A “Smart Port”: Power System First, Logistics System Second

Puerto de Chancay is often described as a next-generation “smart port,” but the engineering reality is straightforward: it is a large, electrified industrial system where production capacity is directly bounded by power availability and power quality. Electrified quay cranes, yard cranes, electric tractors, automation platforms, security scanning, cold-chain warehousing, and a centralized control center all shift the port’s core productivity onto the electrical backbone.

That is why the Chancay load profile resembles heavy industry more than conventional commercial facilities: continuous demand, large step changes, and a high density of power electronics. For ODES, this is exactly the boundary where secondary systems—protection, control, auxiliaries, and maintainability—decide whether the site is stable and operable over the long term.

1) Why Chancay Becomes a Power-Intensive Industrial Load

Electrification + automation creates continuous, high-consequence demand

A smart port replaces diesel mechanical work with electrical work. The primary loads are:

Electrified lifting systems (quay and yard cranes)
Electrified vehicles (tractors, transfer vehicles, remote-operated fleets)
VFD-driven auxiliaries (pumps, fans, HVAC, material handling)
IT/OT systems (control center, communications, security, scanning)
Cold-chain and warehousing electromechanical systems

This combination creates a load that is both large and operationally sensitive: brief voltage dips, poor power quality, or loss of station service power can trigger nuisance trips, controller resets, and disrupted workflows.

Demand magnitude and market participation implications

Project analyses indicate Chancay demand on the order of 28.82 MW, large enough to be treated as a major customer category and to justify structured procurement strategies such as long-term PPAs and market participation mechanisms. For planners, that demand level also means the grid interface must be engineered with a clear reliability and availability objective, not just a “connection approval.”

2) Why the Grid Interface Goes Straight to 220 kV—and Why That Matters

The connection architecture described for Chancay is a 220 kV supply with a 220/22.9 kV substation, using 220 kV GIS and double-busbar arrangements, plus 22.9 kV switchgear (multi-feeder distribution) and reactive compensation planned at two × 4.5 Mvar.

This is an important signal: the project is not treating the port as a simple feeder load. It is treating it as a system node whose performance depends on:

Switching reliability and maintainability (GIS/busbar arrangements)
Reactive power compensation and voltage control (VFD-dense load behavior)
Protection selectivity and event localization
Station service power robustness for the entire secondary layer

Reactive compensation is not cosmetic here. A port with heavy VFD density can exhibit significant reactive power demand and voltage fluctuation. If compensation, voltage control, and protection coordination are not engineered together, the plant may remain connected but operate with chronic voltage excursions and repeated nuisance operation at the MV level.

3) ISA CTM’s Delivery Risk Is Not Just “Build the Line”

Consorcio Transmantaro (ISA CTM) is positioned as a key delivery party in bringing power to the port—covering engineering, financing, permitting, construction, and long-term operation. In a 220 kV / GIS-based connection, “delivery success” has two hard requirements:

Energize and synchronize safely, first time
Maintain availability and restore quickly over decades

In practice, these outcomes are heavily influenced by the secondary system:

Control circuit resilience (trip/close reliability, correct interlocks)
Auxiliary power continuity (AC/DC supplies, redundancy, transfer behavior)
Event visibility (alarm architecture, SOE consistency)
EMC robustness (VFD environment + long control wiring + frequent switching)
Maintainability (module standardization, predictable spares, clear diagnostics)

If these are weak, the project pays twice: first during commissioning (“why does it behave differently on site?”), then during operation (“why is fault localization taking so long?”).

4) What “Secondary-System Readiness” Looks Like for a Smart Port Substation

A 220/22.9 kV substation feeding an electrified port is defined by frequent operational switching, dense MV feeders, and high consequence of downtime. The secondary system should therefore be designed around four engineering outcomes:

A. Deterministic breaker control circuits

For HV/MV switchgear, breaker control circuits must be consistent, verifiable, and immune to induced transients:

Anti-pumping (anti-repeat close) logic implemented as a defined function block
Trip circuit supervision to detect open circuits, supply loss, or abnormal coil paths before they become failed operations
Operating relays sized and specified for the actual control circuit duty
Coil pickup/reset thresholds and dropout delays defined to minimize nuisance operation

B. EMC robustness as a design input

Ports are VFD-dense. That means high EFT/burst stress, surge exposure, and common-mode disturbances on control wiring. The secondary design should use:

EMC-appropriate interposing relay architectures (EMC-enhanced auxiliary relay where needed)
Clear segregation and bonding/shield termination practices
Control power supplies with defined immunity and transient ride-through behavior

C. Station service power continuity and visibility

A substation can remain energized while the secondary layer collapses if control power is weak. The key requirement is not only “dual supply exists,” but that transfer behavior is engineered:

Defined automatic transfer logic (AC and/or DC as required)
Alarm contacts for source loss, output loss, and transfer events
Avoidance of oscillatory transfers via proper thresholds and dropout delay strategy

D. Operational alarms that reduce time-to-repair

A smart port does not tolerate long fault localization cycles. Alarm architecture should be structured:

Fault annunciation for critical DC/AC auxiliary power states
Clear separation between “source abnormal” and “load abnormal” events
Wiring and point lists that allow operators to correlate switching events, alarms, and restoration actions quickly

5) Where ODES Fits in an ISA CTM Delivery + O&M Collaboration

ODES is not positioned as “a component supplier,” but as a provider of standardized, panel-level modules that reduce wiring ambiguity and improve reliability and maintainability in control circuits. For an ISA CTM delivery and O&M perspective, there are four practical cooperation paths:

1) Project supply of secondary function modules

For breaker control circuits and station service systems:

Anti-pumping relay modules
Trip circuit supervision relays
EMC-enhanced auxiliary relays for long-cable / high-interference circuits
Fault annunciators (centralized alarm and event visibility)
Control power supplies and DC supervision relays
AC/DC dual-supply transfer modules where required

2) “Modular packaged” secondary subsystems

Deliver standardized “control / alarm / redundancy” subassemblies with locked interfaces and wiring logic at the drawing stage—reducing site rework and uncontrolled wiring variation.

3) O&M reliability co-development

Create a practical O&M toolkit around the delivered secondary modules:

Spare parts list and replacement strategy
Fast fault localization guides aligned to actual alarm structure
Periodic health checks for control power and key breaker circuits
Feedback loop to improve disturbance immunity and service life design

4) Local delivery and service coordination

For long project cycles and tight commissioning windows, a local support plan (inventory, training, application notes, and commissioning support) directly improves energization confidence and restoration performance.

Conclusion

Chancay is not “just a port connection.” It is a 220 kV-class industrial power node with high electrification density and high operational sensitivity. In that context, the decisive engineering layer is not only primary equipment selection, but secondary-system reliability: deterministic breaker control, robust auxiliary power, EMC resilience, and alarm visibility that reduces restoration time.

This is where ISA CTM’s delivery and long-term availability objectives intersect directly with ODES’s strengths: standardized, engineering-grade modules for protection and control circuits—built to make complex sites more stable, more maintainable, and more verifiable.

If you are evaluating secondary-system delivery risk for 220/22.9 kV substations feeding electrified ports—breaker control circuits, auxiliary power continuity, EMC robustness, and alarm architecture—ODES can support a practical design review and provide standardized module libraries for consistent implementation.
