GASAG Berliner Gaswerke AG

What GASAG Berliner Gaswerke AG does

GASAG Berliner Gaswerke AG is a Berlin-headquartered regional energy utility founded in 1847, serving approximately 700,000 residential and business customers across Berlin and Brandenburg with electricity, natural gas, heat, and increasingly decarbonized energy services. Electricity is offered as 100% renewable power certified under the RenewablePLUS and Verified Carbon Standard labels, with product variants including a monthly cancellable Direkt tariff, a 24-month Spreestrom tariff, a heat-pump electricity tariff, and a Dynamischer Stromtarif that exposes customers to hourly exchange pricing. Beyond commodity supply, GASAG sells and consults on solar PV systems, heat pumps (with a bundled PV-plus-heat-pump Komplettpaket), EV wallboxes, and adjacent services such as building thermography and Sanierungsfahrpläne, positioning the firm as a one-stop decarbonization partner for Berlin-area homes and businesses.

The underlying technology stack is conventional utility infrastructure combined with a maturing digital layer. Distribution runs through NBB Netzgesellschaft Berlin-Brandenburg, while customer-facing operations use the MEINE GASAG online portal and mobile app, social-login identity via Microsoft Azure AD B2C (with Google, Apple, and Facebook options), WhatsApp customer service via Superchat's SuperX GmbH platform, and a Trustpilot widget for social proof. Marketing and analytics leverage Facebook Pixel, LinkedIn Insight Tag, and Google AdServices. Back-office procurement is being modernized through Mercanis, an AI-powered supplier-management and tendering platform, alongside IntegrityNext for supplier ESG screening, with the company reporting over 40% process cost reduction and a 12x ROI from this rollout.

Revenue is generated primarily through recurring consumption-based electricity and gas supply contracts across five customer segments — Privatkunden, Mittelstand, Gewerbe, Industrie, and Wohnungswirtschaft — supplemented by project-based solar and heat-pump hardware sales. Annual procurement volume runs €250–280M (disclosed by Head of Procurement Uwe Krepelin), of which roughly half is construction services. Distribution is multi-channel: direct online (gasag.de tariff calculator, MEINE GASAG self-serve), inside sales via the 030 7072 0000-0 hotline, dedicated B2B sales for commercial and housing-industry clients, and a physical Kundenzentrum. The company is led by a three-member Vorstand chaired by Georg Friedrichs, with Eric Stab as Aufsichtsratsvorsitzender, and operates as the parent of the GASAG Group with wholly-owned subsidiaries including NBB, BAS Kundenservice, GASAG Solution Plus, and EMB Energie Brandenburg.

Comparable to GASAG as a large German Stadtwerke with both regulated network operations and retail supply, plus decarbonization strategy.
• EWE AG: Oldenburg-based multi-utility serving northwestern Germany with gas distribution, electricity, telecommunications, and energy services. Comparable to GASAG as a regional utility with both regulated gas network operations (EWE Netz) and broad retail supply across gas, power, and emerging heat/EMobility offerings.

Broad incumbents

• EnBW Energie Baden-Württemberg AG: One of Germany's four largest integrated utilities with regulated networks, generation, and retail across electricity and gas. Comparable to GASAG at a much larger scale; competes in retail and increasingly in municipal heat-pump and EV infrastructure rollouts.
• E.ON SE: Germany's largest network operator and multi-utility with regulated electricity and gas distribution networks across multiple regions. Comparable to GASAG's network operations via NBB but at national scale; also a major competitor in B2C/B2B energy supply and heat-pump sales.
• Vattenfall GmbH: Swedish state-owned utility with significant German operations in Berlin including heat networks, electricity retail, and large-scale renewables. Directly competes with GASAG in the Berlin market for residential and commercial energy supply, district heating, and municipal customers.

Regional players

Comparable to GASAG as a regional multi-product utility with renewable offerings, though operating in a different geography (southern Germany).
• Stadtwerke Leipzig GmbH: Leipzig's municipal multi-utility supplying electricity, natural gas, district heating, and water with renewable energy investments. Comparable to GASAG as a similarly sized German Stadtwerke with combined regulated network and retail activities, though operating in Saxony rather than Berlin.
