Green Enesys

What Green Enesys does

Green Enesys Group GmbH is a Swiss-headquartered international renewable energy project developer founded in 2009, operating from offices in Baar (Switzerland), Berlin (Germany), Madrid (Spain), and Campodarsego (Italy). The company develops utility-scale photovoltaic, agrivoltaic, battery energy storage (BESS), thermal energy storage, e-methanol, and green hydrogen projects from origination and permitting through financing, then sells ready-to-build or ready-to-finance assets to energy companies, infrastructure investors, and industrial off-takers. Its core technology suite combines proprietary project integration capabilities with the bGen crushed-rock thermal storage system from Brenmiller Energy and the SolWinHy Cádiz off-grid e-methanol configuration (130 MW PV + 54 MW wind + 80 MW electrolyzer).

The company operates a multi-stream revenue model: one-time project development and asset sales via SPAs (exemplified by transactions with Axpo and Pulse Clean Energy), managed thermal energy services through a 15-year Thermal Energy-as-a-Service model with eventual system transfer to customers, equipment sales of bGen systems, and future production-based revenue from green hydrogen and e-methanol. Green Enesys goes to market through direct enterprise field sales to landowners, municipalities, large-scale investors, and industrial customers (food and beverage, chemicals, mining), supplemented by crowdfunding channels (Ener2Crowd) for retail investor participation in PV projects.

Key customers and partners include Axpo (repeat SPA counterparty for Agata, Zafiro PV and Neunburg BESS), Pulse Clean Energy (UK BESS), Tempo Beverages/Heineken (thermal storage), Viridi RE (long-standing co-development partner for 12+ GW of pipeline), Brenmiller Energy (thermal storage technology), and H2Global Foundation (founding member). The company has delivered approximately 500 MWp of renewable energy and sold over 1 GW of projects in the trailing 18 months, with a 12 GW development pipeline across 15 countries and a 2030 production target of 345,000 tons of e-methanol and 70,000 tons of green hydrogen.

Revenue model

1. Project Development and Sale: Green Enesys develops utility-scale renewable energy projects (PV, BESS, thermal storage) from origination through permitting and financing, then sells ready-to-build or ready-to-finance projects to investors and energy companies. Revenue is realized through project sales, SPA (Sale and Purchase Agreement) transactions, and development fees.
2. Thermal Energy as a Service: Turnkey thermal energy service providing businesses with sustainable heat solutions including installation, financing, operation, maintenance, and energy trading. After 15 years, the system transfers to the customer at no additional cost. Revenue generated through long-term energy service contracts.
3. Equipment Sales: Sale of thermal energy storage systems (bGen) and associated equipment to industrial customers seeking to electrify heat applications.
4. E-Methanol and Green Hydrogen Production: Production and sale of green hydrogen and e-methanol for sustainable shipping, industrial applications, and transport sectors. The SolWinHy Cádiz facility is expected to produce 29,000 tons of e-methanol annually, with negotiations underway with German off-takers.

Scale indicators12 records

Recent moves6 records

Expansion highlights6 records

Emerging players

• Everfuel: Green hydrogen producer/developer building electrolyzer and e-mobility infrastructure across Europe. Comparable for green H2 production and Power-to-X commercialization, though Everfuel focuses more narrowly on H2 distribution and mobility vs. Green Enesys' broader portfolio.
• Copenhagen Infrastructure Partners (CIP): European renewable infrastructure fund manager with major green hydrogen and Power-to-X platforms (e.g., Fund for industrial-scale H2). Directly comparable as an investor/developer in green H2 and e-methanol projects in Europe; CIP typically has more capital but lighter development depth outside wind.

Direct peers

• Akuo Energy: Independent renewable developer active in PV, wind, storage, and green hydrogen across Europe with a similar project development and PPA origination profile. Closely comparable as an integrated renewables developer with European mid-market scale.
• Sonnedix: Listed as Green Enesys partner; global independent solar power producer with European IPP focus. Comparable in PV + storage project development, scale, and European operating geographies, even though Sonnedix typically holds assets rather than selling RTB.
• Lightsource bp: Global solar and storage developer with strong utility-scale PV and BESS project pipeline in Europe. Directly comparable RTB/RTF project sale model and European geography, though substantially larger and bp-backed.
• BayWa r.e. European-headquartered developer of utility-scale solar, wind, and storage projects with a develop-to-sell model and active trading arm. Closely comparable in technology stack (PV, BESS, agrivoltaic) and European project origination footprint.
• Viridi RE: Green Enesys' core strategic co-developer across PV, BESS, green hydrogen and e-methanol; explicitly comparable because of joint JV structures (Brenmiller Europe, One Planet Developments) and overlapping 12 GW-plus pipeline. Operates as a parallel renewable developer with shared risk and reward.
• Aquila Capital: Listed as a Green Enesys client/partner; Hamburg-based developer and asset manager of wind, solar, and BESS across Europe. Comparable as a developer-investor hybrid developing renewable assets then retaining/operating them with investor capital.

Broad incumbents

• Statkraft: Europe's largest renewable energy generator and a leading European developer/operator of hydro, wind, solar, and BESS. Broad incumbent with overlapping origination, M&A, and PPA activities, though much larger and asset-heavy.
• Encavis AG: German-listed operator/developer of solar and wind parks across Europe. Overlapping IPP-style renewables business with European footprint; comparable for renewable project acquisition (BESS, PV), though Encavis primarily acquires from developers like Green Enesys rather than originating at parity scale.
