The chart shows the electricity generation already achieved from cogeneration plants and wind power as well as a possible timetable for further expansion. In addition to self-supply, supplementary electricity procurement and power transport between the properties is also required. The aim is to minimise external electricity procurement as quickly as possible by installing the systems at an early stage. The company is also looking into utilising other electricity-generating plants, renewable energy sources and energy storage systems in order to increase the share of electricity generated in-house. Future electricity procurement contracts will therefore be expanded to include balancing group management.
