SHORE POWER

The Shore Power Energy Storage System is abattery storage solutioncustomized by HMT for port vessel berthing power demand. By deploying LT-C1 containerized battery systems (or multiple LT-S1 units in parallel) at the dock, it charges during off‑peak grid hours and discharges when vessels connect to shore power. This reduces the port’s peak transformer load, lowers upgrade costs, and generates revenue through peak‑to‑off‑peak price arbitrage. This is aproject‑based business , fully customized to the port’s berthing capacity, vessel types, and power conditions.

Advantages

Plug‑and‑play shore power storage based on LT-C1 containerized batteries. Reduce transformer upgrade costs and smooth grid load.

Reduce transformer upgrade costs

Peak shaving minimizes dependence on grid expansion, saving millions in upgrade fees.

Peak‑off‑peak arbitrage

Charge at low night rates, discharge during daytime vessel berthing at higher rates, accelerating ROI.

Plug & play

LT-C1 containerized design, factory assembled and tested, ready to power after on‑site lifting.

Highly scalable

Add LT-C1 containers as needed to match future port expansion.

Grid support

Provides ancillary services such as reactive power compensation and frequency regulation, improving port grid stability.

Remote monitoring & O&M

Cloud platform real‑time monitoring of SOC, SOH, charge/discharge status, supporting unattended operation.

System Components

Energy storage unit

LT‑C1 containerized battery system (20ft/40ft), 500kWh~2MWh per container, multiple parallel.

Bidirectional PCS

AC/DC conversion, grid‑tied or island mode, 100kW~1MW power options.

Energy management system (EMS)

Real‑time monitoring of load, grid, battery SOC; automatic charge/discharge control; remote access.

Shore power interface cabinet

Includes breaker, metering, communication; compatible with IEC/IEEE shore power standards.

Why Choose HMT for Shore Power

Marine‑grade reliability

Designed to class society standards, tested for salt spray, vibration, temperature/humidity cycles – suitable for harsh port environments.

Modular scalability

From 500kWh to tens of MWh, parallel as needed, flexible investment.

Intelligent EMS

In‑house algorithms supporting peak‑valley arbitrage, demand management, island operation, etc.

Fast deployment

Containerised design, factory pre‑assembled, only lifting and electrical connection on site; operational in 3–5 days.

Applications

Old port with insufficient transformer capacity

New shore power load exceeds transformer; upgrade cost prohibitive

Fishing port with night concentrated charging

Many fishing boats charging simultaneously at night, causing grid impact

Cruise terminal with multiple simultaneous berths

Single berth consumption10 MWh, requires large buffer

Island port with weak grid

Low grid capacity, severe voltage drop when vessels connect

4 Wheel Electric Forklifts are an important piece of equipment for many industrial and commercial settings. They can help to move heavy objects quickly and easily, without the need for a lot of manual labor. There are a variety of different electric forklifts on the market, but one of the most popular types is the 4 wheel electric forklift. This type of forklift is especially useful for moving large objects around tight spaces. It can also navigate easily over bumps and uneven surfaces.
