Sumatra’s Largest Floating Solar Array Faces Community Concerns Over Environmental Impact
Table of Contents
LAKE SINGKARAK, Indonesia — A renewable energy project slated for Lake Singkarak, a joint venture between Indonesia’s state-owned electricity utility PLN and Saudi developer ACWA Power, aims to construct Sumatra’s largest floating solar power array by 2027. This ambitious project, however, is facing notable resistance from local communities who harbor deep-seated concerns about its potential environmental impact, stemming from a history of environmental disruption and a lack of trust in assurances from developers. The 50 MW project aims to bolster Indonesia’s renewable energy capacity, but locals fear for the endemic bilih fish.
A lake Haunted by the Past
For residents of Guguak Malalo ward, in the Tanah Datar district of West Sumatra province, the tranquil surface of Lake singkarak belies a history of trauma. Mardianis,a local resident,vividly recalls the devastating flash flood,known locally as galodoh,that struck 25 years ago.He remembers reading the Quran with his family when the disaster struck.
“If there’s heavy rain and it lasts a while, I won’t dare spend the evening at the food stall,” Mardianis said, reflecting the lingering fear that persists within the community.The disaster claimed dozens of lives and left a scar on the collective memory of the lakeside community.
Many attribute the flash flood to the construction of a hydroelectric plant, specifically the blast explosives used to create 17 kilometers (10 miles) of tunnels to channel water from the lake. This history of perceived environmental negligence has fueled skepticism toward new advancement projects on the lake. The community’s past experiences with the hydropower plant have eroded trust in developers’ promises.
Malin, a young resident, noted that the hydropower plant’s intake had altered the lake’s currents, making fishing more challenging. Ardinis Arbain, a hydrologist at West Sumatra’s Andalas University, supported this claim, stating, “many of the water sources were lost as of the tunnel that was built from Singkarak to Lubuk Alung,” referring to a town west of the lake.
Prior to the hydropower plant’s construction,access to electricity was limited. A development plan prepared by the Japan International Cooperation Agency (JICA) indicated that only one in five homes in the region, including West Sumatra province, had electricity. The Singkarak hydroelectric plant, with a capacity of 175 megawatts, was intended to power hundreds of thousands of homes in the province.
Floating Solar Farm Sparks New Concerns
The proposed floating solar array, a 50 MW project, is intended to bolster Indonesia’s renewable energy capacity. PLN chief executive Darmawan Prasodjo stated in December 2023 that the project “will be a revolution in the development of domestic renewable energy, and we hope that this project will contribute substantially to the development of the renewable energy business in Indonesia.”
However, the project has ignited concerns among local fishers who fear the installation of solar panels on the lake’s surface will decimate the population of bilih fish (Mystacoleucus padangensis), a vital source of income and sustenance for many families. The bilih fish is endemic to Lake Singkarak, making the community particularly sensitive to any potential threats to its habitat.
Helmi Kautsar, chief executive of AWCA’s local subsidiary, PT Indo acwa Tenaga Singkarak, attempted to allay these fears, telling state news agency Antara, “We will ensure that the presence of the Lake Singkarak Floating PLTS [solar farm] will not interfere with the natural habitat of the bilih fish.”
Despite these assurances, skepticism remains high. Ardinis, who was involved in an environmental audit of the Singkarak hydropower plant, noted, “Thay said it would have no impact, but that, in fact, was not the case.” He added that structural leaks in the tunnel wall had led to unregulated water accumulation and deprived some rice fields of natural irrigation.
Balancing Renewable Energy Goals with Community Rights
Indonesia has set ambitious renewable energy goals to meet its international climate change commitments. The government is preparing a new 10-year energy plan that could see around 70% of an additional 71 gigawatts of new capacity powered by renewables over the next decade.if triumphant, this would mean renewables accounting for around a third of the grid by 2035, up from just 12% at present.
However, the pursuit of these goals must be balanced with the rights and concerns of local communities. researchers have increasingly documented how land use for low-carbon energy projects disproportionately affects the poorest populations in low- and middle-income countries. Examples include communities displaced by a solar factory in Riau Islands province and those facing pollution from nickel mining sites.
The Columbia Center on Enduring Investment, a branch of Columbia University in New York, emphasized the importance of human rights in the energy transition in a 2023 policy briefing: “If policymakers do not effectively center human rights in the just energy transition, they may inadvertently cause widespread harm to Indigenous peoples and local communities.”
Openness and Community Engagement are Key
fabby Tumiwa, executive director of the Jakarta-based Institute for Essential Services reform, advocates for full transparency to ease concerns among the Lake Singkarak community. He suggests releasing the Amdal study, the Indonesian name for an environmental impact assessment, so that the community can understand the potential impacts of the solar farm.
Solar regulations stipulate that no more than 15% of the lake area can be covered by photovoltaic panels. The Singkarak solar farm plans to use 49 hectares (121 acres) of the lake, which is less than 1% of its surface area.
Andre Rosiade, a parliamentarian from the ruling party representing West Sumatra, has visited the site with PLN officials to mediate between the utility and local residents. He was quoted by state media as saying, “I guarantee that every investment in West Sumatra will have to benefit the community.”
Despite these efforts, concerns persist. Beyrra Triasdian, renewable energy lead at Trend asia, a Jakarta-based civil society association, warned, “it’s entirely possible that the endemic aquatic creatures and those that depend on the surrounding areas will be disturbed, or even disappear.It will also affect the lives of the Indigenous people in Lake Singkarak, which is a customary area that has been inhabited for generations and needs protecting.”
