Mofiu and Neoenergia Announce Strategic Partnership to Accelerate Substation Digitalization and Grid Modernization

Guangzhou, China — Mofiu, a next-generation manufacturer of industrial wireless communications equipment, today announced a landmark strategic partnership with Neoenergia to accelerate the digitalization of electricity distribution networks and substation infrastructure. As global energy demands evolve and the integration of distributed energy resources becomes more complex, this collaboration aims to deliver mission-critical connectivity solutions that power the world's most demanding operational environments. The partnership aligns Mofiu's robust wireless hardware and network expertise with Neoenergia's expansive operational footprint to deliver end-to-end, future-proof connectivity solutions for energy infrastructure.

The Imperative for Grid Modernization in the Energy Transition The energy transition demands communications that are as resilient and scalable as the infrastructure they support. With energy networks becoming increasingly distributed across substations, microgrids, and renewable generation sites, operators face escalating connectivity demands ranging from deterministic latency to harsh-environment reliability. For energy providers like Neoenergia, upgrading legacy substations to support real-time data acquisition, predictive maintenance, and improved operational agility is no longer optional; it is a critical strategic imperative.

Melody, Chief Executive Officer of Mofiu, stated that industrial wireless networks must be as resilient as the infrastructure they protect. She emphasized that by partnering with energy leaders like Neoenergia, Mofiu is combining carrier-grade wireless technology with proven field engineering to help operators connect remote assets securely, close data gaps, and make faster, better-informed decisions.

Deploying the SG100 for Seamless IT and OT Convergence At the core of this digitalization initiative is the deployment of the Mofiu SG100, a rugged 4G router engineered to bring secure, resilient, and intelligent connectivity to the edge. Modernizing substation environments presents a unique challenge, as the physical world of industrial automation relies heavily on legacy equipment that communicates via established utility standards.

To bridge this operational technology and information technology divide, the SG100 supports multi-directional protocol conversion out of the box, accommodating widely used standards such as IEC 60870-5-101, IEC 60870-5-104, and DNP3. This capability enables legacy serial devices, including remote terminal units, protection relays, and smart meters, to seamlessly interoperate with modern IP-based SCADA and Industrial Internet of Things platforms. The platform integrates one RS232 and one RS485 serial interface, alongside two Ethernet ports for flexible local area and wide area network architectures.

Furthermore, the SG100 ensures that network continuity is maintained even in remote substation environments. The device features a field-proven cellular engine and a dual-SIM failover design that ensures uninterrupted service across varying carriers and fluctuating network conditions. Built to thrive in unforgiving environments, the router operates reliably in extreme temperatures ranging from negative forty to positive seventy-five degrees Celsius and supports a wide nine to forty-eight VDC input range, easily accommodating diverse industrial power systems.

Uncompromising Zero-Trust Security at the Network Edge As operational technology becomes more interconnected, the attack surface expands, making software-based security alone insufficient to protect critical national infrastructure. Mofiu systems are designed from the ground up with defense-in-depth security to ensure that vulnerabilities are mitigated before they can be exploited.

A cornerstone of the SG100's deployment within Neoenergia's infrastructure is its implementation of hardware Secure Boot. This feature establishes a cryptographic root of trust at power-on, verifying that the bootloader and firmware are authentic and unaltered before a single instruction is executed. This hardware-enforced chain of trust prevents malicious code from executing and safeguards the router against unauthorized firmware tampering and hardware cloning.

Ethan, Chief Technology Officer of Mofiu, noted that industrial networks and the threats against them are evolving rapidly, which makes a hardware root of trust non-negotiable for modern utility equipment. He explained that the company's roadmap is anchored in continuous innovation, ensuring that platforms scale and endure in the field with a hardened security posture.

Beyond the silicon level, the SG100 is equipped with the advanced WireGuard VPN protocol, offering operators a state-of-the-art cryptographic routing solution that significantly outperforms legacy technologies in both data throughput and reliability. This streamlined architecture allows the SG100 to establish secure, encrypted tunnels almost instantaneously, providing the low latency required for dynamic operational technology landscapes while ensuring the absolute integrity, availability, and confidentiality of industrial data.

Achieving Operational Excellence and Fleet-Scale ROI The economic and operational benefits of this partnership are expected to be transformative. By integrating Mofiu's advanced routers, Neoenergia can modernize substation and feeder communications to significantly enhance protection, automation, and fault location, isolation, and service restoration capabilities.

The ability to manage these devices at a fleet scale further drives operational efficiency. The SG100 enables administrators to define priority policies, leverage dual SIMs for carrier diversity, and tune watchdog thresholds to balance performance with cost. Secure zero-touch provisioning, policy-based configuration, and over-the-air updates reduce the need for costly truck rolls and manual on-site interventions. Mofiu’s solutions empower operators in the electricity sector to connect with confidence, where safety, uptime, and operational continuity are completely non-negotiable.

Through this strategic alliance, Mofiu and Neoenergia are setting a new benchmark for utility digitalization. From heavy industry to critical infrastructure, Mofiu stands as a trusted partner for organizations requiring secure, resilient, and high-performance wireless communications. The company's promise remains clear: to connect devices and possibilities with measurable return on investment and a stronger security posture.
