In 2018, the Mississippi Public Service Commission issued an order establishing a docket to consider development of an Integrated Resource Planning (IRP) process for regulated utilities in the state. GridLab supported 25×25 in development of comments to support the adoption of an IRP rule, highlighting best practices in planning processes from across the region and country. Following these comments, the Commission subsequently requested comments evaluating the proposed IRP rule submitted by Entergy. GridLab again supported the development of comments outlining omissions and flaws from the proposed Entergy IRP rule. GridLab retained consultants from Strategen to assist in developing comments.
