3 Environmental performance BASEd on LCA The results for distribution (Downstream process) of generated electricity have been compiled as follows: • Environmental impact from operation of electricity networks has been inventoried and divided by the total amount of electricity distributed in that specific network. • The length (km) of different distribution networks has been inventoried and multiplied by the environmental impact for construction per km and divided by the total amount of electricity distributed in the specific network • Environmental impact from distribution losses of 3 % has been calculated through multiplication of total environmental impact of generation above with 0,03.

3 Environmental performance BASEd on LCA 3.3 Environmental information – based on LCA The assessment results are summarised in the Ecoprofile below and commented in the chapters 3.3.1–3.3.8. • For Upstream process, Core process, Core process- infrastructure, and Total generated the numbers are expressed per 1 kWh generated electricity. • For Downstream process, Downstream process - infrastructure, and Total distributed the numbers are expressed per 1 kWh electricity delivered to a customer connected to the 70/130 kV nework (distribution loss, 3 % of generated electricity). Distribution losses vary depending on what voltage level the customer is connected to. These are described in chapter 2.4 Electricity Transmission and Distribution.
