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 onsite from renewable energy generation or through the
on-site use of renewable fuels, as it consumes in its
buildings and facilities.

The “Gap”
30% Energy Intensity Reduction
•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
–

For installation-wide net zero, largest impact comes from
large scale industrial scale renewable energy generation
platforms
–

Diversity is important
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

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
Georgia’s most
“biomass rich” land
lies within a ~50 mile
radius of Dougherty
County.


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)
