A U.S. district court must rule on federal antitrust claims made by four plaintiffs against Arizona utility SRP’s anti-solar rate, and must consider “injunctive relief” that could immediately halt the anti-solar rate. February 2, 2022 William DriscollFour customers suing Arizona utility Salt River Project (SRP) over its anti-solar rate “adequately allege antitrust injury,” said the U.S. Ninth Circuit Court of Appeals in a ruling on Monday. Now the U.S. district court that had originally dismissed the lawsuit must take up the case anew, which could result in an end to the anti-solar rate.Halting the anti-solar rate could revive the rooftop solar market in the Phoenix area, where SRP serves about one million households.Four SRP customers with rooftop solar had sued the utility in federal district court after their bills went up an average of $600 a year, which they claimed unlawfully discriminated against customers who added rooftop solar. When the district court dismissed the case, the four plaintiffs appealed.“Applications for solar-energy systems in SRP territory decreased by between 50 and 96 percent” after the anti-solar rate went into effect in 2015, the appeals court noted.If the district court grants injunctive relief on the plaintiffs’ federal antitrust claims, that could mean halting the discriminatory rate structure immediately, “which could have the effect of allowing rooftop solar to flourish in SRP territory,” said Jean Su, an attorney and director of the Center for Biological Diversity’s Energy Justice Program. The Center had filed a “friend of the court” brief in the case along with four other groups.Because SRP was established as an agricultural improvement district and is thus a subdivision of the state, the appeals court ruled that SRP is exempt from damage claims under antitrust law.The appeals court’s antitrust ruling hinges on two factors specific to SRP and Arizona. First, SRP does not file its rates with a regulatory agency for approval, so the “filed rate doctrine” that “prohibits individuals from asserting civil antitrust challenges to an entity’s agency-approved rates,” did not apply, the court said.Second, Arizona law promotes competition in the retail electricity market, the appeals court found. If Arizona law instead aimed to displace such competition, the court said that SRP, as a political subdivision of the State of Arizona, could be entitled to “state-action immunity.”Su explained that although anti-solar rates that gain approval from state-appointed utility commissions “are largely protected from antitrust claims, under both the file-rate doctrine and state-action immunity defenses,” other public power providers like SRP “may not be able to use those defenses, particularly if the anti-solar rates contradict state policy as was the case for SRP.”The appeals court also ordered the lower court to rule on plaintiffs’ federal equal protection claims, finding that those claims were filed on a timely basis.The appeals court upheld the lower court’s dismissal of plaintiffs’ claims under state law, as it found the plaintiffs did not meet Arizona’s notice-of-claim statute.The U.S. Department of Justice had also filed a “friend of the court” brief in the case.

France’s first high-voltage transmission grid-connected battery project colocated with a solar PV plant will be equipped with a battery energy storage system (BESS) from Saft.

The battery manufacturer and energy storage system integrator announced today the award of an engineering, procurement and construction (EPC) contract by renewable energy developer and independent power producer Neoen.

Saft will provide a modular, plug-and-play 8MW/8MWh BESS to Neoen’s solar PV project in Antugnac, southern France. The battery storage will perform frequency regulation ancillary services for the grid of national transmission operator RTE after Neoen won a seven-year contract through RTE’s AOLT tender process.

The France-headquartered battery storage provider, a subsidiary of TotalEnergies, will engineer, manufacture, construct and integrate the full BESS solution, based on four of Saft’s Intensium Max containerised units, along with power conversion system (PCS) equipment, controls and SCADA systems. 

Saft said the project will be delivered this Spring, within 10 months of contracts being signed. 

While Neoen has a strong background in the global wind and solar renewable energy markets, it is perhaps best known in the energy storage industry for its large-scale battery projects in Australia. 

These include — among others — the recently inaugurated Victorian Big Battery (300MW/450MWh) and the Hornsdale Power Reserve, which for a long time after commissioning in 2019 was the world’s biggest lithium-ion battery storage project. BESS supplier to both those projects was Tesla. 

Neoen’s French development director Guillaume Decaen said Saft was selected due to its “deep knowledge of battery technology and proven experience in energy storage globally, its ability to manage a complete EPC scope including civil works and grid connection requirements from project inception to end-of-life dismantling”.

Decaen also noted that the performance of the asset is guaranteed throughout its lifetime by Saft. Saft meanwhile said that although the initial and primary function of the BESS is frequency regulation, the asset will be flexible enough to be used for additional services over the next 15 years, optimising project revenues. 

In a recent webinar hosted in partnership with Energy-Storage.news, Saft’s energy storage team members including director of innovation Michael Lippert discussed the need for energy storage systems and their operators to be agile to meet the changing needs of the market, with digital technologies the key enabler of that agility. 

Recently, commissioning was completed on an expansion project for France’s largest standalone BESS project, a Saft system deployed at a TotalEnergies refinery site in Dunkirk. The project was expanded from 25MW/25MWh inaugurated in January 2021 to 61MW/61MW, unveiled in December last year. The project was also discussed in detail as part of the Saft webinar with Energy-Storage.news.

Saft said today that its contract with Neoen guarantees high availability and performance, claiming that the BESS will be adaptable to changing operating patterns and able to perform more than two full discharges daily. The company will also support the system remotely from its energy storage system operating hub in Bordeaux, France, one of three such centres it has around the world. 

The majority of battery systems paired with solar PV in France have been on the European country’s various island territories around the world, for which annual capacity tenders have been conducted for a few years.

California’s energy transition will need 53GW of solar PV by 2045, with the state’s transmission system requiring a US$30.5 billion investment alongside major increases in energy storage to accommodate the extra power.  

A draft version of California ISO’s (CAISO) 20-Year Transmission Outlook report providing a roadmap for the next two decades and a draft 2021-2022 Transmission Plan covering the next 10 years, was issued today. 

It outlined that by 2045, the state would require 53GW of utility-scale solar, 37GW of battery energy storage systems (BESS), 4GW of long-duration storage and more than 2GW of geothermal, alongside 24GW of wind power reserves, all of which need to be connected to the grid.

Created in collaboration with the regulatory California Public Utilities Commission (CPUC) and the state government’s California Energy Commission, the draft plan will be voted on in March by CAISO’s Board of Governors.

Microsoft, Google and 10 other companies have joined the Long Duration Energy Storage (LDES) Council, a CEO-led organisation launched at COP26 in November to push for the global deployment of technologies that can store and discharge energy for eight hours or longer.

Along with Danish energy company Ørsted, the tech giants are among five new ‘anchor’ members, bringing the total to 13. These comprise a mix of large conglomerates with interests in the renewable energy space, from Indian renewable energy giant Greenko to BP and Rio Tinto.

It has also welcomed seven new ‘technology’ members, companies focused on developing new forms of long duration energy storage, bringing the total to 23.

New technology members include heavy industrial group Sumitomo SHI FW, flow battery company VoltStorage and nickel-hydrogen battery company EnerVenue.

The Council says that LDES has the potential to deploy 1.5-2.5 TW power capacity globally by 2040: 8-15 times the total storage capacity deployed today. LDES could deliver 85-140 TWh by that year which would mean the ability to store up to 10% of all electricity consumed and would account for over half of all installed power flexibility capacity. 

Achieving this, it says, will need investment of US$1.5-3 trillion — equal to the current global investment in Transmission & Distribution (T&D) infrastructure made every 2-4 years — and has set out a roadmap of how to get there.

It forecasts US$50bn cumulative investment by 2025 achieving 1 TWh of LDES; US$200-500bn by 2030 achieving 5-10 TWh; and $1.1-1.8bn by 2035 achieving 35-70 TWh before the 2040 target. It concedes that LDES costs must decrease by 60% for it to be cost optimal, but notes that even larger cost savings have been achieved in wind and solar.

Maud Texier, leading carbon-free energy activities at Google, commented that: “…we view long duration energy storage as a key pillar on the path to a carbon-free future”.

The Council’s modelling says the average system duration for LDES will increase over this period, with 24-hours-plus duration going from 40% of all TWh of cumulative installed energy capacity in 2030 to 80% by 2040. The average installed duration globally is expected to reach 14 hours by 2030 and a whopping 64 hours between 2030-2040. 

The US is expected to account for one-third of LDES capacity with Europe (including UK) and India around 10% each, and Japan the next-largest at around 3%, according to data from the Council’s knowledge partner McKinsey. It does not give a figure for China.

Minister of Finance Nirmala Sitharaman holds the budget’s iconic red cloth folder in 2021. Image: Gov’t of India Press Bureau.

The Indian government’s decision to classify grid-scale energy storage as infrastructure addresses the industry’s “biggest concerns” by making investments easier to facilitate, Energy-Storage.news has heard. 

As part of the Union Budget 2022-2023 speech and announcements yesterday by Minister of Finance Nirmala Sitharaman, energy storage and data centres were awarded the status. Minister Sitharaman said that this will “facilitate credit availability for digital infrastructure and clean energy storage”.

India’s banks and financial institutions have a standard, government-identified list to follow when it comes to choosing what qualifies for infrastructure loans, Ulka Kelkar, director of the climate programme at non-profit research group WRI India, told Energy-Storage.news. 

“This list includes five types of infrastructure, which are more in the nature of public goods than private goods,” Kelkar said, from energy, transport, communications, water & sanitation to social and commercial infrastructure. 

“Specifically adding grid-scale energy storage to this list should make it easier to access infrastructure credit.”

Kelkar explained that this showed the range of policy instruments a government can deploy is much wider than budgetary allocations and fiscal incentives like taxes or subsidies, but includes other forms of de-risking, from mandates and standards to procurement, aggregation, credit aggregations and more. 

The budget also included direct support for the upstream end of the clean energy value chain. As reported yesterday by our sister site PV Tech, an allocation of funding for solar PV manufacturing within the country through a scheme called the Production Linked Incentive (PLI) was quadrupled with an addition of Rs19,500 crore (US$2.6 billion).

There was also a commitment to establishing battery recycling and battery swap programmes for electric vehicles (EVs), while a separate Production Linked Incentive programme already in place for advanced chemistry battery cell manufacturing is ongoing, aimed at supporting 50GWh of domestic production capacity. 

India Energy Storage Alliance welcomes ‘progressive budget’

The India Energy Storage Alliance (IESA) told Energy-Storage.news it welcomed the “progressive budget,” which it said addressed many key requests from the industry and would make faster adoption of energy storage and e-mobility in India possible. 

“Infrastructure status for energy storage sector will address the biggest concerns of industry related to ease of financing,” IEAS president Dr Rahul Walawalkar said. 

“IESA believes that over the past decade energy storage technologies have made tremendous advancements in improving performance and reducing capital cost, so availability of financing was identified as the key hurdle for rapid adoption.”

Infrastructure status for energy storage had been among requests IESA had made to the Ministry of Finance, covering both manufacturing and deployment and Dr Walawalkar said.

“We are glad our submission was considered positively,” he said.

“As the Harmonised Master List of Infrastructure sub-sectors already includes Electricity Generation and Electricity Transmission, the inclusion of Energy Storage will help cover all the important segments of energy under the Infrastructure Status.” 

IESA also welcomed that increase in funding for solar PV manufacturing as a close ally sector of energy storage. According to Walawalkar, the Ministry of Finance can be expected to also consider increasing the 50GWh allocation for advanced chemistry cell (ACC) manufacturing support in the coming months. 

Applications for the ACC incentive had been oversubscribed, with a total of 130GWh of competing bids received and the Ministry may increase the targeted capacity “to ensure India can keep up with the global increase in advanced cell manufacturing,” the IESA president said. 

WRI India’s Kelkar said the PLI funding increase for solar could have a positive impact on energy storage adoption.  

The allocation specifically related to “manufacture of high efficiency modules, with priority to fully integrated manufacturing units from polysilicon to solar PV modules”.

However, Kelkar said, it might help reduce the combined cost of solar and storage for each unit of electricity generated, even though the scheme itself may not directly affect storage.

“With such schemes, the focus seems to be on nurturing the indigenous manufacturing industry, creating jobs, and driving down costs,” Kelkar told Energy-Storage.news. 

IESA also welcomed other measures announced, or referred to as under consideration by the government, that could have a positive impact on India’s energy storage manufacturing and supply chain.

For example, while the budget broadly emphasised support for domestically-made goods and included duties on imported products, reforms on customs and duties rates for raw materials that are being discussed could ease supply chain constraints and support domestic makers, Dr Walawalkar said. 

A concessional 15% tax rate for newly incorporated domestic manufacturers has been extended by a year from 31 March 2023 to 31 March 2024, which will help facilitate investments required in the next two years to get PLI-backed companies —as well as potential component suppliers — up and running. 

IESA also warmly welcomed measures to support start-ups, green energy sector job opportunities for young people and skills training in digital and other industry sectors and e-mobility. The group also said support for grid-connected microgrids was a positive step, helping boost agribusiness in remote areas.

The group did say, however, that a reduction in the General Sales Tax for EV batteries to 5% that is suggested had not been included in the budget, which IESA asked the Ministry of Finance to reconsider. 

The green hydrogen sector is also “missing in the budget,” Dr Walawalkar said. IESA has suggested the creation of a special fund for green hydrogen and PLI support for green hydrogen electrolyser manufacturing.

Nonetheless, the budget appears to have been well received. It follows the announcement a few days ago that India’s Ministry of Power has clarified the role and status of energy storage within the power sector, which again could accelerate adoption. 

The country already has over 150GW of renewable energy capacity installed and to reach its 2030 target of 500GW, will need about 28GW/108GWh of energy storage, the Central Electricity Authority has forecasted. 

Previous budget announcements covered by Energy-Storage.news in 2020 and 2021 were welcomed by IESA for their broad support of renewable energy and the green economy, but yesterday’s announcement appears to be the first instance of specific, directly supportive policy announcements pertaining to energy storage by Minister Sitharam.

Altus Power committed to a multi-year supply agreement with tier 1 North American PV module manufacturer Heliene, and invested $5 million in the company’s growth. February 1, 2022 Ryan KennedyAltus Power announced it signed an agreement with Heliene to purchase up to 250MW of solar modules for use in construction projects across the US. The deal includes a commitment by Altus Power to invest up to $5 million in Heliene in anticipation of the company’s initial public capital raise. Heliene is set to perform a reverse take-over transaction with Buzz Capital 2 Ltd. and join the TSX Venture Exchange.The Heliene 36 Cell Monocrystalline half-cut cell module. Image: Heliene Heliene manufactures its modules with monocrystalline PERC cells, which it said have a half-cut design to reduce cell-to-module losses. The panels have use cases in utility-scale, commercial & industrial, and residential markets.“Many U.S. solar developers are currently facing supply and trade volatility risks, causing potential project delays. We are pleased to partner with our customer Altus Power to help them develop the projects in their pipeline with confidence,” said Martin Pochtaruk, Heliene CEO.The modules are planned to be produced in Mountain Iron, Minnesota, where Heliene recently expanded its operations. Three production facility locations in the US and Canada are expected to achieve a total manufacturing capacity of 900MW in operations by Q3 2022. Heliene, founded in 2010, has facilities in Minnesota, Ontario, and Florida.“Domestic made equipment and materials are becoming an increasingly important component of our procurement efforts and this supply certainty will be significant to our total module requirements,” said Tony Savino, Co-Founder and Chief Construction Officer of Altus Power. Savino said Altus Power is the only public, vertically integrated commercial and industrial focused clean electrification company in the US. He said that having a reliable, steady supply of solar modules is critical to the company’s growth strategy. Based in Stamford, Connecticut, Altus Power owns and operates locally sited solar PV, energy storage, and EV charging infrastructure across 18 states.ManufacturingUS and North American solar manufacturing have potential to rise significantly as both Sen. Jon Ossoff’s Solar Energy Manufacturing for America Act and the Biden Administration’s Build Back Better (BBB) Act, which has $550 billion in climate provisions, work their way through the legislature. An earlier proposal of BBB had significant provisions for US manufacturing. Included in the bill were incentives for the manufacture of thin film PV or crystalline PV cells. The incentive would pay $0.04 per watt DC capacity of the cell. PV wafers would be offered $12 per square meter, and solar-grade polysilicon is offered $3 per kilogram US-made solar modules are offered an incentive of $0.07 per watt. Senator Joe Manchin (D-VA) shut down the earlier proposal of BBB, and said he intends to start “from scratch,” but it is likely that US manufacturing would continue to receive focus in the Act.This content is protected by copyright and may not be reused.

Addressing the threat posed by climate change will mean using massive amounts of clean energy resources like solar to both decarbonize and electrify the economy. While projects hundreds of megawatts in capacity and breakthrough battery tech steal a lot of the headlines, small-scale, distributed energy resources (DER) will be one of the pillars holding up the energy transition.Distributed generation and storage can help to keep communities powered during storms and outages, keep electricity costs low, and ensure the benefits of renewables reach all the members of a community. Community microgrids are increasingly being viewed as a necessity for future energy resiliency.Founded in 2019, Franklin Whole Home (FranklinWH) has been making waves to start 2022, with the company announcing the launch of its first residential storage system. The FranklinWH system integrates its lithium iron phosphate “aPower” battery with adaptive learning, which is part of the included aGate smart control system. Image: FranklinWH The 13.6KWh battery is compatible with any PV inverter technology, the company reports, and it can connect with existing solar systems while scaling up to 15 units for a total of 204KWh of capacity. In the event of a power failure, its black start feature creates a micro-grid for the home.One of the main points the company focused on in development of the system was ensuring ease of operating for the customer; breaking down the barrier many customers perceive to exist between them, and understanding and getting the most out of their home storage system.At Intersolar North America 2022, pv magazine was able to sit down with FranklinWH Chief Sales Officer Cheung “Gary” Lam to discuss the development process for his company’s first commercialized product, and FranklinWH’s vision for the future of distributed storage in the US.As Lam sees it, utilities currently value distributed storage only in aggregate use cases, like for demand response or peak demand shaving programs. He sees opportunity to shift this perspective, presenting the individual value of storage assets to both the consumer and the utilities at large.“What we are trying to do is make decentralized storage capable of working in a truly decentralized way, like in its own way.” Lam told pv magazine. “If [the system] is disconnected from the grid, we still have the safety and functionality to guarantee that someone’s home is  delivering power not only safely, but in a way that still allows them to live comfortably.”Value for the customerOn the customer side, the FranklinWH pitch, at first, is similar to many other residential storage solutions: the system provides backup power in the case of grid failure or weather-related outages, while also providing significant bill savings in typical, day-to-day operations. Where FranklinWH has developed the system to excel is in its ease of use and management.Within the system’s dedicated aGate smart control system, customers can configure their battery to automatically maximize their bill savings, by using electricity from the grid when it is cheapest and using stored or self-generated electricity when prices are higher. The system also includes weather forecasting, and can focus on charging the battery from a PV system before a storm rolls in.In outages, aGate’s adaptive-learning technology allows it to manage complex load scenarios, and the user can integrate three additional large loads such as HVAC, pool heating, or electric vehicle charging.According to Lam, the biggest impediment holding back the vast potential of distributed storage, is how difficult it can be to retrofit storage onto an existing PV system, a process made harder the older that the system in question is.This impediment was the second major focus when developing FranklinWH’s storage system.“Currently, it’s very complicated, most of the solutions out there are for DC coupling, and they have to tie [the battery] into your solar system.” Lam explained. “Compatibility then becomes a big issue. If you installed a system five years ago, you might have to rip up your entire system and re-install a new solar system just to be compatible with the battery you chose.”By using an AC architecture, FranklinWH was able to develop a standard 240 volt split-phase system that he attests any electrician could add to a home energy supply with no previous solar or storage installation experience.Getting utilities on boardTo anyone familiar with DERs the issue Lam sees as the biggest impediment to widespread DER adoption from a utility perspective is a tale as old as time: our grids aren’t capable of handling high-density DER penetration.Lam shares that, as well all know, the grids we still rely on, especially on the coasts, were developed over 100 years ago, designed with much lower power demands in mind. With the advent of HVAC systems and air conditioning becoming standard in almost every home, and the increasing proliferation of electric vehicles and their charging hardware, the grid is being stressed to the point of fault across the country.As would be expected of anybody in the DER space, Lam sees self-generation and self-consumption as the solution. If you take assets off the grid, or have them interact with each other independent of the grid, you relieve significant stress.And while utilities have, in general, been opposed to the widespread proliferation of DERs, due to the adverse effect those systems have on the utility’s traditional business model, widespread transmission and distribution grid upgrades are far more costly than the revenue lost by self-generation. Moreover, self-supply and stress reduction are not the only features of DER, and the full suite of grid-strengthening attributes the resources present has never been given a hard value.“Self-consumption will be the most effective way to go against this kind of challenge,” said Lam. Any energy you store is generated, stored, and consumed locally. You don’t occupy any transmission capacity, and the transmission utility is more like an ultimate backup for you. If anything fails, you still have your grid with you. And that’s like the ultimate safety.”This content is protected by copyright and may not be reused.
