Which utility serves this customer?
Each Arkansas utility has different net metering rules, rebate programs, and pitch angles. Selecting here loads the right calculator math and proposal template.
Entergy Arkansas
Entergy Arkansas · central, eastern, southern AR (Little Rock metro, Pine Bluff, El Dorado, West Memphis, Forrest City corridor) · ~700K residential + C&I customers · MISO Load Zone 9 · regulated IOU under APSC oversight
Cohort-aware: pre-APSC-successor-docket installs route to qualitative grandfather treatment (battery = backup + future-proofing). Post-docket + new co-installs route to supply-only NM EDG spread. Entergy AR rate (Phase A MEDIUM): ~12¢/kWh blended + ~$11/mo customer charge. Annual Formula Rate Plan (FRP) cadence with historical 1-4%/yr adjustments. MISO LRZ 9 capacity dynamics flow through FAC + fuel-adjustment riders — DISTINCT from PJM 833% framing. No state battery rebate, no state solar tax credit, no utility VPP. Federal ITC expired 12/31/2025.
Lead with: Cohort-aware: pre-docket grandfather = future-proofing + backup pitch; post-docket = standard EDG spread + resilience pitch
SWEPCO Arkansas
Southwestern Electric Power Company (SWEPCO) Arkansas · northwestern + west-central AR (Fort Smith, Texarkana AR side, Hot Springs western fringe) · ~120K AR residential customers · SPP member · regulated IOU under APSC oversight
Cohort-aware: pre-APSC-successor-docket installs route to qualitative grandfather treatment. Post-docket + new co-installs route to supply-only NM EDG spread. SWEPCO AR rate (Phase A MEDIUM): ~13¢/kWh blended + ~$12/mo customer charge. Triennial general rate-case cadence. SPP capacity dynamics — DISTINCT from both MISO (Entergy AR) and PJM. SWEPCO AR ≠ SWEPCO LA / TX — separate AR-specific tariff applies. No state battery rebate, no state solar tax credit, no utility VPP. Federal ITC expired 12/31/2025.
