Alfonso "Al" Gaba Cusi (Tagalog pronunciation: [ˈkusɪ]; born December 5, 1949)[1][2] is a Filipino businessman from Naujan, Oriental Mindoro who served as the 14th Secretary of Energy under the Duterte administration from 2016 to 2022.
Cusi and other Department of Energy officials face graft charges, neglect of duty, and grave misconduct before the Office of the Ombudsman over the buyout of Malampaya Philippines Pte.
His sweeping achievements in both the public and private sectors at this point were quickly recognized, earning him a Doctorate of Philosophy in Business from the Polytechnic University of the Philippines in 2007.
Returning to private business after GMA’s term, he initiated the fleet modernization of Starlite Ferries in 2011, setting industry standards.
On June 24, 2022, before his term as Energy Secretary ended, Cusi, through an affidavit of desistance filed in the Taguig City's Prosecutor Office, withdrew these complaints.
