/ 01 · Who this is for

For the projects that have to survive review.

Compliance filings are the documents the regulator's planning and operations teams actually read — and the documents the lender's bankability assessment relies on. They are not paperwork. They are the artifact that converts months of testing and engineering into the approval that releases retention and closes interconnection.

Our clients fall into five archetypes. Each one needs the same thing in the end: a filing that gets approved on first review.

/ A

IPPs & Developers

New units approaching COD. Filings are the gate that releases the operator's interconnection acceptance and the lender's retention payment.

/ B

Utilities

Fleet retrofits, dispatch re-categorizations, and operator-mandated re-filing campaigns. Cross-jurisdictional reach matters as fleets span borders.

/ C

EPC Contractors

Handover gated on filing approval. Independent authorship preserves the EPC schedule and the owner's acceptance position simultaneously.

/ D

OEMs

Warranty triggers, dispatch categorization and post-retrofit re-filings. The regulator-facing document is often the trigger for commercial events.

/ E

Lenders & DFIs

Bankability hinges on regulator approval. Independent filing authorship underwrites the milestone that unlocks debt drawdowns and final commissioning.

One methodology · any framework

Authored in EN, ES, PT or AR — adapted to whichever regulator your project answers to. The practice is portable; the credential is the methodology, not the country.

Where the filing terminatesThe plant at full operation · The asset the regulator validates through the dossier
/ 02 · What we deliver

Six concrete deliverables. One approved file.

Every Compliance Filings engagement produces the same set of artifacts. You know exactly what arrives at the end of the campaign — and what the regulator, the lender and your EPC counterparty each receive.

Authorship is bilingual or trilingual at source — not translated post hoc. Reports are written in the regulator's language with the format conventions, citations and exhibit structure the regulator expects.

The asset behind every filingCombined cycle plant · The physical system the regulator approves through the dossier
/ 01

Compliance dossier

Master document aggregating test results, model packages, study reports and certificates into a single regulator-submission file. Built from the data; not bolted on.

/ 02

Format adaptation

Each regulator has its own dossier structure, exhibit numbering, signature block and submission portal. We deliver in the exact convention the regulator's review team expects.

/ 03

Multilingual authorship

Documents authored in English, Spanish or Portuguese — at source, not as translation. Technical accuracy preserved across languages, vocabulary aligned to each regulator's terminology.

/ 04

Portal submission

Upload to the regulator's submission system — SAPPSE (Mexico), ONS-Web (Brazil), the Coordinador portal (Chile), CAMMESA (Argentina), XM (Colombia), COES (Peru) — with full traceability.

/ 05

Query response

Regulator review teams ask questions. We answer them — technically, defensibly, in the language and timeframe the review window requires.

/ 06

Approval certificate

We stand behind the filing through final approval. The deliverable that closes the engagement is the regulator's approval certificate — not the submission receipt.

/ 03 · Inside the grid codes

How regulators differ. The methodology adapts.

Every grid code has its own document conventions, submission portals, test protocols and language quirks. Some require multiple report types per plant; some bundle everything into a single dossier; some demand local-language authorship while others accept English. The compliance filings methodology travels because it is built on fundamentals — testing rigor, multilingual authoring at source, regulator-portal fluency — not on country-specific habits.

The framework examples below give a sense of what we encounter in different jurisdictions. These are illustrative, not the limit of where we file — the methodology is region-agnostic. Engage with us about your specific framework, wherever it sits.

/ 04 · How we deliver it

Five phases. Auditable at every step.

Every Compliance Filings engagement follows the same disciplined methodology, scaled to the jurisdiction. Each phase produces specific artifacts that gate the next. The dossier that ships is traceable line-by-line back to the data and the engineering that produced it.

This is the methodology that survives regulator planning-team review on first read — which is the result every client actually wants.

/ 05 · Languages & capabilities

Native authorship. Portable methodology.

The depth of a filings practice lives in three things: language fluency, regulator-portal skill, and framework knowledge. We author at source in four native languages, operate directly in regulator submission portals wherever our clients file, and maintain working knowledge across the world's major grid code frameworks and engineering standards.

Where the engagement touches telemetry, AGC integration or SCADA signal lists, we coordinate and document the testing of those systems. The equipment install, commissioning and communication channels stay with the integrator and the operator.

Credentialed for regulator and lender review.

ISO/IEC 17020 accreditation as a Type A inspection body is in progress, expected to complete in 2026. The methodology and the regulator-relationship track record already meet the technical requirements — accreditation formalizes what is already in place.

The 50+ plants filed through SAPPSE form the deepest filings track record in the Mexican market available to an independent firm. Mexico anchors the practice; the other five jurisdictions are growing alongside regional client demand.

The Mexican filings practice.

Mexico is the deepest filings market GCE operates in — and the deepest filings practice an independent firm has built outside CENACE itself. Fifty-plus plants filed through SAPPSE under the Código de Red 2.0 three-stage process: pre-test documentation, field test campaign, commercial operation entry — all authored in Spanish at source.

The telemetry / ICT scope rule — where the engagement touches CENACE's ICT Requirements Manual (telemetry channels, RTU/UTR, SCADA signal lists, AGC integration, PMU and disturbance recorders), we coordinate and document the testing. The hardware install, the commissioning of the telemetry equipment, and the communication channels stay with the integrator and the operator. The same clean scope-line applies in Brazil, Chile and the other jurisdictions.

Services that feed the filing.

Compliance filings sit at the end of the engagement — they are where the work converts into approval. The data, reports and models that go inside the dossier come from the testing and studies practices upstream. Most clients buy the filing alongside the underlying work.
