OFGEM is introducing new legislation from April 2018 which will impose penalty rates on half hourly supplies that exceed their Authorised Supply Capacity (ASC).

Currently any site which exceeds its capacity is charged the same rate as their authorised capacity.

Capacity used above the authorised level will be charged at penalty rates which is up to three times higher than the standard rate per kVA. The rates vary depending on distribution region and voltage type and is expected to be higher in areas where demand is high .

The new legislation, known as DCP 161, will also impact on supplies that have been or will be converted to half hourly as a result of P272 migration (profile class 05-08 Non half hourly supplies).

It is important that available capacity and maximum demand levels are monitored to ensure supplies stay within authorised available capacity levels.

Apollo Energy's Consultants can help clients apply to the networks to increase authorised capacity levels.
