Common use of Determination of Measured Power Curve Clause in Contracts

Determination of Measured Power Curve. During the first Contract Year, the Seller shall collect data to create a Measured Power Curve for each WTG that will be used for the remainder of the Initial Term to calculate the Expected Generation. The Measured Power Curve for each WTG will not be updated. To develop the Measured Power Curve for each WTG, Seller shall use data for such WTG during periods when such WTG is in the operational state categorized as CTH excluding periods where the WTG’s operational state is categorized as ERSDTH, EFDTH, EMPTH, EPDTH, oEFDTH, oMPTH, oEPDTH, or Environmental Derate. See Exhibit Q.3 Following the end of the first Contract Year, the Measured Power Curve for each WTG shall be calculated by Seller using the following data from the first Contract Year: (aa) the Density-Adjusted Wind Speed (for avoidance of doubt, the only referenced air density shall be the ISO standard atmosphere for sea level air density of 1.225 kg/ as set forth in Section 3 (Calculation of Density-Adjusted Wind Speed) of this Attachment Q) (Calculation of Certain Metrics), (bb) the 10-minute averaged Measured Wind Speed and (cc) the 10-minute averaged power output of such WTG. The data set used for calculating the Measured Power Curve shall include only Measured Wind Speed and power output measurements during the periods specified in the second bullet point above. The Measured Power Curve shall be calculated using (i) 0.5 m/s wind bins ranging from 1 below the manufacturer's specified cut-in-wind speed to, at least, 1.5 times the wind speed specified by the manufacturer as associated with 85% of the rated power of the WTG and (ii) the 10-minute averaged power output for each wind speed bin. The data set used to calculate the Measured Power Curve should include a minimum of 180 hours of sampled data from periods during the preceding Contract Year, where each wind bin includes the minimum of 30 minutes of sampled data, i.e. a minimum of 3 data points. If the aforementioned required minimums of sampled data are not available, Seller and Company may agree in writing upon a smaller data set to calculate the Measured Power Curve. Except as necessary to satisfy the foregoing requirements of this Section 4 (Determination of Measured Power Curve) of this Attachment Q (Calculation of Certain Metrics), the Measured Power Curve shall be calculated in a manner consistent with Clause 8.1 and Clause 8.2 of IEC 00000-00-0. Upon Seller's calculation of the Measured Power Curve for each WTG as provided in this Section 4 (Determination of Measured Power Curve), Seller shall provide written notice to Company of such Measured Power Curve(s).
