Investment in new electric transmission lines has been lagging since the restructuring of the electric industry. New England has done better than many parts of the country in building new electric lines needed for the reliable operation of the grid, but it is broadly recognized that more investment is needed in order to make up for years of underinvestment. Meanwhile, states continue to pass legislation calling for greater use of electricity from renewable energy sources.

The intent of this section is to bring a broader perspective on the need for new transmission infrastructure investment and particularly the need for transmission that provides grid access for renewable energy resources, which by their nature are typically located in places away from where the largest demand for electricity is located. The Federal Energy Regulatory Commission has referred to wind, biomass, geothermal and other renewable resources as “locational constrained resources” and has supported public policy that removes some of the financial uncertainty of constructing new transmission lines to these resource areas.
