Measures
Pursuing a high renewable power share as a means to achieve climate goals
Renewable capacity has increased significantly across the globe amid climate change concerns. The CDPii has stipulated a 12 per cent RE target by 2025, which together with the energy efficiency measures proposed in the SET scenario, allows a 37 per cent reduction in emission intensity relative to 2005 levels.
The pursuance of such a high share of RE generation, particularly with solar PV, is feasible in the region. Wind energy is not viable due to the low wind speed in Iskandar Malaysia (IRDA, 2010). Iskandar Malaysia has abundant solar energy generation potential of 47.8 TWh, primarily available from vacant land in the region. The potential for residential and commercial/industrial rooftop installation is comparatively smaller but still substantial. LCOE calculations for different scales of solar installation, calculated based on Malaysia-specific system cost data shows that the LCOE of solar PV systems in all cases, is lower than the tariffs.
Other than solar PV rooftop installation, NEXSTEP proposes that distributed mini-grid generation be the priority option in ramping up the RE capacity within the Iskandar Malaysia region. As noted by the Energy Commission (2020), solar penetration into the central grid is limited to 24 per cent of the maximum peak demand. As such, a high RE capacity integration into the central grid from Iskandar Malaysia may possibly jeopardize central grid stability. However, further power analysis in examining the opportunities and barriers of a high RE capacity will be conducted, whereby battery storage may be a necessity at a high RE capacity.
