We are on track to meet the STC target so why hasn’t the Clearing House worked?
Some observations about where the market for STCs seems headed, following my presentation at All Energy earlier in October.
Long-Term Market trends and forecasts
The changing role of gas in the NEM
A few thoughts from another guest commentator (Paul Taliangis @ Core Energy) about where gas-fired generation volumes look set to go.
The NEM might support 37% energy supplied from wind – but it would still require at least 21GW of non-wind capacity on standby
A hypothetical case of what production patterns from wind might look like through a year with increased installed capacity of wind farms.
Aggregate wind farm output growing, but intermittency still remains
A more detailed look at how the percentage of energy supplied in the NEM from wind has risen to be 3.5% on an annual basis - though the degree of indeterminacy continues to be...
Performance of wind farms, to date in 2013
Here's a view of how daily wind farm production (by region, and NEM-wide) has trended over the 2013 calendar year to date - the correlation of output on a daily basis, and the contribution...
Long-term trend shows coal being crunched
A chart and a table presented today at FutureGAS highlighting how the dominance of coal in power generation across the NEM is starting to shift.
How has Demand Diversity changed, over 15 summers?
Some analysis of the extent to which Demand Diversity (the degree to which peak demands in each region occur at different times) has changed in 15 years. If there are changes, it could be...
A more detailed look at how demand has trended over 15 summers in the NEM
A longer-term look at how summer (peak and average) demand has trended over the 15 years of NEM history to date.
To what extent is Wind reducing spot prices in South Australia?
Some starting thoughts, about the extent to which increased wind farm output has been responsible in the drop in spot prices in South Australia from the high levels seen in 2008.
Trends in Production and Spot Revenues at 4 coal-fired stations
A number of recently announced closures of (and cut-backs in) a variety of coal-fired power station units across the NEM (including Northern, Yallourn, Munmorah and Tarong) - claimed to be a result of carbon...
Liquidity of futures trading in Australia’s National Electricity Market
A look at the trend towards deeper liquidity of trading of electricity derivatives in Australia's National Electricity Market (NEM).
Trends in power station output by fuel type
Some observations about the longer-term trend of electricity production, across the NEM, aggregated across all states by fuel type. This reveals some of the trends that have been developing in recent years prior to...
Hydro generation increases with La Nina
An article recently in one of the main papers about increased flows down the Snowy River prompted the question, internally, about how much the La Nina pattern of the past 24 months had impacted...
A 30-year historical window presents a different picture of demand
Including more than a decade of data for Queensland's peak electricity demand (pre-NEM) reveals a more nuanced picture.
Has the demand pattern been different on a regional basis?
Extending our analysis of the pattern of demand growth (NEM-Wide) to see if the pattern has been the same at a regional level.
Some possible reasons why demand is declining
A list of 10 factors that are impacting on electricity consumption across the National Electricity Market.
How is demand changing in the NEM?
Further analysis of the way that electricity demand patterns (NEM-wide) are changing in Australia's National Electricity Market
Another look at Declining Energy Consumption in the NEM
Prompted by Ben Skinner's question, we've had a bit more of a look at demand patterns in the NEM (NEM-wide).
A decline in energy volumes generated in the NEM
Some observations about where average demand in the NEM has trended over the 12 years of NEM history, following the work done in compiling the 2011 Issue of the "Power Trading Schematic" Market Map.
Initial Thoughts about the AEMO’s Electricity Statement of Opportunities (ESOO) for 2009
Some initial, scattered, thoughts (late on the day of its launch) about the AEMO's first production of the Electricity Statement of Opportunities for 2009
