OUR JOURNEYEstablished in 2022, Helios has grown into a multi-country EPC and Sub-EPC partner with 14 completed projects,
more than 716 MWp of solar capacity delivered and over 1.5 GW of wind, solar and battery storage under execution across Europe.
Established in Romania, first utility-scale solar deliveries (Rateşti SPP, 154 MWp).
Growing operations in Central Europe; Oradea and Parau SPPs delivered in Romania.
Expanding into Southern Europe; six Romanian solar parks completed in one year.
First wind (Tulucesti-Foltesti, 162.4 MWm) and first battery storage (Parau BESS, 156 MWh) projects.
Kremena-Trigortsi WPP in Bulgaria and The Minety Stonehill BESS in the United Kingdom.
AT THE CORE OF ENERGY
Projects Completed
Helios was founded by a team with three decades of hands-on experience in heavy civil works and renewable energy construction, from wind turbine foundations and access roads to substations and transmission lines. That field discipline is the backbone of everything we deliver today.
We take command of the entire infrastructure process, access roads through impenetrable terrains, large-scale crane platforms, reinforced concrete foundations, PV mounting and cabling, BESS foundations, switchyards and transmission lines, as an EPC and Sub-EPC partner offering a single point of responsibility from survey to turnkey delivery.
Established in Romania in 2022, Helios rapidly expanded its footprint to Hungary, Italy, Bulgaria and the United Kingdom, delivering more than 716 MWp of utility-scale solar and taking on the latest frontier of energy technology with over 1 GWh of Battery Energy Storage Systems under execution across Europe.

Sustainability
THE HELIOS STANDARDFor us, construction is never just about concrete and steel. From geotechnical surveys to structural calculations, we manage every stage
of the project based on sound engineering data, executed on site with speed, precision, and without unnecessary delays.
We make our decisions not on assumptions, but on the analyses and engineering calculations produced by our technical office.
We do not wait for problems to arise; we anticipate them in advance and deliver solutions before they occur.
Instead of cumbersome bureaucracy, we operate with a fast, agile, and results-oriented decision-making process.
Our clients can monitor both the technical and financial progress of the project in real time, with full transparency.
We collaborate with leading renewable energy developers, EPCs and technology providers across Europe
