| PBR | Performance Based Rates - a concept of providing incentives to improve productivity while sharing the gains between customers and shareholders. |
| PDI | Point-of-Distribution-Interchange. A conceptual point of interchange between distribution systems areas. |
| PDS | Point-of-Distribution-Supply. A conceptual point of supply onto a distribution system. A PDS is the point at which energy is deemed to be supplied on the distribution system. This is the interconnection point between a distributed generator and a distribution system. |
| Peak Demand | The maximum load during a specified period of time. |
| Peak Load | Peak load is the maximum hourly consumption in a day (i.e. the maximum load consumed or produced by a unit or group of units in a stated period of time). |
| Percent(%) of Total Load | Percent (%) of Total Load is the fraction of the total corporate monthly consumption. |
| PFAM | The Post-Final Settlement Adjustment mechanism (PFAM) is a process for correcting errors in settlement results after the financially-binding Final settlement. |
| PFAM Indicator | The PFAM indicator will show a -1 if the RISS number is higher than the WSD number, it will show 0 if the RISS number is equal to the WSD number and will show +1 if the RISS number is lower than the WSD number. |
| PFEC | The Pre-Final Error Correction (PFEC) is a process for correcting errors in settlement results before the Final settlement is run. |
| PICA | Public Institutional Consumers of Alberta. |
| PILOT | Payment In Lieu of Income Tax - Payments by municipally-owned or other tax-exempt entities which are exempt from federal and provincial income taxes with the objective of creating a level playing field with investor-owned competitors. |
| POD | Point-of-Delivery. A conceptual point of delivery from the Transmission System. A POD is the point at which energy is deemed to be delivered from the transmission system to the distribution system. A POD is a collection of one or more Administrator's measurement point definition records. |
| POE | Point-of-Exchange. A conceptual point of exchange with non-AIES control areas at transmission voltages. A POE is a collection of PODs and POSs aggregated according to a fixed formula to create a real or virtual point of energy delivery or receipt from outside the transmission system. Refers to BC and Saskatchewan tie lines which supply imports and exports to or from Alberta. |
| POI | Point-of-Interconnection. See Point-of-Exchange (POE). |
| Pool | The Power Pool of Alberta (PPoA). |
| Pool Charge | Allocated power pool spot trading charge and uplift. (uplift for 2001 only) |
| Pool Price | The price for electric energy during a hour, established and reported by the AESO in accordance with the AESO rules, for electric energy exchanged through the Power Pool. |
| Pool Rebate | Allocated Power Pool Rebate (2001 only) |
| Pool Settlement Date & Payment | All financial settlements of the Final Pool Statements occur on the 20th business day following the end of each production period, unless the due date has changed due to prior late payments. Pool participants must arrange for payment of amounts owing, as stated on the Final Pool Statement, to be electronically transferred into the appropriate AESO bank account. All amounts owed to pool participants by the AESO will be transferred on this date as well. |
| POS | Point-of-Supply. The point at which energy is deemed to be supplied to the transmission system. |
| Postage Stamp Transmission Tolls | Transmission rates are averaged so that consumers pay the same transmission rate regardless of their location or distance from generation facilities. |
| Power | The rate at which work is performed or that energy is transferred. Electric power is commonly measured in watts or kilowatts. A power of 746 watts is equivalent to 1 horsepower. |
| Power Factor | The ratio of real power to apparent power delivered in an ac electrical system or load. Its value is always in the range of 0.0 to 1.0 or 0% to 100%. Note: (1.0) indicates that the current is in phase with the voltage and that reactive power is zero. |
| Power Marketer | A company engaged in buying and selling electric energy. |
| Power Pool | Operated by the AESO, it is a market providing the exchange of energy and financial settlement for the exchange of electric energy. |
| Power Pool ID | The Power Pool ID is 3000. |
| Power Purchase Agreement Auction | Auction of Power Purchase Agreements and of derivative contracts associated with Power Purchases Agreements, managed by the Balancing Pool. |
| PPA | Power Purchase Agreement. A legal agreement as described in Regulation for the purposes of selling electric energy from generating plants built prior to 1996 to a buyer of the electric energy and must include a determination of the manner in which excess electric energy produced by the generating unit is to be exchanged by the purchaser of the PPA through the Power Pool for the benefit of the owner of the generating unit. |
| Preliminary Pool Statement | Available on the AESO's Web site on the 5th business day after the end of each production period. Log onto the AESO Web site using a digital certificate to retrieve the Preliminary Pool Statement. A preliminary statement is provided so that pool participants have an opportunity to review the information and contact the AESO if there is a discrepancy prior to the Final Pool Statement being issued. This is not the statement that is paid. |
| Price Cap | A maximum price for electric energy or related services, set by a government or regulatory agency. |
| Price Maker | In the context of an electricity pool, a price making generator will submit a number of bids/offers indicating how much electricity they would be prepared to dispatch at a given price. The system operator (AESO) will place the generators in order of cost to determine which plants will be dispatched. |
| Price Taker | In the context of an electricity pool, a price taking generator will not submit a bid or will submit a bid at zero. This means it will always be dispatched (subject to system constraints) and will receive the pool price. Price taking generators include variable generators with low marginal costs, such as wind. |
| Price Volatility | The rate of change of price over time. |
| Profile Cutoff Date | Date and time specifying the last point at which data is included for profile generation. |
| Profile Segmentation | The method by which sites are divided into profiling classes. |
| Profiling Cap | Also known as threshold, the Profiling Cap is the size level above which a site is required to have interval-metering data. |
| Profiling Class | A group of sites that will be settled using a common load profile. The customer's load profiling class. |
