Peer-to-peer energy breakthrough could allow solar and wind energy sources to be shared

Canada 2023 Clean Energy Outlook highlights decarbonization, renewables, a net-zero grid by 2035, hydrogen, energy storage, EV mandates, carbon pricing, and critical minerals, aligning with IRA incentives and provincial policies to accelerate the transition.

Key Points

A concise overview of Canada's 2023 path to net-zero: renewables, clean grids, storage, EVs, and hydrogen.

✅ Net-zero electricity regulations target 2035

✅ Alberta leads PPAs and renewables via deregulated markets

✅ Tax credits boost storage, hydrogen, EVs, and critical minerals

The year 2022 may go down as the most successful one yet for climate action. It was marked by monumental shifts in energy policy from governments, two COP meetings and heightened awareness of the private sector's duty to act.

In the U.S., the Inflation Reduction Act (IRA) was the largest federal legislation to tackle climate change, injecting $369 billion of tax credits and incentives for clean energy, Biden's EV agenda and carbon capture, energy storage, energy efficiency and research.

The European Union accelerated its green policies to transition away from fossil fuels and overhauled its carbon market. China and India made strides on clean energy and strengthened climate policies. The International Energy Agency made its largest revision yet as renewables continued to proliferate.

The U.S. ratified the Kigali Amendment, one of the strongest global climate policies to date.

Canada was no different. The 2022 Fall Economic Statement was announced to respond to the IRA, offering an investment tax credit for renewables, clean technology and green hydrogen alongside the Canada Growth Fund. The federal government also proposed a 2035 deadline for clean electrical grids and a federal zero-emissions vehicle (ZEV) sales mandate for light-duty vehicles.

With the momentum set, more action is promised in 2023: Canadian governments are expected to unveil firmer details for the decarbonization of electricity grids to meet 2035 deadlines; Alberta is poised to be an unlikely leader in clean energy.

Greater attention will be put on energy storage and critical minerals. Even an expected economic downturn is unlikely to stop the ball that is rolling.

Shane Doig, the head of energy and natural resources at KPMG in Canada, said events in 2022 demonstrated the complexity of the energy transformation and opened “a more balanced conversation around how Canada can transition to a lower carbon footprint, whilst balancing the need for affordable, readily available electricity.”

Expect further developments on clean electricity
2023 shapes up as a crucial year for Canada’s clean electricity grid.

The federal government announced it will pursue a net-zero electricity grid by 2035 under the Clean Electricity Regulations (CER) framework.

It requires mass renewable and clean energy adoption, phasing out fossil fuel electricity generation, rapid electrification and upgrading transmission and storage while accommodating growth in electricity demand.

The first regulations for consultation are expected early in 2023. The plans will lay out pollution regulations and costs for generating assets to accelerate clean energy adoption, according to Evan Pivnick, the clean energy program manager of Clean Energy Canada.

The Independent Energy System Operator of Ontario (IESO) recently published a three-part report suggesting a net-zero conversion for Ontario could cost $400 billion over 25 years, even as the province weighs an electricity market reshuffle to keep up with increasing electricity demand.

Power Utility released research by The Atmospheric Fund that suggests Ontario could reach a net-zero grid by 2035 across various scenarios, despite ongoing debates about Ontario's hydro plan and rate design.

Dale Beguin, executive vice president at the Canadian Climate Institute, said in 2023 he hopes to see more provincial regulators and governments send “strong signals to the utilities” that a pathway to net-zero is realistic.

He recounted increasing talk from investors in facilities such as automotive plants and steel mills who want clean electricity guarantees before making investments. “Clean energy is a comparative advantage,” he said, which puts the imperative on organizations like the IESO to lay out plans for bigger, cleaner and flexible grids.

Beguin and Pivnick said they are watching British Columbia closely because of a government mandate letter setting a climate-aligned energy framework and a new mandate for the British Columbia Utilities Commission. Pivnick said there may be lessons to be drawn for other jurisdictions.

Alberta’s unlikely rise as a clean energy leader
Though Alberta sits at the heart of Canada’s oil and gas industry and at the core of political resistance to climate policy, it has emerged as a front runner in renewables adoption.

Billion of dollars for wind and solar projects have flowed into Alberta, as the province charts a path to clean electricity with large-scale projects.

Pivnick said an “underappreciated story” is how Alberta leaned into renewables through its “unique market.” Alberta leads in renewables and power purchase agreements because of its deregulated electricity market.

Unlike most provinces, Alberta enables companies to go directly to solar and wind developers to strike deals, a model reinforced under Kenney's electricity policies in recent years, rather than through utilities. It incentivizes private investment, lowers costs and helps meet increasing demand, which Nagwan Al-Guneid, the director of the Business Renewables Centre - Canada at the Pembina Institute, said is “is the No. 1 reason we see this boom in renewables in Alberta.”

Beguin noted Alberta’s innovative ‘reverse auctions,’ where the province sets a competitive bidding process to provide electricity. It ended up making electricity “way cheaper” due to the economic competitiveness of renewables, while Alberta profited and added clean energy to its grid.

In 2019, the Business Renewables Centre-Canada established a target of 2 GW of renewable energy deals by 2025. The target was exceeded in 2022, which led to a revised goal for 10 GW of renewables by 2030.

Al-Guneid wants to see other jurisdictions help more companies buy renewables. She does not universally prescribe deregulation, however, as other mechanisms such as sleeving exist.

Alberta will update its industrial carbon pricing in 2023, requiring large emitters to pay $65 per tonne of carbon dioxide. The fee climbs $15 per tonne each year until it reaches $175 per tonne in 2030. Al-Guneid said as the tax increases, demand for renewable energy certificates will also increase in Alberta.

Pivnick noted Alberta will have an election in 2023, which could have ramifications for energy policy.

Batteries and EV leadership
Manufacturing clean energy equipment, batteries and storage requires enormous quantities of minerals. With the 2022 Fall Economic Statement and the Critical Minerals Strategy, Canada is taking important steps to lead on this front.

Pivnick pointed to battery supply chain investments in Ontario and Quebec as part of Canada’s shift from “a fuel-based (economy) to a materials-based economy” to provide materials necessary for wind turbines and solar panels. The Strategy showed an understanding Canada has a major role to meet its allies’ needs for critical minerals, whether it’s the resources or supply chains.

There is also an opportunity for Canada to forge ahead on energy storage. The Fall Economic Statement proposes a 30 per cent tax credit for investments into energy storage. Pivnick suggested Canada invest further into research and development to explore innovations like green hydrogen and pump storage.

Doig believes Canada is “well poised” for batteries, both in terms of the technology and sustainable mining of minerals like cobalt, lithium and copper. He is bullish for Canada’s electrification based on its clean energy use and increased spending on renewables and energy storage.

He said the federal ZEV mandate will drive increased demand for the power, utilities, and oil and gas industries to respond.

The majority of gas stations, which are owned by the nation’s energy industry, will need to be converted into EV charging stations.

Offsetting a recession 
One challenge will be a poor economic forecast in the near term. A short "technical recession" is expected in 2023.

Inflation remains stubbornly high, which has forced the Bank of Canada to hike interest rates. The conditions will not leave any industry unscathed, but Doig said Canada's decarbonization is unlikely to be halted.

“Whilst a recession would slow things down, the concern around energy security definitely helps offset that concern,” he said.

Amid rising trade frictions and tariff threats, energy security is top of mind for governments and private organizations, accelerating the shift to renewables.

Doig said there is a general feeling a recession would be short-lived, meaning it would be unlikely to impact long-term projects in hydrogen, liquified natural gas, carbon capture and wind and solar.

UK Petrol Shortages Drive EV Adoption as fuel crisis spurs electric vehicles, plug-in car demand, home charging, lower running costs, zero-emission mobility, ULEZ compliance, accelerating the shift from diesel to battery EVs.

Key Points

Fuel shortages push drivers to EVs, boosting inquiries and sales while highlighting the convenience of home charging.

✅ Surge in EV dealer inquiries and test drives

✅ Home charging avoids queues and fuel shortages

✅ Policy signals: ULEZ expansion, 2030 ICE ban

Sellers of plug-in vehicles say petrol shortages are driving people to adopt the new technology as the age of electric cars accelerates worldwide.

As petrol stations in parts of the UK started running out of fuel on Friday, business at Martin Miller’s electric car dealership in Guildford, Surrey, started soaring.

After what ended up being his company EV Experts busiest day ever, interest does not appear to be dying down. This week the diary is booked up with test drives and the business is low on stock amid supply constraints.

“People buy electric cars for environmental reasons, for cost-saving reasons and because the technology’s great, even though higher upfront prices remain a concern,” he said. “But Friday was one of those moments where people said, ‘Do you know what, this is a sign that we need to go electric’.”

While scenes of chaos play out at petrol stations across the country amid shortages, for many electric vehicle (EV) dealers the fuel crisis has led to an unexpected surge in inquiries and sales, even as some question an electric-car revolution narrative today.

EVA England, a non-profit representing new and prospective EV drivers, reports a rise in electric car inquiries and in interest at EV dealers, particularly in the last week.

“Saturday was bonkers but Friday even surpassed that, it was very strange,” said Miller, who founded his company four years ago. “I’ve now got trade-in cars with no petrol to move them.”

Along with existing factors such as the expansion of London’s ultra-low emission zone, the fuel crisis has proved to be another trigger point, he said. “People were using it as ‘this is the moment where I’m not going to put this off any longer’.”

The EV market is no longer the preserve of innovators and early adopters, he said, with the most popular models the Nissan Leaf, Volkswagen ID 3 and Jaguar I-Pace.

Ben Strzalko, the owner of Electric Cars UK in Leyland, Lancashire, said that as a small business it would take a few months to feel the knock-on effect of the fuel crisis on sales.

But every time there are problems with petrol or diesel, he said they acted as “one more tick for people making that transition to electric cars”.

He said “a lot of electric car owners will be chuffed to bits this last week” being able to plug in their cars at home. And as an EV driver himself, he admitted feeling a little smug as he drove past queues of 20 cars outside petrol stations over the weekend in his Tesla.

Matt Cleevely, the owner of Cleevely Electric Vehicles in Cheltenham, Gloucestershire, which specialises in used EVs, had a surge of inquiries over the weekend and on Monday morning from customers citing the fuel crisis as a reason for switching to electric.

He expects enthusiasm to continue rising, with petrol shortages adding “fuel to the fire”.

Although he feels sorry for non-EV drivers who have been unable to get fuel, he said as an electric car owner it was “very nice” not to have to worry about where to get petrol at the weekend.

“It’s very convenient that we’ve been able to just fuel up on our driveway. It’s one of the biggest pros of having an electric vehicle.”

The National Franchised Dealers Association also said multiple dealers have reported a spike in EV enquiries since the start of the crisis.

The Society of Motor Manufacturers and Traders reported “bumper growth” in the sale of plug-in cars in July, reflecting broader global market growth in recent years, with battery electric vehicles comprising 9% of sales. Plug-in hybrids accounted for 8% of sales and hybrid electric vehicles nearly 12%. Also in July, more electric vehicles were registered than diesel for the second consecutive month.

The UK has pledged to ban the sale of new petrol and diesel cars by 2030 and of new hybrids by 2035, a timeline that aligns with expectations that within a decade most driving could be electric.

Warren Philips, the volunteer communities director at EVA England, said the tipping point for EVs had already been reached but the fuel crisis “underlines how electric cars could work for the majority of people”.

He added: “The interest is already there, this just adds to it. And going forward with things like Cop26, with the climate crisis, with the cost of fuel probably going to rise … people will start looking at electric cars where you just skip that entire step.”

France EV Incentive Rules prioritize EU-made electric vehicles, tying subsidies to manufacturing emissions and carbon footprint, making Stellantis, Renault, and Tesla Model Y eligible while excluding many China-built models under a new eligibility list.

Key Points

Links EV subsidies to manufacturing emissions, favoring EU-made models and restricting many China-built cars.

✅ Subsidies tied to lifecycle manufacturing emissions.

✅ EU production favored; many China-built EVs excluded.

✅ Eligible: Stellantis, Renault, Tesla Model Y; not Model 3.

France's revamped new EV rules on consumer cash incentives for electric car purchases favour vehicles made in France and Europe over models manufactured in China, a government list of eligible car types published recently has showed.

Some 65% of electric cars sold in France will be eligible for the scheme, which from Friday will include new criteria covering the amount of carbon emitted in the manufacturing of an electric vehicle (EV).

The list of eligible models includes 24 produced by Franco-Italian group Stellantis (STLAM.MI) and five by French carmaker Renault (RENA.PA). Elon Musk's Tesla (TSLA.O) Model Y will be eligible but not its Model 3.

Electric vehicle brand MG Motors, owned by China's SAIC, said it expects the new rules to weigh on the French EV market, despite the global surge in EV sales seen in recent years.

"There are cars that will entirely lose their competitiveness", an MG spokesperson told Reuters, adding that the brand had decided not to apply for the bonus scheme for its MG4 model because it was "designed to exclude us".

French Finance Minister Bruno Le Maire hailed what he called the new rules' incentive for automakers to reduce their carbon footprint.

"We will no longer be subsidising car production that emits too much CO2," he said in a statement.

President Emmanuel Macron's government has wanted to make French and European-made EVs more affordable for domestic consumers relative to cheaper vehicles produced in China, amid a record EV market share in the country.

The average retail price of an EV in Europe, even as the EU EV share grew during lockdown months, was more than 65,000 euros ($71,000) in the first half of 2023, compared with just over 31,000 euros in China, according to research by Jato Dynamics.

The French government already offered buyers a cash incentive of between 5,000 and 7,000 euros to get more electric cars on the road, at a total cost of 1 billion euros ($1.1 billion) per year.

However, in the absence of cheap European-made EVs, a third of all incentives are going to consumers buying EVs made in China, French finance ministry officials say. The trend has helped spur a surge in imports and a growing competitive gap with domestic producers.

China's auto industry relies heavily on coal-generated electricity, meaning many Chinese-made EVs will henceforth not qualify.

The Ademe agency overseeing the process studied the eligibility of almost 500 EV models and their variants to include in the scheme.

Dacia, the low-cost Renault brand, saw its Spring model imported from China excluded from the list.

Tesla's Model 3 is made in China. The Model Y, which is larger and more expensive, is made mainly in Berlin and was the top selling EV in France over the first 11 months of the year, amid forecasts that EVs could dominate within a decade in many markets.

Ontario EV V2G Pilots enable bi-directional charging, backup power, and grid services with IESO, Toronto Hydro, and Hydro One, linking energy storage, solar, blockchain apps, and demand response incentives for smarter electrification.

Key Points

Ontario EV V2G pilots test bidirectional charging and backup power to support grid services with apps and incentives.

✅ Tests Nissan Leaf V2H backup with Hydro One and Peak Power.

✅ Integrates solar, storage, blockchain apps via Sky Energy and partners.

✅ Pilots demand response apps in Toronto and Waterloo utilities.

Electric vehicle owners in Ontario may one day be able to use the electricity in their EVs instead of loud diesel or gas generators to provide emergency power during blackouts. They could potentially also sell back energy to the grid when needed. Both are key areas of focus for new pilot projects announced this week by Ontario’s electricity grid operator and partners that include Toronto Hydro and Ontario Hydro.

Three projects announced this week will test the bi-directional power capabilities of current EVs and the grid, all partially funded by the Independent Electricity System Operator (IESO) of Ontario, with their announcement in Toronto also attended by Ontario Energy Minister Todd Smith.

The first project is with Hydro One Networks and Peak Power, which will use up to 10 privately owned Nissan Leafs to test what is needed technically to support owners using their cars for vehicle-to-building charging during power outages. It will also study what type of financial incentives will convince EV owners to provide backup power for other users, and therefore the grid.

A second pilot program with solar specialist Sky Energy and engineering firm Hero Energy will study EVs, energy storage, and solar panels to further examine how consumers with potentially more power to offer the grid could do it securely, in part using blockchain technology. York University and Volta Research are other partners in the program, which has already produced an app that can help drivers choose when and how much power to provide the grid — if any.

The third program is with local utilities in Toronto and Waterloo, Ont., and will test a secure digital app that helps EV drivers see the current demands on the grid through improved grid coordination mechanisms, and potentially price an incentive to EV drivers not to charge their vehicles for a few hours. Drivers could also be actively further paid to provide some of the charge currently in their vehicle back to the grid.

It all adds up to $2.7 million in program funding from IESO ($1.1 million) and the associated partners.

“An EV charged in Ontario produces roughly three per cent of emissions of a gas fuelled car,” said IESO’s Carla Nell, vice-president of corporate relations and innovation at the announcement near Peak Power chargers in downtown Toronto. “We know that Ontario consumers are buying EVs, and expected to increase tenfold — so we have to support electrification.”

If these types of programs sound familiar, it may be because utilities in Ontario have been testing such vehicle-to-grid technologies soon after affordable EVs became available in the fall of 2011. One such program was run by PowerStream, now the called Alectra, and headed by Neetika Sathe, who is now Alectra’s vice-president of its Green Energy and Technology (GRE&T) Centre in Guelph, Ont.

The difference between now and those tests in the mid-2010s is that the upcoming wave of EV sales can be clearly seen on the horizon, and California's grid stability work shows how EVs can play a larger role.

“We can see the tsunami now,” she said, noting that cost parity between EVs and gas vehicles is likely four or five years away — without government incentives, she stressed. “Now it’s not a question of if, it’s a question of when — and that when has received much more clarity on it.”

Sathe sees a benefit in studying all these types of bi-directional power-flowing scenarios, but notes that they are future scenarios for years in the future, especially since bi-directional charging equipment — and the vehicles with this capability — are pricey, and largely still not here. What she believes is much closer is the ability to automatically communicate what the grid needs with EV drivers, as Nova Scotia Power pilots integration, and how they could possibly help. For a price, of course.

“If I can set up a system that says ‘oh, the grid is stressed, can you not charge for the next two hours? And here’s what we’ll offer to you for that,’ that’s closer to low-hanging fruit,” she said, noting that Alectra is currently testing out such systems. “Think of it the same way as offering your car for Uber, or a room on Airbnb.”

Shanghai Electric PEM Hydrogen R&D Center advances green hydrogen via PEM electrolysis, modular megawatt electrolyzers, zero carbon production, and full-chain industrial applications, accelerating decarbonization, clean energy integration, and hydrogen economy scale-up across China.

Key Points

A joint R&D hub advancing PEM electrolysis, modular megawatt systems, and green hydrogen industrialization.

✅ Megawatt modular PEM electrolyzer design and system integration

✅ Zero-carbon hydrogen targeting mobility, chemicals, and power

✅ Full-chain collaboration from R&D to EPC and demonstration projects

Shanghai Electric has reached an agreement with the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences (the "Dalian Institute") to inaugurate the Proton Exchange Membrane (PEM) Hydrogen Production Technology R&D Center on March 4. The two parties signed a project cooperation agreement on Megawatt Modular and High-Efficiency PEM Hydrogen Production Equipment and System Development, marking an important step forward for Shanghai Electric in the field of hydrogen energy.

As one of China's largest energy equipment manufacturers, Shanghai Electric is at the forefront in the development of green hydrogen as part of China's clean energy drive. During this year's Two Sessions, the 14th Five-Year Plan was actively discussed, in which green hydrogen features prominently, and Shell's 2060 electricity forecast underscores the scale of electrification. With strong government support and widespread industry interest, 2021 is emerging as Year Zero for the hydrogen energy industry.

Currently, Shanghai Electric and the Dalian Institute have reached a preliminary agreement on the industrial development path for new energy power generation and electrolyzed water hydrogen production. As part of the cooperation, both will also continue to enhance the transformational potential of PEM electrolyzed water hydrogen production, accelerate the development of competitive PEM electrolyzed hydrogen products, and promote industrial applications and scenarios, drawing on projects like Japan's large H2 energy system to inform deployment. Moreover, they will continue to carry out in-depth cooperation across the entire hydrogen energy industry chain to accelerate overall industrialization.

Hydrogen energy boasts the biggest potential of all the current forms of clean energy, and the key to its development lies in its production. At present, hydrogen production primarily stems from fossil fuels, industrial by-product hydrogen recovery and purification, and production by water electrolysis. These processes result in significant carbon emissions. The rapid development of PEM water electrolysis equipment worldwide in recent years has enabled current technologies to achieve zero carbon emissions, effectively realizing green, clean hydrogen. This breakthrough will be instrumental in helping China achieve its carbon peak and carbon-neutrality goals.

The market potential for hydrogen production from electrolyzed water is therefore massive. Forecasts indicate that, by 2050, hydrogen energy will account for approximately 10% of China's energy market, with demand reaching 60 million tons and annual output value exceeding RMB 10 trillion. The Hydrogen: Tracking Energy Integration report released by the International Energy Agency in June 2020 notes that the number of global electrolysis hydrogen production projects and installed capacity have both increased significantly, with output skyrocketing from 1 MW in 2010 to more than 25 MW in 2019. Much of the excitement comes from hydrogen's potential to join the ranks of natural gas as an energy resource that plays a pivotal role in international trade, as seen in Germany's call for hydrogen-ready power plants shaping future power systems, with the possibility of even replacing it one day. In PwC's 2020 The Dawn of Green Hydrogen report, the advisory predicts that experimental hydrogen will reach 530 million tons by mid-century.

Shanghai Electric set its focus on hydrogen energy years ago, given its major potential for growth as one of the new energy technologies of the future and, in particular, its ability to power new energy vehicles. In 2016, the Central Research Institute of Shanghai Electric began to invest in R&D for key fuel cell systems and stack technologies. In 2020, Shanghai Electric's independently-developed fuel cell engine, which boasts a power capacity of 66 kW and can start in cold temperature environments of as low as -30°C, passed the inspection test of the National Motor Vehicle Product Quality Inspection Center. It adopts Shanghai Electric's proprietary hydrogen circulation system, which delivers strong power and impressive endurance, with the potential to replace gasoline and diesel engines in commercial vehicles.

As the technology matures, hydrogen has entered a stage of accelerated industrialization, with international moves such as Egypt's hydrogen MoU with Eni signaling broader momentum. Shanghai Electric is leveraging the opportunities to propel its development and the green energy transformation. As part of these efforts, Shanghai Electric established a Hydrogen Energy Division in 2020 to further accelerate the development and bring about a new era of green, clean energy.

As one of the largest energy equipment manufacturing companies in China, Shanghai Electric, with its capability for project development, marketing, investment and financing and engineering, procurement and construction (EPC), continues to accelerate the development and innovation of new energy. The Company has a synergistic foundation and resource advantages across the industrial chain from upstream power generation, including China's nuclear energy development efforts, to downstream chemical metallurgy. The combined elements will accelerate the pace of Shanghai Electric's entry into the field of hydrogen production.

Currently, Shanghai Electric has deployed a number of leading green hydrogen integrated energy industry demonstration projects in Ningdong Base, one of China's four modern coal chemical industry demonstration zones. Among them, the Ningdong Energy Base "source-grid-load-storage-hydrogen" project integrates renewable energy generation, energy storage, hydrogen production from electrolysis, and the entire industrial chain of green chemical/metallurgy, where applications like green steel production in Germany illustrate heavy-industry decarbonization.

In December 2020, Shanghai Electric inked a cooperation agreement to develop a "source-grid-load-storage-hydrogen" energy project in Otog Front Banner, Inner Mongolia. Equipped with large-scale electrochemical energy storage and technologies such as compressed air energy storage options, the project will build a massive new energy power generation base and help the region to achieve efficient cold, heat, electricity, steam and hydrogen energy supply.

U.S. Solar-Plus-Storage Growth 2021-2024 highlights rising battery storage co-location with solar PV, grid flexibility, RTO/ISO market signals, and ITC incentives, enabling peak shaving, firming renewable output, and reliable night-time power.

Key Points

Summary of U.S. plans pairing battery storage with solar PV, guided by RTO/ISO markets, grid needs, and ITC policy.

✅ 9.4 GW (63%) co-located with solar PV by 2024

✅ 97% of standalone capacity sited in RTO/ISO regions

✅ ITC improves project economics and grid services revenue

Of the 14.5 gigawatts (GW) of battery storage power capacity planned to come online amid anticipated growth in solar and storage in the United States from 2021 to 2024, 9.4 GW (63%) will be co-located with a solar photovoltaic (PV) solar-plus-storage power plant, based on data reported to us and published in our Annual Electric Generator Report. Another 1.3 GW of battery storage will be co-located at sites with wind turbines or fossil fuel-fired generators, such as natural gas-fired plants. The remaining 4.0 GW of planned battery storage will be located at standalone sites.

Historically, most U.S. battery systems have been located at standalone sites. Of the 1.5 GW of operating battery storage capacity in the United States at the end of 2020, 71% was standalone, and 29% was located onsite with other power generators.

Most standalone battery energy storage sites have been planned or built in power markets that are governed by regional transmission organizations (RTOs) and independent system operators (ISOs). RTOs and ISOs can enforce standard market rules that lay out clear revenue streams for energy storage projects in their regions, which promotes the deployment of battery storage systems. Of the utility-scale pipeline battery systems announced to come online from 2021 to 2024, 97% of the standalone battery capacity and 60% of the co-located battery capacity are in RTO/ISO regions.

Over 90% of the planned battery storage capacity outside of RTO and ISO regions will be co-located with a solar PV plant. At some solar PV co-located plants, the batteries can charge directly from the onsite solar generator when electricity demand and prices are low. They can then discharge electricity to the grid when peak demand is higher or when solar generation is unavailable, such as at night.

Although factors such as cloud cover can affect solar generation output, solar generators, now the number three renewable source in the U.S., in particular can effectively pair with battery storage because of their relatively regular daily generation patterns. This predictability works well with battery systems because battery systems are limited in how long they can discharge their power capacity before needing to recharge. If paired with a wind turbine, for example, a battery system could go days before having the opportunity to fully recharge.

Another advantage of pairing batteries with renewable generators is the ability to take advantage of tax incentives such as the Investment Tax Credit (ITC), which is available for solar projects, and other favorable government plans supporting deployment.
