Presentation Transcript

  1. Initial view on changes to Codes OTEG, 3rd July 2006

  2. 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?

  3. 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

  4. 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?

  5. 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?’

  6. 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

  7. 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?

  8. 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

  9. Timescales • June 06 Initial view on code changes • Sept 06 Follow on from GBSQSS group • Scope required changes further • Q1 07 Specific identification of required changes • Q2 07 Industry consultation • Q2/3 07 Refinement of changes • Finalise details of legal drafting • Q3/4 07 Final consultation • Mid 08 Go-Live for offshore regime
