Independent Power Producer FARIA Renewables has placed an 81.66 MW order for high-efficiency solar modules from manufacturer LONGi, locking in the supply needed to build out two utility-scale photovoltaic (PV) plants in Greece’s Thessaly region. The agreement covers 125,280 back-contact modules that will equip the 45.51 MW “Athamas” project in Almyros and the 36.15 MW “Mykonos” project in Farsala — together more than 81 MW of new ground-mounted capacity for the Greek grid.
The modules use next-generation back-contact cell technology engineered to maximise energy yield in Greece’s high-irradiance conditions while lowering the levelised cost of energy. Across both sites, FARIA Renewables serves as developer, EPC contractor and ultimate owner — a fully vertical model the company has built its business around — making the supply deal a key step toward bringing both plants online.
The projects land in one of Europe’s fastest-growing solar markets, though not without headwinds: Greek solar parks have faced rising curtailment and periods of negative wholesale prices as capacity outpaces grid and storage build-out, sharpening the focus on tracking technology, high-efficiency modules and storage to protect project economics. The dynamic is playing out across the country, as developers race to add capacity and the technology behind each new plant becomes a competitive differentiator — a trend visible in RWE and PPC’s two new solar farms in Greece’s Northern Macedonia, which points to the same push for higher-efficiency, better-sited solar in Greece’s fast-evolving market.
Athamas Solar plant in Almyros
The 45.51 MW Athamas plant in Almyros is the larger of the two and the biggest solar development FARIA Renewables has undertaken. Its design uses an optimised mixed-structure layout — roughly 35% fixed-tilt structures and 65% single-axis tracking — to balance cost against output across the site. The plant will connect directly to Greece’s 150kV transmission grid through two medium-voltage lines running approximately five kilometres to a private high-voltage substation.
Construction at Athamas began on 1 November 2025, with grid connection targeted for 31 July 2026. Once operational, the project alone is estimated to produce around 80,000 MWh of clean electricity a year — enough to power roughly 16,000 households while avoiding approximately 50,000 tonnes of CO2 emissions annually.
“The Athamas and Mykonos projects represent a massive milestone for us, with Athamas being our largest solar endeavour to date,” said Thalia Valkouma, Chair of the Board and CEO of FARIA Renewables. “By choosing advanced back contact technology and pairing it with smart mixed-structure layouts, we are maximising performance for the energy market and setting a benchmark for future Power Purchase Agreements in the region.”
Mykonos: phased rollout in Farsala
The 36.15 MW Mykonos plant in Farsala broke ground on 1 February 2026 and is scheduled to connect to the grid by 30 June 2027, following on closely from Athamas. Like its sister project, it is being built on privately owned land as part of FARIA’s strategy of converting ready-to-build assets into operating capacity. The staggered timelines allow the developer to bring the larger Athamas plant online first, in mid-2026, before completing Mykonos the following year.
Archaeology meets the energy transition
The Athamas development has also become an unusual meeting point of Greece’s ancient past and its clean-energy future. During preliminary site works, archaeological investigations uncovered burial monuments dating to the prehistoric and Byzantine periods. In line with established scientific protocols, competent archaeological authorities are overseeing the careful excavation, documentation and conservation of human remains and movable artefacts before construction proceeds across the affected areas — an example of how large renewable projects in heritage-rich regions must balance deployment speed with cultural preservation.
Part of a wider Greek build-out
The two Thessaly plants are a small slice of FARIA Renewables’ ambitions. Launched in 2023 as a joint venture between FARIA Group and Omnes Capital’s Capenergie 5 Fund, the company is developing a portfolio of around 3,500 MW across Greece spanning solar, onshore and offshore wind, hybrid plants, battery storage and green hydrogen. It has secured licences for hundreds of megawatts of additional wind and solar capacity and is among the developers awarded support in Greece’s standalone energy-storage auctions.
