Under this lot the Supplier purchases biomethane from DCC as principal for onward sale into the gas market, so consideration flows from the Supplier to DCC rather than from DCC to the Supplier. The Supplier´s remuneration may arise through management or transaction fees, trading margins or spreads, deductions, retained amounts or other elements of the sale-price methodology, to be established through this competition. The estimated value stated for this lot is the gross market value of the biomethane expected to be transacted, stated inclusive of VAT at the currently applicable 20% rate; it is not an estimate of the Supplier´s remuneration and does not represent expenditure by DCC, and DCC gives no warranty as to future volumes or market prices.
