A long term large-scale power outage would have a big impact on the society, not least for the elderly and sick people. The Swedish hospitals are well prepared for a power outage. How the municipal healthcare chain would cope with a large-scale power outage is not as well investigated. The purpose with this report is to increase the knowledge about what consequences a power outage would cause at the elderly care homes and how they could prepare for a scenario like that. The goal is to produce a report to ease the planning of emergency power solutions to the elderly care homes. To re-establish the power supply in case of a power outage the most common solution today is a diesel generator. An elderly care home was chosen as a reference to be able to calculate how big efficiency that is needed to supply necessary equipment with enough power. The result showed that the diesel generator need to be able to deliver 640 kVA. A model of the elderly care home was built in the simulation software IDA ICE. A simulation was made to decide how fast the temperature inside the building is sinking in case of an interruption in the district heating system. According to the result the temperature inside the building would be 11 ºC after 48 hours with an outside temperature at almost – 20 ºC. During a day with high temperatures can the inside temperature rise to 29 ºC. A power outage could cause big problems for the elderly care homes if there are no access of diesel generators. A diesel generator which would supply an elderly care home with electricity will consume a big amount of diesel. To facilitate the distribution of diesel in case of an emergency is it important to establish a plan for how much diesel that would be consumed over a day and how to secure the delivery to the most important places. If the power outage occurs during a period with unusually hot or cold weather the vulnerability increases because the elderly people appear to be more sensitive of overheating or hypothermia. To know which buildings that would be prioritized in case of an interruption in the district heating system ore cooling system, would it be an advantage to document the buildings time constants.
