“Risk with the electricity supply in winter”

The technical prerequisites for the energy transition are currently lacking

The technical reality is still a long way from the political requirements for the energy transition. Andreas Eigenbauer, board member of the energy supervisory authority E-Control, listed the problems at a specialist conference. According to an extrapolation from Austria Tech, 330 charging points would have to be installed every day by 2030 in order to meet the requirements for e-mobility. At the end of 2020 there were 3,500 charging points with 7,500 charging points across Austria.

A massive expansion of the charging points is currently not possible. There is a lack of qualified fitters. Therefore, the expansion goals will probably not be achieved. It is similar with photovoltaic systems. There, too, there is a lack of specialist staff for assembly. In addition, there are currently delivery problems with imports from China.

High costs

In order to achieve 100 percent renewable electricity by 2030, according to statistics, investments of around 18 billion euros are necessary for the expansion of the electricity grid, emphasizes Eigenbauer. Gas-fired power plants must continue to be used in winter because the renewable energy sources then deliver significantly less electricity. Self-builder speaks of a “risk with supply in winter”. Especially since e-cars consume significantly more electricity in winter.

E-Control board member Eigenbauer also points out that the existing power grids can transport a maximum of 30 percent of the energy that will be necessary for e-mobility.
