REN activity in the coordination of connection and integration processes relating
to projects for Special Status Production (PRE) in the Public Service Power Grids
(RESP), particularly those which connect to the RNT, so as to ensure the effective
and safe integration of renewable energy sources into the National Electric
System (SEN), has focused on several different areas:

  • the planning of reception capacity for new production, the necessary network upgrading and the technical connection requirements;
  • the development of projects, the planning of work, the execution of work under the responsibility of REN and the monitoring of work under the responsibility of promoters;
  • participation and monitoring of inspections and the execution of connections to the network; the definition of protection and communication systems and command and control systems;
  • the definition of metering systems and border systems with the markets and the operational control of the execution of this operation through the dispatch control centres;
  • the forecasting of energy volumes produced and the resolution of management problems in the production of power required to satisfy consumption.

At the end of 2013, installed PRE power (not including large-scale hydropower)
connected to the RESP totalled around 6 800 MW. Within this figure, highlight
goes to the increase over the previous year of 114 MW of wind power from farms
connected to the RNT. This has been essentially due to the connection of new
wind farms and the expansion and remodelling of farms already in operation.

It is also worth emphasising that Decree–Law No 215 – A/2012 of 8 October
2012 revised the concept of special status production, defining it as follows: (in
accordance with Article18(1)):

’Special status production is considered to be the activity of production
licensed under special legislative schemes, such as the production of electricity
through cogeneration or endogenous resources, renewable or non-renewable,
microproduction, miniproduction and production that does not feed power into
the grid, as well as the production of electricity through endogenous resources,
renewable or non-renewable, that is not subject to a special legislative scheme.’
