International locations all over the world are looking for revolutionary options to scale back carbon emissions whereas assembly power safety and financial growth wants. From rooftop photovoltaics (PVs) to offshore wind, inventive power technology sources have solved challenges related to typical renewable power sources comparable to land use restrictions and geographical constraints.
For nations with plentiful photo voltaic useful resource potential and restricted land availability, floating PV, or FPV, has emerged as a possible clear power resolution. In a first-of-its-kind evaluation, Nationwide Renewable Power Laboratory (NREL) researchers, funded by the laboratory’s partnership with the US Company for Worldwide Improvement’s (USAID) Regional Improvement Mission for Asia, accomplished an evaluation of FPV potential for the Affiliation of Southeast Asian Nations (ASEAN).
The report, Enabling Floating Photo voltaic Photovoltaic (FPV) Deployment: FPV Technical Potential Evaluation for Southeast Asia, estimates the technical potential for the ten ASEAN nations and is coupled with an FPV information set that’s publicly accessible by the USAID-NREL Partnership’s Renewable Power (RE) Information Explorer software.

Untraditional Options for Conventional Calls for: The Case for Floating Photovoltaics in Southeast Asia
Whereas conventional renewable power sources (photo voltaic arrays, wind farms, and many others.) are efficient forms of power technology, they usually include land-use challenges and issues.
In contrast, FPV arrays are located on water our bodies comparable to lakes, reservoirs, or water remedy ponds, the place they are often put in alone or together with hydropower dams. This technique of set up eliminates land use issues and makes use of areas which will in any other case go unused for power technology. That is notably of curiosity in instances the place hydropower infrastructure is deliberate or already in place, and elevated frequency or severity of drought could elevate issues round electrical energy reliability.
Growing Power Safety
Such is true for Southeast Asia, a area with important current hydropower infrastructure but some issues round power safety in periods of drought and water shortage. Photo voltaic and hydropower are complementary power assets, and FPV has the potential to agency up power technology in periods of drought and low reservoir ranges.
“Whereas we will’t generalize about Southeast Asia as a complete, one factor that’s principally universally true of the area is that it has a longtime community of hydropower technology websites. FPV can assist these sources as water ranges fluctuate to make sure grid stability,” stated Evan Rosenlieb, a geospatial information scientist at NREL who carried out the useful resource and technical potential evaluation for this venture.
“Moreover, a lot of the area is roofed by rainforest ecosystems,” Rosenlieb stated. “Siting PV on water could be a technique to improve renewable power technology with out deforestation.”
The Meals-Water-Power Nexus
Moreover, Southeast Asia is exploring different water-based options comparable to aquaculture—a way of farming the place aquatic creatures comparable to fish, crustaceans, and others are raised on managed water environments. Aquaculture websites current distinctive alternatives for FPV deployment and advantages.
“Together with its different co-benefits, FPV can play an vital position in bolstering meals safety in Southeast Asia by incorporation with the area’s fast-growing aquaculture business,” stated Prateek Joshi, NREL power engineer and lead writer of the report.
“This rising mixture of aquaculture and photovoltaics, generally known as AquaPV, can permit nations to colocate power and meals manufacturing on current pure or artificially created water our bodies whereas minimizing the general environmental impression of each sectors,” Joshi stated.
Assembly Renewable Power Objectives
International locations throughout Southeast Asia have bold renewable power technology objectives that FPV might help make a actuality. Collectively, ASEAN has set a goal of 35% renewable power put in energy capability by 2025, which has spurred these nations’ pursuits in aggressive and inventive options, like FPV growth.
“FPV is an choice that may permit many of those nations to benefit from high-quality photo voltaic assets to fight challenges comparable to land availability or rugged geographies that may make siting conventional renewable power sources troublesome,” stated Sika Gadzanku, the NREL power expertise and coverage researcher who led the event of this evaluation. “In addition they supply resilience alternatives in areas that use loads of hydropower however are dealing with droughts and important modifications in rainfall patterns.”
Figuring out Technical Potential and Creating Information for All
“Southeast Asia leads FPV deployment, and Thailand is rising as a serious participant on this area. Our FPV work has actually been demand-driven—a number of nation companions and builders expressed their curiosity in FPV and in flip, we launched into our first Southeast Asia-specific FPV evaluation 4 years in the past,” Gadzanku stated.
Gadzanku is an rising professional in FPV analysis and growth. Up to now 4 years, she has totally examined FPV growth in Southeast Asia, together with a 2021 report detailing boundaries to FPV deployment and a 2022 evaluation of the operational advantages of FPV-hydropower hybrid programs.

Constructing off earlier FPV research, the NREL crew used current information on waterbodies, infrastructure, and power assets to find out which waterbodies confirmed the very best potential for FPV growth. They discovered that each one the ASEAN nations have important potential for FPV power technology.
As these nations look forward to start growing FPV initiatives, information will likely be vital for his or her decision-making. To assist builders, policymakers, and different regional stakeholders, the USAID and NREL groups made this technical potential information accessible by the RE Information Explorer software.
“Among the many 4 important information required for profitable FPV growth, website location stands out as some of the vital elements to contemplate on account of geographic variations in Southeast Asian nations,” stated Chatchai Mawong, assistant governor of energy plant engineering and building on the Electrical energy Producing Authority of Thailand.”
Correct and detailed information of the positioning location is essential, because it impacts the feasibility of venture growth in every location, in addition to expertise choice, venture prices and eco-friendliness.”
This information set is the primary FPV information to be added to RE Information Explorer, increasing entry to the forms of analyses Southeast Asian stakeholders can do to evaluate renewable power technology.
“This information will result in extra discussions and might inform selections on the potential position of FPV within the area. It wouldn’t have been potential with out all the prevailing work of earlier FPV research and former RE Information Explorer software growth,” Gadzanku stated.
“The information is publicly accessible and can be utilized by all types of stakeholders—power planners and modelers, builders, and researchers—to assist extra detailed FPV analysis actions and modeling and evaluation efforts.”
