Man died when shocked by power line

Costa Rica Renewable Energy Record highlights 99.99% clean power in May 2019, driven by hydropower, wind, solar, geothermal, and biomass, enabling ICE REM electricity exports and reduced rates from optimized generation totaling 984.19 GWh.

Key Points

May 2019 benchmark: Costa Rica generated 99.99% of 984.19 GWh from renewables, shifting from imports to regional exports.

✅ 99.99% renewable share across hydro, wind, solar, geothermal, biomass

✅ 984.19 GWh generated; ICE suspended imports and exported via REM

✅ Geothermal output increased to offset dry-season hydropower variability

During the whole month of May 2019, Costa Rica generated a total of 984.19 gigawatt hours of electricity, the highest in the country’s history. What makes this feat even more impressive is the fact that 99.99% of this energy came from a portfolio of renewable sources such as hydropower, wind, biomass, solar, and geothermal.

With such a high generation rate, the state power company Instituto Costariccense de Electricidad (ICE) were able to suspend energy imports from the first week of May and shifted to exports, while U.S. renewable electricity surpassed coal in 2022 domestically. To date, the power company continues to sell electricity to the Regional Electricity Market (REM) which generates revenues and is likely to reduce local electricity rates, a trend echoed in places like Idaho where a vast majority of electricity comes from renewables.

The record-breaking power generation was made possible by optimization of the country’s renewable sources, much as U.S. wind capacity surpassed hydro capacity at the end of 2016 to reshape portfolios. As the period coincided with the tail end of the dry season, the geothermal quota had to be increased.

Costa Rica remains a leader in renewable power generation, whereas U.S. wind generation has become the most-used renewable source in recent years. In 2015, more than 98% of the country’s electrical generation came from renewable sources, while U.S. renewables hit a record 28% in April in one recent benchmark. Through the years, this figure has remained fairly constant despite dry bouts caused by the El Niño phenomenon, and U.S. solar generation also continued to rise.

Newfoundland and Labrador Energy Efficiency faces low rankings yet signs of progress: heat pumps, EV charging networks, stricter building codes, electrification to tap Muskrat Falls power and cut greenhouse gas emissions and energy poverty.

Key Points

Policies and programs improving N.L.'s energy use via electrification, EVs, heat pumps, and stronger building codes.

✅ Ranks last provincially but showing policy momentum

✅ Heat pump grants and EV charging network underway

✅ Stronger building codes and electrification can cut emissions

Ah, another day, another depressing study that places Newfoundland and Labrador as lagging behind the rest of Canada.

We've been in this place before — least-fit kids, lowest birthrate — and now we can add a new dubious distinction to the pile: a ranking of the provinces according to energy efficiency placed Newfoundland and Labrador last.

Efficiency Canada released its first-ever provincial scorecard Nov. 20, comparing energy efficiency policies among the provinces. With energy efficiency a key part of reducing greenhouse gas emissions, Newfoundland and Labrador sat in 10th place, noted for its lack of policies on everything from promoting EV uptake in Atlantic Canada to improving efficient construction codes.

But before you click away to a happier story (about, say, a feline Instagram superstar) one of the scorecard's authors says there's a silver lining to the statistics.

"It's not that Newfoundland and Labrador is doing anything badly; it's just that it could do more," said Brendan Haley, the policy director at Efficiency Canada, a new think tank based at Carleton University.

"There's just a general lack of attention to implementing efficiency policies relative to other jurisdictions, including New Brunswick's EV rebate programs on transportation."

Looking at the scorecard and comparing N.L. with British Columbia, which snagged the No. 1 spot, isn't a great look. B.C. scored 56 points out of a possible 100, while N.L. got just 15.

Haley pointed out that B.C.'s provincial government is charting progress toward 2032, when all new builds will have to be net-zero energy ready; that is, buildings that can produce as much clean energy as they consume.  

While it might not be feasible to emulate that to a T here, Haley said the province could be mandating better energy efficiency standards for new, large building projects, and, at the same time, promote electrification of such projects as a way to soak up some of that surplus Muskrat Falls electricity.

Staring down Muskrat's 'extraordinary' pressure on N.L. electricity rates

It's impossible to talk about energy efficiency in N.L. without considering that dam dilemma. As Muskrat Falls comes online, likely at the end of 2020, customer power rates are set to rise in order to pay for it, and the province is still trying to figure out the headache that is rate mitigation.

"There is a strategic choice to be made in Newfoundland and Labrador," Haley told CBC Radio's On The Go.

While having more customers using Muskrat Falls power can help with rate mitigation, including through initiatives like N.L.'s EV push to grow demand, Haley noted simply using its excess electricity for the sake of it isn't a great goal.

"That should not be an excuse, I think, to almost have a policy of wasting energy on purpose, or saying that we don't need programs that help save electricity anymore," he said.

Energy poverty
Lots of N.L. homeowners are currently feeling a chill from the spectre of rising electricity rates.

Of course, that draft could be coming from a poorly insulated and heated house, as Efficiency Canada noted 38 per cent of all households in N.L. live in what it calls "energy poverty," where they spend more than six per cent of their after-tax income on energy — that's the second highest such rate in the country.

That poverty speaks for a need for N.L.to boost efficiency incentives for vulnerable populations, although Haley noted the government is making progress. The province recently expanded its home energy savings program, doubling in the last budget year to $2 million, which gives grants to low income households for upgrades like insulation.

Can you guess what products are selling like hotcakes as Muskrat Falls looms? Heat pumps

And since Efficiency Canada compiled its scorecard, the province has introduced a $1-million heat pump program, in which 1,000 homeowners could receive $1,000 toward the purchase of a heat pump. 

That program began accepting applications Oct. 15, and one month in, has had 682 people apply, according to the Department of Municipal Affairs and Environment, along with thousands of inquiries.

Heat pump popularity
Even without that program, heat pump sales have skyrocketed in the province since 2017. That popularity doesn't come as much of a surprise to Darren Brake, the president of KSAB Construction in Corner Brook.

With more than two decades in the home building business, he's been seeing consumer demand for home energy efficiency rise to the point where a year ago, his company transitioned into only building third-party certified energy efficient homes.

"Everybody's really concerned about the escalating power costs and energy costs, I assume because of Muskrat Falls," he said.

"It's evolving now, as we speak. Everybody is all about that monthly payment."

Brake uses spray foam installation in every house he builds, to seal up any potential leaks. Without sealing the building envelope, he says, a heat pump is far less efficient. (Lindsay Bird/CBC)
And in the weakest housing market in the province in half a century, Brake has been steadily moving his, building and selling seven in the last year.

Brake's houses include heat pumps, but he said the real savings come from their heavily insulated walls, roof and floors. Homeowners looking to install a heat pump in their leaky old house, he said, won't see lower power bills in quite the same way.

"They are energy efficient, but it's more about the building envelope to make a home efficient and easy to heat. You can put a heat pump in an older home that leaks a lot of air, and you won't get the same results," he said.

Charging network coming
The other big piece to the efficiency puzzle — in the scorecard's eyes — is electric vehicles. Those could, again, use some of that Muskrat Falls energy, as well as curtail gas guzzling, but Efficiency Canada pointed to a lack of policies and incentives surrounding electrifying transportation, such as Nova Scotia's vehicle-to-grid pilot that illustrates innovation elsewhere.

Unlike Quebec or B.C., the province doesn't offer a rebate for buying EVs, even as N.W.T. encourages EVs through targeted measures, and while electric vehicles got loud applause at the House of Assembly last week, it was absent of any policy or announcement beyond the province unveiling a EV licence plate design to be used in the near future.

Electric-vehicle charging network planned for N.L. in 2020

But since the scorecard was tallied, NL Hydro has unveiled plans for a Level 3 charging network for EVs across the island, dependent on funding, with N.L.'s first fast-charging network seen as just the beginning for local drivers.

NL Hydro says while its request for proposals for an island-wide charging network closed earlier in November, there is no progress update yet, even as N.B.'s fast-charging rollout advances along the Trans-Canada. (Credit: iStock/Getty Images)
That cash appears to still be in limbo, as "we are still progressing through the funding process," said an NL Hydro spokesperson in an email, with no "additional details to release at this time."

Still, the promise of a charging network — plus the swift uptake on the heat pump program — could boost N.L.'s energy efficiency scorecard next time it's tallied, said Haley.

"It is encouraging to see the province moving forward on smart and efficient electrification," he said.

COVID-19 Impact on Global Oil Demand 2020 signals an IEA forecast of declining consumption as travel restrictions curb transport fuels, disrupt energy markets, and shift OPEC and non-OPEC supply dynamics amid economic slowdown.

Key Points

IEA sees first demand drop since 2009 as COVID-19 curbs travel, weakening transport fuels and unsettling energy markets.

✅ IEA base case: 2020 demand at 99.9 mb/d, down 90 kb/d from 2019.

✅ Travel restrictions hit transport fuels; China drives the decline.

✅ Scenarios: low -730 kb/d; high +480 kb/d in 2020.

Global oil demand is expected to decline in 2020 as the impact of the new coronavirus (COVID-19) spreads around the world, constricting travel and broader economic activity, according to the International Energy Agency’s latest oil market forecast.

The situation remains fluid, creating an extraordinary degree of uncertainty over what the full global impact of the virus will be. In the IEA’s central base case, even as global CO2 emissions flatlined in 2019 according to the IEA, demand this year drops for the first time since 2009 because of the deep contraction in oil consumption in China, and major disruptions to global travel and trade.

“The coronavirus crisis is affecting a wide range of energy markets – including coal-fired electricity generation, gas and renewables – but its impact on oil markets is particularly severe because it is stopping people and goods from moving around, dealing a heavy blow to demand for transport fuels,” said Dr Fatih Birol, the IEA’s Executive Director. “This is especially true in China, the largest energy consumer in the world, which accounted for more than 80% of global oil demand growth last year. While the repercussions of the virus are spreading to other parts of the world, what happens in China will have major implications for global energy and oil markets.”

The IEA now sees global oil demand at 99.9 million barrels a day in 2020, down around 90,000 barrels a day from 2019. This is a sharp downgrade from the IEA’s forecast in February, which predicted global oil demand would grow by 825,000 barrels a day in 2020.

The short-term outlook for the oil market will ultimately depend on how quickly governments move to contain the coronavirus outbreak, how successful their efforts are, and what lingering impact the global health crisis has on economic activity.

To account for the extreme uncertainty facing energy markets, the IEA has developed two other scenarios for how global oil demand could evolve this year. In a more pessimistic low case, global measures fail to contain the virus, and global demand falls by 730,000 barrels a day in 2020. In a more optimistic high case, the virus is contained quickly around the world, and global demand grows by 480,000 barrels a day.

“We are following the situation extremely closely and will provide regular updates to our forecasts as the picture becomes clearer,” Dr Birol said. “The impact of the coronavirus on oil markets may be temporary. But the longer-term challenges facing the world’s suppliers are not going to go away, especially those heavily dependent on oil and gas revenues. As the IEA has repeatedly said, these producer countries need more dynamic and diversified economies in order to navigate the multiple uncertainties that we see today.”

The IEA also published its medium-term outlook examining the key issues in global demand, supply, refining and trade to 2025, as well as the trajectory of the global energy transition now shaping markets. Following a contraction in 2020 and an expected sharp rebound in 2021, yearly growth in global oil demand is set to slow as consumption of transport fuels grows more slowly and as national net-zero pathways, with Canada needing more electricity to reach net-zero influencing power demand, according to the report. Between 2019 and 2025, global oil demand is expected to grow at an average annual rate of just below 1 million barrels a day. Over the period as whole, demand rises by a total of 5.7 million barrels a day, with China and India accounting for about half of the growth.

At the same time, the world’s oil production capacity is expected to rise by 5.9 million barrels a day, with more than three-quarters of it coming from non-OPEC producers, the report forecasts. But production growth in the United States and other non-OPEC countries is set to lose momentum after 2022, amid shifts in Wall Street's energy strategy linked to policy signals, allowing OPEC producers from the Middle East to turn the taps back up to help keep the global oil market in balance.

The medium-term market report, Oil 2020, also considers the impact of clean energy transitions on oil market trends. Demand growth for gasoline and diesel between 2019 and 2025 is forecast to weaken as countries around the world implement policies to improve efficiency and cut carbon dioxide emissions – and as solar power becomes the cheapest electricity in many markets and electric vehicles increase in popularity. The impact of energy transitions on oil supply remains unclear, with many companies prioritising short-cycle projects for the coming years.

“The coronavirus crisis is adding to the uncertainties the global oil industry faces as it contemplates new investments and business strategies,” Dr Birol said. “The pressures on companies are changing, with European oil majors turning electric to diversify. They need to show that they can deliver not just the energy that economies rely on, but also the emissions reductions that the world needs to help tackle our climate challenge.”

Alberta Electricity Demand Record surges during a deep freeze, as AESO reports peak load in megawatts and ENMAX notes increased usage in Calgary and Edmonton, with thermostats up amid a cold snap straining power grid.

Key Points

It is the highest electricity peak load recorded by AESO, reflecting maximum grid usage during cold snaps.

✅ AESO reported 11,729 MW peak during the deep freeze

✅ ENMAX saw a 13 percent demand jump week over week

✅ Cold snap drove thermostats up in Calgary and Edmonton

Albertans are cranking up their thermostats and blasting heat into their homes at overwhelmingly high rates as the deep freeze continues across the region. 

It’s so cold that the province set a new all-time record Tuesday evening for electricity usage. 

According to the Alberta Electric System Operator (AESO), as electricity prices spike in Alberta during extreme demand, 11,729 MW of power was used around 7 p.m. Tuesday, passing the previous record set in January of last year by 31 MW.

Temperatures reached a low of -29 C in Calgary, where rising electricity bills have strained budgets, on Tuesday while Edmonton saw a low of -30 C, according to Environment Canada. Wind chill  made it feel closer to -40.

“That increase — 31 Megawatts — is sizeable and about the equivalent of a moderately sized generation facility,” said AESO communications director, Mike Deising. 

“We do see higher demand in winter because it’s cold and it’s dark and that’s really exactly what we’re seeing right now as demand goes up, people turn on their lights and turn up their furnaces,” and with the UCP scrapping the price cap earlier that’s really exactly what we’re seeing right now as demand goes up, people turn on their lights and turn up their furnaces.”

Deising adds Alberta’s electricity usage over the last year has actually been much lower than average, though experts urge Albertans to lock in rates amid expected volatility, despite more people staying home during the pandemic. 

That trend was continuing into 2021, but as Alberta's rising electricity prices draw attention, it’s expected that more records could be broken. 

“If the cold snap continues we may likely set another record (Wednesday) or (Thursday), depending on what happens with the temperatures,” he said. 

Meanwhile, ENMAX has reported an average real-time system demand of 1,400 MW for the city of Calgary. 

That amount is still a far cry from the current season record of 1,619 MW (Aug. 18, 2020), the all-time winter record of 1,653MW (Dec. 2, 2013), and the all-time summer record of 1,692 MW (Aug. 10, 2018). 

ENMAX says electricity demand has increased quite significantly over the past week — by about 13 per cent — since the cold snap set in. 

As a result, the energy company is once again rolling out its ‘Winter Wise’ campaign in an effort to encourage Calgarians to manage both electricity and natural gas use in the winter, even as a consumer price cap on power bills is enabled by new legislation.

Manitoba Hydro Interim Rate Increase faces PUB scrutiny as consumers coalition challenges a 5% electricity rate hike, citing drought planning, retained earnings, affordability, transparency, and impacts on fixed incomes and northern communities.

Key Points

A proposed 5% electricity rate hike under PUB review, opposed by consumers citing drought planning and affordability.

✅ Coalition backs 2% hike; 5% seen as undue burden

✅ PUB review sought; interim process lacks transparency

✅ Retained earnings, efficiencies cited to offset drought

The Consumers Coalition is urging the Public Utilities Board (PUB) to reject Manitoba Hydro’s current interim rate increase application, amid ongoing debates about Hydro governance and policy.

Hydro is requesting a five per cent jump in electricity rates starting on January 1, claiming drought conditions warrant the increase but the coalition disagrees, saying a two per cent increase would be sufficient.

The coalition, which includes Harvest Manitoba, the Consumers’ Association of Canada-Manitoba, and the Aboriginal Council of Winnipeg, said a 5 per cent rate increase would put an unnecessary strain on consumer budgets, especially for those on fixed incomes or living up north.

"We feel that, in many ways, Manitobans have already paid for this drought," said Gloria Desorcy, executive director of the Consumers’ Association of Canada - Manitoba.

The coalition argues that hydroelectric companies already plan for droughts and that hydro should be using past earnings to mitigate any losses.

The group claims drought conditions would have added about 0.8 per cent to Hydro’s bottom line. They said remaining revenues from a two per cent increase could then be used to offset the increased costs of major projects like the Keeyask generating station and service its growing debt obligations.

The group also said Hydro is financially secure and is projecting a positive net income of $112 million next year without rate increases, even as utility profits can swing with market conditions, assuming the drought doesn’t continue.

They argue Hydro can use retained earnings as a tool to mitigate losses, rather than relying on deferral accounting that shifts costs, and find further efficiencies within the corporation.

"So we said two per cent, which is much more palatable for consumers especially at the time when so many consumers are struggling with so many higher bills,” said Desorcy.

According to the coalition’s calculations, that works out to a $2-4 increase per month, and debates such as ending off-peak pricing in Ontario show how design affects bills, depending on whether electricity is used for heating, but it could be higher.

The coalition said their proposed two per cent rate increase should be applied to all Manitoba Hydro customers and have a set expiration date of January 1, 2023.

Another issue, according to the coalition, is the process of an interim rate application does not provide any meaningful transparency and accountability, whereas recent OEB decisions in Ontario have outlined more robust public processes.

Desorcy said the next step is up to the PUB, though board upheaval at Hydro One in Ontario shows how governance shifts can influence outcomes.

The board is expected to decide on the proposed increase in the next couple of weeks.

Smart EV Charging orchestrates vehicle-to-grid (V2G), demand response, and fast charging to balance the power grid, integrating renewables, electrolyzers for hydrogen, and megawatt chargers for fleets with advanced control and co-optimization.

Key Points

Smart EV charging coordinates EV load to stabilize the grid, cut peaks, and integrate renewable energy efficiently.

✅ Reduces peak demand via coordinated, flexible load control

✅ Enables V2G services with renewables and battery storage

✅ Supports megawatt fast charging for heavy-duty fleets

As electric vehicle (EV) sales continue to rev up in the United States, the power grid is in parallel contending with the greatest transformation in its 100-year history: the large-scale integration of renewable energy and power electronic devices. The expected expansion of EVs will shift those challenges into high gear, causing cities to face gigawatt-growth in electricity demand, as analyses of EV grid impacts indicate, and higher amounts of variable energy.

Coordinating large numbers of EVs with the power system presents a highly complex challenge. EVs introduce variable electrical loads that are highly dependent on customer behavior. Electrified transportation involves co-optimization with other energy systems, like natural gas and bulk battery storage, including mobile energy storage flexibility for new operational options. It could involve fleets of automated ride-hailing EVs and lead to hybrid-energy truck stops that provide hydrogen and fast-charging to heavy-duty vehicles.

Those changes will all test the limits of grid integration, but the National Renewable Energy Laboratory (NREL) sees opportunity at the intersection of energy systems and transportation. With powerful resources for simulating and evaluating complex systems, several NREL projects are determining the coordination required for fast charging, balancing electrical supply and demand, and efficient use of all energy assets.

Smart and Not-So-Smart Control
To appreciate the value of coordinated EV charging, it is helpful to imagine the opposite scenario.

"Our first question is how much benefit or burden the super simple, uncoordinated approach to electric vehicle charging offers the grid," said Andrew Meintz, the researcher leading NREL's Electric Vehicle Grid Integration team, as well as the RECHARGE project for smart EV charging. "Then we compare that to the 'whiz-bang,' everything-is-connected approach. We want to know the difference in value."

In the "super simple" approach, Meintz explained that battery-powered electric vehicles grow in market share, exemplified by mass-market EVs, without any evolution in vehicle charging coordination. Picture every employee at your workplace driving home at 5 p.m. and charging their vehicle. That is the grid's equivalent of going 0 to 100 mph, and if it does not wreck the system, it is at least very expensive. According to NREL's Electrification Futures Study, a comprehensive analysis of the impacts of widespread electrification across all U.S. economic sectors, in 2050 EVs could contribute to a 33% increase in energy use during peak electrical demand, underscoring state grid challenges that make these intervals costly when energy reserves are procured. In duck curve parlance, EVs will further strain the duck's neck.

Meintz's "whiz-bang" approach instead imagines EV control strategies that are deliberate and serve to smooth, rather than intensify, the upcoming demand for electricity. It means managing both when and where vehicles charge to create flexible load on the grid.

At NREL, smart strategies to dispatch vehicles for optimal charging are being developed for both the grid edge, where consumers and energy users connect to the grid, as in RECHARGEPDF, and the entire distribution system, as in the GEMINI-XFC projectPDF. Both projects, funded by the U.S. Department of Energy's (DOE's) Vehicle Technologies Office, lean on advanced capabilities at NREL's Energy Systems Integration Facility to simulate future energy systems.

At the grid edge, EVs can be co-optimized with distributed energy resources—small-scale generation or storage technologies—the subject of a partnership with Eaton that brought industry perspectives to bear on coordinated management of EV fleets.

At the larger-system level, the GEMINI-XFC project has extended EV optimization scenarios to the city scale—the San Francisco Bay Area, to be specific.

"GEMINI-XFC involves the highest-ever-fidelity modeling of transportation and the grid," said NREL Research Manager of Grid-Connected Energy Systems Bryan Palmintier.

"We're combining future transportation scenarios with a large metro area co-simulationPDF—millions of simulated customers and a realistic distribution system model—to find the best approaches to vehicles helping the grid."

GEMINI-XFC and RECHARGE can foresee future electrification scenarios and then insert controls that reduce grid congestion or offset peak demand, for example. Charging EVs involves a sort of shell game, where loads are continually moved among charging stations to accommodate grid demand.

But for heavy-duty vehicles, the load is harder to hide. Electrified truck fleets will hit the road soon, creating power needs for electric truck fleets that translate to megawatts of localized demand. No amount of rerouting can avoid the requirements of charging heavy-duty vehicles or other instances of extreme fast-charging (XFC). To address this challenge, NREL is working with industry and other national laboratories to study and demonstrate the technological buildout necessary to achieve 1+ MW charging stationsPDF that are capable of fast charging at very high energy levels for medium- and heavy-duty vehicles.

To reach such a scale, NREL is also considering new power conversion hardware based on advanced materials like wide-bandgap semiconductors, as well as new controllers and algorithms that are uniquely suited for fleets of charge-hungry vehicles. The challenge to integrate 1+ MW charging is also pushing NREL research to higher power: Upcoming capabilities will look at many-megawatt systems that tie in the support of other energy sectors.

Renewable In-Roads for Hydrogen

At NREL, the drive toward larger charging demands is being met with larger research capabilities. The announcement of ARIES opens the door to energy systems integration research at a scale 10-times greater than current capabilities: 20 MW, up from 2 MW. Critically, it presents an opportunity to understand how mobility with high energy demands can be co-optimized with other utility-scale assets to benefit grid stability.

"If you've got a grid humming along with a steady load, then a truck requires 500 kW or more of power, it could create a large disruption for the grid," said Keith Wipke, the laboratory program manager for fuel cells and hydrogen technologies at NREL.

Such a high power demand could be partially served by battery storage systems. Or it could be hidden entirely with hydrogen production. Wipke's program, with support from the DOE's Hydrogen and Fuel Cell Technologies Office, has been performing studies into how electrolyzers—devices that use electricity to break water into hydrogen and oxygen—could offset the grid impacts of XFC. These efforts are also closely aligned with DOE's H2@Scale vision for affordable and effective hydrogen use across multiple sectors, including heavy-duty transportation, power generation, and metals manufacturing, among others.

"We're simulating electrolyzers that can match the charging load of heavy-duty battery electric vehicles. When fast charging begins, the electrolyzers are ramped down. When fast charging ends, the electrolyzers are ramped back up," Wipke said. "If done smoothly, the utility doesn't even know it's happening."

NREL Researchers Rishabh Jain, Kazunori Nagasawa, and Jen Kurtz are working on how grid integration of electrolyzers—devices that use electricity to break water into hydrogen and oxygen—could offset the grid impacts of extreme fast-charging. Credit: National Renewable Energy Laboratory
As electrolyzers harness the cheap electrons from off-demand periods, a significant amount of hydrogen can be produced on site. That creates a natural energy pathway from discount electricity into a fuel. It is no wonder, then, that several well-known transportation and fuel companies have recently initiated a multimillion-dollar partnership with NREL to advance heavy-duty hydrogen vehicle technologies.

"The logistics of expanding electric charging infrastructure from 50 kW for a single demonstration battery electric truck to 5,000 kW for a fleet of 100 could present challenges," Wipke said. "Hydrogen scales very nicely; you're basically bringing hydrogen to a fueling station or producing it on site, but either way the hydrogen fueling events are decoupled in time from hydrogen production, providing benefits to the grid."

The long driving range and fast refuel times—including a DOE target of achieving 10-minutes refuel for a truck—have already made hydrogen the standout solution for applications in warehouse forklifts. Further, NREL is finding that distributed electrolyzers can simultaneously produce hydrogen and improve voltage conditions, which can add much-needed stability to a grid that is accommodating more energy from variable resources.

Those examples that co-optimize mobility with the grid, using diverse technologies, are encouraging NREL and its partners to pursue a new scale of systems integration. Several forward-thinking projects are reimagining urban mobility as a mix of energy solutions that integrate the relative strengths of transportation technologies, which complement each other to fill important gaps in grid reliability.

The Future of Urban Mobility
What will electrified transportation look like at high penetrations? A few NREL projects offer some perspective. Among the most experimental, NREL is helping the city of Denver develop a smart community, integrated with electrified mobility and featuring automated charging and vehicle dispatch.

On another path to advanced mobility, Los Angeles has embarked on a plan to modernize its electricity system infrastructure, reflecting California EV grid stability goals—aiming for a 100% renewable energy supply by 2045, along with aggressive electrification targets for buildings and vehicles. Through the Los Angeles 100% Renewable Energy Study, the city is currently working with NREL to assess the full-scale impacts of the transition in a detailed analysis that integrates diverse capabilities across the laboratory.

The transition would include the Port of Long Beach, the busiest container port in the United States.

At the port, NREL is applying the same sort of scenario forecasting and controls evaluation as other projects, in order to find the optimal mix of technologies that can be integrated for both grid stability and a reliable quality of service: a mix of hydrogen fuel-cell and battery EVs, battery storage systems, on-site renewable generation, and extreme coordination among everything.

"Hydrogen at ports makes sense for the same reason as trucks: Marine applications have big power and energy demands," Wipke said. "But it's really the synergies between diverse technologies—the existing infrastructure for EVs and the flexibility of bulk battery systems—that will truly make the transition to high renewable energy possible."

Like the Port of Long Beach, transportation hubs across the nation are adapting to a complex environment of new mobility solutions. Airports and public transit stations involve the movement of passengers, goods, and services at a volume exceeding anywhere else. With the transition to digitally connected electric mobility changing how airports plan for the future, NREL projects such as Athena are using the power of high-performance computing to demonstrate how these hubs can maximize the value of passenger and freight mobility per unit of energy, time, and/or cost.

The growth in complexity for transportation hubs has just begun, however. Looking ahead, fleets of ride-sharing EVs, automated vehicles, and automated ride-sharing EV fleets could present the largest effort to manage mobility yet.

A Self-Driving Power Grid
To understand the full impact of future mobility-service providers, NREL developed the HIVE (Highly Integrated Vehicle Ecosystem) simulation framework. HIVE combines factors related to serving mobility needs and grid operations—such as a customer's willingness to carpool or delay travel, and potentially time-variable costs of recharging—and simulates the outcome in an integrated environment.

"Our question is, how do you optimize the management of a fleet whose primary purpose is to provide rides and improve that fleet's dispatch and charging?" said Eric Wood, an NREL vehicle systems engineer.

HIVE was developed as part of NREL's Autonomous Energy Systems research to optimize the control of automated vehicle fleets. That is, optimized routing and dispatch of automated electric vehicles.

The project imagines how price signals could influence dispatch algorithms. Consider one customer booking a commute through a ride-hailing app. Out of the fleet of vehicles nearby—variously charged and continually changing locations—which one should pick up the customer?

Now consider the movements of thousands of passengers in a city and thousands of vehicles providing transportation services. Among the number of agents, the moment-to-moment change in energy supply and demand, and the broad diversity in vendor technologies, "we're playing with a lot of parameters," Wood said.

But cutting through all the complexity, and in the midst of massive simulations, the end goal for vehicle-to-grid integration is consistent:

"The motivation for our work is that there are forecasts for significant load on the grid from the electrification of transportation," Wood said. "We want to ensure that this load is safely and effectively integrated, while meeting the expectations and needs of passengers."

True Replacement without Caveats

Electric vehicles are not necessarily helpful to the grid, but they can be. As EVs become established in the transportation sector, NREL is studying how to even out any bumps that electrified mobility could cause on the grid and advance any benefits to commuters or industry.

"It all comes down to load flexibility," Meintz said. "We're trying to decide how to optimally dispatch vehicle charging to meet quality-of-service considerations, while also minimizing charging costs."
