Renewable Energy Greece

Greece is on the cusp of a renewable energy transformation, setting ambitious targets and investing heavily to secure a sustainable, resilient energy future. Amid escalating climate challenges, the nation’s commitment to green energy is marked by large-scale solar, wind, and energy storage projects aimed at cutting emissions and providing affordable electricity to its citizens. As Greece navigates this complex journey, it confronts both opportunities and challenges in achieving its vision of becoming a European renewable energy leader.

As part of its commitment to the green transition, Greece is focusing on large-scale renewable energy projects to maintain affordable electricity for consumers and meet ambitious climate targets. Speaking at the 6th Renewable & Storage Forum in Athens, Minister of Environment and Energy Thodoros Skylakakis highlighted the government’s dual approach: while small producers and energy communities play an important role, large renewable installations are prioritized due to their cost-efficiency and ability to achieve economies of scale.

These large projects are key to reaching the revised targets in Greece’s National Energy and Climate Plan (NECP), which aims for 82% of electricity generation from renewables by 2030—a significant increase from the previous 66% target. This updated goal aligns with the European Union's objectives, particularly the aim to reduce greenhouse gas emissions by at least 55% by 2030. To reach these ambitious benchmarks, Greece estimates it will need €95 billion ($104 billion) in new investments, particularly to enhance solar, wind, and energy storage infrastructure.

While smaller projects will operate under a net-billing scheme, large installations are expected to lead the energy transition, providing households and industries with more affordable, clean energy. Notably, the government is also exploring adjustments to grid connection priorities to support wind energy, which has not seen the same growth as solar power in recent years.

Building Resilience Amid Climate Challenges

Frequent wildfires and floods have underscored the urgency of climate action, placing added pressure on Greece’s infrastructure and economy. Minister Skylakakis acknowledged that while the NECP positions Greece as a leader in the EU's green energy efforts, it cannot entirely mitigate the immediate impacts of climate change, which are already affecting communities and infrastructure across the country.

Greece’s Wind Farm Expansion: Path to a Renewable Powerhouse or Threat to Local Landscapes?

Currently, the country’s central region holds the majority of its wind capacity, contributing substantially to Greece’s plan to achieve 6,500 MW of wind power within the next three years. Major investors like Terna Energy are focusing heavily on offshore projects, seizing the opportunity offered by Greece’s high coastal winds. As Costas Ilias, Terna’s operations manager, points out, harnessing these winds can significantly reduce CO₂ emissions and ease Greece’s reliance on foreign energy sources.

Yet, despite this momentum, Greece’s renewable energy journey has encountered both delays and controversy. After a major solar energy boom from 2011 to 2013, growth slowed markedly, with only limited solar capacity added between 2014 and 2018. This slowdown caused Greece to miss its 2020 target of 40% renewables in its energy mix. However, recent support from the European Wind Power Action Plan and significant grants from the European Investment Bank have helped Greece fast-track renewable project approvals, spurring optimism that the country can meet its 2030 targets.

Local Resistance and Environmental Concerns

While there is undeniable enthusiasm for the potential of Greece’s wind energy sector, local resistance is growing. Many communities and environmental advocates argue that wind farms disrupt natural landscapes, impact local biodiversity, and pose risks to Greece’s thriving tourism industry. Professor Vassiliki Kati, an expert in biodiversity, underscores that Greece’s reliance on mountainous areas for wind projects—92% of Greek wind farms are situated in these zones, compared to just 12% in Austria—demonstrates a need for more cautious spatial planning. These concerns echo across various regions, where the visual and environmental impact of wind turbines on scenic and ecologically sensitive areas raises legitimate concerns for locals.

The central question remains: how can Greece balance its energy ambitions with the protection of its unique natural and cultural landscapes? As Greece considers these challenges, the integration of wind projects with minimal ecological impact and the involvement of local stakeholders in planning processes will be critical.

Energy Storage and Grid Infrastructure Investments

To complement its wind farm expansion, Greece is also making significant strides in energy storage, which will be crucial for managing the fluctuating supply of wind-generated power. Terna Energy’s hydropower storage project in Amfilochia, for instance, can store up to 5 GWh of wind electricity, providing on-demand energy during periods of low generation. This €650 million project, bolstered by €250 million in EU grants, is one of several aimed at enhancing Greece’s energy resilience. These storage solutions are essential for balancing the grid and ensuring that surplus wind power can be tapped into when needed.

However, the challenge does not stop at energy storage. The European Commission estimates that over €500 billion investment in grid upgrades will be necessary across Europe to handle the expected growth in renewable energy. Greece is preparing for this reality by planning several interconnections to export surplus green energy to Central Europe through the Balkans and Italy. Planned connections with Egypt and Saudi Arabia further reflect Greece’s ambition to position itself as a key green energy exporter in Europe, contributing to energy security amid the shifts caused by the ongoing Russia-Ukraine conflict.

Toward a Sustainable Future?

As Greece navigates the complex path to becoming a renewable energy hub, it faces the dual challenge of realizing its green ambitions while addressing local concerns and environmental impacts. The success of this transition will likely depend on Greece’s ability to balance these competing interests—securing both public and ecological buy-in to ensure that the journey toward a renewable energy future does not come at the cost of its cultural and natural heritage.

The potential is immense: Greece’s wind and solar resources, coupled with strategic storage and grid development, place it in a prime position to support Europe’s energy needs. With careful planning and consideration for local and environmental voices, Greece could indeed become a leader in Europe’s renewable energy landscape—setting a precedent for balancing innovation with preservation.
