Common use of Islanding Protection Clause in Contracts

Islanding Protection. The system must trip off-line and remain off-line in the event of a fault on the customer’s system or loss of source on the City’s electric system. Physical requirements: The customer’s over-current protective device at the service panel must be dedicated and must be capable of interrupting the maximum available fault current and shall be clearly marked to indicate power source and connection to the City’s electric system. Customer is required to provide CES a readily accessible solid blade disconnect switch adjacent to the service point on the exterior of the building suitable for a utility lock. As determined by CES, the switch must meet “visible air gap” requirements, be placed at an approved location, be dedicated to utility, permanently marked “GENERATION DISCONNECT”, and must be capable of interrupting the maximum available fault current of customer’s distributed generation system. Renewable energy credits: They City may accept, but is not obligated to accept, renewable energy credits from the customer. If customer anticipates transferring renewable energy credits to the City, an approved meterbase must be installed adjacent to the above mentioned disconnect suitable for a City meter (production meter). CES shall own the production meter and CES shall measure electricity produced during the billing cycle. Inspection and disconnection: CES reserves the right to inspect and test customer’s equipment at any time to ensure proper operation, compliance with safety requirements, or compliance with power quality requirements. CES may separate customer generation from utility system when, as determined by CES, customer system is unsafe or not in compliance. CES reserves the right to separate customer generation from utility system when, as determined by CES, continued parallel operation with distribution system is unsafe or may cause damage to persons or property or when working on de-energized lines to isolate all sources of generation. If utility service to customer is disconnected for any reason, distributed generation service will also be disconnected. CES shall not be liable to any person, directly or indirectly, for loss of property, injury, or death resulting from the interconnection of a cogenerator or distributed generation facility to its electrical system.
