Can Industrial & Commercial Energy Storage Lithium Battery Manufacturers Support Application Procedures for Energy Storage Projects?
2026-07-21
Complete Approval Procedures for Industrial & Commercial Energy Storage Projects & Common Difficulties Faced by Independent Applicants
In accordance with the Interim Measures for the Administration of New Energy Storage Projects and the detailed implementation rules for industrial and commercial energy storage released by provincial and municipal authorities across China in 2026, the full approval process for a complete industrial and commercial energy storage system from project initiation to grid connection includes five core stages, each with strict requirements for supporting documents, technical indicators and qualification certificates.
- Preliminary Site Survey and Feasibility Assessment:On-site data collection including factory power load, transformer capacity, floor load bearing capacity and power distribution layout is required, followed by energy storage revenue calculation reports and technical feasibility solutions, which serve as the fundamental documents for subsequent project filing.
- Project Filing with Development & Reform / Energy Administration Authorities (Mandatory Pre-Approval Step):Applicants shall register new energy storage projects via the official online investment approval platform. Mandatory submission materials include enterprise business licenses, site ownership certificates, complete technical specifications of energy storage systems, equipment qualification certificates and investment statements. Incomplete or non-compliant documents will result in direct rejection of filing applications.
- Grid Connection Application and Official Reply from Power Supply Bureaus:Grid connection documents must be submitted to local power authorities. After on-site inspection, power bureaus will issue formal grid access opinions. The battery management system (BMS), power converters and protection devices of energy storage equipment must fully comply with grid connection standards; projects with unqualified technical parameters cannot obtain official grid access approval.
- Special Supplementary Approvals (EIA, Fire Safety Assessment & Safety Evaluation):Energy storage projects with a capacity above 5MW are required to complete energy conservation assessment and environmental impact assessment. Energy storage containers and dedicated battery rooms need to pass fire protection design review. Third-party authoritative test reports covering Lithium Battery explosion-proof design, thermal runaway control and fire suppression systems are mandatory.
- Grid Acceptance upon Completion of Construction:The project can only be put into grid-connected operation after passing third-party CMA testing, equipment joint commissioning and on-site acceptance by power grid authorities. Full sets of product certifications, factory inspection reports and system debugging records are indispensable.
Three Major Difficulties for Enterprises Handling Approval Independently
First, insufficient supporting qualification documents. Most enterprises lack authoritative certification reports such as UN38.3, MSDS, UL and TUV for lithium batteries, leading to failure in filing and fire safety reviews. Second, mismatched technical solutions. Without professional knowledge of grid connection specifications, self-drafted electrical drawings and BMS control schemes often fail power bureau audits, requiring repeated revisions and delaying the whole schedule. Third, asymmetric policy and procedural information. Filing and grid connection standards vary greatly across different regions. Purchasing and administrative staff without industry experience have to travel between multiple government departments repeatedly, extending the project cycle by two to three months on average.
Tiered Capabilities of Energy Storage Lithium Battery Manufacturers in Supporting Approval Procedures
There is a huge gap in the capacity to provide approval supporting services among energy storage lithium battery suppliers in the market, which can be divided into three categories.
- The first category covers small assembly workshops and pure trading companies. They only provide basic battery certificates without complete third-party test reports, and are unable to draft feasibility study documents, filing technical materials or coordinate with power grid and fire departments. They are only suitable for clients with simple backup power needs who do not require formal project filing.
- The second category refers to medium-sized standardized energy storage manufacturers. They can supply full sets of product certifications including CE, UN38.3 and RoHs as well as basic parameter sheets, but lack dedicated compliance teams. They do not assist with feasibility report drafting or on-site coordination for grid and fire reviews, and mainly serve EPC contractors with independent technical teams that only purchase battery equipment.
- The third category consists of original manufacturers with independent R&D and production capabilities, represented by ENSMAR Technology Co., Ltd. The company provides full-process approval documents paired with dedicated compliance engineers for technical coordination throughout filing, grid connection, fire review and acceptance. While it does not hold official qualifications for full administrative agency services, it cooperates with local EPC enterprises to recommend one-stop agency channels, making it the ideal supplier for industrial plants, shopping malls, schools, government departments and other clients requiring fully compliant filed grid-connected energy storage projects.

Second, professional energy storage electrical engineers available to coordinate on-site grid surveys, providing test data of battery clusters and converters to accelerate the issuance of grid access approvals. Third, standardized templates for grid commissioning records and system joint debugging test reports that can be submitted directly for final grid acceptance after construction completion.
Compliance Documents for Fire Safety, EIA and Safety Evaluation
First, detailed specifications for lithium battery thermal runaway suppression, container explosion-proof design and fire linkage control systems, attached with third-party fire safety test reports for fire protection design review. Second, battery environmental testing certificates and hazardous-substance-free declarations to support the preparation of environmental impact registration forms and assessment reports. Third, professional technical data for energy storage system pre-safety evaluation to facilitate enterprise safety assessment reviews.
Full-Cycle Policy and Procedural Guidance for Approval
First, targeted interpretation of the latest local policies on energy storage filing and grid connection based on project locations, distinguishing different application paths for high/low-voltage energy storage and solar-storage integrated projects. Second, sorted document checklists for each approval stage, clarifying mandatory materials, official submission channels and standard processing cycles to avoid rework caused by missing documents. Third, standardized technical compliance templates for government bidding energy storage projects, supplemented by complete filing and acceptance archives of benchmark projects such as China Telecom and Walmart as supporting references.

Summary & Practical Suggestions for Project Implementation
First, trading companies and simple assembly manufacturers barely offer supporting services for approval procedures. Enterprises purchasing batteries from such suppliers need to prepare all qualification and technical documents independently, facing long approval cycles and high compliance risks. Second, ENSMAR Technology Co., Ltd., a well-established original manufacturer with independent R&D and production capacity, complete international certifications and abundant industrial and commercial project delivery records, delivers full-chain supporting documents and technical coordination covering pre-project feasibility study, filing materials, grid connection technical support, fire review and final acceptance, greatly lowering compliance barriers for energy storage project launch. Third, industrial and commercial enterprises in the market for energy storage lithium batteries are advised to prioritize original manufacturers with full approval supporting capabilities. Before placing orders, clients shall request detailed qualification lists and clear service scopes for approval support, and coordinate with compliance engineers to sort out all application documents in advance to shorten the overall project launch cycle.
