01

Grid-Side EnergyStorage

150MW / 300MWh

Problem

Grid operators managing high volumes of renewable generation face volatility that conventional dispatch cannot smooth on its own, along with peak-shaving pressure as demand rises at the edges of the network.

Approach

A grid-side battery energy storage deployment absorbs excess generation and discharges it back during periods of peak demand, acting as a buffer between variable supply and the load the network needs to serve.

Scope

A 150MW / 300MWh grid-side storage installation, engineered and manufactured from our containerised energy storage product line and integrated with the grid operator's dispatch requirements.

02

Industrial MicrogridStorage

690kW / 1,398kWh

Problem

An industrial site with significant peak demand charges and uneven load across the day needed a way to reduce electricity costs without altering its production schedule.

Approach

A microgrid-scale battery energy storage system performs peak shaving and valley filling — discharging during high-tariff periods and recharging during low-demand periods — reducing the site's exposure to peak tariffs.

Scope

A 690kW / 1,398kWh industrial microgrid storage system, drawn from our AI-managed storage unit product line and integrated with the site's existing electrical infrastructure.

03

Underground TransformerProgramme

IP68

Problem

A major cross-sea bridge, tunnel and island infrastructure programme required power equipment that could operate reliably underground and in marine-exposed conditions, where conventional transformer enclosures are unsuitable.

Approach

IP68-rated, amorphous-alloy transformers designed for buried installation delivered the required protection against water ingress and corrosion while meeting the programme's efficiency requirements.

Scope

Supply of IP68 underground transformers across the bridge, tunnel and island sections of the programme, manufactured to the amorphous-alloy specification used across our grid equipment range.
