About Survey Digital
We operate in Development Construction Maintenance of photovoltaics
Survey Digital Photovoltaics, a company owned 100% by Dr. Kostis Daniilidis, deals exclusively with photovoltaic parks under the logic of “one stop shop”. The company internally provides all the services required for the implementation of utility-scale photovoltaic parks, accounting support services, real estate, licensing, bank financing, design, supply, construction, commissioning, operation, maintenance, as well as cumulative representation on the Stock Exchange Energy.
In the field of project development, the company is developing a project portfolio of approximately 600MW, most of which have received environmental requirements. The company has issued letters of guarantee in favor of RAE/ADMIE from Alpha Bank and Optima Bank, totaling €24.6 million.
In the field of project construction, the company closed 2022 with completed 30 projects with a total capacity of 14.5MW, but also with newly signed engineering, procurement and construction contracts for 76 projects with a total capacity of 62MW for 2023 (with outstanding €42m. euro). It is noted that complete EPC contracts were signed for all 84 projects, i.e. contracts that include the entire supply of equipment for the projects. The construction of all new projects will be completed within the first 6 months of 2023.
In the operation & maintenance sector, the company signed new contracts for 68 PV plants with a total capacity of 84.28 MW within 2022, rising the company’s total operation and maintenance portfolio to 140 MW.
In the field of Cumulative Representation, the company has received a 500MW FOSE license and started trading on the Energy Exchange in October 2022, currently having in its portfolio as a FOSE 16 projects with a total capacity of 8MW, as well as signed contracts for 230MW in the future.
The company’s scaling is achieved by making the most of a highly reliable and tested quality management system (according to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018), on the basis of which new staff is trained and take up their duties in minimum time, ensuring that the company’s service quality indicators remain at their maximum. Therefore, the company by the end of 2022 has a permanent staff of 50+ people and also a very strong network of subcontractors nationwide of 100+ people.
Finally, Survey Digital Photovoltaics has been certified as a Great Place to Work company, as well as a company compatible with Action 7 (cheap and clean energy) of the SDGs by the United Nations, while it received the Bravo Award 2022 for the action of “Providing very cheap and clean energy to Greek heavy industry”. The company has already started its certification for ESGs, which it is expected to receive within 2023.
