What Mainfranken Netze does

Mainfranken Netze GmbH (MFN) is a regulated regional multi-utility network operator (Netzbetreiber) headquartered in Würzburg, Germany, and a 100%-owned subsidiary of Stadtwerke Würzburg AG within the WVV-Konzern. Established in 2007 as part of the statutory unbundling of energy networks under the German Energy Industry Act (EnWG), MFN operates and maintains four core utility networks serving the Würzburg and Mainfranken region across an 80.5 km² service area: approximately 2,800 km of electricity lines (with ~4,500 connected generation plants), 700 km of gas pipelines, 516 km of water network, and 60 km of district heating — plus the largest fiber optic network in Würzburg. The company also serves as the basic metering operator (grundzuständiger Messstellenbetreiber), deploying modern metering devices (mME) and intelligent metering systems (iMSys) with BSI-certified Smart Meter Gateways. MFN holds AGFW TSM, DVGW TSM, and VDE TSM technical safety management certifications and operates under supervision of the Bundesnetzagentur (electricity) and Regierung von Unterfranken (gas).

The company's core customer-facing product is the MFN Netzportal, a web-based platform enabling network customers (Netzkunden), feed-in operators (Einspeiser), and certified installers (Installateure) to submit applications for network connections, meter services, and generation plant registrations with automated status tracking. Supporting operational systems include Redispatch 2.0 grid congestion management (coordinating EEG, CHP, storage, and large consumers above 100 kW), grid compatibility verification (Netzverträglichkeitsprüfung) for feed-in installations, and digital network documentation. The company publishes regulated price sheets (Preisblätter) covering network usage fees, meter operation, connection costs, and concession charges for 2024, 2025, and 2026.

Revenue is generated exclusively through regulated channels: recurring network usage fees (Netzentgelte) for electricity and gas distribution, regulated meter operation fees, one-time network connection fees (Hausanschlüsse) with capital cost contributions (Baukostenzuschuss), and ancillary regulated charges (blocking/reconnection, data provision, individual network fees). Customer segments include residential households, commercial/industrial enterprises, renewable generation operators (PV, wind, CHP, biogas), installation companies, and energy suppliers/traders across 13 concession municipalities. Strategic initiatives under Würzburg's 2040 climate neutrality goal include hydrogen grid transformation planning, steam-to-hot-water conversion of the district heating network, smart meter rollout through 2032, and Solarspitzen-Gesetz/§14a EnWG compliance services for new electrification loads.
