Excess Capacity Charges UK: Your DCP 161 Legislation 101
What is DCP 161 legislation?
Under DCP comes the introduction of excess capacity penalties for entities that exceed their agreed capacity level. An organisation will be charged an out of contract rate as soon as they exceed capacity level – this could be up to three times higher than the current rate!
Excess capacity charges UK
The new DCP (Distribution Change Proposal) 161 legislation came into force on 1 April 2018. The introduction of the Office of Gas and Electricity Markets (Ofgem’s) excess capacity tariffs affects the electricity charges of many UK business.
Why the DCP 191 legislation changes?
Under current legislation, organisations that exceed available capacity are not charged any penalties, only for the excess energy used. This means that, until now, users have never been incentivised to actively review their allocated capacity, putting strain on the system.
By charging customers for excess capacity levels, the DNOs (Distribution Network Operators) are able to recover the costs incurred when customers exceed their available capacity. Implementing these excess capacity charges will also help DNOs to better balance the usage of their networks.
What are the proposed excess capacity charges in the UK?
The excess capacity charge rates will vary by voltage and region – in areas with higher demands for capacity the costs are expected to be higher. There is a significant variance in excess capacity charges from region to region – with industry estimates between 49% – 177% for low voltage customers, and 13% – 165% for high voltage sites.
What about my electricity meter?
Companies with high energy consumption are now required to use smart meters (provided by energy suppliers) that provide a half-hourly (HH) measurement. The HH measurement is used to calculate excess capacity charge. Electricity meters that have been or are due to be converted to HH will be settled on the HH market in time for the introduction of DCP 161 legislation.
