Winter 2002 – Generator Market Power
From the start of the NEM through until 2001, the NEM was typified by a pricing dichotomy with sustained rock-bottom pricing in NSW, Snowy and Victoria and high and volatile pricing in the extremities (Queensland and South Australia).
In 2001, the QNI interconnection and many generation projects were developed. This led to the convergence of prices between all regions, and the disappearance of price volatility – circumstances that were a real threat to generator profitability.
In response, generators adopted an approach that came to be known as “the economic withholding of capacity” to engineer volatility into the market throughout winter 2002 – and hence higher prices as a result., and generator behaviour.
