WASHINGTON – Today, the Institute for Energy Research will send letters to public utility commissions in all 50 states urging them to protect American families from the imprudent costs of the EPA’s so-called “Clean Power Plan.” The letter highlights the findings of IER’s new report on electricity costs. Using data from EIA and FERC, the report finds that existing sources of electricity generation are more affordable than new sources. Electricity from even the least expensive new sources is nearly double the cost of that from existing coal power.
