Terranets bw

What Terranets bw does

Terranets bw GmbH is a regulated German gas transmission system operator (TSO) headquartered in Stuttgart, operating as a wholly-owned subsidiary of EnBW Energie Baden-Württemberg AG. The company operates an extensive high-pressure gas pipeline network spanning from Lower Saxony in northern Germany to Lake Constance (Bodensee) in the south, complemented by a high-performance fibre optic telecommunications network across Baden-Württemberg. Its primary customers include downstream regional gas distribution network operators, gas shippers and traders, industrial connection customers, and telecommunications operators, all served through regulated tariff arrangements under German energy law and bilateral B2B contracts.

The company generates revenue primarily through regulated gas transmission tariffs charged to downstream grid operators, shippers, and connection customers, supplemented by fibre optic telecommunications infrastructure services and a portfolio of technical services for high-pressure pipeline facilities (planning, construction, maintenance, testing, inspection, and system rental). Capacity booking and management is facilitated through the ConnectCapacity digital customer portal, while technical and pipeline route information is provided via the BIL Online portal. Pricing for gas transmission is set within the German regulatory framework and is not publicly disclosed; technical services are quoted per customer requirement. The company's go-to-market is enterprise field sales directed at regulated counterparties rather than competitive market acquisition.

Terranets bw is actively repositioning its infrastructure for the energy transition, with the Süddeutsche Erdgasleitung (SEL) serving as the central hydrogen supply artery for Baden-Württemberg. The company is a core partner in Germany's national hydrogen core network, which was approved by the Bundesnetzagentur on October 22, 2024 and targets approximately 9,040 km of hydrogen infrastructure by 2032 at an estimated cost of EUR 18.9 billion. Strategic partnerships include the Flow project with GASCADE and ONTRAS (with 400 km already commissioned) for a North-South hydrogen corridor, and the RHYn Interco cross-border hydrogen corridor with NaTran and bnNETZE for France-Germany connectivity from 2030. The company also operates the "Initiative Hydrogen for Baden-Württemberg" stakeholder engagement program.
