1. Mandatory Storage Policies Take Effect
Southeast Asia‘s energy storage market entered a policy dividend period in 2026. Philippines DOE Circular DC2026-02-0008 requires renewable projects ≥10MW to co-deploy storage of at least 20% of capacity. Vietnam’s revised PDP VIII mandates storage ≥15% for new wind/solar projects. Thailand, Indonesia and others are advancing similar policies. These requirements translate directly into rigid procurement demand for storage equipment.
Global storage additions are forecast to reach 438GWh in 2026, with emerging markets growing 91%. SE Asia is expected to account for 10-15% of emerging market volumes, adding 6-10GWh in 2026 and cumulatively 100GWh from 2026 to 2030. Major projects： Philippines Terra (3.5GW PV + 4.5GWh storage planned, Phase II 1.05GWp PV + 1.2GWh storage under CEEC EPC). Indonesia‘s 100GW solar blueprint includes 80GW of 1MW PV + 4MWh storage microgrids across 80,000 villages, creating 320GWh of storage demand.
3. EPC Challenge： Fragmented Sourcing vs. One‑Stop Supply
Large projects face two core challenges： supply chain integration and schedule reliability. Sourcing modules, inverters and batteries from multiple vendors adds complexity, compatibility risks, and finger‑pointing during after‑sales. Mass‑delivery capability and reliable lead times are decisive. Many mid‑tier integrators hesitate because they cannot guarantee supply. That’s why a single‑source, factory‑direct supplier is becoming the preferred choice.
