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.
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.
The combined electricity-and-gas regulator. Issues the Resoluciones CREG that compose the grid code framework and the wholesale market rules.
The system operator, ASIC and LAC. Receives technical filings, operates the SIN, settles the wholesale market.
The Colombian interconnected system. ~20 GW installed; hydro-dominant with rapidly growing wind (La Guajira), solar and BESS.
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.
The connection application dossier filed under Resolución CREG 075/2021 framework. Includes technical scope, equipment data, dynamic models and system-impact studies.
Power flow, short circuit, stability and protection coordination studies. Filed under CREG 030/2018 and related resolutions for autogeneración, cogeneración and wholesale-market generation.
Periodic and event-driven technical compliance reports filed with XM. Cover AGC participation, AVR/governor performance, ride-through events, and ancillary services delivery.
Operational procedure conformance — telemetry, AGC integration, real-time data exchange with XM. Testing coordination only; equipment install and comms stay with the integrator.
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.
Which CREG resolutions apply. XM technical contact. Cross-reference matrix with the applicable connection process amendments.
Field test data, dynamic models, connection-study results consolidated. Cross-checked against the CREG framework and XM submission conventions.
Solicitud de Conexión + supporting exhibits drafted in Colombian Spanish at source. XM format conventions and CREG citations aligned.
Lodging with XM technical review. Query response within review windows. Defense through approval and continuing-compliance reporting setup.
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.
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.
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.
Issued by CREG under the Ley 143/1994 statutory framework. The resolutions below are the most active for generation compliance work as of 2026; XM operational procedures provide the dispatch and settlement overlay.
