Legal risks of wind power generation projects
As with any development, wind energy projects can become the subject of litigation in state and federal courts. In addition, regulatory litigation before state utilities commissions and the Federal Energy Regulatory Commission (“FERC”) can have profound effects on the viability of. These locally imposed dimensional and performance standards, particularly restrictive setback requirements, frequently become the main barrier that can delay a project's development. Conventional powerplants – coal, gas etc – are generally procured using a lump-sum. To sufficiently protect your investment, you must identify the unique sets of risks you will face during every phase of the investment: contracting, construction and ongoing operations. -
