Colombia · XM & CREG.

A grid code framework built on Resoluciones CREG, operated by XM (subsidiary of ISA), serving the SIN. Strong hydro base with accelerating wind, solar and BESS — the La Guajira and Caribbean offshore wind buildouts moving the IBR share rapidly.

Resoluciones CREG. Who runs it.

Colombia's grid code is structured as a series of Resoluciones CREG — regulatory resolutions issued by the energy and gas regulator that together define the technical rules of the Mercado de Energía Mayorista (MEM). The framework is administered through XM S.A. E.S.P. — a subsidiary of ISA (Interconexión Eléctrica S.A.) — which operates the Sistema Interconectado Nacional (SIN) and runs the wholesale market.

XM also acts as the ASIC (Administrador del Sistema de Intercambios Comerciales) and the LAC (Liquidador y Administrador de Cuentas) — a single integrated technical-and-commercial operator.

/ 02 · Document types we file

CREG filings.

Colombian filings combine connection-application dossiers (under CREG 075/2021 and successors) with the supporting connection studies, continuing-compliance reports, and operational-procedure conformance. The integrated XM / ASIC / LAC model means commercial and technical filings frequently cross-reference.

Spanish authorship is at source, in Colombian technical Spanish, aligned to the SIN's terminology and CREG resolution conventions.

Solicitud de Conexión

Connection request

Solicitud de Conexión al SIN

The connection application dossier filed under Resolución CREG 075/2021 framework. Includes technical scope, equipment data, dynamic models and system-impact studies.

Estudios de Conexión

Connection studies

Estudios de Conexión al SIN

Power flow, short circuit, stability and protection coordination studies. Filed under CREG 030/2018 and related resolutions for autogeneración, cogeneración and wholesale-market generation.

Reportes de Cumplimiento

Compliance reports

Reportes de Cumplimiento Técnico

Periodic and event-driven technical compliance reports filed with XM. Cover AGC participation, AVR/governor performance, ride-through events, and ancillary services delivery.

Procedimientos MEM

MEM procedures

Procedimientos de Operación XM

Operational procedure conformance — telemetry, AGC integration, real-time data exchange with XM. Testing coordination only; equipment install and comms stay with the integrator.

/ 03 · Submission process

Four phases. XM-aligned.

Colombian filings flow through XM's technical review process, with CREG resolution-compliance cross-references woven through every dossier. The integrated commercial-and-technical operator means filing language has to read fluently across both sides — connection studies and ASIC/LAC reporting share vocabulary and exhibits.

Native Colombian Spanish drafting is non-negotiable for first-review approval. The methodology travels from our Mexican practice; the local layer — XM's format expectations and Resolución CREG citation conventions — is what we tune per market.

/ 04 · Methodology ready

Engagement-ready. Renewable buildout aligned.

Colombia's renewable buildout — particularly the La Guajira wind cluster and the new BESS interconnections — is moving the SIN's dynamics fast. The compliance demand is on IBR ride-through, dynamic modeling accuracy and ancillary-service capability — all areas where our methodology is built for the modern grid, not the old one.

We have not yet filed a Solicitud de Conexión through XM on behalf of a Colombian client. What we have is the methodology, the language and the framework knowledge, ready to mobilize on confirmed scope.

What's in place today

Colombia: methodology, language, IBR fluency — all ready to mobilize.

Working inventory of what's prepared and ready for a Colombian engagement. The track record is yet to be built in-market; the practice that builds it is already operational.

Native Colombian Spanish authorship — local technical terminology
Resolución CREG cross-reference matrix maintained
Cross-platform simulator fluency (PSS®E, DIgSILENT, EMTP, ETAP)
IBR / BESS capability — relevant for La Guajira wind and solar buildouts
Engineering standards overlay (IEEE 421.5, IEEE 2800, IEC 61400-27)
Familiarity with the integrated XM / ASIC / LAC operating model
/ 05 · Standards & references

CREG & XM references.

The Colombian regulatory framework is a stack of CREG resolutions on top of the foundational Ley 143/1994. The Código de Operación (Res CREG 025/1995) and the connection-process resolutions (CREG 060/2019, CREG 075/2021, CREG 030/2018) are the most active for current compliance work. XM publishes operational procedures that overlay the regulatory framework.

International engineering standards (IEEE, IEC, ANSI) provide the test methodology and equipment-model overlays the Colombian framework references.
