Figure 2 shows CRA’s estimates of difference in the average New England wholesale power prices with and without Cape Wind in service. Over the 25 years covered by the analysis, prices would be an average of $1.22/MWh lower with the project than without. As shown in Figure 3, the effect on wholesale electricity prices is even more pronounced for Southeastern Massachusetts, where the project will be interconnected with the New England grid. The average price reduction for that zone is $1.82/MWh.
Figure 4 shows the expected savings in electricity costs associated with the forecasted reduction in wholesale market prices. The cost savings range between $77 million and $315 million annually, totaling $4.6 billion over the 25 year period.
