Organisations will be required to participate in the carbon reduction commitment, if their total half hourly metered electricity exceeds 6,000 MWh from 1 January 2008 to 31 December 2008. For the purpose of determining the scheme qualification, the government has proposed that the definition of "half hourly metering" will include all meters that monitor electricity consumption on a half hourly basis. To this end, half hourly metering will include voluntary automatic meters that produce half hourly data. The definition will also include pseudo half hourly meters (irrespective of whether or not they are settled on the non-half hourly market). The above approach has been implemented to address the risk of large organisations choosing to settle half hourly metered electricity on the non-half hourly market, and thereby falling outside the Carbon Reduction Commitment.
