Regional power grid administration ISO New England predicts only modest growth in electricity consumption over the next 10 years.
Through 2021, ISO forecasts an annual 0.9 percent growth rate in electricity consumption in New England, peaking at 150,375 gigawatt hours in 2021.
Demand of electricity has been an economic indicator has greater electricity use equates to more business hookups and activity, particularly with large users such as manufacturers. However, other impacts such as fair weather and energy efficiency programs impact consumption.
Electricity demand in 2011 declined 1.2 percent, mostly because the weather in 2011 was more temperate than 2010.
Because each of the six New England states have energy efficiency programs to reduce consumption in their states, ISO says the 10-year forecast might change slightly, with even less demand anticipated for electricity.
