- Ubiik secured US$36.5 million in four Taipower AMI contracts since September 2024, covering 850,000 smart meter endpoints.
- The Nimbus 230 module combines Weightless LPWAN and NB-IoT with automatic failover, the company's first dual-mode product.
- Ubiik's cumulative AMI contract value in Taiwan exceeds $100 million across more than 2 million deployed meters since 2018.
- Each smart meter captures voltage, consumption, and power quality parameters at 15-minute intervals for Taipower's central data management system.
- Taipower's full AMI buildout targets approximately 13 million endpoints by 2035, with more than 1.16 million deployed through prior cycles.
Ubiik, a Taiwan-based developer of wireless communication systems for utilities, announced on July 22, 2025 that it had secured four new Advanced Metering Infrastructure (AMI) contracts from Taiwan Power Company (Taipower) since September 2024, totaling US$36.5 million. The contracts cover deployment of 850,000 smart meter endpoints, 750,000 using Ubiik’s proprietary Weightless LPWAN technology and 100,000 using NB-IoT, and mark the company’s entry into dual-mode metering with the simultaneous unveiling of its Nimbus 230 module. Ubiik’s cumulative AMI contract value in Taiwan now exceeds $100 million across more than 2 million meters since 2018.
What Is Being Built
The Nimbus 230 integrates Ubiik’s Weightless protocol stack with the NB-IoT modem from its existing Nimbus 220 module, enabling automatic failover between the two radio access technologies within a single hardware package. When NB-IoT coverage drops below threshold, common in dense urban canyons, basement meter rooms, and underground vaults, the module switches to Weightless on the unlicensed sub-GHz SRD band without meter replacement or field reconfiguration. Field deployment of Nimbus 230 across Taiwan is scheduled to begin in late 2025, with Ubiik also expanding Weightless AMI into the EMEA region, targeting the 863-870 MHz band used across Europe. Taipower’s full AMI buildout covers approximately 13 million metering endpoints by 2035, with more than 1.16 million already deployed through prior contract cycles.
Ubiik’s network currently processes more than 5 million meter readings per hour across live deployments in Taiwan. Each smart meter in the Taipower AMI system captures consumption data, voltage levels, and power quality parameters at 15-minute intervals, feeding a central data management system that utilities use to detect outages, identify theft, manage demand, and plan infrastructure investment. The Nimbus 230’s bidirectional communication supports firmware-over-the-air updates, meter parameter changes, and remote connect/disconnect commands without a truck roll.
Critical Perspective
Ubiik’s four AMI contracts with Taipower cover 850,000 endpoints, representing 6.5 percent of Taipower’s 13 million endpoint target by 2035, a pace that requires sustained contract awards over the next decade to complete the buildout at the current rate. All figures in this announcement originate from Ubiik’s own press release; no independent Taipower confirmation of contract terms, deployment schedules, or metering data accuracy rates is cited. The Nimbus 230 module’s NB-IoT failover performance in dense urban canyons and basement meter rooms is described by the vendor but has not been independently benchmarked in the Taiwanese deployment environment. Ubiik’s proprietary Weightless protocol stack creates long-term vendor dependency for Taipower: future hardware upgrades and radio spectrum management require Ubiik compatibility, unlike standards-based alternatives such as Wi-SUN FAN.
Why It Matters
Taiwan Power is deploying AMI at scale to support the island’s grid transformation as nuclear capacity retires and offshore wind and solar capacity ramps up. Dense penetration of smart meters with power quality monitoring capability gives Taipower granular visibility into voltage fluctuations, load asymmetry, and harmonic events that propagate from the growing base of inverter-based distributed generation. The dual-mode design of Nimbus 230 reduces the risk of meter communication failures in hard-to-reach locations that have historically required expensive infrastructure upgrades or signal repeaters.
TH Peng, CEO of Ubiik, said the Nimbus 230 gives utilities around the world a cost-effective, reliable fallback when NB-IoT coverage is lacking or unavailable. CTO Fabien Petitgrand said Weightless offers fully-acknowledged bidirectional communication with advanced radio resource scheduling for high network efficiency and capacity. Ubiik remains the largest AMI communication system vendor in Taiwan by deployed volume and will pursue additional tenders as Taipower accelerates its rollout toward the 2035 target.
