Steel pipe producer Corinth Pipeworks has officially launched a 7.1 MW photovoltaic installation at its site in the Thisvi Industrial Area, marking what the company describes as the largest industrial rooftop PV system in Greece.
The facility, located northwest of Athens, is projected to meet roughly 25% of the factory’s electricity requirements, generating an estimated 10 GWh of power annually. Corinth Pipeworks (CPW), a subsidiary of Cenergy Holdings, confirmed the commissioning of the system and underlined its status as the biggest industrial rooftop photovoltaic facility in the country.
The rooftop PV system project was carried out through an ESCO scheme, with Survey Digital Photovoltaics responsible for both design and implementation. Financing was provided jointly by investment firm Sirec Energy and Survey Digital Photovoltaics, with support from Piraeus Bank. According to the terms of a 10-year lease, the solar system will be transferred to Corinth Pipeworks at no cost. The installation is designed exclusively for on-site consumption, with no electricity fed into the high-voltage grid.
Covering almost six hectares across two factory rooftops at a height of ten meters, the project includes 12,000 solar panels. Combined with a power purchase agreement (PPA) linked to a wind farm, the solar facility enabled Corinth Pipeworks to exceed its 2025 objective of sourcing 80% of its total energy needs from renewable sources. The company’s manufacturing portfolio also extends to pipes intended for hydrogen pipeline infrastructure.
“This choice carries particular significance, as it comes from an organization with both the technical capacity to develop the photovoltaic system and manage the generated energy, as well as the financial capacity to finance the investment independently. Yet, it chose to move forward in collaboration with us and Survey Digital Photovoltaics, recognizing the value of strategic partnership,” said Vice President of Sirec Energy Vangelis Bardis.
