Singapore to Construct Two “Fast Start” Power Units for Reliable Energy Supply

Singapore, a bustling city-state known for its economic prowess and futuristic skyline, is taking a significant step toward bolstering its energy security. The Energy Market Authority (EMA) recently announced plans to construct two “fast start” power generating units, aimed at enhancing the reliability of the nation’s power system.

The Need for Fast Start Units

Singapore’s power units supply is critical for its residents, businesses, and industries. Any disruption can have far-reaching consequences. The new fast start units are designed to address this challenge by providing rapid response capacity. Here are the key points:

1. Capacity: The two units will collectively offer 100 megawatts of fast start generation capacity.
2. Timeline: By the second quarter of 2025, these units will be operational, ensuring swift response during unexpected events.
3. Ownership: PacificLight Power (PLP) has been awarded the right to build, own, and operate these units.

How Fast Start Units Work

Fast start units are capable of going from standstill to full load within a mere 18 minutes. This agility is crucial for maintaining a balance between electricity supply and demand. Imbalances can lead to supply instability and disruptions, especially when other generating units experience technical faults or unplanned outages.

Decarbonization and Energy Diversification

The new units play a pivotal role in Singapore’s energy transition. Here’s how:

1. Decarbonization: As Singapore moves toward a clean energy future, these units will contribute to decarbonizing the power sector.
2. Hydrogen-Ready: The fast start units by PLP are hydrogen-ready gas turbine units. This means they can potentially switch from natural gas to hydrogen, offering a cleaner alternative to fossil fuels.

Additional Context

In May 2023, EMA announced that its subsidiary, Meranti Power, would build two fast start open cycle gas turbine (OCGT) units on Jurong Island. These quick-response units, expected to be operational by June 2025, will replace Singapore’s existing OCGTs, which are over 30 years old. The existing units have a combined capacity of more than 400 megawatts.

In summary, Singapore’s commitment to energy security and sustainability is evident through the development of these fast start units. As the nation continues to grow and innovate, reliable power generation remains a cornerstone of its success.
