Built on time, on budget and to the highest standards

The construction phase is where careful planning turns into a working power plant, and where experience makes the biggest difference.

In practice

We are currently building the first Enercon E-160 in Bulgaria near Balchik, fully hybridised with 11.41 MWh of storage, and in 2026 we added battery storage to three operating wind sites.

With more than 18 years of experience in building wind, solar and battery storage projects, Ventus gives clients and partners a reliable, hands-on partner from groundbreaking to commissioning.

On site

Full responsibility, precise coordination

We manage every phase of construction with precision and a clear focus on results. Our senior core team leads each project on site, supported by a trusted network of experienced contractors and specialist partners. Together, we plan and sequence the work, supervise progress on site and carry out all checks and tests until the plant is fully ready for operation. Three priorities guide everything we do: completion on schedule, strict budget control and first-class technical quality.

A successful build depends on many parties working together smoothly. We coordinate grid operators, independent experts, contractors and suppliers, public authorities and landowners, so everyone is aligned and the project moves forward without unnecessary delays.

Our own projects

Experience from our own projects

The expertise we offer our clients comes directly from building our own wind, PV and BESS portfolio in Bulgaria and Spain. We know the technical, regulatory and practical challenges of construction in these markets, and we know how to solve them efficiently.
