Offshore Wind
Tetra Tech provides industry-leading, science-based permitting, siting, and environmental services and compliance-focused solutions for construction, operations, and maintenance to support the entire life cycle of the offshore wind supply chain.
Our team of planners, project managers, scientists, engineers, and regulatory specialists has supported the development and permitting of offshore wind projects ranging from 12 to 2,640 megawatts. Tetra Tech is the lead environmental consultant for the only two currently operational offshore wind projects in the United States and continues to leverage our deep bench of marine-based and onshore generation and transmission services to successfully navigate the offshore wind regulatory process.
Tetra Tech supports offshore wind developers with initial project planning, including due diligence, fatal flaw analysis, and stakeholder engagement. We lead all local, state, and federal permitting and licensing efforts and provide construction and operations support, including comprehensive compliance services driven by data collection, evaluation, and management. Our onshore permitting and siting services include field surveys, evaluation of points of interconnection, routing, and alternatives assessments. Tetra Tech’s submarine cable services experts focus on cable route constraints analysis and engineering, marine survey planning, and in-depth studies.
