Preliminary projections by ISO New England load forecasters indicate flat to slight growth in energy consumption in New England for the ten-year period from 2012 to 2021. However, peak demand is expected to grow at a slightly faster pace over the same period.
Preliminary energy demand forecasts project a compound annual growth rate of 0.9% in energy consumption in New England over the next ten years, increasing from the anticipated 138,195 gigawatt-hours (GWh) in 2012 to about 150,375 GWh in 2021. Further analysis that reflects the demand-reducing effects of passive demand resources participating in the Forward Capacity Market (FCM) and incorporates preliminary estimates of the long-term effects of state energy-efficiency programs indicates that New England energy consumption will remain essentially flat. That analysis shows a slight decline from a projected 132,705 GWH in 2012 to approximately 132,440 GWh in 2021.
Preliminary peak demand forecasts project growth of approximately 1.5%, from a forecasted peak of approximately 27,440 megawatts in 2012 to approximately 31,255 megawatt-hours (MWh) in 2021. Further analysis that reflects the effect of passive demand resources participating in the FCM and incorporates preliminary estimates of the long-term effects of state energy-efficiency programs indicates that New England peak demand will grow by a compound annual growth rate of approximately 0.7%, increasing from approximately 26,480 MWh in 2012 to approximately 28,145 MWh in 2021.
ISO New England expects to finalize and present its 2012 long-term demand forecast to the Planning Advisory Committee later this spring.
