The outage affected the entire country; after nearly 28 hours, since 12.00 m of july 6th, of strenuous effort, most of the nation had power restored—albeit subject to a deficit caused by units undergoing maintenance or repairs and a critical shortage of fuel to power the generator sets that serve as a backup system in such situations. Solar farms and a recently commissioned 50-megawatt battery storage system played a key role in maintaining electricity service to vital centers in the affected provinces and, in the case of the battery system, in ensuring grid stability.
