Hochfrequenz

What Hochfrequenz does

Hochfrequenz Unternehmensberatung GmbH is a German management and IT consulting firm founded in 2009 by Andreas Hoelzer and headquartered in Grünwald near Munich. The firm specializes exclusively in the German-speaking energy sector — serving energy utilities (Energieversorgungsunternehmen), grid operators (Netzbetreiber), metering system operators (Messstellenbetreiber), and energy service providers — with a particular focus on SAP IS-U and S/4HANA Utilities implementations, regulatory compliance (GPKE, MaBiS, EnWG, MsbG), and digital transformation. The company employs more than 140 people distributed across offices in Grünwald, Berlin, Bremen, Leipzig, Köln, and Stuttgart, enabling on-site consulting delivery across Germany. Co-managing directors are Andreas Hoelzer (founder, 20+ years of energy consulting, SAP IS-U implementation focus), Thorsten Förg (co-MD since 2010, program/project management and IT strategy), and Joscha Metze (joined 2025, software architecture and German market communication expertise). The firm has been an SAP Services Partner since 2012 and has held SAP Recognized Expertise for Utilities in Germany since 2015.

The company combines process consulting, IT consulting, and software development under one roof. Its proprietary HF Apps suite — comprising AHB-Tabellen, Bedingungsbaum, EBD-Diagramme, and Digitaler Fristenkalender — bundles EDI@Energy application handbooks, BDEW decision-tree diagrams, and market communication deadlines into web-based tools targeted at energy market professionals. Supporting these tools are the 'Hochfrequenz erklärt' YouTube video series and the 'Deep Dive Fakten' knowledge database, which function as content-marketing assets for top-of-funnel demand generation. Named customers include E.ON, EnBW, Mainova, RheinEnergie, SWM (Stadtwerke München), Stadtwerke Düsseldorf, Stadtwerke Saarbrücken, KELAG, Regionetz, STAWAG, LynchTech, and itestra. Documented engagements include a 21-month SAP S/4HANA Utilities transformation at Stadtwerke Saarbrücken Netz AG completed within planned time and budget, and DevOps support for Mainova's SAP EDM environment including migration to the Thüga billing platform (TAP).

Revenue is generated through project-based professional services engagements — primarily multi-year transformation and SAP implementation projects sold via direct enterprise field sales. Pricing is contract-specific and not publicly disclosed. Strategic technology partnerships (SAP, cerebricks, Natuvion, LYNQTECH) and an active role in industry standardization (DSAG energy working group, BO4E initiative) extend the firm's delivery capacity and reinforce its positioning as a specialist transformation partner. In January 2026, EMERAM Capital Partners took a growth-investment stake to support further expansion of consulting competencies and digital solutions, with management remaining unchanged. Quality is governed by ISO 9001:2015 certification (TÜV SÜD, since June 2012), and the firm has been named one of Germany's best management consultancies by brandeins/Statista for nine consecutive years and a kununu Top Company for five consecutive years.
