Digging further into ‘Aggregate Scheduled Target’, to understand what Dispatchable Capacity is actually required
In conjunction with the analysis done to complete GenInsights Quarterly Update for Q1 2023 (released today), here’s 14 years of daily data of ‘Aggregate Scheduled Target’ that might help to illustrate the aggregate requirement for fully dispatchable capacity of some type as the closure of coal accelerates into the future.
