Some business stories begin in the capital, while others take root in the margins—only to eventually become true industry benchmarks. Alesco undoubtedly belongs to the latter. In 2010, at a time when Greece was grappling with the most severe economic crisis in its postwar history, a small technology studio called “Solar Energy Project” opened in Ioannina. Sixteen years later, the company, now rebranded as Alesco S.A., has installed over 55 megawatts of PV capacity nationwide, employs more than 50 specialized technicians, and has signed a memorandum of understanding with Huawei Digital Power to deploy 100 ultra-fast EV charging stations across Greece and Southeast Europe. It is currently expanding its focus to the markets of Albania, Kosovo, and North Macedonia.

Financial performance from fiscal year 2020 to 2024 tells a story of accelerating growth: the company’s EBITDA margin surged from 15.1% in 2020 to 32.1% in 2024, doubling its profitability—a level that is rarely achieved within the industry. In terms of operational footprint: More than 2,000 integrated energy projects have been completed, with over 55 MW of installed PV capacity, more than 100 MW under construction, and a pipeline of over 200 MW of battery energy storage systems (BESS).

Customers such as Niziacos Industrial Company (1 MW on industrial rooftops), Vikos Group (2 MW under net-metering arrangements), and the German LIDL Hellas supermarket chain (23 projects totaling 3.8 MW nationwide) define Alesco’s business profile: the company is capable of serving both residential projects and multinational retail giants.

Alesco’s founder and CEO, Stavros Alexis, noted that in early 2025, Alesco reached a milestone in the electric vehicle sector by installing Greece’s first 600-kilowatt liquid-cooled EV charging station in Paramythia, Thesprotia. This is also the highest-power charging unit ever deployed in the country. This solution is based on Huawei’s FusionCharge liquid-cooled power unit and can be upgraded to 720 kW. Several months later, in November 2025, the partnership with Huawei was elevated to a strategic level: the two parties signed a cooperation memorandum for the period 2025–2027, aiming to build 100 ultra-fast charging stations in Greece and Southeast Europe, the vast majority of which will serve the Greek market.

Alesco CEO Stavros Alex commented: “This agreement provides us with greater momentum, enabling us to consistently and passionately develop solutions that genuinely help our country achieve its energy and climate objectives.” This is not the first time it has received international recognition. In 2024, at the second Global Installers Summit held in China, Huawei awarded Alesco the title of “Global Preferred Installer,” a prestigious honor that very few Greek companies have ever received.

Alesco’s Chief Technology Officer, Konstantinos Goulas, pointed out that what sets Alesco apart is not just its size, but rather the breadth of its market presence. As a comprehensive energy service provider, the company operates across five core business segments. Photovoltaic systems remain its historic core, serving applications ranging from residential rooftops to large-scale industrial facilities under either feed-in tariff or net metering schemes. Battery energy storage systems (BESS) augment power generation capacity and address critical load management challenges for commercial and industrial customers. Electric vehicle charging represents a cutting-edge area, with ultra-fast charging stations already constructed and in operation at strategic locations along the national road network. Building energy upgrades help property owners rapidly reduce energy costs by implementing HVAC, external thermal insulation, underfloor heating, and heat pump systems. Meanwhile, the HVAC business complements the product portfolio by offering integrated HVAC solutions that incorporate equipment from world-leading manufacturers such as Hitachi.

In collaboration with partners such as Alumil, ABB, Huawei, LONGi, and Hitachi, we ensure that every installation bears the hallmark of global technology leaders. Alesco’s 2026 expansion strategy is clearly outlined: a new branch will open in Kozani in the first quarter of 2026; additional branches are planned for Attica and Thessaloniki in the third quarter; and in the fourth quarter, the company’s headquarters will relocate to a newly constructed 1,000-square-meter facility in Ioannina, which will also house a distribution center.

From a medium- to long-term perspective, Alesco is looking beyond national borders: its strategy is expanding into the Balkans, with Albania, Kosovo, and North Macedonia as target markets. These countries are lagging in their energy transitions, presenting significant opportunities for companies with established technological expertise. Certifications under ISO 9001, ISO 14001, ISO 45001, and ISO 50001, together with Huawei’s Preferred Installer designation, serve as its “passport” for international expansion.

In a country where commercial wealth tends to be concentrated solely in urban centers, Alesco presents a rare example: it demonstrates that peripheral regions can also give rise to global players. Starting out as a city accustomed to long winter nights and a lack of investment, it has now become a benchmark model for the Greek business community—one to emulate rather than merely observe from afar.
