Rzvn Wehr

What Rzvn Wehr does

RZVN Wehr GmbH (legal name: Rechenzentrum für Versorgungsnetze Wehr GmbH) is a privately held German engineering consultancy, founded in 1961 and headquartered in Düsseldorf with a second office in Berlin. The firm specializes in the technical and economic planning, calculation, and optimization of energy and water supply networks — gas, water, district heating, and electricity distribution — serving municipal utilities, regional network operators, and energy suppliers across the DACH region (Germany, Austria, Switzerland).

The firm's core offerings are three proprietary software products combined with project-based consulting services. ROKA³ performs grid calculation for gas, water, and heat networks and has been released in a new generation in 2026. RIKA is a risk-based asset management and renewal-planning tool, applied to over 20,000 km of pipe networks across utilities in Germany and Switzerland (including a DVGW research project covering 20,600 km across 10 utilities). CityCockpit is a cross-sectoral simulation platform that models building-level, hour-precise electricity and heat demand, cross-sectoral P&L, CO2 emissions, and 50-year system transformation pathways for cities. Consulting services include network analysis, target network planning (advertised 10–30% infrastructure savings potential), risk-based renewal planning, e-mobility impact studies, crisis management for gas infrastructure, and municipal heat planning under the Wärmeplanungsgesetz. The firm references more than 400 customers in the German-speaking region.

Revenue is generated through professional services engagements and software licensing of ROKA³, RIKA, and CityCockpit; pricing is quote-based and not publicly disclosed. Go-to-market is direct B2B sales to enterprise utilities, supplemented by LinkedIn, a biannual newsletter (Netzblicke), industry events, and online ROKA³ video courses. The company has approximately 29–30 employees across the two German offices and is led by authorized managing director Jessica Rücken. No external funding, M&A activity, or public-market listing has been disclosed.

Core offering

RZVN Wehr GmbH is an engineering consultancy that delivers technical and economic consulting for energy and water distribution networks (gas, water, district heating, electricity) to municipal utilities and network operators in the DACH region. The company develops and licenses proprietary software — ROKA³ for pipe network calculation, RIKA for risk-based renewal planning, and CityCockpit for cross-sectoral energy system simulation — and wraps consulting services (network analysis, target network planning, e-mobility impact assessment, crisis management, municipal heat planning) around these tools.

Product overview

RZVN Wehr offers a portfolio of proprietary grid calculation and energy infrastructure planning software. The core products are ROKA³ (grid calculation software for gas, water, and heat networks), RIKA (risk-based renewal planning tool), and CityCockpit (cross-sectoral energy simulation platform). The three software modules work together: CityCockpit provides strategic energy infrastructure planning using building-level and hourly simulation data; ROKA handles the operational grid calculations across utilities; and RIKA supports risk-based renewal planning. The company also provides professional consulting services in water, gas, district heating, electricity, and heat planning.
