Annexe 2

Annexe 2 is part of each DNO's annual Charging Statement that contains the site-specific tariffs for EDCM (Extra High Voltage) connections. While Annexe 1 contains standard CDCM tariffs that apply to categories of customers, Annexe 2 lists individual tariffs for each EHV site.

What Annexe 2 contains:

• Import capacity charges (p/kVA/day)
• Export capacity charges (p/kVA/day)
• Exceeded capacity rates
• Super Red unit rates (p/kWh)
• Fixed charges (p/MPAN/day)
• Reactive power charges (p/kVArh)

Site identification: Each site is listed by MPAN or site reference, with its own unique set of charges calculated using the DNO's network model. This means two EHV sites in the same DNO region can have completely different tariffs based on their location and network impact.

Publication cycle: Like all DUoS tariffs, Annexe 2 is updated annually with new rates effective from 1 April each charging year. DNOs publish draft rates in autumn for consultation before finalising.

Why site-specific: Unlike lower voltage connections where costs can be averaged across similar customers, EHV sites have such individual network characteristics that bespoke pricing is more cost-reflective.
