Electricity analysis for energy management in neighbourhoods: Case study of a large housing cooperative in Norway

Abstract

Abstract As a basis for energy management in apartment blocks, this paper characterises electricity use in a Norwegian housing cooperative with 1,058 apartments. In 2018, the average specific electricity delivery to apartments and common areas is 56.7 kWh/m2 or 2,301 kWh per resident, in addition to heat delivery from district heating. Average annual electricity use in the apartments is 4,362 kWh and average maximum hourly load is 3.2 kWh/h. The electricity coincidence factor is 0.323. The study suggests a potential for shifting electricity loads in time on a neighbourhood level, where especially EV charging can be utilized as a flexible load.
