2009 Scenario Reliability Assessment - NERC

Scenario Letter(ii) Biomass (wood, wood waste, municipal solid waste, landfill gas,ethanol, and other biomass). 122 .(iii)Carbon Capture and Sequestration(iv) Conventional resources (e.g. coal, gas, nuclear, etc.).ii. Compare the Scenario Case and Reference Case generation mix for eachseasonal peak over the ten-year time frame.b) For Planned and Proposed capacity resources, what process is used to select resourcesto be included for reliability analysis/capacity margin calculations (i.e. forwardcapacity markets, obligation to serve activities, low certainty classes of resourcesunder consideration, etc.)? Compare and discuss the differences between thisScenario Case and the Reference Case submittal.3. Capacity Transactions on Peaka) Purchases on Peaki) Identify and quantify any purchases from other Regions and also those purchasesbetween subregions that affect subregional capacity margins. Discuss how theydiffer from the Reference Case submittal. Categorize them as:i. Firm — contract signed.ii. Non-Firm — contract signed.iii. Expected — no contract executed, but in negotiation, projected, or other.iv. Provisional — transactions under study, but negotiations have not begun.b) Sales on Peaki) Identify and quantify any sales to other Regions and also those sales betweensubregions that affect subregional capacity margins. Discuss any differences tothe Reference Case. Categorize them as:i. Firm — contract signed.ii. Non-Firm — contract signed.iii. Expected — no contract executed, but in negotiation, projected, or other.iv. Provisional — transactions under study, but negotiations have not begun.c) Compare the reliance on outside assistance/external resources (clarify whether it isexternal to balancing area(s) or the Region) that the Regions/subregions requires foremergency imports and reserve sharing to the Reference Case submittal.4. Transmissionb) Describe any new bulk power system transmission needed to be in-service o supportthe Scenario Case, compared to the Reference Case.c) Provide a table, sorted by subregion, of significant transmission additions required tosupport bulk power reliability under this Scenario Case:Transmission Project NameVoltage(kV)Length(Miles)InserviceDate(s)Description/Status122 Biomass: Organic nonfossil material of biological origin constituting a renewable energy source.Page 1862009 Long-Term Reliability Assessment
