CFE interconnection turns your solar installation into a system that actually reduces — and potentially eliminates — your electricity bill. The process is technical but predictable: CFE has defined timelines and a specific document list. Most delays are not bureaucratic failures; they are incomplete packets.
Quick view
Complete guide to CFE's Distributed Generation process in Los Cabos: required documents, 13 and 18 business-day timelines, rejection causes, and a pre-filing checklist.
Net metering: generation and consumption are netted under the same supply contract. Net billing: consumption and energy sold to CFE are billed separately. Total sale: the generator sells all output with no self-consumption contract. For DAC households in the Corridor, net metering almost always produces higher savings.
Residential properties in Los Cabos are on low-voltage supply. Confirm this on your current bill — the application form and requirements differ between voltage levels.
Some installers still quote 0.5 MW because that is what older CFE materials show. The current legal framework sets the cap at 0.7 MW. A competent installer knows the difference.
1) Completed interconnection application. 2) Site-location sketch. 3) Current paid CFE bill for the linked service account. The account holder must be the one who signs the application.
Quick read
Verify on your CFE bill that you are on the DAC tariff, that the account holder can sign the application, and that your supply is low voltage.
Decide between net metering, net billing, or total sale. For most DAC households in Cabo, net metering maximizes savings.
The installer must prepare the diagram with the exact module and inverter models that will be installed. Data sheets and compliance certificates are part of the filing packet.
Deliver completed application, site sketch, single-line diagram, equipment data sheets, and current CFE bill. Request written confirmation that the packet was accepted — that is when the official clock starts.
CFE schedules an on-site inspection to verify the installation matches the documents and that disconnect devices and SPDs are correctly installed. The installer must be present.
After a successful inspection, CFE issues the interconnection contract. Sign it, keep a copy. Your next CFE bill should reflect the generation compensation.
Legal framework
Distributed Generation is defined in Mexico as systems below 0.7 MW connected to low or medium-voltage distribution networks. Some older CFE materials still cite the previous 0.5 MW threshold — that figure is outdated. A competent installer knows both.

The document packet
CFE does not start the official response clock until it receives and accepts a complete filing. A single missing or incorrect document restarts the process.
1) Completed interconnection application. 2) Site-location sketch. 3) Current paid CFE bill for the linked service account. The account holder must be the one who signs the application.
4) Single-line diagram. 5) PV module data sheet. 6) Inverter data sheet with compliance certificate. These three documents must match exactly what gets installed.
The installer files the packet with 'typical' equipment models and installs whatever is in the warehouse. CFE verifies on site. Any discrepancy triggers rejection. Require the packet to be prepared with exact model numbers before the installation date.
Official timelines
CFE has legally defined deadlines. The clock starts when CFE confirms in writing that the packet is complete — not when you submit it.
For most residential low-voltage systems that do not require a network technical study.
When the installed capacity could affect the circuit's maximum load. Less common in Corridor residential zones.
Packet rejected for incompleteness (clock restarts), installed capacity not lower than expected circuit load, or post-installation capacity increases requiring re-study.
Rejection causes
CFE's four main rejection grounds are all avoidable with proper packet preparation.
1) Incomplete packet (most common). 2) Installed capacity not lower than expected circuit load. 3) Technical non-compliance (NOM-001-SEDE, disconnect devices, SPDs). 4) Post-approval capacity increases without a new application.
The service number on the CFE bill must match exactly the address and account holder of the system. A data error invalidates the application.
CFE assesses whether your system's injection could raise circuit voltage beyond regulatory limits. Rare in the residential Corridor but relevant for large properties with high base demand.
FAQ
The legal framework sets 13 business days for systems without a technical opinion, or 18 when one is needed. In practice, total time from installation to approval is typically 3 to 6 weeks, depending on how quickly a complete packet is accepted.
For most DAC households in the Tourist Corridor, net metering produces the highest savings. Every kWh you produce directly reduces what you pay at the DAC rate (7.249 MXN/kWh). Under total sale, CFE pays you a purchase rate that is typically lower than the DAC rate you are avoiding.
The packet becomes inconsistent with the actual installation. CFE verifies on-site during inspection. Model number mismatches trigger rejection and a full re-filing. Require any equipment change to be reflected in the documents before submission.
You can as the property owner, but it requires preparing the single-line diagram, obtaining data sheets with compliance certificates, and completing the technical application. In practice, the installer almost always manages it. Make sure the interconnection filing is explicitly included in what you are paying for.
The 0.5 MW cap was the previous limit for Distributed Generation. The current law updates it to 0.7 MW. For residential installations in Los Cabos this rarely matters in practice — domestic systems are 5–20 kWp — but an installer quoting 0.5 MW is working from outdated materials.
