Decree-Law no. 189/88 (IPP Law)
The Independent Power Production (IPP) Law was introduced in 1988, revised in 1995 and 1999, for consistency with the implementation of a new regulatory framework for the electricity sector. The IPP Law allows for public or private entities or private individuals to generate electricity from renewable energy sources (including small hydro) and sell it to the grid, provided certain technical conditions for interconnection are guaranteed.
