In 2010, IPART released an information paper setting out our views at the time on how different types of affordability concerns for utility services and public transport could be addressed.
IPART conducted a survey of residential water, electricity and gas consumers in the Sydney metropolitan, Blue Mountains and Illawarra areas. We obtained matching consumption data from the utilities for 2,192 households.
IPART uses a real rate of return in setting prices to cover a utility's costs. This requires the conversion of a nominal cost of capital to a real cost of capital by adjusting for expected inflation.
