Open Access Transmission Tariff
Amendment No. 9
Greg Broeking, Chief Financial Officer
March 7, 2012
Background Information
• A cost-of-service study was performed to:
 Update revenue required to serve the District’s transmission
customers
 Accommodate the significant increase of third-party generation
• Additional study
 An additional review of the cost-of-service was conducted for a
reasonability check
 Other rate options were examined and recommended
 The economic development rate on a MWh basis was proposed to
mitigate the Pancaking Effect

Economic Development Benefits
• The unemployment rate is extremely high in the District’s
service area
 New renewable resources would help create new job
opportunities
• New generation facilities would benefit the ratepayer
 Improving reliability
 Providing additional revenue due to the increase of the throughput
on the District’s transmission system

Overview of Changes
Revisions to IID’s Open Access Transmission Tariff (OATT)
and Generator Interconnection Agreement (GIA):
• Transmission reserve capacity section
 The economic development rate will be on a MWh basis
 Accommodate the significant increase of third-party generation
• Possible reserved capacity requirement(s) to mitigate
financial risk to the District
 Provide a form of support for the reserved capacity that shall be
reasonable for the required service needs
 A review of the customer’s annual usage may be done to adjust
future transmission capacity reservations

Overview of Changes (continued)
 An additional fee may be imposed when the committed minimum
usage is not met
 When not utilized, the reserved capacity will be temporarily
released to the District for potential resell to other customers
• Transmission Rate Credits
 Provided for a period of 25 years or the duration of the Power
Purchase Agreement (PPA), whichever is shorter
