Ministerial Order No. 233/2026/1, of 26 May, has recently been published, establishing the tariff applicable to electricity generated by photovoltaic power plants during the additional five-year period set out in Article 3(3) of Decree-Law No. 35/2013, of 28 February (“Decree-Law No. 35/2013”).

By way of background, Decree-Law No. 35/2013 allowed certain power generation facilities to benefit from a guaranteed remuneration scheme (feed-in tariff), subject to the payment of an annual compensation to the National Electricity System (SEN) (see Articles 1 and 5 of Decree-Law No. 35/2013).

In this context, Article 3(1) of the same decree-law further provided that power generation facilities covered by remuneration schemes prior to Decree-Law No. 33-A/2005, of 16 February, would continue to benefit from those schemes for a period of 15 years (see Article 3(1)(b) and (c) of Decree-Law No. 35/2013).

Upon the expiry of that period, Article 3(3) of Decree-Law No. 35/2013 established that the relevant facilities would remain subject, for an additional five-year period, to a tariff to be determined by ministerial order. It is within this framework that the present Ministerial Order No. 233/2026/1 has been enacted, defining the tariff applicable during such additional period.

Accordingly, electricity generated by photovoltaic power plants falling within the scope of the aforementioned provision will now be remunerated under the general market regime, with no entitlement to the payment or subsidisation of any tariff, premium or additional bonus, nor to any other specific support mechanism (see Article 2(2) of Ministerial Order No. 233/2026/1).

This Ministerial Order came into force on 27 May.
