Initial Daily Settlement |
Initial daily settlement is a calculation of load settlement conducted
within a short time after the day of flow, such as one to two days.
Initial daily settlement, by virtue of its timing, does not use
consumption information from cumulative (monthly, bimonthly, or longer)
meter readings, nor does it use interval data retrieved on a monthly
basis. |
Initial Monthly Settlement |
Initial monthly settlement is a calculation of load settlement for the preceding month. |
Interconnected Electric System |
All electric energy transmission facilities and all distribution systems in Alberta (or any
other jurisdiction or combination of jurisdictions) that are interconnected. |
Interim Adjustment Charge |
Interim adjustment charge is the cost difference between Interim and
Initial settlement. Interim settlement occurs 3 months after the month
of consumption. |
Interim Settlement Run |
The Interim Settlement Run is three months after the Initial Settlement
Run. Interval Period. The number of minutes between readings. DIM Report
= 15 minutes. WSI Report = 60 minutes. |
Interval End Time |
Date and end time of the interval the settlement data is for. The
standard Date format has been defined as: YYYYMMDDHHMISS. |
Interval (Time-of-Use) Meter |
A meter that measures at intervals of 60 minutes or less the amount of electric energy
consumed by a customer and satisfies the standards for revenue collection under the
Electricity
and Gas Inspection Act (Canada)
and the
Weights and Measures Act (Canada). |
Investor Owned Utility (IOU) |
A utility whose stock is usually publicly trade and which is organized as tax-paying business and financed by the sale of
securities in the capital market. It is regulated and achieves allowed rate of return. |
Interval Period |
The number of minutes between readings. DIM Report = 15 minutes. WSI
Report = 60 minutes. |
IPCCAA |
IIndustrial Power Consumers Association of Alberta
is an organization of large industrial customers whose mission is
to take a leadership role in ensuring that a competitive marketplace exists for electrical services. It comprises
companies from such key industries as oil and gas, forest products, petrochemicals and steel. |
IPP |
Independent Power Producer. A privately owned power generating facility which may be connected to a utility system to supply electricity for domestic or export markets.
|
IPPSA |
The
Independent Power Producers' Society of Alberta
- representing competitive power producers, wholesale and retail marketers,
suppliers, engineering firms, consultants and contractors. |
ISO |
Independent System Operator. |
| J |
|
Joule |
Unit of work or energy equal to the work done by a force of one Newton acting through a distance of one meter. |
| K |
|
kV |
abbreviation for kilovolt and equal to 1000 volts. |
kVa |
Abbreviation for kilovolt-ampere, unit of electrical power (Demand for the interval period) equal to 1000 volt-amperes. |
kVah |
kilovolt-ampere hour (Consumption) for the interval period. |
kVAr |
abbreviation for kilovar. A unit of ac reactive power equal to 1000 vars. |
kVarh |
kilovolt-ampere Reactive hour (Consumption) for the interval period. |
kW |
abbreviation for kilowatt. A unit of power equal to 1000 watts. One thousand Watt s flow
of electric energy is required to light 10 100-watt light bulbs or equivalent to 1.34 horse power. |
kWh |
abbreviation for Kilowatt-hour. This is the normal quantity used for
metering and billing electricity customers. The price for a kwh varies from approximately 5 cents to 15 cents. At
100% conversion efficiency, one kWh is equivalent to about 4 fluid ounces of gasoline, 3 cubic feet natural gas, or
1/4 pound coal. An average household will use between 800 - 1300 kWh per month depending upon geographical area. |
| L |
|
Last Meter Dial Reading |
The previous dial reading taken from the meter. |
Last Reading Datetime |
Date and time of last reading. The standard Datetime format has been defined as: YYYYMMDDHHMISS. |
LDCs |
Local Distribution Companies. |
Line Loss & Ufe ($) |
The line loss and UFE monthly charge is the sum of the energy at the hourly power pool price. |
Line Loss & Ufe (kwh) |
Line Loss is a settlement amount of energy allocated to sites at a fixed
rate. Loss factors differ between load types (called loss groups).
Unaccounted for Energy (UFE) is a settlement amount allocated to sites
and represents energy not accounted for by meters and losses. UFE is
calculated hourly by the LSA for each Zone and the amount is distributed
evenly to all sites for that hour (except for TA and direct connect sites). |
LL |
Load Limiter - a device that allows for a limited amount of electricity to flow to a residential customer. |
Load Profile |
A load profile is a series of load or consumption amounts for each
interval over a particular time period. The intervals are one hour, so
that the profile may be considered either as average load (kW) or total
consumption (kWh) for each interval. The profile may be expressed either
as the average per Customer or as the total load for each interval. |
Load Profile Shape |
A load profile shape is a normalized load profile. Specifically, the
energy consumption in each interval (hour) is expressed as a fraction of
the total energy consumption for the time span of the profile. |
Load Research Shape |
A Yes (Y) or No (N) flag noting a customer in the load research sample. |
Load Shedding |
Removal of pre-selected customer demand from a power system, as a result of the
occurrence of an abnormal condition, in an effort to maintain the integrity of the
system and minimize overall customer outages. |
Load Settlement |
Calculation by LSA of the consumption at each unit of the settlement interval (hourly) for each retailer operating within each settlement zone. |
Load Settlement Access |
Load Settlement Access is the fee charged by an LSA per a site for determining its load settlement. |
Load Settlement Agent (LSA) |
The party conducting load settlement calculations for a particular zone.
The LSAs currently operating within Alberta are ATCO; ENMAX; EPCOR;
FORTIS; Lethbridge; Crowsnest Pass; Red Deer; Ponoka; Fort MacLeod; Cardston. |
Local Access Fee |
The Franchise Fee paid by utilities to local governments in lieu of access to municipal right-of-way and property taxes on linear property. |
Loss |
Loss is the electrical energy used to move electricity over the
distribution system to the Customer. The loss percentage varies by
profile class and by wire service provider (WSP). Typically it is 2.5% - 6.5%. |
Loss Group Code |
The site's Loss Group code assigned by the Wire Service Provider. Loss
Group codes have specific loss calculations. |
Loss kWh |
Settled loss allocation for the site for the day. |
LSA |
Load Settlement Agent - The party conducting load settlement calculations for a particular zone. The LSA's currently operating within Alberta are ATCO; ENMAX; EPCOR; AQUILA; Lethbridge; Crowsnet Pass; Red Deer; Ponoka; Fort MacLeod; Cardston. |
