1 Creating A Cleaner Energy Future For the Commonwealth COMMONWEALTH OF MASSACHUSETTS Deval L. Patrick, Governor Richard K. Sullivan, Jr., Secretary Mark Sylvia, Commissioner Northeast Biomass Heating Expo Renewable Biomass Thermal Energy in Massachusetts Saratoga Springs, NY April 4, 2013 Dwayne Breger, Ph.D. Director, Renewable and Alternative Energy Division

2 DOER Mission Creating a Cleaner Energy Future for the Commonwealth Ensure deployment of all cost effective energy efficiency Maximize development of clean energy resources Create and implement energy strategies to assure reliable supplies and improve the cost of clean energy relative to fossil fuel based generation Support Massachusetts clean energy companies and spur Massachusetts clean energy employment

3 Primary Drivers for Clean Energy Policy (The Acts of 2008) Green Communities Act Expands EE delivery dli mechanisms and goals RPS expansion (APS) and strengthening targets Net metering provisions Wind Siting Commission Global Warming Solutions Act 2020 commitments 10 25% below 1990 levels 2050 commitments 80% or more below 1990 levels Oceans Management Act Provides zoning like planning of state waters Identifies presumptive areas for wind development Clean Energy Biofuels Act Mandate for advanced biofuels Paves way for transition to LCFS 3

5 Key Provisions to the Regulation for the Qualification of Woody Biomass into the RPS Program (electricity) Eligible ibl Forest tbiomass and Forest tsustainability Carbon Accounting 50% reduction of GHG Emissions by 20 yrs Differentiates biomass residues and thinnings Overall Efficiency Criterion 50%Efficiency Threshold; 60%for full REC credit

6 RPS Rulemaking Policy Findings Biomass can contribute to MA clean energy and climate commitments. Sustainable biomass resource is renewable, but exhaustible (especially residual supplies). So, question is how best to use the limited biomass we have to maximize its benefits. And for policymakers, what policies can best achieve this outcome. This process has significantly opened the opportunities to explore policy to promote biomass thermal.

7 Thermal fuel use in Massachusetts Space heating and cooling & water heating = 54% total building energy use 1/3 of homes heating system > 15 years old 7

9 Renewable thermal technologies Biomass: highly efficient, variable systems with low air emissions Using wood or other biomass (grasses), in the form of cordwood, pellets or chips Solar Hot Water: collectors providing additional heat for space heating, domestic hot water, process heat or other low temperature heating needs Heat pumps: highly efficient systems of compressors/expanders and heat exchangers using the thermal energy of ambient air, water or underground to heat and cool buildings Attention: account for electricity consumption by pumps and compressors Advanced biofuels: biomass derived liquid fuels delivering at least a 50% reduction in lifecycle GHG emissions Biogas: digester gas from Anaerobic Digestion or capped landfills used for heating purposes at the site of capture, or by mixing it in the natural gas pipelines. 9
