Connection is DG6 or higher
Cost of de-energisation exceeds €750+VAT
Subject to Directive from CER
For
System automatically reduces DUoS capacity charges
Against
Minimum MIC “seen” by ESBN planners for design

3. LTNA Option 2
DUoS credit to supplier equivalent to MIC reduction in Option 1, MIC remains unchanged subject to
Site is LTNA (no access to de-energise & customer vacated site)
Connection is DG6 or higher
Cost of de-energisation exceeds €750+VAT
For
Supplier gets a credit for reduced DUoS capacity charges

4. LTNA Option 3
Supplier requests de-energisation and cost of work is socialised subject to
Site is LTNA (no access to de-energise & customer vacated site)
Connection is DG6 or higher
Cost of de-energisation exceeds €750+VAT
For
Supplier not liable for cost of de-energising (remains liable for DUoS while site is registered)
Standard market activity with no new processes
Against
Cost is significant with excavation / permanent reinstatement for deenergisation and again for re-energisation.
Difficulty identifying service cables to a vacant site and technically undesirable.

5. Next Steps
Option 2 (DUoS credit equivalent to MIC reduction) is the ESBN preferred option however certain issues still remain to be finalised.
In order to quantify what impact the proposal will have on costs we will require details from suppliers on the connections that qualify (include MPRN, DUoS Group and current MIC).
When these steps are complete a final proposal will be submitted to CER for decision.
