Generation Resource Planning in an Integrated Market• Traditional planning concepts
• Base Load
• Intermediate (Cycling) Resources
• Peaking Resources
• Changes in todays integrated market• Huge market penetration by intermittent resources that cannot be dispatched
• Wind today – tomorrow solar
• Low natural gas prices
• Pressure on traditional baseload coal and nuclear units
• Does dispatchability have additional value in today’s market?

Traditional Planning
• Baseload – around 40% to 50% of peak load• Typically the lowest cost of energy units• Coal or Nuclear are prime examples• Hydro would be a good example in some parts of the country but here it is
usually reserved for peaking schedule due to limited availability
• Peaking – around 20% of peak load• Usually highest cost of energy units (except hydro)• Combustion turbines, internal combustion engines• Hydro due to limited schedule
• Intermediate – around 30% to 40% peak load• Normally moderately priced energy – often efficient gas fired units• Could also be older coal units – though these are difficult to dispatch and
follow load

Recent Market Observations
• Influence of nondispatchable wind resources in the SPP Integrated Market affected the value of baseload resources
• Low natural gas prices tended to favor low cost gas units• This is particularly true if they can readily cycle on and off

Variable Costs of KPP Capacity Resources
• Variable Costs are Costs that differ depending on usage• Fuel costs• Water costs• Pollution control additives
• Scrubber limestone, etc• Ammonia for Selective Catalytic Recombiners (SCRs)
• KPP Resources are sold into the SPP IM• Revenue is generated from these sales• Energy sales revenue is compared to Variable costs
• Remember these resources also provide required capacity
• Thirteen month cost comparison

Observations
• The value of a diversified portfolio is even more evident when conditions change• Such as high wind and low natural gas prices
• Note: Wind and coal resources will be valuable with high natural gas prices
• In addition to other types of diversification the ability of resources to dispatch, cycle and follow market prices is more valuable today than in the past• You should consider this in addition to diversification among energy
resources, baseload, intermediate and peaking
