agenda
Agenda
  • Assumptions
  • SO – TO Code
  • Grid Code
  • Connection and Use of System Code
  • Process/timescales for change
  • Only an initial view at this stage
  • GB SQSS debate heavily influences changes required
  • Are current arrangements appropriate offshore?
assumptions
Assumptions
  • ‘Offshore Users’ have equitable treatment as ‘Onshore Users’
  • Each offshore network has single point of connection to onshore network
  • Offshore TOs may be nested
  • Offshore networks may connect to onshore transmission or DNOs
  • Offshore transmission will only be AC
  • Must accommodate one or many new TOs
  • Transitional arrangements may be required prior to enduring regime being implemented
  • Any regime developed must be adaptable for the future
so to code 1
SO-TO Code (1)
  • Section B - Governance
    • Practicalities of extending beyond 3 TOs
  • Section C - Transmission Services
    • Switching Arrangements - TO acts under instruction from GBSO
    • DNO interaction e.g. outage co-ordination
    • Interaction between offshore TOs
  • Section D - Planning Co-ordination
    • Is onshore model applicable offshore?
so to code 2
SO-TO Code (2)
  • Section E – Charging
    • Charging Statement for each TO
  • Section F – Communications and Data
    • Are confidentiality provisions in STC suitable?
  • STC Procedures
    • Full review of existing STCPs required
    • Requirement for new ‘Offshore STCPs?’
grid code
Grid Code
  • May require further, additional, regional differences
  • Planning processes
    • Dealing with potential DNO interfaces
  • Connection Conditions
    • Driven by GB SQSS debate
    • Review connection conditions for offshore
  • Operating Codes
    • Safety rules differ for different TO areas
  • General Conditions
    • Constitution of Grid Code Review Panel
connection and use of system code
Connection and Use of System Code
  • Access
    • Allocation of access
    • Compensation for loss of access
  • Exporting GSPs
    • Current issue could be exacerbated via DNO connection
  • Transmission Charging
    • CUSC/Charging statements work hand in hand
    • Same as GB regime?
  • Bilateral Agreements
    • Are existing onshore pro-formas appropriate?
process for change options
Process for change - options
  • Use normal governance arrangements for codes – Authority decision
  • Ofgem/DTI consult – changes designated by Secretary of State
  • Issues to consider:
    • Timescales
    • Complexity and scope of change
    • Interactions between codes (cross-governance)
    • Flexibility
    • Ensuring all interested parties are included
    • Utilisation of existing industry expertise
    • Co-ordination with ongoing GB Code change processes
    • OTEG liaison with industry panels
timescales
Timescales
