Mauricio Peralta finished by highlighting some key aspects for successful RPT legislation; namely, that it is important to determine which renewable energy technologies and what size of generating plants will be covered by the law; to determine appropriate RPT tariff rate; guarantee the tariff rate over a specific period of time; determine an effective way of financing the RPT (through a governmental electrification fund or international donors); impose a priority purchase obligation (grid operators are obliged to connect RE producers to the grid and must transmit the electricity they produce).
