Power Supply Chain and Demand in Mississippi
MISO runs most of Mississippi's grid. 4,563 MW of new generation is planned in Mississippi, 2,169 MW of it under construction or built and awaiting operation, against 1,101 MW of planned retirements through 2030. 14 data centers are identified in the state. Residential electricity averaged 15.19¢/kWh in 2026 through July, +9.1% from a year earlier. Unemployment was 3.4% in August 2026, and construction employment is +25.1% against August 2019. The SAVRN trackers hold 1 local moratoria or restrictions for Mississippi across all statuses (1 in force) and 1 named projects on the Delay Watchlist.
What the build-out changed in Mississippi
Mississippi is at the center of the build-out: the demand is here and the construction economy has moved with it. Developers have announced $74.8B of data center capital in Mississippi, 5th among the 31 states with a disclosed figure. Electrical contractor jobs, the trade every data center, substation and plant needs first, grew 33.2% from 2019 to 2025, 10th in the country. Planned generation equals 25% of the power plants Mississippi runs today, one of the steepest build-outs in the country (11th). Households pay part of the cost: residential prices are +9.1% year to date, the 15th fastest increase of 51. Factory employment is the exception: manufacturing jobs are -6.4% against August 2019.

Local moratoria and restrictions (1) appear by county and city in the county-by-county section. Counts include every status in the weekly tracker feeds as of October 5, 2026. The Mississippi Data Center Map page counts only active local pauses and delayed or blocked projects as of its September 2 rebuild, so its figures are lower. The difference is one of definition and date.
