GreenVolt

What GreenVolt does

GreenVolt Group is a Portuguese multinational renewable energy developer and operator listed on Euronext Lisbon (ticker: GVOL) and headquartered in Lisbon, with KKR as a controlling shareholder following a $6.4 billion combined commitment into Greenvolt and Encavis AG. The company operates three business segments — Biomass (its original business using agricultural and forestry residues), Utility-Scale (Greenvolt Power, covering wind, solar PV, and grid-scale battery energy storage), and Distributed Generation (Greenvolt Next, serving commercial and industrial clients with rooftop and ground-mounted solar across the UK, Ireland, and Germany). Underlying technologies span LFP-based battery storage systems, onshore wind (using GE Vernova 6.1 MW turbines in Romania), and solar PV, with projects developed to ready-to-build or operational status.

The business model is a hybrid of project development with equity recycling and contracted revenue. Greenvolt originates and develops utility-scale projects, secures non-recourse project finance from bank consortiums (e.g., EUR 348m for Romania wind, EUR 58.9m for Hungary BESS), and sells operational or near-ready assets to strategic buyers such as ENGIE Romania, Enea, and Nuveen Infrastructure, generating capital gains that are redeployed into the pipeline. Parallel revenue streams include long-term government-backed revenue contracts (10-year CfDs, 15-year TERNA capacity contracts in Italy), C&I solar installation fees with ongoing O&M, biomass generation, and green bond issuance (EUR 170m to date). The company manages a 12.8 GW probability-weighted development pipeline including 5 GW of BESS, operates across 12+ European countries, and runs dedicated subsidiaries including Greenvolt Power, Greenvolt Next UK, Greenvolt Next Ireland, and a 51% stake in Spanish BESS developer Ibersun Generación.

Revenue model

1. Project Development and Equity Sales: Greenvolt develops utility-scale renewable energy projects (wind, solar, BESS) through its development pipeline. Completed or operational projects are sold to strategic buyers, institutional investors, or energy companies, generating capital gains and recycling equity into new development projects.
2. Long-term Government-backed Revenue Contracts: BESS projects earn revenues under 10-year CfD (contract-for-difference) or cap-and-floor contracts awarded via public auctions. After contract expiry, projects participate in merchant electricity markets.
3. Distributed Generation (C&I Solar): Greenvolt Next installs solar panels and systems for commercial and industrial clients (retail, logistics, manufacturing), generating revenue through project development and installation fees, with ongoing O&M relationships.
4. Green Bond Financing: Greenvolt raised EUR 170 million through green bond issuances (Green Bonds 2024-2029), with proceeds supporting renewable energy growth and utility-scale project expansion.

Core offering

GreenVolt develops, finances, builds, and operates renewable energy assets across three business segments: biomass power generation, utility-scale wind/solar PV and battery energy storage (Greenvolt Power), and distributed rooftop/ground-mounted solar for commercial and industrial clients (Greenvolt Next). The company develops projects through a 12.8 GW pipeline, secures project finance from bank consortiums, and either sells completed projects to strategic buyers or holds them to earn long-term contracted revenue via contract-for-difference (CfD) auctions.

Product overview

Greenvolt Group is a Portuguese renewables company delivering 100% green power through multiple technologies across several geographies. The company operates through three core business segments: Biomass (organic material-based power generation), Utility-Scale (large wind and solar farms plus battery storage), and Distributed Generation (commercial rooftop solar). The main operating units include Greenvolt Power (utility-scale wind, solar, and BESS development) and Greenvolt Next (distributed solar for commercial/industrial clients in the UK and Ireland). Recent major projects include the 99.8 MW/288.6 MWh Buj BESS in Hungary (largest operating storage in the country), wind projects in Romania (253 MW Ialomița), and hybrid solar-plus-storage in Denmark. The company has a probability-weighted development pipeline of 12.8 GW including 5 GW of battery storage.
