At-a-glance summary

The Market Stabilisation Charge (MSC) temporarily requires all domestic suppliers acquiring a domestic customer to pay a charge to the losing supplier, when wholesale prices fall considerably below the relevant wholesale price cap index1. The MSC is a temporary measure which came into effect on 14 April 2022 and will expire on 31 March 2024. 

What is the rate?

The MSC is a volumetric charge published weekly, split into two sub-charges; one for gas and one for electricity. The MSC is published after each Monday2 and reflects wholesale prices across the five preceding working days. The first MSC level was published on 12 April 2022, coming into effect on 14 April 2022.

Methodology and footnotes

  1. As of 23 May 2022 the MSC will be initially triggered when the wholesale cost falls more than 10% lower than the wholesale cost element of the price cap. The MSC also includes a derating factor, currently set at 85%. This de-rating factor determines the proportion of nominal hedging losses beyond the trigger point that will be covered by the MSC.

  2. When Monday is a public holiday, the updated charge value takes effect at 00:00 on the Thursday after the close of the preceding observation window. The previous charge remains in effect until the update takes place. See para 2.46 of the MSC guidance.

  3. Where Wpc is the wholesale element of the Price Cap, Wc is the wholesale cost of energy and Wt is the Losing Supplier Loss Trigger as defined in section 2 of the MSC guidance.
