what is distributed generation
What is Distributed Generation?

Distributed generation is a concept where smaller, highly efficient power plants are installed along the existing grid, close to the end-user customer. It is similar in concept to the move from large central computers to desktop computers on a network.

Sea Palms Resort

why is distributed generation occurring
Why is Distributed Generation Occurring?
  • There are localized shortages of electricity in this country, particularly in California and the Northeast. The ability to quickly build power plants to provide needed power is attractive.
  • It is getting increasingly difficult to site new power plants near population centers due to air quality concerns.
  • Deregulation is opening up new markets and new players on those markets, all of whom are looking for tools that will make them as competitive as possible.
  • National Security

Sea Palms Resort

distributed generation in the southeast
Distributed Generation in the Southeast?
  • Electricity in the Southeast is relatively inexpensive, but recognized as being less clean then alternative energy sources. Distributed Fuel Cells are one potential source for clean power, but not cost competitive today with fossil fuel plants.
  • Today, renewable energy implementations are relatively few in the Southeast, but do exist… utilizing landfills and reciprocating engines… participating in the Green Power Program.

e.g. Santee Cooper - Horry County Landfill

Anderson County Landfill

Sea Palms Resort

distributed generation in the southeast1
Distributed Generation in the Southeast?
  • We need more reliable power alternatives for business and mission critical environments. Power security and inclement weather (ice, wind, thunder & lightning, etc.) present economic and security threats to our region.
  • The Southeast has many feed stocks for biomass and large-scale wastewater management facilities upon which to leverage for green power. These environments present opportunities for research, demonstration, public awareness and ultimately lower cost implementations.

national security
National Security
  • Growing Concern about Power Security
    • Reliability of National Grid (Blackouts)
    • Vulnerability of National and Regional Grid, in particular Generation and Transmission Facilities.
  • Business Operations are vulnerable to power availability fluctuations due to weather and local load factors.
    • Not just a big business concern anymore… an “Internet connected society” needs reliable power… in the home, in the office – 7 x 24.

distributed generation scenarios
Distributed Generation Scenarios


  • Remote Generation (on or off grid)
  • Export to System Side (sell the excess power back to the utility)
  • Backup Generation (replacement of diesel generators)

System Side

  • Energy and Capacity (e.g. green power program)
  • Ancillary Services (in support of distributed generation)
  • Local Reliability Generation Services (in mission critical areas, e.g. hospitals).

Hotel and Hospitality Business

Starwood began using fuel-cell energy in 2003 at its Parsippany and Edison, N.J., properties,

They have cut about 5% from the hotels' energy costs.

The DFC300A uses natural gas that is supplied by New Jersey Natural Gas of Wall, N.J. H.T. Lyons, a PPL subsidiary based in Allentown, Pa., was responsible for the installation.The New Jersey Clean Energy Program provided $860,000 in funding to PPL as part of its incentive program to encourage the use of clean and efficient technology.

wastewater treatment facilities
Wastewater Treatment Facilities
  • Industrial and municipal wastewater treatment facilities with anaerobic gas digesters present an important opportunity.
  • The methane generated from the anaerobic gas digestion process is used as fuel for the fuel cell power plants, which in turn generates the electricity to operate wastewater treatment equipment at the facility.
  • Wastewater treatment gas is a renewable fuel eligible for government incentive funding for project installations throughout the world.
  • There are over 550 municipal wastewater treatment facilities in the U.S. that are capable of producing enough methane from anaerobic gas digestion to fuel a 250-kilowatt or larger fuel cell power plant.

  • Using digester gas from King County's South Treatment Plant in Renton, Wash., the Company's DFC1500 power plant provides one megawatt of electricity for the wastewater treatment facility, enough to power 1,000 households.
  • The electricity generated by the Direct FuelCell (DFC) power plant is used to run some of the treatment plant equipment and the waste heat is used to produce hot water for the treatment facility.

obstacles to adoption
Obstacles to Adoption
  • Low volume production results in high initial capital equipment costs.
  • Interconnection standards, exit / stand-by charges, net metering.
  • No clear correlation between spot market natural gas prices and grid-delivered electricity rates, making business unfavorable for distributed generation.
  • Rate definition process can cause delays or lags in fuel price impact on utility rates.
  • Government incentive programs can be overly complex.

Public and industry awareness of

reduced emissions unrecognized…

… understanding of risk mitiga-

tion from on-grid dependency

and overall power security risks

not understood or quantified.

exercise install a residential pemfc solution
Exercise - install a residential PEMFC solution

Fuel: Natural Gas - Fuel cell will require a ¾” Natural Gas supply line. Delivery pressure same as typical home appliance.

Water - Fuel cell will require a ¼” water supply line. A water treatment panel will be installed inside the residence or business, and the installer will run an additional ¼” line to each fuel cell from this water treatment panel.

Drain - The unit produces a small amount of condensate. This condensate will drip from a ¼” diameter plastic hose. The condensate can drain to the ground or a nearby sanitary line.

Electric - Fuel cell must be connected to an existing 120/240V electric panel. This is where the fuel cell will import power into the residence or business. A 1-1/2” conduit must be run from the fuel cell to the panel. This conduit will carry grid-sensing and power conductors. An FC disconnect is installed near the unit which serves to isolate the fuel cell for service or in the event of a power outage.

Heating System - For a Combined Heat and Power Configuration (CHP), a separate CHP heating loop will be needed. This loop is typically a 1-1/4” insulated copper line that will circulate a water-glycol mixture to and from the fuel cells. This loop is called the CHP loop. It will carry heat from the fuel cell to a water storage tank that will be located inside the residence or business. The tank is similar to a residential hot water heater and will supplement your existing hot water heater or boiler.

Phone Line - A dedicated analog phone line will be required to allow the fuel cell to relay data to the manufacturer.

Foundation - Fuel cell can sit on any stable and level surface. A concrete pad is optimum, but a concrete paver, asphalt, or gravel base is acceptable.
