Renewable Energy
General
1. |
Solar energy is currently the most viable form of renewable energy for Singapore, and it forms part of our overall energy mix. However, intermittency and a lack of available land area to deploy solar photovoltaic (PV) systems limit its widespread adoption. As research and technological improvements bring down costs and improve the efficiency of solar PVs, solar energy could play a bigger role in Singapore in the future.

Improvements in manufacturing processes and technology have helped in lowering the cost of solar-derived electricity. However, factors such as fuel price movements and the costs of solar technologies and its deployment will ultimately determine if and when solar-derived electricity is commercially viable in Singapore.

Adopting subsidies such as Feed-in-Tariffs (FiT) distorts the energy markets and increases costs for consumers. Hence, it is important to price energy correctly and send the right price signals to both consumers and investors.
Instead of subsidies, Singapore has taken proactive steps to introduce regulatory enhancements to facilitate the entry of renewable energy when such technologies become commercially viable. The Government's support for renewables also comes in the form of funding for Research & Development to develop capabilities within the industry.

Net settlement' of the energy component means that consumers with embedded solar PV systems will be charged or paid based on:
i. Net withdrawal of electricity, when the total consumption at your premise exceeds the total generation of the solar PV system for each trading period*; or
ii. Net injection of electricity, when the total generation of the solar PV system exceeds the total consumption at your premise for each trading period.
*Any half-hourly period when electricity products are traded in the National Electricity Market of Singapore (NEMS).
