MADRID, July 28 (Reuters) - Spain's second-largest oil

refiner Moeve, formerly known as Cepsa, said on Monday its net

profit fell 19% in the first half of the year mainly due to the

impact of a massive power blackout in April in Spain and

Portugal on its refineries.

Its net income dropped to 324 million euros ($378 million),

while earnings before interest, taxes, amortisation and

depreciation fell 33% from a year ago to 733 million euros

($855.92 million).

The company attributed the core profit's decline mainly to

the cost of halting and restarting its two oil refineries during

and after the April 28 blackout. It can take one or two weeks

for such plants to be fully operational after shutdowns.

The Moeve refineries also halted for scheduled maintenance

during the first six months of this year, which further reduced

utilisation ratios.

The company did not release an estimate of the cost of the

outage, though rival Repsol, which operates five

refineries in Spain, said the blackout and other smaller

power-supply issues cost it 175 million euros in the second

quarter.

Owned by Abu Dhabi fund Mubadala and U.S.-based private

equity firm the Carlyle Group ( CG ), Moeve rebranded last year

to reflect its shift towards low-carbon businesses under an

8-billion-euro plan. It has sold 70% of its oil production

assets since 2022, including operations in Abu Dhabi and South

America.
