Oncor Electric Delivery — Dallas-Fort Worth metro + East/West Texas (Midland, Odessa, Waco, Tyler) · 4M+ premises serving 13M+ Texans · TDU only (wires and delivery; REP supplies electricity)
TDU only — Oncor owns the wires and sets delivery charges; the customer's REP (Retail Electric Provider) sets the retail rate and the solar export credit. Oncor's "Take a Load Off" Solar PV + Energy Storage rebate (up to $9,000 combined per residential project — the $5,000 solar / $4,000 battery-adder split is UNCONFIRMED against an Oncor primary; program runs Feb–Nov, closes ~Nov 30, 2026) is a SOLAR-INSTALL rebate — it requires installing new solar. It does NOT apply to a battery-only retrofit (the proposal tool's default modeled customer). For a solar+battery sale (where Top Tier installs both), the rebate is real money on the table and lives in the rep guide. REP-dependent NEM: Tesla Electric (Fixed plan, Powerwall) and Octopus's Intelligent Octopus for Home (Enphase / SolarEdge / SolarEdge Nexis) are the representative solar-friendly plans we model today.

CenterPoint Energy — Greater Houston metro + 8-county electric footprint (Harris, Brazoria, Chambers, Fort Bend, Galveston, Liberty, Montgomery, Waller) · ~2.8M electric customers · TDU only (wires and delivery; REP supplies electricity)
TDU only — CenterPoint owns the wires and sets delivery charges; the customer's REP (Retail Electric Provider) sets the retail rate and the solar export credit. CenterPoint runs a smaller residential Solar PV rebate ($135/kW DC, capped at 15 kW = up to ~$3,000 per project; SOLAR-ONLY, no battery adder) on a $1.5M annual budget. REP-dependent NEM: Tesla Electric (Fixed plan, Powerwall) and Octopus's Intelligent Octopus for Home are the representative solar-friendly plans we model today. Hurricane Beryl (Jul 2024) — 2.26M customer outages at peak, full restoration July 19 (Day 11), worst-hit pockets up to 2 weeks — anchors the resilience pitch.

Austin Energy — City of Austin + parts of Travis and Williamson counties · ~553K residential customers · municipal utility (city-owned, owns wires + supplies electricity)
Single-layer muni — Austin Energy owns wires and supplies electricity; no REP layer. Runs a Value of Solar Tariff (VoS) instead of 1:1 net metering: every kWh of solar produced is credited at the 2026 VoS rate of 9.91¢/kWh, separate from the 4-tier inclining-block retail rate the customer pays for grid imports. Battery does not increase VoS revenue (VoS is paid on production, not export) — value is consumption avoidance against the inclining-block rate, resilience for Uri-class events, and 10-year workmanship coverage. Austin Energy's $4,000 Residential Solar PV Rebate (raised from $2,500; current guidelines effective 7/1/2026) is a SOLAR-INSTALL rebate (minimum 3 kW-dc system, one per address since May 2018) — it does NOT apply to a battery-only retrofit (the default modeled customer); the rep guide covers the solar+battery sale case where it applies.

CPS Energy — San Antonio + surrounding 7-county footprint (Bexar, Atascosa, Bandera, Comal, Guadalupe, Kendall, Medina) · ~907K electric customers · largest US combined gas+electric municipal utility (city-owned, owns wires + supplies electricity)
Single-layer muni — CPS Energy owns wires and supplies electricity; no REP layer. Runs NET BILLING on dual registers (CPS Energy Delivered [Register 9] and PV Surplus [Register 10]): in-month exports offset imports down to zero, then Net Excess Generation credits at the sub-retail rate ($0.0165/kWh Oct–May, $0.0202/kWh Jun–Sep) — NOT 1:1 retail net metering (the prior "1:1" label was imprecise; corrected July 2026 from CPS Solar Billing Facts + DG Manual). OWNER-ONLY: CPS requires the net-metering customer to OWN the DG system (DG Manual 9th Ed, May 2024, §1.2.1: "The customer must also be the DG System's owner") — third-party-owned lease/PPA systems FAIL interconnection, so only owned systems (cash or financed) qualify. Net-metered batteries at CPS may NOT export power to the grid — backup + self-consumption only (no battery grid-export or export arbitrage) per §1.2.1. The SmartSource residential Solar PV Rebate SUNSET December 16, 2022 — no residential capex rebate is available today; commercial / non-profit / school tiers remain active. CPS runs a Battery Storage demand-response program that pays a $10 bill credit per dispatch event (performance-based, not a rebate). Uri Feb 2021 securitization recovers via the Fuel Adjustment Factor ($0.00080/kWh as of March 2024); multi-year base-rate increases (2022 +3.85%, 2024 +4.25%) layer on top.

El Paso Electric — City of El Paso (all of El Paso County) + parts of Hudspeth and Culberson counties (Van Horn, Sierra Blanca) · ~310-320K TX residential customers · regulated IOU on the WECC grid (NOT ERCOT)
Regulated IOU — EPE owns wires AND supplies electricity; no REP layer. The structural outlier of the TX build: EPE is on the WECC grid, not ERCOT. Uri Feb 2021 was an ERCOT collapse — only ~3,000 EPE customers lost power for under 5 minutes (post-2011 winterization investment + the Montana Power Station). PUCT regulates the TX side (NMPRC the NM side); EPE files multi-year base-rate cases through PUCT. Residential NEM CHANGED July 1, 2025: pre-July-1-2025 systems grandfathered at 1:1 within month with surplus rolled forward; new systems are capped at 50 kW, export credit is at avoided-cost (~3-5¢/kWh) limited to 10% of past-year usage, $85 application fee, $30.25/mo minimum bill. EPE runs a Home Battery Incentive via a Base Power pilot: the first 500 installed homeowners receive up to $500 ($250 per battery per the pilot terms — the $500-vs-$250/battery reading is UNCONFIRMED; channel: EPE/Base Power pilot docket). Solar pairing NOT required (standalone BYO-battery backup on Base Power hardware). No broader residential PV rebate. PUCT Docket 57568 approved Feb 2026: $33M revenue increase, ROE 9.4%, average residential bill ~$98 → ~$111 (+$13/mo), effective May 2026.

AEP Texas — Coastal Texas (Corpus Christi, Brownsville, Rio Grande Valley) + West Texas (Abilene, San Angelo, Vernon) · ~820-850K residential meters (~1M total premises) · TDU only (wires and delivery; REP supplies electricity)
TDU only — AEP Texas owns the wires across two distinct territories (Coastal RGV + West Texas) and sets delivery charges; the customer's REP (Retail Electric Provider) sets the retail rate and the solar export credit. AEP Texas SMART Source is OPEN for Program Year 2026 (renamed from Solar PV — now covers distributed solar, energy storage, and EV charging), $4,250 residential cap: solar tiers $1,250-$2,750 + a $1,000 energy-storage adder + $500 EVSE. The storage adder is CONFIRMED SOLAR-GATED (verbatim: Energy Storage equipment is only eligible if installed with qualifying solar equipment) — a standalone battery retrofit does NOT qualify. Exact PY2026 application open date UNCONFIRMED (projects must complete by Nov 30, 2026). REP-dependent NEM: Tesla Electric (Fixed plan, Powerwall) and Octopus's Intelligent Octopus for Home are the representative solar-friendly plans we model today. Dual resilience profile: coastal hurricane exposure (Hurricane Hanna 2020 took out ~152K RGV customers; Beryl 2024 largely spared AEP TX) plus West Texas extreme heat.

TNMP (Texas-New Mexico Power) — scattered Texas service areas: Gulf Coast (Galveston Island, Texas City, La Marque, Dickinson, League City, Friendswood, Alvin, Angleton, Brazoria, West Columbia, Sweeny), North-Central Texas (Lewisville, Pilot Point, Princeton, Farmersville, Glen Rose, Hamilton, Gatesville, Clifton, Meridian, etc.), and West Texas (Kermit, Pecos, Fort Stockton, Sanderson) · ~220K residential customers (~260K total premises) · TDU only (wires and delivery; REP supplies electricity)
TDU only — TNMP owns the wires across a scattered Texas footprint and sets delivery charges; the customer's REP (Retail Electric Provider) sets the retail rate and the solar export credit. TNMP's residential Solar+ subprogram (within the Res/HTR Standard Offer Program) runs a $1,000 storage adder + $500 EVSE on top of solar tiers, $4,250/premise cap — CONFIRMED SOLAR-GATED (verbatim: Energy Storage Equipment is only eligible when installed with qualifying solar equipment); a standalone battery retrofit CANNOT qualify. NOTE: COMPASS is TNMP's COMMERCIAL energy-efficiency program — the residential storage adder lives in the Res SOP Solar+ subprogram, not COMPASS (corrected July 2026). Treated as not applicable to the battery-retrofit default modeled here; the projection does not credit it. VERIFY (LOW): 2026 vs 2025 Res SOP rate refresh via tnmp.com 2026 Res/HTR SOP manual. REP-dependent NEM: Tesla Electric (Fixed plan, Powerwall) and Octopus's Intelligent Octopus for Home are the representative solar-friendly plans we model today. Galveston Island exposure makes coastal hurricane the primary resilience driver for that part of the footprint (Hurricane Ike 2008: 113K customers — 100% of TNMP Gulf Coast service area — without power; ~$30-35M restoration cost). Pending PUC Docket 58964 (filed Nov 2025) requests $2.8B rate base, materially larger than the prior $835M.

Entergy Texas — southeast Texas from the Louisiana border westward (Beaumont, Port Arthur, Orange, Conroe, Huntsville, Lufkin, Nacogdoches, Bryan/College Station) · ~538K customers across 27-28 counties · regulated, vertically integrated IOU on the MISO South grid (NOT ERCOT)
Regulated, vertically integrated IOU — Entergy Texas owns the wires AND supplies electricity; NO REP shopping (the other non-ERCOT single-layer entry alongside EPE). Grid is MISO South, NOT ERCOT — Entergy TX joined MISO Dec 2013. Uri Feb 2021 reached Entergy TX as MISO-directed rolling outages, not the ERCOT-collapse multi-day blackout. Residential solar is Schedule SQF (Option 2C): exports credited at AVOIDED COST (~3.6-3.9¢/kWh — Summer $0.03866, Winter $0.035865), NOT retail net metering; credits roll monthly and a check is cut when the balance owed the customer exceeds $50; $12.35/mo SQF charge (systems ≤50 kW with a bidirectional meter exempt). Interconnection agreements on/after Nov 29, 2017 get Option 2C. NO state credit (no TX income tax); federal ITC expired 12/31/2025; NO Entergy TX solar-INSTALL rebate (the $9K TX rebate is Oncor's deregulated TDU program — does not apply). BATTERY PROGRAM (corrected July 2026): Entergy TX now runs the Battery Storage Solutions program — a bring-your-own-battery demand-response program paying up to $325/yr, enrolling 2026 via greatergrid.com; eligible hardware is FranklinWH + Tesla. This is the ONE Texas program that accepts FranklinWH (the ERCOT REP VPPs — Tesla/Octopus/Gexa/Reliant — do not). Structure only; never project income beyond the published $325/yr cap. Rate driver is the PUCT rate-case cycle + a ~$2.4B gas-generation build (~1.2 GW) + industrial/data-center load growth (+19.7% summer peak by 2028) + storm-recovery securitization — MISO capacity, NOT the PJM 833% pattern. TODO(entergy-tx-verify-rate): rate-case ask ~$111→~$137/1000kWh (~23%); PUCT-approved figure unconfirmed — rates illustrative, flagged.

Lubbock Power & Light (LP&L) — City of Lubbock · ~101,000 meters · municipally owned TDU (City of Lubbock) · deregulated since March 2024 · ERCOT (SPP→ERCOT migration completed Dec 2023)
TDU only — LP&L owns the wires and sets delivery charges; the customer's REP sets the retail rate and the solar export credit. LP&L is MUNICIPALLY OWNED (City of Lubbock) — the ONLY municipal TDU in our deregulated TX book. NO TDU rebate of any kind — the Oncor $9K does NOT apply here. Newest ERCOT market: retail choice live only since March 2024; many customers are still on randomly assigned default REPs and have never shopped. REP-dependent NEM: Octopus's Intelligent Octopus for Home (Enphase / SolarEdge) and Gexa Solar Buyback 12 are the representative solar-friendly plans confirmed in LP&L territory. Tesla Electric availability UNCONFIRMED.
