Deep dive

TRACE Telecom deep dive

A single Telecom Energy Efficiency Portfolio (TEEP) covering macro-towers, access, and supporting assets.

Network-wide MRV layer for telecom

TRACE Carbon Systems is designed as the MRV engine for a single Telecom Energy Efficiency Portfolio (TEEP) that spans the full energy stack: macro-towers, MSAG and access cabinets, key aggregation sites, and fuel anchors. The goal is to create one verified view of power flows, fuel usage, and reductions instead of scattered spreadsheets and partial meters.

  • Macro-towers and hybrid power sites (diesel, solar, battery, grid).
  • MSAG and access cabinets in the fixed network, including small street cabinets.
  • Aggregation rooms and small network sites where energy use is material.
  • Biodiesel supply points and exhaust checks as optional modules in later phases.

The same cryptographic MRV engine is applied across all layers, so a tower and an MSAG cabinet produce comparable, verifiable records that can be rolled up into one TEEP dataset.

Four-layer telecom MRV architecture

This layered approach is designed so that telecom operators, lenders, and verifiers can see not only the headline numbers, but also the integrity conditions behind each record.

L1 · Hardware keys and signing

Every 15 minute window of kWh by source, site ID, and flags is hashed and signed on device using a secure element. Public keys are anchored in a registry so records can be verified independently.

L2 · Clean signals and checks

Separate diesel, solar, battery, and grid signals are checked for basic consistency and energy balance. Suspicious intervals are flagged rather than hidden.

L3 · Time and place integrity

GPS time, RTC, and geofencing are used to detect time drift and device movement outside allowed perimeters, with flags attached to affected windows.

L4 · Conservative carbon math

Emissions and reductions are calculated using conservative factors and explicit uncertainty ranges, and the system fails closed when data quality is not sufficient for a given interval.

Proof-of-concept path for towers and access

Initial deployments focus on a small number of hybrid towers and, optionally, MSAG or access cabinets, to prove the MRV pattern in a low-risk way before scaling.

  • Representative set of hybrid towers across different grid conditions.
  • Optional fixed network pilot in one metro area using the same device profile.
  • Signed 15 minute windows with kWh by source and metadata for each site.
  • Continuous series of records over 60 to 90 days to test uptime and completeness.

Standards and finance integration

Telecom operators are under pressure to move from narrative commitments to verifiable evidence. TRACE Telecom is built so the same dataset can feed reporting and finance use cases with minimal rework.

  • Data model aligned with IFRS S1 and S2, ISO 14064-1, and telecom energy disclosures.
  • Conservative treatment of baselines and uncertainty to avoid over-claiming reductions.
  • API integration with international energy optimizers so realized savings can be proved, not just modeled.
  • Portfolio view that can back a single TEEP for green loans or sustainability-linked instruments.

The POC is framed as a stepping stone toward a larger portfolio, not a one-off pilot.

Deep dive

TRACE Ports deep dive

A Ports Energy and Emissions Portfolio built from shore power, reefers, cranes, and gensets.

Port-wide MRV for critical assets

TRACE Ports is designed as a light-touch MRV layer on top of existing meters and feeders. It concentrates on the assets where energy, emissions, and finance relevance are highest, and turns their energy flows into signed, asset-level records.

  • Shore power lines and reefer feeders at selected berths.
  • Large electric feeders serving cranes, warehouses, and terminal buildings.
  • Port-owned diesel generators supplying parts of the terminal.
  • Phase 2 expansion to fuel depots, yard equipment, and scrubber checks as needed.

All assets feed into a single Ports Energy and Emissions Portfolio, so terminal operators and port authorities can see where electrification is displacing diesel and auxiliary engine use.

Four-layer MRV engine for ports

The focus at the edge is precise kWh and integrity flags. Emissions and portfolio math are handled in the backend so factors can be updated without changing hardware.

L1 · Hardware keys and signing

Each Port Edge device signs a 15 minute JSON record that includes asset ID, window start and end, kWh by source, and validation flags.

L2 · Clean signals and checks

Meter readings are checked for negative kWh, impossible jumps, and missing samples. Intervals with issues are flagged for later treatment.

L3 · Time integrity and location

GPS time and RTC holdover provide accurate UTC timestamps and confirm devices remain inside the configured port perimeter.

L4 · Conservative emissions logic

kWh is converted to tCO2 using local grid factors and diesel at 2.68 kg CO2 per liter, with uncertainty and completeness exported alongside central values.

Three-device ports POC

The initial ports proof of concept uses a narrow but representative configuration to show that the MRV engine works in a real terminal environment.

  • Device 1 on a shore power or reefer feeder (grid only).
  • Device 2 on a port diesel generator (diesel only).
  • Device 3 on a large electric feeder such as a crane or warehouse (grid only).
  • Same firmware image across devices, with configuration set per asset.

Link to reporting, shipping, and finance frameworks

Ports are under pressure from corporate climate reporting, shipping programs, and access to green finance. TRACE Ports is structured so one dataset can support all three.

  • Asset-level kWh and tCO2 that roll into IFRS S1/S2 and ISO 14064-based inventories.
  • Building blocks for future shore power and port electrification methodologies in shipping programs.
  • Data structures that can later link to AIS and terminal systems for vessel-level metrics.
  • Portfolio views that can support green loans or sustainability-linked instruments for terminals and port authorities.

The POC is framed as a base MRV stack that can be scaled out to more feeders, berths, and ports with minimal changes to the underlying device behavior.
