Vivant Energy has secured a 15-year power supply agreement (PSA with the Province of Siquijor Electric Cooperative (PROSIELCO), adding 11 megawatts (MW) of contracted capacity to help stabilize electricity supply on the island after months of severe power shortages.

The agreement, signed on December 30 following a competitive selection process, covers electricity supply from Vivant Energy’s diesel power plant in Barangay Bogo, Maria, Siquijor. The contracted capacity will serve the municipalities of Larena, Lazi, Maria, San Juan, Enrique Villanueva, and Siquijor.

For PROSIELCO, the deal comes as the island seeks to recover from prolonged outages that disrupted households, businesses, and tourism operations in 2025. 

“We are excited about this partnership and we are hopeful that upon completion of the power plant, households and businesses will gain access to stable and dependable electricity,” PROSIELCO General Manager Glenn Galvan said.

Siquijor’s power constraints have drawn national attention. The province was placed under a state of calamity in June 2025 after outages stretched to as long as 20 hours a day at the height of the crisis, severely affecting essential services and the tourism sector. The situation was cited by President Ferdinand Marcos Jr. in his recent State of the Nation Address, where he called for urgent private-sector intervention to address chronic power shortages.

Reliable power is also increasingly critical for the island’s economic trajectory. Siquijor recorded the fastest gross domestic product growth in the Negros Island Region in 2024 at 7.9%, with economic output rising to PHP 13.78 billion from PHP 12.77 billion a year earlier.

“It has long been Vivant Energy’s thrust to prioritize areas that are largely underserved,” said Vivant Energy Vice President for Off Grid Solutions Eric Omamalin. “We believe progress starts where the grid ends. Beyond building a business, Vivant is helping build communities by delivering sustainable solutions that improve everyday living.”

What do you think this long-term PSA means for power reliability and investment appetite in other off-grid and island provinces?
