Heat rate, output and capacity verified to ASME PTC — the test report that signs off acceptance, releases retention and stands up to lender review.
Plant performance testing is the moment when contractual numbers — heat rate, net output, condenser performance, fuel consumption — get converted into a measured value that everyone in the contract chain has to accept. Acceptance certificates, retention releases and bankability assessments all wait on this report.
Our clients fall into five archetypes. Each one sits on a different side of the same number, but every one of them needs the same thing in the end: a corrected, defensible measurement under an independent third-party signature.
Project owners verifying that the EPC contractor delivered the heat rate and output written into the contract before retention is released.
Fleet operators tracking degradation, validating dispatchable capacity and supporting commercial agreements with measured performance data.
Acceptance test campaigns to prove the plant meets the technical guarantees they signed — independent measurement preserves the handover.
Equipment suppliers validating new-and-clean performance at startup, baseline-establishing for warranty periods, and re-rate testing after upgrades.
Independent verification of performance guarantees for non-recourse project finance — including post-COD bankability re-tests.
Every Plant Performance engagement produces the same set of artifacts. You know exactly what arrives at the end of the campaign — and what the EPC contractor, owner and lender each receive for sign-off.
Documentation is authored in the language the parties read. We deliver in English, Spanish, Portuguese or Arabic — adapted to the contractual format the project was negotiated in.
Tailored to the applicable ASME PTC code (22, 46, 53, 6, 19), plant configuration and contractual boundary. Reviewed with owner and EPC before mobilization.
Fuel flow, fuel quality, ambient conditions, output power, thermal flows — all timestamped, all traceable to international calibration standards.
Raw measurements corrected to reference conditions (ISO ambient, design fuel, contractual boundary) per the applicable PTC correction curves.
Full ASME PTC 19 uncertainty propagation. Required for any defensible heat rate, output or capacity claim that holds up in arbitration.
Consolidated final report — methodology, measurements, corrections, uncertainty, comparison to guarantee. The document that releases acceptance.
We attend the acceptance review, respond to EPC or owner queries and supply clarifications until the certificate is signed.
Every engagement follows the same disciplined methodology, written against the applicable ASME PTC code. Each phase produces specific deliverables that gate the next phase. Every measurement, correction and assumption is documented and traceable.
This is the methodology that survives EPC/owner negotiation — and that gives lenders the confidence to release retention at acceptance.
Guarantee parameters. PTC code selection. Test boundary definition. Correction curves audit.
Instrumentation plan, calibration coordination, run matrix, EPC/owner coordination.
On-site campaign. Pre-test, runs, post-test. Real-time data validation, safety protocols.
Raw-to-corrected data reduction, PTC-19 uncertainty propagation, guarantee comparison.
Report delivery, owner/EPC review meeting, query response, acceptance certificate.
Performance testing lives or dies on the calibration cycle. Every flow meter, RTD, pressure transmitter and power analyzer we deploy is on a documented calibration record, traceable to international standards. We mobilize what the test program requires — and we re-verify calibration on site when the measurement matters most.
Analysis runs in our internal performance suite with native ASME PTC-19 uncertainty propagation, plus heat balance models for combined-cycle and HRSG configurations.
ISO/IEC 17020 accreditation as a Type A inspection body is in progress, expected to complete in 2026. The methodology and instrumentation already meet the technical requirements — accreditation formalizes what is already in place.
Our performance work is tested against ASME PTC codes — the international consensus for plant performance — and supplemented with ISO and IEC standards where the contract calls for them.
International accreditation for inspection bodies. The credential international lenders and DFIs recognize for independent third-party verification.
Every campaign is written, executed and reported against the applicable ASME Performance Test Code — the international benchmark for power plant acceptance testing.
Performance test campaign at NAES El Norte III combined-cycle facility in Mexico. Full ASME PTC 46 plant-level acceptance program, executed alongside the operator's commissioning team. Owner-side independence preserved while integrating with the EPC's acceptance schedule.
Acceptance test report delivered without query — guarantee comparison, full PTC-19 uncertainty propagation, and contractual sign-off package authored end-to-end in-house.
The acceptance certificate was signed on first review — the result of a methodology that builds defensibility into every measurement, every correction, every uncertainty estimate. No re-tests. No disputed numbers.
