6.3.22 Shell Lake Area

Tracking Number: 2009-NE-N9

Utility: Great River Energy

Inadequacy: GRE member cooperative Itasca-Mantrap Cooperative Electrical Association has requested interconnection of a new Shell Lake distribution substation on the west side of its service territory. The existing distribution system cannot reliably serve the area load growth.

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

Alternatives. The Osage-Pine Point 34.5 kV line offers the only source to this area. The load delivery point is expected to be between three and five miles from this facility.

Analysis. This is the least cost distribution plan in the Itasca-Mantrap analysis. GRE is obligated to provide a source to the new distribution site whereby the Osage-Pine Point line is the nearest and only viable line to interconnect the new substation. Any transmission to this area will be constructed to 115 kV standards for potential future conversion (see Park Rapids Area, Tracking Number 2009-NE-N7).

Schedule. GRE will coordinate with the Itasca-Mantrap Cooperative to see when the new substation needs to be energized. The best estimate is that the new facilities will be required in 2015.
