ADB’s coal retirement plan may get caught in Southeast Asia’s coal lock-in

Some 45GW of additional coal in the next decade could pose risks to ADB’s 15-year plan.

The Asian Development Bank’s (ADB) energy transition mechanism (ETM) to retire coal-fired power plants in Southeast Asia could prolong the life of the plants, if it is “not designed correctly,” a report flagged.

Under the ambitious plan, the ADB seeks to buy high emissions coal-fired power plants in the region and retire them within 15 years. The ETM plan aims to retire almost 50% of coal-fired power plants in Indonesia, Vietnam, and the Philippines.

“Coal retirement will be crucial to Southeast Asia’s energy transition. However, this will be difficult without far-reaching market shifts, and there are numerous issues that policymakers and market participants must address to design any effective decarbonization plan,” a report, authored by Haneea Isaad, Research Associate, Institute for Energy Economics and Financial Analysis (IEEFA), read.

“IEEFA has long been focused on the issue of coal lock-in, particularly how the reliance on long-term power purchase agreements (PPAs) to support coal power investments restricts the ability of regional governments to shed high-emissions coal assets without severe financial damage.”

Based on IEEFA’s estimates, nearly 45 gigawatts of coal-fired capacity will be added in the next decade just by three Southeast Asia states. Of this, 17.5GW are from Vietnam, 20.7GW from Thailand, 6.4GW from the Philippines.

The three states also have a high share of coal in the power generation mix, according to the IEEFA. In 2020, coal accounted for 62.8% of the power produced in Indonesia; whilst it made up 48.1% and 57% of the power generated in Vietnam and the Philippines, respectively.

“If the ETM is not designed properly, there is a high risk that it would merely provide cash flows to ageing power plants nearing retirement already, or worse, prolong the life of polluting assets by giving them an additional grace period to retire,” Isaad said.

Vietnam has the largest coal-fired capacity addition in the region, with almost 29GW expected in the next decade. The IEEFA noted that most of this will be brought online by independent power producers that will further lock-in coal through binding PPAs and sovereign guarantees.

“IEEFA’s analysis reveals that in 2025, much of the planned capacity will be realized if plants currently under construction are brought into operation on schedule in Indonesia and Vietnam,” Isaad said.

“The scale of the lock-in becomes significantly larger, as the fleet’s size under ten years exceeds 25GW in Vietnam, 22GW in Indonesia, and 8GW in the Philippines.”

The two will collaborate to assess the role of green hydrogen in India’s energy transition.
This was met by renewables as well as coal, and gas generation.
It forms part of a 470MW battery project.          
About 120GW of new solar and wind capacity is expected in 2022.  
The agreement includes exploration of offshore wind projects.
The growth rate stabilises following an 8% increase in 2021.
This is a 10-fold increase from the Philippines grid-connected solar capacity.
32 nuclear reactors under construction are expected to bring 30GW in electricity per year.
Without banking power, the business model of solar power becomes unviable.
It is ideal for India because of its geographical location and the socio-economic opportunities it will offer, IEEFA Contributor Charles Worringham argues.
It will look into the development of a 1.2GW solar capacity in Indonesia.
The joint venture will operate under the brand Solar Radiance.
This is to support the increasing demand, according to Wood Mackenzie.
The joint venture is expected to start operations in the first half of 2022.
The product will allow coverage of consequential loss due to damages on property during PV installation.
