Long-Term Market trends and forecasts

As we have the time, we’ll provide some commentary here about the methods used by the various bodies for “long term” (which in the NEM means 10-years, typically)  forecasting.

Where they don’t fit elsewhere, we’ll also put articles here looking at longer-term trends in the historical data.

It’s very misleading to claim “Since the introduction of the National Electricity Market in 1996 the wholesale price of energy has risen dramatically”

The wholesale cost of electricity has risen (too fast, too high) in recent years. However let's not let ourselves be conned into believing that this has arisen, now, because of the creation of the NEM back in 1998.

Where is the east coast domgas development boom?

When markets operate normally, a sharp rise in the price of any commodity triggers a boom in exploration, development and new supply. But this is not seeming to happen in response to high domestic gas prices. In this article, guest author (Graeme Bethune) examines why.

Three Possible Business Models for Distributed Storage

GSES recently gave a presentation at the APVI workshop in Brisbane as part of the International Battery Association conference.

The content of the presentation would be of interest to WattClarity readers, hence this guest post - which focuses on three possible future business models, that would mean very different outcomes to the incumbents that have become accustomed to "business as usual" over many years.

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 significant despite the growing diversification of wind farm sites.
