Hourly Electricity Emissions Tracking maps grid balancing areas, embodied emissions, and imports/exports, revealing carbon intensity shifts across PJM, ERCOT, and California ISO, and clarifying renewable energy versus coal impacts on health and climate.

Key Points

An hourly method tracing generation, flows, and embodied emissions to quantify carbon intensity across US balancing areas.

✅ Hourly traces of imports/exports and generation mix

✅ Consumption-based carbon intensity by balancing area

✅ Policy insights for renewables, coal, health costs

In the United States, electricity generation accounts for nearly 30% of our carbon emissions. Some states have responded to that by setting aggressive renewable energy standards; others are hoping to see coal propped up even as its economics get worse. Complicating matters further is the fact that many regional grids are integrated, and as America goes electric the stakes grow, meaning power generated in one location may be exported and used in a different state entirely.

Tracking these electricity exports is critical for understanding how to lower our national carbon emissions. In addition, power from a dirty source like coal has health and environment impacts where it's produced, and the costs of these aren't always paid by the parties using the electricity. Unfortunately, getting reliable figures on how electricity is produced and where it's used is challenging, even for consumers trying to find where their electricity comes from in the first place, leaving some of the best estimates with a time resolution of only a month.

Now, three Stanford researchers—Jacques A. de Chalendar, John Taggart, and Sally M. Benson—have greatly improved on that standard, and they have managed to track power generation and use on an hourly basis. The researchers found that, of the 66 grid balancing areas within the United States, only three have carbon emissions equivalent to our national average, and they have found that imports and exports of electricity have both seasonal and daily changes. de Chalendar et al. discovered that the net results can be substantial, with imported electricity increasing California's emissions/power by 20%.

Hour by hour
To figure out the US energy trading landscape, the researchers obtained 2016 data for grid features called balancing areas. The continental US has 66 of these, providing much better spatial resolution on the data than the larger grid subdivisions. This doesn't cover everything—several balancing areas in Canada and Mexico are tied in to the US grid—and some of these balancing areas are much larger than others. The PJM grid, serving Pennsylvania, New Jersey, and Maryland, for example, is more than twice as large as Texas' ERCOT, in a state that produces and consumes the most electricity in the US.

Despite these limitations, it's possible to get hourly figures on how much electricity was generated, what was used to produce it, and whether it was used locally or exported to another balancing area. Information on the generating sources allowed the researchers to attach an emissions figure to each unit of electricity produced. Coal, for example, produces double the emissions of natural gas, which in turn produces more than an order of magnitude more carbon dioxide than the manufacturing of solar, wind, or hydro facilities. These figures were turned into what the authors call "embodied emissions" that can be traced to where they're eventually used.

Similar figures were also generated for sulfur dioxide and nitrogen oxides. Released by the burning of fossil fuels, these can both influence the global climate and produce local health problems.

Huge variation
The results were striking. "The consumption-based carbon intensity of electricity varies by almost an order of magnitude across the different regions in the US electricity system," the authors conclude. The low is the Bonneville Power grid region, which is largely supplied by hydropower; it has typical emissions below 100kg of carbon dioxide per megawatt-hour. The highest emissions come in the Ohio Valley Electric region, where emissions clear 900kg/MW-hr. Only three regional grids match the overall grid emissions intensity, although that includes the very large PJM (where capacity auction payouts recently fell), ERCOT, and Southern Co balancing areas.

Most of the low-emissions power that's exported comes from the Pacific Northwest's abundant hydropower, while the Rocky Mountains area exports electricity with the highest associated emissions. That leads to some striking asymmetries. Local generation in the hydro-rich Idaho Power Company has embodied emissions of only 71kg/MW-hr, while its imports, coming primarily from Rocky Mountain states, have a carbon content of 625kg/MW-hr.

The reliance on hydropower also makes the asymmetry seasonal. Local generation is highest in the spring as snow melts, but imports become a larger source outside this time of year. As solar and wind can also have pronounced seasonal shifts, similar changes will likely be seen as these become larger contributors to many of these regional grids. Similar things occur daily, as both demand and solar production (and, to a lesser extent, wind) have distinct daily profiles.

The Golden State
California's CISO provides another instructive case. Imports represent less than 30% of its total electric use in 2016, yet California electricity imports provided 40% of its embodied emissions. Some of these, however, come internally from California, provided by the Los Angeles Department of Water and Power. The state itself, however, has only had limited tracking of imported emissions, lumping many of its sources as "other," and has been exporting its energy policies to Western states in ways that shape regional markets.

Overall, the 2016 inventory provides a narrow picture of the US grid, as plenty of trends are rapidly changing our country's emissions profile, including the rise of renewables and the widespread adoption of efficiency measures and other utility trends in 2017 that continue to evolve. The method developed here can, however, allow for annual updates, providing us with a much better picture of trends. That could be quite valuable to track things like how the rapid rise in solar power is altering the daily production of clean power.

More significantly, it provides a basis for more informed policymaking. States that wish to promote low-emissions power can use the information here to either alter the source of their imports or to encourage the sites where they're produced to adopt more renewable power. And those states that are exporting electricity produced primarily through fossil fuels could ensure that the locations where the power is used pay a price that includes the health costs of its production.

BC-Alberta Transmission Intertie enables clean hydro to balance wind and solar, expanding transmission capacity so Site C hydro can dispatch power, cut emissions, lower costs, and accelerate electrification across provincial grids under federal climate policy.

Key Points

A cross-provincial grid link using BC hydro to firm Alberta wind and solar, cutting emissions and costs.

✅ Balances variable renewables with dispatchable hydro from Site C.

✅ Enables power trade: peak exports, low-cost wind imports.

✅ Lowers decarbonization costs and supports electrification goals.

By Mark Jaccard

Lost in the news and noise of the federal government's newly announced $170-per-tonne carbon tax was a single, critical sentence in Canada's updated climate plan, one that signals a strategy that could serve as the cornerstone for a future free of greenhouse gas emissions.

"The government will work with provinces and territories to connect parts of Canada that have abundant clean hydroelectricity with parts that are currently more dependent on fossil fuels for electricity generation — including by advancing strategic intertie projects."

Why do we think this one sentence is so important? And what has it got to do with the controversial Site C project Site C electricity debate under construction in British Columbia?

The answer lies in the huge amount of electricity we'll need to generate in Canada to achieve our climate goals for 2030 and 2050. Even while we aggressively pursue energy efficiency, our electric cars, buses and perhaps trucks in Canada's net-zero race will need a huge amount of new electricity, as will our buildings and industries. 

Luckily, Canada is blessed with an electricity system that is the envy of the world — already over 80 per cent zero emission, the bulk being from flexible hydro-electricity, with a backbone of nuclear power largely in Ontario, a national electricity success and rapidly growing shares of cheap wind and solar. 

Provincial differences
Yet the story differs significantly from one province to another. While B.C.'s electricity is nearly emissions free, the opposite is true of its neighbour, Alberta, where more than 80 per cent still comes from fossil fuels. This, despite an impressive shift away from coal power in recent years.

Now imagine if B.C. and Alberta were one province.

This might sound like the start of a bad joke, or a horror movie to some, but it's the crux of new research by a trio of energy economists who put a fine point on the value of such co-operation.

The study, by Brett Dolter, Kent Fellows and Nic Rivers, takes a detailed look at the economic case for completing Site C, BC Hydro's controversial large hydro project under construction, and makes three key conclusions.

First, they argue Site C should likely not have been started in the first place. Only a narrow set of assumptions can now justify its total cost. But what's done is done, and absent a time machine, the decision to complete the dam rests on go-forward costs.

On that note, their second conclusion is no more optimistic. Considering the cost to complete the project, even accounting for avoiding termination costs should it be cancelled, they find the economics of completing Site C over-budget status to be weak. If the New York Times had a Site C needle in the style of the newspaper's election visual, it would be "leaning cancel" at this point.

But it is their third conclusion that stands out as worthy of attention. They argue there is a case for completing Site C if the following conditions are met:

B.C. and Alberta reduce their electricity sector emissions by more than 75 per cent (this really means Alberta, given B.C.'s already clean position); and

B.C. and Alberta expand their ability to move electricity between their respective provinces by building new transmission lines.

Let's deal with each of these in turn.

On Condition 1, we give an emphatic: YES! Reducing electricity emissions is an absolute must to meet climate pledges if Canada is to come even close to achieving its net-zero goals. As noted above, a clean electricity grid will be the cornerstone of a decarbonized economy as we generate a great deal more power to electrify everything from industrial processes to heating to transportation and more. 

Condition 2 is more challenging. Talk of increasing transmission connections across Canada, including Hydro-Québec's U.S. strategy has been ongoing for over 50 years, with little success to speak of. But this time might well be different. And the implications for a completed Site C, should the government go that route, are profound.

Wind and solar costs rapidly declining
Somewhat ironically, the case for Site C is made stronger by the rapidly declining costs of two of its apparent renewable competitors: wind and solar.

The cost of wind and solar generation has fallen by 70 per cent and 90 per cent, respectively, a dramatic decline in the past 10 years. No longer can these variable sources of power be derided as high cost; they are unequivocally the cheapest sources of raw energy in electricity systems today.

However, electricity system operators must deal with their "non-dispatchability," a seemingly complicated term that simply means they produce electricity only when the sun shines and the wind blows, which is not necessarily when electricity customers want their electricity delivered (dispatched) to them. And because of this characteristic, the value of dispatchable electricity sources, like a completed Site C, will grow as a complement to wind and solar. 

Thus, as Alberta's generation of cheap wind and solar grows, so too does the value of connecting it with the firm, dispatchable resources available in B.C.

Rather than displacing wind and solar, large hydro facilities with the ability to increase or decrease output on short notice can actually enable more investment in these renewable sources. Expanding the transmission connection, with Site C on one side of that line, becomes even more valuable.

Many in B.C. might read this and rightly ask themselves, why should we foot the bill for this costly project to help out Albertans? The answer is that it won't be charity — B.C. will get paid handsomely for the power it delivers in peak periods and will be able to import wind power at low prices from Alberta in other times. B.C. will benefit greatly from these gains of trade.

Turning to Alberta, why should Albertans support B.C. reaping these gains? The answer is two-fold.

First, Site C will actually enable more low-cost wind and solar to be built in Alberta due to hydro's ability to balance these non-dispatchable renewables. Jobs and economic opportunity will occur in Alberta from this renewable energy growth.

Second, while B.C. imports won't come cheap, they will be less costly than the decarbonization alternatives Alberta would need without B.C.'s flexible hydro, as the economists' study shows. This means lower overall costs to Alberta's power consumers.

A clear role for Ottawa
To be sure, there are challenges to increasing the connectedness of B.C. and Alberta's power systems, not least of which is BC Hydro being a regulated, government-owned monopoly while Alberta is a competitive market amongst private generators. Some significant accommodations in climate policy and grids will be needed to ensure both sides can compete and benefit from trade on an equal footing.

There is also the pesky matter of permitting and constructing thousands of kilometres of power lines. Getting linear energy infrastructure built in Canada has not exactly been our forte of late.

We are not naive to the significant challenges in such an approach, but it's not often that we see such a clear narrative for beneficial climate action that, when considered at the provincial level, is likely to be thwarted, but when considered more broadly can produce a big win.

It's the clearest example yet of a role for the federal government to bridge the gap, to facilitate the needed regulatory conversations, and, let's be frank, to bring money to the table to make the line happen. Neither provincial side is likely to do it on their own, nor, as history has shown, are they likely to do it together. 

For a government committed to reducing emissions, and with a justified emphasis on the electricity sector, the opportunity to expand the Alberta-B.C. transmission intertie, leveraging the flexibility of B.C.'s hydro with the abundance of wind and solar potential on the Prairies, offers a potential massive decarbonization win for Western Canada that is too good to ignore.

Canada Net-Zero Grid Lessons highlight Europe's energy transition risks: Germany's power prices, wind and solar variability, nuclear phaseout, grid reliability, storage, market design, policy reforms, and distributed energy resources for resilient decarbonization.

Key Points

Lessons stress an all-of-the-above mix, robust market design, storage, and nuclear to ensure reliability, affordability.

✅ Diversify: nuclear, hydro, wind, solar, storage for reliability.

✅ Reform markets and grid planning for integration and flexibility.

✅ Build fast: streamline permitting, invest in transmission and DERs.

Europe is currently suffering the consequences of an uncoordinated rush to carbon-free electricity that experts warn could hit Canada as well unless urgent action is taken.

Power prices in Germany, for example, hit a record 91 euros ($135 CAD) per megawatt-hour earlier this month. That is more than triple what electricity costs in Ontario, where greening the grid could require massive investment, even during periods of peak demand.

Experts blame the price spikes in large part on a chaotic transition to a specific set of renewable electricity sources - wind and solar - at the expense of other carbon-free supplies such as nuclear power. Germany, Europe’s largest economy, plans to close its last remaining nuclear power plant next year despite warnings that renewables are not being added to the German grid quickly enough to replace that lost supply.

As Canada prepares to transition its own electricity grid to 100 per cent net-zero supplies by 2035, with provinces like Ontario planning new wind and solar procurement, experts say the European power crisis offers lessons this country must heed in order to avoid a similar fate.

'A CAUTIONARY TALE'
“Some countries have rushed their transition without thinking about what people need and when they need it,” said Chris Bentley, managing director of Ryerson University’s Legal Innovation Zone who also served as Ontario’s Minister of Energy from 2011 to 2013, in an interview. “Germany has experienced a little bit of this issue recently when the wind wasn’t blowing.”

Wind power usually provides between 20 and 30 per cent of Germany’s electricity needs, but the below-average breeze across much of continental Europe in recent months has pushed that figure down.

“There is a cautionary tale from the experience in Europe,” said Francis Bradley, chief executive officer of the Canadian Electricity Association, in an interview. “There was also a cautionary tale from what took place this past winter in Texas,” he added, referring to widespread power failures in Texas spawned by a lack of backup power supplies during an unusually cold winter that led to many deaths.

The first lesson Canada must learn from those cautionary tales, Bradley said, “is the need to pursue an all-of-the-above approach.”

“It is absolutely essential that every opportunity and every potential technology for low-carbon or no-carbon electricity needs to be pursued and needs to be pursued to the fullest,” he said.

The more important lesson for Canada, according to Binnu Jeyakumar, is about the need for a more holistic, nuanced approach to our own net-zero transition.

“It is very easy to have runaway narratives that just pinpoint the blame on one or two issues, but the lesson here isn’t really about the reliability of renewables as there are failures that occur across all sources of electricity supply,” said Jeyakumar, director of clean energy for the Pembina Institute, in an interview. 

“The takeaway for us is that we need to get better at learning how to integrate an increasingly diverse electricity grid,” she said. “It is not necessarily the technologies themselves, it is about how we do grid planning, how are our markets structured and are we adapting them to the trends that are evolving in the electricity and energy sectors.”
 

'ABSOLUTELY ENORMOUS' CHALLENGE IS 'ALMOST MIND-BENDING'
Canada already gets the vast majority of its electricity from emission-free sources. Hydro provides roughly 60 per cent of our power, nuclear contributes another 15 per cent and renewables such as wind and solar contribute roughly seven per cent more, according to federal government data.

Tempting as it might be to view the remaining 18 per cent of Canadian electricity that is supplied by oil, natural gas and coal as a small enough proportion that it should be relatively easy to replace, with some analyses warning that scrapping coal abruptly can be costly for consumers, the reality is much more difficult.

“It is the law of diminishing returns or the 80-20 rule where the first 80 per cent is easy but the last 20 per cent is hard,” Bradley explained. “We already have an electricity sector that is 80 per cent GHG-free, so getting rid of that last 20 per cent is the really difficult part because the low-hanging fruit has already been picked.”

Key to successfully decarbonizing Canada’s power grid will be the recognition that electricity demand is constantly growing, a point reinforced by a recent power challenges report that underscores the scale. That means Canada needs to build out enough emission-free power sources to replace existing fossil fuel-based supplies while also ensuring adequate supplies for future demand.

“It is one thing to say that by 2035 we are going to have a decarbonized electricity system, but the challenge really is the amount of additional electricity that we are going to need between now and 2035,” said John Gorman, chief executive officer of the Canadian Nuclear Association, which has argued that nuclear is key to climate goals in Canada, and former CEO of the Canadian Solar Industries Association, in an interview. “It is absolutely enormous, I mean, it is almost mind-bending.”

Canada will need to triple the amount of electricity produced nationwide by 2050, according to a report from SNC-Lavalin published earlier this year, and provinces such as Ontario face a shortfall over the next few years, Gorman said. Gorman said that will require adding between five and seven gigawatts of new installed capacity to Canada’s electricity grid every year from 2021 through 2050 or more than twice the amount of new power supply Canada brings online annually right now.

For perspective, consider Ontario’s Bruce Power nuclear facility. It took 27 years to bring that plant to its current 6.4 gigawatt (GW) capacity, but meeting Canada’s decarbonization goals will require adding roughly the equivalent capacity of Bruce Power every year for the next three decades.

“The task of creating enough electricity in the coming years is truly enormous and governments have not really wrapped their heads around that yet,” Gorman said. “For those of us in the energy sector, it is the type of thing that can keep you up at night.”

GOVERNMENT POLICY 'HELD HOSTAGE' BY 'DINOSAURS'
The Pembina Institute’s Jeyakumar agreed “the last mile is often the most difficult” and will require “a concerted effort both at the federal level and the provincial level.”

Governments will “need to be able to support innovation and solutions such as non-wires alternatives,” she said. “Instead of building a massive new transmission line or beefing up an old one, you could put a storage facility at the end of an existing line. Distributed energy resources provide those kinds of non-wires alternatives and they are already cost-effective and competitive with oil and gas.”

For Glen Murray, who served as Ontario’s minister of infrastructure and transportation from early 2013 to mid-2014 before assuming the environment and climate change portfolio until his resignation in mid-2017, that is a key lesson governments have yet to learn.

“We are moving away from a centralized distribution model to distributed systems where individual buildings and homes and communities will supply their own electricity needs,” said Murray, who currently works for an urban planning software company in Winnipeg, in an interview. “Yet both the federal and provincial governments are assuming that we are going to continue to have large, centralized generation of power, but that is simply not going to be the case.”

“Government policy is not focused on driving that because they are held hostage by their own hydro utilities and the big gas companies,” Murray said. “They are controlling the agenda even though they are the dinosaurs.”

Referencing the SNC-Lavalin report, Gorman noted as many as 45 small, modular nuclear reactors as well as 20 conventional nuclear power plants will be required in the coming decades, with jurisdictions like Ontario exploring new large-scale nuclear as part of that mix: “And that is in the context of also maximizing all the other emission-free electricity sources we have available as well from wind to solar to hydro and marine renewables,” Gorman said, echoing the “all-of-the-above” mindset of the Canadian Electricity Association.

There are, however, “fundamental rules of the market and the regulatory system that make it an uneven playing field for these new technologies to compete,” said Jeyakumar, agreeing with Murray’s concerns. “These are all solvable problems but we need to work on them now.”
 

'2035 IS TOMORROW'
According to Bentley, the former Ontario energy minister-turned academic, “the government's role is to match the aspiration with the means to achieve that aspiration.”

“We have spent far more time as governments talking about the goals and the high-level promises [of a net-zero electricity grid by 2035] without spending as much time as we need to in order to recognize what a massive transformation this will mean,” Bentley said. “It is easy to talk about the end-goal, but how do you get there?”

The Canadian Electricity Assocation’s Bradley agreed “there are still a lot of outstanding questions about how we are going to turn those aspirations into actual policies. The 2035 goal is going to be very difficult to achieve in the absence of seeing exactly what the policies are that are going to move us in that direction.”

“It can take a decade to go through the processes of consultations and planning and then building and getting online,” Bradley said. “Particularly when you’re talking about big electricity projects, 2035 is tomorrow.”

Jeyakumar said “we cannot afford to wait any longer” for policies to be put in place as the decisions governments make today “will then lock us in for the next 30 or 40 years into specific technologies.”

“We need to consider it like saving for retirement,” said Gorman of the Canadian Nuclear Association. “Every year that you don’t contribute to your retirement savings just pushes your retirement one more year into the future.”

Eletrobras Privatization Strike sparks a 72-hour CNE walkout by Brazil's electricity workers, opposing asset sell-offs and grid privatization while pledging essential services; unions target President Wilson Ferreira Jr. over energy-sector reforms.

Key Points

A 72-hour CNE walkout by Brazil's electricity workers opposing Eletrobras sell-offs, while keeping essential services.

✅ 72-hour strike led by CNE unions and federations

✅ Targets privatization plans and leadership at Eletrobras

✅ Essential services maintained to avoid consumer impact

Brazil's national electricity workers' collective (CNE) has called for a 72-hour strike to protest the privatization of state-run electric company Eletrobras and its subsidiaries.

The CNE, which gathers the electricity workers' confederation, federations, unions and associations, said the strike is to begin at Monday midnight (0300 GMT) and last through midnight Wednesday, even as some utilities elsewhere have considered asking staff to live on site to maintain operations.

Workers are demanding the ouster of Eletrobras President Wilson Ferreira Jr., who they say is the leading promoter of the privatization move.

Some 24,000 workers are expected to take part in the strike. However, the CNE said it will not affect consumers by ensuring essential services, a pledge echoed by utilities managing costs elsewhere such as Manitoba Hydro's unpaid days off during the pandemic.

#google#

Eletrobras accounts for 32 percent of Brazil's installed energy generation capacity, mainly via hydroelectric plants. Besides, it also operates nuclear and thermonuclear plants, and solar and wind farms, reflecting trends captured by young Canadians' interest in electricity jobs in recent years.

The company distributes electricity in six northern and northeastern states, and handles 47 percent of the nation's electricity transmission lines, even as a U.S. grid pandemic warning has highlighted reliability risks.

The government owns a 63-percent stake in the company, a reminder that public policy shapes the sector, similar to Canada's future-of-work investment initiatives announced recently.

Calistoga Resiliency Centre Microgrid delivers grid resilience via green hydrogen and BESS, providing island-mode backup during PSPS events, wildfire risk, and outages, with black-start and grid-forming capabilities for reliable community power.

Key Points

A hybrid green hydrogen and BESS facility ensuring resilient, islanded power for Calistoga during PSPS and outages.

✅ 293 MWh capacity with 8.5 MW peak for critical backup

✅ Hybrid lithium-ion BESS plus green hydrogen fuel cells

✅ Island mode with black-start and grid-forming support

Energy Vault, a prominent energy storage and technology company known for its gravity storage, recently secured US$28 million in project financing for its innovative Calistoga Resiliency Centre (CRC) in California. This funding will enable the development of a microgrid powered by a unique combination of green hydrogen and battery energy storage systems (BESS), marking a significant step forward in enhancing grid resilience in the face of natural disasters such as wildfires.

Located in California's fire-prone regions, the CRC is designed to provide critical backup power during Public Safety Power Shutoff (PSPS) events—periods when utility companies proactively cut power to prevent wildfires. These events can leave communities without electricity for extended periods, making the need for reliable, independent power sources more urgent as many utilities see benefits in energy storage today. The CRC, with a capacity of 293 MWh and a peak output of 8.5 MW, will ensure that the Calistoga community maintains power even when the grid is disconnected.

The CRC features an integrated hybrid system that combines lithium-ion batteries and green hydrogen fuel cells, even as some grid-scale projects adopt vanadium flow batteries for long-duration needs. During a PSPS event or other grid outages, the system will operate in "island mode," using hydrogen to generate electricity. This setup not only guarantees power supply but also contributes to grid stability by supporting black-start and grid-forming functions. Energy Vault's proprietary B-VAULT DC battery technology complements the hydrogen fuel cells, enhancing the overall performance and resilience of the microgrid.

One of the key aspects of the CRC project is the utilization of green hydrogen. Unlike traditional hydrogen, which is often produced using fossil fuels, green hydrogen is generated through renewable energy sources like solar or wind power, with large-scale initiatives such as British Columbia hydrogen project accelerating supply, making it a cleaner and more sustainable alternative. This aligns with California’s ambitious clean energy goals and is expected to reduce the carbon footprint of the region’s energy infrastructure.

The CRC project also sets a precedent for future hybrid microgrid deployments across California and other wildfire-prone areas, with utilities like SDG&E Emerald Storage highlighting growing adoption. Energy Vault has positioned the CRC as a model for scalable, utility-scale microgrids that can be adapted to various locations facing similar challenges. Following the success of this project, Energy Vault is expanding its portfolio with additional projects in Texas, where it anticipates securing up to US$25 million in financing.

The funding for the CRC also includes the sale of an investment tax credit (ITC), a key component of the financing structure that helps make such ambitious projects financially viable. This structure is crucial as it allows companies to leverage government incentives to offset development costs, including CEC long-duration storage funding, thus encouraging further investment in green energy infrastructure.

Despite some skepticism regarding the transportation of hydrogen rather than producing it onsite, the project has garnered strong support. California’s Public Utilities Commission (CPUC) acknowledged the potential risks of transporting green hydrogen but emphasized that it is still preferable to using more harmful fuel sources. This recognition is important as it validates Energy Vault’s approach to using hydrogen as part of a broader strategy to transition to clean, reliable energy solutions.

Energy Vault's shift from its traditional gravity-based energy storage systems to battery energy storage systems, such as BESS in New York, reflects the company's adaptation to the growing demand for versatile, efficient energy solutions. The hybrid approach of combining BESS with green hydrogen represents an innovative way to address the challenges of energy storage, especially in regions vulnerable to natural disasters and power outages.

As the CRC nears mechanical completion and aims for full commercial operations by Q2 2025, it is poised to become a critical part of California’s grid resilience strategy. The microgrid's ability to function autonomously during emergencies will provide invaluable benefits not only to Calistoga but also to other communities that may face similar grid disruptions in the future.

Energy Vault’s US$28 million financing for the Calistoga Resiliency Centre marks a significant milestone in the development of hybrid microgrids that combine the power of green hydrogen and battery energy storage. This project exemplifies the future of energy resilience, showcasing a forward-thinking approach to mitigating the impact of natural disasters and ensuring a reliable, sustainable energy future for communities at risk. With its innovative use of renewable energy sources and cutting-edge technology, the CRC sets a strong example for future energy storage projects worldwide.

Britain Electricity Demand During Lockdown is around 10 percent lower, as industrial consumers scale back. National Grid reports later morning peaks and continues balancing system frequency and voltage to maintain grid stability.

Key Points

Measured drop in UK power use, later morning peaks, and grid actions to keep frequency and voltage within safe limits.

✅ Daily demand about 10 percent lower since lockdown.

✅ Morning peak down nearly 18 percent and occurs later.

✅ National Grid balances frequency and voltage using flexible resources.

Daily electricity demand in Britain is around 10% lower than before the country went into lockdown last week due to the coronavirus outbreak, data from grid operator National Grid showed on Tuesday.

The fall is largely due to big industrial consumers using less power across sectors, the operator said.

Last week, Prime Minister Boris Johnson ordered Britons to stay at home to halt the spread of the virus, imposing curbs on everyday life without precedent in peacetime.

Morning peak demand has fallen by nearly 18% compared to before the lockdown was introduced and the normal morning peak is later than usual because the times people are getting up are later and more spread out with fewer travelling to work and school, a pattern also seen in Ottawa during closures, National Grid said.

Even though less power is needed overall, the operator still has to manage lower demand for electricity, as well as peaks, amid occasional short supply warnings from National Grid, and keep the frequency and voltage of the system at safe levels.

Last August, a blackout cut power to one million customers and caused transport chaos as almost simultaneous loss of output from two generators caused by a lightning strike caused the frequency of the system to drop below normal levels, highlighting concerns after the emergency energy plan stalled.

National Grid said it can use a number of tools to manage the frequency, such as working with flexible generators to reduce output or draw on storage providers to increase demand, and market conditions mean peak power prices have spiked at times.
