    Houston, we have a transmission problem

    Variable Renewable Energy is making tremendous strides towards the predominant energy source in the NEM, but its voracious capital intensity is over-running existing transmission capacity. Consumers are faced with a $3.5bn transmission build cost over the next 20 years, which to return value relies heavily on the emergence of grid...

    The Victorian story of gas demand segments

    The Declared Wholesale Gas Market (DWGM) prices in Victoria have been on a rising trend since the start-up of LNG exports in 2015.

    Why invest in batteries?

    Batteries currently participate in the wholesale arbitrage and FCAS services (contingency and regulation). However, a lack of clarity in policies and regulations specific to batteries create uncertainties for investors. The key challenge is to determine and capture all possible battery value streams (current and future services). Stacked value streams increase...
