Abstract: A system and method for planning outages for a power generation installation comprising a gas turbine power plant. The system and method utilizes a computer to receive requests from users to create maintenance plans for the power plant by generating templates, applying the templates to a database containing gas turbine data for the power generation installation; and receiving data from users to create maintenance package plans. Users can select either modular or turnkey maintenance plans. Modular maintenance package options enable a user to specifically select and obtain price quote information for parts and technicians who perform the maintenance tasks, and to specify particular shift options for the technicians.
