KCP&L Files Rate Increase Request with Kansas Corporation Commission

Kansas City Power & Light Company (KCP&L), a subsidiary of Great Plains Energy Incorporated (NYSE: GXP) today filed a rate increase request with the Kansas Corporation Commission (KCC) to increase base rates for electric service in its Kansas service area. The total amount of the request is approximately $55.2 million. This would raise the typical residential customer monthly base bill 11.5%, or approximately $11.08 each month. If approved, the base rate increase is expected to be effective on October 17, 2010.

"Five years ago we engaged the community to develop a plan to improve the environment and provide reliable electricity to fuel our regional economy,” said Michael Chesser, KCP&L Chairman and CEO. "Today we are one step closer to meeting future demand at the lowest reasonable cost and maintaining competitive electric rates for generations to come.”

KCP&L retail electric rates in Kansas are currently more than 22% below the national average¹.

Rate Increase Drivers

This rate increase request reflects the forthcoming completion of KCP&L’s Comprehensive Energy Plan (CEP), which was developed through a highly collaborative process that included community partners, customers, environmental groups, local elected officials and regulatory staff.

KCP&L’s efforts in developing the CEP were recognized by the Edison Electric Institute, which awarded the company in 2007 its highest honor for community involvement and collaboration. The Plan also was endorsed by local labor unions, neighborhood groups, elected officials, community leaders and local economic development agencies and chambers of commerce.

KCP&L’s rate request includes costs related to investments in new, cleaner and high-efficient coal-fired generation, upgrades to the transmission and distribution system to improve reliability and increases in operations and maintenance costs. The cost of fuel and KCP&L’s various customer energy efficiency and affordability programs, which help customers manage their electricity usage, are not part of this rate request and are recovered through a separate cost adjustment mechanism with no profit to the company.

Iatan 2, an 850 Megawatt (MW) coal-fired generation unit located near Weston, Mo., is scheduled to be completed in late summer of 2010. KCP&L owns 54.7 percent (465 MW) of the unit. The Kansas rate increase request includes the portion of the projected total investment in Iatan 2 allocated to Kansas customers. Rates are expected to be further adjusted, up or down, in 2011 to reflect the actual total investment.

KCP&L intends to file a rate request with the Missouri Public Service Commission for its Missouri service area in early 2010, reflecting its Iatan 2 investment and other costs.

Comprehensive Energy Plan

The CEP was created with a number of short- and long-term goals. The plan was designed to allow KCP&L to provide the electricity needed to support the region’s economy in the future; maintain competitive electric rates; continue to deliver reliable service; balance the benefits of renewable energy with the stability of cleaner coal generation; and respond to rapidly evolving environmental laws and regulations with flexible and sustainable solutions.

By the end of the five-year plan, KCP&L will have invested more than $1.6 billion in CEP projects. Key accomplishments include new generating capacity, environmental upgrades to existing facilities, transmission and distribution improvements, and energy efficiency and affordability programs. In addition to Iatan 2, KCP&L completed a 100MW wind generation project in 2006 in Spearville, Kan. The wind project was completed on time and under budget and provides KCP&L customers with a source of clean, renewable energy. The company recently issued requests for proposals to develop up to another 300MW of wind generation.

KCP&L has demonstrated its commitment to providing environmentally responsible energy by making significant environmental investments at the company’s LaCygne 1 and Iatan 1 generation facilities. These environmental upgrades, which were completed in 2007 and 2009, respectively, allowed KCP&L to meet new federal emissions standards before being required to do so and have had a positive impact on the Kansas City region’s air quality.

Ongoing reliability upgrades to KCP&L’s transmission and distribution facilities are aimed at ensuring a continued high level of reliability of major systems and decreasing the number and duration of outages. KCP&L recently received the PA Consulting Group ReliabilityOne™ award for the third consecutive year, recognizing the company as one of the Midwest’s leading utilities in terms of delivering reliable service to its customers.

KCP&L encourages customers to take advantage of the residential and business energy efficiency, affordability and demand response programs that were introduced as part of the CEP. These initiatives allow customers to better manage electricity usage and control their utility costs, therefore reducing the impact of higher rates.

(1) Reflects KCP&L’s share of the projects. KCP&L’s investments are allocated between its Kansas and Missouri customers. The current methodology allocates approximately 46% of such investments to Kansas customers.

(2) Environmental improvements include investments at Iatan 1 and LaCygne 1. Iatan 1 was addressed in KCP&L’s last rate case; however, some costs that were not included in the last rate case will be addressed as part of the current case. Range reflects the most recent publicly released estimate for Iatan 1.

(3) $10.4 million is included in the rate increase request.

(4) Reflects the cost of the programs implemented in Kansas. These costs are not reflected in the current rate case; rather, they are collected through a separate cost adjustment mechanism with no profit to the company.

(5) Range reflects most recent publicly released estimate. These amounts do not include Allowance for Funds Used During Construction (AFUDC) and capitalized property taxes.

(6) Total investment includes most recent publicly released estimate for facilities common to both the Iatan 1 and Iatan 2 units of $235 million.

Customer Programs and Services

In addition to its suite of energy-efficiency programs, KCP&L also introduced its Connections program earlier this year to help customers take greater control of their energy costs during these difficult economic times. The Connections program helps customers by providing information on payment flexibility and assistance programs, energy-efficiency tools and connections to community resources. The campaign also connects customers with local weatherization resources that enable low-income families to reduce energy bills by making their homes more energy efficient.

"These are challenging economic times for everyone and we understand a rate increase can add to the financial pressures our customers are experiencing,” said Bill Downey, KCP&L President and COO. "We have been proud to support the Kansas City region for more than 125 years, and our success as a company depends on the strength and the vitality of the communities we serve. We believe we have a responsibility to work with our customers and offer assistance to those who need it most.”
