What AEK Energie AG does
AEK AG is an integrated building technology services provider headquartered in Solothurn, Switzerland, operating as a subsidiary of BKW Building Solutions AG within the BKW Group (BKW Energie AG, SIX Swiss Exchange: BKW). The company was originally founded in 1955 as Ziegler AG and rebranded to AEK AG in 2019 following the 2007 merger with AEK Elektro AG. With approximately 270 employees distributed across 18 regional branch offices in the Solothurn, Aargau, and Oberaargau regions, AEK delivers a multi-trade service portfolio spanning electrical engineering, ICT, HVAC (Heizung, Lüftung, Klima, Sanitär), solar energy, e-mobility charging infrastructure, building automation, and plumbing. The company also offers specialized solutions including MSRL (Mess-, Steuer-, Regel- und Leittechnik), HLKSE installations, NurseCall systems, and ZEV (Zusammenschluss zum Eigenverbrauch) solar energy communities in partnership with engytec AG, alongside managed cybersecurity services (Cyber Defense Center as a Service, Managed Antivirus EDR with AI-based ransomware protection).
AEK's business model is project- and service-contract based, generating revenue across installation, maintenance, and managed service engagements. Pricing is structured per project or per service contract, with 24/7 support offerings reinforcing recurring relationships. The customer base is structurally diversified across private individuals, SMEs, large enterprises, and public sector clients in Swiss German-speaking regions. Go-to-market is branch-led: customers access AEK through 18 local offices, each with its own branch management, which supports proximity-driven sales and rapid on-site response. The company's positioning within BKW Building Solutions AG provides group-level back-office, procurement, and cross-sell capabilities that complement its regional operating model.
The company's strategic posture is oriented toward extending its integrated building technology platform into higher-growth adjacencies: managed cybersecurity services for enterprise and municipal clients, renewable energy community (ZEV) solar offerings via the engytec partnership, and e-mobility charging infrastructure deployment. While the core trades-based services drive the majority of revenue, these newer digital and energy-transition verticals represent the principal growth levers and inform AEK's long-term product evolution within the BKW Group ecosystem.
