MANILA, July 13, 2026 — Southeast Asia’s energy storage sector is witnessing explosive growth in 2026, with the Philippines and Thailand emerging as the core growth engines driven by stringent new national energy policies, surging power demand, and large-scale industrial cooperation. The two countries have rolled out targeted incentive and mandatory configuration rules, unlocking massive market potential for battery energy storage systems (BESS) and accelerating the region’s shift from traditional fossil fuel power to renewable energy dominance.
The Philippines has become one of the most rigid and high-potential energy storage markets in Southeast Asia following the implementation of landmark regulatory reforms this year. Under Department Circular DC2026-02-0008 issued by the Philippine Department of Energy in February 2026, all solar and wind power projects with a capacity of 10MW or above are mandated to equip energy storage systems accounting for no less than 20% of their installed capacity, with grid-forming capability as a mandatory technical requirement. This policy upgrade has completely standardized energy storage matching for large-scale renewable projects in the country, effectively solving the grid instability problem caused by intermittent new energy power generation.
To further boost industrial development, the Philippine government has introduced super-preferential industrial support policies, including zero import tariffs on energy storage equipment and a 10-year corporate income tax exemption for new energy and energy storage projects. These favorable policies have greatly reduced the operational costs of overseas enterprises entering the local market. Meanwhile, the country’s persistent energy supply pressure continues to drive market demand. Since March 2026, the Philippines has maintained a national energy emergency status amid tight power supply, coupled with high industrial and commercial electricity prices ranging from $0.18 to $0.25 per kWh. This scenario has not only promoted the rapid popularization of industrial and commercial energy storage for peak shaving and valley filling but also triggered a blowout in household energy storage demand, making portable and household battery storage products essential consumer goods for local families alongside air conditioners and refrigerators.
Thailand, another key player in Southeast Asia’s energy transformation, is advancing its energy storage layout with clear strategic goals and systematic policy support. According to the country’s updated national energy plan, Thailand has set a clear energy storage installation target of 6.2GWh by 2030, supporting the large-scale development of photovoltaic and wind power projects. The Thai government has launched a package of incentives including investment tax deductions and energy storage charging subsidies, significantly improving the return on investment (ROI) of energy storage projects. Benefiting from a peak-valley electricity price spread of $0.08–$0.12 per kWh, local industrial and commercial energy storage projects achieve an internal rate of return (IRR) of 15%–20%, attracting continuous capital inflows from global new energy enterprises.
Market cooperation between the two countries has ushered in a major breakthrough in mid-2026. On July 7, Philippine renewable energy developer Berde Renewables, backed by global infrastructure investor I Squared Capital, signed a three-year master framework cooperation agreement with Sungrow Power and its regional authorized distributor Solar Hive. The cross-border cooperation project covers the Philippines and Thailand, planning to deploy 200MW of solar inverters and 500MWh of battery energy storage systems within three years. This large-scale BESS deployment will effectively enhance the grid regulation capacity of both countries, optimize new energy consumption efficiency, and set a benchmark for cross-border energy storage resource integration in Southeast Asia.
Industry analysts point out that the dual drive of policy coercion and economic benefits has made the Philippines and Thailand the fastest-growing energy storage markets in Southeast Asia in 2026. Driven by mandatory energy storage configuration policies, the Philippine energy storage market achieved a new installed capacity of 400MWh in 2025, and the growth rate is expected to exceed 100% in 2026. Thailand’s steady policy iteration and superior project profitability are continuously attracting global energy storage brands to deepen local layout. In the context of Southeast Asia’s overall new energy expansion, the regional energy storage market is expected to exceed 50GWh by 2030, with the Philippines and Thailand contributing nearly 30% of the total market increment.
Despite the booming market prospects, the industry still faces challenges such as insufficient local financing channels and short-term supply chain fluctuations. However, with the continuous influx of international capital and the gradual improvement of supporting industrial chains, the energy storage markets of the Philippines and Thailand will maintain high-speed growth, becoming important strategic fulcrums for global energy storage enterprises to explore Southeast Asian blue ocean markets.
