Which utility serves this customer?
Each Texas utility has different net metering rules, rebate programs, and pitch angles. Selecting here loads the right calculator math and proposal template.
Oncor
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.
Lead with: REP buyback economics + ERCOT resilience (battery-retrofit default)
CenterPoint Energy
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.
Lead with: Hurricane Beryl resilience + REP buyback economics + ERCOT structural hedge
Austin Energy
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.
Lead with: Consumption avoidance + Uri-class resilience (battery-retrofit default)
CPS Energy
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.
Lead with: Net-billing self-consumption + post-Uri rate-case hedge + battery DR enrollment
El Paso Electric
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.
Lead with: Post-July-2025 NEM cohort + Not-on-ERCOT resilience + Sun Belt heat hedge
AEP Texas
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.
Lead with: RGV hurricane + West Texas heat resilience + REP buyback + ERCOT hedge
TNMP
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.
Lead with: Galveston hurricane resilience + REP buyback + ERCOT hedge (battery-retrofit default)
Entergy Texas
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.
Lead with: Gulf-Coast hurricane resilience + regulated single-provider rate protection (MISO, not ERCOT)
Lubbock Power & Light
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.
Lead with: Newest ERCOT market + REP buyback economics + ERCOT resilience (no TDU rebate)
