Evaluate Power Plant Performance Guarantees in New and Upgraded Plants
TGPS conducts and supervise the contractual power plant performance test used to validate the power plant performance guarantees in large power generation projects around the world.
The contractual power performance test is of great importance in this infrastructure projects to ensure the power plant performance commitments are met.
The contractual performance test is full of technical and contractual details. Therefore, the experience of the team conducting or supervising these test is a must. The compliance with the international performance testing protocols is important, testing codes from international organizations should be followed (ASME, IEC, DIN, ISO, etc)
Typical parameters that are typical in the power plant performance guarantees are Power Output, Heat Rate, Boiler efficiency, Gas Turbine Efficiency, Steam Turbine Efficiency, auxiliary consumption among others.
The contractual power plant performance test applies as well to periodic testing on LTSA contracts or O&M contracts with performance guarantees.
Determine if the power plant performance meets the power plant performance guarantees.
TGPS acts as the contractual performance test director or supervision.
Determine how to Improve the Overall Power Plant Performance
TGPS can conduct a diagnostic of the current overall power plant performance to determine areas for improvement. This evaluation allows our customers to visualize in which equipment an investment will impact the performance of the plant in a greater way.
The diagnostic focus on evaluating the overall power plant performance. For this, TGPS evaluates the thermal performance of the major plant equipment. We use EBSILON as the modeling software to identify with precision the efficiency shortfalls around the plant and evaluate the impact of those into the overall power plant performance.
We either can diagnostic the current power plant performance or conduct an evaluation to determine the impact of certain event in the plant (i.e. maintenance, upgrade, changes in fuel, etc)
Determine the current state of the plant in terms of efficiency.
Establish a baseline performance and identify the areas where an investment will provide the highest return. Also, we can evaluate the impact of a maintenance, upgrade or plant modification
TGPS conducts the diagnostic of the plants using specialize modeling software.
In some instances we have been asked to supervise and review the performance evaluation conducted by other companies.
Determine the Plant Performance Parameters Used for the Economic Dispatch
Several countries have been moving to use an economic dispatch model in which the goal is to increase the efficiency of the electricity produced at the minimum cost. For this, several dispatch centers around the world are conducting a power plant performance audit to be able to plant the generation of the country based on solid data.
TGPS has been working with the energy ministers of different countries to conduct power plant performance audits that generate the parameters required by the dispatch centers.
Typical Parameters to Evaluate are Heat Consumption curves Vs Load, power plant capacity minimum load, startup and shut-down costs.
Conduct power plant performance evaluations of the power generation fleet of countries to determine the parameters used for the economic dispatch. A lot of the work is very well documented as these become documents that determine the revenue model of plants.
TGPS works directly with the dispatch centers or energy ministers of different countries.
TGPS conducts high accuracy independent power plant performance testing services for different purposes. Acceptance, Diagnostic of performance evaluation audits. The activities we conduct are:
Creation or Revision of the Power Plant Performance Test Procedures. Compliance with the ASME, ISO, DIN, IEC Testing Codes. (i.e. ASME PTC 46, ASME PTC 6, ASME PTC 4, ASME PTC 22, etc)
Modeling of Power Plants to ensure accurate results and diagnostic of individual equipment performance. Using a thermal performance model of the plant, TGPS can do a detailed assessment of the opportunity areas of the plant to increase the performance of the plant.
Conduct a detailed calculation of the power plant performance test results. The results are customized based on the main objectives of our clients.
Provide high-accuracy power plant performance testing instrumentation to meet the uncertainty levels required by the contractual or testing requirements.
