OPERATING CONDITIONS. Developer shall design the Merchant Transmission Facility to operate within the voltage guidelines as specified in Article 9.5. 2. The nominal frequency of the New York State Transmission System is 60 Hz. The frequency may deviate by ± 0.05Hz from the nominal value during normal steady-state conditions. During extreme system disturbances, the system frequency may deviate from the nominal value by ± 0.07Hz. For very extreme disturbances such as system separation, frequency deviations may be ± 1.5Hz. Connecting Transmission Owner typically operates the 345kV AC bus at a higher voltage than 1.0pu. Under infrequent operating conditions the system voltage may be reduced to less than 1.0pu and the system reactive requirements may be such that the Merchant Transmission Facility may reduce import levels during such conditions.
