Library

The information library for CHP systems is organized in the following major sections:

MAC Project Documents, Publications, Reports, and Other Documents -- Final reports, papers published in magazines and journals, and presentations made at conferences by The Midwest CHP Technical Assistance Partnerships are available here to keep you abreast of the latest developments in CHP systems in the Midwest.

CHP Technical Assistance Partnerships (TAPs) -- Provides information about DOE's eight TAPs established in various regions of the country

Information Resources of DOE's Distributed Energy Program -- Provides information in the following areas:

Database of State Incentives for Renewable Energy --The Database of State Incentives for Renewable Energy (DSIRE) is a comprehensive source of information on state, local, utility, and selected federal incentives that promote renewable energy.

DG Regulatory Project Guide -- Database organized by state provides distributed energy information for emissions regulations, siting regulations, regulatory codes, "exit fees", standby rates, and economic incentives.

Regulatory Requirements Database for Small Electric Generators -- The Regulatory Requirements Database for Small Electric Generators is an online resource that provides basic information, on a state-by-state basis, about permit requirements for distributed generation projects. Additionally, it provides information on "exit fees," standby rates, and economic incentives, if information is available. Each state page provides information for emissions regulations, siting regulations, and regulatory codes. The database is continuously updated and maintained by Energy and Environmental Analysis, Inc., for the U.S. Department of Energy and Oak Ridge National Laboratory.

FAQ's -- provides answers to frequently asked questions about CHP.

Glossary -- Definitions of the terminology and abbreviations used in this Website

     Glossary

    Absorption chiller

    Water chiller based on absorption of refrigerant vapor into a liquid solution, pumping of the solution to elevated pressure, and the release (desorption) of refrigerant vapor through the addition of heat: such as the hot exhaust gases from electric generation

    CHP

    Cooling, heating, and power

    Demand charge

    Charges for the use of electricity based on the maximum power requirement, electrical demand, during a specified period of time, typically a month ($/kW)

    Desiccant

    A solid or liquid material with an affinity for absorbing water molecules

    DG

    Distributed generation: generating power on-site or near site

    Engine-generator

    Electrical generator using a reciprocating, Stirling, or rotary engine

    Enthalpy wheel

    Heat exchanger rotating through building supply and exhaust air flows to transfer energy from one air stream to the other

    Evaporative cooling

    Cooling of air through the evaporation of water from a spray or wetted membrane; direct evaporative cooling adds water to the supply air while indirect evaporative cooling adds water to the exhaust air and incorporates a heat pipe or thermal wheel for indirect cooling of the supply air

    Fuel cell

    Device for producing electricity using a chemical process rather than conventional combustion processes with electric generators

    HVAC

    Heating, ventilating, and air conditioning

    Heat wheel

    Heat exchanger rotating through building supply and exhaust air flows to transfer heat from one air stream to another

    IAQ

    Indoor air quality

    kW

    Kilowatt, a unit for measuring electric power. It is equal to 1000 watts

    Latent cooling load

    Amount of cooling required to reduce humidity of air in conditioned space to specified level for comfort

    Line losses

    Electric energy lost as heat in power transmission lines

    MW

    Megawatt, a unit for measuring electric power. It equal to 1000 kW

    Microturbine power generator

    Turbine-engine driven electrical generator with output power under 300 kW

    Power reliability
