Federal Court finding relating to Pelican Point CCGT on 8th February 2017 … and upcoming market changes
Also in the news this week (a Federal Court judgement in relation to AER instituted proceedings against Engie in relation to Pelican Point from 8th Feb 2017) … which is coincidental with upcoming changes in the market for generator obligations.
EnerNOC seems to have grossly under-represented the amount of Demand Response active in the NEM
The level of Demand Response currently active in Australia’s National Electricity Market is higher than some are estimating.
Small solar owners saved the NSW electricity market $888 million during heatwave
New South Wales recently experienced a severe heatwave, which saw parts of the state exceed 45°C. During this three day period, small solar PV (i.e. PV systems that are not registered as generators in the NEM), generated about 17 GWh of power.
How tight demand/supply situations can make solar forecasting important
NSW demand rose to a near-record high on Friday the 10th of February, and QLD soared to a new record demand on that Sunday, amidst an intense heatwave. While this heat-stressed our electricity markets and infrastructure, the nation’s rooftop solar PV systems were providing critical load reduction under plentiful sunshine.
Five fixes for the NEM
Load shedding in South Australia on Wednesday 8 February and successive ‘close shaves’ in NSW and Queensland as the heatwave spread north have exposed serious weaknesses in the national electricity market (NEM).

Examining why Pelican Point didn’t bid full capacity into the NEM on Wednesday 8 February
Some thoughts by our guest author, about possible reasons why Engie did not bid full output of Pelican Point power station into AEMO on Wednesday 8th February (i.e. the time at which load shedding eventuated).
