Develop Screening Assumptions Delivered Fuel Price Forecast consistent with Electric Resource Plan forecast Environmental Allowance Costs consistent with Electric Resource Plan forecast Spot market capacity and energy prices Resource specific assumptions, including Production Efficiency - Heat rate expressed as the ratio fuel input to electrical output Emissions rates Resource characteristics (e.g., capacity size, fixed costs) June 15, 2009 3
Levelized Cost Analysis Levelized cost is a unitized cost calculated by discounting both an annual stream of costs ( then year dollars, that include the effect of inflation & escalation) and an annual stream of output ( then year output in MWh) using a discount rate representative of LIPA s cost of debt, including inflation Levelized energy ($/MWh) and capacity cost ($/kw-month) of alternatives in 2009$ June 15, 2009 FOR DISCUSSION PURPOSES ONLY 4
Evaluation Technology Results The list of alternative technologies was broken down into five phases and sixteen groups Phases categorize resources by their physical location, whether the resource can be replicated and/or dispatched, and whether resource is new or existing The groupings represent similar types of technologies The 5 phase categories are: Phase 1 New replicable resource located on Long Island (e.g., 7FA generator, 501G generator) Phase 2 - New replicable resource located off Long Island (e.g., Upstate New York Combined Cycle) Phase 3 New limited resource located on Long Island (e.g., Efficiency Long Island ( ELI ), Automated Meter Initiative ( AMI )) Phase 4 Existing resource located on Long Island (e.g., Neptune Cable, Northport) Phase 5 Repowered resource located on Long Island (e.g., Barrett Repower) June 15, 2009 FOR DISCUSSION PURPOSES ONLY 5
