Updating the security of supply level in the finnish electricity distribution systems — A real life case of changing the legislation from the viewpoint of the ministry

This paper describes a law drafting process for amending the Electricity Market Act that was undertaken in the Finnish Ministry of Employment and the Economy during the year 2012. The goal of the process was to upgrade the performance standards for the security of supply in the Finnish electricity distribution systems. The outcome of this paper is two-fold: first we describe a real life case of drafting the legislation concerning the electricity network security of supply levels in Finland and secondly we shed light on the historical reasons and different limitations, which affected the final bill. We also present the main content of the bill in respect of the new network security of supply levels and other improvements in the Finnish distribution system operator´s prepardness against the main climatic threats and in their performance during emergency situations.
