acua s solar portfolio
ACUA’s Solar Portfolio
  • 2,700 solar panels installed at Wastewater Treatment Facility in five arrays:two roof top, two ground mounts and one canopy array
  • 500 kW system owned and maintained by ACUA
  • Operational in 2006
  • $3.25 million project
  • $1.9 million CORE rebate from NJBPU
  • Electricity from the solar arrays also create SRECs (Solar Renewable Energy Credits)
  • ACUA’s solar arrays have generated over 2.4 million kWh of electricity and saved the ACUA over $1.3 million
landfill gas to electric
Landfill Gas to Electric
  • ACUA project fully funded by a third party;

AC Landfill Energy, LLC, a joint venture of

DCO Energy and South Jersey Industries

  • Methane gas powers 5.4 Mw engine generators (combined 1.6 Mw generator

and two 1.9 Mw generators)

  • 1.6 Mw of energy produced powers all

of ACUA’s Environmental Park. Excess energy sold to PJM Grid

  • Capable of producing enough energy to power 3,434 homes
  • Excess energy from the LFGTE Project is sold to The Borgata Casino Spa & Hotel
  • $513,200 incentive from NJBPU; $375,000 NJDEP grant NJEDA low interest loan for remaining $ 2 million
  • Estimated annual savings - $550,000
  • Greenhouse gas credits are registered on the Climate Action Reserve
geothermal energy
Geothermal Energy
  • Geothermal energy is the only renewable energy source created naturally by the earth itself.
  • Well-designed geothermal systems are among the most environmentally benign sources of energy.
  • A closed loop geothermal unit provides the heating and cooling for the Authority’s administrative office or Geo Building.

Geothermal Office Building

Reduces Electric Cost by 20%

alternative fuels
Alternative Fuels


  • ACUA operates largest

biodiesel fleet in New Jersey

  • Entire ACUA diesel fleet, 106 vehicles,

runs on a B5 blend of biodiesel

  • In addition, 23 municipal vehicles and

four county vehicles use biodiesel

and fill-up at the ACUA

compressed natural gas cng
Compressed Natural Gas (CNG)
  • ACUA is building a CNG filling station, partially funded by a DOE Clean Cities grant
  • Transition collection fleet to CNG
  • First of its kind in southern NJ
  • Operational by the Fall of 2010
  • Will have public fleet access
compressed natural gas cng1
Compressed Natural Gas (CNG)
  • Why CNG?
  • Cheaper - Natural gas is between $0.50 and $1.00 cheaper than diesel per gallon equivalent. ACUA estimates that it will save $10,000 per truck for the first year based on the Price differential b/w NG & Diesel plus the Alternative Fuel Tax Credit of $0.50 per GGE for fuel used and dispensed. The Alternative Fuel Tax Credit is due to expire 12/31/2010 but there are two Bills in Congress that may extend it 2019 or beyond.
compressed natural gas cng2
Compressed Natural Gas (CNG)
  • Cleaner – NG burns cleaner than diesel/gasoline creating 80% less ozone forming emissions
  • Less Expensive
  • Produced domestically
electric vehicles charging stations
Electric Vehicles & Charging Stations
  • The ACUA unveiled three electric charging stations in July of 2009 on both its Solid Waste and Wastewater Treatment sites
  • The stations are capable of charging at 110 volts or 220 volts
  • The ACUA owns a low-speed GEM electric car and a 2000 Ford Ranger EV
  • The Ranger gets 61 miles on a single charge and takes between 6 and 8 hours to charge
  • Estimated cost of $0.04 per mile
  • All electricity produced for the vehicles comes from renewable sources making them zero-emission

planning for a greener future solar on the landfill
Planning for a greener future: Solar on the landfill

Utilizing the landfill area for solar arrays

  • 15 acre area of ACUA landfill

  • Byproduct: electricity and syngas
  • What is plasma gasification?
  • Plasma gasification differs from incineration
  • Plasma described as “fourth state of matter”
  • No oxygen introduced
  • Higher temperatures, high energy state
