Evaluation of Mississippi Power's 2021 Integrated Resource Plan


Synapse assisted Sierra Club with comments on Mississippi Power's 2021 Integrated Resource Plan. These comments identify areas in which Mississippi Power’s IRP failed to advance the goals of protecting ratepayers, providing transparency, and operating a well-planned and efficient electricity system. To address these flaws, Sierra Club and Synapse made the following recommendations:

• Mississippi Power should accelerate the retirement of Plant Daniel, an uneconomic coal plant that the utility currently plans to operate until 2027.

• Mississippi Power should devote more funding to energy efficiency and demand-side management programs that help customers use energy more efficiently - saving money and helping the environment in the long term. Mississippi Power’s commitment to low-income energy efficiency programs pales in comparison to other jurisdictions with comparable high energy burdens and high poverty rates.

• The Commission should revise the IRP rule to require greater transparency and opportunity for public input because utilities will not do so without a stronger mandate. Greater transparency and opportunities for public engagement would strengthen Mississippi’s IRP process and center customers in the process.
