Onshore Wind

Tetra Tech is a trusted partner for onshore wind development, offering integrated services that span the entire project lifecycle. We are a global leader in the onshore wind energy market, ranked #2 in Wind by Engineering News-Record. Our multidisciplinary teams support developers, investors, and public sector organisations in delivering efficient, bankable, and environmentally responsible wind energy projects across the UK and Europe.

Optimising turbine placement is crucial for maximising energy output, and requires thorough management of terrain, soil conditions, and foundation stability. At the same time, protecting wildlife and natural habitats calls for careful planning. Our technical experts bring together planning, environmental, engineering, construction, and grid capabilities to unlock project value. Through our Leading with Science® approach, we ensure onshore wind schemes are feasible, compliant, and optimised for long-term performance in a complex regulatory landscape.
