Market Update

The Company notes the recent UK Government announcements relating to: (i) the removal of carbon price support (“CPS”) from 2028; and (ii) the increase to the tax rate on the electricity generator levy (“EGL”) from 45% to 55%; and (iii) the intention to introduce the option for low carbon generators that do not benefit from an existing contract-for-difference (“CfD”) to bid for a wholesale CfD (“WCfD”) (the “Announcements”).

The Company does not expect any material impact on the valuation of the Company’s investment portfolio as a result of the Announcements. The Company’s independent electricity price forecaster had, in their long-term forecasts, already assumed the phasing out of the CPS alongside the increased alignment of the UK and European Union carbon markets. Further, such electricity price forecasts are below the level at which the EGL applies. The Company and its Investment Adviser will continue to review proposals relating to the WCfD as they are developed to assess the extent to which the WCfD would benefit any projects in its investment portfolio.
