In principle, nuclear energy is also well-positioned to contribute to adequate capacity margins and stable loads. By providing stable baseload electricity it reduces the complications of integrating intermittent or distributed generation, since as a reliable baseload source of power it helps maintain frequency and voltage. Expressed differently, the massive use of intermittent sources will require a significant fraction of continuously operating and robust baseload electric power generation fuelled by more steady sources. While the technical parameters of nuclear energy set limits to the extent it can make up for sudden load changes itself, the development of smart grids and demand response should smooth load variations (and thus increase the share of baseload demand). This would considerably strengthen the case for nuclear energy in co-operation with both other supply-side and demand-side technologies. Price volatility in liberalised electricity markets (and reinforced by intermittent renewables) does remain a challenge and needs to be addressed by appropriate means such as long-term contracts.
