Dozens of airports in Southeastern Europe invest in solar power, energy efficiency

Airports in Istanbul and Athens are becoming completely self-reliant with their large solar power projects. Many other airports in Southeastern Europe are investing in photovoltaics as well. Together with energy efficiency, electric mobility and waste and wastewater management projects, they aim to decarbonize their operations and reduce their environmental impact.

Surfaces around infrastructure such as railways and motorways are convenient for solar power as there are few alternatives for their use and the technology can directly provide them with electricity. Airports, too, have embraced the global trend of introducing photovoltaics and electrifying operations, and Southeastern Europe is no exception, with several notable investments.

The largest ones in Istanbul and Athens are about to switch 100% to solar power, which would make them some of the first in the world. In addition, airports in the region are increasing energy efficiency and rolling out electric vehicle fleets. They are introducing resource, waste and wastewater management systems to decarbonize their operations and reduce their environmental impact.

Airport operator in Albania expanding to solar power market

In other recent news, the operator of Kukës International Airport Zayed in Albania’s northeast is in the process of obtaining a license to generate and trade electricity. Namely, the company, Global Technical Mechanics, received a concession five months ago in consortium with local construction firm Bami to build and operate a 12 MW solar power plant.

The location at the village of Shtiqen is in the municipality of Kukës. The airport, built with investments by Emaar Properties from the United Arab Emirates, was inaugurated in 2021. However, it ceased operations in the meantime as Wizz Air withdrew from the facility.

The entire Vlora International Airport, which is under construction, will be covered with solar panels, Albanian officials said earlier. The PV project is for 5.2 MW. A consortium led by Swiss-based Mabco Constructions is building and financing the construction. The firm is part of Mabetex Group, controlled by Behgjet Pacolli, Kosovar businessman and former president, deputy prime minister and foreign minister.

Zagreb Airport starts with small PV unit

Zagreb Airport, which installed a 250 kW photovoltaic unit this year, said it plans to expand it soon. In addition, it switched to 100% renewable energy supply.

Like other airports in the region, the main one in Croatia replaced conventional, halogen lighting with LED. The operator has committed to cutting its emissions in accordance with the recommendations from the Intergovernmental Panel on Climate Change (IPCC).

Zagreb Airport is renovating its buildings and increasingly using solar energy for heating water. Interestingly, it plans to switch from diesel-fueled generators to hydrogen-ready systems.

Athens to integrate strong battery with its arrays

Athens International Airport Eleftherios Venizelos commissioned an 8.05 MW solar park in 2011, followed by another one in 2023, with 15.8 MW in peak capacity.

This year two more units with a combined peak capacity of 35.5 MW are coming online, together with a battery energy storage system (BESS) of 82 MWh.

The operator of Turkey’s largest airport is completing a photovoltaic park of nearly 200 MW and aiming to cover almost all its energy needs from renewable sources by the end of the decade

IGA Istanbul Airport reported that its greenhouse gas emissions in 2024 were 10.5% lower than its goal. Moreover, its operator increased its 2030 renewable energy target from 50% to 90%.

Namely, it expects its Eskişehir solar farm of a whopping 199.3 MW to begin operations before the end of the year. The location spans 300 hectares and the investment amounts to EUR 212 million. The PV park will generate an estimated 340 GWh per year.

Dalaman Airport hosts world’s largest rooftop solar power plant among airport terminals

Several other airports in Turkey are also decarbonizing their electricity systems. TAV Airports Holding (TAV Havalimanları Holding), part of Groupe ADP, completed a solar power plant 6.7 MW in peak capacity at its Milas-Bodrum Airport in the country’s southwest. Within the same project for setting up PV systems at parking areas, the Izmir Adnan Menderes Airport is getting a 5.9 MW unit.

Dalaman Airport, near Bodrum, operates a solar power plant of 8.3 MW in peak capacity. It is the world’s largest on the roof of an airport terminal building.

The facility now covers more than 55% of its consumption from solar energy. The investment was worth EUR 5.4 million. The operator, YDA Airport Investment and Management, has vowed to reach 100% in phase two. The airport has completely switched to electric vehicles.

In 2023, airports Milas-Bodrum, Gaziantep, Erzurum and Ordu-Giresun all commissioned smaller PV systems.

Romanian operators leaning on EU funds

Iași International Airport is about to expand its 1 MW solar power plant, installed in 2023. It was the first in Romania in the sector. The management intends to add 5 MW and a 2 MW energy storage unit.

The investment will reportedly be supported with a grant from the European Union’s Modernisation Fund. The hybrid power plant is supposed to cover a fifth of the electricity consumption of the facility in Romania’s far northeast.

Maramureş International Airport (AIM) is also seeking funding, for a system of 2.6 MW in peak capacity on parking canopies. It would include battery storage.

The PV unit would feature 25 inverters of 100 kW each. The project, worth EUR 12.1 million, should be complete by the end of next year, the management said. The facility is in Romania’s northwest, near the border with Ukraine and Hungary.

Cluj International Airport Avram Iancu said in December that it would install a PV system with batteries. It claimed it would make it energy independent in 2026.

Bacau International Airport George Enescu is another one that applied for funds. The management envisages a 1.25 MW solar power unit and a BESS of 2.1 MWh in capacity, to fully cover electricity consumption.

Sibiu International Airport is developing a project for a ground-mounted unit of 1.7 MW in peak capacity. The site is two kilometers from the terminal.

The management is expecting to cover the costs mainly with a grant via the Modernisation Fund. It said the PV park would be completed within a year and a half and suggested that it would introduce electric cars and buses and charging stations.

Notably, National Company Bucharest Airports (CNAB) has a geotermal energy project.

Hermes Airports equipped its two facilities with PV systems in 2023

Hermes Airports commissioned two solar power plants in Cyprus two years ago. The unit at Larnaka International Airport has 3.5 MW in peak capacity and the one at Pafos International Airport has 1.1 MW. They cover 25% and 30%, respectively, of the facilities’ electricity needs.

Belgrade International Airport in Serbia commissioned a PV system of 1 MW in peak capacity in 2022. The facility’s concessionaire, Vinci Airports, has also set up solar-powered LED lighting.

International airports in Sarajevo and Tuzla in Bosnia and Herzegovina unveiled plans for PV systems a few years ago.
