A power grid is something very special. We are responsible for the secure electricity supply of about 18 million people, and are aware of this extraordinary responsibility. That is why we like to perform our work in a transparent way: offline in front of the many visitors to our head office, and online by publishing important data about our grid, even including information that we are not legally obliged to disclose. Transparency is part of our corporate culture. That is why we have, for example, been publishing the hourly load on our lines for the last five years; and we are the only German transmission system operator to do so. We regularly publish further data underregelleistung.net.
