Decarbonization of DKI Jakarta

Decarbonization of DKI Jakarta is developed using two approaches, namely non-linear
programming AIM-ExSS (Extended Snap Shot) and AIM-EndUse model based on GAMS
(General Algebraic Modeling System) v.23.3. The AIM-ExSS simulation gives thesnapshot projection of population, GDP, energy consumption (electricity and nonelectricity) and associated GHG emission (electricity and non-electricity). Moreover,especially for the power sector, the decarbonization pathway is developed by theAIM-EndUse modelThis poster presents the results of the Low Carbon Development
Strategy (LCDS) DKI Jakarta study presents various pathways in order toachieve a low carbon society in 2050, which includes the developmentof the power sector, energy, waste, and AFOLU (Agriculture Forestry andOther Land Use).
Low carbon development is important to be implemented in large citieslike DKI Jakarta, which is one of the metropolitan cities in Indonesia. The
city’s population, economic characteristics, and transportation conditionof DKI Jakarta will obviously impact GHG emissions levels. The purposeand objective of the analysis is to use a methodology or approachdeveloped to explore mitigation actions to achieve DKI Jakarta's Low
Carbon Society

Energy Demand and the Associated GHG emissions

Two projection scenarios have been developed :1. The business as usual (BAU)
2. The countermeasure (CM)Socio-economic
Socio-economic indicator assumptions: the city’s population at the same growth 1%
per year, and the average GDP annual growth rate is 6% (2015-2030), 5.5% (20302040), 5% (2040-2050).

The largest energy consumer in DKI Jakarta istransportation (2010). The energy demand growth ofthe commercial sub-sector will be similar to that of
the transport sector (2050)
A mix of energy supply in 2030 & 2050 is expected
to experience a shift where electricity and gas
consumption will be comparable to oil fuels.
Under the CM scenario, there will be a transition inenergy use from oil fuels to fuels with lower carbon
content (gas and biodiesel)
Mitigation actions of those two power plants (MuaraKarang and Tanjung Priok) located in DKI Jakarta,
which are connected to the JAMALI Grid, areconsidered as NPS (Non-Party Stakeholder)mitigation

GHG Emissions Reduction Target

2030

2050
32.31 Mton CO2e(30.3 % of 106.499 Mton CO2ein BaU)

55.41 Mton CO2e(29.2 % of 189.544 Mton CO2ein BaU)Key Findings
The major GHG emissions reduction is achieved under the CM scenario as the end-user efficiency improvement measures, fuel switching to fuel with lower carbon, change of transport mode,
deployment of advanced technology such as electric vehicles fueled using renewable sources, construction of street lighting using LED, promotion of solar PV system, efficiency measuresand fuel switching (oil to gas) in power plant, treatment of domestic solid waste, wastewater treatment, and increase of carbon sink through planting in DKI Jakarta.
The priority targets of mitigation actions by 2030 are aligned with mitigation actions in the Indonesian NDC roadmap. Furthermore, mitigation actions to achieve long-term targets (LCS) arealigned with the continuation scenario of NDC Indonesia
There are still rooms for improvement on mitigation action from the energy sector and waste sector to achieve GHG emissions reduction target in 2030 and 2050.
