Method & Evidence

AimTo determine the feasibility and cost of powering the Australian National Electricity Market entirely with renewable energy sources, specifically wind and photovoltaics, by analyzing hourly energy balances and identifying necessary supporting infrastructure.
MethodEnergy balance analysis
ProcedureAn hourly energy balance analysis was conducted for the Australian National Electricity Market under a 100% renewable energy scenario, primarily utilizing wind and photovoltaics, with existing hydroelectricity and biomass providing the remainder. The study incorporated technology currently deployed in large quantities and assessed the need for additional energy storage and inter-regional interconnection.

Strengths & Limitations

Strengths

  • +Utilizes hourly energy balance analysis for detailed system assessment.
  • +Focuses on currently deployable technologies, avoiding speculative assumptions.

Limitations

The cost estimates are based on past prices and future technology development is uncertain.

Reliability & validity

The study's reliability is supported by its detailed hourly analysis and focus on existing technologies. Validity is strong within the defined scope of the Australian National Electricity Market, though external validity to other markets would require adaptation.

Think critically

What are the potential social and environmental impacts of developing the large-scale pumped hydro storage facilities required by this model?

05

Design Principles

"Grid stability in renewable energy systems is achieved through a combination of distributed generation, energy storage, and intelligent transmission."

This research provides a crucial roadmap for energy transition, highlighting that simply deploying renewable generation isn't enough. Designers and engineers must consider the systemic requirements for grid stability, including storage solutions and transmission infrastructure, to enable a fully decarbonized energy system.

06

What This Means for Your Design

To make Australia's electricity 100% renewable, we need lots of batteries (like pumped hydro) and better power lines connecting different areas. This will keep the lights on even when the sun isn't shining or the wind isn't blowing, and it won't cost too much extra.
