Energy Resource Plan


On August 2, 2012, IPL announced its long-term energy resources strategy. The strategy is a multi-billion dollar plan that balances the company’s supply of energy resources, provides safe and reliable service and maintains competitive costs for the benefit of our customers. There are a number of parts to the overall strategy, which includes plans to:

• Renew the Duane Arnold Energy Center (DAEC) nuclear Purchase Power Agreement (PPA)
• Retrofit larger, existing coal-fired generating stations to reduce emissions and increase efficiency
• Retire older and less efficient coal-fired generating stations
• Construct a combined-cycle, natural gas-fired Marshalltown Generating Station
• Continue commitment to renewable resources and energy efficiency.

Renewal of the DAEC nuclear PPA
On August 7, 2012, IPL submitted a filing to the IUB seeking approval of the company’s proposed DAEC PPA with NextEra. The proposed PPA would take effect in February 2014 which is when the current DAEC PPA expires. Under the proposed DAEC PPA, IPL will purchase 431 megawatts of energy and capacity from NextEra through February 2025.
The IUB issued its oral decision on January 23, 2013.

Marshalltown Generating Station
IPL expects to file for regulatory approvals for plans related to the construction of an approximately 600 megawatt, combined-cycle natural gas-fired generating station in Marshalltown, Iowa. The cost for the new facility is projected to be $700 million.

The company expects to receive the appropriate regulatory decisions by the end of 2014. If approved, IPL expects construction to begin after approvals are received, with an anticipated in-service date of 2017.

The company’s evaluation process of power supply options led to a combined solution of purchasing power from DAEC and construction of a new natural gas-fired facility as the best way to meet the long-term needs of our customers in Iowa and Minnesota, while maintaining a reasonable cost for the power. We expect the current and long-term forecast for a strong natural gas supply to benefit customers.
