Prime Infrastructure Capital, Inc. (Prime Infra) is strengthening its leadership team to accelerate growth across its water and energy businesses, following its recent acquisition of a majority stake in First Gen Corp.’s (FGen) gas subsidiaries.
The transaction, which closed Monday, gives Prime Infra control of four gas-fired plants — Santa Rita (1,000 MW), San Lorenzo (500 MW), San Gabriel (450 MW), and Avion (97 MW) — along with the proposed 1,200 MW Santa Maria plant and the Offshore LNG terminal.
With its expanded portfolio, Prime Infra is aligning leadership to strengthen growth initiatives and sustain operational excellence across its businesses, including Manila Water Company, Inc. (Manila Water) and the newly acquired gas operations.
“These strategic leadership changes ensure we have the right team in place to drive growth across our water and gas portfolio. Our focus remains on running strong operations and delivering essential infrastructure that supports the country’s development,” said Prime Infra President and CEO Guillaume Lucci.
Jose Victor Emmanuel “Jocot” A. de Dios will assume the role of President and CEO of Prime CoreGen, the subsidiary managing Prime Infra’s newly acquired gas assets, effective January 1, 2026. He will retire as President and CEO of Manila Water on December 31, 2025, with Roberto Jose “Boj” R. Locsin, the company’s Chief Administrative Officer and Chief Operating Officer for International Business, taking over the role.
De Dios brings extensive experience in energy. From 2001 to 2004, he was Undersecretary of the Department of Energy under then-President Gloria Macapagal-Arroyo, where he established the Natural Gas Office. He later chaired the Philippine National Oil Company – Exploration Corp. and led Australian oil exploration company Nido Petroleum Ltd. Prior to joining the Prime Infra Group, he was CEO of GE Philippines, managing diverse businesses including power generation, industrial solutions, and aviation.
Meanwhile, in his role as Manila Water Chief Administrative Officer and Chief Operating Officer for its International Business, Locsin oversees corporate administration and drives the company’s global expansion strategy across the globe. Locsin has been engaged with Manila Water since Prime Infra’s entry as a shareholder, leading systems implementation, opex rationalization, and operational performance initiatives, while helping embed a stronger performance-driven culture.
Before joining Manila Water, Locsin was Chief Executive Officer of Philippine Growth Terminals under global ports operator International Container Terminal Services, Inc. (ICTSI), where he led operations for Subic and Cagayan de Oro ports.
Earlier in his career, he served as Vice President for Strategic Services at a global biotechnology and pharmaceutical marketing consultancy and worked as a management and strategy consultant with Capgemini and Ernst & Young Advisory in New York. His expertise spans strategy development and execution, business transformation, mergers and acquisitions, and cost optimization programs.
Prime Infra, a Razon-owned and controlled company, continues to grow its portfolio through the development and operations of socially relevant critical infrastructure. Its energy portfolio spans natural gas production, gas-fired power plants, and pumped storage projects, contributing to the country’s energy security, grid stability, and reliable supply of indigenous resources.
