The document summarizes the start-up and commissioning process for a 1200 megawatt gas turbine power plant. Managers first prepare detailed plans and review specifications. Then during commissioning, specialists conduct performance tests to ensure equipment is functioning properly and the plant systems are ready. They prepare documentation and train operators and maintenance crews. The start-up manager establishes schedules and safety standards. On-site engineers conduct component testing, flushing, cleaning, and initial equipment operation tests. Key start-up events include electrical back-feed, first fires of combustion turbines, and performance testing of steam turbines. Finally, start-up experts train plant personnel to operate and maintain the new facility.

START-UP & COMMISSIO
1,200 MEGAWATT GAS TURBINE POWER PLANT
The power plant is a two-unit 1200 MW steam turbine generator plant with the usual
additional features of:
Water treatment building Warehouse/machine shop
Administration building Guardhouse
Fuel-oil pump house Intake building
At the start of the project, managers prepare a detailed plan and schedule. They review
drawings, specifications and plans. During the critical final phase of commissioning, specialists
in the field conduct performance tests to assure that equipment is functioning as specified and
that the plant systems are ready for operation. They prepare plant documentation and train the
plant operators and maintenance crew. The start-up and commissioning must be detailed and
flexible to cater for all events. The teams must be ready to respond to any surprises but keep
within the planned schedule of time and costs.
Start-up services include preparation of operation and maintenance manuals, system
descriptions and operating instructions, and integrated operating instructions, including
vendor O&M manuals.
The start-up manager must perform the following duties.
• Establishes a contractor release schedule and packages.
• Schedules test witnesses and monitoring
• Sets safety and environmental standards
On-site field engineers conduct:
• Component testing
• Flushing
• Chemical cleaning
• Steam blowing
• Initial equipment operation system facility tests such as performance, emissions,
and noise control.
Key start-up events included:
• Electrical back-feed
• First fire of each combustion turbine generator
• Testing of the steam supply to the steam turbine generators
• Performance testing
When the facility is operational, start-up and commissioning experts train power plant
personnel to operate and maintain the new plant or system. They provide direct instruction
about the balance of plant systems and coordinated vendor training for control systems,
turbine generators, and the water treatment.
