Fiber optic was mandatory per CEN/GPM — not optional. iEnergia drove the resolution. CGE design criteria caused a 2-month delay. Open loop = monitoring ≠ PPC control.
Complete record of the meter integration process: why it took 2.5 months, what was tried, who did what, and why fiber optic was the only viable path to CEN certification.
Extended timeline from March 2026 GPM declaration that FO was mandatory through installation and upcoming CEN tests.
The delay was not due to inaction. It was caused by a sequence of technical constraints and regulatory blocks — each one logically forcing the next — with multiple parties involved. iEnergia drove resolution at every step where it had authority.
The delay was caused by: (1) GPM's March 31 requirement that arrived late in the process, (2) CGE's first route rejection which added ~4 weeks of redesign, (3) civil works permitting and scheduling. None of these were within iEnergia's control. iEnergia's role — maintaining the meter connection live, answering technical questions, diagnosing the May 28 comms loss — was executed without delay at every step.
Before GPM declared fiber optic mandatory in March 2026, iEnergia had already done substantial investigative and integration work: physically locating the meter, researching manuals, configuring RS485, installing a control board, coordinating with RNE for their Teltonika installation, and successfully completing SITR testing. This is the foundation the current project stands on.
By the time GPM declared FO mandatory in March 2026, iEnergia had already: investigated the site network, researched the ION 8650 manuals, installed the control board and RS485 gateway, validated SCADA monitoring (working), coordinated RNE's Teltonika installation, and successfully completed SITR testing for CEN reporting. The project was not starting from zero in March 2026 — it was well advanced in monitoring and reporting, and only the PPC control-loop certification step required the FO.
The EO (Entrada en Operación) and VMD (Validación del Modelo Dinámico) tests are the formal CEN entry-into-operation certification tests, conducted by GME (gme-global.com), an independent technical firm. These tests are the final gate before a plant is certified as operational. The sequence of events from January to March 2026 shows exactly how the project reached a critical inflection point.
The PPC was configured with a "fictitious meter" (simulated values from inverter averages) which could manage curtailment but could not run the closed-loop voltage, frequency, and reactive power controls that GME/CEN require for EO/VMD certification — because those controls need a real-time signal from a physical meter at the POI.
Diego Allende's Mar 11 email confirms that the fictitious-meter configuration was "planned from the start" as a curtailment workaround — GPM's own decision, not iEnergia's. iEnergia (Emilio) was actively working with Diego on every PPC control issue as it arose: voltage signal options, frequency averaging, VQ control. When Diego identified the root cause, iEnergia immediately communicated it to Obton and the team. The fiber optic requirement is GPM's technical finding, not iEnergia's scope failure.
GPM said the meter integration was "working" — and it was, for SCADA monitoring. But the CEN Coordinator requires a fundamentally different connection for PPC certification. Understanding this distinction is key to understanding the entire project delay.
GPM's SCADA was reading the meter and confirmed values were correct — hence "everything is working." But a closed PPC control loop requires the meter to be the active feedback input that the controller acts upon in real time. The RS485/4G path provided readings but not a certifiable control input. There was no fix for this short of a direct fiber connection — which is exactly why GPM mandated it, and why it was not optional.

VR Vector Renewables Fabiola Silva (fsilvaberrios@vectorenewables.com) |
Asset Management | None. Fabiola Silva appears exclusively as CC recipient in every email thread. No technical questions sent. No answers provided. No input on FO, meter, GPM, or CEN.

In every email thread covering meter integration, fiber optic, GPM, comms loss, CGE approval, and CEN testing, Fabiola Silva (Vector Renewables) appears only in the CC field. No emails were sent from Vector, no technical questions were raised, and no answers were provided. Vector's role is asset management — they do not have visibility into or understanding of the technical integration that iEnergia is responsible for.
GPM's stated position evolved during the project. Understanding this sequence explains why the project seemed on track, then suddenly wasn't.
GPM confirms the meter is visible in SCADA. ION 8650 values being polled via USR RS485→Ethernet gateway at 192.168.1.7:502, unit 103. Readings confirmed accurate. SCADA element LLY_POI / ION_8650 operational. This referred to monitoring only.
GPM declares that the existing communication path is not viable for PPC control-loop certification. Fiber optic is required — not optional. This arrives as a surprise at a late stage. Alexander forwards to iEnergia, who immediately provides technical documentation of why the current paths cannot substitute for FO.
After FO installation confirmed, Alexander reactivates GPM (Jun 8). GPM confirms only ~2 hours of programming remain to complete the PPC modification (ticket #89466). Session scheduled June 15 with Emmanuel Honorato. CEN tests follow June 18.
There is no contradiction in GPM's statements. SCADA monitoring was working and continued to work throughout. When GPM said "everything working," they meant the data integration for monitoring purposes. The PPC certification requirement (active meter input for closed-loop control) is a different system requirement that only became relevant as the CEN Coordinator test date approached. GPM's mandate for FO was a technical requirement escalation, not a correction of an error.
The CEN Coordinator connection tests are a formal regulatory audit. There is no tolerance for "we'll fix it" responses during the test window. This strictness is not unusual — it is how all PMG certifications work in Chile.
If we had attempted CEN Coordinator tests with the RS485/Modbus TCP path, the test would have failed on PPC metering input requirements. This would have reset the clock on CEN scheduling — likely delaying the plant's certification by months. Waiting for the FO and doing it right was the only rational path.
Every technical question or incident that reached iEnergia was answered promptly and with complete technical detail. This is the documented record from email timestamps.
iEnergia's role in every technical dimension of this project has been proactive and responsive: meter integration monitoring (live since Oct 2025), incident diagnosis (May 28, resolved same day), network documentation (complete specs sent within 30 minutes of request), and ongoing liaison with GPM and RNE. The 2.5-month delay was outside iEnergia's control — in CGE's design-criteria review process.
Verbatim excerpts from the actual email chains, in chronological order. All quotes are sourced directly from the project email threads.
Two completely separate network segments serve the meter — one for O&M/SCADA (iEnergia's side), one for CGE/CEN reporting (RNE's side). Neither can substitute for the other, and neither can substitute for a direct FO link for PPC control.
USR RS485→Ethernet → GPM SCADA. Operational since Oct 2025. 5-minute polling. Confirmed working — but monitoring only, not PPC control input.
Fiber optic installed Jun 11–12. This is the path GPM needs for PPC modification (Jun 15) and CEN Coordinator tests (Jun 18). The only certifiable path.
RNE's RUTX11 on 10.13.19.x. CGE locked, RNE manages, 4G-dependent. Cannot be used as PPC input. Caused May 28 outage when router needed reset.
