Network losses, which have been steadily increasing in recent years, continue to drive up retail electricity costs in 2024. Both technical and non-technical losses represented 14.9% of total electricity load in 2021, with unofficial data indicating an increase to 17.7% in the first half of 2022. Current trends suggest that this upward trajectory shows no signs of slowing down.
This issue is particularly burdensome for electricity consumers in Greece. Although supply companies initially absorb the cost of energy losses, these expenses are ultimately passed on to consumers, resulting in an approximate 18% increase in electricity bills. Greece remains one of the few EU countries where network operators are not held accountable for the losses, causing the full financial burden to fall on consumers. This exacerbates energy poverty, disproportionately affecting vulnerable households.
The Greek electricity distribution system operator, DEDDIE, has pointed to the challenge of reducing technical losses, especially with the rise of decentralized energy generation. As renewable energy sources become more widespread, the longer distances between production sites and consumption points contribute to inefficiencies in the grid.
Non-technical losses, such as electricity theft, have also become a growing concern. This issue affects not only marginalized groups but also numerous businesses. In response, DEDDIE is intensifying inspections and enforcing stricter regulations. Furthermore, the deployment of smart meters is seen as a key measure to improve network efficiency and reduce losses in the future.
