Understanding who handles which aspect helps create an efficient permitting plan, reduces redundancies, and clarifies the documentation required at each stage.

3) Permitting pathway: from concept to construction

The permitting process for BESS typically unfolds in stages. While the exact sequence can vary with project size, location, and local regulations, the following framework provides a practical roadmap for 2024 and beyond:

1. Feasibility and site selection
2. Preliminary approvals and land-use planning checks
3. Electrical interconnection studies and connection agreement
4. Environmental considerations (EIA scoping or screening if applicable)
5. Building and occupancy permits, plus electrical installation permits
6. Grid code compliance testing and commissioning
7. Operational licensing and market participation commitments

Let’s break down each stage with key actions and typical documents.

Stage 1: Feasibility and site selection

During feasibility, evaluate:

• Project purpose (firm capacity, energy arbitrage, ancillary services, renewable integration)
• Battery technology and safety standards (thermal management, fire suppression, monitoring)
• Site characteristics (land ownership, environmental sensitivities, access to infrastructure, proximity to load centers)
• Expected performance metrics (round-trip efficiency, degradation profile, cycle life)
• Preliminary grid interaction considerations and potential reinforcements

Deliverables typically include a concept design, preliminary power and energy rating, high-level safety and environmental considerations, and a rough permitability assessment.

Stage 2: Land-use and building permissions

Building and land-use permissions are central. Depending on the site and project scale, you may need:

• Land-use approval or zoning clearance from local authorities
• Building permit (stavební povolení) for structural, electrical, and civil works
• Possibly a simplified permit if the project qualifies as an installation under small-scale thresholds
• Comprehensive documentation including site plans, construction drawings, and safety engineering reports

Coordination with landowners, lenders, and contractors is essential to align timelines and avoid delays.

Stage 3: Electrical interconnection and grid studies

Grid connection is a critical bottleneck in some markets. In 2024, Czech procedures emphasize:

• Interconnection studies performed by the DSO/TSO to determine required network reinforcements, fault ride-through capabilities, and protection coordination
• Preparation and submission of connection request letters, with accompanying technical data sheets, single-line diagrams, and protection philosophy
• Negotiation of a connection agreement outlining capacity allocation, estimated connection charges, and scheduling for construction of interconnection works

Keep in mind that larger projects may undergo more rigorous studies, especially if they impact network stability or require significant upgrades.

Stage 4: Environmental approvals

Environmental considerations range from minimal to substantial. You should assess:

• Whether an Environmental Impact Assessment (EIA) is triggered by project size or location
• Baseline environmental studies and potential mitigation plans for noise, fire risk, and land use
• Public consultations and stakeholder engagement requirements
• Compliance with national and EU environmental standards for storage facilities

Even if an EIA is not mandatory, applicants may still pursue an environmental report to support permit decisions and financing packages.

Stage 5: Construction permits and electrical installations

With land-use and environmental approvals in place, you proceed to:

• Procurement and verification of electrical equipment compliant with EU and Czech standards (IEC/EN standards, CE marking)
• Issuance of construction permits for electrical installations and structural components
• Inspection arrangements with authorities and safety testing prior to commissioning

Documentation at this stage typically includes full construction drawings, safety plans, fire protection strategies, and commissioning procedures.

Stage 6: Commissioning, testing, and operation

Before going online, verify:

• Protection and control systems tested and validated against design specifications
• Metering, telemetry, and communications for grid reporting and market participation
• Emergency procedures, staff training, and maintenance plans
