The Missouri Energy Efficiency Investment Act (MEEIA) cycle 4 regulatory processes for the two largest electric investor-owned utilities (IOUs) in the state have finally reached their conclusions. These dockets have played out slowly over the past two years. Ameren Missouri originally submitted their intent to file MEEIA Cycle 4 programs with the Missouri Public Service Commission (PSC) in October 2022, with Evergy filing in April 2023. After the proceedings, the approved programs for both utilities went into effect on January 1, 2025.
Although this is the fourth full set of programs the electric IOUs have applied for since the passage of MEEIA in 2009 - not including MEEIA cycle 3 extensions – the final MEEIA 4 programs pale in comparison to previous plans. After extensive testimony and negotiations between intervening parties in the dockets, the resulting settlement agreements outline a much smaller scope of programs than originally proposed.
The timelines of both dockets are outlined below.

There were some arguments put forth during the proceedings in the testimony that were not correct. Notably, EE opponents continued to raise the ‘principal-agent problem’ as a reason to curtail EE plans. Opponents stated that contractors are poorly installing or unnecessarily upselling HVAC systems. If that is a problem, the solution should be better regulation and enforcement of high-quality contractor offerings under EE programs to ensure proper work is done and savings are actually achieved. If a building in Missouri could benefit from energy efficiency upgrades – which, as noted in testimony, is highly likely due to the lack of a statewide building code and limited enforcement of local building codes – then the Commission should enable those upgrades to occur by incentivizing EE programs. Giving consumers access to increase the efficiency of their homes and commercial buildings provides an opportunity to reduce their energy bills and improve the livability of these spaces, granting deeper consumer choice and control. Eliminating EE programs does not solve the problem that there may be unscrupulous contractors implementing energy efficiency upgrades in the state. Instead, this may reduce the number of skilled contractors who would be incentivized to do high quality work under stricter requirements of utility administrated EE programs. There are much clearer solutions to this issue, such as requiring accurate equipment sizing using technology like blower door tests or Fault Detection and Diagnostics tools.
Some parties also challenged the perceived duplicative funding for programs enabled through federal legislation like the Inflation Reduction Act (IRA) and Bipartisan Infrastructure Law (BIL). Assuming they are able to continue, IRA programs – such as the Home Energy Rebates – provide limited and temporary funding that will quickly be expensed and only apply to certain measures. To eliminate utility energy efficiency programs rather than allow Missouri consumers to stack incentives and make the most of these historic, one-time investments, would be extremely short sighted. There are multiple solutions to the challenge of attributing savings to co-delivered incentive programs. Northeast Energy Efficiency Partnerships outlined these different attribution models in their report, Expanding the Energy Savings Pie, and many Midwestern states have already established attribution methods that make sense in their respective state environments. We encourage the Commission, Staff and other parties to review the strategies presented in this research and come up with a model that makes sense for Missouri.
Although we are disappointed to see energy efficiency programs being scaled back in Missouri, we are heartened that the Commission ultimately saw value in continuing some EE and demand response (DR) programs in the state, especially at a time when demand for reliable energy is rapidly increasing. As the state continues to see the impacts on the grid of increased electrification measures, generative AI and machine learning, and data centers it would be wise to encourage more efficient energy usage to minimize capacity strain. While neighboring Kansas implements its first set of energy efficiency utility programs, Missouri is disinvesting in the lowest cost resource of the energy system.
However, the future of EE programs in the state is undetermined and we will soon learn more. In part two of this blog, we will dig into the “Statewide MEEIA Feasibility Study” established in the settlement agreements with the major electric IOUs. We will also review the EE program administrator models across the Midwest as Missouri considers a change to how their programs are run.
