The Challenge

Energy demands are increasing – and so is the need for accurate information and analysis on potentially available resources, optimal siting, and environmental impacts and benefits. The success of renewable energy development depends on a careful preliminary assessment, planning, permitting, site and facilities development, and asset maintenance, with consideration of the multiple interests of engineering and energy firms, landowners, environmental groups, and the public.

Innovative Solutions

Sewall has been at the forefront of energy development and offers customized solutions to meet the needs of our private- and public-sector clients for wind and solar energy generation projects.
