PUBLIC-PRIVATE PARTNERSHIPS PAVE THE WAY
A combination of federal and state policy priorities, combined
with the private sector’s access to equity and ability to utilize
available tax credits, created the perfect opportunity for
Raleigh to advance its efforts with renewable energy
at no cost to taxpayers. Working closely with Progress
Energy, the City relies on private sector expertise to
plan, design and install projects such as the 1.3MW
ground-mounted solar photovoltaic Neuse River
Solar Farm and the 500kW Raleigh Convention
Center rooftop solar array.
RALEIGH’S RESILIENT ENERGY FUTURE
Raleigh’s resilient future requires rethinking its reliance
on existing power sources and distribution systems. The need
for greater flexibility and better integration of renewable
resources in the power grid is apparent. By participating in Rocky
Mountain Institute’s eLab research and pilot project, Raleigh
is helping accelerate electrical innovation at the distribution
edge. Investing in geothermal heating and cooling systems, solar
thermal technology and recovering methane for profit expands
the City’s energy portfolio while providing a model for others.
EXPLORING AN ENERGY FARM
The City is exploring the feasibility of multi-purposing the Wrenn
Road and Neuse River Wastewater Treatment Plant acreages,
and the closed Wilders Grove landfill, into functional energy
farms. Through its numerous partnerships, City leaders are taking
a closer look at producing energy through small wind, biomass
and harnessing effluent discharge while proceeding with biofuel
crops and large-scale solar photovoltaic installations.
SMALL HYDRO POWERS TALK ABOUT FALLS LAKE POTENTIAL
City leaders are also evaluating the feasibility for small hydropower
generation through Falls Lake water releases, potentially based on
an outlet tower turbine concept as constructed at Jordan Lake.
A diversified clean energy economy is vital to Raleigh’s future.
RALEIGH CONVENTION
CENTER SOLAR ARRAY
DISPLAYS ADVANTAGE
The

®
Silver
certi-
fied Raleigh Convention
Center’s 500kW rooftop
solar array is the second-
largest
convention
center
solar array in the nation and the
City’s largest urban solar energy system.
Covering approximately 60 percent of
the roof, the 2,080 panels are expected to
produce 750,000 kWh of electricity each
year, roughly equivalent to the annual
energy use of 70 homes in North Carolina.
This production reduces CO2 emissions by
about 500 tons annually, the equivalent to
eliminating CO2 emissions from about 100
passenger vehicles.
FLS Energy and PowerWorks Electric
financed, engineered, built, own and
operate the solar system. Progress Energy
buys electricity generated by the array
and uses it to serve its customers. FLS
Energy is leasing the Convention Center
rooftop space from the City for $3,000
annually to operate the solar array, and
the City will have an opportunity to pur-
chase the array at the end of the lease
agreement.
