For over 100 years, Empire has provided reliable, responsible and economical energy to the four-states region. The energy we provide today is cleaner than ever. Our focus on fuel diversity, efficiency improvements and environmental upgrades ensures we can continue to provide reliable, locally-sourced energy, jobs and other economic benefits for our region well into the future.
The addition of a new “combined cycle” power production process at Riverton is the first large-frame combined cycle unit in the state of Kansas. As part of a plan to comply with new standards set by the Environmental Protection Agency (EPA), Empire has retired two 1950’s era coal units at Riverton. The combined cycle addition replaced the retired coal units. Its high efficiency is helping hold down fuel costs for customers while lowering emissions and protecting the environment.

In 2014 we completed the addition of an Air Quality Control System (AQCS) at our Asbury Power Plant. Like Riverton, this project was driven by EPA mandates, specifically rules on Sulfur Dioxide, Mercury and Particulate Matter. The estimated cost of the AQCS was $112-$130 million. We were able to hold the project to $112 million, which translates into savings of $2 million in terms of the rate impact to customers.

Rates for the Asbury AQCS project have already taken effect for most customers. During the construction phase of large projects like Riverton and Asbury, financing is provided by shareholders and lenders, similar to a homeowner financing a home construction project. Once the project is complete and approved by regulators, the cost will be factored into customer rates to repay lenders and investors. In Missouri, the approval process typically takes 11 months.
Despite the legal challenges, the Clean Power Plan will likely have an impact on future energy generation. Our investment in the Riverton project better positions us to meet future carbon regulations.
