BWE - Wind power potential even higher than expected

California EV V2G explores bi-directional charging, smart charging, and demand response to enhance grid reliability. CPUC, PG&E, and automakers test incentives aligning charging with solar and wind, helping prevent blackouts and curtailment.

Key Points

California EV V2G uses two-way charging and smart incentives to support grid reliability during peak demand.

✅ CPUC studies feasibility, timelines, and cost barriers to V2G

✅ Incentives shift charging to align with solar, wind, off-peak hours

✅ High-cost bidirectional chargers and warranties remain hurdles

California energy regulators are eyeing the power stored in electric vehicles as they hunt for ways to avoid blackouts caused by extreme weather.

While few EV and their charging ports are equipped to deliver electricity back into the grid during emergencies, the California Public Utilities Commission wants more data on it as the agency rules on steps utilities must take to ensure they have enough power for this summer and next year. A draft CPUC decision due to be discussed this week asks about the feasibility of reversing the charge when needed (Energywire, March 8).

“Very few [EVs], maybe a couple of thousand at the most, can give power to the grid, and even fewer are connected into a charger that can do it,” said Gil Tal, director of the Plug-in Hybrid & Electric Vehicle Research Center at the University of California, Davis. EVs that feature the ability “have it at a more experimental level.”

The issue arises as California, where about half of all U.S. EVs are purchased, examines what role the vehicles can play in keeping lights on and refrigerators running and how a much bigger grid will support them in the long term. Even if grid operators can’t pull from EV batteries en masse, experts say cash and other incentives can prompt drivers to shift charging times, boosting grid stability.

“What we can do is not charge the electric cars at times of high demand” such as during heat waves, Tal said.

The EV focus comes after California’s grid manager last summer imposed rolling blackouts when power supplies ran short during a record-shattering heat wave. State energy regulators across the U.S., as EVs challenge state grids, are also looking at their disaster preparedness as Texas recovers from a winter storm last month that cut off electricity for more than 4 million homes and businesses there.

California’s EV efforts can help other states as they add more renewable power to their grids, said Adam Langton, energy services manager at BMW of North America.

That automaker ran a pilot program with San Francisco-based utility Pacific Gas & Electric Co. (PG&E) looking at whether money and other incentives could prompt EV drivers to charge their cars at different times. The payments successfully shifted charging to the middle of the night, when wind power often is plentiful. It also moved some repowering to mornings and early afternoons, when there’s abundant solar energy.

“That can be a tool that the utilities can use to deal with supply issues,” Langton said. “What our research has shown is that vehicles can contribute to [conservation] needs and emergency supply by shifting their charging time.”

Such measures can also help states avoid having to curtail solar production on days when there’s more generation than needed. On many bright days, California has more solar power than it can use.

“As more states add more renewable energy, we think that they’re going to find that EVs complement that really well with smart charging, because grid coordination can get that charging to align with the renewable energy,” Langton said. “It allows to add more and more renewable energy.”

High-cost equipment a hurdle
The CPUC at a future workshop plans to collect information on leveraging EVs to head off power shortages at key times.

But Tal said it will probably take a decade to get enough EVs capable of exporting electricity back to utilities “in high numbers that can make an impact on the grid.”

Barriers to reaching such “vehicle to grid” integration are technical and economic, he said. EVs export direct current and need a device on the other side that can convert it to alternating current, similar to a solar power inverter for rooftop panels.

However, the equipment known as a V2G capable charger is costly. It ranges from $4,500 to $5,500, according to a 2017 National Renewable Energy Laboratory report.

PG&E and Los Angeles-based Southern California Edison already have “expressed doubt that short-term measures could be developed in time to expand EV participation by summer 2021” in V2G programs, the draft CPUC proposal said. The utilities suggested instead that the agency encourage EV owners to participate in initiatives where they’d get paid for reducing power consumption or sell electricity back to the grid when needed, known as demand response programs.

Still, almost all major EV automakers are looking at two-directional charging, Tal said.

“The incentive is you can get more value for the car,” he said. “The disincentive is you add more miles in a way on the car,” because an owner would be discharging to the grid and re-charging, and “the battery has limited life.”

And right now, discharging a vehicle to the grid would violate many warranties, he said. Car manufacturers would need to agree to change that and could call for compensation in return.

Meanwhile, San Diego Gas & Electric Co., a Sempra Energy subsidy, plans to launch a pilot looking at delivering power to the grid from electric school buses. The six buses in the pilot transport students in El Cajon, Calif., east of San Diego.

“The buses are perfect because of their big batteries and predictable schedule,” Jessica Packard, SDG&E spokesperson, said in an email. “Ultimately, we hope to scale up and deploy these kinds of innovations throughout our grid in the future.”

She declined to say how much power the buses could deliver because the project isn’t yet operating. It’s set to start later this year.

Mobility needs
While BMW and PG&E did not review vehicle-to-grid power transfers in their own 2017 research ending last year, one study in Delaware did. But it was in a university setting about eight years ago and didn’t look at actual drivers, said Langton with BMW.

In their own findings from the San Francisco Bay Area pilot program, BMW and PG&E found that incentives could quickly change driver behavior in terms of charging.

Technology helps: Most new EVs have timers that allow the driver to control when to charge and when to stop charging. Langton said the pilot program got drivers to have their cars charge from roughly 2 to 6 a.m., when electricity rates typically are lowest.

There can be a lot of solar energy during the day, but in summer, optimum charging times get more complicated in California, he said. People want to run their air conditioners during peak heat hours, so it’s important to be able to get EV drivers to shift to less congested times, he said.

With the right incentives or messaging, Langton said, the pilot persuaded drivers to move charging from 10 a.m. to 2 p.m. or noon to 4 p.m. BMW technology allowed for detailed information on battery charge level, ideal charging times and other EV data to be transmitted electronically after plugging in.

The findings are a good first step toward future vehicle-to-grid integration, Langton added.

“One of the things we really pay attention to when we do smart charging is, ‘How does the driver’s mobility needs figure into shifting their charging?'” he said. “We want to make sure that our customers can always do the driving that they need to do.”

The pilot included safeguards such as an opt-out button if the driver wanted to charge immediately. It also made sure the vehicle had a certain level of minimum charge — 15% to 20% — before the delayed smart charging kicked in.

Vehicle-to-grid technology would need to wrestle with the same concepts in a different way. If a car is getting discharged, the driver would want assurances its battery wouldn’t dip below a level that meets their mobility needs, Langton said.

“If that happened even once to a customer, they would probably not want to participate in these programs in the future,” he said.

One group adding charging stations across the country said it isn’t tweaking pricing based on when drivers charge. That’s to help grow EV purchases, said Robert Barrosa, senior director of sales and marketing at Volkswagen AG subsidiary Electrify America, which operates about 450 charging stations in 45 states.

The company has installed battery storage at more than 100 sites to make sure they can provide power at consistent prices even if California or another state calls for energy conservation.

“It’s very important for vehicle adoption that the customer have that,” Barrosa said.

The company could sell that battery storage back to the grid if there are shortfalls, but some market changes are needed first, particularly in California, he said. That’s because the company buys electricity on the retail side but would be sending it back into the wholesale market.

With that cost differential, Barrosa said, “it doesn’t make sense.”

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."

Texas Battery Storage Investment Boom draws BlackRock, SK, and UBS, leveraging ERCOT price volatility, renewable energy growth, and utility-scale energy storage arbitrage to enhance grid reliability, resilience, and double-digit returns across high-demand nodes.

Key Points

Texas sees a rush into battery storage, using ERCOT price spreads to bolster grid reliability and earn about 20% returns.

✅ Investors exploit price volatility, peak-demand spreads.

✅ Utility-scale storage enhances ERCOT reliability.

✅ Top players: BlackRock, SK E&S, UBS; 700 MW deals.

BlackRock, Korea's SK, Switzerland's UBS and other companies are chasing an investment boom in battery storage plants in Texas, lured by the prospect of earning double-digit returns from the power grid problems plaguing the state, according to project owners, developers and suppliers.

Projects coming online are generating returns of around 20%, compared with single digit returns for solar and wind projects, according to Rhett Bennett, CEO of Black Mountain Energy Storage, one of the top developers in the state.

"Resolving grid issues with utility-scale energy storage is probably the hottest thing out there,” he said.

The rapid expansion of battery storage could help, through efforts like a virtual power plant initiative in Texas, prevent a repeat of the February 2021 ice storm and grid collapse which killed 246 people and left millions of Texans without power for days.

The battery rush also puts the Republican-controlled state at the forefront of President Joe Biden's push to expand renewable energy use.

Power prices in Texas can swing from highs of about $90 per megawatt hour (MWh) on a normal summer day to nearly $3,000 per MWh when demand surges on a day with less wind power, a dynamic tied to wind curtailment on the Texas grid according to a simulation by the federal government's U.S. Energy Information Administration.

That volatility, a product of demand and higher reliance on intermittent wind and solar energy, has fueled a rush to install battery plants, aided by falling battery costs, that store electricity when it is cheap and abundant and sell when supplies tighten and prices soar.

Texas last year accounted for 31% of new U.S. grid-scale energy storage, with much of it pairing storage with solar, according to energy research firm Wood Mackenzie, second only to California which has had a state mandate for battery development for a decade.

And Texas is expected to account for nearly a quarter of the U.S. grid-scale storage market over the next five years, a trajectory consistent with record U.S. solar-plus-storage growth noted by analysts, according to Wood Mackenzie projections shared with Reuters.

Developers and energy traders said locations offering the highest returns -- in strapped areas of the grid -- will become increasingly scarce as more storage comes online and, as diversifying resources for better projects suggests, electricity prices stabilize.

Texas lawmakers this week voted to provide new subsidies for natural gas power plants in a bid to shore up reliability. But the legislation also contains provisions that industry groups said could encourage investment in battery storage by supporting 'unlayering' peak demand approaches.

Amid the battery rush, BlackRock acquired developer Jupiter Power from private equity firm EnCap Investments late last year. Korea's SK E&S acquired Key Capture Energy from Vision Ridge Partners in 2021 and UBS bought five Texas projects from Black Mountain last year for a combined 700 megawatts (MW) of energy storage. None of the sales' prices were disclosed.

SK E&S said its acquisition of Key Capture was part of a strategy to invest in U.S. grid resiliency.

"SK E&S views energy storage solutions in Texas and across the U.S. as a core technology that supports a new energy infrastructure system to ensure American homes and businesses have affordable power," the company said in a statement.

OEB Energy Storage Integration advances DERs and battery storage through CDM guidelines, streamlined connection requirements, IESO-aligned billing, grid modernization incentives, and the Innovation Sandbox, providing regulatory clarity and consumer value across Ontario's electricity system.

Key Points

A suite of OEB initiatives enabling storage and DERs via modern rules, cost recovery, billing reforms, and pilots.

✅ Updated CDM guidelines recognize storage at all grid levels.

✅ Standardized connection rules for DERs effective Oct 1, 2022.

✅ Innovation Sandbox supports pilots and temporary regulatory relief.

The energy sector is in the midst of a significant transition, where energy storage is creating new opportunities to provide more cost-effective, reliable electricity service. The OEB recognizes it has a leadership role to play in providing certainty to the sector while delivering public value, and a responsibility to ensure that the wider impacts of any changes to the regulatory framework, including grid rule changes, are well understood. 

Accordingly, the OEB has led a host of initiatives to better enable the integration of storage resources, such as battery storage, where they provide value for consumers.

Energy storage integration – our journey 
We have supported the integration of energy storage by:

Incorporating energy storage in Conservation and Demand Management (CDM) Guidelines for electricity distributors. In December 2021, the OEB released updated CDM guidelines that, among other things, recognize storage – either behind-the-meter, at the distribution level or the transmission level – as a means of addressing specific system needs. They also provide options for distributor cost recovery, aligning with broader industrial electricity pricing discussions, where distributor CDM activities also earn revenues from the markets administered by the Independent Electricity System Operator (IESO).
 
Modernizing, standardizing and streamlining connection requirements, as well as procedures for storage and other DERs, to help address Ontario's emerging supply crunch while improving project timelines. This was done through amendments to the Distribution System Code that take effect October 1, 2022, as part of our ongoing DER Connections Review.
 
Facilitating the adoption of Distributed Energy Resources (DERs), which includes storage, to enhance value for consumers by considering lessons from BESS in New York efforts. In March 2021, we launched the Framework for Energy Innovation consultation to achieve that goal. A working group is reviewing issues related to DER adoption and integration. It is expected to deliver a report to the OEB by June 2022 with recommendations on how electricity distributors can assess the benefits and costs of DERs compared to traditional wires and poles, as well as incentives for distributors to adopt third-party DER solutions to meet system needs.
 
Examining the billing of energy storage facilities. A Generic Hearing on Uniform Transmission Rates is underway. In future phases, this proceeding is expected to examine the basis for billing energy storage facilities and thresholds for gross-load billing. Gross-load billing demand includes not just a customer’s net load, but typically any customer load served by behind-the-meter embedded generation/storage facilities larger than one megawatt (or two megawatts if the energy source is renewable).
 
Enabling electricity distributors to use storage to meet system needs. Through a Bulletin issued in August 2020, we gave assurance that behind-the-meter storage assets may be considered a distribution activity if the main purpose is to remediate comparatively poor reliability of service.
 
Offering regulatory guidance in support of technology integration, including for storage, through our OEB Innovation Sandbox, as utilities see benefits across pilot deployments. Launched in 2019, the Innovation Sandbox can also provide temporary relief from a regulatory requirement to enable pilot projects to proceed. In January 2022, we unveiled Innovation Sandbox 2.0, which improves clarity and transparency while providing opportunities for additional dialogue. 
Addressing the barriers to storage is a collective effort and we extend our thanks to the sector organizations that have participated with us as we advanced these initiatives. In that regard, we provided an update to the IESO on these initiatives for a report it submitted to the Ministry of Energy, which is also exploring a hydrogen economy to support decarbonization.

EV Grid Readiness means utilities preparing the power grid for electric vehicles with smart charging, demand response, V2G, managed load, and renewable integration to maintain reliability, prevent outages, and optimize infrastructure investment.

Key Points

EV Grid Readiness is utilities' ability to support mass EV charging with smart load control, V2G, and grid upgrades.

✅ Managed charging shifts load off-peak to reduce stress and costs

✅ V2G enables EVs to supply power and balance renewables

✅ Utilities plan upgrades, rate design, and demand response

There's little doubt that the automobile industry is beginning the greatest transformation it has ever seen as the American EV boom gathers pace. The internal combustion engine, the heart of the automobile for over 100 years, is being phased out in favor of battery electric powered vehicles. 

Industry experts know that it's no longer a question of will electric vehicles take over, the only question remaining is how quickly will it happen. If electric vehicle adoption accelerates faster than many have predicted, can the power grid, and especially state power grids across the country, handle the additional load needed to "fuel" tens of millions of EVs?

There's been a lot of debate on this subject, with, not surprisingly, those opposed to EVs predicting doomsday scenarios including power outages, increased electricity rates, and frequent calls from utilities asking customers to stop charging their cars.

There have also been articles written that indicate the grid will be able to handle the increased power demand needed to fuel a fully electric transportation fleet. Some even explain how electric vehicles will actually help grid stability overall, not cause problems.

So we decided to go directly to the source to get answers. We reached out to two industry professionals that aren't just armchair experts. These are two of the many people in the country tasked with the assignment of making sure we don't have problems as more and more electric vehicles are added to the national fleet. 

"Let's be clear. No one is forcing anyone to stop charging their EV." - Eric Cahill, speaking about the recent request by a California utility to restrict unnecessary EV charging during peak demand hours when possible

Both Eric Cahill, who is the Strategic Business Planner for the Sacramento Municipal Utility District in California, and John Markowitz, the Senior Director and Head of eMobility for the New York Power Authority agreed to recorded interviews so we could ask them if the grid will be ready for millions of EVs.  

Both Cahill and Markowitz explained that, while there will be challenges, they are confident that their respective districts will be ready for the additional power demand that electric vehicles will require. It's also important to note that the states that they work in, California and New York, with California expected to need a much bigger grid to support the transition, have both banned the sale of combustion vehicles past 2035. 

That's important because those states have the most aggressive timelines to transition to an all-electric fleet, and internationally, whether the UK grid can cope is a parallel question, so if they can provide enough power to handle the increased demand, other states should be able to also. 

We spoke to both Cahill and Markowitz for about thirty minutes each, so the video is about an hour long. We've added chapters for those that want to skip around and watch select topics. 

We asked both guests to explain what they believe some of the biggest challenges are, including how energy storage and mobile chargers could help, if 2035 is too aggressive of a timeline to ban combustion vehicles, and a number of other EV charging and grid-related questions. 

Neither of our guests seemed to indicate that they were worried about the grid crashing, or that 2035 was too soon to ban combustion vehicles. In fact, they both indicated that, since they know this is coming, they have already begun the planning process, with proper management in place to ensure the lights stay on and there are no major electricity disruptions caused by people charging their cars. 

So check out the video and let us know your thoughts. This has been a hot topic of discussion for many years now. Now that we've heard from the people in charge of providing us the power to charge our EVs, can we finally put the concerns to rest now? As always, leave your comments below; we want to hear your opinions as well.

Harbour Air Electric Seaplanes pioneer zero-emission aviation with battery-powered de Havilland Beaver flights, pursuing Transport Canada certification for safe, fossil fuel-free service across Vancouver Island routes connecting Vancouver, Victoria, Nanaimo, and beyond.

Key Points

Battery-powered, zero-emission floatplanes by Harbour Air pursuing Transport Canada certification to carry passengers.

✅ 29-minute test flight on battery power alone

✅ New lighter, longer-lasting battery supplier partnership

✅ Aiming to electrify entire 42-aircraft Beaver/Otter fleet

Float plane operator Harbour Air is getting closer to achieving its goal of flying to and from Vancouver Island without fossil fuels, following its first point-to-point electric flight milestone.

A recent flight of the company’s electric de Havilland Beaver test plane saw the aircraft remain aloft for 29 minutes on battery power alone, a sign of an emerging aviation revolution underway.

Harbour Air president Randy Wright says the company has joined with a new battery supplier to provide a lighter and longer-lasting power source, a high-flying example of research investment in the sector.

The company hopes to get Transport Canada certification to start carrying passengers on electric seaplanes by 2023, as projects like the electric-ready Kootenay Lake ferry come online.

"This is all new to Transport, so they've got to make sure it's safe just like our aircraft that are running today,” Wright said Wednesday. “They're working very hard at this to get this certified because it's a first in the world."

Parallel advances in marine electrification, such as electric ships on the B.C. coast, are informing clean-transport goals across the province.

Before the pandemic, Harbour Air flew approximately 30,000 commercial flights annually, along corridors also served by BC Ferries hybrid ships today, between Vancouver, Victoria, Nanaimo, Whistler, Seattle, Tofino, Salt Spring Island, the Sunshine Coast and Comox.

Wright says the company plans to eventually electrify its entire fleet of 42 de Havilland Beaver and Otter aircraft, reflecting a broader shift that includes CIB-backed electric ferries in B.C.
