FORCE ESD at a 500 kW Port Office: A 24/7 Operations Case Study

Ports are among the few environments where electricity is consumed without pause. Cargo handling equipment, terminal lighting, security and monitoring systems, IT infrastructure, and HVAC all draw power in shifts that rotate through all twenty-four hours of the day. At a port office serving a busy terminal, the electrical load rarely falls to zero, so even small inefficiencies in power quality accumulate into significant costs over a year of continuous operation.

This case study examines a 500 kW FORCE ESD installation at a port office, one of the installation references documented by ENPOSS. It covers why port facilities are a strong fit for energy saving devices, how the no-circuit FORCE ESD is deployed, and what operators should measure to evaluate savings at their own site.

Why 24/7 Operations Are a Natural Fit for Energy Saving Devices

A port office is not a standard commercial building. The administrative floors may follow office hours, but the surrounding terminal runs around the clock. Refrigerated storage, quay cranes, gate systems, surveillance cameras, communication networks, and server rooms create a load profile with no true off-peak period. Every hour of electrical inefficiency is repeated roughly 8,760 times a year.

That continuous baseline changes the economics of energy saving. In an office building that runs twelve hours a day, a given inefficiency costs half of what the same inefficiency costs in a facility that never powers down. Continuous loads also mean that poor power quality, including reactive power, harmonic distortion, and voltage imbalance, never gets a rest period to dissipate. These effects generate excess heat in cables and distribution panels, accelerate wear on electrical equipment, and quietly inflate the kilowatt-hours billed at the meter each month.

The practical challenge for port operators is that traditional efficiency measures are difficult to apply. Replacing equipment or rewiring distribution systems in a facility that cannot halt operations is rarely viable. A solution that improves power quality without touching the existing circuit, installed at the main panel, addresses that constraint more directly. Installation still requires briefly lowering the main breaker, so a short outage window has to be planned with the facility.

The Installation: A 500 kW FORCE ESD Deployment

The installation covered in this case study involved a FORCE ESD matched to the port office's 500 kW electrical system. The FORCE product line spans capacities from small single-phase models up to 1,000 kW, so the device is matched to the facility's actual load rather than forcing the site to adapt to the equipment.

True to its no-circuit design, the FORCE ESD was connected to each phase of the RSTN on the secondary side of the main breaker by a qualified electrician. The device sits within one meter of the electrical panel, connects in parallel, and draws no current itself. No existing wiring is modified. Installation requires briefly lowering the main breaker, so the electrician and the facility should plan a short outage window.

How the FORCE ESD Works Around the Clock

The FORCE ESD is built around Tourmaline, a natural mineral that generates free electrons and improves current conductivity when exposed to electromagnetic fields. Installed at the panel, the device works passively on the active power flowing through the system, smoothing current waveforms, reducing harmonic distortion, and suppressing electrical noise without interrupting operation.

In a 24/7 facility these effects compound. Because the load never rests, the device is working every hour of every day, and no change to how the facility operates is needed. The device also reduces heat, noise, and vibration in power distribution equipment, which supports longer service life for panels and connected loads. With a product life of more than ten years and no moving parts or consumables, it keeps delivering these benefits with minimal maintenance.

Results: What Port Operators Should Measure

ENPOSS's officially documented performance figures for the FORCE ESD are a 5 to 15 percent reduction in power usage, depending on the facility's load profile and tariff structure. These figures come from performance testing and field installations across commercial and industrial environments, including the port and logistics sector. Results also vary with operating hours and measurement period. They apply only to the samples and conditions that were tested and are not guaranteed for every installation. The reliable approach is to measure against a baseline at your own site.

On a 500 kW system running twenty-four hours a day, any confirmed reduction repeats every hour because the baseline consumption is always active. For a port operator, a confirmed reduction in electricity spend would be a direct, recurring improvement to operating cost, and a lower power draw would also support the carbon reporting and sustainability commitments that increasingly accompany port operations.

Test and inspection documents from independent organizations exist for FORCE ESD. Each one is limited to the samples, sites and conditions it covers, so ask ENPOSS for the specific documents and check what each covers before relying on it.

Assess Energy Savings at Your Own Facility

Port authorities, terminal operators, and logistics facility managers evaluating energy efficiency measures can follow the same path taken in this case study: a site assessment to establish the facility's load profile, a correctly sized FORCE ESD installation at the main panel, and measurement against the pre-installation baseline to verify results.
