Given our complete reliance on these systems, critical infrastructure such as utilities and banking/financial institutions, medical facilities, roads and bridges, and transportation systems must be maintained and regularly upgraded to prevent failures and risk to the public.
How can an aging infrastructure combat threats such as more demand, cyber threats and severe weather? Without modernization, the energy infrastructure remains vulnerable to potentially catastrophic failure. In this blog article, we share modernization strategies for legacy utility infrastructure with serial connectivity.
Modern infrastructure and utilities can connect to many energy sources, including renewables, which reduces emissions while also reducing disruptions from weather and natural disasters. To do this, modernized utility grids rely on cutting-edge IoT technologies. These technologies include advanced communications equipment and software to manage and track infrastructure.
Utilities have to maximize the lifespan of their built infrastructure. Because of the expense of updating it, any infrastructure built must last around 40 years. The U.S. government's investments in power infrastructure mean many utilities have to find ways to modernize the management of their existing infrastructure.
A modern energy utility system incorporates several initiatives. First, it embraces IoT, smart meters and modern communications infrastructure. Modern energy utilities also embrace new forms of electricity generation such as renewables. Finally, modern energy utilities design new ways of distributing energy through updated infrastructure.

Part of modernizing utility infrastructure must include combatting cyberattacks. Could a cyber-attack shut down the power grid? Power and water utilities are the most at risk for cyber-attacks because many don’t have adequate cyber risk mitigation practices. Due to increased cyber risk, large investor-owned utilities have increased security investments. These investments range from $100 to $400 million — very big financial commitments to protect the utility infrastructure.
Security protocols and IoT provide utilities with several modern security options. Some of the strategies include:

It isn't financially practical to upgrade all the equipment in utility infrastructure. But enabling technologies can help by bridging new equipment and legacy devices. These technologies include IoT, and communications devices integrated with monitoring and management software.
Ways to modernize the utility infrastructure without replacing every piece of equipment include:
Connecting renewable energy sources safely to the existing utility infrastructure is a big challenge for power generation, transmission, and distribution utilities. There are many different laws in development, and they are changing frequently. Consider these strategies when connecting renewable energy sources to the grid:
There’s a ton of equipment in the field. Some of the infrastructure has network connectivity, but much of it still relies on serial ports. Think baseload and classic peaking plants, intermediate substations and distribution line monitoring equipment.
Yet, this infrastructure proves difficult to update because it is mission-critical and requires lots of testing and validation. Taking this equipment offline for maintenance is risky and time-consuming.
This is where Digi gateway and connectivity solutions can help. Our equipment delegates the communication function, making it easier to maintain and manage. And Digi provides a centralized management function that allows for seamless updates on thousands of units in the field, without impacting utility infrastructure operations.
Connectivity across all critical assets means increased reliability, real-time access to information, increased management flexibility, improved security through private networks, and even a seamless transition to 5G, when necessary.

5G provides high bandwidth and low latency for video and autonomous vehicle communications. But 5G also provides features that utilities need more such as the ability to segment data based on priorities.
Current 5G deployments serve high-population areas. In the next few years, radio chipsets will offer cost-effective connectivity for a lot of critical infrastructure. They’ll use lower frequencies for better penetration and range. They'll enable segmenting of different kinds of communications from each other. The integration of time-sensitive networking with cellular is something that's going to become more viable as we move towards 5G segmentations.
Digi’s CORE® plug-in LTE modem enables flexible deployment of various technology standards that make the most sense. For utilities with infrastructure designed to operate for up to 20 years once deployed, plug-in modems can provide the latest cell technology without making big changes to communications networks. This technology also allows for switching between public and CBRS private cellular networks.
