Global Modeling Report: Wärtsilä’s Strategies Towards Global Energy Efficiency
On December 11, 2024, Wärtsilä held a Round Table Discussion on the Global Modeling study on the journey towards Net Zero Emission which was released simultaneously in all countries where Wärtsilä operates, including in Indonesia.
The results of the report entitled “Crossroads to Net Zero” were presented by Febron Siregar, Sales Director of Wärtsilä Energy Indonesia in a closed discussion which was also attended by Irwan Wahyu Kurniawan (Senior Geothermal Inspector, Geothermal Directorate, Ministry of Energy and Mineral Resources of the Republic of Indonesia), Ricky Faizal (Vice President of RUPTL Control of PT PLN Persero), and Alloysius Joko Purwanto (Economic Research Institute for ASEAN and East Asia) as moderator.
Wärtsilä’s global power system modelling presented in the report compares two pathways for the period 2025 to 2050 with the aim of reducing greenhouse gas emissions and limiting global warming in line with the Paris Agreement targets. In the first scenario, only renewables such as wind and solar, as well as energy storage, are included in the energy mix. In the second pathway, flexible power generation technologies that can quickly adjust supply to support the intermittent nature of renewables are also added to the system.
Strong action from the electricity sector is also critical to achieving the low-cost, low-emission energy transition targeted by the 2050 Paris Agreement. This includes accelerating the expansion of renewable energy by improving transmission systems, simplifying licensing, and accelerating the development of balancing technologies to maintain grid reliability and resilience. Electricity market reforms are also needed to incentivize flexibility such as the introduction of additional services and price adjustments that support renewable energy integration. In addition, the selection of future-proof balancing technologies and the use of natural gas as a transition fuel are important steps to support the decarbonization of the electricity sector and prepare infrastructure and policies that encourage the use of sustainable fuels.
