Common use of Supply System Reclosing Clause in Contracts

Supply System Reclosing. The Generator-Owner is responsible to ensure their generation source is disconnected before the Company’s feeder breaker or line sectionalizer recloses for protecting against faults on the 13.2kV distribution system. The Company’s reclose time for Feeder #50150 is 15 sec. [This means that the system will reclose in 15 sec whether the generation is off or on]. Note that the Company would have to lose 3 lines and the tie breaker at Oneida Substation. [The only time that would happen is on a bus fault or a breaker failure of the tie breaker, therefore, the Project can ignore the reclosing times on the 115 kV.] Madison County LFGTE Interconnection Study rev11 21 2008.doc rev. Nov. 21, 2008 Service Agreement No. 1988 Interconnection Study: Madison County Landfill Gas to Energy 2 MVA Small Generating Facility The Company assumes no liability for the Generator-Owner’s system if this is not observed by the generator protective controls. The Generator-Owner needs to understand that if the Company’s system recloses and they are still online, the systems will most likely be out of synch and the Generator- Owner’s generation could sustain major damage and damage to other customer connected equipment may occur. Additionally, if the Generator-Owner’s generator causes disturbances to others, then they are subject to disconnection per ESB 756 Appendix A Section 5.2, ESB 750 Sections 3 and 11, and the Company's tariff, PSC No. 207. Subsequently, the Generator-Owner may be responsible to compensate for any damages. As changes occur to the Company’s system these reclose settings are subject to change by the Company according to its utility practice. The Generator-Owner is responsible for maintaining their own equipment coordination with the Company’s system at their cost. There is no notification requirement in place for the Company’s changes of reclosing settings. The Generator-Owner needs to communicate with the Company upon their relay coordination maintenance schedule (see ESB 755) for information necessary to update their studies. There are serious safety concerns such as, if the station breaker is manually opened, it is possible that the generation would continue to energize the circuit while utility personnel may assume that the circuit is de-energized and safe. Also, if the Small Generating Facility (SGF) is able to island with the connected load, there will be an out of synch close condition on the Oneida Station feeder breaker when trying to close. The station breaker cannot be closed until the SGF has been tripped off. Currently there is no synchronism or voltage check on the Oneida Station breaker, R500, for closing conditions. It is recommended for this project to include adding at least a voltage check relay to the station breaker and at the new feeder recloser (item 4.1.1 above) for close supervision.
