Jersey Atlantic Wind Farm
M.A. Mortenson Company
Atlantic City, NJ
8
Jersey Atlantic Wind Farm
  • The first coastal wind farm built in the
    Northeast and the first wind farm in New Jersey
  • 12.5 million project
  • Project fully funded by a third party NJBPU
  • Five General Electric 1.5 mW turbines
  • 7.5 mW of electricity during peak operations
  • Enough to power 2,500 homes
  • Provides almost 60 of the yearly electrical
    energy needs for the plant.

9
ACUAs Solar Portfolio
  • 2,700 solar panels installed at Wastewater
    Treatment Facility in five arraystwo 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)
  • ACUAs solar arrays have generated over 2.4
    million kWh of electricity and saved the ACUA
    over 1.3 million

10
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 ACUAs 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 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 Authoritys
    administrative office or Geo Building.

Alternative Fuels
Biodiesel
  • 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

14
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

15
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.

16
Compressed Natural Gas (CNG)
  • Cleaner NG burns cleaner than diesel/gasoline
    creating 80 less ozone forming emissions
  • Less Expensive
  • Produced domestically

17
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

18
Dedicating Employee Resources to Sustainable
Practices
  • Created an RD department dedicated to
    researching greener business practices and energy
    sources, with a focus on
  • New technologies/project analysis
  • Available grants and incentives for green
    projects
  • Regulatory environment
  • Monitoring efficiencies of implementations
  • Spreading the green philosophy through the
    organization, and inspiring other departments to
    embrace new, sustainable ideas (i.e. IT
    department)
  • Hiring interns to gain green collar
    experience, including an intern in the
    maintenance facility to work on the areas first
    electric vehicle

19
Greening the Office PlaceEnergy Water
Conservation
  • Waterless urinals, faucet sensors and low-flow
    aerators
  • Replaced CRT monitors with energy efficient LCDs
  • Computer monitors utilize energy saving sleep
    mode
  • Reduced number of servers by 1/3
  • Energy Star certified appliances and office
    equipment and high efficiency lighting
  • Energy Audit done by Rowan University students to
    determine opportunities for additional
    improvements in efficiency
  • ACUA promotes and provides assistance to local
    municipalities applying for NJ Energy Audit
    program

Joining CCX CAR
  • In February of 2007 ACUA gained membership in
    CCX-- the worlds first legally binding
    rules-based GHG emission allowance trading
    platform
  • First in New Jersey
  • Committed to cutting GHG emissions by 6 of 2000
    levels by 2010
  • Reached this goal by December 31, 2008 and have
    continued to make GHG reductions each year
  • In October of 2009, ACUA gained membership in
    Climate Action Reserve (CAR)
  • CAR encourages voluntary reporting and has
    developed a protocol to track GHG emissions and
    reductions
  • ACUA has registered carbon offset credits from
    capturing landfill gas on CAR
  • Each credit has a market value which provides
    ACUA funds to support more green initiatives

23
Community Outreach Education
  • Getting the public educated about sustainability
    in the home and office, and acting as a model for
    other organizations
  • Facility tours
  • Community Events
  • Hosting workshops and seminars on
  • alternative energy
  • Newsletter
  • Social networking
  • Fact sheets and educational materials
  • Annual Earth Day celebration
  • Clean Communities Program
  • Water Use it Wisely Campaign
  • Environmental Stewards Program

24
Energy Curtailment
  • Reducing electricity use in response to high
    prices or grid reliability problems
  • ACUA will curtail use when called upon for up to
    15 minutes
  • Replaces the need for standby generation
  • While participating in the Spinning Reserves
    program from 2008 2009 the ACUA earned
    approximately 25,000

25
Planning for a greener futureTruck Wash
  • Treat and reuse water from previous washes
  • Up to 80 of the water is reused
  • Save money and reduce the potable water needed
    to wash vehicles
  • Solar hot water heating system included
  • Up to 800 gallons of preheated water can be
    stored
  • Open to outside fleets for use

26
Planning for a greener future Plug in Hybrids
One of ACUAs Ford Escape Hybrids will be
converted to a plug in hybrid
27
Planning for a greenerfutureV2G Technology
MAGICConsortium Partners
  • Utilizes the stored energy in electric vehicle
    batteries
  • Contribute electricity back to the grid upon
    demand
  • Customers earn revenue for energy sold back
  • Increases grid efficiency and reliability
  • Makes it possible to use intermittent renewable
    sources like wind and solar to power vehicles

ACUA is a partner in the Mid-Atlantic Grid
Interactive Cars Consortium (MAGICC), created to
test, develop and demonstrate V2G
technology www.magjicconsortium.org
28
Planning for a greener future Solar on the
landfill
  • Utilizing the landfill area for solar arrays
  • 15 acre area of ACUA landfill
  • 2-3 megawatts could be installed
  • Power can be sold to customer adjacent to
    property
  • Revenue from SRECs and electricity offset capital
    cost for ACUA or 3rd party
  • Should be operational in 2010

29
Planning for a greener future Plasma Gasification
  • ACUA is exploring plasma gasification as a way to
    divert material from the 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
  • Plasma torches break trash into atoms that
    compose it
  • Efficient 46 of waste converted to energy

Communicating Sustainability
5 Keys to pushing sustainability in 2010
  • Leadership Innovation
  • Partnerships
  • Reticulating sustainable initiatives with core
    company values
  • Leveraging consumer concern for the environment
    and foreign sources of energy
  • Using social media tools and web content
