MADRID, March 17 (Reuters) – The upcoming report by Spain’s antitrust ​and energy watchdog ‌CNMC on the massive blackout that hit the Iberian Peninsula last ‌year ​will not ⁠assign blame for ⁠the outage, the watchdog’s chief said on Tuesday.

Spain and Portugal’s ​widespread blackout on April 28 left ⁠large swathes ⁠of the two ​countries in the dark ​for up to 10 ‌hours.

CNMC head Cani Fernandez told senators at a hearing that ⁠the report would include recommendations and conclusions, adding that ⁠the ‌regulatory and ⁠technical mechanisms at ​the ‌CNMC’s disposal were ​sufficient to ⁠manage the system adequately.
