Monitoring & Testing

In today’s power industry, plant personnel have fewer resources and time available to quantify one of the most critical aspects of a power plant: thermal performance. GSE Engineering, Programs & Performance group (formerly True North Consulting) is highly qualified to perform routine thermal performance and equipment acceptance testing. Our engineers have extensive experience in various types of power plant testing in accordance with the applicable industry standard test codes (ASME, ATC, ASHRA, etc.)

Thermal Performance Monitoring

GSE’s Thermal System Monitoring (TSM) software will provide analysis and reporting of the thermal performance of power plants, helping reduce manpower, errors, and costs in operations.

Thermal Performance Testing

Results from thermal performance tests assist plants in quantifying equipment performance, identifying and quantifying losses, minimizing or preventing future losses, and optimizing unit operation. Additionally, testing can be used to meet environmental or grid controller requirements.
