Glossary| Term | Description |
|---|---|
| Daily Consumption Meter (DCM) | Daily cumulative meter consumption to Retailers and Settlement. |
| Daily Interval Meter Readings (DIM) | Daily Interval Meter Readings to Retailers and Settlement. |
| Daily Load Chart | Load is a general term referring to size and represents average consumption rate (units are MW). Daily average load is calculated by total daily consumption divided by 24 hour period. The Daily Load chart shows what your consumption trend has been over the past couple of months. The peak/min trend lines mark out the band of variability of the load on a daily basis. |
| Daily Load Factor Chart | Load factor is the ratio of average load divided by max load. Load factor represents how consistently close to full load equipment is being operated at. A load factor that falls under 75% mean a large site has dropped in load that day. |
| Daylight Savings Time | Times refer to times on the prevailing clock, standard or daylight time depending on the season. Clock adjustments for daylight savings follow the standard used by the Pool. Specifically, at the time of the springtime change, the hour ending 2AM does not exist. Hour ending 3AM follows hour ending 1AM. At the time of the fall time change, hour ending 2AM occurs twice, with the second denoted by an asterisk (*). For transactions using this convention, an "Hour Ending" field will exist that contains an asterisk following the hour 02 value (i.e. 02*). |
| DC | Direct Connect. |
| DCM | Daily Cumulative Meter (DCM) load represent smaller sites that have cumulative meters (less than 500 kW). Cumulative meters do not have time of use measurement. Hourly profile is calculated during the load settlement process. See Benchmark Report for profile classes. |
| DEC | De-Energize Completion. |
| De-energized Site | A connected site that is not currently consuming power. |
| DEF | De-Energize Failure. |
| Delta Usage (kWh) | Budget usage - Actual usage ("0" if no budget value provided). |
| Demand | The rate of consumption over time to reach maximum load. |
| Demand (kVA) Status | Describes the type of Meter Reading. |
| Demand (kVAh) Status | Describes the type of Meter Reading. |
| Demand (kVAr)Status | Describes the type of Meter Reading. |
| Demand (kVArh) Status | Describes the type of Meter Reading. |
| Demand (kW) Status | Describes the type of Meter Reading. |
| Demand Charge | The component of a two-part price for electricity that is based on a customer's highest power demand reached in a specified period, usually a month, regardless of the quantity of energy used e.g., $2.00 per kilowatt per month). The other component of the two-part price is the energy charge. |
| Demand Sales | A producer agrees to make generating capacity available to a buyer when it is called upon or 'demanded'. |
| DER | De-Energize Request. |
| Deregulation | The province of Ontario began deregulation of electricity supply in 2002, but pulled back temporarily due to voter and consumer backlash at the resulting price volatility. The government is still searching for a stable working regulatory framework. See: Ontario electricity policy Natural gas is deregulated in most of the country, with the exception of some Atlantic provinces and some pockets like Vancouver Island. Most of this deregulation happened in the mid 1980s. The current status is a partially regulated structure in which consumers received a capped price for a portion of the publicly owned generation. The remainder of the price is market price based and there are numerous competitive energy contract providers. There is price comparison service operating in these jurisdictions. The province of Alberta has deregulated their electricity provision. Customers are free to choose which company they sign up with, but there are few companies to choose from. The price of electricity has increased substantially for consumers. Higher prices are in part due to the market being too small to attract major competitors to enter it and a tight generation supply condition which is heavily influenced by unplanned generation outages. |
| DFO | Distribution Facility Owner. |
| DG | Distribution Connected Generator, means a generating unit that is interconnected with an electric distribution system. |
| Difference | A differencing settlement system is one that calculates settlement only for those customers who choose a new supplier. |
| DIM | Daily Interval Meter Readings sent every 15 minutes to Retailers and Settlement. |
| Direct Current | (DC) Current that flows continuously in the same direction (as opposed to alternating current). The current supplied from a battery is direct current. |
| Dispatch | A direction from the AESO to a pool participant to cause, permit or alter the exchange of electric energy or ancillary services. |
| Distributed Generation | A generating unit that is interconnected with an electric energy distribution system. |
| Distribution (Electric Distribution System) | The plant, works equipment, systems and services necessary to distribute electric energy in a service area at a voltage of 25,000 volts or less. |
| Distribution Access Service | The service required to transport electric energy by means of an electric distribution system to customers or from distributed generation to the interconnected electric system. |
| DRA | Deposit Reserve Account (also referred to as a Deposit Account or Deposit Reserve) Funds generally used for capital system upgrades and improvements. |
| DSN | De-Select Notification. |
| DSO | Distribution System Operator. A contractor authorized by the wire owner of an electric distribution system to perform certain operating and maintenance functions on behalf of the Wires Owner. |
| DSR | De-Select Request. This is a transaction that is sent by the retailer to the LSA to notify of a site that is going to be de-enrolled. |
| DT | Distribution Tariff. The rates and the terms and conditions that a distribution facility owner charges for providing service to its customers. |
