What lies ahead for the NEM in 2020? Some lessons from 2019
Guest author, Ben Willacy, takes a first look at the Generator Statistical Digest 2019 and highlights a few initial observations relating to the performance of wind, solar and storage in this energy transition.
Some observations about Storage
Last minute complications mean that I cannot speak at today’s “Queensland Smart Energy Summit” (with Jonathon Dyson being an even better substitute). Here are some of the observations I would have liked to discuss with the audience there…
