The Philippines can smoothly transition to net zero by 2050, slashing emissions and carbon tax cost burden by over 20%, according to Wärtsilä

Wärtsilä Corporation, Wednesday 14th September 2022 at 10:00 Philippines Standard Time.

Power system modelling by the global technology group Wärtsilä has revealed that renewable-based power systems, backed by grid balancing engines and energy storage, would enable the Philippines to reach net zero by 2050, whilst cutting the levelised cost of electricity (LCOE) by more than 20% when accounting for likely future carbon taxes.

Wärtsilä’s modelling of the power system of the Philippines’ largest island, Luzon, shows that a combination of renewables plus flexibility, provided by balancing engines and energy storage, can reliably meet the region’s increasing power demand. 

Wärtsilä modelled two different scenarios: the “Business As Usual” (BAU) scenario – without an emissions limit – and a “Net Zero” scenario, where emissions were halved by 2040, before reaching net zero by 2050. Critically, when factoring in the International Energy Agency’s (IEA)’s upper forecasted carbon prices , the study shows that the LCOE in the “Net Zero” scenario is 23% lower than in the “Business As Usual” (BAU) scenario. This would equate to an annual saving of $6.5 billion USD. 

Luzon: A critical region for the Philippines’ energy transition: 
Luzon represents around 72% of the Philippines’ total energy generation and around 72% of the Philippines’ peak demand , compared to 14% in Visayas and 13% in Mindanao. The modelled pathway for Luzon, published in the Rethinking Energy in Southeast Asia report, can serve as a blueprint for major islands in the regions of Visayas and Mindanao as well. 

The Philippines has not yet explicitly communicated a net zero target, but its National Renewable Energy Program (NREP) sets out plans to power the grid with a 35% share of renewables by 2030 and 50% by 2040 .

The modelled scenarios reveal that flexibility, in the form of energy storage and balancing engines, is the crucial technological fix to enable renewable energy to become the dominant source of power. To put Luzon on course for its target of 35% renewables by 2030 and 50% by 2040, the island’s power system needs to rapidly accelerate the adoption of flexible balancing power plants, with 1.3 GW needed by 2030. By 2050, 14 GW of balancing power plants and 69 GW of energy storage would be required in Luzon’s power sector to achieve net zero emissions.  

Key findings:

  • In the “Net Zero” scenario, Luzon could cut its LCOE by 23% and avoid $6.5 billion USD per year in forecasted carbon taxes, compared to the “BAU” scenario, by 2060.
  • To align with the Philippines’ 35% renewable target, it should install 18 GW of solar capacity, 63% more than the 11 GW target set out in the country’s Power Development Plan (PDP). 
  • To support renewables, 6 GW of battery energy storage is needed by 2030. 
  • These actions reduce the need for Combined Cycle Gas Turbines (CCGTs) and coal, down by 5 GW to 12.7 GW by 2030, under the “BAU” scenario.  

With the right mix of balancing technology and renewables, Luzon can double the renewable generation in comparison to the “BAU” scenario, from 34% to 67% by 2040. 
By 2050, renewables can reliably provide 87% of Luzon’s total generation, up from 18% in 2020. Optimally, this renewable generation comes from 141 GW solar and 33 GW wind.   

David Kayanan, Financial & Market Analyst, Wärtsilä Energy, said:

“The results of the study clearly show that the opportunity of a generation is in reach for the Philippines’ energy leaders. In the Philippines, renewables can be levelled up using flexible capacity to serve the current load, while comfortably meeting rising power demand, and decarbonising at the lowest cost. 

“As countries return to the climate negotiations table at COP27, it’s clear that a net zero commitment in the Philippines would send a strong signal to investors, helping the country attract the needed investment to achieve this transition. On the flip side, without a net zero goal, the Philippines risks detaching itself from an increasingly climate-conscious global community and worsening its own exposure to climate change.”

“We hope that our report serves to assure energy leaders that, by creating a renewable and dynamic power system, the Philippines can increase energy self-sufficiency and mitigate climate risks, with the power sector continuing to support the economic development of the country."

The study results, published in the Rethinking Energy in Southeast Asia report, simulate the paths to net zero emissions in three major Southeast Asian power systems: Vietnam; the island of Sulawesi in Indonesia; and the island of Luzon in the Philippines.
