Many grid operators face the same challenge: The demands on the medium-voltage grid are constantly increasing—yet at the same time, the existing infrastructure needs to continue to be used cost-effectively.
How can we successfully digitize local network stations?
By 2028, Gemeindewerke Grefrath will digitize about half of its local network stations using a retrofit concept, thereby increasing network transparency, supply reliability, and operational efficiency with minimal renovation effort.
