Definitions
Base energy all kWh charge. Charge applied to all energy (kWh) used by time-of-use customers, no matter when it is used.
Customer charge. An amount paid by a customer for electric service based upon costs incurred for metering, meter reading, billings, etc., exclusive of demand or energy consumption. MGE bills customer charges in dollars per day.
Distribution service. The network of wires and equipment that carries electric energy from the transmission system to the customer's premises. The costs to support, operate and maintain this local delivery system are included here in MGE's rates and are usually priced in cents per kilowatt-hour for energy-only customers and in dollars per kilowatt per day for demand-billed customers.
Electricity service. In MGE's rates, this is the network of generating plants, wires and equipment needed to produce or purchase electricity (generation) and to deliver it to the local distribution system (transmission). Priced in cents per kilowatt-hour for energy-only customers and in dollars per kilowatt per day and in cents per kilowatt-hour for demand-billed customers.
Energy, off-peak. Energy supplied during periods of relatively low system demand as specified by the supplier. For MGE, this is from 9 p.m. to 10 a.m., Monday through Friday; all holidays; and all weekends.
Energy, on-peak. Energy supplied during periods of relatively high system demand as specified by the supplier. For MGE, this is from 10 a.m. to 9 p.m., Monday through Friday, excluding holidays.
Energy, on-peak 1. Energy supplied during periods of relatively high system demand as specified by the supplier. For MGE, this is from 10 a.m. to 1 p.m., Monday through Friday, excluding holidays.
Energy, on-peak 2. Energy supplied during periods of relatively high system demand as specified by the supplier. For MGE, this is from 1 p.m. to 6 p.m., Monday through Friday, excluding holidays.
Energy, on-peak 3. Energy supplied during periods of relatively high system demand as specified by the supplier. For MGE, this is from 6 p.m. to 9 p.m., Monday through Friday, excluding holidays.
Demand, customer maximum 15-minute. The greatest rate at which electrical energy has been used during any period of 15 consecutive minutes in the current or preceding 11 billing months.
Demand, maximum monthly 15-minute. The greatest rate at which electrical energy has been used during any period of 15 consecutive minutes in the billing month.
Demand, maximum on-peak 15-minute. The greatest rate at which electrical energy has been used during any on-peak period of 15 consecutive minutes in the billing month.
Kilowatt-hour (kWh). This is the basic unit of electric energy equal to one kilowatt of power supplied to or taken from an electric circuit steadily for one hour. One kilowatt-hour equals 1,000 watt-hours.
Rates, seasonal. Rates vary depending on the time of year. Charges are generally higher during the summer months when greater demand levels push up costs for generating electricity. All MGE rate classes are seasonal. MGE has summer and winter seasonal rates. Summer rates are effective from June 1 through September 30. Winter rates apply for all other billing periods.
Rates, time-of-use. Prices for electricity that vary depending upon what time of day or night a customer uses it. Time-of-use rates are designed to reflect the different costs an electric company incurs in providing electricity during peak periods when electricity demand is high and off-peak periods when electricity demand is low. Whether customers benefit from time-of-use rates depends on the percentage of total consumption used during on-peak periods. Generally, customers who use less than 35% of their total consumption during on-peak periods may benefit from these rates.
Single-phase service. Service where the facility (e.g., house, office, warehouse, barn) has two energized wires coming into it. Typically serves smaller needs of 120V/240V. Requires less and simpler equipment and infrastructure to support and tends to be less expensive to install and to maintain.
Three-Phase Service. Service where the facility (e.g., manufacturing plant, office building, warehouse, barn) has three energized wires coming into it. Typically serves larger power needs of greater than 120V/240V. Usually required for motors exceeding 10 horsepower or other inductive loads. Requires more and more sophisticated equipment and infrastructure to support and tends to be more expensive to install and maintain.
