New Energy Economics is actively working to delay and reduce by half Ameren’s proposed 800 MW natural gas project, advocating for its replacement with increased energy efficiency measures and accelerated deployment of renewable energy, including batteries, wind, and solar. Through Ameren’s 2025 IRP update process and related regulatory dockets, New Energy Economics will focus on ensuring the utility accurately accounts for gas price risks, improves its clean energy procurement process, and incorporates more renewable energy, particularly from wind resources in neighboring states.
Additionally, New Energy Economics will collaborate with stakeholders to enhance Ameren’s resource modeling with improved All Source Procurement (ISP) of competitive and reliable clean energy options, and advocate for improved customer programs to alleviate increasing energy demand from tech and industrial customers, while also pushing for public accountability on fossil fuel cost-sharing to reduce cost risk to all consumers related to the cost volatility of natural gas that can lead to hirer customer rates.

Ameren Missouri 2023 IRP Joint Filing Resolution with New Energy Economics
Council for New Energy Economics Alleged Deficiencies/Concerns
New Energy Economics Deficiency 1 – Resolved: Ameren does not adequately account for risk in its natural gas price forecasts.
Resolution: Ameren Missouri contended that it has accounted for the risks cited by New Energy Economics. Ameren Missouri will describe how it accounts for the risks cited by New Energy Economics in future annual updates and IRP filings.
New Energy Economics Deficiency 2 – Resolved: Ameren should move towards capacity expansion modeling, which provides greater flexibility and efficacy in evaluating potential resource plans.
Resolution: Ameren Missouri will evaluate EnCompass, PLEXOS and Aurora against the criteria provided in the comments.
Deficiency 3 – Unresolved: Ameren’s elimination of Grain Belt Express from its analysis of candidate resource options constitutes a supply-side deficiency.
New Energy Economics Concern 1 – Resolved: Ameren should pursue aggressive demand-side management strategies.
Resolution: Ameren Missouri has evaluated both MAP and RAP level demand-side management (DSM) resources in its IRP and has a current MEEIA application in front of the Commission to continue its DSM offerings to its customers.
In addition to resolutions from the 2023 IRP, New Energy Economics is engaging in the following:
- Conduct research, analysis, and engage with utilities and stakeholders to ensure Ameren accurately incorporates global and regional gas fuel price risks and addresses the concerns cited by New Energy Economics in the 2025 IRP annual update.
- Collaborate with Energy Futures Group and NRDC to advance Ameren’s capacity expansion and production cost modeling platform. Evaluate EnCompass, PLEXOS, and Aurora against 2024 IRP Update criteria to improve transparency and provide greater flexibility in potential resource plan evaluations.
- Engage with Ameren’s Renewable Energy Acquisition Division to review and recommend improvements to their clean energy procurement process, focusing on advancing competitive procurement for renewable energy.
- Expand collaborative effort with stakeholders to ensure Ameren incorporates western wind and more solar through Grain Belt Express in 2025 IRP Update modeling and the next Triennial IRP.
- Develop and recommend improved large and low-income customer program options.
- Intervene or file comments in upcoming proceedings: 2025 IRP Updates. Rate Case, Energy Efficiency, and CCN for new gas plants.
