1. 1 Frederick R. Broome, Jr., P.E. Director, Installation & Environment Division On behalf of the MCLBA Energy Team of Hubert “Ski” Smigelski, Lt. Cmdr. Jeff Benjamin, CEC, P.E., Mike Henderson, P.E., Nancy Hilliard, P.E., Eddie Hunt, CEM, & our CHM2Hill partners Net Zero Energy Plan for MCLB Albany, GA

2. Overview Defining Net Zero Energy Achieving Net Zero – Current Renewable Energy Projects – Future Renewable Energy Projects Future Energy Profile “Speedbumps” to Success 2

3. Net Zero Energy Definition Assumed Definition – MCLB Albany will be a net zero energy installation by the year 2020 when it produces as much energy on- site from renewable energy generation or through the on-site use of renewable fuels, as it consumes in its buildings and facilities. Does not include: – Water – Vehicles – Waste 3 Energy Consumption Renewable Energy Generation Energy Consumption Renewable Energy Generation Net Zero Energy

4. 4 The “Gap” 30% Energy Intensity Reduction Renewable Energy Generation Multiple mandates to conserve & use renewables, but SECNAV goal of 50% of installations at Net Zero by 2020 closes the “gap” between them

5. Achieving Installation Net Zero A balanced combination of reducing energy intensity while also increasing renewable energy generation – Diversity is important For installation-wide net zero, largest impact comes from large scale industrial scale renewable energy generation platforms – A few large scale projects vs. lots of little projects Collaboration with local industry and energy providers – The answer isn’t always inside the fence 5

8. Future Renewable Energy Systems Landfill Gas, Phase 2 – 2 nd, 1.9 MW generator with waste heat recovery system Ground Source Heat Pump – Multiple well fields for key areas of high energy consumption Biomass – Local industry provider has biomass plant which also generates steam – Albany to provide steam to electricity generator Other Renewable Energy Sources (Low Feasibility for Albany) – Wind – Solar – Geothermal to Electricity – Fast Pyrolysis 8

9. Biomass – State Level The State of Georgia produces over 22 million tons biomass per year. Georgia is prioritizing energy resource development statewide. Only second to improved energy efficiency is “utilization of GA significant biomass resources.” (Georgia State Energy Strategy)

10. Biomass – State Level Feasibility of Generating Electricity from Biomass Fuel Sources in Georgia; The University of Georgia Center for Agribusiness and Economic Development, 2003 Georgia’s most “biomass rich” land lies within a ~50 mile radius of Dougherty County.

16. Constraints, Restraints & Challenges to achieving Net Zero Getting data/control systems that are approved to work inside the firewall/DIACAP approval process Support within the government to accurately estimate savings & feasibility of cutting edge technology Measurement & Verification Contractual, fiscal and technical complexity of large scale renewable projects Lack of state tax incentives Challenge of grouping various energy programs together (ESPC, ECIP, EIP, ESTCP, etc...) Contractual & fiscal challenges of partnerships with local industry and local government State law (Territorial Act) 16

18. Back Up Slides 18

19. Wind Pre-Screening One of lowest potential regions in the country

20. Geothermal Heat Pre-Screening One of poorest potentials in the country *Note Screening is for direct use of heat, not GSHP Requires approximately 10km of boring

21. Solar PV Pre-Screening Average solar potential compared to much of the country.
