Manufacturing bears the largest estimated losses as Batam businesses recover from widespread blackout.
Batam’s prolonged power outage has raised major economic concerns, with an initial assessment estimating hundreds of billions of rupiah in potential losses from disrupted industrial production and business activity during a 12-hour blackout on October 12.
Blackout Losses Estimated at Rp233.5 Billion
A widespread blackout that disrupted Batam on Monday, October 12, 2026, is estimated to have caused potential economic losses of between Rp233.5 billion and Rp233.9 billion, according to figures reported by local and national media. The estimate covers the impact on industrial businesses and the trade and service sectors over approximately 12 hours, rather than a finalized audit of total economic losses.
Manufacturing Accounts for Major Share
Manufacturing was identified as the largest contributor to the estimated losses. Economic calculations cited after the blackout put lost manufacturing production at about Rp107.4 billion, reflecting the sector’s major role in Batam’s economy. Manufacturing accounts for roughly 56 percent of the city’s gross regional domestic product, according to the assessment.
Factories Face More Than Lost Production
The financial impact was not limited to machines stopping. Suyono Saputra, chairman of the Batam branch of the Indonesian Economists Association and vice chairman of the Batam Chamber of Commerce and Industry, explained that factories could still face labor costs while production was suspended. A factory employing 500 workers, for example, could lose an estimated Rp300 million to Rp400 million during a 12-hour production halt.
Damaged Materials Add to Costs
Businesses may also face additional losses from damaged materials and restarting specialized production facilities. Suyono cited electronics products undergoing high-temperature processing as an example of goods that could become unusable during a sudden outage. Clean-room facilities may also require several hours of sterilization before operations resume. According to the preliminary calculation cited by Terasbatam, damaged materials and technical recovery accounted for an estimated Rp32.2 billion, while disruptions to services, malls, hotels, and ports contributed an estimated Rp60.3 billion.
Batam Industries Depend Heavily on Power Grid
The blackout also highlighted the reliance of Batam’s industrial operations on the electricity network. Companies with their own generating capacity were relatively less affected, while numerous businesses operating across industrial estates remained dependent on the main electricity supply. The disruption therefore affected not only production schedules but also the recovery process businesses faced after power returned.
The estimated Rp233.5 billion loss illustrates the economic scale of a prolonged electricity disruption in an industrial city such as Batam. For Indonesian businesses and workers, reliable power directly affects production and operating costs. The disruption is also relevant to Singapore-linked businesses and investors with commercial or manufacturing interests in Batam, particularly where operations depend on continuous production and supporting infrastructure.
