ILB Turnkey Services Solar & BESS Projects

Pre-evaluation

We create a preliminary project that meets our customer’s needs, in order to calculate your individually planned BESS & solar projects.

Development

We continuously develop our products, ensuring that your solar projects & BESS Systems meet the highest economical benefits and technical requirements.

Bankability / IRR

Beyond certifying the safety and performance of your photovoltaic & BESS product, we provide you with the tools to make your PV & BESS project “bankable”.

Origination & Development

We are continuously screening possible PV & BESS project opportunities worth to be taken over as lead developer. We engineer and build to fully meet international investor expectations. Any Origination & Development process is based on four major topic clusters.

Planning & Optimization

Every PV & BESS plant needs to be aligned with the local specifications of the land to be built on such as topographic and geological situation, sun irradiation and angle, wind and snow load, general electrical requirements of the grid and so on.

Construction & Project Management

Strict scheduling, professional project management, cost management, permanent quality assurance and problem management must be seen as the key for a successful and on-time construction and grid connection of a PV or BESS Plant.

Operation & Maintenance

The typical O&M issues usually include aspects related to product availability, engineering errors, grid problems, extreme weather events, O&M staff or incorrect maintenance work.

Investor Solutions & Financial Management

PV & BESS investment represents one of the fastest growing areas of energy investing and has the advantage of being relatively new compared to other industries. PV & BESS technology makes up the most widely used and popular renewable energy technologies today.

ILB Turnkey BESS EPC – Services

EPC Scope for BESS & ESS Projects

As a turnkey EPC contractor (Engineering, Procurement and Construction), we take full responsibility for the turnkey delivery of the plant.

The scope of work is divided into three main phases:

Engineering (Planning & Technical Design)

System design: Dimensioning of battery capacity and discharge power (e.g. 100 MW / 400 MWh) according to the application, such as peak shaving or grid stabilization.
Electrical integration: Design of inverters converting direct current (DC) into grid-compliant alternating current (AC).
Safety concepts: Integration of fire protection systems, temperature monitoring, and surge protection within the battery containers.
Grid connection design: Engineering of the grid interconnection (e.g. 33 kV or 345 kV), including switchgear and transformers.

Procurement (Sourcing & Logistics)

Component selection: Qualification of suppliers for battery modules (typically lithium-ion), battery management systems (BMS), and enclosures.
Logistics: Transportation, customs clearance, unloading, and safe storage of battery containers—often weighing several tons—at the project site.

Construction (Installation & Commissioning)

Civil works: Foundation works, placement of containers, installation of safety fencing, and landscaping.
Installation & assembly: Electrical cabling of all components and physical erection of the plant.
Commissioning: Execution of performance tests and acceptance procedures (Site Acceptance Testing) to verify guaranteed performance parameters.
Guarantees: Assumption of liability for schedule adherence and system performance (performance guarantees).

Engineering Phases & Key Deliverables for a BESS & ESS turkey project

Engineering Phases and Conceptual design & feasibility: Site assessment, technology selection, and determination of nominal power (MW) and energy capacity (MWh) based on applications such as peak shaving or grid stabilization. Front-End Engineering Design (FEED): Preparation of the design basis report, preliminary layouts, and estimation of system losses.

Technical Disciplines (Key Deliverables)
Regulatory Compliance & Acceptance

Technical Disciplines (Key Deliverables)

A complete engineering package includes detailed documentation for the following systems:

Electrical Engineering
- Single Line Diagrams (SLD): Representation of the DC system (battery racks, BMS) and AC connection (inverters/PCS, transformers).
- Protection coordination & short-circuit studies: Analyses to ensure system safety.
- Grounding concept & cable lists: Planning of DC and AC cabling.
Control & Automation
- Energy Management System (EMS): Control logic for charging and discharging strategies and interfaces to the grid operator.
- SCADA integration: Real-time monitoring and data acquisition.
Civil Engineering & Safety
- Layout drawings: Placement of containers, foundation plans, and access routes for emergency services.
- Fire protection & HVAC concept: Specification of climate control (HVAC) and fire suppression systems to prevent thermal runaway.

Regulatory Compliance & Acceptance

Grid connection studies: Demonstration of compliance with local grid codes and standards.
Testing & commissioning plans: Protocols for Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT).
Documentation: Operation & maintenance manuals (O&M), spare parts lists, and as-built drawings after project completion.

O&M and Spare Parts Concept for BESS & ESS Systems

A comprehensive Operation & Maintenance (O&M) concept for a Battery Energy Storage System (BESS) aims to ensure maximum availability, safety, and lifetime of the plant.

It essentially covers the following core areas.

Maintenance Strategies

Preventive maintenance: Scheduled inspections to avoid failures.
Battery system: Checks for cell balancing, physical damage (swelling, leaks), and cleaning of terminals.
HVAC systems: Cleaning or replacement of filters and functional testing of cooling circuits to maintain optimal temperatures
Electrical systems: Tightening of cable connections (to avoid contact resistance) and inspection of inverters (PCS) and transformers.
Corrective maintenance: Processes for rapid troubleshooting and repair after unplanned events.
Predictive maintenance: Use of data analytics to detect failures in advance (e.g. monitoring degradation rates).

Monitoring & Data Management

KPI monitoring: Continuous tracking of state of charge (SoC), state of health (SoH), cell temperatures, and round-trip efficiency (RTE).
Remote monitoring: Remote access via SCADA or EMS systems for real-time diagnostics and alarm handling.
Reporting: Regular reports on system performance and compliance with warranty conditions (e.g. number of cycles, depth of discharge).

Safety & Emergency Management

Fire protection: Regular inspection of fire detection and suppression systems and gas detection for early identification of thermal runaway.
Emergency procedures: Definition of shutdown protocols and coordination with local fire departments.
Physical security: Inspection of fencing, CCTV surveillance, and access control systems.

Asset Management & Warranties

Warranty management: Ensuring all maintenance activities are carried out in accordance with manufacturer requirements to preserve warranty claims (often 10–20 years).
Spare parts management: Availability of critical components (e.g. fuses, fans, individual battery modules) on site or via service partners.
Insurance concept: Product and Performance insurance

A well-structured O&M concept is essential for bankability and the return on investment (ROI) of the project.
