Regulatory approval secured for “Data Center Olive” project in Spata

The project is being implemented by GRECO MI Single-Member S.A. and forms part of the broader investment plan of Apto, a data center development and operations company founded by PIMCO and active internationally. Apto’s partnership with Dromeus Capital, one of the leading investors in the Greek real estate sector, marks their first joint investment in Greece and aims to establish a benchmark project for the country’s digital transformation.

The data center will be developed on two adjacent plots with a total area of 62,498.53 sq.m., separated by a public road. On the northeastern plot (Plot A), the two-story DC1 Data Center will be constructed, while the corresponding DC2 facility will be built on the southwestern plot (Plot B). Both plots will include sprinkler tanks, parking areas, security booths, a 2.4-meter-high steel perimeter fence, and all necessary auxiliary infrastructure. In addition, an 80 MVA High Voltage Substation will be installed on Plot B to meet the facility’s increased energy demands.

The buildings will comprise a three-story office section and a two-story server hall section, with maximum power demand reaching up to 80 MW. Cooling systems will be installed on the rooftops, while 40 backup generators will be deployed at ground level to ensure uninterrupted operations. The mechanical and electrical equipment will include 14 Air Handling Units (AHUs), 40 rooftop chillers, a photovoltaic system to enhance energy efficiency, and fuel tanks equipped with enhanced safety measures.

The internal road network will feature three access points, and the development will provide a total of 104 parking spaces, bicycle parking areas, waste storage facilities, and landscaped green spaces covering approximately 15,000 sq.m.

Sustainability and environmental protection are central to the project’s design. The development will follow LEED certification standards or an equivalent system, incorporating bioclimatic architectural principles and the use of Renewable Energy Sources. A comprehensive environmental monitoring system will be implemented throughout both the construction and operational phases to minimize environmental impact. Noise mitigation measures — particularly around generator areas — will be applied, including perimeter acoustic interventions.

Water and waste management constitute key pillars of the project. Provisions include the collection and reuse of rainwater for irrigation and fire protection, the construction of appropriate drainage and flood protection infrastructure, and the recycling and proper management of waste in accordance with applicable legislation. Strict fire protection, cybersecurity, and physical security protocols will also be implemented, supported by detailed risk assessments and certified operational procedures.
