Plant Data

Ownership

The plant was owned by Kansas City Power & Light (KCP&L). In 2016, KCP&L and Westar announced merger plans,[7] but this proposed merger was rejected by Kansas Corporation Commission utility regulators as unfavorable to Kansas consumers.[8] A new merger plan with KCP&L was announced in 2017.[9] As of May 24, 2018, this merger has been approved by both the Missouri Public Service Commission and the Kansas Corporation Commission, with the combined company to be named Evergy.[10] KCP&L and Westar became the two operating companies of Evergy.

On October 7, 2019, the Westar and KCP&L brands were retired, and the company adopted the Evergy brand across its entire service territory.[11]

Iatan 2

History

In March 2007, KCP&L, the Sierra Club, and the Concerned Citizens of Platte County (CCPC) agreed to a legally binding contract that will run through 2015 and reduce emissions for the Kansas City-based utility, thus resolving four appeals and a six year dispute with the Sierra Club. KCP&L agreed to reduce overall carbon dioxide emissions by 20 percent by 2020 through legislative and regulatory changes that are yet to be determined, and also agreed to offset all greenhouse gas emissions at its Iatan 2 unit. This will be accomplished by adding 400 MW of wind power, and programs that will save 300 MW of energy demand. The measures will be initiated by 2010 and fully implemented by 2012.[12]

In May 2008, KCP&L released new cost estimates for plant, raising the cost 15 percent to almost $2 billion, and indicated it may increase the estimate again after the engineering analysis is complete. KCP&L expects to raise customers' electric rates by over 25 percent to cover costs of the new plant.[13]

The Kansas Electric Power Cooperative (KEPC), which wants to invest $55 million in the plant for a 3.5 percent share, was turned away by the Rural Utilities Service when the agency issued a moratorium on loans for new coal plants in early 2008. However, KEPC received alternate financing from the National Rural Utilities Cooperative Finance Corporation (CFC) at 2 percentage points higher than the original RUS loan.[14]

On January 13, 2010, KCP&L announced that construction of the new plant had fallen behind schedule. The company estimated that the plant could be in service two months later than expected. The delay could also push back a rate increase request filed in Kansas and slated for October 2010, and another to be filed in Missouri and slated for the first quarter of 2011.[15] On December 7, 2010, Governor Jay Nixon dedicated the Iatan 2 plant.[16]

Rate Increase

According to an August 2008 update by the Sierra Club, Platte County School district is concerned that KCP & Light is not paying enough taxes on its Iatan 2 unit. Given the rising costs of the plant construction, the school feels the amount that they are receiving will not be enough to offset the financial difficulties they will face once the new projects are completed.[17]

In April 2011, the Missouri Public Service Commission voted 5-0 to approve Kansas City Power & Light’s (KCP&L) request for a $34.8 million rate increase. KCP&L initially sought an increase of $92.1 million, stating higher than expected running costs of the new Iatan 2 plant as the primary reason for the increase request. Under the new agreement, which will go into effect May 4, 2011, roughly 350,000 customers in Kansas City will see an estimated increase in their monthly bill of $4.85 (5.23%). Starting in June 2011, customers once served by Aquila Inc.’s Missouri Public Service and St. Joseph Light and Power will also pay higher annual rates. This is the fourth rate increase KCP&L has been granted since 2005.[18]

Death and disease attributable to fine particle pollution from Iatan Generating Station

In 2010, Abt Associates issued a study commissioned by the Clean Air Task Force, a nonprofit research and advocacy organization, quantifying the deaths and other health effects attributable to fine particle pollution from coal-fired power plants.[19] Fine particle pollution consists of a complex mixture of soot, heavy metals, sulfur dioxide, and nitrogen oxides. Among these particles, the most dangerous are those less than 2.5 microns in diameter, which are so tiny that they can evade the lung's natural defenses, enter the bloodstream, and be transported to vital organs. Impacts are especially severe among the elderly, children, and those with respiratory disease. The study found that over 13,000 deaths and tens of thousands of cases of chronic bronchitis, acute bronchitis, asthma, congestive heart failure, acute myocardial infarction, dysrhythmia, ischemic heart disease, chronic lung disease, and pneumonia each year are attributable to fine particle pollution from U.S. coal plant emissions. These deaths and illnesses are major examples of coal's external costs, i.e. uncompensated harms inflicted upon the public at large. Low-income and minority populations are disproportionately impacted as well, due to the tendency of companies to avoid locating power plants upwind of affluent communities. To monetize the health impact of fine particle pollution from each coal plant, Abt assigned a value of $7,300,000 to each 2010 mortality, based on a range of government and private studies. Valuations of illnesses ranged from $52 for an asthma episode to $440,000 for a case of chronic bronchitis.[20]

Type of Impact Annual Incidence Valuation
Deaths 9 $63,000,000
Heart attacks 13 $1,400,000
Asthma attacks 150 $8,000
Hospital admissions 6 $150,000
Chronic bronchitis 5 $2,400,000
Asthma ER visits 9 $4,000

Coal Waste

Iatan ranked 94th on list of most polluting power plants in terms of coal waste

In January 2009, Sue Sturgis of the Institute of Southern Studies compiled a list of the 100 most polluting coal plants in the United States in terms of coal combustion waste (CCW) stored in surface impoundments like the one involved in the TVA Kingston Fossil Plant coal ash spill.[21] The data came from the EPA's Toxics Release Inventory (TRI) for 2006, the most recent year available.[22]

Iatan Generating Station ranked number 94 on the list, with 240,245 pounds of coal combustion waste released to surface impoundments in 2006.[21]
