Long Duration Electricity Storage (LDES) cap and floor scheme

A cap and floor scheme ensures investors receive a minimum amount of revenue should their returns fall below a set threshold known as the “floor” to enable investment in LDES assets. Alongside this, the cap on revenue provides returns to consumers for their support, where LDES assets operate above the "cap" threshold. 
LDES refers to technologies that can supply electricity continuously for eight hours or more without recharging.
