On June 26, 2003, Connecticut Governor John Rowland signed legislation amending the state's Renewable Portfolio Standard (RPS). Connecticut's RPS defines two categories of renewable energy, Class I and Class II, and sets separate requirements for both classes. Under the amended law, Class I includes wind, solar PV, fuel cells, methane gas from landfills, ocean thermal power, wave or tidal power, and some hydropower and biomass. Hydropower facilities that began operation before July 1, 2003 or have a capacity of 5 MW or more are no longer eligible for Class I requirements, which are set at 1 percent in 2004, rising to 7 percent by 2010. Class II includes municipal solid waste facilities, along with certain hydropower and biomass facilities that do not qualify under Class I. Class II requirements are set at 3 percent from 2004 through 2010. Under the previous RPS, renewable requirements applied only to competitive electric suppliers; the new RPS extends the requirements to utilities, which serve the majority of Connecticut's customers.
