Mississippi Solar Export Credits: What Entergy's DG Adder Does and Does Not Cover
Entergy Mississippi's export calculation includes separate components. The income-qualified adder is not automatically available to every solar household.
A Mississippi solar estimate can go wrong if it assumes that electricity sent to the grid cancels purchased electricity at the same price. For Entergy Mississippi customers, the current tariff assigns exports a separate dollar credit.
This article uses Entergy Mississippi's NEM-2 schedule. It does not apply Entergy's figures to Mississippi Power, cooperatives, municipal providers or TVA-served customers. Mississippi Power publishes its own renewable-energy programs and customer arrangements.
The distinction is important when a salesperson describes a “Mississippi net-metering rate” without naming the utility.
Read the export components separately
Entergy Mississippi's current NEM-2 Attachment A lists, effective with the first February 2026 billing cycle, 3.6 cents per kWh for avoided wholesale power and 2.5 cents for distributed-generation value. The resulting export credit is 6.1 cents per kWh, or 8.1 cents with the qualifying 2-cent income-based adder. Customers opting out of the DG-value component receive different treatment.
Those are dated tariff figures, not a guaranteed price for the life of a loan. A proposal should state which components it includes and why the household qualifies.
As a simple illustration, 500 exported kWh at 6.1 cents produces $30.50 of calculated export value. At 8.1 cents it produces $40.50. This arithmetic does not describe the whole bill, determine eligibility or include every charge. It shows why assuming the higher credit without confirming qualification can distort a savings estimate.
Imports and exports are different records
NEM-2 bills imported electricity under the applicable retail schedule and values metered exports separately. Excess-energy credits cannot reduce fixed monthly customer charges or minimum-bill provisions. The DG-value component also carries a renewable-energy-credit transfer condition; customers may opt out and retain those attributes.
Ask for a model that separates electricity consumed directly in the house from electricity exported. If the proposal simply multiplies annual panel production by a retail rate, ask how it accounts for the actual export arrangement.
That question also matters when someone proposes a battery or additional panels after savings disappoint. A change in the amount exported can alter the calculation, but it does not prove that another purchase is financially worthwhile. Request a complete comparison including the added cost and financing.
Confirm an adder instead of assuming it
The tariff's residential income-based adder requires certification, including household income at or below 225% of the federal poverty level, primary-residence conditions and utility verification. A seller's estimate is not the certification.
Ask which application establishes eligibility, whether it has been accepted and where the resulting credit appears on the bill. Keep the answer with your agreement. Do not confuse an ongoing export adder with a separate installation incentive, and do not count an incentive as received merely because it appears in a sales proposal.
Keep the utility and financing problems distinct
Collect the import and export readings, production reports and the original savings calculation for matching billing periods. Then compare the assumed credit with the account's actual credit. Separately list the solar payment and any promised escalation or payment change in the agreement.
A household can have correctly calculated utility credits and still face an unaffordable combined payment. It can also have a billing error that needs utility review without proving that the equipment or financing agreement is defective. Identify the issue before accepting a proposed fix.
Solar Exit's utility-billing review and contract review can help organize the records. Preserve the original proposal and any written explanation of the adder so a later correction does not erase the original representation.
General consumer information, not legal, tax, insurance or electrical advice. No incentive, contract remedy or savings outcome is guaranteed.
