GMO Rate Update Request

The rate update we filed in January of 2018 for our Greater Missouri Operations (GMO) customers has been approved.

GMO Rate Updates

Recently, the Missouri Public Service Commission (MPSC) approved rate updates for KCP&L and Greater Missouri Operations (GMO). This update includes savings related to the 2018 merger with Westar Energy and new lower federal tax laws.

For GMO residential customers, this will result in the following annual base rate decreases starting December 6, 2018:

  • GMO: $24 million decrease (just under $6 a month on your energy bill)

Additionally, we're passing along 100% of savings from the Tax Cut and Jobs Act, decreasing the corporate tax rate from 35% to 21%, which results in the following:

  • GMO: $29.3 million in savings applied as a one-time credit on January 2019 bills

What's new?

This is how we're investing to enhance your customer experience:

  • A new customer information system, so we can ensure improved, consistent and more efficient customer communications where you receive information about energy solutions with ease.
  • Budget- and environmentally-friendly options, so you can better manage your personal energy usage needs and access renewable energy, including Solar Subscription providing the community access to solar energy (no rooftops required). 

The MPSC also approved new rate design changes.

What's rate design, and how's it changing?

Your bill shows different charges, fees and other adjustments that make up the total cost of your energy bill, which you can view here. Rate design is the way we set bill amounts and define charges and fees.
Within our rate update, we streamlined your Customer Charge to $11.47 for all Missouri customers, which is roughly a $1 increase for GMO and $1 decrease for KCP&L. Below are energy charges for common rates:
