In 2009, under the Premiership of Dalton McGuinty, the Ontario legislature passed the Ontario Green Energy Act (GEA), an Act that aimed to increase Ontarios use of renewable energy such as wind power, solar power, biofuels, and small-scale hydropower. The centerpiece of the Act is a schedule of subsidized electricity purchase contracts called Feed-in-Tariffs that provide long-term guarantees of above-market rates for power generated by those renewables.
