Minimal. Self-consumption with surpluses. They are those installations that at certain times will send solar energy to the electricity grid, for example a home or industry without activity in the middle of the day. Within this modality we distinguish two important blocks: modality with surpluses covered by compensation. In this modality, the electricity supplier will compensate the energy discharged into the network in our electricity bill. This modality, without a doubt the most relevant in the rd, will be able to take advantage of homes and industries with installed powers of less than 100 kw. Modality with surpluses not covered by simplified compensation.
These installations are those, in principle greater than 100 kw, whose surpluses are going to be turned over to the network but under a e commerce photo editing sales regime, not compensation. The price of the energy discharged will be the one stipulated by the legislation of electricity generating installations. Self-consumption scheme net balance or consumption compensation regarding the energy balance, the royal decree speaks of the term "simplified compensation of surpluses", so that it is not the exchange of one kwh for another. The kw that is poured into the network at a given time is valued at the average price of that hour at that time and is deducted from the bill, therefore,
depending on the hours in which we are pouring into the network, the kwh will have more or less worth. The economic compensation will always fall on the energy term of the billing, keeping the power term unchanged, which depends on the power contracted in the supply and on having that power available. And the term of energy will never be negative , this royal decree aims to help the amortization of the installations but not to generate business or profits for the owner of the installation for what is not considered economic activity. In particular cases of self-consumption, it can lead
