4 October 2016, The Conversation, South Australian blackout: renewables aren’t a threat to energy security, they’re the future. In the wake of South Australia’s wild weather and state-wide blackout, both Prime Minister Malcolm Turnbull and Energy Minister Josh Frydenberg have emphasised the importance of energy security. Turnbull stated that the blackout was a wake-up call, suggesting that reliance on renewables places very different strains and pressures on a grid than traditional coal-fired power. The assumption that these politicians and others are working off is that South Australia’s wind industry has reduced the state’s energy security. But do these politicians really know what energy security means in a modern energy landscape? The baseload question.  Baseload power is an economic term that refers to power sources that consistently generate electrical power, therefore meeting minimum demand. The minimum demand for electrical power from an electrical grid is referred to as the baseload requirement. The underlying assumption is that the only way of supplying baseload electricity demand is by means of power stations, such as those fired by coal, that operate at full power all day and night. This is a widely held belief in Australia. A former Australian industry minister, Ian Macfarlane, claimed at a uranium industry conference that the only serious alternative way that baseload power can be produced is by hydro and nuclear. But this is not entirely true. In 2014 South Australia got 39% of its electricity from renewable energy (33% wind plus 6% solar). Consequently, the state’s coal-fired power stations have become redundant. Read More here
