A political dispute has emerged in Greece regarding the management and investment levels of the Hellenic Electricity Distribution Network Operator (HEDNO). Former Prime Minister Alexis Tsipras questioned the direction of the operator’s increased revenues and the sufficiency of its investments.

In response, Minister of State Akis Skertsos dismissed these claims as “lies or inaccuracies,” asserting that energy infrastructure investments in Greece have increased to 5.9% of GDP. Skertsos stated that annual investments have quadrupled since 2019, exceeding €1.5 billion.

Supporting data from HEDNO officials indicates that since 2020, approximately 2.8 billion euros have been invested to modernize the electrical grid. The company reported that annual investments rose by 430% compared to 2019 levels, reaching roughly 800 million euros, in an effort to address an investment gap from the 2015–2019 period. A key component of this modernization is the undergrounding of power lines, which has reportedly increased from 200–250 km per year in 2019 to between 1,700 and 1,800 km annually.
