Commissioning Services for Data Centres, Energy & Industrial Projects
TES Group delivers advanced commissioning services across data centres, energy, oil & gas, and industrial sectors, ensuring systems are installed, tested, validated, and fully operational in line with project specifications and industry standards.
We provide structured, end-to-end commissioning support from early-stage installation through to final system handover, working closely with contractors, project teams, and client stakeholders to ensure a safe, efficient, and fully compliant transition to operation.
Our approach is built around methodical planning, technical expertise, and controlled execution, enabling us to deliver commissioning solutions on complex, high-value projects.
Our Commissioning Services Include :
– Pre-commissioning inspections and verification
– Mechanical completion checks
– Loop checking and instrumentation validation
– Functional testing of systems and equipment
– Electrical energisation and start-up
– Performance testing and system validation
– Integrated system testing (IST)
– Documentation, certification, and handover
Date Centre Commissioning (Level1-6)
TES Group delivers commissioning services for hyperscale and enterprise data centres, following a structured Level 1 to Level 6 commissioning framework to ensure system reliability, redundancy, and continuous uptime.
– Level 1 – Factory Witness Testing (FWT)
Verification of critical equipment at manufacturer facilities prior to delivery, ensuring compliance with technical specifications.
– Level 2 – Site Installation Verification
Inspection and validation of installed systems to confirm correct installation and alignment with design intent.
– Level 3 – Pre-Functional Testing
Static testing of individual components and systems prior to energisation, including mechanical and electrical verification.
– Level 4 – Functional Performance Testing
Dynamic testing of systems under controlled conditions to confirm correct operation and system functionality.
– Level 5 – Integrated Systems Testing (IST)
Full system integration testing, including redundancy validation, failover scenarios, and operational simulations across critical infrastructure systems.
-Level 6 – Operational & Performance Validation
Final validation of system performance under live operational conditions, ensuring reliability, resilience, and readiness for full service deployment.
This process ensures that data centre environments achieve maximum uptime, resilience, and operational integrity prior to handover.
Oil & Gas / Power Generation (Cold & Hot Commissioning & Plant Start-Up)
TES Group delivers comprehensive commissioning services for oil & gas facilities and power generation systems, ensuring safe and controlled plant start-up and full operational validation.
– Cold Commissioning (Pre-Operational Phase)
Cold commissioning prepares systems for operation by verifying installation, functionality, and readiness prior to live process conditions.
Activities include:
– Mechanical completion certification and system walkdowns
– Cleaning, flushing, hydrotesting, and pressure testing
– Electrical pre-energisation and insulation testing
– Instrument calibration, loop checking, and signal validation
– Functional testing of systems without process media
– Verification of control systems, interlocks, and logic
This phase ensures systems are safe, clean, and fully prepared for energisation.
– Hot Commissioning (Operational Start-Up Phase)
Hot commissioning introduces live process conditions and validates system performance under real operating environments.
Activities include:
– Controlled introduction of process fluids, hydrocarbons, or energy systems
– Sequential system energisation and start-up
– Dynamic testing under operational loads
– Process stabilisation and optimisation
– Verification of safety systems, alarms, and shutdown functions
– Emergency shutdown (ESD) and trip testing
This phase ensures facilities operate safely, efficiently, and in line with design performance criteria.
– Power Generation Commissioning Capability
TES Group supports commissioning across a range of generation systems, including:
– Gas and steam turbines
– Combined cycle power plants (CCPP)
– Balance of plant (BoP) systems
– High-voltage electrical distribution systems
– Renewable and hybrid energy integration
We ensure full validation of generation and distribution systems, delivering stable and efficient power output from initial start-up.
– Integrated System Testing & Multi-Discipline Coordination
TES Group delivers full plant-wide integration and system testing, ensuring all mechanical, electrical, and control systems function as a single, unified operational system.
This includes:
– Integrated Systems Testing (IST) across multiple disciplines
– Interface validation between systems and packages
– Distributed Control System (DCS) and SCADA integration
– Load testing, redundancy verification, and failover testing
– Full plant start-up coordination and execution
Our integrated approach ensures seamless system interaction and operational reliability.
– Digital Tracking, Documentation & Handover
TES Group implements structured tracking systems to ensure full control and visibility throughout commissioning.
This includes:
– Test pack tracking and completion systems
– Punch list management and close-out
– Real-time reporting and progress monitoring
– Full documentation and certification for handover
This ensures complete traceability and compliance for all commissioning activities.
