What TEN Thuringian Energy Networks does

TEN Thuringian Energy Networks (legal name: TEN Thüringer Energienetze GmbH & Co. KG) is the regulated distribution system operator (Verteilnetzbetreiber) for electricity and natural gas across the German state of Thuringia, headquartered in Erfurt. The company operates low-, medium-, and high-voltage electricity networks and gas distribution networks, and acts as the default meter operator (grundzuständiger Messstellenbetreiber) responsible for installing, operating, and maintaining conventional meters, modern metering devices (mME), and intelligent measurement systems (iMSys/Smart-Meter-Gateways) under the Messstellenbetriebsgesetz. Customers include electricity and gas suppliers (Stromlieferanten), households and businesses (Netzkunden), renewable energy producers (EEG/KWKG Einspeiser across solar, wind, CHP, hydro, and storage), heat pump and EV wallbox owners using §14a EnWG controllable load rules, and registered installers (Installateurverzeichnis) across the Thuringian territory.

TEN's product portfolio is organized around regulated grid infrastructure services: network connections across voltage levels, metering operations (operationally executed by its core subsidiary TMZ Thüringer Mess- und Zähhlerwesen Service GmbH), feed-in management (Einspeisemanagement), grid security management (redispatch, curtailment, compensation), EV charging infrastructure connections, controllable consumption device management, hydrogen infrastructure planning, and tenders for grid loss coverage. The company exposes four customer-facing portals — Netzkundenportal (connection applications), Planauskunftsportal (cable routing), Web.check (load profile analytics), and EnergiePortal (smart-meter data). It also runs an Installateurverzeichnis gating installer access to the network. TEN is a wholly or majority-owned subsidiary (Netztochter) of TEAG Thüringer Energie AG and operates within the broader Thüga group ecosystem.

Revenue is generated through regulated network charges (Netzentgelte approved by Bundesnetzagentur and the Thuringian regulatory chamber), regulated metering charges under MsbG price caps, one-time grid connection fees (Netzanschlusskosten/Baukostenzuschuss), and grid services (Netzdienstleistungen) including planning, construction, maintenance, and rental of transformers, construction power, and emergency generators. The company holds ISO 14001, ISO 50001, TSM, DVGW, and VDE certifications, complies with the Lieferkettensorgfaltspflichtengesetz (LkSG), and maintains 24/7 outage hotlines for both electricity and gas disruptions.

Network charges are a regulated revenue stream approved by the regulatory authority (Bundesnetzagentur or Thuringian regulatory chamber).
2. Metering Services (Messstellenbetrieb): As default meter operator, TEN earns revenue from installing, operating, monitoring, maintaining, and replacing meter equipment. Revenue comes from与现代 measuring devices (mME) and intelligent metering systems (iMSys). Pricing is regulated under the Messstellenbetriebsgesetz (Metering Operations Act) with price caps set by Bundesnetzagentur.
3. Grid Connection Services: One-time fees for new grid connections including network connection costs (Netzanschlusskosten) and grid connection charges (Baukostenzuschuss/BKZ). Ongoing fees for modifications to existing connections.
4. Grid Services (Netzdienstleistungen): TEN offers services including planning, construction and operation of low voltage, medium voltage, and gas pipelines; maintenance of networks; transformer station and gas pressure regulation station services; rental of transformers, construction power stations, and emergency power generators.
