A hypothetical case of what production patterns from wind might look like through a year with increased installed capacity of wind farms.
Long-Term Market trends and forecasts
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 significant despite the growing diversification of wind farm sites.
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 towards regional and NEM-wide demand
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.
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 factor at play in why peak demand has been changing.
A longer-term look at how summer (peak and average) demand has trended over the 15 years of NEM history to date.
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.
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 pricing – generated significant interest in the press, and interested us to open NEM-Review and have a look at longer term trends, and the extent to which that attribution might be true.
A look at the trend towards deeper liquidity of trading of electricity derivatives in Australia’s National Electricity Market (NEM).
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 the introduction of the carbon tax.
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 on production volumes from the hydro facilities around the NEM.
Including more than a decade of data for Queensland’s peak electricity demand (pre-NEM) reveals a more nuanced picture.
Extending our analysis of the pattern of demand growth (NEM-Wide) to see if the pattern has been the same at a regional level.
A list of 10 factors that are impacting on electricity consumption across the National Electricity Market.
Further analysis of the way that electricity demand patterns (NEM-wide) are changing in Australia’s National Electricity Market
Prompted by Ben Skinner’s question, we’ve had a bit more of a look at demand patterns in the NEM (NEM-wide).
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.
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
Our Managing Director spoke at the “Australian Energy & Utility Summit 08” in
Sydney on Tuesday 22nd July 2008, touching on a number of issues including the nature of peak demand forecasts (for winter in the NSW region) over the coming 10 years
