Decision: Feed-in Tariffs (FIT) scheme allowance methodology in the default tariff cap

Decision

This letter outlines our decision for calculating the Feed-in Tariff (FIT) allowance set out in Annex 4 to standard licence condition (SLC) 28AD of the electricity and gas supply licence from cap period six (April 2021 - September 2021) onwards.

We have decided to change our methodology. We have decided to use FIT scheme costs and demand on a 18-month lagged basis and uprate the scheme costs by the Retail Price Index (RPI) inflation to estimate costs in the upcoming period.

In reaching our decision, we have considered feedback from suppliers and set out our considerations in response to supplier views.
