Helios One
Larissa, Greece
About this project
Helios One is a 4.8 MWp ground-mounted plant on the Thessaly plain, 18 km west of Larissa. It was connected to the grid in March 2024 and has two full seasons of metered production behind it.
Its output is sold under a ten-year corporate power purchase agreement with an investment-grade Greek electricity supplier at €76/MWh, indexed at 2% a year. The plant carries no project debt, so distributions depend on sunlight and the contract, not on refinancing.
The SPV owns the land lease, the equipment and the grid connection outright. An operations partner handles maintenance, monitoring and insurance.
