    Variable power sources (e.g. wind, photovoltaics) increase the value of flexibility in the power system. This paper investigates the benefits of combining electric heat boilers, heat pumps, CHP plants and heat storages in a district heating network when the share of variable power increases considerably. The results are based on scenarios made with a generation planning model Balmorel [1]. Balmorel optimises investments and operation of heat and power plants, including heat storages. It uses hourly resolution and enforces temporal continuity in the use of the heat storages. Scenarios with high amount of wind power were investigated and the paper describes how the increase in variability changes the profitability and operation of different district heating options in more detail than was described in the article by Kiviluoma and Meibom [2]. Results show that district heating systems could offer significant and cost-effective flexibility to facilitate the integration of variable power. Furthermore, the combination of different technologies offers the largest advantage. The results imply that, if the share of variable power becomes large, heat storages should become an important part of district heating networks.
