Rate Updates

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

For Missouri residential customers, this resulted in the following annual base rate decreases starting December 6, 2018:

  • $21.1 million decrease (over $2 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:

  • $38.7 million in savings used to offset regulatory costs (which means a one-time credit won't appear, but instead, you'll benefit from reduced costs over time)

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 decrease for KCP&L Missouri. Below are energy charges for common rates:
