Potential demand management savings worth $3 billion/yr in USA

According to new reference in the Wikipedia article on Demand Response ” study carried out in 2007 by The Brattle Group  for the United States showed that even a 5 percent drop in peak demand would yield substantial savings in generation, transmission, and distribution costs – enough to eliminate the need for installing and running some 625 infrequently used peaking power plants and associated power delivery infrastructure. This would yield an annual savings of $3 billion which translates into a present value of $35 billion over the next two decades.” No doubt similar savings are achievable by interlinking and strengthening the US grid interconnections as happened in the UK when its National Grid was constructed, and as would happen if European grids were interlinked, due to the retirement of duplicated and inneficient peaking and back up plant.
