Scope of services: 

  • Work Stream 1 - Project Initiation 
  • Work Stream 2 - Assessment of P2/6 and Identifying Options for Reform 

o WS2.1 Scope and framework for assessing security performance and measures of characteristic network designs 

o WS2.2 Service quality and cost effectiveness of the present network design practises 

o WS2.3 Risk associated with asset replacement, common mode failures and high impact events 

o WS2.4 Impact of Smart Grid technologies on service quality risk profile 

o WS2.5 Assessment of impacts of alternative control and operation strategies on security of supply 

o WS2.6 Loss inclusive design of distribution networks and impact on security of supply 

o WS2.7 Alignment of security of supply standard in distribution networks with other codes and schemes 

o WS2.8 Options for future development of distribution network standard 

                 - Work Stream 3 - P2/6 Options Report 

                 - Work Stream 4 - Stakeholder Engagement Workshops 

                 - Work Stream 5 - Formal Strategy Consultation for P2 

                 - Work Stream 6 - Detailed review and analysis

                 - Work Stream 7 - Final Recommendation

                 - Work Stream 8 - Programme work for Phase 2


The objective is to review the requirements for and function of a planning standard and if appropriate produce an updated version of Engineering Recommendation P2 so the security provided by Network assets together with systems and infrastructure provided by others (as appropriate) can be assessed against agreed standards.
