State-scale evaluation of renewable electricity policy: The role of renewable electricity credits and carbon taxes

►We examine state-scale impacts of a renewable electricity standard and a carbon tax. ►Georgia has low electricity prices and bioenergy is the main renewable option. ►A carbon tax of $50/tCO2 does not significantly increase renewable generation. ►Renewable electricity credits divert renewable investment to other states. ►Keeping renewable electricity generation in-state increases electricity costs by 1%.
