The development on Evia island demonstrates the sector’s potential. Despite initially facing local resistance, the project now hosts over 700 MW of wind capacity, generating substantial municipal revenues while providing clean electricity for hundreds of thousands of homes.

The Emerging Offshore Wind Sector

Greece’s offshore wind sector represents the next frontier in renewable development. The government has recently unveiled a framework targeting 2 GW of offshore wind by 2030, with the first auction expected in 2025.

“The deep waters surrounding much of Greece make floating offshore wind technology particularly relevant here,” notes Panagiotis Ladakakos, president of the Hellenic Wind Energy Association. “Early investors who build relationships now may secure significant advantages as this sector develops.”

Initial development zones have been identified in the Aegean Sea and the Gulf of Thrace, with extensive marine spatial planning currently underway to balance energy production with marine conservation and tourism considerations.

Investment Models and Structures

Several investment approaches have proven successful in the Greek renewable market:

Joint ventures between international investors and local developers have proven particularly successful. Take the example of Total Eren’s partnership with local developer EREN Hellas, which has facilitated the development of over 300 MW of renewable capacity across multiple projects, leveraging international financing capabilities with local market knowledge.

Property Considerations for Renewable Projects

Securing appropriate land for renewable projects remains one of the fundamental challenges in the Greek market. While investors once focused exclusively on technical potential, successful developers now consider a broader range of factors:

• Special land designations: Including forestry zones, archaeological areas, and Natura 2000 protected sites
• Grid connection proximity: As available capacity becomes scarcer, land near substations commands premium prices
• Local community sentiment: Areas with previous positive experiences with renewables typically offer smoother development paths

For those looking to combine renewable investments with property acquisition, Greece offers interesting opportunities. Many developers have successfully acquired flats for sale in greece near their project locations, serving both as operational bases and potential rental income sources during the development phase.

Innovative approaches are emerging, such as agrivoltaics—the combination of agricultural production with solar installations. A pioneering project in Thessaly allows continued farming beneath elevated solar panels, increasing land productivity while providing additional income for local farmers.

Navigating the Regulatory Framework

Greece’s regulatory framework for renewables has undergone significant positive reforms since 2020, though navigating the system still requires expertise.

The licensing process now follows a more streamlined approach:

1. Producer Certificate: Obtained through the electronic platform of the Regulatory Authority
2. Environmental Approval: Varying requirements based on project size and location
3. Grid Connection Terms: Negotiated with the system operator (ADMIE or DEDDIE)
4. Installation License: Consolidated permit replacing several previous authorizations
5. Power Purchase Agreement: Either through auctions or bilateral contracts

Recent reforms have introduced parallel processing for many of these steps, potentially reducing total permitting time from 5+ years to as little as 14-24 months for well-prepared applications.

Critical regulatory considerations include:

• The special zoning framework for renewables, which designates appropriate and restricted areas
• Local content requirements in certain auction categories
• Grid connection cost allocation rules
• Environmental compensation measures, particularly in forested areas
