OPERATIONS EXPERIENCE

Lower yearly production than expected

More repair work of main components than expected

High availability achieved

Positive experience with internalizing the O&M work

Synergies between hydro and wind

Introduction of WMS

Plan to introduce the Day 1 concept over the next few years

Grid tariffs extremely high in certain regions Eg) Kjøllefjord in Finnmark

CURRENT MAIN O&M FOCUS - RDS-PP AND RCM

Taken important decision to implement RDS-PP to all wind power plants in Norway in 2009.

Summer 2010 starting to convert old EBL code to RDS-PP.(110 000 tag)

Post converting to RDS-PP, RCM methodology introduced.
