James W. Sewall Company takes wind energy business to national summit

The geospatial, engineering and natural resource consulting firm James W. Sewall Company will promote Offshore Wind Energy GIS (OWEGIS) technology, aerial mapping, siting, and engineering services at the AWEA Offshore WINDPOWER Conference & Exhibition on October 11-13, in booth 331 at the Baltimore Convention Center in Maryland.

"Sewall has assisted in the development of 10 commercial-scale wind projects representing 300 wind turbines and over 600 mw of potential energy production," explains Director of Renewable Energy Services Patrick Graham. "Based on our experience in providing surveying, civil engineering, aerial mapping, GIS database and software development to wind developers onshore, we plan to be a serious player in the expanding US offshore wind market."

Sewall, working in partnership with the University of Maine through the Offshore Wind Development Initiative, has already brought the power of geospatial technology to the study of ocean renewable energy and wind power production potential in the Gulf of Maine (GoM). This technology--the Offshore Wind Energy GIS (OWEGIS)--is an innovative ecospatial information system that is being used to identify areas for offshore wind farm development and to rank their potential according to environmental, cultural, economic, and commercial impacts. Sewall, as a member of the DeepCwind Consortium, is currently applying OWEGIS to assist with the permitting of the first floating offshore wind project in North America. Sewall is also working with a consortium of organizations to apply the OWEGIS data architecture to exploring the siting of wind power projects in the Great Lakes.

Sewall has a long history of supporting traditional energy projects throughout the US. Most recently Sewall was commissioned by National Grid, an international investor-owned gas and electric utility that delivers electricity to 3.3 million customers in Massachusetts, New Hampshire, New York, and Rhode Island. The deliverables--aerial imagery of the entire route and mapping and orthos for five out of six substations along the route--were essential to National Grid's planning and engineering of future electric transmission projects in the region.
