Modern society is increasingly dependent on a reliable supply of electricity. Depending on where an electricity outage occurs and who is affected the consequences may range from a mere nuisance to major economic losses or actual threats against the health and safety of citizens. The direct costs of power outages have been assessed in numerous studies, however electricity outages normally also entail indirect costs as well as societal costs. Examples of the latter include impairment of societal functions, impact on health and even loss of life. It is unclear to what extent quality of supply regulations are capturing indirect and societal costs. To address this, a case study is here carried out for electricity customers in a city in Sweden. We investigate to what extent two Swedish quality of supply regulations are reflected in the societal priorities embodied in the Swedish Styrel system. The Styrel system has been in operation since 2011 and is designed to be used during times of power shortage at a national level to prioritize power supply to customers based on their importance for society. Results from the study indicate that electricity customers that are critical for maintaining life and health or vital societal functions seems not to be given due attention in the present regulations.

现代社会越来越依赖可靠的电力供应。取决于停电发生的地方和受影响的人，后果可能范围从仅是令人讨厌的干扰到主要的经济损失或对公民健康和安全的实际威胁。停电的直接成本已在众多研究中进行了评估，但是停电通常还需要间接成本以及社会成本。后者的例子包括社会功能受损，对健康的影响甚至生命丧失。目前尚不清楚供应法规的质量在多大程度上涵盖了间接成本和社会成本。为了解决这个问题，这里针对瑞典某城市的电力用户进行了案例研究。我们调查瑞典Styrel系统所体现的社会优先事项在多大程度上反映了两个瑞典供应质量法规。Styrel系统自2011年起投入运行，旨在在国家电力短缺时使用，以根据客户对社会的重要性来优先为其供电。研究结果表明，对于维持生命和健康或至关重要的社会功能至关重要的电力客户，在本法规中似乎没有得到应有的重视。
