Project in Norway
Construction of the 420kV transmission line Skareheia(Evje)-Holen.
Works on this project are divided into two parts. Expected start of works is September 2007, with completion planned by August 2009. The investor is a Norwegian state company Statnett.
Due to extremely difficult weather conditions and a poorly developed road infrastructure, works will be carried out with the assistance of helicopters. Works will be carried out at extremely low temperatures, in inaccessible locations, with up to three meters of snow. Meaning that the approach to this new organization of carrying out works will be performed by helicopters, which will be a real challenge. This will be the largest such structure built under such conditions by Dalekovod.

Project in Albania
The works investor on the project for the construction of the 400kV transmission line Tirana-Podgorica is KESH-OST (operator of the carrier system) from Albania and Elektroprivreda Montenegro, with the contractor being Dalekovod d.d. The project is contracted as a turn key solution.
The technically demanding project consists of an aerial double OHL 400kV line with a length of 76.14km, and a single air section 400kV line with a length of 80.80km. Besides the transmission line, this project includes the construction of a 400kV conductor field in the existing transformer station 400/210kV Elbasan 2, and two 400kV conductor fields in the transformer station 400/220kV Podgorica 2.
The deadline for completion of works in 24 months starting from the date of the advance payment.
| Length of transmission line: | double OHL – 76.14km | |||
