, leveraging negative illumination and sky cooling to harvest renewable energy from Earth-to-space heat flow when solar panels rest, regardless of weather.

Key Points

Nighttime thermoradiative power converts Earth's outgoing infrared heat into electricity using semiconductor diodes.

✅ Uses negative illumination to tap Earth-to-space heat flow

✅ Infrared semiconductor photodiodes generate small nighttime current

✅ Theoretical output ~4 W/m^2; lab demo reached 64 nW/m^2

There's a stark contrast between the freezing temperatures of space and the relatively balmy atmosphere of Earth, and that contrast could help generate electricity, scientists say – and alongside concepts such as space-based solar power, utilizing the same optoelectronic physics used in solar panels. The obvious difference this would have compared with solar energy is that it would work during the night time, a potential source of renewable power that could keep on going round the clock and regardless of weather conditions.

Solar panels are basically large-scale photodiodes - devices made out of a semiconducting material that converts the photons (light particles) coming from the Sun into electricity by exciting electrons in a material such as silicon, while concepts like space solar beaming could complement them during adverse weather.

In this experiment, the photodiodes work 'backwards': as photons in the form of infrared radiation - also known as heat radiation - leave the system, a small amount of energy is produced, similar to how raindrop electricity harvesting taps ambient fluxes in other experiments.

This way, the experimental system takes advantage of what researchers call the "negative illumination effect" – that is, the flow of outgoing radiation as heat escapes from Earth back into space. The setup explained in the new study uses an infrared semiconductor facing into the sky to convert this flow into electrical current.

"The vastness of the Universe is a thermodynamic resource," says one of the researchers, Shanhui Fan from Stanford University in California.

"In terms of optoelectronic physics, there is really this very beautiful symmetry between harvesting incoming radiation and harvesting outgoing radiation."

It's an interesting follow-up to a research project Fan participated in last year: a solar panel that can capture sunlight while also allowing excess heat in the form of infrared radiation to escape into space.

In the new study, this "energy harvesting from the sky" process can produce a measurable amount of electricity, the researchers have shown – though for the time being it's a long way from being efficient enough to contribute to our power grids, but advances in peer-to-peer energy sharing could still make niche deployments valuable.

In the team's experiments they were able to produce 64 nanowatts per square metre (10.8 square feet) of power – only a trickle, but an amazing proof of concept nevertheless. In theory, the right materials and conditions could produce a million times more than that, and analyses of cheap abundant electricity show how rapidly such advances compound, reaching about 4 watts per square metre.

"The amount of power that we can generate with this experiment, at the moment, is far below what the theoretical limit is," says one of the team, Masashi Ono from Stanford.

When you consider today's solar panels are able to generate up to 100-200 watts per square metre, and in China solar is cheaper than grid power across every city, this is obviously a long way behind. Even in its earliest form, though, it could be helpful for keeping low-power devices and machines running at night: not every renewable energy device needs to power up a city.

Now that the researchers have proved this can work, the challenge is to improve the performance of the experimental device. If it continues to show promise, the same idea could be applied to capture energy from waste heat given off by machinery, and results in humidity-powered generation suggest ambient sources are plentiful.

"Such a demonstration of direct power generation of a diode facing the sky has not been previously reported," explain the researchers in their published paper.

"Our results point to a pathway for energy harvesting during the night time directly using the coldness of outer space."

The research has been published in Applied Physics Letters.
