Construction authorization for an energy storage project depends on the defined facility, its consequence class and the applicable procedure. Under the general procedure, CC1 projects use a notice of commencement of construction works; CC2 and CC3 projects require a permit. Completion of installation does not itself mean the facility has been accepted into operation. The client must coordinate design, inspections, supervision and final documentation, while addressing grid connection conditions separately.
Define the facility and responsibility for design decisions
First define the facility's scope: storage equipment, foundations, transformer, cable infrastructure, controls and works at an existing business. New construction and reconstruction start from different circumstances. Do not call the entire project "battery installation" if structures are being built or an existing facility is being altered.
Design documentation combines explanations, drawings, calculations and other required materials. It must reflect the design inputs and safety requirements. A manufacturer's catalog, a commercial proposal diagram or an equipment list does not replace the construction design.
Identify an appropriately qualified lead engineer or project architect and those responsible for related disciplines. The contract should specify deliverables, client-provided inputs, how comments will be addressed and how results will be handed over. This reduces the risk that the electrical design is complete while foundations or external networks fall outside the agreed scope.
Before design starts, check land and planning conditions, technical conditions, the design brief and required investigation results. The designer needs the actual rights boundaries, grid conditions and site constraints rather than assumptions from a photograph.
Agree design stages and construction phases in the brief. Do not automatically select a working design merely because equipment is containerized. For phased commissioning, the design should describe each phase and whether it can operate safely on its own. Coordinate document procedures with that division.
Determine the consequence class for the specific facility
The consequence class reflects potential danger to people and material and social losses if a facility fails. The design organization determines it while preparing documentation. Battery capacity or the number of cabinets alone is not sufficient.
The assessment considers people on and off site, consequences of interruption and impacts on infrastructure. Also check the established restrictions on assigning CC1. A claim that all energy storage installations are CC1 is not an acceptable basis for selecting a procedure.
For reconstruction, justify whether the assessment covers the entire reconstructed facility or a properly separated part. Its boundaries must match the design. Splitting supply across several contracts does not prove that construction facilities are independent.
Ask the designer for the calculation and assumptions, not just a class on the cover sheet. Where expert examination is mandatory, the class determination is checked as part of it. A change in project scope requires reassessing whether the initial conclusion still holds.
Environmental impact assessment and design examination are different
Environmental impact assessment (EIA) concerns the planned activity and its effects. Determine whether it applies before finalizing design decisions. Assess the whole project, including storage, associated networks, generation facilities and changes to business operations.
Do not decide whether EIA is required based only on the term "energy storage". For a combined project, check the activities and conditions specified by law. If the procedure applies, its results are incorporated into the design. An explanatory environmental section does not automatically replace a separate EIA procedure.
Design examination assesses design decisions within a defined scope. Under the general procedure, CC2 and CC3 projects require examination. For CC1, check separate grounds, including complex engineering-geological or technogenic conditions and the funding source. The EIA applicability assessment may require revisiting the initial consequence class conclusion.
The scope depends on the legal basis: for example, checks of strength and reliability are not the same as review of cost estimates. The contract with the expert organization should state what is assessed. A positive report of any kind does not prove that every required examination was completed.
The designer addresses comments. When examination is mandatory, a positive result is needed for design approval. The client approves the current documentation, and the team verifies its details against the construction register.
For each procedure, record the basis, responsible person, required documents and expected result. If the team considers examination or EIA unnecessary, ask for a justification based on the actual project scope. Small storage capacity alone does not replace this check.
What is required before construction starts
The table shows the general procedure for construction facilities. It does not replace checks for special regimes and exceptions applicable to the actual works.
| Consequence class | Before construction works | Acceptance into operation |
|---|---|---|
| CC1, minor consequences | Submit the appropriate notice of commencement of construction works. | Register the declaration of facility readiness. |
| CC2 or CC3, moderate or significant consequences | Obtain a construction works permit. | Obtain a certificate based on the readiness report and required checks. |
A notice of preparatory works does not grant the right to perform construction works. Do not conceal equipment foundation work under "site preparation". Before the contractor starts, compare planned activities with the document authorizing them.
Check the facility's identity, approved design, expert materials where applicable, contractors and supervisors. Errors in links between records in the Unified State Electronic System in Construction can prevent processing. Submitting a permit application does not mean the permit has been issued.
Check special rules during martial law separately. Applicability depends on the current rules, facility parameters and procedural conditions. A temporary procedure is not a general exemption from design, safety or subsequent documentation.
Maintain supervision and records during construction
Designer's supervision monitors whether work follows the design. Technical supervision, arranged by the client using appropriately qualified specialists, checks compliance with design decisions and the quality and quantity of work. Neither function should be reduced to a final signature after installation.
As-built records document what was actually done, including concealed work, drawings, checks of materials, structures and equipment, and engineering-system tests. Prepare them during the works. For example, document a concealed cable route while the work can still be inspected.
Equipment substitution or changes to layout or routes require designer assessment. The designer determines whether documentation and associated checks must be revised. Avoid having one version on site, another in the design and a third in the application.
If the contractor, supervisors or other material information changes, check how register data must be updated. The team's working register should record the design revision, date, responsible person and affected documents.
Start with a list of each task, supporting document, responsible person and review status. Keep open comments visible to the client. Before handing over to the next contractor, confirm they have the latest drawings and know about agreed changes.
Acceptance, testing and grid access
To document completion, compare the actual facility with the approved design and assemble required materials. Depending on the procedure, the package may include as-built records, technical inventory data, a control survey and readiness information. Documents must describe the same scope and parameters.
Under the general procedure, confirm registration of the declaration for CC1 and obtain a certificate for CC2 and CC3. A readiness report, an application and an issued certificate are different documents. Address returned materials or refusals rather than treating the procedure as complete.
Reconcile the name, address, identifier and parameters across the materials. If a separate phase is being accepted, confirm the documents and works relate to that phase. Do not record the equipment delivery date or internal contractor acceptance date as the date of formal state acceptance.
Testing and acceptance of the storage system is a separate workstream. Functional checks, test records and a supplier's report confirm results only within their scope. They do not replace required construction acceptance or compliance with grid operator conditions.
In parallel, verify metering, protection, the agreed scheme and required documentation for grid operation. For the selected business model, separately establish whether an energy storage license is needed. Construction paperwork alone does not decide that question.
Client checkpoints
- 01. Prepare the designFacility boundaries, inputs, class, checks and approved design.
- 02. Perform the worksProper legal basis, supervision, change control and as-built records.
- 03. Confirm readinessAcceptance, applicable formal commissioning and separate grid operating conditions.
- Assign responsibility for each document and approval.
- Reconcile the consequence class with the designer's justification.
- Resolve the applicability of EIA, examination and special rules.
- Check that actual works match the current design revision.
- Record the acceptance result and outstanding operating conditions separately.
Hypothetical example. A business has installed storage and received an installation report. However, the cable route differs from the design and construction completion formalities remain unfinished. The team first assesses the deviation, updates the documentation properly and completes the required checks. The installation report does not resolve those issues. This is an illustrative scenario, not an ONG project.
If the project includes solar generation, discuss solar power plant design. Storage documentation, legal support and allocation of responsibility are agreed separately. Include the expected deliverables for each stage in the contract.
