go4green

What go4green does

go4green is a Brussels-based energy services company founded in 2009 that finances, installs, and operates cogeneration (combined heat and power) units and photovoltaic solar panels for residential collective buildings, principally co-ownership associations (ACP/VME), public social housing companies (SISP/OPM), and selected real estate developers in the Brussels-Capital Region. Its core technology stack is centered on natural-gas-fired CHP modules sized to building demand (typically 15–50 kWe), paired with rooftop PV systems and supported by professional monitoring and maintenance.

The company's commercial model is a third-party investment (tiers-investisseur) structure: go4green bears 100% of the project capex — typically €100,000 to €300,000 per site, financed via its own capital and bank loans — and recovers the investment over a 10-year contract through the sale of Brussels-Region green electricity certificates (certificats verts) and the resale of surplus electricity to the grid, sharing a portion of profit with the building. Building owners pay nothing upfront and bear no operating costs during the contract; PV systems transfer for a symbolic €1 at maturity.

Go4green goes to market through direct enterprise field sales targeting building decision-makers (co-ownership general assemblies, SISP boards, property syndics), supplemented by strategic channel partnerships with property managers such as TREVI and developer partnerships with Home Invest Belgium. As of 2018–2019 the company reported more than 100 active installations, cumulative project investment above €15 million, and nearly 2 MW of installed electrical capacity in Brussels. Reported customer outcomes include 10–45% CO2 reductions per building and ten-year financial gains to occupants of €20,000–€240,000 depending on site size.

Revenue model

1. Green Electricity Certificate Sales: go4green monetizes its installations by selling green electricity certificates (certificats verts) granted by the Brussels Region for cogeneration and photovoltaic energy production. These certificates are the primary revenue stream funding the company's third-party investment model.
2. Grid Electricity Resale: Surplus electricity produced by cogeneration units and photovoltaic panels that is not consumed by the building is sold back to the electricity grid, generating additional revenue beyond green certificates.

Core offering

go4green finances, installs, and manages natural gas cogeneration units and photovoltaic solar panels on collective residential buildings in Brussels at no cost to the building owner, under 10-year third-party investment contracts. Revenue is generated by monetizing green electricity certificates issued by the Brussels Region and by reselling surplus electricity back to the grid, with remaining profits shared roughly one-third with the co-ownership. The company also delivers free energy audits and feasibility studies as the entry point of its sales process.

Direct peers

• Enora: French ESCO specializing in residential and collective-building cogeneration under a third-party-investment model. Closely comparable to go4green in customer profile (co-ownerships, social housing), technology (CHP units), and revenue model (selling electricity/heat to the building and monetizing public support schemes).
• Dalkia (EDF group): Large French ESCO operating district heating and cogeneration networks, including residential and collective-housing customers. Comparable in core CHP/energy-efficiency offering, though at materially larger scale and with broader municipal and industrial exposure.

Broad incumbents

• EDF Luminus: Belgian energy supplier and generator providing residential energy solutions and green tariffs in Brussels. Comparable customer base (residential/collective housing) and geography, but operates as a broad retail supplier rather than a CHP specialist.
• Luminus: Major Belgian energy retailer and generator (EDF affiliate) with residential services in Brussels including solar, heat pumps and energy efficiency offerings. Overlaps with go4green on residential energy services in the same geography but does not specialize in CHP third-party-investment.
• Engie Electrabel: Dominant incumbent Belgian utility offering residential cogeneration, solar, and energy efficiency services across Belgium including Brussels. Competes for the same ACP/VME and social housing customers but as part of a broader utility portfolio rather than a niche specialist.
• Eneco Belgium: Dutch-Belgian sustainable energy retailer with residential solar and heating offerings in Brussels. Adjacent customer base and sustainability positioning, though Eneco's CHP exposure in Belgium is limited.

Emerging players

• Aspiravi: Belgian renewable energy developer focused on wind and solar with growing presence in Brussels/Brabant. Comparable in building green-generation assets in Belgium but does not currently specialize in residential cogeneration or third-party-investment for co-ownerships.
• Nethys (RESA / Elicium): Belgian energy group (parent of RESA grid and energy service businesses) with activity in energy efficiency and renewables. Comparable as a Belgian energy player expanding into distributed energy services, though headquartered in Wallonia rather than Brussels.
• IZEN (Elicium): Belgian solar installer and ESCO focused on residential and SME solar PV in Brussels and Wallonia. Overlaps with go4green on the PV side of the offering and on third-party-financed installations for buildings.

Others

• TREVI Group: Large Belgian property management (syndic) firm and go4green's channel partner. Relevant as the ecosystem that originates customer leads for go4green and a representative example of the syndic firms through which go4green distributes its service.
