Back to the overview

Flemish renovation rate remains low

Network operator Fluvius is adjusting its €4 billion investment plan following a review of current energy trends. Since 2022, the company has been working to strengthen the electricity grid to prepare it for electric cars, heat pumps, solar panels and growing demand from industry. Of the planned 30,000 kilometres of low-voltage cable, 6,500 kilometres have already been tackled. However, the focus is changing: less investment in low voltage for private individuals, more in medium voltage for businesses.

Slower breakthrough among private individuals

Fluvius expects the number of electric cars in Flanders to be lower than previously estimated by 2035: 2.45 million instead of 2.75 million. Company cars in particular are being electrified quickly, but private individuals are switching more slowly. Heat pumps will also take longer than expected to catch on in private homes. By 2035, Fluvius expects there to be 611,000 units, most of which will be in new-build homes. There has been a notable increase in hybrid heat pumps, which run on both gas and electricity, which is driving up demand for power.

 

Renovation rate stagnates, companies lead the way

According to Fluvius, the Flemish renovation rate remains stuck at 1% per year. This is not in line with the ambitions of the Flemish government, but is partly caused by policy choices: buyers are given more time to make their homes more energy efficient and only need to achieve an EPC label D. Companies, on the other hand, are fully committed to electrification, for example by replacing fossil fuel boilers with electric ones. To meet this growing demand, 200 million euros is being shifted from low-voltage to medium-voltage projects, while the total investment budget of 4 billion remains unchanged.
