- 6 - <br /> supplemental power supply to 57 of its member systems, all of which are located within <br /> the MAPP region. MRES also engages in short-term energy transactions from its <br /> generation resources. Many of its members are surrounded by and dependent on <br /> transmission facilities owned by MISO transmission owners, and thus are directly <br /> impacted by the policies and procedures established by MISO. <br /> Southern Minnesota Municipal Power Agency ("SMMPA") is a joint action <br /> agency comprising 18 member municipalities in Minnesota which own and operate <br /> municipal electric systems. SMMPA is a non-profit political subdivision of the State of <br /> Minnesota organized under Chapter 453 of the Minnesota Statutes. SMMPA functions as <br /> the principal power supplier for its members and met the 529 MW 2011 peak load of its <br /> members with 678 MW of generating resources owned by SMMPA or its members and a <br /> portfolio of power purchases from other sources, including an allocation of power from <br /> the Western Area Power Administration. SMMPA is a MISO Market Participant. <br /> SMMPA owns over 291 miles of transmission lines ranging from 69 kV to 230 <br /> kV that are integrated with those of other members of MISO, as well as several <br /> transmission substations at varying transmission voltages, reflecting an investment of <br /> approximately$145 million in facilities integrated in the MISO grid. Although it owns <br /> portions of the network representing significant contributions to the regional grid, and <br /> although SMMPA is itself a MISO Transmission-Owning Member with a transmission <br /> ownership area, SMMPA is transmission-dependent upon the facilities of other MISO <br /> members because many of SMMPA's members are located in the transmission ownership <br /> areas of Xcel Energy, ITC Midwest, and Great River Energy. <br /> 125 <br />
