  9. Regulatory Asset Base & Valuation David Dawson ERC’s Regulatory Expert

  10. Optimization RAB • ERC checked on-going projects against RAB and did not identify any overlap in claim of value • Otherwise, ERC has relied on SKM et. al optimization of the RAB • DD adjusts for: • Windfall • Connection assets • Sub-transmission assets via disposals

  11. RAB - Windfall • s.4.8.1 of TWRG indicates that asset lives may differ from those used for financial reporting • s.4.8.3 of TWRG indicates the ERC is interested in treatment of windfall gains and losses • These could arise from valuation or a change in asset lives

  12. RAB – Windfall Potential

  13. RAB – Windfall Treatment • For DD only history known from 1996 appraisal using 30y uniform life

  14. RAB – Windfall DD Review • Windfall applicable for ODRC and appraisal to the extent asset lives now recommended to differ from 30y • DD only looks at substations, lines, interconnectors, meters & communications • Other assets (appraisal) not yet examined in detail

  15. RAB – Subtran & Connection (a) • Focus for DD on plant & equipment • Use SKM data on T/ST & N/C definitions • Resultant outcome is four groupings • Transmission divided by network & connection • Sub-transmission divided by network & connection

  16. RAB – Subtran & Connection (b) • Summary for substations

  17. RAB – Subtran & Connection (c) • Summary % for substations
