    HDR provides a complete array of lead licensing and relicensing consultant services for strategic planning, multi-party negotiations, environmental and engineering studies, operations modeling, and document and application preparation....

  • HDR is the leading provider of licensing and relicensing services to clients in the hydropower industry, having involvement with over 100 developments in 20 states. This experience translates to a skillful understanding of the complex and rapidly changing regulatory climate. We have extensive experience with all of the FERC licensing processes:

    • Integrated (ILP)
    • Traditional (TLP)
    • Alternative (ALP)

    Executing a cost-efficient licensing process that results in a predictable and desired outcome requires a thorough understanding of the regulatory process, supported by regulatory specialists, environmental scientists, and engineers who have extensive experience working within the hydroelectric industry. HDR provides clients with an expert array of lead licensing and relicensing consultant services for strategic planning, multi-party negotiations, environmental and engineering studies, operations modeling, and document and application preparation. Our services also extend to post-licensing compliance support, detailed engineering and design, procurement, construction management services, and ongoing operations support.

    Through our wealth of experience, we understand the challenges of the industry and are better able to negotiate the regulatory process. By employing cost-effective strategies founded on process efficiency and effective communication, and offering the full range of hydroelectric regulatory, environmental, and engineering expertise, we offer clients the singular lead consulting resource that can successfully move projects through the entire licensing process on schedule and within budget.
