Economy 10
Encyclopedia
Economy 10 is the name of a tariff provided by United Kingdom
electricity
suppliers created in 2004. Similar to the Economy 7
this is designed to be used with high thermal mass heating such as storage heater
s, underfloor heating
, and is also used with electrical boilers driving radiators or water-based heat stores.
In contrast to Economy 7, which only provides off-peak electricity during night time hours, Economy 10 tariffs provide 10 hours of off peak heating split between night, afternoon and evening. The advantage of this scheme is that by matching the storage periods better to the times when heat is required, less heat needs to be stored during the day, when there may be no demand for heating. The afternoon and evening periods also provide a top-up to heating systems at off-peak prices.
Off-peak electricity costs can be half of peak prices, but many Economy 10 tariffs levy an increased standing daily charge.
The structure of the 10 off peak hours is as follows:
3 hours in the afternoon (1pm - 4pm)
2 hours in the evening (8pm - 10pm)
5 hours overnight (Midnight - 5am)
Times vary across suppliers, and are switched automatically. It's common for the switching times to be locked to either GMT or BST when the meter is installed. Some metering systems use a radio teleswitch
controlled by the supplier to vary switching times, and effect the Daylight Saving Time switchover twice a year.
Economy 10 thus requires a special multi-tariff meter, different from an Economy 7 meter.
