Sectors

Built for the renewable grid.

Transformers for solar, BESS, and wind generation - onshore, offshore, and grid-tie.

Britain's energy mix has changed. Embedded generation, distributed storage, and offshore wind now make up a significant share of the network - and the transformer apparatus connecting that generation to the grid has had to evolve with it.

We work with renewable developers, EPC contractors, and asset operators on every transformer between the generator and the grid - from kiosk-mounted distribution units for rooftop solar developments to step-up transformers for utility-scale offshore wind. Variable load profiles, harmonic content, fast cycling duty, and grid-code compliance are all designed in from the start.


Solar & BESS

Solar, storage, grid-tie.

Solar collector transformers

Designed for variable load profiles and inverter-driven harmonic content. Compact corrugated-wall designs up to 8.5 MVA. Single and dual-inverter connections.

Inverter step-up duty, BESS connection, and grid-tie at the substation - designed for the modern renewable inverter network.


BESS interface transformers

Bidirectional power flow. Fast-cycling duty. K-factor compatibility for non-linear loads. Engineered for modern lithium-ion storage topologies.


Substation step-up

Collector voltage to grid voltage. Conservator or sealed-hermetic designs. Ester or silicone oil options for environmentally sensitive sites.


Grid-tie connection

Interface to DNO connection points. ENA G99-compliant designs available. ANM-compatible for active network management schemes.

Wind

Onshore. Offshore. Nacelle.


Wind turbine transformers

Nacelle-mounted units engineered to withstand high vibration levels. KFAF / KFWF cooling to reduce footprint. Custom designs to suit each nacelle configuration.

From nacelle-mounted dry-types to offshore substation transformers - the full chain from turbine to grid connection.


Park collector transformers

Aggregation at the wind farm substation. Multi-feed designs for collector circuits. Conservator and sealed designs.


Offshore substation

Marinised designs for offshore wind farm substations. Salt-spray and corrosion protection. Reduced-maintenance specifications.


Export transformers

High-voltage step-up to grid connection. Engineered to grid-code requirements with witness-tested performance.

Engineering practice

Designed in. Witness-tested.

Renewable connections sit in a tighter compliance envelope than legacy grid apparatus. Every unit is designed to it.


Standards

IEC 60076, EN 50588, EU Ecodesign Tier 2, ENA G99 (where applicable)


Grid compliance

ANM-compatible designs. Witness-tested in accordance with grid-code requirements.


Loss optimisation

Loss capitalisation modelled across the project life. Amorphous-core options on distribution units.


Insulation fluids

Mineral oil standard. Ester or silicone fluids available for environmentally sensitive sites.


Tap changing

OLTC and DETC options across the range. On-load regulation for fluctuating generation profiles.
