‘Maximising Value in the NEM’, with a particular focus on Large Solar Farms

On Thursday 21st May, Marcelle Gannon and Jonathon Dyson jointly shared a large number of insights and tips to help those interested in developing and/or operating Large Solar Farms in the NEM maximise the value they receive. Useful also for those interested in Wind Farms (i.e. any Semi-Scheduled plant), and also hybrid operations using Batteries.





Kogan Creek trip on 9th October 2019 delivers highest ‘aggregate Raw Off-Target’ for the 2019 year for ‘all Coal’

Following on from Tuesday’s main article (summarising results across 105,120 dispatch intervals through 2019 for ‘all Coal’ and ‘all Wind’ groupings), this is the first of 4 x Case Studies that look at each of the extremes in outcome.
