Ramp Rates. (i) Seller shall ensure that the ramp rate of the Facility is less than the following limits for all conditions including start up, normal operations, Seller adjusting the Facility Actual Output, changes in the solar resource, and shut down for the following periods as calculated in accordance with Attachment C (Methods and Formulas For Measuring Performance Standards). Maximum Ramp Rate Upward of [__] MW/minute for all periods. [TO BE DETERMINED FOLLOWING IRS.] Maximum Ramp Rate Downward of 2 MW/minute for all periods other than periods for which such maximum is not operationally possible because of rapid loss of solar resource and the depletion of energy storage.
Ramp Rates. [Describe ramp rates for each unit operating independently and for all units operating simultaneously. If unit ramp rates vary based on unit loading level, please provide a ramp rate for each segment within the operational range in which it differs.] Maximum operational ramp rate: ___ MW/minute. Maximum ramp rate when the Project has been shut down for 480 minutes: ___ MW/minute Maximum ramp rate when the Project has been shut down for 240 minutes: ___ MW/minute Maximum ramp rate when the Project has been shut down for 0 minutes: ___ MW/minute
Ramp Rates. (i) The Facility in start up, normal operations including when executing a command from the Company active power controls, and shut down shall adjust its net real power import or export at a ramp rate, as calculated in in accordance with Attachment C (Methods and Formulas for Measuring Performance Standards), to be specified by the Company without intentional delay. Such ramp rate shall be in the range of ____ MW/min to ____ MW/min.
Ramp Rates. [TO BE DETERMINED BY THE COMPANY UPON COMPLETION OF THE IRS] Seller shall ensure that the ramp rate of the Facility are less than the following limits for all conditions including start up, normal operations, and shut down (including high wind speed shut down in the case of Wind Facilities) for the following periods. Note that time periods are subject to seasonal variations and typical times of day/night are provided for general planning purposes only. Maximum Ramp Rate Upward of [TBD] MW/minute for all periods except during Early Morning Low-Load Periods (typically Midnight to 4:00 am) where Maximum Ramp Rate Upward is [TBD] MW/minute. Maximum Ramp Rate Downward of [TBD] MW/minute for all periods except during Evening Periods (typically 4:00 pm to 8:00 pm)where Maximum Ramp Rate Downward is [TBD] MW/minute.
Ramp Rates. (a) In the event that either Party anticipates a significant change to the Actual Flow Rate then that Party will notify the other Party as soon as is reasonably practicable and the Parties will co-operate in defining mutually acceptable ramp rates.
Ramp Rates. (i) Seller shall ensure that the ramp rate of the Facility is less than the following limits for all conditions other than those under control of the Company System Operator or those due to desired frequency response, including start up, changes in the solar resource, and shut down for the following periods as calculated in accordance with Attachment C (Methods and Formulas For Measuring Performance Standards). Maximum Ramp Rate Upward of 2 MW/minute for all periods of uncoordinated changes in output in response to changes in resource. Maximum Ramp Rate Downward of 2 MW/minute for all periods of uncoordinated changes in output in response to changes in resource. Maximum ramp rate for shutdown/startup other than requested by System Operator (such as high wind speed shutdown, startup due to resource availability) 2 MW/minute. Plant operator should notify System Operator of equipment startup/shutdown by method agreed by Company.
