Singapore increased the share of renewables in its power generation mix to a record high in May, according to reports citing the analysis of the latest market data.
This growth was driven by a steady rise in renewable energy imports and an acceleration in domestic solar power generation. The share of renewables in Singapore’s overall power mix rose to 2.58 percent in May, as reported by the National Electricity Market of Singapore.
Domestic solar generation in May saw its fastest monthly growth since March 2024, while renewable power imports climbed for the third consecutive month, reaching their highest level in over two years.
The city-state, which relies heavily on gas-fired power plants for about 95 percent of its electricity capacity, is working towards its goal of becoming carbon neutral by 2050. With limited domestic renewable energy resources, Singapore views regional electricity trade as a key part of its clean energy strategy.
From January to May this year, Singapore imported 122.7 million kilowatt-hours of clean electricity through the Lao PDR-Thailand-Malaysia-Singapore power trade route, which was launched in 2022.

This accounted for 0.52 percent of the country’s total power generation during that period. In comparison, no power was imported through this route in the same period last year, and imports only began in small quantities in the last quarter of 2024.
The share of imported renewable power in Singapore’s electricity mix rose for a third straight month in May, helping to offset some fossil fuel-based generation. The country’s total electricity output grew by 0.4 percent over the first five months of 2025.
Although the power imports came through the LTMS framework, all the electricity originated from Malaysia under a 50-megawatt supply agreement with Tenaga Nasional Berhad, Malaysia’s state utility.
Singapore’s Energy Market Authority had earlier doubled the capacity of electricity trade under the LTMS framework to 200 megawatts through additional supply from Malaysia. However, the terms for the continued supply of hydropower from Laos that would reach Singapore via Thailand and Malaysia are yet to be finalised.
