Benefits of self-consumption with compensation for the surplus energy.◾️ It gives companies the option to make the most of the surplus energy that is produced by their system.◾️ If your company closes on the weekends, for example, the energy generated by your system during this time can be injected back into the grid.◾️ This means that you will save more on your electricity bill and maximize the efficiency of your system.
What is it?
What is self-consumption with surplus compensation? Self-consumption with surpluses can be included in the compensation system, in which when a company does not consume all its energy production, the surplus energy is injected into the network and the company receives financial compensation for it.
Self-consumption with surpluses can be included in the compensation system, in which when a company does not consume all its energy production, the surplus energy is injected into the network and the company receives financial compensation for it.
Self-consumption with surpluses may not be covered by the compensation system, and occurs when a company that has not signed a surplus compensation contract, either of its own volition or because it does not meet the necessary requirements, discharges surplus energy into the distribution network and this energy will be sold to the electricity market, for which the company will receive an economic consideration corresponding to the regulations in force.
What types of self-consumption with surplus compensation are there? On April 5, 2019, the Government signed RD244/2019 in which the conditions of self-consumption are regulated. Defining two modes of self-consumption, self-consumption with surpluses and self-consumption without surpluses.
-Self-consumption with surpluses: Power generation facilities that, in addition to supplying energy for self-consumption, can inject surplus energy into transport or distribution networks. Therefore, the company is a consumer and producer of energy at the same time.
-Self-consumption without surpluses: This occurs when the photovoltaic self-consumption installation has an anti-dumping system that prevents surplus energy from being injected into the transmission or distribution network, so that all the energy generated is used by the consumer.
Within self-consumption with surpluses we find two modalities:
-Modality covered by simplified compensation: This option implies that your electricity supplier will compensate you in your monthly electricity bill for the excess energy that you pour into the network. The price paid for the electricity you feed into the network will be less than the energy you get from your installation for self-consumption.
-Modality not covered by simplified compensation: Installations whose surpluses are going to be injected into the network, but not under a compensation regime, but for sale; obtaining for the sale the price established in the electricity market. To do this you have to register as a producer.
Two other energy production options are also specified in the decree:
--Shared self-production: A consumer participates in a shared self-consumption when he belongs to a group of several consumers who are fed, after an agreement, with the electrical energy coming from production facilities close to those of consumption, associated with them. For example, it would be the case of industrial companies located in the same location, which would benefit from this more accessible self-production modality.
-Self-production by proximity: Carry out an installation of solar panels in an area close to the company, being able to take advantage of the energy generated.
In both cases, a toll must be paid for the use of the network and that the two points, both the generation and the consumption point, are connected to low-voltage lines that share the same transformation center or that do not have a greater separation at 500 meters.
