|Starting from 1 April 2020 households no longer have to pay the variable part of MPC for the electricity transferred to and received back from the network. It has become even more beneficial to generate electricity and transfer it to the network – bills for consumed electricity get smaller, installed microgenerators pay off faster and generation of green energy will develop more rapidly.|
In order to generate electricity for your own consumption, you have the opportunity to install a micro-generator in the existing connection and connect it for parallel operation with the electrical network. The micro-generator connection is a service used by both households and business customers (e.g. farms) that choose to generate electricity from renewable sources, thus reducing the amount of electricity received from the electrical network. To ensure that the operation of the micro-generator does not interfere with the electrical network, it is imperative to secure the approval for its installation from Sadales tīkls.
A micro-generator is a machine used for generating electricity and the related equipment (inverter), which is designed for AC electricity generation of 1-phase or 3-phase voltage with the operating current of up to 16A (amperes). It corresponds to a power of 3.7 kW in a 1-phase electrical network and 11.1 kW in a 3-phase network. Micro-generator parallel operation mode provides two-way exchange of electricity between the user’s electrical installation and the electrical network (electricity may flow both from the electrical network to the user’s electrical installation and in the opposite direction).
Micro-generators are intended for production of electricity for own needs rather than commercial purposes. When households start producing electricity, they can become members of the NET settlement system – transfer the electricity they have generated, but have not used immediately and use the electricity that was previously generated and transferred to the network, when own generated electricity is insufficient.

Microgenerator connection implementation process
The microgenerator connection process is carried out in accordance with the procedure set forth in the Regulations Regarding the Terms of the System Connection for the Participants of the Power System (available in Latvian). In order to implement a microgenerator connection, the application for the Microgenerator connection must be submitted to Sadales tīkls. Before submitting the application, please do the following:
- choose a certified microgenerator inverter, which is compliant with the requirements of the EU (European Union) standards and recognised by Sadales tīkls*, (the list is available here, available in Latvian);
- assess the required production load;
- consult with the local building board regarding its requirements for microgenerator installation.
