EG.D unveils ten-year distribution grid development plan

EG.D has published a draft ten-year development plan for its distribution grid for the 2026–2035 period. The document outlines planned investment in power lines, substations and grid modernisation in response to growing demand for the connection of new electricity generation sources, particularly photovoltaic power plants, as well as gradual growth in consumption linked to electric mobility, the electrification of heating and new industrial projects. The plan has been submitted for public consultation, along with the other two plans from distribution companies ČEZ Distribuce and PREdistribuce, before being submitted to the Energy Regulatory Office.

EG.D is the Czech Republic’s second-largest electricity distributor in terms of the area it serves. The company’s distribution grid covers approximately 26,499 km², equivalent to around one-third of the country’s area. The company supplies electricity to more than 1.59 million connection points, the vast majority of which are connected at low voltage.

The total length of power lines in EG.D’s distribution grid is nearly 66 thousand kilometres. Of this, approximately 2,425 km consists of extra-high-voltage lines (110 kV), more than 22 thousand kilometres of high-voltage lines and over 41 thousand kilometres of low-voltage lines. The distribution infrastructure is also complemented by 90 110/22 kV substations and more than 21 thousand 22/0.4 kV distribution transformer stations, which transform electricity for local grids.
