Battery System. The newly proposed recloser shall be equipped by Interconnection Customer with integral, manufacturer-provided batteries for open and closing energy. However, the remainder of the battery support throughout the entire electrical generation and relaying systems throughout the plant shall be provided in detail, along with alarm drawings and an explanation of the various alarms and the conditions by which they alarm. Relay power and tripping power is required to be from a DC source. The AC source for battery power is typically required to be powered from a source located on the utility side of the customer high side three phase interrupting device. The design of the facility is to be such that it incorporates fail safe provisions to provide for tripping the generation from the EPS for loss or degradation of DC to protective relays, loss of protective relay power supplies, and loss or degradation of tripping power to the required interrupting devices. A review of the single line diagram does show multiple sources to the AC power panels including a backup generator. The one-line diagram does not show the source of the battery charging circuit. The one-line diagram does not show that a fail-safe design is being provided. These features shall be clearly demonstrated on the future Stage B technical submittals to be provided to the Connecting Transmission Owner. Battery system maintenance records shall be provided to the Connecting Transmission Owner for their review. Where no such recent maintenance records exists, the battery system shall be tested and certified by a qualified third party contractor. Battery chargers shall also be reviewed and confirmed for adequacy and suitability to the existing battery supply system.
