Independent Engineering Reports

An Independent Engineer (IE), also known as a Lender’s Engineer or Owner’s Engineer, provides non-biased 3rd party reports to help identify and mitigate the possible risks of proposed renewable energy projects from pre-finance due diligence, to construction, and operation.
