Solar PV Project Development Market intelligence Southeast Asia

Southeast Asia presents patchwork of PV potential

Author: Brian Publicover, Solarplaza

Solar investors are increasingly looking toward the young and promising PV markets of Southeast Asia for new opportunities. The region’s key solar markets — Thailand, the Philippines, Malaysia, Singapore, Indonesia, Vietnam and Myanmar — had a big year in 2016, collectively installing about 1.58 GW of new PV capacity, according to statistics from the International Renewable Energy Agency (IRENA). Including Cambodia and Laos, the region’s cumulative installed PV capacity hit roughly 3.48 GW by the end of December.

Each country varies significantly in terms of development. However, Ben Attia, analyst for GTM Research, believes the rapid shift throughout the region toward competitive procurement will contribute to growth. He expects the Philippines to install 7,006.4 MW by 2022, followed by 6,079.1 MW in Thailand and 4,174.1 MW in Vietnam. With 13.3 GW (DC) of new solar capacity expected in those three countries over the next five years, GTM sees the region's cumulative installed capacity reaching 23.6 GW.

“However, this level of high growth is dependent on policy transparency and reform around feed-in tariff (FIT) rates,” Attia cautions.


Thailand added 729 MW of capacity in 2016, according to IRENA, bringing cumulative capacity to 2,149 MW by the end of December. But the outlook for ground-mount PV deployment remains uncertain, as the government continues to reshape its policies. And competition among developers to build new ground-mount PV projects is fierce, as new players are increasingly moving into solar, such as coal-mining giant Banpu, which recently announced plans to develop 300 MW of capacity.

The government planned to award 518 MW this year under its agricultural-cooperative PV scheme. IHS analyst Josefin Berg says this will provide “a bit of room” for ground-mount developers.

However, just 172 MW of capacity was awarded under the program this summer. Those projects will be built through the end of 2018, but plans for the remaining 346 MW are currently unclear.

“The ground-mount segment is going to be quite slow now,” laments Berg, who expects about 350 MW of new capacity in Thailand this year, down sharply from 2016.

A growing number of Thai companies are installing PV arrays for self consumption. In addition, local media outlets reported in September that the energy ministry will start allowing households and commercial buildings to sell electricity from rooftop PV arrays to the Electricity Generating Authority of Thailand at a purchasing of less than 2.6 baht per kilowatt-hour by the end of the year. And a new net-metering policy — expected in September — could help unlock even more opportunities in the C&I rooftop space, where companies such as Conergy see “significant potential.”


Malaysia — which installed 70 MW last year, according to IRENA — was overwhelmed by the response to its recent 460 MW solar tender. The auction — its second competitive tender for large-scale PV — received roughly 1.6 GW of submissions. Backed by a strong regulatory environment, Malaysia now appears poised to rapidly scale up PV development.

In a recent report, BMI Research acknowledges that in terms of scale, the potential for renewables deployment in Malaysia remains small in comparison to Thailand and Indonesia. However, the London-based firm it also says that the overwhelming response to the 460 MW auction positions the country as one of the “most attractive” renewables investments in Southeast Asia.


The Philippines installed about 633.1 MW in 2016, according to IRENA, cementing its status as one of the region’s strongest solar markets. However, the policy outlook appears to be stalled at the moment, as the government charts its next step forward.

In May, the Department of Energy (DoE) said that it would not proceed with a third round of FIT-backed solar projects. And although the DoE issued draft guidelines for a new Renewable Portfolio Standard (RFP) earlier this summer, policy momentum for solar remains stalled at the moment.

“The Philippines would in theory be best positioned for the highest short-term potential,” says Alexander Lenz, CEO of Conergy. “But discontinuing the FIT program without a transparent and working bilateral PPA market has left solar progress hanging.”

For now — without any supportive government policies in place for solar — Lenz expects that developers will increasingly build new projects via bilaterally negotiated PPAs.


PV investors are increasingly looking at Vietnam. A series of projects have been unveiled since the government’s announcement of a new FIT system earlier this year, including a 100 MW plan announced by India’s Tata Solar in April.

“Vietnam has significant immediate potential,” says Lenz.

The country’s framework to support PV deployment is almost complete, with a full PPA template expected by the end of this year. However, Dr. Oliver Massmann — co-general director of Duane Morris Vietnam LLC  in Hanoi — is concerned because a recent draft included “mistakes” that could render the agreements unbankable.

Nonetheless, Massmann expects solar to develop rapidly. The involvement of multilateral lenders such as the Asian Development Bank, for example, is starting to attract the interest of local commercial lenders, although access to finance remains an issue. And a number of supportive policies are drawing in unprecedented numbers of prospective foreign investors.

Massmann says investors should consider a build–operate–transfer (BOT) approach in Vietnam, but notes that there are also growing opportunities for equipment suppliers. “Vietnam is an untapped market for solar,” he says.


Indonesia is moving forward with auctions, following roughly 70 MW of capacity additions in 2016, according to IRENA. But the way forward remains treacherous due to policy instability.

“It’s one of those markets where there is a lot of potential for PV and renewables, but then policy is so unpredictable,” says Berg.

In June, utility PT PLN launched its first regional tender for 168 MW of solar in Sumatra. Winners will be selected by the end of this year. However, there are feasibility concerns, as projects will be awarded to developers that can bid below average local generation prices. That will be difficult in some parts of the country. In addition, issues related to domestic content requirements need to be clarified.

“It’s not a very transparent market,” concludes Berg. “There is definitely a way forward but it’s not straight.”

Some developers are directly negotiating PPAs with PT PLN. Most recently, Equis Energy finalized a 42 MW PPA with the utility. But the Singapore-based developer is tightlipped about how it secured a deal, beyond saying it is “excited” about the country’s 23% renewables target and plan to bring 35,000 MW of new generating capacity online by 2019.


A number of developers announced big projects in Myanmar last year, including a 220 MW installation by Bangkok-based Green Earth Power. However, a range of issues, including the country’s creaky grid network, could thwart such ambitions.

“The problem is multifaceted in Myanmar,” says Lenz. “For the short-term, the grid challenges and missing regulations relating to PV development and revenue streams will strongly limit implementation.”

In the short term, he sees potential to pair PV systems with storage batteries to address grid concerns and expand rural access to electricity. Direct consumption of rooftop-generated electricity, as well as diesel displacement systems, microgrids and other small installations are the most likely opportunities over the short term.

But given the country’s formidable solar resource, the future looks bright.

“It's only a matter of time until the dam breaks,” Lenz argues. “Myanmar will certainly come into the focus in the long-term.”
