Helios Ventures is an Amsterdam-based developer and investor in utility-scale solar, battery storage, digital infrastructure and green hydrogen across the Netherlands, Romania, Italy, Spain and Türkiye.
02 About Helios
Helios Ventures B.V. originates, develops and finances renewable energy infrastructure — from greenfield solar parks and grid-scale battery storage to sustainable data centres and green hydrogen. We combine hands-on development capability with disciplined, institutional-grade investment.
Our team has built and exited renewable platforms across two decades, operating today through a network of project companies and strategic holdings spanning Western Europe, South-Eastern Europe and Türkiye. We invest our own capital alongside co-investors, development finance institutions and strategic partners.
We co-invest our own equity in every transaction — aligned, not arm’s length.
03 What We Do
Greenfield and operating PV parks, developed to ready-to-build and held through construction and operation.
Grid-scale BESS — standalone and co-located — capturing arbitrage, grid services and capacity revenue.
Sustainable digital infrastructure powered by on-site renewables and storage, including sovereign-grade nodes.
Electrolysis-based hydrogen and energy storage as a long-duration complement to our power assets.
04 Where We Operate
The Netherlands is undergoing aggressive grid expansion and storage mandate rollout. We focus on solar PV and grid-scale BESS assets where SDE++ subsidy frameworks and grid operator relationships create investment certainty.
Romania offers among the highest solar irradiation in Central Europe with land availability, competitive development costs, and a rapidly maturing regulatory framework. We operate as direct equity investors and local development partners.
Italy combines strong solar irradiation with accelerating storage demand and a supportive capacity-market framework. We pursue solar PV and co-located storage development across high-value grid zones.
Spain offers some of Europe’s most competitive solar economics, deep grid capacity and a maturing storage market. We focus on utility-scale solar and hybrid storage in regions with strong resource and offtake fundamentals.
Türkiye's geography creates rare opportunities in secure, energy-efficient digital infrastructure, alongside an operating renewable portfolio. Our Turkish operations focus on sovereign-grade data infrastructure where location and structural advantages create durable competitive moats.
05 Pipeline & Track Record
06 Our Thesis
As solar and wind penetration increases, grid stability requires dispatchable storage. Battery energy storage systems are transitioning from ancillary service providers to core infrastructure — and the investment window for development-stage BESS is open now.
Romania, Türkiye, and similar markets offer structurally attractive renewable development economics that pan-European funds cannot efficiently access. Direct equity investors with on-the-ground relationships capture development margin that arms-length capital cannot.
AI-driven compute demand and national data sovereignty requirements are creating demand for secure, energy-efficient digital infrastructure in locations that cannot be replicated. First-mover positioning in the right geographies creates durable competitive moats.
Beyond our own development pipeline, Helios Ventures invests as a limited partner and financial investor in companies advancing clean energy, advanced electronics and industrial intelligence — backing strong teams across our core markets.
