17-year trend of aggregated coal unit unavailability as from the Generator Report Card
Some excerpts from the Generator Report Card to sample some of the analysis we performed to assess various aspects of the ‘dependability’ of coal-fired power stations in the NEM. In this post we highlight availability (or, more precisely, the level of unavailability) as an aggregated monthly volumetric measure trended over 17 years.
Five different aspects of assessing the “dependability” of coal-fired power (in the Generator Report Card)
The framework we used to analyse the extent to which coal-fired power is “dependable” in the Generator Report Card, and the extent to which it’s been changing.
