RETIE
Also known as: Technical Regulation for Electrical Installations.
Definition
RETIE is Colombia's Technical Regulation for Electrical Installations. It sets the safety requirements electrical installations must meet, solar ones included, to protect people and property.
Sources: RETIE — Technical Regulation for Electrical Installations (opens in a new tab)
Its purpose is safety: adequate protections, earthing, labelling, clearances, material quality and the competence of whoever carries out the work. A solar installation is no exception; on the contrary, it brings direct current onto the roof, elevated voltages and a connection point with the grid, all of which make compliance especially relevant.
On a grid-connected project, RETIE compliance is not a decorative formality: the grid operator verifies it within the connection process, and failing it blocks approval. That is, in practice, one of the most frequent causes of delay in legalizing badly executed systems.
It also has consequences outside the process. An installation that does not comply with the regulation can affect the property insurance cover in the event of an electrical incident and complicates any warranty claim. So it is worth insisting in writing that the proposal covers RETIE compliance and the corresponding documentation.
The essentials of RETIE
- A mandatory technical regulation for electrical safety in Colombia.
- It applies to photovoltaic installations too.
- The grid operator verifies compliance during the connection process.
- Non-compliance can affect the property's insurance and warranties.

Frequently asked questions about RETIE
Does my solar installation need RETIE certification?
Every electrical installation in Colombia has to comply with the regulation, and during a solar system's connection process the grid operator requires the documentation evidencing it. The specific scope depends on the type of project; the installer should state what applies to yours and who handles it.
What happens if my installation does not comply with RETIE?
The grid operator can refuse the connection, leaving the system unlegalized and with no access to net metering. Beyond that, a non-compliant installation is a real safety risk and can complicate the property insurance cover in the event of an electrical incident.
