The consultants blame the Belgian Government's decision to shy away from nuclear energy and coal and opt for renewable and gas-fuelled electricity generation.
Belgian business can look forward to a doubling of its electricity bill.
The Boston Consulting Group examined the matter at the request of the Belgian Employers' Organisation, the VBO.
The choices in favour of renewables and gas mean that billions of euros will have to be found in coming years to fund the investments in new installations. These investments will lead to higher energy prices.
The Boston Consulting Group's Jonas Geerinck notes that other countries that have adopted similar policies are communicating about it in a much better way: "It's important to maintain countries’ competitive edge. In Germany a choice has been made in favour of getting households to pay more in order to keep costs for industry lower. In Germany even the unions support this principle."
The Boston Consulting Group's report forecasts that Belgian CO2 emissions will grow once again starting 2020 as nuclear drops out of the equation.
Jonas Geerinck: "To implement the choices made we urgently need investments. In order to attract investors we need to restore confidence in the sector. Otherwise the government will have to bear all the costs."
The daily De Tijd reports that the Belgian Government will soon take a decision on the Energy Secretary's Energy Plan that envisages the closure of the Doel 1 and 2 nuclear reactors by 2015.
