We track retailers’ electricity and gas prices

There are many electricity and gas retailers in the market, that all charge their own prices. As part of our market monitoring role, we track these prices over time.

The worksheet in the table below shows the median electricity bill since 2014 and the median gas bill since 2018, for a constant level of consumption for each network area.

Before 2014, IPART set limits on electricity retail prices for the Government retailers in each network. The worksheet in the table below provides a time series of historical regulated retail electricity prices in NSW. The link contains a price index from 1992-93, and indicative customer bills based on regulated prices from 1999-2000.
