Energy News and Market Insights

Financial leverage for RES projects—and especially for energy storage (batteries)—remains at an early stage in Greece. Market fragmentation and the absence of historical data for storage create caution among financiers. However, the regulatory framework is improving, and the first aggregators can serve as examples. There is a clear opportunity for scaling through structured project finance.

The Greek market for photovoltaic (PV) parks under 500 kW shows strong signs of oversaturation. The excessive concentration of such projects in certain areas has caused connection issues and limited the grid’s ability to absorb energy. Opportunities are now found in the acquisition of existing parks, consolidation (aggregation), and the addition of storage. The strategic shift toward larger projects or projects with batteries has become the only viable path.

In Greece, there is a significant lack of aggregation and optimized dispatch mechanisms for small PV and RES projects. Most producers operate independently, without unified management or commercial representation at the portfolio level. This leads to lower returns and the inability to seize opportunities in the day-ahead market or real-time balancing. The absence of coordinated storage further exacerbates inefficiency. There is considerable potential for technological intervention and the creation of aggregator platforms.

Greece has increasing penetration of Renewable Energy Sources (RES), especially photovoltaics (PV). This creates significant instability in the grid, as energy production is intermittent. Batteries are the only technological solution that can stabilize the grid, store cheap energy for resale, and optimize consumption and net-billing.

There is a lack of tailored agreements ensuring certainty regarding cost and delivery time. There is also an insufficient number of providers with specialized knowledge of the Greek market who can propose their own investments or third-party contracts and ensure the project operates optimally and safely throughout its lifetime.
