Process flow | The producer of electricity from renewable sources is obligated to apply for the connection to the grid. Information on planning, construction and operation of the connection has to be included in the application (3.2.1. Par. 2 DC 2014; 6.2.1. Par. 1 TC 2013).

Par. 3 DC 2014; 6.2.1. Par. 3 TC 2013). If all requirements are fulfilled the grid operator shall make a grid connection offer to the plant operator (3.2.1. Par. 5 DC 2014; 6.2.1. Par. 4 TC 2013). If the conditions of grid at the specific connection point are not sufficient for a connection of the plant, the grid operator with the support of the plant operator shall define jointly the required measure to reinforce or enlarge the grid to ensure a connection of the plant.
