Aerators Variable Frequency Drives Sample Clauses

Aerators Variable Frequency Drives. Option A is the selected approach for the aerators variable frequency drives ECM measurement and verification plan and performance assurance. This ECM includes the addition of dissolved oxygen sensors and two VFDs to modulate the motor speed in order to maintain proper levels of dissolved oxygen in aeration basins. The energy analysis parameters used to verify savings and assure performance are: M&V Option Parameters BASELINE POST-INSTALLATION Motor speed % Actual speed Stipulated Motor Amperage Instantaneous amperage reading Calculated based on motor speed ratio and affinity laws Motor Voltage Instantaneous voltage reading Stipulated, same as baseline Motor Power Factor Name plate data Name plate data Hours of Operation Stipulated Stipulated Energy Consumption Calculated Calculated Demand Consumption Calculated Calculated Energy Rate Stipulated rate schedule Stipulated rate schedule Demand Rate Stipulated rate schedule Stipulated rate schedule To validate the estimated savings of the equipment after the installation is complete, ESG will measure the following: - Data log the system amperage over a two-week period to verify it is working within the stipulated parameters. The information obtained will be used to verify the savings as shown in savings calculations for the aerators variable frequency drives ECM in Exhibit BAttachment 1. To assure the performance of the installed equipment ESG will: - Validate installed equipment and control sequences to meet specifications. - Validate installed equipment and control sequences to operate and perform as specified.

  • Under-Frequency and Over Frequency Conditions The New York State Transmission System is designed to automatically activate a load- shed program as required by the NPCC in the event of an under-frequency system disturbance. Developer shall implement under-frequency and over-frequency relay set points for the Large Generating Facility as required by the NPCC to ensure “ride through” capability of the New York State Transmission System. Large Generating Facility response to frequency deviations of predetermined magnitudes, both under-frequency and over-frequency deviations, shall be studied and coordinated with the NYISO and Connecting Transmission Owner in accordance with Good Utility Practice. The term “ride through” as used herein shall mean the ability of a Generating Facility to stay connected to and synchronized with the New York State Transmission System during system disturbances within a range of under-frequency and over-frequency conditions, in accordance with Good Utility Practice and with NPCC Regional Reliability Reference Directory # 12, or its successor.

  • Provisioning of High Frequency Spectrum and Splitter Space 3.2.1 BellSouth will provide <<customer_name>> with access to the High Frequency Spectrum as follows:

  • Network Interconnection Architecture Each Party will plan, design, construct and maintain the facilities within their respective systems as are necessary and proper for the provision of traffic covered by this Agreement. These facilities include but are not limited to, a sufficient number of trunks to the point of interconnection with the tandem company, and sufficient interoffice and interexchange facilities and trunks between its own central offices to adequately handle traffic between all central offices within the service areas at P.01 grade of service or better. The provisioning and engineering of such services and facilities will comply with generally accepted industry methods and practices, and will observe the rules and regulations of the lawfully established tariffs applicable to the services provided.

  • Access Toll Connecting Trunk Group Architecture 9.2.1 If CBB chooses to subtend a Verizon access Tandem, CBB’s NPA/NXX must be assigned by CBB to subtend the same Verizon access Tandem that a Verizon NPA/NXX serving the same Rate Center Area subtends as identified in the LERG.

  • Commercial Price List Reductions Where NYS Net Prices are based on a discount from Contractor’s list prices, price decreases shall take effect automatically during the Contract term and apply to Purchase Orders submitted on or after the date Contractor lowers its pricing to its customers generally or to similarly situated government customers during the Contract term; or

  • Shift Rotation Routine shift rotation is not an approach to staffing endorsed by the Employer. Except for emergency situations where it may be necessary to provide safe patient care, shift rotation will not be utilized without mutual consent. If such an occasion should ever occur, volunteers will be sought first. If no one volunteers, the Employer will rotate shifts on an inverse seniority basis until the staff vacancies are filled.

  • Primary Frequency Response Developer shall ensure the primary frequency response capability of its Large Generating Facility by installing, maintaining, and operating a functioning governor or equivalent controls. The term “functioning governor or equivalent controls” as used herein shall mean the required hardware and/or software that provides frequency responsive real power control with the ability to sense changes in system frequency and autonomously adjust the Large Generating Facility’s real power output in accordance with the droop and deadband parameters and in the direction needed to correct frequency deviations. Developer is required to install a governor or equivalent controls with the capability of operating: (1) with a maximum 5 percent droop ± 0.036 Hz deadband; or (2) in accordance with the relevant droop, deadband, and timely and sustained response settings from an approved Applicable Reliability Standard providing for equivalent or more stringent parameters. The droop characteristic shall be: (1) based on the nameplate capacity of the Large Generating Facility, and shall be linear in the range of frequencies between 59 and 61 Hz that are outside of the deadband parameter; or (2) based on an approved Applicable Reliability Standard providing for an equivalent or more stringent parameter. The deadband parameter shall be: the range of frequencies above and below nominal (60 Hz) in which the governor or equivalent controls is not expected to adjust the Large Generating Facility’s real power output in response to frequency deviations. The deadband shall be implemented: (1) without a step to the droop curve, that is, once the frequency deviation exceeds the deadband parameter, the expected change in the Large Generating Facility’s real power output in response to frequency deviations shall start from zero and then increase (for under-frequency deviations) or decrease (for over-frequency deviations) linearly in proportion to the magnitude of the frequency deviation; or (2) in accordance with an approved Applicable Reliability Standard providing for an equivalent or more stringent parameter. Developer shall notify NYISO that the primary frequency response capability of the Large Generating Facility has been tested and confirmed during commissioning. Once Developer has synchronized the Large Generating Facility with the New York State Transmission System, Developer shall operate the Large Generating Facility consistent with the provisions specified in Articles 9.5.5.1 and 9.5.5.2 of this Agreement. The primary frequency response requirements contained herein shall apply to both synchronous and non-synchronous Large Generating Facilities.

  • Fire Fighting Costs of operating and maintaining the fire-fighting equipments and personnel, if any.

  • Emergency Childcare Employees may use vacation leave for childcare emergencies after the employee has exhausted all of their accrued compensatory time. Use of vacation leave and sick leave for emergency childcare is limited to a combined maximum of four (4) days per calendar year.

  • Provisioning Line Splitting and Splitter Space 3.8.1 The Data LEC, Voice CLEC or BellSouth may provide the splitter. When EZ Phone or its authorized agent owns the splitter, Line Splitting requires the following: a non-designed analog Loop from the serving wire center to the NID at the End User’s location; a collocation cross connection connecting the Loop to the collocation space; a second collocation cross connection from the collocation space connected to a voice port; the high frequency spectrum line activation, and a splitter. The Loop and port cannot be a Loop and port combination (i.e. UNE-P), but must be individual stand-alone Network Elements. When BellSouth owns the splitter, Line Splitting requires the following: a non designed analog Loop from the serving wire center to the NID at the End User’s location with CFA and splitter port assignments, and a collocation cross connection from the collocation space connected to a voice port.
