Metering

My organisation has half-hourly meters, but they are not settled on the half-hourly market. Will it qualify for the CRC?

No, if an organisation has no half-hourly meters settled on the half-hourly market, it does not qualify for full participation in the CRC Energy Efficiency Scheme.

There are four types of meter that can be settled on the half-hourly market. These are:

  • Mandatory half-hourly meters (which are half-hourly meters required to be installed in certain situations)
  • Voluntary half-hourly meters
  • Half-hourly light meters
  • Dynamic pseudo half-hourly meters

For further information concerning meters, please refer to Chapter 4 of the Government Response on the Consultation October 2009.

What is meant by dynamic supply?

Dynamic supply is characterised by the existence of the following elements:

  • A set of equipment fixed to land that performs a common function (for example street lighting).
  • One element of the set of equipment is metered (for example a lamp post).
  • The existing meter point is used as a benchmark to determine the overall supply to the entire set of equipment in a given period.

Therefore, dynamic supply should be considered as pseudo half-hourly meters settled on the half-hourly market when assessing qualification.

In terms of qualification, what happens if an Automatic Meter Reading (AMR) meter was installed during or after 2008?

The qualification year for the introductory phase is the 2008 calendar year. This means that the annual electricity consumption through all half-hourly meters (including AMR) must be considered up to the 31 December 2008 when assessing qualification. Therefore, any electricity supplied through AMR during 2008 will count towards the 6,000MWh qualification criterion.

If an AMR is fitted after 31 December 2008, within an organisation that does not qualify for the introductory phase, qualification will be reassessed for the second phase based on half-hourly meter electricity consumption during the phase 2 qualification year (1 April 2010 to 31 March 2011).

AMR meters installed as sub-meters will not count towards the Early Action Metric. This is because participants are required to report their energy consumption data based on readings from their 'fiscal meters'.

If an organisation has at least one half-hourly meter settled on the half-hourly market, but its electricity consumption is below 6,000MWh, how does the CRC apply?

If, during the qualification period, an organisation had at least one half-hourly meter settled on the half-hourly market, but the total annual electricity consumption through all half-hourly meters is less than 6,000MWh, the organisation had to make an Information Disclosure via the online CRC Registry.

The organisation had to provide a list of all half-hourly meters (HHM) settled on the half-hourly market, and calculate how much electricity they consumed through all HHM (including AMR) during the qualification period (which was the 2008 calendar year for the introductory phase).

If the organisation consumed at least 3,000MWh in the qualification year, it had to disclose its total annual consumption of half-hourly electricity for that year. If it consumed less than 3,000MWh in the qualification year, it had to tick the appropriate box on the online form.

Information disclosure had to take place during the registration period for the introductory phase, which was between 1 April 2010 and 30 September 2010. There will be no information disclosures in future phases of the CRC, so if your electricity consumption is less than 6,000MWh, you will not need to register. 

How is electricity consumed through profile class 1- 4 meters handled within the CRC?

Qualification for the CRC is based on half-hourly electricity consumption during the qualification period. Profile class 1-4 meters are not half-hourly, so the annual electricity use from these meter types will not count towards the 6,000MWh threshold. Note that Automatic Meter Reading (AMR) metering cannot be fitted to these profile of sub-meters, and count towards CRC Energy Efficiency Scheme emissions.

In terms of participating in the scheme, a participant must assess all its energy use through all profile class meters in order to calculate its total footprint emissions. This should cover emissions that may potentially be excluded later.

However, emissions to be included in the CRC Energy Efficiency Scheme each year (and which the participant must purchase allowances for) may consist entirely of energy use from ‘core sources’, which do not include electricity consumed through profile class 1-4 meters.

|f, having included all core sources, less than 90 per cent of its total footprint emissions are regulated by the CRC Energy Efficiency Scheme, European Union Emission Trading System (EU ETS) or Climate Change Agreements (CCAs), the organisation must include some of its residual sources, which may include electricity consumed through profile class meters 1-4.

For further information concerning the ‘90 per cent rule’ and core sources, please refer to section 4.2 of the Government Response on Consultation October 2009.

Will it be compulsory to install meters in unmetered sites?

No. However, to provide an incentive for CRC Energy Efficiency Scheme participants to accurately measure energy use, all estimated energy consumption figures will be subject to a 10 per cent uplift.

Do meters with zero supply, including disconnected (de-energised) meters, need to be considered under the CRC?


Disconnected or ‘de-energised’ meters do not need to be considered as part of a participant’s assessment of CRC qualification, reporting requirements or for scoring in the Automatic Meter Reading (AMR) element of the Early Action Metric. The meter would need to be disconnected before the start of a qualification period and remain disconnected throughout the entire qualification period for consumption through that meter not to be considered towards a participant’s qualification.


However, there is a difference between a meter that has been disconnected or de-energised and a meter that is ‘idle’ (for example, it is connected but has no consumption/supply measured through it).


Idle meters must be considered as part of a participant’s assessment of qualification for any CRC phase. The MPAN numbers or MPRN numbers (Northern Ireland) of idle electricity meters will need to be submitted as part of a participant’s registration for any CRC phase.


Any consumption through previously idle meters that become active after the qualification period will need to be reported in subsequent footprint and annual reports and taken into account when determining a participant’s AMR score in the Early Action Metric.
