Ayala’s South Luzon coal plant eligible for retirement

Early decommissioning of coal-fired power plants in the Philippines has advanced with utility Ayala Energy's 246MW South Luzon Thermal Energy eligible for the US-based Rockefeller Foundation's coal to clean credit initiative (CCCI).

The Rockefeller Foundation is a non-profit philanthropic group that creates and implements programmes in partnership with the private sector across different industries aimed at reversing climate change. Ayala has been working with the foundation to further shorten South Luzon's operating life from an original decommissioning date of 2040 to 2030. Doing so could result in the reduction of up to 19mn t of carbon emissions, Ayala said.

An assessment by the Rocky Mountain Institute, the technical partner of the foundation for its energy-related projects, found that an early retirement date of 2030 instead of the original retirement date of 2040 could yield positive financial, social and climate outcomes. But decommissioning by this date will require carbon finance.

Carbon financing will need to cover costs associated with the early retirement of the power plant's power supply contract, costs associated with 100pc clean replacement of the plant's power generation, plant decommissioning and transition support for workers affected by the plant's early closure, Ayala said.

Ayala's listed arm ACEN welcomed the plant's eligibility for the CCCI programme, as its retirement is part of the company's goal to have its power generation portfolio composed solely of 100pc renewable sources by 2025.

The Philippines' Department of Energy (DOE) said if successful, the pilot programme could serve as a basis for the development of other early retirement efforts as part of the country's plan to reduce carbon emissions. The DOE is seeking the early decommissioning of coal-fired power plants older than 20 years with a combined total capacity of 3.8GW by 2050, as part of the Philippines' transition to clean energy.
