The curious carbon offset market

UK Energy Network Profits are under scrutiny as Ofgem price controls, Citizens Advice claims, and National Grid margins spark debate over monopolies, allowed returns, consumer bills, rebates, and future investment under tougher regulation.

Key Points

UK Energy Network Profits are returns set by Ofgem for regulated grid operators, shaping consumer bills and investment

✅ Ofgem sets allowed returns for monopoly networks via price controls

✅ Dispute over interest rates, bond yields, and risk premiums

✅ Reforms proposed: shorter controls, tougher investor incentives

Companies that run Britain’s electricity and gas networks, including National Grid, are making “eye-watering” profits at the expense of households, according to a well-known consumer group.

Citizens Advice believes £7.5bn in “unjustified” profits should be returned to consumers who pay for network costs via their electricity and gas bills, with parallels seen in a deferred BC Hydro costs report abroad, although its figures have been contested by the energy industry and regulator.

Ownership of electricity and gas networks came under the spotlight in the run-up to June’s general election, after the Labour party said in its manifesto it would bring both national and regional grid infrastructure to back into public ownership, amid wider debates about grid privatization concerns elsewhere, over time.

Electricity sector privatisation began in 1990 and the gas industry was privatised in 1986. Energy network companies — which own and operate the cables and wires that help deliver electricity and gas to homes and businesses — are in effect monopolies that are regulated by Ofgem. Ofgem evaluates what their costs, including the cost of capital to finance investments, might be over an eight-year “price control” period, similar to determinations like the OEB decision on Hydro One rates in Ontario, Canada. Citizens Advice claims many of the regulator’s calculations for the most recent price control went “considerably in networks’ financial favour”.

It believes assumptions Ofgem made about factors such as the future path of interest rates and returns on government bonds were too generous, with international contrasts like power theft challenges in India illustrating different risk contexts, as was the regulator’s assessment of the risk associated with operating a network company. 

These “generous” assumptions will lead to network companies making average profit margins of 19 per cent and an average return of 10 per cent for their investors at the expense of consumers, Citizens Advice claims in a report published on Wednesday, which recommends a shorter price control period to allow for more accurate forecasting.

“Decisions made by Ofgem have allowed gas and electricity network companies to make sky-high profits that we’ve found are not justified by their performance,” said Gillian Guy, chief executive of Citizens Advice. Ofgem defended its regulatory regime, saying it helped to cut costs, improve reliability and customer satisfaction. 

“Ofgem has already cut costs to consumers by 6 per cent in the current price control and secured a rebate of over £4.5bn from network companies and is engaging with the industry to deliver further savings, with some regions seeing Ontario electricity rate reductions for businesses as well,” said Dermot Nolan, chief executive of the energy regulator.

Mr Nolan insisted the next price controls would be “tougher for investors”. The current price controls for the gas and electricity transmission networks, plus gas distribution, run until 2021 and until 2023 for local electricity distribution networks.

“While we don’t agree with its modelling and the figures it has produced, the Citizens Advice report raises some important issues about network regulation which will be addressed in the next control,” Mr Nolan said.

The Energy Networks Association, a trade body, refuted the claims of Citizens Advice, insisting that costs had fallen by 17 per cent in real terms since privatisation. The current regulatory framework was established after a public consultation, it said, adding that today’s report repeated several old claims that had previously been rejected by the Competition and Markets Authority.

“Our energy networks are among the most reliable and lowest cost in the world and their performance has never been better. In the next six years energy network companies are forecasted to deliver £45bn of investment in the UK economy,” a spokesman for the networks association added. National Grid said that since 2013 it had generated savings of £460m for bill payers.

Los Angeles Power Station Fire prompts LADWP to shut a Northridge/Reseda substation, causing a San Fernando Valley outage amid a heatwave; high-voltage equipment and mineral oil burned as 94,000 customers lost power, elevator rescues reported.

Key Points

An LADWP substation fire in Northridge/Reseda caused a major outage; 94,000 customers affected as crews restore power.

✅ Fire started around 6:52 p.m.; fully extinguished by 9 p.m.

✅ High-voltage gear and mineral oil burned; no injuries reported.

✅ Outages hit Porter Ranch, Reseda, West Hills, Granada Hills.

About 94,000 customers were without electricity Saturday night after the Los Angeles Department of Water and Power shut down a power station in the northeast San Fernando Valley that caught fire, the agency said.

The fire at the station in the Northridge/Reseda area of Los Angeles started about 6:52 p.m. and involved equipment that carries high-voltage electricity and distributes it at lower voltages to customers in the surrounding area, the department said, even as other utilities sometimes deploy wildfire safety shut-offs to reduce risk during dangerous conditions.

The department shut off power to the station as a precautionary move, and it is restoring power now that the fire has been put out, similar to restoration after intentional shut-offs in other parts of California. Initially, 140,000 customers were without power. That number had been cut to 94,000 by 11 p.m.

The power outage comes as much of California baked in heat that broke records, and rolling blackout warnings were issued as the grid strained. A record that stood 131 years in Los Angeles was snapped when the temperature spiked at 98 degrees downtown.

People reported losing power in Porter Ranch, Winnetka, West Hills, Canoga Park, Woodland Hills, Granada Hills, North Hills, Reseda and Chatsworth, KABC TV reported, highlighting electricity inequality across communities.

Shortly after the blaze broke out, firefighters found a huge container of mineral oil that is used to cool electrical equipment on fire, Los Angeles Fire Department spokesman Brian Humphrey told the Los Angeles Times. The incident underscores infrastructure risks that in some regions have required a complete grid rebuild after severe storms.

Firefighters had the blaze under control by 8:30 p.m. and were able to put it out by 9 p.m., Humphrey said. "These were fierce flames, with smoke towering more than 300 feet into the sky," he told the newspaper.

No one was injured.

Firefighters rescued people who were stranded in elevators, Humphrey said.

Gander Curling Club Debt Forgiveness Agreement explained: town council tax relief, loan write-off conditions, community benefits, and economic impact, covering long-standing taxes and loans while protecting the facility with asset clauses and compliance terms.

Key Points

Town plan erasing 25 years of tax and loan debt, with conditions to keep the curling facility open for residents.

✅ Conditions: no borrowing against property without consent.

✅ Water and sewer taxes must be paid annually.

✅ If sold or use changes, debt due; transfer for $1.

Gander town council has agreed to forgive the local curling club's debt of over $250,000.

Gina Brown, chair of the town council's finance committee, says the agreement has been put in place to help the curling club survive, amid broader discussions on electricity affordability in Newfoundland and Labrador.

"When we took a look at this and realized there was a significant outstanding debt for Gander curling club … we have to mitigate," Brown told CBC Newfoundland Morning. "[Getting] what the taxpayers are owed, with also understanding and appreciating the role that that recreational facility plays in our community."

According to Brown, the debt comes from a combination of taxes and loans, going back about 25 years. She says the curling club understood there was debt, but didn't know the number was so high. The club has been in the black since 2007, but used their profits for other items like renovations.

"Like so many cases when you're dealing with an organization with a changing board, and the same for council … [people are] coming in and coming out," Brown said. "And as a result, my understanding from the curling club's perspective is they weren't aware of how much was outstanding."

Chris McLeod, president of the Gander Curling Club, told CBC the club had been trying to address the debt since he became president in 2014.

Terms of agreement
The town's agreement with the club comes with the following stipulations:

The club will not use the property as security for any form of borrowing without the town's consent.
 
The club will continue to pay water and sewer tax annually.
 
If the club sells the property, the town reserves the right to void the agreement and the debt will immediately become due in full.
 
If the club stops using the facility as a curling club, the property will be transferred to the town for $1.
McLeod says the club will not attempt to pay back the debt, as it is not part of the agreement. The only way the debt would be paid is if the building is sold, which McLeod says it won't be, and there are also no plans to use the building for anything other than a curling club.

"[The debt] is basically gone now," McLeod said.

McLeod says the move was made to help get the debt off the books, and make sure the curling club can be financially responsible in the future, similar to relief programs some utilities offered during the pandemic.

The curling club is something that encourages people. So we felt that this has to be maintained.
- Gina Brown

Brown says keeping the curling club in Gander is important for the town, and brings different benefits to the area, as regional power cooperation debates illustrate broader trends.

"They are servicing people from as young as Grade 1 to seniors," Brown said. "You need little to no equipment, you need no background. So for the town itself, for its social and health implications, as provinces advance emissions plans that can affect communities, is one. But the other thing is the economic benefit that comes from having this facility here."

The Gander Curling Club's debt forgiveness comes with several conditions. (Google Maps)
The curling club can help attract people into the community, as recreational facilities are often a key draw for families, she added, while other provinces are creating transition funds to support communities.

"When you're as a town, trying to attract people coming in … whether you're a doctor, nurse, anybody looking at the recreational facilities, the curling club is something that encourages people," Brown said. "So we felt that this has to be maintained."

Brown says the town understands they might be setting a precedent with other businesses in forgiving the debts of the curling club, as major infrastructure like B.C.'s Site C dam has faced budget overruns.

"That's another thing we had to consider, what kind of precedents are [we] establishing?" Brown said. "From our standpoint, I think one of the things about this agreement that we felt was beneficial to the town is that they have an asset, helping to avoid costly delays seen with large projects. And the asset is a great building. To us, the taxpayers are in a win-win situation."

New Zealand Energy Transition will electrify transport and industry with renewables, grid-scale solar, wind farms, geothermal, batteries, demand response, pumped hydro, and transmission upgrades to manage dry-year risk and winter peak loads.

Key Points

A shift to renewables and smart demand to decarbonise transport and industry while ensuring reliable, affordable power.

✅ Electrifies transport and industrial heat with renewables

✅ Uses demand response, batteries, and pumped hydro for resilience

✅ Targets 99%+ renewable supply, managing dry-year and peak loads

As fossil fuels are phased out over the coming decades, the Climate Change Commission (CCC) suggests electricity will take up much of the slack, aligning with the vision of a sustainable electric planet powering our vehicle fleet and replacing coal and gas in industrial processes.

But can the electricity system really provide for this increased load where and when it is needed? The answer is “yes”, with some caveats.

Our research examines climate change impacts on the New Zealand energy system. It shows we’ll need to pay close attention to demand as well as supply. And we’ll have to factor in the impacts of climate change when we plan for growth in the energy sector.

Demand for electricity to grow
While electricity use has not increased in NZ in the past decade, many agencies project steeply rising demand in coming years. This is partly due to both increasing population and gross domestic product, but mostly due to the anticipated electrification of transport and industry, which could result in a doubling of demand by mid-century.

It’s hard to get a sense of the scale of the new generation required, but if wind was the sole technology employed to meet demand by 2050, between 10 and 60 new wind farms would be needed nationwide.

Of course, we won’t only build wind farms, as renewables are coming on strong and grid-scale solar, rooftop solar, new geothermal, some new small hydro plant and possibly tidal and wave power will all have a part to play.

Managing the demand
As well as providing more electricity supply, demand management and batteries will also be important. Our modelling shows peak demand (which usually occurs when everyone turns on their heaters and ovens at 6pm in winter) could be up to 40% higher by 2050 than it is now.

But meeting this daily period of high demand could see expensive plant sitting idle for much of the time (with the last 25% of generation capacity only used about 10% of the time).

This is particularly a problem in a renewable electricity system when the hydro lakes are dry, as hydro is one of the few renewable electricity sources that can be stored during the day (as water behind the dam) and used over the evening peak (by generating with that stored water).

Demand response will therefore be needed. For example, this might involve an industrial plant turning off when there is too much load on the electricity grid.

But by 2050, a significant number of households will also need smart appliances and meters that automatically use cheaper electricity at non-peak times. For example, washing machines and electric car chargers could run automatically at 2am, rather than 6pm when demand is high.

Our modelling shows a well set up demand response system could mitigate dry-year risk (when hydro lakes are low on water) in coming decades, where currently gas and coal generation is often used.

Instead of (or as well as) having demand response and battery systems to combat dry-year risk, a pumped storage system could be built. This is where water is pumped uphill when hydro lake inflows are plentiful, and used to generate electricity during dry periods.

The NZ Battery project is currently considering the potential for this in New Zealand, and debates such as whether we would use Site C's electricity offer relevant lessons.

Almost (but not quite) 100% renewable
Dry-year risk would be greatly reduced and there would be “greater greenhouse gas emissions savings” if the Interim Climate Change Committee’s (ICCC) 2019 recommendation to aim for 99% renewable electricity was adopted, rather than aiming for 100%.

A small amount of gas-peaking plant would therefore be retained. The ICCC said going from 99% to 100% renewable electricity by overbuilding would only avoid a very small amount of carbon emissions, at a very high cost.

Our modelling supports this view. The CCC’s draft advice on the issue also makes the point that, although 100% renewable electricity is the “desired end point”, timing is important to enable a smooth transition.

Despite these views, Energy Minister Megan Woods has said the government will be keeping the target of a 100% renewable electricity sector by 2030.

Impacts of climate change
In future, the electricity system will have to respond to changing climate patterns as well, becoming resilient to climate risks over time.

The National Institute of Water and Atmospheric Research predicts winds will increase in the South Island and decrease in the far north in coming decades.

Inflows to the biggest hydro lakes will get wetter (more rain in their headwaters), and their seasonality will change due to changes in the amount of snow in these catchments.

Our modelling shows the electricity system can adapt to those changing conditions. One good news story (unless you’re a skier) is that warmer temperatures will mean less snow storage at lower elevations, and therefore higher lake inflows in the big hydro catchments in winter, leading to a better match between times of high electricity demand and higher inflows.

The price is right
The modelling also shows the cost of generating electricity is not likely to increase, because the price of building new sources of renewable energy continues to fall globally.

Because the cost of building new renewables is now cheaper than non-renewables (such as coal-fired plants), investing in carbon-free electricity is increasingly compelling, and renewables are more likely to be built to meet new demand in the near term.

While New Zealand’s electricity system can enable the rapid decarbonisation of (at least) our transport and industrial heat sectors, international efforts like cleaning up Canada's electricity underline the need for certainty so the electricity industry can start building to meet demand everywhere.

Bipartisan cooperation at government level will be important to encourage significant investment in generation and transmission projects with long lead times and life expectancies, as analyses of climate policy and grid implications underscore in comparable markets.

Infrastructure and markets are needed to support demand response uptake, as well as certainty around the Tiwai exit in 2024 and whether pumped storage is likely to be built.

Our electricity system can support the rapid decarbonisation needed if New Zealand is to do its fair share globally to tackle climate change.

But sound planning, firm decisions and a supportive and relatively stable regulatory framework are all required before shovels can hit the ground.

When Mike Holland talks about small modular nuclear reactors, he sees dollar signs.

When the Green Party hears about them, they see danger signs.

The loquacious Progressive Conservative minister of energy development recently quoted NB Power's eye-popping estimates of the potential economic impact of the reactors: thousands of jobs and a $1 billion boost to the provincial economy.

"New Brunswick is positioned to not only participate in this opportunity, but to be a world leader in the SMR field," Holland said in the legislature last month.

'Huge risk' nuclear deal could let Ontario push N.B. aside, says consultant
'Many issues' with modular nuclear reactors says environmental lawyer
Green MLAs David Coon and Kevin Arseneau responded cheekily by ticking off the Financial and Consumer Services Commission's checklist on how to spot a scam.

Is the sales pitch from a credible source? Is the windfall being promised by a reputable institution? Is the risk reasonable?

For small nuclear reactors, they said, the answer to all those questions is no. 

"The last thing we need to do is pour more public money down the nuclear-power drain," Coon said, reminding MLAs of the Point Lepreau refurbishment project that went $1 billion over budget.

The Greens aside, New Brunswick politicians have embraced small modular reactors, which they say can both create jobs and help solve the climate crisis.

Smaller and cheaper, supporters say
They're "small" because, depending on the design, they would generate from three to 300 megawatts of electricity, less than, for example, Point Lepreau's 660 megawatts.

It's the modular design that is supposed to make them more affordable. Rather than being built from scratch on site, components are to be manufactured elsewhere, sometimes in existing factories, then shipped and assembled.. 

Under Brian Gallant, the Liberals handed $10 million to two Saint John companies working on SMRs, ARC Nuclear and Moltex Energy.

Greens point to previous fiascoes
The Greens and other opponents of nuclear power fear SMRS are the latest in a long line of silver-bullet fiascoes, from the $23 million spent on the Bricklin in 1975 to $63.4 million in loans and loan guarantees to the Atcon Group a decade ago.

"It seems that [ARC and Moltex] have been targeting New Brunswick for another big handout ... because it's going to take billions of dollars to build these things, if they ever get off the drawing board," said Susan O'Donnell, a University of New Brunswick researcher.

O'Donnell, who studies technology adoption in communities, is part of a small new group called the Coalition for Responsible Energy Development formed this year to oppose SMRs.

"What we really need here is a reasonable discussion about the pros and cons of it," she said.

Government touts economic spinoffs
According to the Higgs government's throne speech last month, if New Brunswick companies can secure just one per cent of the Canadian market for small reactors, the province would see $190 million in revenue. 

The figures come from a study conducted for NB Power by University of Moncton economist Pierre-Marcel Desjardins.

But a four-page public summary does not include any sales projections and NB Power did not provide them to CBC News. 

"What we didn't see was a market analysis," O'Donnell said. "How viable is the market? … They're all based on a hypothetical market that probably doesn't exist."

O'Donnell said her group asked for the full report but was told it's confidential because it contains sensitive commercial information.

Holland said he's confident there will be buyers. 

"It won't be hard to find communities that will be looking for a cost effective, affordable, safe alternative to generate their electricity and do it in a way that emits zero emissions," he said.

SMRs come in different sizes and while some proponents talk about using "micro" reactors to provide electricity to remote northern First Nations communities, ARC and Moltex plan larger models to sell to power utilities looking to shift away from coal and gas.

"We have utilities and customers across Canada, across the United States, across Asia and Europe saying they desperately want a technology like this," said Moltex's Saint John-based CEO for North America Rory O'Sullivan. 

"The market is screaming for this product," he said, adding "all of the utilities" in Canada are interested in Moltex's reactors

ARC's CEO Norm Sawyer is more specific, guessing 30 per cent of his SMR sales will be in Atlantic Canada, 30 per cent in Ontario and 40 per cent in Alberta and Saskatchewan — all provincial power grids.

O'Donnell said it's an important question because without a large number of guaranteed sales, the high cost of manufacturing SMRs would make the initiative a money-loser. 

The cost of building the world's only functioning SMR, in Russia, was four times what was expected. 

An Australian government agency said initial cost estimates for such major projects "are often initially too low" and can "overrun." 

Up-front costs can be huge
University of British Columbia physicist M.V. Ramana, who has authored studies on the economics of nuclear power, said SMRs face the same financial reality as any large-scale manufacturing.

"You're going to spend a huge amount of money on the basic fixed costs" at the outset, he said, with costs per unit becoming more viable only after more units are built and sold. 

He estimates a company would have to build and sell more than 700 SMRs to break even, and said there are not enough buyers for that to happen. 

But Sawyer said those estimates don't take into account technological advances.

"A lot of what's being said ... is really based on old technology," he said, estimating ARC would be viable even if it sold an amount of reactors in the low double digits. 

O'Sullivan agrees.

"In fact, just the first one alone looks like it will still be economical," he said. "In reality, you probably need a few … but you're talking about one or two, maximum three [to make a profit] because you don't need these big factories."

'Paper designs' prove nothing, says expert
Ramana doesn't buy it. 

"These are all companies that have been started by somebody who's been in the nuclear industry for some years, has a bright idea, finds an angel investor who's given them a few million dollars," he said.

"They have a paper design, or a Power Point design. They have not built anything. They have not tested anything. To go from that point … to a design that can actually be constructed on the field is an enormous amount of work." 

Both CEOs acknowledge the skepticism about SMRs.

'The market is screaming for this product,' said Moltex’s Saint John-based CEO for North America, Rory O’Sullivan. (Brian Chisholm, CBC)
"I understand New Brunswick has had its share of good investments and its share of what we consider questionable investments," said Sawyer, who grew up in Rexton.

But he said ARC's SMR is based on a long-proven technology and is far past the on-paper design stage "so you reduce the risk." 

Moltex is now completing the first phase of the Canadian Nuclear Safety Commission's review of its design, a major hurdle. ARC completed that phase last year.

But, Ramana said there are problems with both designs. Moltex's molten salt model has had "huge technical challenges" elsewhere while ARC's sodium-cooled system has encountered "operational difficulties."

Ottawa says nuclear is needed for climate goals
The most compelling argument for looking at SMRs may be Ottawa's climate change goals.  

The national climate plan requires NB Power to phase out burning coal at its Belledune generating station by 2030. It's scrambling to find a replacement source of electricity.

The Trudeau government's throne speech in October promised to "support investments in renewable energy and next-generation clean energy and technology solutions."

And federal Natural Resources Minister Seamus O'Regan told CBC earlier this year that he's "very excited" about SMRs.

"We have not seen a model where we can get to net-zero emissions by 2050 without nuclear,"  he said.

O'Donnell said while nuclear power doesn't emit greenhouse gases, it's hardly a clean technology because of the spent nuclear fuel waste. 

Government support is key 
She also wonders why, if SMRs make so much sense, ARC and Moltex are relying so much on government money rather than private capital.

Holland said "the vast majority" of funding for the two companies "has to come from private sector investments, who will be very careful to make sure they get a return on that investment."

Sawyer said ARC has three dollars for every dollar it has received from the province, and General Electric has a minority ownership stake in its U.S.-based parent company.

O'Sullivan said Moltex has attracted $5 million from a European engineering firm and $6 million from "the first-ever nuclear crowdfunding campaign." 

But he said for new technologies, including nuclear power, "you need government to show policy support.

"Nuclear technology has always been developed by governments around the world. This is a very new change to have an industry come in and lead this, so private investors can't take the risk to do that on their own," he said. 

So far, Ottawa hasn't put up any funding for ARC or Moltex. During the provincial election campaign, Higgs implied federal money was imminent, but there's been no announcement in the almost three months since then.

Last month the federal government announced $20 million for Terrestrial Energy, an Ontario company working on SMRs.

"We know we have the best technology pitch," O'Sullivan said. "There's others that are slightly more advanced than us, but we have the best overall proposition and we think that's going to win out at the end of the day."

But O'Donnell said her group plans to continue asking questions about SMRs. 

"I think what we really need is to have an honest conversation about what these are so that New Brunswickers can have all the facts on the table," she said.

Virtual Power Plants orchestrate distributed energy resources like rooftop solar, home batteries, and EVs to deliver grid services, demand response, peak shaving, and resilience, lowering costs while enhancing reliability across wholesale markets and local networks.

Key Points

Virtual Power Plants aggregate solar and batteries to provide grid services, cut peak costs, and boost reliability.

✅ Aggregates DERs via cloud to bid into wholesale markets

✅ Reduces peak demand, defers costly grid upgrades

✅ Enhances resilience vs outages, cyber risks, and wildfires

If “virtual” meetings can allow companies to gather without anyone being in the office, then remotely distributed solar panels and batteries can harness energy and act as “virtual power plants.” It is simply the orchestration of millions of dispersed assets within a smarter electricity infrastructure to manage the supply of electricity — power that can be redirected back to the grid and distributed to homes and businesses. 

The ultimate goal is to revamp the energy landscape, making it cleaner and more reliable. By using onsite generation such as rooftop solar and smart solar inverters in combination with battery storage, those services can reduce the network’s overall cost by deferring expensive infrastructure upgrades and by reducing the need to purchase cost-prohibitive peak power. 

“We expect virtual power plants, including aggregated home solar and batteries, to become more common and more impactful for energy consumers throughout the country in the coming years,” says Michael Sachdev, chief product officer for Sunrun Inc., a rooftop solar company, in an interview. “The growth of home solar and batteries will be most apparent in places where households have an immediate need for backup power, as they do in California, where grid reliability pressures have led utilities to turn off the electricity to reduce wildfire risk.”

Home battery adoption, such as Tesla Powerwall systems, is becoming commonplace in Hawaii and in New England, he adds, because those distributed assets are improving the efficiency of the electrical network. It is a trend that is reshaping the country’s energy generation and delivery system by relying more on clean onsite generation and less on fossil fuels.

Sunrun has recently formed a business partnership with AutoGrid, which will manage Sunrun’s fleet of rechargeable batteries. It is a cloud-based system that allows Sunrun to work with utilities to dispatch its “storage fleet” to optimize the economic results. AutoGrid compiles the data and makes AI-driven forecasts that enable it to pinpoint potential trouble spots. 

But a distributed energy system, or a virtual power plant, would have 200,000 subsystems. Or, 200,000 5 kilowatt batteries would be the equivalent of one power plant that has a capacity of 1,000 megawatts. 

“A virtual power plant acts as a generator,” says Amit Narayan, chief executive officer of AutoGrid, in an interview. “It is one of the top five innovations of the decade. If you look at Sunrun, 60% of every solar system it sells in the Bay Area is getting attached to a battery. The value proposition comes when you can aggregate these batteries and market them as a generation unit. The pool of individual assets may improve over time. But when you add these up, it is better than a large-scale plant. It is like going from mainframe computers to laptops.”

The AutoGrid executive goes on to say that centralized systems are less reliable than distributed resources. While one battery could falter, 200,000 of them that operate from remote locations will prove to be more durable — able to withstand cyber attacks and wildfires. Sunrun’s Sachdev adds that the ability to store energy in batteries, as seen in California’s expanding grid-scale battery use supporting reliability, and to move it to the grid on demand creates value not just for homes and businesses but also for the network as a whole.

The good news is that the trend worldwide is to make it easier for smaller distributed assets, including energy storage for microgrids that support local resilience, to get the same regulatory treatment as power plants. System operators have been obligated to call up those power supplies that are the most cost-effective and that can be easily dispatched. But now regulators are giving virtual power plants comprised of solar and batteries the same treatment. 

In the United States, for example, the Federal Energy Regulatory Commission issued an order in 2018 that allows storage resources to participate in wholesale markets — where electricity is bought directly from generators before selling that power to homes and businesses. Under the ruling, virtual power plants are paid the same as traditional power suppliers. A federal appeals court this month upheld the commission’s order, saying that it had the right to ensure “technological advances in energy storage are fully realized in the marketplace.” 

“In the past, we have used back-up generators,” notes AutoGrid’s Narayan. “As we move toward more automation, we are opening up the market to small assets such as battery storage and electric vehicles. As we deploy more of these assets, there will be increasing opportunities for virtual power plants.” 

Virtual power plants have the potential to change the energy horizon by harnessing locally-produced solar power and redistributing that to where it is most needed — all facilitated by cloud-based software that has a full panoramic view. At the same time, those smaller distributed assets can add more reliability and give consumers greater peace-of-mind — a dynamic that does, indeed, beef-up America’s generation and delivery network.
