Article Summaries:
- Meralco PowerGen’s MTerra Solar project in the Philippines has achieved a key milestone: the 3.5‑GW solar‑plus‑storage Phase 1 site was successfully synchronized and energized with the Luzon grid on 12 February. The event, dubbed “The First Spark,” confirmed the system’s readiness and safe grid connection, marking the first time the plant will export power to the national network. As of the end of January 2026, the project hosts 1,288 MWdc of PV capacity and 622 battery units, the largest of their kind in the country. Phase 2 construction has already begun, with the first pile installed.
