Australia\u2019s east coast solar generation is replacing coal by only 2% in late summer<\/a><\/h3>\n
\n

This is an analysis of late summer. Data are taken from Open NEM: http:\/\/opennem.org.au\/#<\/a>
\nThe graphs in this post are a bit different from those on the above website<\/p>\n

\"Open_NEM_All_States_21-28Feb2018\"
\nFig 1: Generation by fuel: 55% black coal, 19% brown coal, 9% gas, 7% wind, 6% hydro, 4% solar<\/p>\n

All times shown in NEM time. AEST is one hour later.
\nThe vertical lines show 12:00 noon, the start of hot afternoons. Note that Feb 24th \u2013 25th was a weekend with lower demand.<\/p>\n

Coal<\/h4>\n

Victoria\u2019s inflexible brown coal was running 24\/7 at an average of around 4,500 MW, near to capacity of 4,630 MW. The minimum was 3,800 MW on 21\/2\/2018. There are problems with Loy Yang as reported by The Australia Institute: http:\/\/www.tai.org.au\/gas-coal-watch<\/a>

\"Open_NEM_All_States_Coal_21-28Feb2018\"Fig 3: Black coal generation<\/p>\n

Black coal had an average generation of 13,000 MW, variable between a minimum of 9,400 MW (at night around 3 am, -27% down from average) and 15,300 MW (afternoon, +18% above average)<\/p>\n

\"QLD_coal_fired_power_plants_Dec2017\"<\/p>\n

Fig 5: Nameplate capacities of Queensland black coal<\/p>\n

During day time, black coal is less variable as shown in this graph:<\/p>\n

\"Black_coal_22-27Feb2018\"Fig 6: Black coal generation over 24 hrs\/6 days<\/p>\n

Compared to 7 am power generation at 7 pm was up to 800 MW (average 500 MW) higher or around 4%-6% which is not very peaky.<\/p>\n
