การเปลี่ยนแปลงอัตราค่าซื้อคืนพลังงานแสงอาทิตย์ ECIS ของสิงคโปร์

Singapore's Energy Market Authority (EMA) reports that average solar export compensation under the Enhanced Central Intermediary Scheme (ECIS) has fluctuated significantly over the past quarter as the Uniform Singapore Energy Price (USEP) responded to global LNG market shifts. Average payouts to residential solar prosumers ranged from SGD 0.04 to SGD 0.12 per kWh exported in Q1 2026, well below retail tariffs that range SGD 0.29–0.33/kWh. The data underscores Singapore's structural reality: with no land for utility-scale solar and limited rooftop area, the economic case for residential solar depends almost entirely on self-consumption rather than grid export. EMA continues to encourage hybrid solar+battery installations through the SolarNova program for HDB properties, where aggregated solar across multiple HDB blocks reduces town council common-area electricity costs by an estimated 30%. For private condominiums and landed properties, the National Environment Agency's Energy Efficiency Fund (EEF) provides grants of up to 50% for combined solar PV and energy efficiency projects. Industry observers expect Singapore's residential solar growth to remain modest in absolute terms but to increasingly shift toward solar+storage configurations that maximize self-consumption value.
