Teldat Use Cases

Enhancing utility communications with policy‑driven routing, secure segmentation and adaptive connectivity across geographically dispersed grid assets.

Smart Metering Controls

Challenge

Normally a Utility has thousands of connected remote locations distributed across a geography with long distances between them. To increase this complexity some of those locations are unattended and located in complex spaces to access. Those locations are offering critical services to the company, and they also are supporting critical systems.

Besides the above-mentioned points, Electrical companies are also requesting quick, simple installation processes and competitive management tools with a view to not only controlling and configuring the initial installed base, but also any future devices incorporated into their Smart Metering networks. They need devices that can establish a trustworthy network for real-time communications, advanced networking protocols and guarantee service isolation.

Solution

Regesta Smart family devices offer next-generation communications for Smart Grid Meter deployments. Teldat devices have the latest technologies to meet all the Smart Grid Meter communications requirements but also provide state-of the art software and hardware. With PLC technology to connect Smart Grid meters and LTE with dual SIM (backup) they provide the optimal solution to fulfill the requirements.

Teldat’s solution allows you to create groups and templates to simplify this complex installation. Once the configuration is ready, a simple replication can be done for the installed base and for each new installation. After configuring the device and plugging in it is ready to work.

Why Teldat?

Teldat has leveraged its communications know-how to provide an in-house hardware design optimized to the unique needs of electrical companies during the past 15 years and more than 60.000 devices deployed. The Regesta Smart family has been designed to comply with strict standards on safety and performance in electrical environments, with a view to meeting the demanding conditions of processing plant locations.

Remote Control & Automation

Challenge

Remote control and automation of the electricity network play a significant role in the core business of Smart Grid deployments. The use of communications is therefore widely used as a guarantee of reliability, performance and security in the development of complex, sophisticated Smart Grid networks.

The need to comply with strict standards in electrical substations and harsh environment combined with the legacy communications with SCADA and RTU systems increase the complexity of the scenario.

Solution

Teldat’s Regesta Smart family are future-proof devices incorporating the newest technologies and constantly evolving to adapt to all kinds of scenarios, with the aim of simplifying management and controlling large-scale Automation deployments.

Regesta specific hardware design supports a wide operating temperature range and meets all electrical requirements for use in unattended locations with electrical hazards. All Teldat Smart Grid products have undergone comprehensive testing to ensure the equipment is reliable in the event of accidents, failures and adverse environmental conditions typical in these kinds of Smart Grid substations and transformation centers.

Protecting Smart Grids against cyberattacks

Challenge

Modern Smart Grids face increasing cyber risks due to the expansion of connected field devices, the convergence of IT / OT networks, and the exposure of remote, often unattended sites. Transformation centers, substations and cabinets distributed across wide geographies become attractive targets for intrusion, manipulation, or disruption.

Additionally, the geopolitical environment and the rise of coordinated attacks against critical infrastructures heighten the need for continuous protection. DSOs/DNOs must secure communications, enforce strong authentication, monitor protocol integrity, and ensure traffic isolation to maintain operational continuity and regulatory compliance across the entire grid.

Solution

Teldat’s Smart Grid communication platforms incorporate a multilayer cybersecurity architecture based on SASE principles and Next‑Generation Firewall capabilities. Out Zero Trust Network Access for OT (ZTNA for OT) solution ensures that only authenticated users, applications, and devices can interact with critical assets, reducing the attack surface across distributed sites. Deep Packet Inspection with SCADA protocol signatures reinforces protection by detecting anomalies, unauthorized commands, or malicious traffic patterns in real time.

Centralized management provides unified policy enforcement and continuous monitoring across PLC, cellular, and IP‑based links, enabling utilities to strengthen resilience and simplify large‑scale operations.

Why Teldat?

With long-standing experience in electrical environments and a proven installed base, Teldat delivers industrial platforms engineered to meet the cybersecurity demands of critical infrastructures. Teldat’s Regesta family holds High Category Certificate of Spanish National Security Framework (ENS).

Smart Grids using SD-WAN

Challenge

As Smart Grids expand and integrate thousands of substations, sensors, smart meters and distributed energy assets, utilities face increasing complexity in managing heterogeneous communication links. Many remote sites rely on mixed connectivity —PLC, fiber, cellular—making it difficult to ensure consistent performance and secure access. Traditional WAN architectures lack the agility to prioritize operational traffic, route telemetry efficiently, or maintain service continuity under link degradation.

In addition, the geographical dispersion of assets and the rise of cloud‑based OT applications intensify the need for dynamic, policy‑driven networking capable of adapting in real time. Utilities require an architecture that simplifies operations while ensuring reliable, secure, and predictable grid communications.

Solution

Teldat’s SD‑WAN solution enables utilities to unify and optimize communications across Smart Grid environments by orchestrating heterogeneous access technologies from a single intelligent platform. Dynamic path selection ensures that critical OT traffic always uses the most reliable, lowest‑latency links. Full support for both Layer 2 and Layer 3 services enables seamless integration with substation architectures, legacy systems, and modern IP‑based deployments.

Centralized policy control enforces consistent security, segmentation and bandwidth management across distributed nodes. With template‑based provisioning and continuous link monitoring, SD‑WAN simplifies deployment while maintaining high service continuity in remote locations.

Why Teldat?

Teldat combines industrial‑grade hardware with advanced SD‑WAN intelligence tailored for Smart Grids environments. Its platforms deliver policy‑driven routing, secure remote access and centralized orchestration, enabling robust and scalable communications across diverse topologies, including Layer 2 based services.
