California’s primary energy policy and planning agency
The emissivity of a material, expressed as a fraction. Emittance values range from 0.05 for brightly polished metals to 0.96 for flat black paint.
Industry:Energy
A provision included in some power sale contracts that lets the supplier stop delivery when the power is needed to meet certain other obligations.
Industry:Energy
Power capacity or energy obtained by one utility from others under purchase or exchange agreement.
Industry:Energy
The capacity for doing work. Forms of energy include: thermal, mechanical, electrical and chemical. Energy may be transformed from one form into another.
Industry:Energy
(energy calorie: small "c" as opposed to food Calorie: capital "C") Any of several approximately equal values of heat, each measured as the quantity of heat require to raise the temperature of 1 gram of water by 1 degree Celsius from a standard initial temperature, esp. from 3.98 degrees Celsius. 14.5 degrees Celsius, or 19.5 degrees Celsius, at 1 atmosphere pressure. A calorie is the unit of heat equal to 4.184 joules.
Industry:Energy
A body of water confined by a dam, dike, floodgate or other artificial barrier.
Industry:Energy
A requirement in the Building Energy Efficiency Standards that a proposed building be designed to consume no more than a specified number of British thermal units (Btus) per year per square foot of conditioned floor area.
Industry:Energy
The amount of electric power for which a generating unit, generating station, or other electrical apparatus is rated either by the user or manufacturer. The term is also used for the total volume of natural gas that can flow through a pipeline over a given amount of time, considering such factors as compression and pipeline size. There are various types of electricity capacity: Dependable Capacity: The systems's ability to carry the electric power for the time interval and period specific, when related to the characteristics of the load to be supplied. Dependable capacity is determined by such factors as capability, operating power factor, weather, and portion of the load the station is to supply. Installed (or Nameplate) Capacity: The total manufacturer-rated capacities of equipment such as turbines, generators, condensers, transformers, and other system components. Peaking Capacity: The capacity of generating equipment intended for operation during the hours of highest daily, weekly or seasonal loads. Purchased Capacity: The amount of energy and capacity available for purchase from outside the system. Reserve Capacity: Extra generating capacity available to meet peak or abnormally high demands for power and to generate power during scheduled or unscheduled outages. Units available for service, but not maintained at operating temperature, are termed "cold." those units ready and available for service, though not in actual operation, are termed "hot."
Industry:Energy
The amount of money owed by an electric customer for kilowatt-hours consumed.
Industry:Energy
A percentage that tells how much of a power plant's capacity is used over time. For example, typical plant capacity factors range as high as 80 percent for geothermal and 70 percent for co-generation.
