Common use of Study Scope Clause in Contracts

Study Scope. The scope of this study is limited to evaluating the project’s impact on the following four items as listed in Section 6.0 of Appendix 6 of Attachment Z: 6.1-Initial identification of circuit breaker short circuit capability limits; 6.2-Initial identification of thermal overload or voltage limit violations; 6.3- Initial review of grounding requirements and system protection; and, 6.4-Description and non-binding estimated cost of facilities required to interconnect the proposed Small Generator Facility and to address the identified short circuit and power flow issues. The scope of this study provides the results of: • Initial identification of thermal overload or voltage limit violations (steady state) for summer and winter peak loading conditions • Sensitivity study (steady state only) to assess the impact of the project during light load conditions • Analysis on models with and without the project, in order to evaluate the impact of the project on the bulk and local power network • Available 13.2kV system characteristics on a 100MVA base at each 13.2kV delivery point to each of the 3 customer service locations • Recommended interconnection configuration with a list of system upgrades required • Initial identification of circuit breaker short circuit capability limits • Initial review of system protection requirements to be included for the Company’s system and those at the generation facility/customer service points • List of system protection upgrades required Madison County LFGTE Interconnection Study rev11 21 2008.doc rev.
