C.4PX2020 <br />INTERIM REPORT <br />DECEMBER 2004 <br />L,a~, au, i - r.as,ern nias <br />Transmission improvements identified in the 2003 Minnesota Biennial Transmission Plan are <br />included in the CapX 2020 base model. The plan is available at www.nlinnclccn•ans.co~li. <br />STUDY ANALYSIS <br />The technical team will test several transmission solutions for each generation scenario and <br />will perform steady-state power flow analysis (first contingency simulations) to determine <br />which transmission solution eliminates thermal overloads on transmission greater than 100 <br />kilovolts in the region. The team also will perform voltage analysis for each of the <br />transmission solutions. <br />The technical team plans to incorporate transmission alternatives identified in on-going <br />studies in conjunction with transmission plans identified by various transmission <br />stakeholders. The goal is to identify transmission improvements that bring remote generation <br />to the load-serving centers in the region and develop an expanded transmission backbone that <br />supports continued load growth in the various load centers. The transmission improvements <br />will focus on high voltage solutions (345 kilovolt lines and 500 kilovolt lines) that best <br />address the various generation scenarios, as shown in Diagram 8. <br />27 <br />
