Transpower is seeking feedback on our proposed treatment of potential limitation of thermal fuel availability in the Hydro Risk Curve (HRC) assumptions.
In late-2017 we received information from Genesis Energy regarding a potential limitation of thermal fuel availability. This a prompted a review of the treatment of thermal fuel, and specifically potential thermal fuel limitations, in the Hydro Risk Curves Input Assumptions. We have finished this review and have proposed a modified process for the treatment of thermal fuels in the HRC assumptions, described in the consultation document below.
As such we are seeking feedback on the treatment of this information with respect to the HRC assumptions, as required by clause 6.3 of the Security of Supply Forecasting and Information Policy [ pdf 425.37 KB ]. We ask you provide feedback no later than 5:00pm Friday 6 July.
