Westar Energy has agreed to delay a request for a rate increase related to nuclear power plant upgrades as part of an agreement approved by a state commission.
The Kansas Corporation Commission approved a plan Tuesday to allow an extra $3.5 million dollars for Westar Energy to make upgrades to the La Cygne power plant.
Westar Energy and Kansas City Power & Light own the plant together and need to make upgrades to comply with federal emissions rules.
Under the KCC agreement, Westar Energy said it wouldn't ask for a rate increase until March. It means new rates based on the costs of operating the plant won't be effective until October 2015.
Kansas City Power & Light will file its rate case in January and work on the basis of estimated costs until then.
