WaterRock Energy team understand all the nuances of the Singapore power market through continuous client engagement with EMA and industry players in the past decades; we also have a long experience of modelling the Singapore electricity market.  

​

in Feb 2019 - April 2021, we were involved in the design of forward capacity market in Singapore; in 2021-22, we were engaged by the EMA to study the long term technology mix to achieve Singapore's long term carbon emission targets (including imports, hydrogen and CCS);  Since early 2022, we have been in a panel to help EMA evaluate the commercial aspects of power import proposals.

 Market Dynamics of the Singapore Power Sector

​​

• Market characteristics:

  • Even though the power sector is de-regulated, government continues to play important role for shaping the energy mix, investment and fuel procurement in Singapore. ​

  • Energy mix is dominated by gas capacity with similar efficiency since 2013. 

  • Gas procurement strategy and gas market dynamics have material impact on spark spread of CCGT plants in Singapore. 

​ 

• Investment Opportunities:

  • Imports: Power import is one of the key strategies that Singapore government has adopted to meet its CO2 emission target in the long term.  It is looking to import 3.5-4.0 GW of base-load green power from other countries by 2035.

  • Local investment: The government is actively seeking to get investors to plant local CCGT, solar and battery energy storage capacity. 

  • New technologies: The government is mulling to provide special incentives for pilot hydrogen (H2) facilities before rolling out big scale hydrogen infrastructure. 

​

• Key Themes to Watch in the near-term:

  • How will the gas procurement policy evolve/change given all the uncertainties in the coming years?

  • How much will the spot wholesale market prices and the retail prices fall from the unsustainable high level seen in 2022-2023. 

    • New local capacity is going to be commissioned in 2025-2027, including OCGT capacity invested by EMA and three new H-class CCGT units invested by Sembcorp, Keppel and PowerSeraya. ​

    • Some import capacity may start to flow to Singapore in 2024-2026, including the planned import from Peninsular Malaysia and Bulan Island in Indonesia. 

    • Singapore government has also introduced secondary price cap; and it is procuring vested contracts for the non-contestable customers, which can increase the contracted volume of the Gencos and reduce their incentives to bid aggressively to push up prices.

​​​Key Lessons from Singapore Electricity Market Liberalization are:

 

• Market reform can take a long time to reach the end-state desirable design and a phase-wise approach (like Singapore) has many benefits.

​

• Even though the first round of reform in Singapore is imperfect, it still provides useful and necessary learning lessons for the market stakeholders and the government.

​

• Robust reform on the market structure is critical to create an efficient and effective competitive electricity market that provide confidence to the investors that a level-playing field is created for everyone.  It can also reduce the scope and need for conduct regulation.​

​

• Commercial arrangement, such as vesting contracts, can be created to successfully mitigate the potential unduly exercise of market power of some of the Gencos in Singapore.

​​

• Retail competition can be rolled out in phases

​

• Flexibility has material values in a small market like Singapore.
