Turnkey maintenance of a customer's aircraft fleet is managed by a single management service provider (MSP) controlling integrated maintenance and materials services from a central operations site. The MSP converts data received directly from on-board aircraft systems into information it uses to manage maintenance service providers and parts suppliers. The MSP contracts with and manages maintenance, repair and overhaul organizations (MROs) who perform the maintenance on the customers' aircraft at line and base stations. The MSP either remotely manages part inventories at the customer's site, or manages suppliers who deliver the parts to the MROs. Maintenance planning, scheduling and execution information is exchanged between the MSP, MROs, part suppliers and the customers through a shared data communication network controlled by the MSP. The MSP charges the customer for the maintenance services based on a flat rate per unit of aircraft flying time.

A method to provide Primary Frequency Regulation to a steam turbine in a combined cycle plant that comprises storing energy in the form of internal energy of the steam contained within the piping and domes of the heat recovery boilers, and then using said energy when the power grid requires a sudden increase in output power. With the present method, the losses in power generation of the steam turbine, when said turbine is operating in the Primary Frequency Regulation mode, are reduced to a minimum. When the gas turbines in a combined cycle plant operate in PFR mode, the steam turbine reduces its output power because the gas turbines must operate below their rated power. The present method converts said decrease in output power of the steam turbine in a Spinning Reserve useful for PFR in said turbine. That is to say that the present method converts said Spinning Reserve in a rapid reserve, available after just a few seconds; if necessary, response times of less than 10 seconds can be attained. The present method introduces several novel steps, which constitute its essence, said steps permitting the continuous, long term operation of the steam turbine in a combined cycle plant in PFR mode, thereby ensuring at any time the effectiveness of mains frequency regulation and also guaranteeing the stability of the power generation process in said combined cycle plant.

A technique is provided for operating a wind farm at increased rated power output. The technique includes sensing a plurality of operating parameters of the wind turbine generator, assessing the plurality of operating parameters with respect to respective design ratings for the operating parameters, and intermittently increasing a rated power output of the wind turbine generator based upon the assessment.
