Public Policy Paper #6/2016: The "Pressure Cooker" effect of intermittent renewable generation in power systems

Author: Professor Simon Bartlett AM, University of Queensland

Key Points

  • Power systems have fundamental needs: load following, flexibility and dynamic response.
  • Increasing intermittent renewable generation in a power system has a “pressure cooker” effect and can involve an unaffordably high level of integration costs.
  • Every power system is different but, in most systems, the practical upper limit for renewables is around 40% of total electricity generated. This may be exceeded but it is likely to require a greater level of interconnection with adjoining power systems, more energy storage, increased recourse to demand-side management and regulatory changes.
  • The scale-up of intermittent renewables not only diminishes the robustness of a particular power system but can also magnify the short and long-term risk of investing in non-renewable generation assets and the power grid itself.
