Abstract
The future of climate and sustainable energy are interrelated. Speaking of one without mentioning the other is quite difficult. The increasing number of natural disasters pose a great threat to the electric power supply security in any part of the world. Sweden has been one of the countries that have suffered from unacceptably long blackouts. The tremendous outcomes of the power interruptions have made the field of the economic worth of electric power reliability a popular area of interest among researchers. Nature has been the number one enemy against the supply security of the electricity. This paper introduces a recent and thorough electric power reliability analysis of Sweden and focuses on the country’s struggle against climate change-related natural disasters via updating the country’s electric power policy to improve its service quality. The paper highlights the Gudrun storm of 2005 as a case study to demonstrate the severe impacts of extreme weather events on the energy systems. The economic damage of the storm on the electric power service calculated to be around 3 billion euros.

The protection of the customers’ right is of vital concern. These facts make Sweden a proper place to study the impacts of natural disasters on electric power reliability
Summary
If a single power outage event extends a predefined duration, the DSO is to pay back to the customer a certain percentage of the customer’s annual electricity delivery fee as a penalty. After the Gudrun storm, in October 2005, the Swedish government updated the electricity law and made the compensation scheme of 2001 compulsory for the DSOs [18]. Another update came during 2014 [19]. The electricity law states that, under certain limited conditions, the electricity consumer is not entitled to earn compensation for power interruption, despite a service break.
