Germany is one of the countries with the highest electricity bills in Europe. If one third of the electricity bill is to be surrendered to the State Treasury from the German national grid, the government does not tax it as long as energy is produced by itself. If the self-generation is renewable energy, but also get additional government subsidies. To save costs, many German families have solar panels on their roofs, factories equipped with gas engines or wind power generation equipment.
According to statistics, Germany's annual electricity consumption of about 600 trillion watts, of which 50 trillion watts, or 8% of the power is produced by the people. In the industrial sector, the proportion of autonomous power generation has reached about 20%. Self-generation relies heavily on unstable resources such as solar and wind energy. How to control the balance of power generation and electricity has become a big problem. This requires the introduction of smart grid to regulate supply and demand. That is, each self-generator is both a producer and a consumer.
Self-generation Domestic electricity can be self-sufficient while at the same time selling excess electricity to the grid in a profitable way. "It is the right direction to decide consumption by power generation." When the wind or the sunshine is particularly strong, the power will be excess, which is very cheap, consumers will be able to switch on the electrical timely. If the power is tight, the price is high, consumers will moderately consider using less or perhaps tomorrow, electrical appliances.
All electricity generated is sourced directly through Power Exchange. When generating electricity, generators must consider how these are not needed by others. The cost of electricity storage is very high, and a lot of energy will be lost when switching. If you have excess electricity at that time, you may wish to switch off your generator.
