Research Brief: How High Will Electric Prices Go?

Pennsylvania has some of the most inexpensive electricity in this part of the country, but that could change if the state joins the Regional Greenhouse Gas Initiative.

Pennsylvania’s average electricity price is 9.81 cents/kilowatt hour (kWh), about 7% below the U.S. average.

The picture for the Regional Greenhouse Gas Initiative (RGGI) states is much different. Connecticut, one of 11 RGGI states, has the highest electricity prices in the continental U.S., according to the Energy Information Administration.

Looking at the most expensive states in the continental U.S., RGGI states fill the top four slots and eight of the top ten.

The only RGGI state that has lower electricity prices is Virginia – which joined RGGI in 2020 and has been subject to the group’s penalty for producing electricity with fossil fuel for less than a year.

Pennsylvania’s advantage for supplying power to manufacturers and other industrial customers is even greater. The average price paid by Pennsylvania industrial customers is 40% less than the average industrial customer in the RGGI states.

At a time when the Commonwealth is trying to rebuild after facing the pandemic and increased competition, RGGI would strike at one of the state’s genuine economic advantages. RGGI states have seen their electricity prices rise three times faster than Pennsylvania’s.

RGGI requires electricity generators who use fossil fuel to pay a new charge for each ton of carbon they produce. The Wolf administration’s plan is to use the proceeds to invest in renewable energy, energy efficiency improvements, and other projects.

Analysis from the Pennsylvania Department of Environmental Protection predicts that joining RGGI will raise electricity prices in Pennsylvania and cut back electricity sales to other states, which is a major industry in Pennsylvania.[1]

At the same time, the DEP’s economic analysis predicts that the impact of joining RGGI will be so small as to be almost impossible to measure. It estimates that cumulative disposal personal income in the state from 2022-2030 will decrease by .02% compared to not joining RGGI. The analysis also predicts that the state’s gross domestic product will increase by a cumulative .03%.[2]

The DEP’s current analysis also predicts that the state will have 4,300 more jobs in 2030 by joining RGGI (though an earlier analysis predicted 4,300 fewer jobs by 2030.)[3]

And what would Pennsylvania’s joining RGGI do for carbon emissions if all goes according to Gov. Wolf’s plan? It would reduce the country’s greenhouse gas emissions by between 1/1000 and 3/1000 annually.[4]
