Due to the low utilization (capacity factor), the gap was calculated on a MW (fixed) cost basis.

  11. Recent Trends in North American Database2005 - 2007 • Maintenance Index / MWh – Up 10.5 % • Overhaul Index / MWh – Up 16.2% • Shift to more planned overhaul spending • Equivalent Unavailability Factor – Virtually unchanged • Planned Unavailability – Up 1.3 % • Shift in unavailable time from forced to planned • Result • Unplanned Unavailability – Down 2.6% • Unplanned Commercial Unavailability Index - Down 8.5% • Increased maintenance spending in overhauls is reducing market losses

  12. Equivalent Risk Analysis • Solomon’s graphical method for comparison of maintenance risk between plants and major components within plants

  17. Equivalent Generation ComplexityTM(EGCTM)

  18. Methods of Normalization • Historical methods • MW – fixed cost basis • MWH – variable cost basis • GJ variable cost basis (for cogeneration facilities) • Operating hours • These methods do not consider both fixed and variable costs • Solomon’s method – Equivalent Generation Complexity • Predicts total cash less fuel; considering both fixed and variable costs • Derived from our database • Puts various generation technologies, fuels, and utilizations on same spending curve
