Making Privatised Industries more CompetitiveMaking Privatised Industries more Competitive

• Increasing competition in the privatised industries

– allowing competition where there is no natural monopoly

• limited extent of true natural monopoly

– allowing access to grids by competitors

– forbidding suppliers from being grid owners

– capping market share of established firms

– competitive franchising to make monopolies contestable
