Callide C case study
■ On 25 May 2021, Unit 4 (405MW) at the Callide C coal-fired power station suffered a
turbine fire:
Average RRP prices in Queensland escalated to $15,000 for nearly 2 hours
Qld RRP (A$/MWh)
If BBP had been operational at the time, it would have made $1.3M in gross
margin on 25 May 2021 solely from arbitrage activities
Over the period to 30 June, as prices remained volatile, the BBP would have netted a
total of $4.9M from arbitrage gross margin alone, equating to in excess of 500% of
forecast daily revenues
■ Extreme contingency events such as Callide C are unpredictable, but likely to
increase in frequency as coal plant ages and retires
■ Importantly similar events are not factored into Genex's revenue forecasts for the
BBP and therefore represent substantial upside to equity
