IPTO: RES connected to the grid act as a buffer against rising power prices

The Independent Power Transmission Operator (IPTO) has been systematically connecting renewable vigor sources (RES) to the powerfulness system, helping to trim wholesale energy costs.

Through the accelerated integration of caller cleanable vigor capableness and the improvement of modern vigor infrastructure nationwide, the Operator is playing a pivotal role, arsenic it noted, successful shaping a powerfulness procreation premix that is some greener and much resilient to terms volatility. In 2025, the accrued stock of RES—reaching a caller yearly accumulation grounds of astir 26.2 TWh—had a important interaction connected lowering mean prices, adjacent during months of peculiarly precocious request such arsenic August and December. This trend has continued into 2026, with Greece signaling notably little wholesale energy prices compared with different European countries successful the archetypal ten days of March.

The country’s resilience to precocious wholesale energy costs, comparative to different Southeast European states, is erstwhile again confirmed by the containment of Day-Ahead Market prices, contempt planetary developments and the crisp emergence successful substance prices.

Since 2019, the enlargement of grid capableness done the Operator’s projects crossed mainland and land Greece has enabled a aggregate summation successful installed RES capacity. Due to their near-zero marginal outgo of generation, renewables are progressively displacing fossil substance units successful the vigor mix, often driving prices to very debased levels during highest accumulation hours.

At the aforesaid time, the increasing penetration of RES successful the powerfulness system is reducing the country’s reliance connected imported fossil fuels—whose prices and availability fluctuate importantly depending connected planetary developments—thereby strengthening vigor independency and economical sustainability.

IPTO’s concern program besides provides for the upgrade of Greece’s interconnectivity with neighbouring countries and the wider region.

Cross-border interconnections heighten marketplace ratio by allowing energy to travel from regions with surplus supply and little prices to those with deficits and higher prices.

To maximise the benefits of RES and planetary interconnections, storage technologies are of captious importance.

Accelerating the deployment of storage will safeguard Greece’s export imaginable and alteration greater utilisation of renewable energy, while curbing utmost terms fluctuations and reducing the wide outgo of energy supply for consumers.
