Not ERCOT. EPE Western Grid.
Approval Before You Install.

El Paso solar permit drawings for City of El Paso and all El Paso County AHJs. El Paso Electric is NOT in ERCOT — no REP selection, net metering instead of buyback plans. EPE’s July 2025 rate case imposed a 10% export cap on new installations. And EPE requires written design approval before any installation begins. 297 sunny days. Free for first-time clients.

Two Things Most Installers Get Wrong in El Paso

No REP Selection. And EPE’s July 2025 Rate Case Changed Export Rules for New Installations.

Installers who work El Paso alongside ERCOT cities make two mistakes: they tell customers to pick a solar buyback REP (an ERCOT concept that doesn’t apply here), and they miss the July 2025 EPE rate case changes. El Paso Electric is a regulated IOU on the Western Interconnection — it handles generation, delivery, and interconnection as one entity. No REP. No ERCOT market. A completely different structure from Dallas, Houston, or Austin.

Pre-July 2025
EPE Net Metering — Prior to July 1, 2025 Rate Case
Standard monthly net metering — generation offset against consumption
No explicit export cap — size system to match or slightly exceed usage
Net excess credited at EPE Rate Schedule T-48
Systems before July 1, 2025 grandfathered on this plan
⚠️$30.25 minimum monthly bill regardless of solar production
Post-July 2025
EPE Net Metering — New Installations After July 1, 2025
⚠️Net metering only for systems under 50kW
⚠️Export cap: only 10% of prior year’s usage credited at net metering rates
⚠️Excess beyond 10% cap earns avoided cost — a few cents per kWh
⚠️$30.25 minimum monthly bill still applies
Right-sizing to consumption is now the critical design decision
⚠️ EPE requires written design approval before installation begins. Submit the plan set and interconnection application to EPE, receive email approval, then pull the city permit and install. Application fees: $85 for systems 1–100kW. Contractors who install before EPE approval risk building systems that fail interconnection — rework cost on installed equipment is significant.
Why El Paso Installers Outsource

Wrong Plan Set Format for EPE. Oversized Systems Past the 10% Cap. Installing Before Approval.

📋
ERCOT-Format Plan Sets Don’t Work for EPE Interconnection
EPE requires its own one-line format, site diagram, and generation disconnect documentation. Submitting an ERCOT-format plan set to EPE gets rejected — and since EPE recommends waiting for design approval before installation, a rejection delays the entire project. We build every El Paso plan set to EPE’s specific submission format.
📊
Oversizing Past the 10% Export Cap Hurts the Customer
Before July 2025, sizing at 100–120% of consumption was standard. Now, exports beyond 10% of prior year usage earn only avoided cost — a few cents per kWh. A system that pushes too much past the cap leaves the customer earning cents instead of full net metering credits. Right-sizing to consumption is the key deliverable for every new El Paso installation.
⏱️
Installing Before EPE Approval Is the Most Expensive El Paso Solar Mistake
EPE is clear: written email approval before panels go up. Contractors who build first risk systems that fail interconnection review. El Paso is not a self-certify-and-submit market. EPE reviews first. We flag this requirement in every El Paso deliverable and format plan sets for EPE submission alongside the city permit package.

El Paso Solar Market — 2026

Four Things That Define Solar in Sun City.

297 Days
Sunny Days Per Year — Best Solar Resource in Texas
El Paso averages ~297 sunny days per year with 5.5 to 6.0 peak sun hours daily — comparable to California’s Inland Empire. A system here produces 25–35% more electricity annually than the same system in Dallas or Houston. The irradiance makes El Paso one of the strongest solar ROI markets in the southern US.
10% Cap
Post-July 2025 Export Limit — Right-Sizing Is the Key Deliverable
New EPE installations after July 1, 2025 can export only 10% of prior year’s usage at net metering rates. Anything beyond earns avoided cost. Size the system to match consumption. Battery captures excess midday generation and dispatches it for evening use — keeping self-consumption high and exports low within the net metering threshold.
Western Grid
EPE Is on the Western Interconnection — A Simpler Solar Market Than ERCOT
El Paso Electric is a regulated IOU on the Western Interconnection — the same grid as California, Arizona, and New Mexico, completely separate from ERCOT. EPE handles generation, delivery, and solar interconnection as one entity. No retail competition, no REP selection, no market pricing volatility. EPE bills and credits solar under a single tariff — more predictable than ERCOT deregulation.
Fort Bliss
Largest US Army Installation — Government + Commercial Solar Market
Fort Bliss is one of the largest US Army installations in the country. The military presence drives government facility solar, EV fleet charging, and energy resilience projects. El Paso’s Borderplex economy — cross-border manufacturing, logistics, healthcare — creates a commercial solar market growing faster than residential in many zip codes.

FAQ

Questions El Paso Installers Ask Us

No. El Paso Electric (EPE) is a regulated investor-owned utility on the Western Interconnection — the same grid as California, Arizona, and New Mexico, completely separate from ERCOT. El Paso customers don’t choose a Retail Electric Provider. EPE handles generation, delivery, and solar interconnection as one entity. No REP selection step, no ERCOT pricing, no solar buyback plan comparison needed.
EPE’s July 2025 rate case changed net metering for new installations: (1) available only for systems under 50kW; (2) exports capped at 10% of prior year’s usage at net metering rates; (3) exports beyond that earn avoided cost — a few cents per kWh. Systems installed before July 1, 2025 are grandfathered. The $30.25 minimum monthly bill applies regardless of production.
Yes — EPE requires written design approval via email before installation begins. The workflow: submit plan set and interconnection application to EPE → receive email approval → pull city building permit → install. Application fee: $85 for systems 1–100kW, $230 for systems over 100kW.
Size to match consumption — don’t oversize. Exports beyond 10% of prior year usage earn only avoided cost. Battery is the right add-on: captures midday excess that would hit the export cap and dispatches it for evening use, maximizing EPE net metering value without oversizing the array.
El Paso uses NEC 2020 as the working electrical standard. NEC 2026 adoption had not been confirmed for El Paso as of July 2026.
Yes — Sunland Park, Las Cruces area, and New Mexico EPE addresses. NM follows New Mexico permitting with EPE’s NM interconnection process and NM Public Regulation Commission rules — different from the Texas side. We confirm state jurisdiction and AHJ per address.
Most El Paso residential plan sets ship in 24 to 48 hours. Battery same day. Commercial: 3 to 5 business days. Rush available.
