Service Providers Directory — Engineering Firms by State

We connect you with experienced engineering firms and expert assessors that specialise in your region. Choose your federal state (Bundesland) — the enquiry is free and non-binding.

How it works: choose your state → describe your enquiry → we refer you to a suitable engineering firm in your region. No referral fee, no risk.

How the Referral Process Works

After your enquiry, we check which engineering firm in our network fits your project, your region and the required service. Regional proximity matters more for on-site expert reports (e.g. acoustic measurement, ground investigation) than for procedures handled mostly at a desk (e.g. BImSchG application coordination). Within a few working days you receive a reply with one or two matching contacts — further coordination, quoting and engagement happen directly between you and the firm; we do not become a party to that contract.

Partner firms are selected on traceable criteria: relevant reference projects in the relevant turbine class, capacity for the requested timeframe, and — for expert reports — the professional accreditation required for that specific service (e.g. an acoustic assessor accredited under the relevant standards). We do not check the creditworthiness or legal form of partner firms and accept no liability for the service delivered — that remains a matter of the direct contractual relationship between client and firm.

For City-States and Land-Scarce Federal States

Hamburg, Bremen and Berlin have little relevant land available for wind turbines — demand there shifts noticeably toward ground-mounted PV on conversion and commercial sites, grid-connection planning, and battery-storage projects. Providers active in these regions should position accordingly toward those service types rather than classic wind-turbine expert reports to stay visible in our referral matching.

What Helps Us Match You Faster

The more specific your enquiry, the faster the referral: project type (repowering or new build, wind or solar), rough turbine count or capacity class, state and site region, and your desired timeframe let us suggest a matching firm directly instead of going back and forth on basic details first. If you already have a preferred timeline or budget range, mentioning it upfront also helps us pre-filter for firms with matching availability.

Note: We are not an engineering firm but an independent specialist portal. Contracts are formed directly between you and the referred firm. The referral does not incur any costs for you. See Privacy (DE) and Imprint (DE).
