Impact of Utility-Scale Storage on ERCOT Curtailment and Emissions

A paper accepted to IEEE PES GM 2025 (authors Cody Buehner, Sharaf K. Magableh, Oraib Dawaghreh, Caisheng Wang) analyzes how utility-scale energy storage can reduce renewable generation curtailments and CO2 emissions on the ERCOT grid.

• Main analysis: Uses ERCOT planning data and the NREL System Advisor Model (SAM) to model scenarios from 2023–2033, comparing renewable generation curtailment and CO2 emissions with and without utility-scale storage; paper explicitly considers the planned phase-out of fossil fuel plants and integration of new wind/solar projects.
• Publication and data details: Accepted for 2025 IEEE Power & Energy Society General Meeting (PESGM); available on arXiv (arXiv:2502.15958, v3) with DOI links; methodology and scenario comparisons are verifiable from the provided PDF and ERCOT/NREL inputs.
