Sweden is a large country in terms of area with a relatively cold climate. In this area there are almost 3400 churches spread around the country where about 1700 of them are electrically heated, which makes battery storages suitable. The churches are heated depending on demand and opening hours, during the rest of the time, the temperature is kept low. The churches, like most buildings in Sweden, get electricity from the 50 Hz grid. Due to the intermittent heating, power spikes occur in the grid which are both ineffective and expensive for the owners of the buildings. The purpose of this work is to make the church’s heating more efficient with the help of a well-dimensioned battery storage that can assist during heating. This would result in a more stable heating process and also save a lot of money. During the project a dimensioning tool for battery storage was developed and when applied in a case study revealed that the battery storage would become profitable after 12-18 years, this is longer compared to the estimated battery lifetime which in this report was set to be around 10 years.
