Exchange-filed company declaration - 600 MWac is operating, not the full planned project
Philippine solar-and-storage project declares 600 MWac commercial operation
What happened
Solar Philippines Nueva Ecija Corporation disclosed that 600 MWac of MTerra Solar Phase 1 began commercial operation on August 26 under a power-supply agreement with Meralco. The company said a final grid-connection certificate covers the safe connection and operation of 950 MWac of solar capacity and 825 MW of battery storage. Another 250 MWac under the same supply agreement remains planned for the coming months.
ACC context
The operating claim is company-reported. Grid-connected or energized capacity is not necessarily commercially dispatched capacity, and this review does not independently assess operating performance.
Why it matters
The 600 MWac milestone moves a substantial portion of the project from construction into declared commercial service and pairs utility-scale solar with grid-connected battery storage.
What to watch
- Verified dispatch, generation, storage, and reliability performance from the operating phase.
- The status of the additional 250 MWac covered by the power-supply agreement.
- Independent reporting that distinguishes commercial operation, grid connection, energization, and the full planned build.
