Relative Costs When Life Cycle Issues are Included

Comparing basic up front costs between cables and OHLs:

Cabled section length (km) 5 10
Capex/km XLPE cable €k[1] 9,678 8,845
Capex/km OHL €k 1,522 1,522
Cost ratio – cable cost ÷ OHL cost 6.4 5.8

When different life cycle factors are included in the 5km example:

Life cycle costs for 5km sections XLPE ÷ OHL
Discounted present cost at 3% discount rate (DPC) 6.4
DPC including maintenance & decommissioning 6.1
DPC including maintenance, decommissioning & losses 4.0
