• Renewable Portfolio Standard Class II Suspension Announced (August 23, 2012) 

    As directed by EEA Secretary Richard Sullivan, DOER Commissioner Sylvia has suspended consideration of RPS Class II Statement of Qualification Applications for woody biomass generation units which support pre-1998 renewable energy generation. DOER will soon begin a rulemaking on the eligibility of woody biomass for Class II to incorporate applicable provision of the new Class I regulation that assures qualified biomass units contribute to greenhouse gas reductions and protect forestlands.

    Do the Northeast States' air emission regulations and safety certifications for residential and institutional-scale biomass boilers and furnaces pose a barrier to the creation of a viable northeast market for domestic and non-U.S. biomass heaters and boilers? If so, what strategic actions could be taken to reduce barriers and create a more attractive regional market for high performance biomass boilers, manufactured domestically or abroad? DOER, in coordination with the Northeast States, contracted the Coalition of Northeast Governors (CONEG) Policy Research Center, Inc. to develop a report that presents an objective analysis on these issues.
