Electricity Market Reform (EMR)
EMR describes the range of measures introduced by the Energy Act 2013 to support future energy supply and security and is made up of four elements:
- Carbon Price Floor which sets a minimum price for carbon in the UK
- Emission Performance Standard which limits the carbon emissions new fossil fuel power stations can emit
- Contracts for Difference which is a support scheme for low-carbon generators (see separate entry)
- Capacity Market which helps to ensure future security of supply (see separate entry)
The cost of implementing EMR plus the cost of paying generators under the Contracts for Difference and Capacity Market schemes is paid for by energy users through their bills

Transmission Network Use of System charge (TNUoS)
Your TNUoS charge may depend on: where you are in Great Britain; when you use the network; how much you consume. Most traditional Half-Hourly metered customers are currently charged on a Triad basis. Non Half-Hourly metered customers are charged based on their profiled consumption between 4-7pm all year round. TNUoS tariffs are published by 31 January and take effect from 1 April each year.
