If synchronous operation through any line becomes interrupted either manually or automatically for any reason, including scheduled maintenance that has been agreed to by the parties, the parties shall cooperate to remove the cause of the interruption and restore the Line to normal operating condition as soon as practicable. No party shall be liable to any other party for any damage or loss of revenue caused by any such interruption. All circuit breakers and associated terminal facilities shall be operated by the party that owns such facilities. ARTICLE 3 METERING POINTS AND METERING Metering Points 3.01 Suitable metering equipment shall be provided, owned, and maintained by the owners thereof at the metering points and voltages as hereinbelow set forth, and at such other points and voltages and with such ownership as may be agreed upon by the parties: 3.011 Should Gibson Unit #5 or other generation which would affect losses be installed, located of the metering shall be reviewed. 3.012 In respect of the X Interconnection Point, 345,000-volt metering equipment owned by Indianapolis Company and installed at Indianapolis Company's Sunnyside Substation, subject to being moved pursuant to Section 10.01 to Interconnection Point Z, at Indianapolis Company's expense and to be installed in Service Company's Carthage Substation for the purpose of monitoring the flows in the Sunnyside-Carthage Line. 3.013 In respect of the Y Interconnection Point, 345,000-volt metering equipment owned by Indianapolis Company and installed at Indianapolis Company's Petersburg Station.
