Grid Infrastructure and Renewables Integration for Singapore Energy Transition

Considering rising environmental concerns and the energy transition towards sustainable energy, Singapore’s power sector stands at a crucial juncture. This study explores the integration of grid infrastructure with both generated and imported renewable energy (RE) sources as a strategic pathway for the city-state’s energy transition to reach net-zero carbon emissions by 2050. Employing a combination of simulation modeling and data analysis for energy trading and advanced energy management technologies, we examine the current and new grid infrastructure’s capacity to assimilate RE sources, particularly solar photovoltaic and energy storage systems. The findings reveal that with strategic upgrades and smart grid technologies; Singapore’s grid can efficiently manage the variability and intermittency of RE sources. This integration is pivotal in achieving a higher penetration of renewables, as well as contributing significantly to Singapore’s commitment to the Paris Agreement and sustainable development goals. While the Singapore’s power system has links to the Malay Peninsula, the planned ASEAN regional interconnection might alter the grid operation in Singapore and possibly make Singapore a new green energy hub. The study also highlights the key challenges and opportunities associated with cross-border energy trade with ASEAN countries, including the need for harmonized regulatory frameworks and incentives to foster public–private partnerships. The insights from this study could guide policymakers, industry stakeholders, and researchers, offering a roadmap for a sustainable energy transition in Singapore towards meeting its 2050 carbon emission goals.
