This section looks into the maximum potential of solar PV and battery storage in Singapore based on several technical case studies. Given the small land area of Singapore, one of the most important considerations for the deployment of solar PV is the availability of space for panel installations. Indeed, land constraint and the resulting high land prices have often been cited as major impediment factors. As shown in Figure X, Singapore’s average per square meter land prices ranks as the second highest in Asia. The assessment for land space within this section, therefore, excludes ground-mounted and centralized plants on the basis that it is simply unrealistic and impractical for facility owners to be able to bear the exorbitant land leasing

Figure X shows the load curve for all three scenarios constructed, i.e. (1) power flow without any solar PV and battery system, (2) power flow with solar PV and battery system at Bus 8, and (3) power flow with solar PV and battery system at all load buses. As shown in the figure, the voltage at Bus 8 with a solar PV and battery system is enhanced by roughly 0.36% while power loss is reduced by 3.7%. For the latter, the effect is cumulative – with 9 load buses, the total power loss is reduced by 33.3%. This reduction is synonymous with energy efficiency improvement – thus, it can be concluded that energy efficiency for the third scenario has improved by a factor of one-third compared to the baseline …show more content…
A solar PV and battery system requires less capacity than its fossil fuel equivalent due to its full negative and positive capacity for regulation. As a fast response resource, battery storage is capable of charging and discharging energy much faster and more accurately. A thermal power plant, on the other hand, is slower to respond to the operator signal and is restricted by a minimum operating level requirement, below which operation and maintenance (O&M) costs would be affected
