13 REAL DECRETO 436/2004, del 12 de marzo de The PPA - For selling its production or excess, the owners of the installations to which the current Real Decreto may be applied, must choose one of the following to options: Sell the electricity to the power distribution company. In this case, the sales price of the electricity will be expressed in the form of the regulated TARIFF, constant for all periods of programming, expressed in Euro cents per kilowatt hour. The TARIFF is 3 * = 21,6216 EuroCent/kWh. It is allowed to burn 12% gas(*) as long as no electricity is generated. After 25 years the installation will receive 80% of that value. Sell the electricity freely in the market, through the offering framework managed by the market operator, through the framework of bilateral contracting, longterm or in a combination of all of thesse. In this case, the sales price will be the price obtained in the organized market or the price freely negotiated by the owner or representative of the installation, complemented by an INCENTIVE and, in its case, by a PRIMA, both expressed in Euro cents per kilowatt hour. The PRIMA is 2.5 * = 18,018 EuroCents/kWh plus an INCENTIVE of 0.1 * = 0,72072 EuroCent/kWh. It is allowed to burn 15% gas(*) without time restriction. (*) Burning gas is only allowed to maintain the temperature of a storage
