Reservoir lakes are basically giant batteries that are able to store and deliver electric energy. The Swiss Federal Office of Energy (SFOE) regularly publishes weekly data concerning the current fill level of Swiss reservoir lakes in GWh and the current fraction of the maximum possible fill level. Unfortunately, the data from the SFOE is only available as PDF. This repository provides the data in csv format (starting from 1997-01-06) which was obtained through a PDF scraping (starting from 2003-01-06) and manual integration (1997-01-06 until 2002-12-30; only partial data available) of the yearly PDF files from the SFOE.
