Microgrid solar outage algorithms optimize renewable energy during blackouts using grid-forming inverters, islanding control, demand forecasting, and energy storage from batteries and EVs, improving reliability by up to 35% for resilient power sharing.

Key Points

Algorithms that island homes, forecast demand, and prioritize critical loads using storage and grid-forming inverters.

✅ Disconnects inverters to form resilient neighborhood microgrids

✅ Forecasts solar, wind, and demand; allocates energy fairly

✅ Uses EVs and batteries; boosts reliability by up to 35%

Some people who have solar panels on their roof are under the impression that they can use them to power their home in the case of an outage, but that simply is not the case. Homes do remain connected to the grid during outages, as U.S. power outage risks grow, but the devices tasked with managing solar panels are normally turned off due to safety concerns. This permanent grid connection essentially prevents homeowners from drawing on the power that their own renewable energy resources generate.

This could be about to change, however, thanks to the efforts of a team of University of California San Diego engineers who have come up with algorithms that would enable homes to share and use their power in outages by disconnecting solar inverters from the grid. Their algorithms work with the existing technology and would have the added benefit of boosting the system’s reliability by as much as 35 percent.

The genius of their work lies in the ability of the algorithm to prioritize the distribution of power from the renewable resources in outages. Their equation considers forecasts for wind and solar power generation to address clean energy intermittency challenges and the available energy storage, including batteries and electric vehicles. It combines this information with the projected energy usage of residents and the amount of energy the homes are able to produce. It can be programmed to prioritize in several different ways, the most vital of which is by favoring those who need power urgently, such as those using life support equipment. It could also prioritize those who are willing to pay extra or reward those who typically generate an energy surplus during normal operations.

Learning lessons from past outages

Lead author Abdulelah H. Habib said the engineers were inspired to find a way to use the renewable power in outages by the events of Hurricane Sandy. This storm affected more than eight million people on the nation’s East Coast, some of whom were left without power for as long as two weeks.

According to the researchers, most customers prefer sharing community-scale storage systems over having systems in each home because of the lower costs. One of the paper’s senior authors, Raymond de Callafon, said that homes that are connected together are not only more resilient in power outages but they also happen to be more resilient to price fluctuations.

Each home needs to be equipped with special circuit breakers that can be remotely controlled, while utilities would need to install some communications methods so the power systems within a particular residential cluster can communicate amongst themselves. They also need a “grid forming inverter” to help them connect to one another and manage excess solar on networks safely.

One stumbling block that will have to be overcome is the current regulations. Most states do not allow individual homeowners to sell power to other homeowners, so there would have to be some adjustments to make this a reality.

Solar power growing in popularity

Solar power’s popularity is currently on the rise, and reductions in cost as the technology improves are only expected to drive this growth even further. REC CEO Steve O’Neil told CNBC that the installation rates of solar double every two years, a trend that informs residential solar economics for homeowners even though just two percent of the planet’s electricity comes from converting sunlight to energy. This means there is plenty of room for expansion. The world’s current solar capacity is 305 gigawatts, compared to just 50 gigawatts in 2010.

In addition, he pointed out that the price of solar energy has dropped by 70 percent since the year 2010 and continues to fall; it costs around eight cents per kilowatt hour at the moment. Another factor that could boost adoption is storage improvements, driven by affordable solar batteries that expand capacity, which will allow solar energy to be used even on overcast days.

B.C. Hydro fast EV charging stations roll out 180 kW DC fast chargers, power sharing, and rural network expansion in Surrey, Manning Park, Mackenzie, and Tumbler Ridge to ease range anxiety across northern B.C.

Key Points

180 kW DC chargers with power sharing, expanding B.C.'s rural EV network to cut range anxiety and speed up recharging.

✅ 180 kW DC fast charging: ~180 km added in about 10 minutes

✅ Power sharing enables two vehicles to use one unit simultaneously

✅ Expands rural charging coverage to cut range anxiety for northern B.C.

B.C. Hydro has unveiled plans to install new charging stations it says can add as much as 180 kilometres worth of range to the average electric vehicle in 10 minutes.

The utility says the new 180-kilowatt units will be added to its network, expanding stations in southern B.C. as soon as this fall, with even more scheduled to arrive in 2024.

The first communities to get the new faster-charge stations are Surrey, Manning Park and, north of Prince George, Mackenzie and Tumbler Ridge, while the Lillooet fast-charging site is already operational.

B.C. Hydro president Chris O'Riley says both current and prospective electric vehicle owners have said they want improved coverage in more rural parts of the province in order to address range anxiety, as the utility has warned of a potential EV charging bottleneck if demand outpaces infrastructure.

"We are listening to feedback from our customers," he said.

The new stations will also be the first from B.C. Hydro to offer power sharing, which lets two different vehicles use the same unit to charge at the same time.

The adoption of electric vehicles in B.C. is much higher in southern urban areas than rural, northern ones, according to statistics from the provincial government made available in 2022, as the province leads the country in going electric according to recent reports.

The figures showed about one in every 45 people owns a zero-emission vehicle in the southwest regions of the province, but that number drops to one in 232 in the Kootenays, where the region makes electric cars a priority through local initiatives, and one in 414 in northern B.C.

The number of public charging stations closely corresponds to the number of zero-emission vehicles in various regions.

The Vancouver area has more than 500 fast-charging ports, according to ChargeHub, a website that tracks charging stations in North America. 

In contrast, the route from Prince George to Fort Nelson via Dawson Creek along Highway 97, part of the B.C. Electric Highway network connecting the region — a distance of more than 800 kilometres — has just three locations where a vehicle can be charged to 80 per cent power in an hour or less, creating challenges for people hoping to travel the route.

The disparity is also clear in a just-published analysis from the non-profit Community Energy Association, which acts as an advisory group to government associations. 

It found that while there is roughly one charging port every three square kilometres in Metro Vancouver, the number drops to one every 250 square kilometres in the Regional District of East Kootenay and one every 3,500 square kilometres in the Peace River Regional District, in the province's northeast.

"The more infrastructure we can get across the region ... the more the adoption of electric vehicles will increase," said the association's director of transportation initiatives, Danielle Weiss.

"We are excited to hear that B.C. Hydro is also viewing rural areas as a key focus for their new, enhanced charging technology."

B.C. Hydro says it currently has 153 charging units at 84 locations across the province with plans to add an additional 3,000 ports over the next 10 years, with provincial EV charger rebates supporting home and workplace installations as well.

Britain Wind Generation Record underscores onshore and offshore wind momentum, as National Grid ESO reported 20.91 GW, boosting zero-carbon electricity, renewables share, and grid stability amid milder weather, falling gas prices, and net zero goals.

Key Points

The Britain wind generation record is 20.91 GW, set on 30 Dec, driven by onshore and offshore turbines.

✅ Set on 30 Dec 2022 with peak output of 20.91 GW.

✅ Zero-carbon sources hit 87.2% of grid supply.

✅ Driven by onshore and offshore wind; ESO reported stability.

Britain has set a new record for wind generation as power from onshore and offshore turbines helped boost clean energy supplies late last year.

National Grid’s electricity system operator (ESO), which handles Great Britain’s grid operations, said that a new record for wind generation was set on 30 December, when 20.91 gigawatts (GW) were produced by turbines.

This represented the third time Britain’s fleet of wind turbines set new generation records in 2022. In May, National Grid had to ask some turbines in the west of Scotland to shut down, as the network was unable to store such a large amount of electricity when a then record 19.9GW of power was produced – enough to boil 3.5m kettles.

The ESO said a new record was also set for the share of electricity on the grid coming from zero-carbon sources – renewables and nuclear – which supplied 87.2% of total power. These sources have accounted for about 55% to 59% of power over the past couple of years.

The surge in wind generation represents a remarkable reversal in fortunes as a cold snap that enveloped Britain and Europe quickly turned to milder weather.

Power prices had soared as the freezing weather forced Britons to increase their heating use, pushing up demand for energy despite high bills.

The cold weather came with a period of low wind, reducing the production of Britain’s windfarms to close to zero.

Emergency coal-fired power units at Drax in North Yorkshire were put on standby but ultimately not used, while gas-fired generation accounted for nearly 60% of the UK’s power output at times.

However, milder weather in the UK and Europe in recent days has led to a reduction in demand from consumers and a fall in wholesale gas prices. It has also reduced the risk of power cuts this winter, which National Grid had warned could be a possibility.

Wind generation is increasingly leading the power mix in Britain and is seen as a crucial part of Britain’s move towards net zero. The prime minister, Rishi Sunak, is expected to overturn a moratorium on new onshore wind projects with a consultation on the matter due to run until March.

US Renewable Energy Cost Advantage signals cheaper utility-scale solar and onshore wind versus natural gas, with LCOE declines, tax credits, and climate policy cutting electricity costs for utilities and grids across the United States.

Key Points

Cheaper solar and wind than natural gas, driven by LCOE drops, tax credits, and policy, lowering US electricity costs.

✅ Utility-scale solar is about one-third cheaper than gas

✅ Onshore wind costs roughly 44 percent less than natural gas

✅ Policy and tax credits accelerate renewables and cut power prices

Natural gas’s dominance as power-plant fuel in the US is fading fast as the cost of electricity generated by US wind and solar projects tumbles and as wind and solar surpass coal in the generation mix, according to Guggenheim Securities.

Utility-scale solar is now about a third cheaper than gas-fired power, while onshore wind is about 44% less expensive, Guggenheim analysts led by Shahriar Pourreza said Monday in a note to clients, a dynamic consistent with falling wholesale power prices in several markets today. 

“Solar and wind now present a deflationary opportunity for electric supply costs,” the analysts said, which “supports the case for economic deployment of renewables across the US,” as the country moves toward 30% wind and solar and one-fourth of total generation in the near term.

Gas prices have surged amid a global supply crunch after Russia’s invasion of Ukraine, while tax-credit extensions and sweeping US climate legislation have brought down the cost of wind and solar, even as renewables surpassed coal in 2022 nationwide. Renewables-heavy utilities like NextEra Energy Inc. and Allete Inc. stand to benefit, and companies that can boost spending on wind and solar, as wind, solar and batteries dominate the 2023 pipeline, will also see faster growth, Guggenheim said.

Ontario EV Charger Streamlining accelerates public charging connections with OEB-led standardized forms, firm timelines, and utility coordination, leveraging Ontario’s clean electricity grid to expand reliable infrastructure across urban, rural, and northern communities.

Key Points

An OEB-led, provincewide procedure that standardizes EV charger connections and accelerates public charging.

✅ Standardized forms, data, and responsibilities across 58 utilities

✅ Firm timelines for studies, approvals, and grid connection upgrades

✅ Supports rural, northern, highway, and community charging expansion

The Ontario government is making it easier to build and connect new public electric vehicle (EV) chargers to the province’s world-class clean electricity grid. Starting May 27, 2024, all local utilities will follow a streamlined process for EV charging connections that will make it easier to set up new charging stations and, as network progress to date shows, support the adoption of electric vehicles in Ontario.

“As the number of EV owners in Ontario continues to grow, our government is making it easier to put shovels in the ground to build the critical infrastructure needed for drivers to charge their vehicles where and when they need to,” said Todd Smith, Minister of Energy. “This is just another step we are taking to reduce red tape, increase EV adoption, and use our clean electricity supply to support the electrification of Ontario’s transportation sector.”

Today, each of Ontario’s 58 local electricity utilities have different procedures for connecting new public EV charging stations, with different timelines, information requirements and responsibilities for customers.

In response to Minister Smith’s Letter of Direction, which called on the Ontario Energy Board (OEB) to take steps to facilitate the efficient integration of EV’s into the provincial electricity system, including vehicle-to-building charging applications, the OEB issued provincewide, streamlined procedures that all local utilities must follow for installing and connecting new EV charging infrastructure. This new procedure includes the implementation of standardized forms, timelines, and information requirements which will make it easier for EV charging providers to deploy chargers in all regions of the province.

“Our government is paving the way to an electric future by building the EV charging infrastructure drivers need, where they need it,” said Prabmeet Sarkaria, Minister of Transportation. “By increasing the accessibility of public EV charging stations across the province, including for rural and northern communities, we are providing more sustainable and convenient travel options for drivers.”

“Having attracted over $28 billion in automotive investments in the last three years, our province is a leading jurisdiction in the global production and development of EVs,” said Vic Fedeli, Minister of Economic Development, Job Creation and Trade. “By making it easier to build public charging infrastructure, our government is supporting Ontario’s growing end-to-end EV supply chain and ensuring EV drivers can confidently and conveniently power their journeys.”

This initiative is part of the government’s larger plan to support the adoption of electric vehicles and make EV charging infrastructure more accessible, which includes:

• The EV ChargeON program – a $91 million investment to support the installation of public EV chargers, including emerging V1G chargers to support grid-friendly deployment, outside of Ontario’s large urban centres, including at community hubs, Ontario’s highway rest areas, carpool parking lots, and Ontario Parks.
• The new Ultra-Low Overnight price plan which allows customers who use more electricity at night, including those charging their EV, to save up to $90 per year by shifting demand to the ultra-low overnight rate period when provincewide electricity demand is lower and to participate in programs that let them sell electricity back to the grid when appropriate.
• Making it more convenient for electric vehicle (EV) owners to travel the province with EV fast chargers now installed at all 20 renovated ONroute stations along the province’s busiest highways, the 400 and 401.

The initiative also builds on the government’s Driving Prosperity: The Future of Ontario’s Automotive Sector plan which aims to create a domestic EV battery ecosystem in the province, expand energy storage capacity, and position Ontario as a North American automotive innovation hub by working to support the continued transition to electric, low carbon, connected and autonomous vehicles.

Canada Net-Zero demands renewable energy deployment, leveraging hydropower to integrate wind, solar, and storage, scaling electrification, cutting oil and gas emissions, aligning policy, carbon pricing, and investment to deliver a clean grid by 2050.

Key Points

A national goal to cut emissions 40-45% by 2030 and reach economy-wide net-zero by 2050 through clean electrification.

✅ Hydropower balances intermittent wind and solar.

✅ Policy, carbon pricing, and investment accelerate deployment.

✅ Clean energy jobs surge as oil and gas decline.

As the UN climate talks draw near, Canada has enormous work left to do to reach its goals of reducing greenhouse gas emissions. Collectively, Canadians have to cut overall greenhouse-gas emissions by 40 to 45 per cent below 2005 levels by 2030 and achieve net-zero by 2050 across the economy.

And whereas countries like the U.K. have dramatically slashed their emissions levels, Canada's one of the few nations where emissions keep skyrocketing, and where fossil fuel extraction keeps increasing every year despite our climate targets.

In the upcoming online Conversations event on Thursday, 11 a.m. PT/2 p.m. ET, host and Canada's National Observer deputy managing editor David McKie will discuss how cleaning up Canada's electricity and renewable energy can put the country on track to hitting its targets with Clean Energy Canada executive director Merran Smith, Canadian Institute for Climate Choices senior economist Dale Beugin, and WaterPower Canada CEO Anne-Raphaëlle Audouin.

Getting to net-zero grid through renewable electricity
“If we wanted to be powered by 100 per cent renewable electricity, including proposals for a fully renewable electricity grid by 2030, Canada is one of the countries where this is actually possible,” said Audouin.

She says for that to happen, it would take a slate of clean energy providers working together to fill the gaps, rather than competing for market dominance.

“You couldn't power Canada just with wind and solar, even with batteries. That being said, renewables happen to work very well together ” she said. “Hydropower already makes up more than 90 per cent of Canada’s renewable generation and 60 per cent of the country’s total electricity needs are currently met thanks to this flexible, dispatchable, abundant source of baseload renewable electricity. It isn’t a stretch of the imagination to envision hydropower and wind and solar working increasingly together to clean up our grid. In fact, hydropower already backs up and allows intermittent renewable energies like wind and solar onto the grid.”

She noted that while hydropower alone won't be the solution, its long history and indisputable suite of attributes — hydroelectricity has been in Canada since the 1890s — will make it a key part of the clean energy transition required to replace coal, natural gas and oil, which still make up around 20 per cent of Canada's power sources.

Canada's vast access to water, wind, biomass, solar, geothermal, and ocean energy, and a federal government that has committed to climate goals, makes us well-positioned to lead the way to a net-zero future and eventually the electrification of our economy. So, what's holding the country back?

The new reality for renewables
According to Clean Energy Canada, it's possible to grow the clean energy sector, but only if businesses invest massively in renewables and governments give guidance and oversight informed by the implications of decarbonizing Canada's electricity grid research.

A recent modelling study from Clean Energy Canada and Navius Research exploring the energy picture here in Canada over the next decade shows our clean energy sector is expected to grow by about 50 per cent by 2030 to around 640,000 people. Already, the clean energy industry provides 430,500 jobs — more than the entire real estate sector — and that growth is expected to accelerate as our dependence on oil and gas decreases. In fact, clean energy jobs in Alberta are predicted to jump 164 per cent over the next decade.

Currently, provinces with the most hydropower generation are also the ones with the lowest electricity rates, reflecting that electricity has been a nationwide climate success in Canada. Wind and solar are now on par, or even more competitive, than natural gas, and that could have big implications for other major sectors of the economy. Grocery giant Loblaws (which owns brands including President's Choice, Joe Fresh, and Asian grocery chain T&T) deployed its fleet of fully electric delivery trucks in recent years, and Hydro-Québec just signed a $20-billion agreement to help power and decarbonize the state of New York over the next 25 years.

In The New Reality, Smith writes that many carbon-intensive industries, such as the mining sector, could also potentially benefit from the increased demand for certain natural resources — like lithium and nickel — as the world switches to electric vehicles and clean power.

“Oil and gas may have dominated Canada’s energy past, but it’s Canada’s clean energy sector that will define its new reality,” Smith emphasized.

Despite its vast potential to be one of the world's clean energy leaders, Canada has a long way to getting on the path to net zero. Even though the country is home to some of the world's leading cleantech companies, such as B.C.-based clean hydrogen fuel cell providers Ballard Power and Loop Energy and Nova Scotia-based carbon utilization company CarbonCure, the country continues to expand fossil fuel extraction to the point that emissions are projected to jump to around 1,500 MtCO2 worth by 2030.
