Australia’s electricity market operator is considering new infrastructure options in the rollout of wind, solar and storage, in response to a 25-55% increase in the cost of overhead powerlines.

Its draft electricity network options report, released Friday, recognised the potential for local resources such as rooftop solar and battery storage to play a much larger role in the reliability and security of the power system, complementing transmission lines.
