Puerto Rico, prone to blackouts, is advised to focus on energy security for critical infrastructure by leveraging natural gas (NG) to enhance grid resilience and reliability. NG can provide backup redundancy, fuel diversification, and essential ancillary services to ensure a stable grid. Distributed NG generation offers swift support for critical infrastructure and grid maintenance, preparing for potential disasters. By transitioning strategically to hydrogen, biogas, or green methanol, Puerto Rico can align with its net-zero energy goals. Establishing a natural gas distribution network supervised by PREB is proposed to ensure a smooth transition to a resilient and reliable energy future. Utilizing existing LNG terminals in the short term can offer immediate benefits, such as cleaner fuel for emergency generators. Embracing NG will enhance Puerto Rico's resilience, facilitate grid repairs, and lay the groundwork for a net-zero-emission future.
