Sectors

Where our cabinets make the difference.

We partner with utilities, EPCs, IPPs and heavy industry on projects where execution, certification and traceability are non-negotiable.

01

Utility & TSO/DSO

Secondary substations, network upgrades, point-of-connection. Compliant with Endesa, REE, Iberdrola, EDP, National Grid.

02

Renewables

Skids for solar PV plants and wind farms. BESS integration for time-shifting, peak shaving and arbitrage.

03

Industry & data centres

Redundant e-Houses, mission-critical power, N+1 architectures. Civil works cut by up to 60%.

04

Mining & oil & gas

Rugged platforms for harsh environments — extreme temperatures, dust, ATEX zones.

05

e-Mobility

Cabinets for ultra-fast charging hubs with integrated storage, avoiding costly grid reinforcement.

06

Agri & desalination

Plug & play substations for pumping stations, irrigation and desalination plants. Remote operation, low maintenance.

Why Evocabin

European engineering, industrial execution.

We're not assemblers. We design in BIM, manufacture in a controlled production line, fully test before shipping and deliver with documentation ready for utility inspection.
