0 to 180 km in 10 minutes: B.C. Hydro rolls out faster electric vehicle charging

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.

California EV Sales 2023 show rising BEV market share, strong Tesla Model Y and Model 3 demand, hybrid growth, and ICE decline, per CNCDA Q3 data, underscoring California auto trends and ZEV policy momentum.

Key Points

BEVs hit 21.5% YTD in 2023 (22.3% in Q3); 35.4% with hybrids, as ICE share fell and Tesla led the California market.

✅ BEVs 21.5% YTD; 22.3% in Q3 per CNCDA data

✅ Tesla Model Y, Model 3 dominate; 62.9% BEV share

✅ ICE share down to 64.6%; hybrids lift to 35.4% YTD

The California New Car Dealers Association (CNCDA) reported on November 1, 2023, that sales of battery electric cars accounted for 21.5% of new car sales in the Golden State during the first 9 months of the year and 22.3% in the third quarter. At the end of Q3 in 2022, sales of electric cars stood at 16.4%. In 2021, that number was 9.1%. So, despite all the weeping and wailing and gnashing of teeth lately about green new car wreck warnings in some coverage, the news is pretty good, at least in California.

When hybrid and hydrogen fuel cell vehicles are included in the calculations, the figure jumps up 35.4% for all vehicles sold year to date in California. Not surprisingly this means EVs still trail gas cars in the state, with the CNCDA reporting ICE market share (including gasoline and diesel vehicles) was 64.6% so far this year, down from 71.6% in 2022 and 88.4% in 2018.

California is known as the vanguard for automotive trends in the country, with shifts in preferences and government policy eventually spreading to the rest of the country. While the state’s share of electric cars exceeds one fifth of all vehicles sold year to date, the figure for the US as a whole stands at 7.4%, with EV sales momentum into 2024 continuing nationwide. California has banned the sale of gas-powered vehicles starting in 2035, and its push toward electrification will require a much bigger grid to support charging, although the steady increase in the sale of electric cars suggests that ban may never need to be implemented as people embrace the EV revolution.

Not surprisingly, when digging deeper into the sales data, the Tesla Model Y and Model 3 dominate sales in the state’s electric car market this year, at 103,398 and 66,698 respectively. Tesla’s overall market share of battery electric car sales is at 62.9%. In fact, the Tesla Model Y is the top selling vehicle overall in California, followed by the Model 3, the Toyota RAV4 (40,622), and the Toyota Camry (39,293).

While that is good news for Tesla, its overall market share has slipped from 71.8% year to date last year at this time. Competing models from brands like Chevrolet, BMW, Mercedes, Hyundai, Volkswagen, and Kia have been slowly eating into Tesla’s market share. Overall, in California, Toyota is the sales king with 15% of sales, even as the state leads in EV charging deployment statewide, followed by Tesla at 13.5%. In the second quarter, Tesla narrowly edged out Toyota for top sales in the state before sales swung back in Toyota’s favor in the third quarter.

That being said, Tesla’s sales in the state climbed by 38.5% year to date, while Toyota’s actually shrank by 0.7%. Time will tell if Tesla’s popularity with the state’s car buyers improves and it can overtake Toyota for the 2023 crown, even as U.S. EV market share dipped in early 2024, or if other EV makers can offer better products at better prices and lure California customers who want to purchase electric cars away from the Tesla brand. Certainly, no company can expect to have two thirds of the market to itself forever.

Connected Home Energy Technologies integrate solar panels, smart meters, EV charging, battery storage, and IoT energy management to cut costs, optimize demand response, and monitor usage in real time for safer, lower-carbon homes.

Key Points

Devices and systems managing home energy: solar PV, smart meters, EV chargers, and storage to cut costs and emissions.

✅ Real-time visibility via apps, smart meters, and IoT sensors

✅ Integrates solar PV, batteries, and EV charging with the grid

✅ Enables demand response, lower bills, and lower carbon

Driven by advances in tech and the advent of high-speed internet connections, many of us now have easy access to a raft of information about the buildings we live in.

Thanks to the proliferation of hardware and software within the home, this trend shows no sign of letting up and comes in many different forms, from indoor air quality monitors to “smart” doorbells which provide us with visual, real-time notifications when someone is attempting to access our property.

Residential renewable electricity generation is also starting to gain traction, with a growing number of people installing solar panels in the hope of reducing bills and their environmental footprint.

In the U.S. alone, the residential solar market installed 738 megawatts of capacity in the third quarter of 2020, a 14% jump compared to the second quarter, according to a recent report from the Solar Energy Industries Association and Wood Mackenzie.

Earlier this month, California-headquartered SunPower — which specializes in the design, production and delivery of solar panels and systems — announced it was rolling out an app which will enable homeowners to assess and manage their energy generation, usage and battery storage settings with their mobile, as California looks to EVs for grid stability amid broader electrification.

The service will be available to customers using its SunPower Eqiunox system and represents yet another instance of how connected technologies can provide us with valuable information about how buildings operate.

Similar offerings in this increasingly crowded marketplace include so-called “smart” meters, which allow consumers to see how much energy they are using and money they are spending in real time.

Elsewhere products such as Hive, from Centrica, enable users to install a range of connected kit — from plugs and lighting to thermostats and indoor cameras — that can be controlled via an app on their cellphone and, in some cases, their voice. 

Connected car charging
Solar panels represent one way that sustainable tech can be integrated into homes. Other examples include the installation of charging points for electric vehicles, as EV growth challenges state grids in many markets.

With governments around the world looking to phase-out the sale of diesel and gasoline vehicles and encourage consumers to buy electric, and Model 3's utility impact underscoring likely shifts in demand, residential charging systems could become an integral part of the built environment in the years ahead.

Firms offering home-based, connected, charging include Pod Point and BP Pulse. Both of these services include apps which provide data such as how much energy has been used, the cost of charging and charge history.  

Another firm, Wallbox, recently announced it was launching its first electric vehicle charger for North American homes.

The company, which is based in Spain, said the system was compatible with all types of electric vehicles, would allow customers to schedule charges, and could be voice-controlled through Google Assistant and Amazon Alexa, while mobile energy storage promises added flexibility for strained grids.

Away from the private sector, governments are also making efforts to encourage the development of home charging infrastructure.

Over the weekend, U.K. authorities said the Electric Vehicle Homecharge Scheme — which gives drivers as much as £350 (around $487) toward a charging system — would be extended and expanded, targeting those who live in leasehold and rented properties, even as UK grid capacity for EVs remains under scrutiny.

Mike Hawes, chief executive of the Society of Motor Manufacturers and Traders, described the government’s announcement as “welcome and a step in the right direction.”

“As we race towards the phase out of sales of new petrol and diesel cars and vans by 2030, we need to accelerate the expansion of the electric vehicle charging network, and proper grid management can ensure EVs are accommodated at scale,” he added.

“An electric vehicle revolution will need the home and workplace installations this announcement will encourage, but also a massive increase in on-street public charging and rapid charge points on our strategic road network.”

Change afoot, but challenges ahead
As attempts to decarbonize buildings and society ramp up, the way our homes look and function could be on the cusp of quite a big shift.

“Grid-connected home generation technologies such as solar electric panels will be important in the shift to a 100% renewable electricity grid, but decarbonising the electricity supply is only one part of the transition,” Peter Tyldesley, chief executive of the Centre for Alternative Technology, told CNBC via email.

With reference to Britain, Tyldesley went on to explain how his organization envisaged “just under 10% of electricity in a future zero carbon society coming from solar PV, utilising 15-20% of … U.K. roof area.” This, he said, compared to over 75% of electricity coming from wind power. 

Heating, Tyldesley went on to state, represented “the bigger challenge.”

“To decarbonise the U.K.’s housing stock at the scale and speed needed to get to zero carbon, we’ll need to refurbish possibly a million houses every year for the next few decades to improve their insulation and airtightness and to install heat pumps or other non-fossil fuel heating,” he said.

“To do this, we urgently need a co-ordinated national programme with a commitment to multi-year government investment,” he added.

On the subject of buildings becoming increasingly connected, providing us with a huge amount of data about how they function, Tyldesley sought to highlight some of the opportunities this could create. 

“Studies of the roll out of smart metering technology have shown that consumers use less energy when they are able to monitor their consumption in real time, so this kind of technology can be a useful part of behaviour change programmes when combined with other forms of support for home efficiency improvements,” he said.

“The roll out of smart appliances can go one step further — responding to signals from the grid and, through vehicle-to-grid power, helping to shift consumption away from peak times towards periods when more renewable energy is available,” he added.

US Wind and Solar Outlook 2026 projects cheap renewables displacing coal and gas, with utility-scale additions, rooftop solar growth, improved grid reliability, and EV V2G integration accelerating decarbonization across the electricity market.

Key Points

An analysis forecasting wind and solar growth, displacing coal and gas as utility-scale and rooftop solar expand.

✅ Utility-scale solar installs avg 21 GW/yr through 2026.

✅ 37.7 GW wind in pipeline; 127.8 GW already online.

✅ Small-scale solar could near 100 TWh in 2026.

A recent report from the Institute for Energy Economics and Financial Analysis (IEEFA) predicts that cheap renewables in the form of wind and solar will push coal and gas out of the energy market space. Already at 9% of US generation, the report predicts that wind and solar will supply almost 30% of US electricity demand by 2026, consistent with renewables nearing one-fourth of U.S. generation projections for the near term.

“The Solar Energy Industries Association now expects utility-scale installations to average more than 21,000MW a year through 2026, following a year when U.S. solar generation rose 25% and with a peak of 25,000MW in 2023,” IEEFA writes. “Continued growth is also expected in U.S. wind generation, mirroring global trends where China's solar PV expansion outpaced all other fuels in 2016, with 37.7GW of new capacity already under construction or in advanced development, which would be added to 127.8GW in existing installed capacity.”

Meanwhile, with wind and solar growth booming, fossil fuels are declining, as renewables surpassed coal in 2022 nationwide. “Coal and natural gas are now locked into an essentially zero-sum game where increases in one fuel’s generation comes at the expense of the other. Together, they are not gaining market share, rather they are trading it back and forth, and the rapid growth in renewable generation will cut even deeper into the market share of both.”

And what of rooftop solar? Some states in Australia now have periods where the entire state grid is powered just by solar on the roofs of private citizens. As this revolution progresses in the USA, especially if a tenfold national solar push moves forward, what impact will it make on fossil fuel generators — which are expensive to build, expensive to maintain, expensive to fuel, and rely on an expensive distribution network.

“EIA estimates that this ‘small-scale solar’ produced 41.7 million MWh of power in 2020, when solar accounted for about 3% of U.S. electricity, a 19 percent increase from 2019. This growth will likely continue in the years ahead as costs continue to fall and concerns about grid reliability rise. Assuming a conservative 15 percent annual increase in small-scale solar going forward would push the sector’s generation to almost 100 million MWh in 2026.”

The Joker in the story might be the impact from electric vehicle adoption. Sales are set to surge and there’s more and more interest in V2G technology, even as wind and solar could provide 50% by 2050 in broader forecasts.

Germany Hydrogen Fuel Cell Market gains momentum as policy, mobility, and R&D align; National Hydrogen Strategy, regulatory frameworks, and cost-of-ownership advances boost heavy transport, while Europe races Asia amid battery-electric competition and infrastructure scale-up.

Key Points

It is Germany and Europe's hydrogen fuel cell ecosystem across policy, costs, R&D, and mobility and freight deployments.

✅ Policy support via National Hydrogen Strategy and tax incentives

✅ TCO parity improves for heavy transport vs other low-emission tech

✅ R&D targets higher temps, compactness for road, rail, sea, air

In a new report examining the status of the German and European hydrogen fuel cell markets, the German government-backed National Platform Future of Mobility (NPM) says there is “a good chance that fuel cell technology can achieve a break-through in mobile applications,” even as the age of electric cars accelerates across markets.

However, Europe must catch up with Asian countries, it adds, even as a push for electricity shapes climate policy. For Germany and Europe to take on a leading role in fuel cell technologies, their industries need to be strengthened and sustainably developed, the report finds. In its paper, the NPM Working Group 4 – which aims to secure Germany as a place for mobility, battery cell production, recycling, training and qualification – states that the “chances of fuel cell technology achieving a break-through in the automotive industry – even in Europe – are better than ever,” echoing recent remarks from BMW's chief about hydrogen's appeal.

The development, expansion and use of the technology in various applications are now supported by “a significantly modified regulatory framework and new political ambitions, as stipulated in the National Hydrogen Strategy,” while updated forecasts show e-mobility driving electricity demand in Germany, the report stresses. In terms of cost of ownership, “hydrogen solutions can hold their own compared to other technologies” and there are “many promising developments in the transport sector, especially in heavy transport.”

If research and development efforts can help optimise installation space and weight as well as increase the operating temperature of fuel cells, hydrogen solutions can also become attractive for maritime, rail and air transport, even as other electrochemical approaches, such as flow battery cars, progress, the report notes. Tax incentives -- such as the Renewable Energy Sources Act (EEG) surcharge exemption for green hydrogen -- can contribute to the technology’s appeal, it adds.

Fuel cell drives are often seen as a way to decarbonise certain areas of transport, such as heavy trucks. However, producing the hydrogen in a sustainable way consumes a lot of renewable electricity that power companies must supply in other sectors, and experts say electricity vs hydrogen trade-offs favor battery-electric trucks because they are much cheaper to run than other low-emission technologies, including fuel cells.

U.S. Renewable Energy Record 28% signals a cleaner power grid as wind, solar, and hydroelectric output soar; EIA data shows cost-competitive clean energy reshaping the electricity mix and reducing carbon emissions across regions.

Key Points

EIA-reported April share of electricity from wind, solar, and hydro, reflecting cost-driven growth in U.S. clean power.

✅ Wind, solar additions dominated recent U.S. capacity buildouts

✅ Lower levelized costs make renewables most competitive

✅ Seasonal factors and outages lowered fossil and nuclear output

The amount of electricity generated by renewable resources hit a record 28% in April, a breakthrough number that shows how important renewable energy has become in U.S. energy markets as it surpassed coal in 2022 overall.

"It's a 'Wow' moment," said Peter Kelly-Detwiler, an energy analyst and author of "The Energy Switch," a recent book about the transition to a carbon-free energy economy.

The percentage of U.S. electricity produced by renewable energy from wind, solar and hydroelectric dams has been steadily rising, from 8.6% in April 2001 to this April's 28%. Those numbers were released this week by the U.S. Energy Information Administration, which tracks energy data for the nation.

What explains the surge?
There are several reasons. At the top is that wind and solar installations dominated U.S. energy buildouts.

"Basically, the only things we've added to the grid in the past decade are wind, solar and natural gas," said Harrison Fell, an economist and engineer at Columbia University, where he co-leads the Power Sector and Renewables Research Initiative.

That's happening for two reasons. The first is cost. Renewables are simply the most economically competitive power currently available, Kelly-Detwiler said.

In 2021, the cost of producing a megawatt-hour of electricity from a new wind turbine was $26 to $50. The same amount of electricity from the cheapest type of natural gas plant ranged from $45 to $74, according to Lazard, a financial advisory firm that publishes annual estimates of the cost of producing electricity. 

Federal and state mandates and incentives to increase the amount of clean energy used also help, Fell said, as renewables reached 25.5% of U.S. electricity recently. 

"When you do the math on what's the most profitable thing to add, it's often going to be wind and solar at this stage," he said.

Was weather a factor?
Yes. April tends to be a particularly windy month, and this spring was windier than most, Fell said.

There's also less power coming into the grid from fossil fuels and nuclear in the spring. That's because electricity demand is generally lower because of the mild weather and fossil fuel and nuclear power plants use the time for maintenance and refueling, which reduces their production, he said.

Another surprise was that in April, wind and solar power together produced more electricity than nuclear plants nationwide. 

Historically, nuclear power plants, which are carbon-neutral, have reliably produced about 20% of America's electricity. In April that number dropped to 18% while wind and solar combined stood at 19.6%.

The nuclear decrease is partly a result of the shutdown of two plants in the past year, Indian Point in New York state and Palisades in Michigan, as well as scheduled closures for maintenance.

Will the trend continue?
When all U.S. carbon-neutral energy sources are added together – nuclear, wind, hydroelectric and solar – almost 46% of U.S. electricity in April came from sources that don't contribute greenhouse gases to the environment, federal data shows.  

"It's a milestone," Kelly-Detwiler said. "But in a few years, we'll look back and say, 'This was a nice steppingstone to the next 'Wow!' moment."
