Black Start back up technology picture

In today’s interconnected world, the reliability and resilience of power systems are crucial. Black Start and System Restart Ancillary Services (SRAS) play a vital role in restoring power after a widespread outage. At Simoco Wireless Solutions, we understand the importance of these processes and the potential of modern technologies like edge computing and advanced radio communications to enhance their effectiveness.

Understanding Black Start and SRAS

Black Start refers to the process of restoring a power station to operation without relying on the external electric power transmission network. In the event of a complete grid shutdown, Black Start capabilities are essential to bring power plants back online independently. Black Start resonates more in the Western world. SRAS involves a coordinated approach to restore the power system to full operation after a blackout in Australia. It encompasses a range of services, including frequency control, voltage control, and the provision of restart services by various generators and infrastructure elements.

The Seeds of Regeneration

The hum of electricity is the constant soundtrack of our modern world. But what happens when the music stops? In the event of a widespread blackout, the ability to restore power quickly and efficiently becomes paramount. This is where Black Start and SRAS capability emerges as the critical first step in grid recovery.

Black Start  and SRAS is the ability of a power station to initiate its operation without relying on an existing electrical grid. These self-sufficient heroes act as the starting point for bringing the entire grid back online after a major outage. Imagine a blackout triggered by a cyberattack or a natural disaster. Traditional power stations, dependent on the grid for their start-up sequence, become dormant giants. Black Start stations, however, possess the internal resources – like diesel generators or battery banks – to kickstart their own operations, becoming the islands of power from which the rest of the grid can be resuscitated.

Black Start in the Digital Age

The importance of them goes beyond simple functionality. The rise of edge computing and the processing of data at the periphery of the grid, adds a new dimension to black start capabilities. Edge devices, like smart meters and intelligent transformers, can collect and analyse real-time grid data. In a black start scenario, this data becomes invaluable.

The Role of Edge Computing in Black Start and SRAS

Edge Computing

Involves processing data closer to the source of data generation rather than relying on centralised data-processing warehouses. This decentralised approach offers significant advantages for Black Start and SRAS, particularly in terms of speed, reliability, and security.

Real-time Data Processing

Edge computing enables real-time monitoring and control of power systems. During a Black Start event, immediate data processing at the edge can facilitate rapid decision-making, reducing downtime and accelerating the restoration process.

Reduced Latency

By processing data locally, edge computing minimises latency issues, ensuring that critical commands and responses are executed without delay. This is crucial for maintaining stability and coordination during the intricate process of power restoration.

Enhanced Security

With edge computing, sensitive data can be processed locally, reducing the risk of cyber threats associated with transmitting data to central servers. This is particularly important in the context of critical infrastructure like power systems.

Advancing SRAS with Radio Communications

Radio communications are a cornerstone of resilient and reliable SRAS operations. Simoco Wireless Solutions leverages advanced radio technologies to enhance communication capabilities during Black Start and SRAS procedures.

Robust Communication Networks

Our radio communication systems are designed to withstand harsh environments and remain operational during emergencies. This ensures that communication lines between control centres, power plants, and field operators remain intact even when traditional communication networks fail.


Simoco’s radio solutions support seamless interoperability among various stakeholders involved in SRAS, including utility companies, emergency services, and government agencies. This coordinated approach is essential for efficient power restoration.

Scalability and Flexibility

Radio communications can be rapidly deployed and scaled to meet the demands of different situations. Whether it’s a localised outage or a widespread blackout, our solutions provide the flexibility needed to adapt to varying scenarios.

Enhancing Backhaul Communications

Backhaul Communications involve transmitting data from remote sites to central locations. In the context of Black Start and SRAS, efficient backhaul communications are critical for ensuring that data from edge devices and radio systems reach the central control centres effectively.

High-capacity Links

Our backhaul solutions offer high-capacity links to handle the large volumes of data generated during power restoration efforts. This ensures that control centres have access to comprehensive, real-time information to make informed decisions.

Reliability and Redundancy

Simoco’s backhaul communications are built with reliability and redundancy in mind. Multiple communication pathways ensure that even if one link fails, data can still be transmitted via alternative routes, maintaining continuous operation.

Integration with Edge and Radio Solutions

Our backhaul systems are seamlessly integrated with edge computing and radio communication solutions, creating a unified and efficient ecosystem for Black Start and SRAS. This integration enhances overall system resilience and performance.

At Simoco Wireless Solutions, we are committed to advancing the technologies that underpin critical infrastructure resilience. By integrating edge computing, advanced radio communications, and robust backhaul solutions, we provide comprehensive support for Black Start and SRAS operations. Our goal is to ensure that power systems can be restored quickly and efficiently, minimising the impact of outages on communities and industries.
