“The findings reflect reasonably consistent patterns of price response. At the national level, electricity price elasticity of -0.13 in the short run and -0.42 in the long run have been estimated.”
I first quoted that sentence, from
a 2010 Electric Power Research Institute (EPRI) analysis, in June of last year, in an article related to
a bureaucrat's report. Recently, another bureaucrat of sort, Don Drummond, released
a report that offered some advice that provides a timely excuse to revisit the price elasticity of demand with respect to electricity.

The price elasticity is the figure computed by dividing the change in demand by the change in price - if demand drops 10% when the price rises by 100% (doubles), the measurement is -0.1, which is a frequently noted figure for electricity. The number would vary along the price/demand curve, so all figures can only be guides. The EPRI study noted short term as; "
a time frame of less than three to five years, during which consumers do not have time to make investments in new capital stock." In clear terms a price increase would have a greater impact in the longer term, when consumers have time to make operational decisions based on the new price levels.
