Electricity Risk Curves Explanation

Risk curves have been developed for the purposes of reflecting the risk of extended energy shortages in a straightforward way, using a standardised set of assumptions.

Thermal Fuels  Validation

In late-2017 we received information from Genesis Energy regarding a potential limitation of thermal fuel availability. This prompted a review of the treatment of thermal fuel, and specifically potential thermal fuel limitations, in the HRC Input Assumptions. Since December 2018 when preparing the Hydro Risk Curves (HRCs), we have included an additional step to validate the thermal fuel consumption in the HRC modelling in light of known constraints to fuel supplies. This step was added to the process following consultation earlier in the year. For more information on this consultation, please contact the Security of Supply team at [email protected]

The modified process for the treatment of thermal fuels in the HRC assumptions is described in the document below.

On 1 April 2019, we held an industry teleconference to discuss the treatment of thermal fuels in the HRCs. A summary of this teleconference is included below.
