Reliable, Responsible & Economical

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.

New Era at Riverton

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.

Higher Efficiency Controls Fuel Costs

Recaptured exhaust heat boosts output by 100 MWs or 67% Replaces 1950's era coal units
In service May 1, 2016 Cost - $168 million
What is combined cycle?
Refers to a steam turbine running in combination with a turbine fueled by natural gas. The steam turbine is powered by the exhaust heat of the gas unit.
The Riverton 12 Combined Cycle Unit began commercial operation on May 1, 2016. Continuing a tradition of innovative and economical power generation at Riverton dating back to 1905.
Anticipated emission reductions up to
NOx 95%
SO2 95%
CO2 60% - 70%

Asbury Project Management Holds Down Rate Impact

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.

Anticipated emission reductions up to
SO2 95%
Mercury 85%
Particulate Matter 99%

Project Financing and Rates

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.

Electricity is Still a Good Value

Despite the major environmental projects undertaken in the last several years, electricity remains a good value. Consider all of the ways electricity makes your life better – there is no other product or service that you rely on as much. For less than $5 you can power your entire home for a day. Compare electricity to the cost of a mobile phone plan, satellite television or the price of one fast food meal and the value of electricity shines.

Clean Power Plan

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.

Our work to employ a diversified energy mix reduces the risk of price spikes and reliability concerns that come with overreliance on any one energy resource, particularly intermittent resources. Our focus remains on least-cost options for our customers. We secured contracts for wind energy well ahead of renewable mandates, because it was cost-effective for our customers. In 2014, our purchased power agreements with two Kansas wind projects accounted for 18% of the energy we delivered to the electrical grid.
