Greenergy

What Greenergy does

Greenergy is a privately held Hungarian renewable energy company that develops and operates projects across multiple clean energy technologies, including solar, wind, bioenergy, and energy storage. Founded in 2002 and headquartered in Budapest, the company has accumulated over two decades of operational history in the Central European energy market, positioning it as an established mid-sized player in Hungary's renewable energy sector.

The company's core activities span the full project lifecycle — from development and permitting through construction to ongoing operations of renewable generation and storage assets. Its technology stack is diversified across solar photovoltaic, wind generation, bioenergy (biomass/biogas), and energy storage systems, suggesting a portfolio approach to capturing different generation profiles and grid services rather than specialization in a single technology. The company's Hungarian website (.hu domain) confirms its primary operating geography.

Greenergy's business model appears to be that of a project developer and independent power producer/operator, generating revenue through the sale of electricity, capacity, and ancillary services from owned and operated renewable assets, as well as potentially through development fees and asset management. With 51-100 employees, it operates at a scale typical of mid-market European IPPs that balance in-house development with outsourced construction and EPC services. The company remains private and has not pursued public capital markets.

Core offering

Greenergy develops and operates renewable energy and energy storage projects, including solar, wind, and bioenergy assets. As an integrated developer/operator, it plans, builds, owns, and runs generation infrastructure producing electricity supplied to grids, utilities, and industrial buyers. The energy storage portfolio provides firming and balancing capability for intermittent renewable generation.

Products and services

• Solar power generation projects Utility-scale or distributed solar PV power generation projects developed, built, and operated by Greenergy, delivering renewable electricity to grid/utility offtakers under PPAs, feed-in tariffs, or regulated schemes.
• Wind power generation projects Wind energy generation projects developed and operated by Greenergy, producing electricity for sale to utilities, corporates, or wholesale markets under long-term offtake arrangements.
• Bioenergy generation projects Bioenergy (biomass/biofuel-based) power generation projects operated by Greenergy, providing dispatchable renewable electricity from organic feedstocks.
• Energy storage projects Energy storage infrastructure (battery or equivalent) deployed alongside or paired with Greenergy's renewable generation assets to firm output, balance intermittency, and provide ancillary grid services.

Broad incumbents

• Enel Green Power: Global renewable energy developer-operator with wind, solar, geothermal, and storage capacity. Comparable to Greenergy's multi-technology developer-operator model at a global scale.
• Iberdrola Renovables: Global renewable energy developer-operator with significant European wind, solar, and storage pipeline. Comparable to Greenergy as a developer-operator but at vastly greater scale and geographic diversification.
• MVM Group: Hungarian state-owned energy group with growing renewable and conventional generation. Comparable as a domestic Hungarian energy operator, though at vastly greater scale and with broader scope than Greenergy.
• Engie: Multinational utility with a major renewable energy and battery storage development arm across Europe. Comparable as a broad incumbent that develops and operates renewable and storage assets in markets overlapping with Greenergy.
• RWE Renewables: Major European renewable energy developer with onshore/offshore wind, solar, and battery storage projects. Comparable as a multi-technology renewable developer competing in the same broader European market as Greenergy.
• EDP Renováveis: One of the world's largest wind and solar developers with strong European presence. Comparable as a multi-technology renewable IPP, though operating at far greater scale than Greenergy.

Direct peers

• ALTEO Group: Hungarian renewable energy and energy services company that develops and operates solar, wind, biomass, and natural gas-fired assets in Hungary. Directly comparable to Greenergy on geography, business model (developer-operator), and multi-technology scope, making it the closest peer.
• Solarpro Holding: Hungarian-headquartered solar EPC and project developer active across CEE. Comparable to Greenergy as a regional renewable developer competing for the same project pipeline in Hungary and surrounding markets.
• Encavis AG: European renewable energy operator that owns and operates solar and wind parks across multiple EU countries. Comparable as a mid-sized IPP that acquires and operates renewable assets, similar to Greenergy's developer-operator model.

Regional players

• ERG S.p.A. Italian renewable energy operator focused on wind, solar, and storage across Southern Europe. Comparable as a European mid-sized multi-technology renewable operator, though primarily Italy-focused rather than CEE-focused like Greenergy.
