Net Zero Energy Plan for

MCLB Albany, GA

Overview

Defining Net Zero Energy

Achieving Net Zero– Current Renewable Energy Projects– Future Renewable Energy Projects

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

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

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

Future Renewable Energy Systems

Landfill Gas, Phase 2– 2nd, 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

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)

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.

Point of Net Zero Energy

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)
