Energy policy objective function
Energy Policy Objective termFunction

  • Energy is considered an essential service for residential consumers

  • Importantly, gas is also a vital input in the production of many domestically produced goods and services

  • In this context, energy policy has three primary objectives :

    • Security of supply;

    • Minimised cost; and

    • Removal negative production externalities (i.e. greenhouse emissions)

  • Inherent conflicts exist between these objectives:

    • Removing negative externalities increases end user pricing

    • Greater security of supply may increase end user pricing

Business use
Business use term

Many industries are critically reliant upon natural gas for production of their goods and services

APPEA Conference

Household use
Household use term

3.6 million small connections to the east-coast gas network that use gas for “essential service” applications

  • Hot water

  • Cooking

  • Space heating

Supply of natural gas
Supply of natural gas term

East-coast natural gas supplies are now dominated by coal-seam gas

Demand for natural gas1
Demand for natural gas term

All mainland east-coast states use significant quantities of gas for a diverse range of uses

Demand for natural gas2
Demand for natural gas term

Growth in demand for natural gas has been steady since 1980 after rapid growth in the 1970s

Demand for natural gas3
Demand for natural gas term

But demand for gas is set to go through a “step change” due to the development of LNG projects in QLD

Demand supply position by 2030
Demand/supply position by 2030 term

There is a tight supply/demand balance by 2030 even prior to the consideration of new gas-fired generation

Gas fired generation
Gas-fired generation term

The Clean Energy Future Act is likely to alter the economics of base and intermediate power generation

APPEA Conference

Gas fired generation1
Gas-fired generation term

But changes to gas pricing alter the economics related to fuel switching for the purpose of emission reduction

APPEA Conference

Gas fired generation2
Gas-fired generation term

And peak demand continues to grow requiring further investment in gas-fired open cycle turbines

APPEA Conference

Gas fired generation3
Gas-fired generation term

Both climate change policy and peak demand generation is likely to result in an increase in gas-fired generation

APPEA Conference

Demand supply position by 20301
Demand/supply position by 2030 generation)

There could be a shortage of gas across the east-coast by 2030 if significant new power generation loads materialise

Policy implications
Policy implications generation)


Policy implications1
Policy implications generation)

There must be greater integration of energy policy and planning policy reflecting the importance of security of supply

  • This paper has demonstrated the extremely tight demand/supply balance for east-coast gas to 2030

  • Gas plays a critical role in the economy

    • Essential input for business

    • Essential service for households

  • Rapid development of coal-seam gas reserves has increased community focus on production of natural gas

  • But there has been little community focus on security of gas supplies

  • Policy makers and the industry need to work together to communicate the importance of securing gas supplies

  • Integration of planning policy and energy policy is critical

A lesson learned from electricity

Sensible public policy may become more difficult if issues are not addressed ahead of time
