Transpower's fuel limitation consultation


Transpower is seeking feedback on its proposed treatment of potential limitation of thermal fuel availability in the Hydro Risk Curve (HRC) assumptions.

Transpower received information from Genesis Energy regarding thermal fuel limitations. Transpower expects this limitation, if modelled in the HRCs, would yield a material change to the HRCs. As such Transpower is seeking feedback on the treatment of this information with respect to the HRC assumptions, as required by clause 6.6 of the Security of Supply Forecasting and Information Policy.

Feedback is due by 5pm, 19 January 2018.
