  1. Resource Planning or how do we ensure that we have enough capacity and energy to meet member needs ? Stan Selander Senior Resource Strategist

  2. Timeframes • Real time/day ahead (RT/DA) • Year (for MISO Capacity) • Long term (LT)

  3. DA/RT timeframe • Energy only market • But capacity resources “must offer” • Automated forecasting tools, modified by judgment • Load bid into MISO energy market • Generation offered into MISO energy market • MISO dispatches ALL resources necessary to meet aggregate load requirements

  4. GRE’s long-term resource planning • 10 to 30 years into future • System forecast by resource planning • Plan generation to a 50th percentile demand forecast, 50th percentile energy forecast • Resources planned/dispatched to serve GRE load

  5. Long-Range Planning Process New & Existing Resource Characteristics (Capacities, Heat Rates, Emissions, Energy Patterns, Forced & Maintenance Outage Rates, Fixed and Variable Costs, Construction Costs) Externality Values Forecasts Forecast of Residential Consumers Historical Weather Data Financial Assumptions (Discount and Inflation Rates) Fuel Price Forecasts Historical Load Data Long-Range Load Forecast (Econometric Energy & Demand) Complete Spring Long-Range Financial Forecast (LRFF) (Wholesale Power Rates) Complete Fall Capacity Expansion Plan (IRP) Complete Summer Transmission Plans Financial Assumptions (Discount & Inflation, Rates, Margin & Dept Service Coverage, Interest Income) Overhead (Labor, Depreciation, Interest, Taxes & Insurance) MISO Interaction Each rectangle represents a process. Each color represents major inputs into the next process.

  13. MISO Source: MISO July 2009 Monthly Report July 2009 MISO – 50,911 GWh GRE – 1,094 GWh (≈ 2% of MISO)

  14. Conclusions • GRE’s resource planning is based on member forecasts of demand and energy • The MISO market is a short term energy market and a one-year capacity market • GRE’s resource plan is based on long-term requirements to serve members’ needs
