Avineon to provide GIS services to NorthWestern Energy

Alexandria, VA, March 3, 2009 — Avineon Inc. announced NorthWestern Energy has awarded the company a GIS data clean-up and realignment services contract. Avineon will be responsible for realigning overhead and underground electric facilities as well as gas facilities and NorthWestern’s specific land-base information to a state-wide cadastral land-base.

NorthWestern Energy serves approximately 640,000 customers in Montana, South Dakota, and Nebraska. As part of the data manipulation project, Avineon will convert the electrical overhead facility model from a super-span type to a pole and structure span model. The company will also be responsible for capturing new GPS structures and populating GPS coordinates and pole numbers to the existing structures, creating and updating connectivity, establishing relationships between conductors and corresponding poles and structures, as well as generating a customer point of service associating the customer to its respective transformer, service pedestal or gas line. Avineon is also capturing NorthWestern Energy’s daily backlogs, updating the realigned data, and providing updates to NorthWestern Energy within a two week period to reduce the overall GIS backlog.

In addition to facility realignment and network modifications, Avineon will merge additional attributions gathered in the field with existing pole data stored in NorthWestern Energy’s GIS. Currently the data resides in the Intergraph G/Technology platform.
