Frequency Response. Seller shall comply with the requirements of Section 1(g)(xi) (Frequency Response (DROOP)), Section 1(g)(xii) (Dynamic Active Power – Frequency Performance), and [FOR FACILITIES WITH STORAGE] Section 1(g)(xiii) (Alternate Active Power / Frequency Response Modes) of this Attachment B (Facility Owned by Seller).
Frequency Response. Seller Facility shall provide a primary frequency response with a frequency droop characteristic reacting to system frequency fluctuations at the Point of Interconnection in both the overfrequency and underfrequency directions except to the extent such response is not operationally possible because of the level of available solar resource and depletion of energy storage. The Facility frequency response control shall adjust, without intentional delay and without regard to the ramp rate limits in Section 3(c) (Ramp Rates) of this Attachment B (Facility Owned by Seller), the Facility's net real power import or export when system frequency is not 60 Hz based on frequency deadband and frequency droop settings specified by the Company. The Facility frequency response control shall be allowed to increase the net real power import or export above the Power Reference Set Point set under Section 1(g)(viii) of this Attachment B (Facility Owned by Seller) or further decrease the net real power import or export from the Power Reference Set Point in its operations. The frequency deadband shall be settable in the range from +/-0.01 Hz to +/- 0.10 Hz and the frequency droop shall be settable in the range of 0.1% to 10%. The Facility frequency response control shall be in continuous operation when the Facility is online and connected to the Company unless directed otherwise by the Company.
Frequency Response. Seller shall comply with the requirements of Section 1(g)(xi) (Frequency Response (DROOP)), Section 1(g)(xii) (Dynamic Active Power – Frequency Performance), and [FOR FACILITIES WITH STORAGE] Section 1(g)(xiii) (Alternate Active Power / Frequency Response Modes) of this Attachment B (Facility Owned by Seller). Round Trip Efficiency. The round trip efficiency of the XXXX as measured at the POI shall be not less than [________] percent ([___]%). [ND: The percentage for round trip efficiency should be taken from Seller’s response to the RFP.]
Frequency Response. If Purchaser elects to take delivery of Purchaser’s Output via a pseudo tie, frequency response is included in Purchaser’s Output as part of the real-time control error, which occurs in response to frequency events, and is allocated to purchasers. Purchaser maintains responsibility for frequency response obligations within Purchaser’s BA. This Contract does not create a right for Purchaser to receive Transferred Frequency Response to meet any NERC reliability obligations including, but not limited to, Frequency Response Obligation under BAL 003.

Frequency Response. Seller Facility shall provide a primary frequency response with a frequency droop characteristic reacting to system frequency fluctuations at the Point of Interconnection in both the overfrequency and underfrequency directions except to the extent such response is not operationally possible because of the depletion of energy storage.
Frequency Response. Seller Facility shall provide a primary frequency response with a frequency droop characteristic reacting to system frequency at the Point of Interconnection in both the overfrequency and underfrequency directions except as limited by the minimum and maximum available capacity at the time of the event. Minimum operational limit for each online turbine is to be supplied. Nominal System Frequency is 60.00 Hz. The droop setting should permit a setting from 0.1 to 10%. This setting shall be changed upon Company’s written request as necessary for grid droop response coordination. The droop setting shall be tunable and may be specified during commissioning, the nominal setting is 4%. The Seller shall make commercially reasonable efforts to provide frequency response without an intentional deadbandbut in any case is not to exceed +/- 0.0166 Hz . The droop response shall provide [80-100%] of expected (proportional) active power output at the end of a linear ramp change in frequency of [1% (0.6 Hz)] over a [5] second period starting at the initial frequency deviation. . [80%] of the desired response has to be delivered within [2] seconds after disturbance, and full response must be deployed within an additional [3] seconds after an initial [2] seconds for a total response within [5] seconds after the disturbance. When operating in parallel with the Company System, the Facility shall operate with its speed governor control in automatic operation. Notification of changes in the status of the speed/load governing controls must be provided to the Company System Operator immediately preferably through SCADA. The Facility frequency response control shall adjust, without intentional delay and without regard to the ramp rate limits in Section 3(c)(Ramp Rates) of this Attachment B (Facility Owned by Seller), the Facility's net real power export when system frequency is not 60 Hz based on frequency deadband and frequency droop settings specified by the Company. The Facility frequency response control shall be allowed to increase the net real power export above the Power Reference Limit set under Section 1(g)(viii) of this Attachment B (Facility Owned by Seller) or further decrease the net real power export from the Power Reference Limit in its operations. The Facility frequency response control shall be in continuous operation when the Facility is exporting energy to the Company unless directed otherwise by the Company.
Frequency Response. To the extent that excessive deviation is a result of BWP frequency response, applicable Second and Third Deviation Band charges or credits shall be waived for the period of the frequency excursion. The excluded deviation charges or credits will be calculated at 5 MW per 0.1 Hz, provided that the initial frequency disturbance is greater than +/- 0.06 Hz. If BWP chooses TLB, this Section 8 shall not apply, but this Section 8 will apply if BWP elects NTD.
Frequency Response. 4The crest factor of a Watt-hour meter is often provided for both current and voltage. For current, it is the ratio of the peak current to the RMS current in a specific current range. When only one crest factor is given, it is usually for current. An average True RMS Watt-hour meter has a crest factor in the range of 2:1 to 6:1. Another issue to consider when selecting a Watt-hour meter is the frequency response rating of the meter. Electronic equipment that contains switching power supplies causes harmonics (odd harmonics typically up to the 21st). These harmonics must be accounted for in measurement, or the energy and power consumption will be inaccurate. Accordingly, EPA recommends that manufacturers purchase Watt-hour meters that have a frequency response of at least 3 kHz. This will account for harmonics up to the 50th, and is recommended by IEC 555. Resolution Manufacturers will probably want a meter that can provide resolution of 0.1 W. Accuracy Another feature to consider is the resulting accuracy that can be achieved. Catalogues and specification sheets for Watt-hour meters typically provide information on the accuracy of energy and power readings that can be achieved at different range settings. When measuring a product that is very close to the MOU specifications, Partners will need to set up a test that will provide greater accuracy. For example, if the resulting accuracy for a Watt-hour meter at the test settings is + 0.5 W, then be sure the measured power consumption of the MFD or upgradeable digital copier is within at least 0.5 W of the MOU specification. Calibration Watt-hour meters should be calibrated every year to maintain their accuracy. QUESTIONS AND ANSWERS REGARDING TESTING PROCEDURES FOR ENERGY STAR® MULTIFUNCTION DEVICES AND UPGRADEABLE DIGITAL COPIERS Q: Are these testing requirements mandatory?
