Rethinking Energy in Southeast Asia

It's time to #ShapeOurFuture with a clear roadmap to net zero

The Rethinking Energy in Southeast Asia series discusses key global and local factors that shape the energy sector. Driven by national energy strategies, falling installation costs of renewables, and public pressure against fossil fuels, countries in the region are gradually transforming their fossil fuel-based power generation fleets into more sustainable and diversified energy supply portfolios.

Learn more about the global energy transition and its impact on energy markets across Southeast Asia, and deep dive into the role of flexibility in high-renewable power systems in this new report.

Report summary

As the global shift to net zero accelerates, countries across Southeast Asia have an enormous opportunity to transition to clean power. By front-loading the deployment of renewables, Southeast Asian countries can accelerate decarbonisation and unlock myriad benefits. 

To illustrate the measures needed for cost-optimal paths to net zero, Wärtsilä has modelled the future power systems in Vietnam, the Philippines and Indonesia. 

Each country has different geographies, socioeconomic dynamics, and power systems, yet the modelling shows that net zero is technically and commercially feasible for each of them. 

Net zero is not a distant possibility. The models provide a clear roadmap for the rapid expansion of renewable energy in the next decade, to create carbon-neutral power systems by mid-century. A recipe which can be translated throughout Southeast Asia.

About the modelling

The modelling in this report is based on techno-economic optimisation of the energy systems of Indonesia, the Philippines and Vietnam. The optimisation finds the least-cost capacity mix to meet electricity demand in the future, while respecting a range of emissions scenarios. We have used PLEXOS, a leading power market simulation software, for the power system modelling results presented in this report.

The scenarios compare differing emissions reductions. The ‘Business As Usual - BAU’ scenario omits any new reductions – modelling the current plans in the three markets. The target date / deadline by which emission limits are met within the scenarios is based on the country-level net zero commitments, plus political pressure to decarbonise between 2050-2060.

Shape our future in

 

 

 

Shifting away from Southeast Asia’s current fossil-dependent system demands an unprecedented transformation in power sector strategies, power plant portfolios and operations. Policymakers need to play their role by shaping new markets – and by recognising the systemic cost of inflexibility, which is often hidden or spread out across fossil fuel portfolios.

Episode 3: Rethinking market mechanisms for flexibility

The integration of variable renewable energy into energy systems requires flexible technologies that can balance their intermittent output and ensure overall grid stability. In this episode, we look at flexibility from a market, planning and financial perspective and how we can incentivise greater investment in flexibility that will help accelerate the integration of renewables.

Episode 4: Rethinking energy storage systems

Installed energy storage is predicted to grow tenfold around the world in the coming decade, with 55% of that growth taking place in Asia Pacific. Find out what is driving this growth, as well as the challenges energy storage still faces in the region by listening to experts from Wärtsilä and the International Finance Corporation (World Bank).

Episode 6: Rethinking gas conversions

As more countries across Asia prioritise decarbonisation and the integration of more renewable energy into their power grids, gas conversions of power plants are becoming an increasingly popular solution. Find out how gas converted power plants are helping to reduce emissions and provide the grid stability needed for energy transition across the region.
