Renewable Energy Development

The company has developed more than 1.450 MW of wind and solar projects through its subsidiary companies and cooperations with a number of investors. This marks a significant achievement in the renewable energy sector and is a substantial contribution for green energy transition.

In terms of energy output, more than 700MW of wind energy projects, depending on factors such as turbine efficiency and wind conditions, could generate between 2.1 to 2.5 terawatt-hours (TWh) of electricity annually. Similarly, 750 MW solar PV projects, with sufficient sunshine, could produce approximately 1.1 to 1.6 TWh per year. Together, these projects may generate between 3.2 to 4.1 TWh of electricity annually, potentially providing power to hundreds of thousands of homes, depending on regional energy consumption patterns.

From an environmental perspective, this large-scale shift to renewable energy reduces dependency on fossil fuels, significantly lowering greenhouse gas emissions. By displacing carbon-intensive sources, these renewable projects have the potential to offset millions of tons of CO₂ annually, contributing to global efforts to mitigate climate change.

The geographical location of these projects plays a critical role in their success. Wind energy thrives in areas with consistent wind patterns, while solar projects perform best in regions with ample sunlight. The company has strategically placed these projects in diverse locations, in order not only to maximize efficiency but also enhance energy grid resilience by reducing over-reliance on specific regions.

Economically, the development of both wind and solar projects adds a significant achievement to the company’s role in the renewable energy industry. This diverse portfolio helps the company capture a growing market share in the clean energy sector, which is poised for further expansion as country’s energy transitions accelerate.

In conclusion, the development of more than 1.4 GW of wind and solar energy projects underscores the company's role in driving the transition to renewable energy. The experience gained from these projects encourages the company to expand further in the clean energy sector. The environmental, economic, and strategic advantages of these projects place the company in a strong position to capitalize on future growth opportunities in the clean energy sector.

Wind Resource Assessments Experience

Wind resource assessments (WRAs) are critical for the development of wind farms. They determine the potential for wind energy generation at specific locations by measuring wind characteristics, and other atmospheric conditions over a period of time.

1. Scale of Assessments

GaiaComm since 2006, has conducted hundreds of wind resource assessments in Greece demonstrating substantial experience and expertise. WRAs typically involve the installation of meteorological masts, LiDAR systems, and data analysis over several years. A large number of these assessments signifies the company’s wide reach and influence across various regions in Greece.

The variety of terrains and microclimates in Greece, from coastal areas to mountainous regions, presents diverse challenges. Successful completion of hundreds of assessments suggests the strong capabilities in handling complex environmental conditions over challenging terrain conditions.

2. Contribution to Energy Capacity (>3.500 MW)

GaiaComm has offered its services for the development of more than 3.500 MW of wind energy projects in Greece. For context, 1 MW can power approximately 650-1.000 households per year. So, 3.500 MW could supply energy to roughly 2.3 million households annually.

This level of involvement represents a significant portion of Greece's renewable energy capacity, contributing to national goals for clean energy and reducing dependency on fossil fuels. Greece has been striving to increase its share of renewable energy as part of the European Union’s broader Green Deal and climate goals.
