Mississippi commercial electricity averages 9.8¢/kWh — 31% below the national average — served primarily by Entergy Mississippi and Mississippi Power (Southern Company). Despite low base rates, significant savings opportunities exist through LED retrofits, HVAC optimization, and building automation. The state ranks in the top 15 nationally for solar irradiance, and regulatory barriers to commercial solar have been easing since 2023 under Mississippi Public Service Commission policy updates. Mississippi Power's EnergyWise program provides commercial demand response rebates for qualifying customers. Food processing, automotive parts manufacturing, and distribution centers are the dominant commercial energy consumers.
Mississippi businesses: Section 179D deduction expires June 30, 2026 — up to $5.94/sqft in tax deductions on the table.

Utility market structure: Mississippi is a fully regulated utility market. Entergy Mississippi serves the western half of the state, including Jackson, Vicksburg, and the Delta region. Mississippi Power (a Southern Company subsidiary) serves the southern and eastern regions, including Hattiesburg and the Gulf Coast. Singing River Electric Cooperative serves parts of the Gulf Coast and southeastern Mississippi. Rates are set by the Mississippi Public Service Commission (MPSC) — commercial customers cannot shop competitive suppliers.
Commercial solar in Mississippi: Mississippi has some of the highest solar irradiance in the Southeast — comparable to Arizona in peak sun hours. However, net metering policy has historically limited commercial solar adoption. The MPSC updated net metering rules in 2023 to allow larger commercial systems to qualify, making rooftop and ground-mount solar increasingly viable for warehouses, manufacturing facilities, and large retail properties. The federal ITC 48E (30% tax credit) and MACRS accelerated depreciation make solar projects financially attractive even without state-level incentives. Commercial solar payback in Mississippi typically runs 5–9 years before incentives, improving to 4–7 years with full federal incentive stacking.
Mississippi Power EnergyWise program: Mississippi Power operates one of the more accessible demand response programs in the Southeast. The EnergyWise program for commercial and industrial customers provides bill credits for load reduction during peak demand events. Qualifying businesses must have peak demand above a threshold (typically 50 kW or higher) and be willing to curtail load on 30-minute notice during summer peak periods. Credits can offset meaningful amounts of monthly demand charges. Entergy Mississippi also operates demand response programs for large commercial accounts through its Demand Response Rider tariffs.
Key commercial sectors: Mississippi's top commercial energy consumers are food and beverage processing (poultry processing facilities are the single largest category), automotive parts manufacturing (Toyota manufacturing in Blue Springs, Continental Tire), chemical and materials manufacturing along the Gulf Coast, and distribution/logistics centers serving Gulf port operations. These high-energy-intensity facilities have the strongest ROI for efficiency projects including variable frequency drives, industrial LED lighting, process heat recovery, and building automation systems.
Federal incentives available to Mississippi businesses in 2026: Mississippi businesses can access the same federal incentive stack as all US commercial property owners: (1) Section 179D energy efficiency deduction — up to $5.94/sqft for qualifying improvements to HVAC, lighting, and building envelope (construction must begin before June 30, 2026); (2) ITC 48E — 30% investment tax credit for commercial solar and battery storage (available through July 4, 2026 at full rate); (3) MACRS 5-year accelerated depreciation on solar equipment plus 40% bonus depreciation in 2026; (4) Section 48C advanced energy property credit for manufacturers upgrading industrial processes. The combination of these federal incentives makes 2026 the peak incentive year for Mississippi commercial energy investments.
The average commercial electricity rate in Mississippi is approximately 9.8¢ per kWh as of 2025–2026, which is 30.6% below national avg. Actual rates vary by utility, rate class, demand charges, and consumption level. Mississippi has a regulated utility market — rates are set by the state public utilities commission.
Mississippi businesses can access a combination of federal and state programs: (1) Federal ITC 48E — 30% tax credit for commercial solar and battery storage, applicable to all Mississippi businesses; (2) 179D commercial buildings deduction — up to $5.94/sqft for qualifying energy efficiency improvements; (3) (4) Utility rebate programs from Entergy Mississippi and other providers.

Based on Mississippi's electricity rate (9.8¢/kWh), climate characteristics, and available incentives, the highest-ROI commercial energy projects are: LED Lighting, HVAC Optimization, Commercial Solar. While base rates are below the national average, utility rebates and federal tax credits (ITC, 179D, MACRS) still drive compelling project economics.
Yes — Mississippi has high solar potential and commercial solar economics are strong in 2026. The federal ITC 48E provides a 30% tax credit, MACRS allows accelerated 5-year depreciation (plus 40% bonus depreciation), and the 179D deduction may stack if the system is part of a broader energy efficiency package. Typical commercial solar payback in Mississippi ranges from 4–9 years depending on project size, financing, and utility rate class.
In Mississippi's regulated utility market, bill reduction strategies include: (1) Demand charge management — reducing peak demand with automation, storage, or process scheduling; (2) Time-of-use optimization — shifting load to off-peak hours; (3) Participation in demand response programs through Entergy Mississippi; (4) Capital projects — solar, LED, HVAC, and building automation that reduce consumption; (5) Rate schedule review — many commercial accounts qualify for lower rate classes with a tariff analysis.
Mississippi Power's EnergyWise program provides bill credits to commercial and industrial customers who agree to reduce electrical load during peak demand events — typically summer afternoons when grid stress is highest. Qualifying businesses must have peak demand above a utility-set threshold (generally 50 kW or higher for commercial accounts) and agree to curtail load within 30 minutes of notification. In exchange, participants receive monthly demand charge credits that can meaningfully reduce annual electricity costs. Entergy Mississippi offers similar demand response opportunities for large commercial accounts through its tariff riders. Contact your utility's commercial accounts representative to assess your facility's demand response potential.
Yes — though the economics require careful modeling. At 9.8¢/kWh, Mississippi's low base rate extends solar payback periods compared to high-rate states. However, two factors make solar viable: (1) Mississippi has among the highest solar irradiance in the Southeast, generating more kWh per panel than most of the country; (2) Federal incentives — 30% ITC 48E tax credit, MACRS 5-year accelerated depreciation with 40% bonus depreciation in 2026 — reduce effective project cost by 50–55% for tax-paying businesses. After incentives, commercial solar payback in Mississippi runs approximately 4–7 years. Poultry processors, cold storage facilities, and manufacturing plants with large, flat roofs and predictable daytime loads typically see the strongest returns.
