Such an increase would exceed the current market price of aluminium, potentially placing European aluminium producers at a competitive disadvantage. We assume an electricity intensity of 15 MWh pertonne of aluminium, source CEPS (2013), and a marginal C02 content in electricity of 700 g/kWh. The market deficit (consumption minus production) in Europe is currently almost 3 million tonnes, meaning that consumption exceeds production by 3 million tonnes (see Figure 13).
