Initial view on changes to Codes
OTEG, 3rd July 2006
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
‘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)
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)
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
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
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
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
