6.3.23 Aitkin Area

Tracking Number: 2009-NE-N10

Utility: Great River Energy

Inadequacy: GRE member cooperative Mille Lacs Energy Cooperative has requested interconnection of a new Iron Hub distribution substation on the west side of Aitkin. The existing distribution system is becoming unable to serve the area load growth.

A map of the area is shown on the following page.

Alternatives. The Riverton-Cromwell 115 kV line offers the only transmission source to this area. The load delivery point is expected to be about three miles from this transmission line.

Analysis. This is the least cost distribution plan in the Mille Lacs Energy analysis. GRE is obligated to provide a transmission line to the new distribution site whereby the Riverton-Cromwell 115 kV line is the nearest and only viable transmission line to interconnect the new substation.

Schedule. GRE will coordinate with Mille Lacs Energy to see when the new substation needs to be energized. The best estimate is that the new facilities will be required in 2014.
