DEI Group: What the agreement entails
Through this agreement, the DEI Group acquires ABO Energy Polska and ABO Energy Hungary, adding to its portfolio two fully staffed project development platforms along with the specialized local teams operating in each of the two countries. The portfolio includes 29 SPVs holding 99 MW of photovoltaic projects that are either operational or near completion, as well as over 2 GW of projects — spanning solar, wind, and battery storage — at various stages of development.
“This new business move, which follows the DEI Group’s recent entry into the Hungarian market — through the agreement to acquire a 57.5 MW solar park — and the Polish market — through the agreement to acquire a 277.3 MW renewable energy portfolio — significantly accelerates the implementation of the Group’s new strategic development plan for the 2026–2030 period. This plan foresees the Group’s expansion through renewable energy and storage projects in Hungary, Poland, and Slovakia, both through organic growth and acquisitions,” the company states, adding:
“The transaction involves the integration of two fully operational and already staffed local teams with proven expertise in renewable energy project development. The two platforms cover the full management chain, which includes site selection, land securing, permitting, grid connection management through to the Ready-to-Build stage, construction design and supervision, as well as operations, maintenance, and financial monitoring. The integration of these two platforms broadens the Group’s operational capabilities for energy generation and project development in both countries, ensuring long-term organic growth.
The acquired portfolio is characterized by high technological and geographical diversification — encompassing solar, wind, and battery storage — and includes 99 MW of projects that are operational or near completion, along with over 2 GW of projects at various stages of development.”
Statement by Konstantinos Mavros
DEI Group’s Deputy CEO for Renewable Energy, Mr. Konstantinos Mavros, emphasized that “the agreement with ABO Energy represents a decisive qualitative leap for the DEI Group in Central Europe. We are not simply acquiring an outstanding project portfolio — we are integrating two experienced and highly successful local teams in Poland and Hungary into our organization. Combined with our recent agreements with EDP Renewables and Greenvolt, we are building a robust regional platform that will serve as the cornerstone of our international expansion in Central Europe through 2030.”
Accelerating expansion across Central and Southeastern Europe
“To capitalize on the significant opportunities emerging across the broader region, the DEI Group is accelerating its development, targeting a doubling of its total installed capacity to 24.3 GW by 2030, up from 12.4 GW in 2025,” the company concludes. “This will be achieved by significantly increasing new project additions to 2.4 GW per year, primarily in renewable energy, flexible generation, and storage.
The expansion into Hungary and Poland represents the natural geographical continuation of the Group’s already leading position in Greece and Romania, while an extensive investment plan is simultaneously being advanced across other countries of operation, including Italy, Bulgaria, and Croatia. By 2030, 45% of the Group’s installed capacity will be located outside Greece, supported by a balanced energy mix encompassing all modern forms of generation — solar, wind, hydroelectric, and natural gas — as well as storage, ensuring both geographical and technological diversification.
In an era where energy and technology have become critical factors of competitiveness, security, and resilience, the DEI Group is evolving into a pillar of stability for the European market, investing in critical energy and technological infrastructure that reinforces the broader region and creates long-term value.”
