Frequently Asked Questions
ESOS (Energy Savings Opportunity Scheme) is an energy assessment scheme that is mandatory for large organisations in the UK with more than 250 employees, turnover in excess of €50m and an annual balance sheet total of €43m. The Environment Agency is the UK scheme administrator and reporting is required every 4 years, the current deadline being 5th December 2019.
A smart meter is an electronic device that records consumption of electric energy and communicates the information to the electricity supplier for monitoring and billing. Smart meters typically record energy hourly or more frequently, and report at least daily.
A degree day is a measure of heating or cooling used to determine the heating requirements of buildings, representing a fall of one degree below a specified average outdoor temperature (usually 18°C or 65°F) for one day.
Any meter used for billing purposes must be of an approved pattern or type. It’s important to use Ofgem\MID approved meters. Compliant with current legislation and governed by the 1989 Electricity Act, only meters that meet the Ofgem\MID standards can be used.
CT - Current Transformers allow large loads to be measured by reducing the level of current passing through the meter to a manageable level. An example CT Ratio is 200/5 that means that for every 200 amps of current received, only 5 amps are passed the meter.
Half-hourly data is a record of the energy used in every half-hour period of every day. Half-hourly data is a common form of interval energy data. It is collected by a half-hourly meter, which, every half-hour, records how much energy was used in the previous half-hour.
Definitions & Acronyms
AMR – Automatic Meter Reading - AMR is the term given to a metering system that provides meter readings remotely.
