Voltage, Frequency, Harmonic and Flicker levels as defined in IEEE 1547 D l 1 standard during periods when the Customer Generator is operated in parallel with the Distribution System. (2)With Extended Parallel Operation, the Customer Generator is paralleled with the Distribution System in continuous operation. Special design, coordination and agreements are required before any extended parallel operation will be permitted. An interconnection study will need to be performed by ERMU to identify the issues involved. Protective devices are required to permit safe and proper operation of the Distribution System while interconnected with Customer Generator. In general, an increased degree of protection is required for a larger Customer Generator due to the greater magnitude of short circuit currents and the potential impact to Distribution System stability. Larger installations may require more sensitive and faster protection to minimize damage and ensure safety. Customer shall provide protective devices and systems to detect the Voltage, Frequency, Harmonic and Flicker levels as defined in IEEE 1547 D l 1 standard during periods when the Customer Generator is operated in parallel with the Distribution System. Section 4: Power Quality. Operation of Customer Generator and auxiliary equipment must not cause any reduction in the quality of service provided by ERMU to its customers nor interfere with the operation of ERMU's Distribution System or ERMU's power supplier's transmission system. The equipment shall not put any undesirable voltages, frequencies, or transients on to ERMU's Distribution System or ERMU's power supplier's transmission system. If any of the aforementioned events occur,the equipment shall be disconnected until such time as the harmful conditions have been corrected. Customer shall be responsible for taking any corrective action that may be required and/or reimbursing ERMU for the cost of corrective action which ERMU deems necessary to provide and restore services to prescribed limits. The Customer Generator will generate 3 phase, 60 hertz power when interconnected to ERMU's Distribution System at normal 12.47 Kv at a power factor of 95% lagging. Total Harmonic Distortion(THD) levels produced by the equipment shall be less than 1%in compliance with standards as defined by IEEE 519-1992. ARTICLE 5. INSURANCE. Customer shall maintain general liability insurance for the term of this agreement from a qualified insurance agency with a B+ or better rating by "Best" and with a combined single limit of not less than: 1) Two million dollars ($2,000,000) for each occurrence if the gross nameplate rating of the generation system is greater than 250 kW. 2) One million dollars (1,000,000) for each occurrence if the gross nameplate rating of the generation system is between 40 kW and 249 kW. Such general liability insurance shall include coverage against claims for damages resulting from i)bodily injury, including wrongful death; and(ii)property damage arising out of the customer's ownership and/or operation of the generation system under this agreement. 6 136
