AAHEDC - Assistance for Areas with High Electricity Distribution Costs Scheme Tariffs

The Assistance for Areas with High Electricity Distribution Costs Scheme was introduced in the Energy Act 2004. The intention of the Scheme is to reduce the costs to consumers of the distribution of electricity in certain areas. Currently the only Specified Area is the North of Scotland. National Grid therefore recovers an Assistance Amount through the Scheme, which is passed to the Relevant Distributor in the Specified Area, Scottish Hydro Electric Power Distribution Ltd. This enables distribution charges to be reduced.

Distribution Connection and Use of System Agreement (DCUSA)

The Distribution Connection and Use of System Agreement (DCUSA) was established as a multi-party contract between the licensed electricity distributors, suppliers and generators of Great Britain. It is concerned with the use of the electricity distribution systems to transport electricity to or from connections to them.  It is a requirement that all licensed electricity distributors and suppliers become parties to the DCUSA.

Feed-in Tariffs

The Feed-in Tariffs (FITs) scheme was introduced on 1 April 2010, under powers in the Energy Act 2008. Through the use of FITs, DECC hopes to encourage deployment of additional small-scale (less than 5MW) low-carbon electricity generation, particularly by organisations, businesses, communities and individuals that have not traditionally engaged in the electricity market.

This will allow many people to invest in small-scale low-carbon electricity, in return for a guaranteed payment from an electricity supplier of their choice for the electricity they generate and use as well as a guaranteed payment for unused surplus electricity they export back to the grid.

FITs work alongside the Renewables Obligation (RO) – which is currently the primary mechanism to support deployment of large-scale renewable electricity generation – and the Renewable Heat Incentive (RHI) which supports generation of heat from renewable sources at all scales.

Line Loss Factors

As energy travels from the point of production to the end user, some of it is ‘lost’ on the system. Under the BSC arrangements there are two ways in which these losses are accounted for:
•Losses on the low voltage Distribution Networks are allocated through the use of Line Loss Factors (LLFs).
•Losses on the high voltage Transmission System are allocated across BSC Parties through the use of Transmission Loss Multipliers (TLMs).

Line Loss Factors (LLFs) are multipliers which are used to scale energy consumed or generated in order to account for losses on the UK’s Distribution Networks. There are two types of Line Loss Factor: Central Volume Allocation (CVA) LLFs and Supplier Volume Allocation (SVA) LLFs.


All LLF data is published on the ELEXON Portal:

 Renewables Obligation Scheme

The RO places a mandatory requirement on licensed UK electricity suppliers to source a specified and annually increasing proportion of electricity they supply to customers from eligible renewable sources or pay a penalty. The scheme is administered by Ofgem who issue Renewables Obligation Certificates (ROCs) to electricity generators in relation to the amount of eligible renewable electricity they generate. Generators sell their ROCs to suppliers or traders which allows them to receive a premium in addition to the wholesale electricity price.

Suppliers present ROCs to Ofgem to demonstrate their compliance with the obligation. Where they do not present sufficient ROCs, suppliers have to pay a penalty known as the buy-out price. This is set at £40.71 per ROC for 2012/13 (linked to RPI). The money collected by Ofgem in the buy-out fund is recycled on a pro-rata basis to suppliers who presented ROCs. Suppliers that do not present ROCs pay into the buy-out fund at the buy-out price, but do not receive any portion of the recycled fund.

RCRC Charges

Residual Cashflow Reallocation Cashflow (RCRC) is to cover balancing costs in the last 15 minutes before gate closure. The charge is for each half-hour, and may be positive or negative. For all Settlement Periods, the Total Residual Cashflow (TRC) is calculated as being the sum of all energy imbalance charges across all parties and accounts. This value represents the total amount of money to be redistributed (or collected) via the Residual Cashflow Reallocation Cashflow (RCRC). Each party will be allocated a Residual Cashflow Reallocation Proportion (RCRP) of the TRC for both of its accounts (Production and Consumption). AKA Beer Fund.

RCRC information can be found at: https://www.elexon.co.uk/documents/training-guidance/bsc-guidance-notes/residual-cashflow-reallocation-cashflow-rcrc/

•Losses on the low voltage Distribution Networks are allocated through the use of Line Loss Factors (LLFs).
•Losses on the high voltage Transmission System are allocated across BSC Parties through the use of Transmission Loss Multipliers (TLMs).

Under the BSC arrangements Transmission Loss Multipliers (TLMs) are applied to BM Unit Metered Volumes as a means of scaling to account for losses on the Transmission System. The formulas for calculating Transmission Loss Multipliers are set out in BSC Section T, Paragraph 2.3.1.

Historic Transmission Loss Multipliers data can be downloaded from the ELEXON Portal, as well as historic Estimated Transmission Loss Adjustment (ETLMOs), which are parameters set for the purposes of BMRS reporting.
