Great Plains Energy-Aquila-Black Hills Transaction

QUESTIONS & ANSWERS Update

The following employee questions have been received since the Great Plains Energy-Aquila-Black Hills transaction was announced on February 2, 2007

1. Will the Aquila acquisition affect the current KCP&L rate cases and will the rate cases fund the acquisition cost?

KCP&L’s current cases in Missouri and Kansas will be treated on a stand alone basis by the regulators, with approval of the merger likely taking place about the same time or shortly after our current cases are decided. We operate in a highly regulated environment and must get state regulatory approvals for our rates. The rate increases sought in the 2007 rate cases will cover elements of the Comprehensive Energy Plan going into service this year, along with higher fuel and operating costs. We expect that the synergies and other impacts of the Aquila transaction will be considered in KCP&L and Aquila future rate cases after the transaction closes.

2. At this point, could there be a counter-offer for Aquila ?

A higher offer for Aquila is unlikely, because the pending purchase resulted from a closed auction process in which other utilities and other parties were invited to bid.

We believe KCP&L is best positioned to capture synergies due to our being located adjacent to Aquila’s service territories, and our familiarity with the region, its operation and our proven track record with the Missouri Public Service Commission and Kansas Corporation Commission.

3. How is the Black Hills purchase of Aquila properties different from our purchase?

The Black Hills purchase is a purchase of specific utility assets from Aquila. Great Plains Energy is acquiring Aquila after the Black Hills transaction. When we acquire Aquila, it will primarily be a Missouri electric utility.

4. If the Aquila acquisition is achieved, how will it affect the company’s credit rating?

We have spent time with both Moody’s and S&P in evaluating the credit impacts of the transaction and we anticipate that, after closing, Aquila’s credit rating would be raised to investment grade and that KCP&L and GXP’s ratings would remain investment grade.

5. How long will the transition take once the acquisition is approved and what will happen to the company names?

We believe it will take about a year. The Aquila name will not be used by us after the transaction closes, but Aquila will still exist as a corporate entity, under a new name, to be determined, with its own customers, rate schedules and investment.

6. Will the CEP be updated to include Aquila’s investments, etc?

No, but we will work to integrate Aquila into our existing CEP where possible. Our overall energy plan for 2010-2015 will include both KCP&L and Aquila.

7. As KCP&L’s size grows, are there current plans to change KCP&L’s name?

There are no current plans to change KCP&L’s name. We believe that there is valuable brand equity in the Kansas City Power & Light name.

8. How will Aquila’s customer satisfaction levels, reliability and safety performance be affected by the acquisition?

A key goal of our Strategic Intent is to achieve Tier One status in all operations areas, and that goal will remain unchanged. We will continue to strive for Tier One safety, customer service and reliability as we integrate Aquila’s operations into ours. We also plan to invest capital to help drive toward those goals.

9. How do our IT systems fit with Aquila’s?

We have many common IT systems, including CIS and People Soft; however much work will be required to integrate the IT operations of the companies. Some of this integration will be done when the transaction closes, but systems work will probably continue well into the first year or two post closing. We will work together to meet auditing standards and execute integration effectively.
