Drawing on available evidence, this chapter traces the chain from upstream nickel supply for lithium-ion batteries through North American cell manufacturing buildout to innovations in system-level integration. Coverage does not include lithium, cobalt, or graphite mining; downstream project deployment; recycling; or financial details. Key Takeaways BHP’s Nickel West operation supplies battery-grade nickel sulfate at a scale of 100,000 t/yr, with 85–90 % of sales directed to battery markets, underpinning a critical raw material link for ESS manufacturers. At least four major North American manufacturing initiatives (Tesla, Honda‑LG ES, Ultium Cells, Peak Energy) are building or retooling ESS cell production, diversifying beyond lithium‑ion to sodium‑ion. Joint ventures (Honda‑LG, Ultium) are repurposing EV battery lines for ESS, reducing capital outlay and accelerating capacity. Tesla’s Lathrop Megafactory (40 GWh/yr) is currently the largest utility‑scale ESS production site in North America. New integration partnerships (Dukosi‑A123‑Nuvation Energy) are demonstrating chip‑on‑cell monitoring that could improve BESS safety and modularity. Upstream Nickel Supply for Battery Manufacturing Nickel is a critical input for many lithium‑ion battery chemistries used in stationary storage. BHP’s Nickel West operation in Western Australia represents a fully integrated mining‑to‑refinery value chain. The operation includes open‑cut and underground mines, concentrators, a smelter at Kalgoorlie, and the Kwinana refinery, which produces nickel metal as powder or briquettes and, since 2021, nickel sulfate through a dedicated plant. BHP’s Kwinana nickel sulfate plant has a stage‑one design capacity of 100,000 tonnes per year, enough to supply about 700,000 EV batteries annually. The company reported that 85 % of Nickel West’s existing sales – mainly nickel powder and briquettes – go to the battery market, and that share is expected to rise to around 90 % as the nickel sulfate plant ramps up. In fiscal year 2020–2021, Nickel West produced 89,000 tonnes of nickel metal. The facility exports nickel sulfate from the Port of Fremantle to global battery markets, linking Western Australian mines directly to downstream cell manufacturers in Asia and North America. This upstream concentration gives BHP a significant role in supplying battery‑grade nickel to the ESS and EV industries, though the available evidence does not provide data on other nickel producers or comparative market shares. North American Cell Manufacturing Buildout for ESS A wave of production capacity for ESS cells is taking shape in North America, driven by joint ventures that retool EV lines, dedicated factories, and new technologies such as sodium‑ion. The table below summarises the major initiatives supported by available evidence.

Grid-scale project financing and public funding Large BESS projects are achieving financial close with debt and equity from institutional investors, while public grants fund demonstration projects for non-lithium technologies. The UK National Wealth Fund committed up to £200 million of equity into Fidra Energy to finance construction of two Battery and Energy Storage System assets: Thorpe Marsh at 1,400 MW and West Burton C at 500 MW. Thorpe Marsh will be the largest BESS asset in the UK with seven times the capacity of the current largest installation. Fidra was established by EIG, an experienced infrastructure investor, who supports the investment through EIG’s fund vehicle. This is part of a £389 million equity raise with an additional £632 million of debt from the private market. The two sites have a combined capacity of 1.9 GW, a major contribution toward the 16 GW required by 2030. The National Wealth Fund addresses what it describes as a critical equity gap in the BESS market, where many developers lack the capital to reach final investment decision. European BESS developer Giga Storage reached financial close on July 9, 2026, for its 700 MW / 2.8 GWh Green Turtle project in Belgium, with construction beginning in September and commissioning expected in 2028. A consortium of ten international banks—ABN AMRO, ING, Rabobank, Triodos Bank, Triodos Investment Management, a.s.r., Belfius, HCOB, Santander, and SMBC—provided €450 million in debt financing. The remaining portion of required financing is contributed as equity by InfraVia Capital Partners, the French majority owner of Giga Storage. At peak moments, the energy storage system can supply electricity equivalent to the daily consumption of approximately 385,000 households. The U.S. Department of Energy awarded $4.7 million for a long-duration energy storage demonstration that will install a 2 MWh Invinity Energy Systems Endurium Enterprise vanadium flow battery in a building-level microgrid on the Bad River Band of Lake Superior Chippewa reservation in Ashland, Wisconsin. The DOE awarded $3.6 million to Invinity, which supplies the battery, and $1.1 million to muGrid Analytics, which provides the microgrid controls. The demonstration, branded Project VITALITY, will provide demand charge management, peak shaving, and resilience. The U.S.-manufactured system is planned for delivery in 2027, with operational data shared into the DOE’s rapid operational validation initiative.

It includes large-format cell development, gigafactory production startups, BMS innovations (chip-on-cell, AI-enabled, modular), and commercial second-life grid services. Excluded are non-lithium electrochemical storage (except sodium‑nickel ZEBRA in one research example), flow batteries, mechanical storage, and thermal storage. Market size estimates are from a single web source and not independently verified. Key takeaways Chinese battery manufacturers are ramping production of 500 Ah+ LFP cells, with CATL, EVE Energy, and HiTHIUM achieving first deliveries in 2025; Intertek CEA projects these cells could reduce BESS system costs through 2027 despite rising lithium prices. North American and Indian ESS battery production capacity is rapidly expanding: Ultium Cells (TN) and Honda‑LG ES (OH) started LFP cell production in July 2026 via converted EV lines, while iNVERGY commissioned a 3 GWh BESS factory in India with AI‑based BMS. Second‑life EV batteries are commercially viable for grid services; B2U deployed 24 MWh in ERCOT at under $100/kWh, compared to approximately $149/kWh for new Li‑ion systems, with plans to scale to 100 MWh in Texas. BMS technology is advancing with chip‑on‑cell monitoring (Dukosi DKCMS) enabling safer, scalable designs for large‑format cells, and modular BMS solutions are being validated for second‑life sodium‑nickel batteries. The combination of large‑format cell cost reductions, new regional production hubs, and second‑life pathways is diversifying the supply chain and lowering barriers for stationary storage adoption. Assumptions and limitations: All claims are based on company announcements or news articles from 2025‑2026; actual production volumes, costs, and performance may differ. Large‑format cell performance data are manufacturer claims and not independently verified. Cost projections (Intertek CEA) are based on modeling. Second‑life battery degradation over extended service life is not covered. Geographic coverage is limited to China, North America, and India. Large‑Format LFP Cells: The Race to 500 Ah+ large format lfp cell specifications Chinese battery manufacturers have accelerated the rollout of lithium iron phosphate (LFP) cells beyond the 314 Ah generation, positioning 500 Ah+ formats as a near‑term pathway to reduce balance‑of‑system (BOS) complexity and lift container‑level energy density. CATL is promoting a 587 Ah cell with a claimed volumetric energy density of 434 Wh/L and cycle life exceeding 10,000 cycles. First deliveries occurred in June 2025, and the company has installed four production lines at its Jining facility with an annual capacity of 60 GWh. EVE Energy has pushed its Mr. Big 628 Ah product line into the market, reaching mass production and shipment milestones in December 2024 at its Jingmen base. HiTHIUM follows a two‑track approach: a 587 Ah cell (first deliveries August 2025) and a larger 1,175 Ah cell that entered mass production in June 2025. According to research firm Intertek CEA, wider adoption of 587 Ah cells is likely to reduce BESS costs through 2027 even as lithium carbonate prices have roughly tripled. The cell‑level energy density gain is modest (roughly 20 %), but modules and racks designed around the new architecture achieve a 60‑80 % increase in energy density at that level, cutting BOS costs by reducing upstream component count. Critically, LFP cells account for only about 18 % of total BESS system cost, and lithium carbonate contributes roughly 10‑12 % of that total – smaller than the combined savings from upstream simplification.

North American and Indian Gigafactory Buildout New LFP battery production capacity for stationary storage is coming online from both converted EV lines and greenfield facilities. In the United States, Ultium Cells – the joint venture between LG Energy Solution and General Motors – began producing LFP cells for ESS at its Tennessee plant on July 7, 2026. The company invested approximately $70 million to convert part of its EV battery line, completing the conversion in less than five months. The cells are supplied to Vertech, LG Energy Solution’s North American ESS system integrator, for grid, renewable energy, and AI data‑center applications. The Tennessee plant meets U.S.-made manufacturing requirements under the Inflation Reduction Act. Similarly, the L‑H Battery Company (Honda‑LG ES) commenced lithium‑ion cell production at its Jeffersonville, Ohio plant in July 2026. Originally conceived for EV batteries, the facility redirected initial production toward stationary ESS due to the U.S. BEV policy shift. The plant maintains a flexible portfolio, also producing hybrid‑EV cells. First cells will be integrated into ESS solutions by LG ES Vertech, targeting residential, commercial‑industrial, and utility‑scale projects. In India, iNVERGY commissioned a 3 GWh BESS gigafactory in Dasna, Uttar Pradesh, in June 2026. The 217,000 sq ft fully automated plant – built with an investment of over ₹200 crore (~$25 million) – manufactures LiFePO₄ battery packs, complete BESS units (5 kWh to 5 MWh), and solar inverters for residential, C&I, and utility applications. The factory incorporates AI‑driven battery management systems, IoT‑enabled remote monitoring, and automated quality control. iNVERGY’s parent company reported consolidated revenue growth of 69 % in FY2025‑26, underlining the market pull for localized production.

Dukosi provided its DKCMS chip‑on‑cell monitoring system for a proof‑of‑concept BESS platform with A123 Systems and Nuvation Energy. The 1P13S module integrates A123’s 587 Ah LFP prismatic cells with Dukosi’s contactless cell monitoring and Nuvation’s L2 BMS, creating a highly scalable, safer architecture aimed at the North American market. The platform demonstrates how chip‑on‑cell technology can simplify wiring, improve safety, and enable more accurate state‑of‑charge tracking. Separately, researchers designed and experimentally validated a modular BMS for second‑life ZEBRA (sodium‑nickel) batteries retired from electric vehicles. The system includes string‑level modularity, thermal control, Coulomb‑counting SoC estimation, and hybrid state‑of‑health assessment. Integrated into a PV‑grid hybrid bench, it delivered 819 Wh in backup mode (500 W load for 1 h 38 min) and 1,424 Wh in self‑consumption mode (average 442 W for 3 h 13 min). The validation confirms the feasibility of repurposing sodium‑nickel cells for low‑ to medium‑power stationary applications such as residential backup and microgrids, extending service life and deferring recycling. iNVERGY’s Indian gigafactory further illustrates the deployment of AI‑based BMS and IoT‑enabled remote monitoring at production scale, embedding intelligence directly into the manufactured BESS units. Second‑Life Batteries in Grid Services Second‑life EV batteries are being deployed commercially for grid services. B2U Storage Solutions put a 24 MWh facility online east of San Antonio, Texas, in early 2026, using 500 reconditioned battery modules from retired General Motors electric vehicles. The site interconnects to CPS Energy’s distribution system and participates in the ERCOT day‑ahead energy market and ancillary services programs. The installation cost was under $100/kWh, compared to approximately $149/kWh for new lithium‑ion systems (BloombergNEF Q4 2025). The system charges during midday solar and wind surplus and discharges during peak periods, capturing energy‑arbitrage value. B2U plans three additional Texas locations to reach 100 MWh of total second‑life capacity. The company’s system is brand‑agnostic, accepting Nissan, Honda, Tesla, and Ford modules. Texas is projected to account for 53 % of all new U.S. battery storage capacity additions in 2026, and earlier deployments (e.g., Element Energy’s 900‑battery ERCOT project in 2025) demonstrate growing traction. The second‑life pathway offers a low‑cost complement to new BESS, leveraging retired automotive packs that still retain significant usable capacity for stationary duty cycles. ## Market Risk Risk Analysis The scope of this chapter is operational, regulatory, and financial risks for stationary energy storage systems (BESS) with a primary focus on the North American market, covering material supply chains, power electronics availability, trade policy, and project-level safety and interconnection risks from 2025 through 2027. Upstream markets considered include lithium, cobalt, nickel, graphite mining, battery cell manufacturing, and power electronics manufacturing. Excluded are downstream risks such as recycling, second-life battery markets, and insurance dynamics due to limited evidence in the supplied packet. The analysis relies on publicly available sources from 2024–2026; no primary market data or proprietary risk models were used. Key takeaways Over 70% of global cobalt supply originates from the DRC, where an administrative export‑quota glitch in 2026 threatened 20,000 tonnes worth $1.1 billion, driving a 160% price surge. Power electronics (IGBT/SiC modules) face an >18% demand‑versus‑capacity gap, extending lead times beyond 30 weeks and creating bottlenecks for inverter supplies. Uncertified BESS installations continue to pose fire risks, as demonstrated by the Warwick, NY fire, which involved an unauthorised system without a Certificate of Compliance. US tariff expansions under Section 232 and AD/CVD investigations add material cost uncertainty, with border detentions and forced‑labour scrutiny further complicating procurement. Interconnection cost swings of up to $27 million can render projects financially unviable, as seen in the Shoreham Long Island project with a total budget of $86 million. Raw Material Exposure and Geopolitical Supply Risk three risk categories stationary energy storage 2025-2027 Four critical battery materials—cobalt, nickel, graphite, and lithium—face distinct but compounding supply risks that directly affect stationary storage cell costs and project timelines. The concentration of cobalt in the Democratic Republic of Congo (DRC) remains the most concentrated single‑country risk. Congo produces about 70% of the world’s cobalt and hosts operations by CMOC, Glencore, Eurasian Resources Group, and Huayou Cobalt. In July 2026, an administrative glitch in the customs platform threatened export quotas. The regulator ARECOMS set a July 5 deadline for first‑half quota usage; unused volumes would be withdrawn and reallocated. Industry sources estimated that 60% to 75% of companies were unlikely to meet the deadline, risking as much as 20,000 metric tons of missed shipments worth $1.1 billion at current prices. The same regulator imposed a 96,600 t annual export cap for 2026 and 2027. Cobalt prices have surged 160% since February 2025 to $26/lb ($57,320 /t). This disruption directly raises costs for battery cell manufacturers and stationary storage developers who rely on cobalt‑based chemistries. These events underscore DRC cobalt mining instability as a persistent risk to stationary storage supply chains, directly threatening cobalt supply for stationary storage batteries. Nickel supply faces a different mechanism: oversupply‑driven mine suspensions that shrink available output. BHP suspended its Nickel West operations in Western Australia from October 2024, citing a global oversupply of nickel driven by Indonesia and a shift away from nickel in some battery types. The suspension caused an underlying EBITDA loss of approximately US$300 million. BHP intends to review the decision by February 2027 and continues to invest about A$450 million per year in the facilities to enable a potential restart. While near‑term nickel prices remain low, the suspension removes a significant source of Class 1 nickel used in high‑energy‑density batteries, potentially tightening supply if demand rebounds or if other producers follow. Graphite supply has been disrupted by operational and market conditions at the Balama mine in Mozambique, operated by Syrah Resources. Production was suspended for nearly a year due to post‑election violence and resettlement grievances. Production recommenced on 16 June 2025, with 7 kt produced in the following two weeks. By the end of the June 2025 quarter, 1 kt of natural graphite had been sold and shipped at a weighted average price of US$779 per tonne (CIF). The mine’s restart was achieved on time and within budget, but the prolonged suspension demonstrated the vulnerability of graphite supply to social and political disruptions in a single region. Lithium extraction in Chile faces ongoing water rights disputes and community opposition. SQM’s operations at Salar de Atacama are central to these tensions. Indigenous communities are demanding more control and environmental protections in negotiations with Codelco and SQM. A governance plan is under negotiation, expected to conclude by end‑2025. Any disruption to SQM’s extraction could affect lithium supply for battery cell production, though the negotiations have not yet resulted in production cuts. Material supply risk comparison Material Supply concentration Disruption type Price impact / financial magnitude Cobalt ~70% in DRC Administrative export quota glitch 160% price surge (Feb 2025 – Jul 2026); $1.1B at risk on 20,000 t Nickel Moderate (Indonesia dominant, but BHP key Western producer) Mine suspension due to oversupply EBITDA loss ~$300M; $450M/yr upkeep for potential restart Graphite High (Mozambique significant; Balama key) Production suspension (social/political) 7 kt output resumed; $779/t weighted average sale price Lithium Chile ~30% of global Ongoing water rights disputes and community opposition No direct price impact yet; potential production disruption if negotiations fail Component and Trade Policy Risk Beyond raw materials, power electronics are a critical bottleneck for stationary storage inverters. IGBT and silicon carbide (SiC) modules face a demand‑versus‑foundry‑capacity gap of over 18% in 2026, according to a BloombergNEF report cited by SupplyICs. Foundries are struggling to yield high‑quality 200 mm SiC wafers, creating persistent bottlenecks for brands such as Infineon, ON Semiconductor, and Wolfspeed. Lead times for IGBT modules reach 30–45 weeks in Q2 2026. In one case, a manufacturer of solar inverters saw their ON Semiconductor IGBT module allocation pushed out by an additional 15 weeks, threatening a factory shutdown in Eastern Europe. These delays directly affect stationary storage system integrators who depend on inverters for grid‑connected projects, extending project commissioning timelines and raising procurement costs. Trade policy amplifies component risk. A Morgan Lewis 2026 outlook identifies tariffs and trade enforcement as core risk variables. US tariff expansion, Section 232 investigations into steel, aluminum, copper, and critical minerals, and AD/CVD investigations targeting battery materials are reshaping procurement strategies. Border detentions related to forced‑labour scrutiny remain a significant supply chain risk. Although finished battery storage systems may be excluded from some tariffs, upstream inputs like steel enclosures, copper wiring, and power modules are affected. Developers face cost uncertainty from tariff volatility, requiring early procurement strategies and contractual risk allocation (fixed pricing, pass‑through clauses, renegotiation mechanisms). The combination of extended lead times and tariff‑driven cost increases makes project budget certainty challenging for developers seeking financing. Project-Level and Regulatory Risk Individual projects face operational safety and regulatory compliance risks that can derail timelines and increase costs. A December 2025 fire at the Church Street Battery Storage Facility in Warwick, New York, involved an unauthorised system. Village Mayor Michael Newhard confirmed that the system was activated and fully charged without a required Certificate of Compliance, and that the facility “should not have been operational.” Water infiltration was identified as the probable cause; similar failures occurred at two other Convergent‑operated sites in 2023 after heavy rain. The fire was contained to one unit with no injuries, but cleanup, testing, engineering, and police service costs must be borne by the owner. This incident highlights the risk of uncertified installations—specifically the lack of UL or regulatory certification—and intensifies scrutiny on developers and regulatory compliance regimes. Grid interconnection costs pose another project‑level financial risk. The proposed Shoreham battery project on Long Island—a 50‑MW facility at the former Shoreham nuclear plant site—faces estimated connection costs ranging from $0 to $27 million, according to a draft NYISO report. The project has a total budget of $86 million and has applied for tax breaks of up to $6.4 million from the Brookhaven Industrial Development Agency. Developer Key Capture Energy (KCE) has indicated that the uncertainty could render the project financially unfeasible. The cost variability stems from grid upgrade requirements that are difficult to predict before final engineering studies. While KCE is seeking an extension, the case illustrates how interconnection cost swings of nearly one‑third of total project budget can threaten viability. Comparing project risk profiles: the Warwick fire represents a safety‑compliance risk that can be mitigated by stricter enforcement of certification requirements and inspection protocols. The Shoreham interconnection cost issue is a financial‑infrastructure risk that depends on utility and ISO procedures. Both can delay or halt projects, but the mechanisms differ: Warwick exposes liability and reputational damage, while Shoreham exposes budget overruns and financing challenges. Summarize the three risk categories with key metrics: 70% cobalt concentration, 18% supply gap for SiC modules, $27 million interconnection cost uncertainty, and the Warwick fire as a regulatory safety incident. Surviving risk claims and their selected evidence. Risk mechanism, exposure, geography, timing, and conditionality. Assumptions and limitations: This analysis relies on publicly available sources from 2024–2026. No primary market data or proprietary risk models were used. The market size of $64.54 billion is a single web estimate and is indicative. Coverage excludes recycling, second-life battery markets, insurance dynamics, and grid interconnection delays beyond the Shoreham example due to limited evidence. No quantitative risk probability or severity scoring is available for material disruptions. ## Regulatory Landscape Stationary Energy Storage Systems Regulation Stationary energy storage regulation in 2024–2026 is undergoing simultaneous tightening across fire safety, grid interconnection, and end-of-life sustainability, forcing project developers and manufacturers to navigate a multi-jurisdictional compliance environment that varies significantly between the US and EU. The market, estimated at $64.54 billion in 2025, is shaped by federal and state-level rules in the United States and by European Union-wide requirements that affect global supply chains. Key takeaways Fire safety regulations (NFPA 855 2026, UL 9540A 6th ed) are tightening with comprehensive updates that include new battery technologies (flow batteries), new installation contexts (barges), and consolidated general requirements, directly affecting system integrators and residential installers. FERC Order 841 has opened wholesale markets to storage resources down to 100 kW, but implementation varies by RTO/ISO; California’s CPUC Rule 21 continues to evolve for DER interconnection, with a new rulemaking in 2025. EPA RCRA classifies most spent lithium-ion batteries as hazardous waste, pushing generators toward universal waste management; the EU Battery Regulation introduces mandatory carbon footprint declarations for industrial batteries >2 kWh and recycled content targets from 2028. Regulatory divergence between the US (emphasis on fire safety and grid interconnection) and the EU (emphasis on sustainability and recycled content) creates different compliance burdens for global manufacturers and battery cell producers. Recent 2024–2026 updates (IFC 2024, NFPA 855 2026, UL 9540A 2026) require project developers to reassess installation designs and testing protocols, with potential impacts on project timelines and costs. Show supported rules, jurisdictions, affected participants, dates, and requirements. Surviving regulation claims and their selected evidence. Instrument, jurisdiction, effective timing, obligation, and market consequence. Fire safety and installation standards The 2026 editions of two foundational US fire safety standards—NFPA 855 and UL 9540A—introduce material changes that affect system integrators, residential installers, EPC contractors, and equipment manufacturers. These updates converge with the 2024 edition of the International Fire Code (IFC) Chapter 12 to create a denser compliance environment for stationary storage installations. NFPA 855, the Standard for the Installation of Stationary Energy Storage Systems, has been significantly revised in its 2026 edition. General requirements applicable to all energy storage systems have been consolidated into Chapter 4, while technology-specific requirements are now contained in dedicated chapters. The standard adds new battery types, introduces Chapter 16 for flow batteries, and Chapter 17 for ESS on barges. Refined exclusions apply to lead-acid, aqueous nickel-based, and aqueous metal-air batteries. New requirements for an emergency response plan and for EV charging systems that have energy storage are also included. These revisions directly impact system design and siting decisions for project developers and require updated fire protection planning from EPC contractors. UL 9540A, the Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems, was published as a new Sixth Edition on March 13, 2026. The edition revises Installation Level Testing requirements for large-scale fire testing. A notable change allows Unit Level testing to be skipped if Installation Level testing is conducted, potentially reducing testing burdens for manufacturers opting for the larger-scale test route. The standard is ANSI and SCC approved. For system integrators and battery cell manufacturers, the revised test methodology may alter product certification strategies and timelines for new battery chemistries and large-format systems. The International Fire Code (IFC) 2024 edition includes Chapter 12 on energy systems, providing an additional code-based compliance pathway. Gaps between IFC Chapter 12 and NFPA 855 persist, as the IFC is an adoptable model code while NFPA 855 is an installation standard; adopters of the IFC may need to reference NFPA 855 for detailed testing and fire suppression criteria. For residential solar installers and commercial project developers, the interplay between these documents determines local permitting requirements and fire marshal approvals.

FERC Order 841, Order 2006, and California’s CPUC Rule 21 create overlapping but distinct requirements for different project scales and geographies. FERC Order 841 requires each Regional Transmission Organization and Independent System Operator to revise its tariff to establish a participation model for electric storage resources. The model must ensure that storage resources are eligible to provide all capacity, energy, and ancillary services they are technically capable of providing, can be dispatched, and can set the wholesale market clearing price as both a seller and buyer. A minimum size requirement must not exceed 100 kW. This order removes historical barriers that treated storage like traditional generation and enables smaller projects to participate in RTO/ISO markets, affecting project developers and battery cell manufacturers targeting wholesale market revenue streams. FERC Order 2006 establishes standard interconnection procedures and agreements for small generators up to 20 MW. Public utilities that own, control, or operate transmission facilities must amend their open access transmission tariffs to include these standardized procedures. The order applies to interconnection service for devices used for electricity production with capacity of no more than 20 MW, with an effective date 60 days after publication in the Federal Register. This rule provides a streamlined pathway for medium-scale storage projects that fall below the 20 MW threshold, reducing interconnection timelines and costs for project developers and EPC contractors. California’s CPUC Rule 21 governs interconnection of distributed energy resources, including residential stationary storage, to the electric distribution systems of Pacific Gas and Electric, Southern California Edison, San Diego Gas & Electric, and small/multi-jurisdictional utilities. First adopted in 1982, Rule 21 has been refined through successive rulemakings. The Commission opened a new proceeding, R.25-08-004, in August 2025 to update interconnection procedures concerning safety, reliability, transparency, and cost containment. The prior proceeding R.17-07-007 was closed by Decision D.24-12-034 in December 2024. For residential solar installers and DER storage providers, Rule 21 defines technical interconnection requirements, metering standards, and application processes that directly affect project feasibility and timelines in the California market.

In the United States, the Environmental Protection Agency under the Resource Conservation and Recovery Act classifies most lithium-ion batteries as hazardous waste when disposed of, due to ignitability and reactivity characteristics (D001 and D003). Generators of spent lithium batteries are responsible for determining whether their waste is hazardous and must manage it accordingly. To streamline compliance, the EPA recommends that businesses manage all used lithium batteries as universal waste under 40 CFR Part 273, which provides reduced handling requirements compared to full hazardous waste management. The universal waste pathway allows collection, transportation, and recycling under simplified standards until the batteries reach a destination facility. For stationary storage owners, this classification imposes recordkeeping, labeling, and time limits on storage, while the universal waste option reduces administrative burden. Battery recycling services benefit from the clearer regulatory pathway established by the EPA’s guidance. In the European Union, Regulation 2023/1542 (the EU Battery Regulation) establishes sustainability requirements for batteries placed on the Union market. Article 7 requires a carbon footprint declaration for rechargeable industrial batteries with a capacity greater than 2 kWh, including stationary battery energy storage systems defined as industrial batteries designed to store and deliver electric energy to the grid or to end-users. The declaration must be drawn up for each battery model per manufacturing plant and follow implementing acts establishing the format. Article 8 introduces recycled content requirements that apply from 18 August 2028 or 24 months after the date of entry into force of the relevant implementing act. For global manufacturers supplying both US and EU markets, these requirements create divergent compliance paths: EU-facing products must track and declare carbon footprint and recycled content, while US-facing products must navigate RCRA hazardous waste classification and universal waste management options. Battery cell manufacturers and system integrators serving both jurisdictions face dual reporting and design-for-recycling obligations that increase compliance costs.
