EPC expertise, renewable enthusiasts

Utility-scale renewables, end-to-end

INZAG has decades of experience delivering complex infrastructure, alongside utility-scale renewable energy projects with a combined capacity of over 4 GW.

We act as a single integrated EPC and O&M contractor across solar PV, battery energy storage, wind and hydropower, controlling the project from feasibility through commissioning and long-term operations.

Currently active in Portugal, Spain, Ireland and Germany, with more than 5 GW of additional capacity in negotiation.

One contracting partner, flexible models, complete project lifecycle

Build phase
EPC
Engineering, Procurement and Construction under one contract, including Balance of System (BoS) and Balance of Plant (BoP).
Operate phase
O&M
Predictive and corrective maintenance, plus dispatch monitoring across the asset lifecycle.

Technologies we deliver

Solar PV
Utility-scale ground-mount photovoltaic plants, grid feasibility through commissioning. Engineered to European IPP standards.
BESS
Standalone and co-located battery storage. AC-coupled retrofits of existing PV and wind sites without host-plant redesign.
Wind
Onshore wind farm engineering and construction, integrated with substation and grid-connection scope.
Hydro
Conventional and pump-storage hydropower, drawing on +38 GW of hydropower construction heritage.
