California’s primary energy policy and planning agency
Underground reservoirs that produce either dry steam or a mixture of steam and water.
Industry:Energy
The maximum amount of a pollutant legally permitted to be discharged from a single source.
Industry:Energy
An entity that purchases electrical energy or services from the Power Exchange (PX) or through a bilateral contract on behalf of end-use customers.
Industry:Energy
The real-time change in generation output or demand requested by the ISO to maintain reliability of the ISO-controlled grid. Sources of imbalance energy include regulation, spinning and non-spinning reserves, replacement reserve, and energy from other generating units that are able to respond to the ISO's request for more or less energy.
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
A body of water confined by a dam, dike, floodgate or other artificial barrier.
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
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.
Industry:Energy
The amount of energy consumed in the form in which it is acquired by the user. The term excludes electrical generation and distribution losses.
Industry:Energy
Using less energy/electricity to perform the same function. Programs designed to use electricity more efficiently: doing the same with less. For the purpose of this paper, energy efficiency is distinguished from DSM programs in that the latter are utility-sponsored and -financed, while the former is a broader term not limited to any particular sponsor or funding source. "Energy conservation" is a term which has also been used but it has the connotation of doing without in order to save energy rather than using less energy to do the some thing and so is not used as much today. Many people use these terms interchangeably.
