Residential electricity prices are expected to spike by more than 10 percent beginning in 2015, with consumers paying between $150 and $330 a year more than this year, as coal plants, the least expensive producers of electricity, continue to close.
Analysts who follow electricity pricing will have a firmer idea Friday of how much consumers' bills will go up. It's the day the agency that manages the electric grid, known as the PJM Interconnection, will announce the results of an annual auction that reserves power three years in advance.
