What Green Capital does

Green Capital S.A. is a privately held company headquartered in Warsaw, Poland, operating an integrated platform that combines utility-scale renewable energy generation with digital infrastructure engineering for AI and high-performance compute workloads. The company develops and operates utility-scale wind and solar renewable energy systems, battery energy storage (BESS) assets, and high-performance computing / data center infrastructure, and reports an operational footprint spanning 13 countries with 77 completed projects, 700+ MW in operational renewables, and pipelines of approximately 50 GW in BESS and 29 GW in data center IT capacity.

The platform is built around two flagship projects: the Atlas Giga Hub — a 12 GW advanced compute portfolio with an inaugural 6 GW facility in Patagonia (Argentina/Chile) launched in 2025 and engineered to achieve an ultra-efficient Power Usage Effectiveness (PUE) of 1.04 by leveraging Patagonia's wind resources and natural cooling — and a 414 MW BESS platform across multiple locations in Poland, supported by long-term capacity contracts and scheduled for grid connection in H1 2027. Green Capital positions itself as a vertically integrated 'Green Compute Provider' in which power generation, storage, and compute capacity are designed to scale together.

Green Capital generates revenue through long-term power purchase agreements (PPAs) and capacity contracts with grid operators and utilities (recurring), AI infrastructure development agreements and colocation contracts with AI companies and digital infrastructure operators (managed services), and BESS capacity contracts for grid stabilization and energy arbitrage. The company sells through direct enterprise sales to institutional clients and governments, with no public pricing tiers and project-specific, long-cycle negotiations. Primary customer segments are AI infrastructure operators and digital infrastructure companies, with grid operators and utilities as a secondary segment. Notable data gaps include undisclosed revenue, funding history, ownership, founders, and management team.

Revenue model

1. Contract-Backed Power Generation: Green Capital develops and operates utility-scale renewable energy and storage assets, delivering stable, contract-backed power across multiple markets. Revenue is generated through long-term power purchase agreements (PPAs) and capacity contracts with institutional customers.
2. AI Infrastructure Services: The company designs and builds high-performance digital infrastructure engineered for large-scale AI and advanced compute. Revenue is generated through infrastructure development agreements, long-term colocation contracts, and operational partnerships with AI companies and digital infrastructure operators.
3. Energy Storage Capacity Contracts: The 414 MW BESS platform is supported by long-term capacity contracts with grid operators, providing recurring revenue for grid stabilization services and energy arbitrage.

Core offering

Green Capital operates an integrated platform that develops and operates utility-scale renewable energy assets (wind and solar) and battery energy storage systems (BESS), and designs, builds, and operates high-performance digital infrastructure (AI-grade data centers) for institutional and enterprise clients. Power generation, storage, and compute are delivered under a single vertically integrated model so that electricity and AI compute capacity scale together, exemplified by the Atlas Giga Hub portfolio (12 GW) and the 414 MW BESS Platform in Poland.

Product overview

Green Capital operates as an integrated platform combining two core capabilities: Renewable Energy Systems and AI Infrastructure. The Renewable Energy Systems component develops and operates utility-scale renewable energy and storage assets delivering contract-backed power across markets. The AI Infrastructure component designs and builds high-performance digital infrastructure for large-scale AI and advanced compute. These capabilities are delivered through flagship projects including the Atlas Giga Hub portfolio (12 GW advanced compute platform, with first 6 GW facility in Patagonia achieving PUE of 1.04) and the 414 MW BESS Platform in Poland. The platform enables power and compute to scale together through vertical integration.

Direct peers

• Crusoe Energy: Crusoe builds large-scale data centers for AI training and inference co-located with energy resources (initially flared gas, now increasingly renewables). It is the closest publicly known competitor pursuing a vertically integrated 'compute co-located with cheap/clean energy' thesis at GW scale.
• CoreWeave: CoreWeave is an AI-focused cloud provider that has grown into a vertically integrated platform owning and operating its own GPU data centers with secured power. It competes for the same AI infrastructure customer base that Green Capital targets with its integrated compute-plus-energy offering.
• Talen Energy: Talen Energy pairs nuclear and large-scale generation with co-located data center campuses (Susquehanna), giving AI customers dedicated, low-carbon power. It is a clear directional analogue for the 'power and compute under one owner' model Green Capital is pursuing.

Emerging players

• Prometheus Hyperscale: Prometheus Hyperscale is building sustainable, large-scale AI data centers across Europe, including in Poland. It targets the same institutional AI infrastructure buyer and overlaps directly with Green Capital's Polish and broader European footprint.
• Lambda: Lambda operates GPU cloud and is investing in owned/operated AI data center capacity. It pursues a vertically integrated AI infrastructure model and competes for the same AI compute customers Green Capital is courting with its renewable-powered facilities.

Broad incumbents

• Fluence Energy: Fluence is a global BESS OEM and integrator delivering utility-scale battery storage systems, software, and services. It directly addresses Green Capital's BESS integration and operations stack as a competitor supplier in the same value chain.
• Wärtsilä Energy Storage: Wärtsilä designs, integrates, and operates utility-scale BESS and grid-scale storage assets globally. It is a comparable incumbent that competes for European utility-scale BESS deployment contracts analogous to Green Capital's 414 MW Poland platform.
• Vantage Data Centers: Vantage is a large, well-capitalized wholesale colocation and hyperscale data center developer with a global footprint. It competes for the same AI infrastructure customers that Green Capital targets with its vertically integrated renewable-powered data centers.
• Stem Inc: Stem provides AI-driven energy storage and asset performance software plus integrated BESS solutions for utilities and developers. It is a comparable incumbent whose BESS software and integration services overlap with Green Capital's storage operational stack.

Others

• DigitalBridge: DigitalBridge is the leading alternative asset manager focused on digital infrastructure (data centers, towers, fiber). It is a natural capital partner and competitor for institutional capital seeking exposure to AI compute infrastructure of the kind Green Capital is developing.
