Design Limits. Developer shall have equipment that will allow it to supply its Reactive Power (MVAR’s) requirements and simultaneously supply capacity and energy to the Utility’s Grid with a power factor of 0.80 lagging. • The Facility shall be able to operate at frequencies between 57.7 and 63 hertz, outside which the Developer shall separate the Facility from the Utility’s Grid. • The voltage at the Interconnection Point shall be maintained at 13,800 volts +/- 5%. Voltage fluctuations may be noticeable as visual lighting variations (flicker) and can damage or disrupt the operation of electronic equipment. IEEE Standard 519 and IEC 61000-3 provide definitions and limits on acceptable levels of voltage fluctuation. Loads or system connections to the Utility’s Grid shall comply with the limits in these standards. • Power quality Design considerations should include applicable standards including, but not limited to IEEE Standards 142, 519, 1100 1159, 1547, and ANSI C84.1. Harmonic distortion has to be compliant with IEC ▇▇▇▇▇-▇-▇▇. • Reactive Power Each entity shall provide for its own Reactive Power requirements, at both leading and lagging Power Factors unless otherwise specified by parties. Utility might require Developer to minimize exchange of Reactive Power with Utility’s system, especially under peak load conditions. This can be accomplished by installing equipment to allow matching of internal supply and demand of Reactive Power. •Developer shall advise Utility of any operating constraints and limits, which may from time to time, apply to the Facility.
