Senior Researcher Tyler Comings and Researcher Joshua Castigliego co-wrote comments on Evergy's Integrated Resource Plan (IRP) that were filed with the commissions in Kansas and Missouri. AEC's comments focused on Evergy's bias towards choosing new gas replacement, including its assumption that new gas would become carbon-free at no cost. AEC also noted assumptions that were overly optimistic for Evergy's coal units and that the company's consideration of early retirement for some units was too limited.
