Meet us


TenneT Holding B.V. was established to segregate our statutory tasks from our non-regulated activities. It is wholly owned by the Dutch Ministry of Finance.

Regulated activities

Virtually all of TenneT's activities are regulated. These activities are governed by relevant legislative and regulatory provisions in the Netherlands and Germany. Regulatory authorities, Autoriteit Consument & Markt (ACM) and Bundesnetzagentur (BNetzA) oversee TenneT's compliance with these provisions. TenneT's regulated activities are managed on country level by two operating segments TSO Netherlands and TSO Germany.

Non-regulated activities

TenneT is involved in certain limited non-regulated activities, which help to ensure the energy market operates smoothly and efficiently, or are ancillary to it. As such, TenneT holds a 50% interest in BritNed, a merchant cable operator that manages the electricity interconnector between the Netherlands and Great Britain. TenneT also owns 100% of NOVEC and Relined; these companies manage infrastructure to send and receive broadcasting and telecom signals. Furthermore, TenneT (indirectly) holds a 17% share in EPEX Spot SE (EPEX), the NWE (including Great Britain) electricity exchange.
