Utility-Scale Plant & Distributed Generation Facility AQCS Testing & Evaluation Services 

Plant & Facility (Contractual Acceptance or Routine)

McHale’s Performance Services provides performance testing for the contract procurement of Air Quality Control (AQC) Systems (AQCS) and components. Specifically, our performance testing is designed to verify contractual guarantees at the level of confidence expected by the parties of the contractual acceptance test and to ensure the successful closure of the project. Through strategic and proven subcontracting relationships with emissions testing companies, McHale provides a comprehensive testing program based on clear expertise with EPA, ASME, ANSI, ISO, ASTM, and EPRI code techniques.

McHale also provides benchmark status and performance optimization testing to our clients to ensure that AQC systems have not degraded to unacceptable levels and to identify where program improvements can be made to improve the effectiveness, efficiency, consumption, and economic performance.  McHale can provide the required performance testing and evaluation services in order to verify the performance AQCS to establish confident benchmarks for planning optimized coordinated plant operation and outage maintenance projects.

Technical Advisor

McHale has technical advisors that are experienced in serving as “owner’s engineers” that identify, quantify, and mitigate risks associated with AQCS performance for our clients.  We have assisted project owners, financial institutions, and legal counsel with advising/consulting services and performance audits.   McHale Advisors understand the importance of reviewing proposed designs, developing strong contractual language, construction monitoring, and witnessing key tests to ensure performance guarantees are achieved with confidence to ensure the success of a project.

 Test Code Specialists

McHale is recognized throughout the power generation market as a specialized engineering group that provides superior testing and plant performance improvement services. McHale is actively involved and versed in the ASME Test codes and has extensive experience conducting tests utilizing international test codes and standards:

  • 40CFR 60 and 75
  • ASTM Collection & Sampling Methods
  • EPA methods cited in the Code of Federal Register, CFR 40 part 60, Appendix A
  • ASME Test Codes

We are experienced in how to properly apply these codes and other international standards to successfully demonstrate contractual acceptance with the level of confidence for lenders, owners, OEM’s and EPC’s demand.

Qualified & Impartial Test Personnel

McHale has worked with a variety of EPC contractors, plant owners, and manufacturers throughout the power industry.  The McHale team is known for quick response time, expertise in AQC systems and component issues, and accurate results.
