CFE bidirectional meter
We manage the interconnection contract and the meter change, so your surplus energy is credited on your CFE bill under net metering.
CFE interconnection
CFE interconnection for your solar system, without rework
We run the full filing with CFE, Mexico's state-owned electric utility: engineering, application package, contract and bidirectional meter. An independent accredited unit does the verification.
What is included
Everything CFE requires, handled by us
Complete technical package
Diagrams, calculation report and documentation that conform to NOM-001-SEDE-2012, Mexico's electrical installation standard, so CFE does not reject your application.
Verification on track
CFE requires a verification report from an accredited, independent verification unit. We get your installation ready to pass the first time and coordinate the process.
The CFE filing, start to finish
You don't stand in line at CFE offices or chase case numbers. We run the application, the follow-up and the signing of the interconnection contract.
Three paths
PSE handles CFE interconnection three ways
Distributed generation is the CRE (Mexico's energy regulator) framework for systems up to 0.5 MW. Each case has its own voltage level, its own application package and its own verification report. We take you down the right path for your system.
Low-voltage interconnection
Interconnection application under distributed generation at low voltage: contract, bidirectional meter and net metering, so your solar surplus is credited month by month on the CFE bill.
Medium-voltage interconnection
Filing for systems up to 0.5 MW under distributed generation: technical package, interconnection study and contract signing with CFE. We file under current regulations and keep the process moving.
Filing for systems already installed
Already have the panels but no interconnection? We check that the installation meets NOM-001-SEDE-2012, assemble the application package, coordinate verification with an independent accredited unit, and manage the contract and the meter with CFE.
How your system works
From sunlight to a lower CFE bill
Every kWh you generate is a kWh you no longer buy from CFE. The surplus is fed into the grid and credited to you through the bidirectional meter.

Your bill
A recurring expense becomes an asset on your books, with a clear return on investment.
The PSE method
Done right the first time
We control the two pieces that depend on execution: the engineering of the application package and the electrical work (through IED, our sister company). We assemble a package that conforms to the current NOM-001-SEDE-2012 and file under the CRE's distributed generation rules (up to 0.5 MW).
Verification is carried out by an accredited unit that is independent of the installer, which is what makes the report valid. We prepare your installation to comply and coordinate the process, so you do not have to chase it.
- Engineering and technical package for CFE
- Interconnection application and follow-up
- Coordination of the independent verification
- Balance-of-plant electrical work through IED
- Compliance with NOM-001-SEDE-2012 and CRE rules
- Interconnection contract and bidirectional meter

Why PSE
Fewer rejections, fewer resubmittals
Engineering and paperwork with no rework
The number one reason for rejection is a poorly assembled application package. We deliver diagrams, calculation report and documentation that conform to the standard from the start, built to pass the first time.
Electrical work with IED, our sister company
If the installation needs adjustments to meet the standard, the balance-of-plant electrical work (service entrances, switchboards, conduit runs) is carried out by IED, part of Grupo Empresarial CIAE. Critical work is not handed to outside contractors.
Independent verification, as it should be
The verification report is issued by an accredited unit that is independent of the installer, which is what makes it valid. We prepare the installation to comply and coordinate the process, so you do not have to chase it.
Full compliance with CRE and NOM rules
We file under the CRE's distributed generation rules (up to 0.5 MW) and design to the current NOM-001-SEDE-2012. Done right the first time, to avoid rejections and rework.
Frequently asked questions: CFE interconnection
How long does CFE interconnection take?
For low-voltage residential and commercial systems, the interconnection contract and the meter change usually take a few weeks once the application package is correct and the verification report has been issued. At medium voltage (up to 0.5 MW) it takes longer, because CFE runs an interconnection study. The biggest cause of delay is a poorly assembled application package. We deliver it complete from the start, so you avoid resubmittals.
What is the verification report, and why does CFE require it?
It is a report certifying that your electrical installation meets NOM-001-SEDE-2012. An accredited verification unit that is independent of the installer issues it, and CFE requires it before signing the interconnection contract: without it, the bidirectional meter is not installed. The independence from whoever did the installation is exactly what makes it valid. PSE prepares your installation to comply and coordinates the process with the verification unit.
I already have an installer. Do I still need the verification?
Yes. Verification is a CFE requirement regardless of who did the installation: it is a regulatory compliance report needed to interconnect. We can assemble the application package, coordinate verification with an independent accredited unit and manage the contract, even if another installer did the work. What we check is that the installation meets NOM-001-SEDE-2012 before it is submitted.
What happens if CFE rejects the application?
A rejection almost always comes from an incomplete application package, a faulty diagram or an installation that does not meet the standard. Because we control the engineering of the package and the electrical work (through IED, our sister company), we correct at the source whatever CFE flags and resubmit, without leaving you caught between suppliers who blame each other. Having the execution under one group reduces the risk of rejection at its root.
How much does CFE interconnection cost?
Interconnection under distributed generation carries no connection fee as such for low-voltage systems. What gets quoted is the engineering of the application package, the fee of the independent accredited unit that issues the verification report and, where it applies, balance-of-plant electrical work. At medium voltage, there may be costs tied to CFE's interconnection study, depending on the case. We give you the breakdown before we start, so you know exactly what you pay and why.
Can you handle only the interconnection if I already have the panels?
Yes. We can take a system that is already installed, check that it meets NOM-001-SEDE-2012, assemble the technical package, coordinate the verification report with an independent accredited unit, and manage the interconnection contract and the bidirectional meter with CFE. If the existing installation needs adjustments to meet the standard, IED, our sister company, carries out the electrical work before we submit.

The filing goes smoothest when the application package is built alongside the system design. These are the lines where we build it in from the start.
Commercial solar
For businesses on CFE's low-voltage PDBT rate or its medium-voltage GDMTO or GDMTH rates, the interconnection package is prepared along with the system design, so it does not hold up commissioning.
