The reliability of electricity distribution to further improve for some 30,000 customers in southwestern Finland and urban areas in Satakunta in the next few years
Caruna is moving to the next phase in weatherproofing its electricity distribution network: underground cabling of low-voltage networks in urban areas. The first step is to lay underground cabling in urban areas in southwestern Finland and Satakunta. The partner for the network improvement project has been selected, and Eltel Networks Oy will join Caruna in renewing and improving networks during the next four years.
Caruna continues renewing its electricity network and improving distribution reliability in southwestern Finland and Satakunta. This network improvement project is the first of its kind and will improve the reliability of electricity distribution for the 30,000 customers in the area. In order to minimize the inconvenience to inhabitants and future renovation needs in the area, the aim of the project is to combine as much electricity, street lighting and fiber network construction as possible.
The total value of the investment is approximately MEUR 25. The contract period with our partner is four years. During this time, some 900 kilometers of overhead cable will be replaced by weatherproof underground cable. This includes 700 kilometers of low-voltage network and 200 kilometers of medium-voltage network. The medium-voltage network with 20kV distributes electricity to both small industries and supply transformers located near inhabited areas. The low-voltage network (0.4kV) connects households to the electricity distributor's supply network.
“The plan is to build the network to also serve people with electric cars and small-scale producers of renewable energy in the decades to come,” says Tomi Yli-Kyyny, Caruna CEO.
Construction work to start in 2019
The planning of the project will start this autumn, and construction is expected to start in the spring of 2019. The main focus of construction will be in underground cabling of low-voltage networks. The networks will be moved underground, which will reduce power outages caused by storms and snow in the future.
The structural and technical properties of the electricity network will also be improved. In the event of a failure, the failure can be isolated and electricity distribution can be quickly restored in undamaged parts of the network.
