McHale’s Renewables provide benchmark status performance testing to our clients to ensure that plant performance has not degraded to unacceptable levels and to identify where program improvements can be made to improve the efficiency, output, and economic performance.  Whether it is Optimization of single hydro plants and of multiple plants that operate in a coordinated manner, McHale can provide the required performance testing in order to verify the performance of individual units and multiple facilities to establish confident benchmarks for planning optimized coordinated plant operation.

McHale Renewables also provides performance testing for the contract procurement of new turbines or runners and new pumps or impellers, or in the rehabilitation of such equipment.  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 successful closure of the project.

Technical Advisor

McHale Renewables has technical advisors that are experienced in serving as “owner’s engineers” that identify, quantify, and mitigate risks associated with plant 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, development of strong contractual language, construction monitoring, and witnessing of key tests to ensure performance guarantees are achieved with confidence so to ensure the success of a project.
