Commissioning & Performance Testing

Reach COD with disciplined test readiness not last-minute firefighting. Protocols, evidence trails, and performance validation that reduce disputes and carry cleanly into warranty and operations.

Commissioning is where delivery either becomes an operating asset or a dispute

Most schedule slips and post-COD surprises come from weak commissioning controls: incomplete pre-reqs, unclear test ownership, inconsistent SCADA signals, and punch lists that don’t close. MetRenew structures commissioning as a governed pathway pre-commissioning readiness, test protocols, interface validation, and evidence capture aligned to contractual acceptance criteria. The outcome is faster COD, fewer re-tests, cleaner documentation, and a smoother handover into operations, warranties, and claims management.

Our Solutions

Commissioning Strategy & Test Governance (COD-back planning)

We work backward from contractual acceptance to define test sequence, prerequisites, responsibilities, and sign-off gates. This prevents “test-day surprises,” protects the critical path, and aligns EPC, OEMs, grid interface, and O&M readiness around a single commissioning plan.

Pre-Commissioning Readiness & Interface Closure

We establish readiness gates for mechanical completion, QA/QC dossiers, as-built verification, spares and tooling, and interface sign-offs (substation, protection, PPC, SCADA). The goal is fewer stoppages during energization and fewer rework loops during functional testing.

Functional Testing, SCADA Validation & Controls Verification

We validate signals end-to-end (field → SCADA/historian → alarms → reporting) and verify control behavior (setpoints, ramping, curtailment response, reactive capability). This reduces false alarms, missing telemetry, and control instability that can block grid synchronization and acceptance.

Performance Testing & Guarantee Validation

We structure protocols for PR / energy yield validation (as applicable), capacity and availability evidence, and BESS performance checks where relevant. Evidence trails are designed to align with contract terms so results are defensible and disputes are minimized.

Punch List Discipline, Documentation Handover & Warranty Readiness

We run closure governance: punch list prioritization, defect categorization, retest triggers, and final handover packs. This creates an operations-ready baseline critical for warranty enforcement, SLA tracking, and claims evidence from day one.

Use Cases & Outcomes

COD at risk due to incomplete readiness gates

Multiple contractors arrive at energization with open prerequisites. Outcome: a single readiness dashboard, gated sign-offs, and a test sequence that protects the critical path and reduces re-tests.

SCADA/controls issues blocking acceptance

Telemetry gaps and unstable plant behavior trigger repeated failures. Outcome: end-to-end signal validation and controls verification so synchronization, curtailment response, and alarms meet acceptance criteria.

Hybrid site commissioning (Solar + BESS) with tight interfaces

Systems interact but responsibilities are unclear. Outcome: interface closure and coordinated functional testing across inverter/BESS/PPC/EMS to prevent integration failures and acceptance delays.

Performance test dispute risk with lenders/offtakers watching

Results are questioned due to weak evidence. Outcome: contractual alignment of protocols and defensible evidence packs that reduce disputes and support clean handover into warranty periods.

Why Metrenew

Commissioning-first delivery discipline

We design commissioning as a governed pathway with prerequisites, ownership, and decision gates so testing is predictable, not improvised.

Evidence that survives scrutiny

Test results are only valuable when defensible. We prioritize traceable documentation, repeatable protocols, and clean sign-offs aligned to acceptance clauses.

Handover that protects operations and claims

Commissioning outputs are structured to support warranty enforcement, SLA tracking, and claims readiness so issues become recoveries and fixes, not revenue leakage.

Turn COD into a controlled pathway without re-tests and disputes

Frequently Asked Questions

What does commissioning & performance testing include?

A governed pathway from readiness to acceptance: prerequisites, test sequencing, functional validation, controls/SCADA verification, performance validation, punch-list closure, and documentation packs aligned to COD and contractual acceptance.

How do you reduce re-tests and commissioning delays?

By enforcing readiness gates, closing interfaces early, aligning responsibilities, and using repeatable protocols so issues are found before energization, not during it.

Do you support both solar and BESS commissioning?

Yes. We structure test governance across solar, BESS, and hybrid configurations, with focused attention on controls, telemetry, safety requirements, and interface responsibility.

What are the most common commissioning failure points?

Open prerequisites, interface gaps, SCADA signal inconsistencies, unclear test ownership, and punch lists that don’t close leading to repeated stoppages and delays.

Do you define testing protocols and acceptance criteria alignment?

Yes. We align protocols and evidence capture to acceptance clauses so results are defensible and disputes are reduced.

How does SCADA validation fit into commissioning?

It ensures field signals, alarms, reporting, and controls behave correctly end-to-end critical for acceptance, stable operation, and reliable performance tracking.

What does “clean handover” mean in practice?

Closed punch lists, complete documentation, validated baseline performance evidence, and warranty-ready data so operations can run and recoveries can be enforced from day one.

When should commissioning planning start?

Early during engineering and procurement so interfaces, telemetry, and test readiness are designed in, not “patched” during site execution.
