The calculation is based on the REA remuneration on the right side of the table. The reference maize prices are derived from the REA payments using the German standard biogas plant. The reference price for silo maize is the maximum price that can be paid by the standard biogas plant at a given REA payment in order to cover costs. The equilibrium prices for wheat and grain maize were derived from this price for silage maize. If this price is reached or exceeded on the free market, silage maize is no longer competitive for biogas use
