Microgeneration systems
The Microgeneration is the production of electricity in renewable energy installations of low power to sell it to the public. There are two systems of production, the general scheme and subsidized. In the general scheme of the power connection is limited to 50% of the power already contracted in the purchase of electricity and up to 5.75 kW in the subsidized regime the power connection is limited to 50% power has engaged in contract purchase of electricity and up to 3.68 kW.

There are excellent reasons to invest in this type of installation, including deductions for income tax, clean energy and above all is a profitable investment, and the investment pays itself in six to seven years and has a rate of return on investment of about 13%.

Decree-Law n. º 118-A/2010 of 25 October (Portugal)

Simplifies the legal regime applicable to electricity generation through small power plants, called micro units, and proceeds to the second amendment to Decree-Law no. 363/2007 of 2 November and the second amendment to the Decree -Law no. 312/2001 of 10 December.
Systems minigeration
Miniprodução activity is small-scale decentralized electricity production, using for this purpose, the renewable resources based on a single technology, and delivering, against payment, electricity to the public, provided that there is actual consumption of electricity at the installation site and whose power grid connection is equal to or less than 250kW. The renumbering of miniprodução is divided into two schemes to choose from, the general scheme and subsidized regime. Where conditions are as follows:

  • General scheme:

    Power connection is limited to 50% of the contracted power with a maximum of 250 kW, it is necessary for the energy consumed in installation and use is not less than 50% of the energy produced by the unit miniproduction
    The sale of electricity in this system observes the rules established for the sale of electricity under the ordinary regime, ie at market conditions.

  • Subsidised Regime:

    In addition to the requirements for the general scheme, will also be mandatory that the following cumulative conditions:
    • Evidence provided, the date of application for inspection, conducting energy audit to determine the implementation of energy efficiency measures, with the following return period:
      • a)Tier I (up to 20kW) 2 years;
      • b) Tier II (from 20kW to 100kW) 3 years;
      • c) Tier III (100kW to 250kW) four years
    • Compliance with the measures identified in the audit should be reported annually to DGEG until its full implementation.
    • The sale of electricity in this regime obeys the two rates that are well distributed:
      • - Up to 20 kW, a reference price fixed at ? 250 MW / h for a period of 15 years;
      • - For powers between 20kW and 250kW, the regime depends on competitive mechanisms, ie, the reference tariff is based on the 250MW / h, and will select the entities that offer the best discount to the tariff, and the various applications for registration will be ordered according to this discount. This rate is guaranteed for a period of 15 years.

DECREE-LAW n. No. 34/2011 of 8 March (Portugal)

Establishes the legal regime applicable to electricity generation through small power plants, known as units miniproduction.
Windmills
A wind turbine is an integrated electric generator to the shaft of a wind vane, and that converts wind energy into electricity. It is a device that has quickly become popular for being a source of renewable energy and clean.
Isolated systems - are all systems that are deprived of electricity from the grid. These systems store energy in the turbine stationary batteries, enabling the energy consumption periods in that there is no wind, preventing the electrical power fails or when the turbine stops.
Hybrid systems - are all systems that produce electricity simultaneously with another source electroprodutora. This source may be of photovoltaic electric generators diesel / biodiesel, or any other source electroprodutora. In these systems have the same operation that we isolated systems, the only change is that the charging of batteries is made stationary for more than one generator.
Injection systems on the network - are all systems that enter the energy produced by them in the public grid.
