The government has increased the extent of intervention through the Electricity Industry Reform Act 1998, which forced power companies to divest either their energy or their lines business. The Electricity Amendment Act 2001 led to another round of industry reform concentrating on achieving better governance of the electricity market and tighter control of monopoly functions. The "threat of regulation" was extended to the production of a set of regulations that would be brought into effect if the industry's self-regulation did not meet the Government's criteria.
