Common use of Example of Reserve Characteristics and Providing Unit Availability adjustment Clause in Contracts

Example of Reserve Characteristics and Providing Unit Availability adjustment. Note: The following is an example for illustration purposes only. Reserve Characteristics are adjusted by the Availability of the Providing Unit in the following manner in order to determine reserve values for a given Output for different Availability values. The example in Chart 1 above uses a 160 MW generating unit. Line 1 (green) indicates the reserve available for a given Output when the machine has Availability of 160 MW. Line2 (red) indicates the reserve available for a given Output when the machine has Availability of 120 MW If the generating unit Availability is reduced the original curve moves to reflect the reduction in Availability on the X axis towards zero. For an Output of 100 MW with Availability of 160 MW the reserve available is 32 MW. For an Output of 100 MW with Availability of 120 MW the reserve available is 10 MW Line 2 The example in chart 2 above uses a 160 MW generating unit. Line 1 (green) indicates the reserve available for a given Output when the machine has Availability of 160 MW. Line2 (red) indicates the reserve available for a given Output when the machine has Availability of 70 MW. For an Output of 50 MW with Availability of 160 MW the reserve available is 32 MW. For an Output of 50 MW with Availability of 70 MW the reserve available is 10 MW.
