Traditionally, utilities have purchased, deployed, and at[1]tempted to integrate vendor “point [” solutions within the telecommunications domain. Most of these networks do not offer true interoperability. The convergence of ex[1]panding data (high bandwidth, low latency) and legacy trans[1]port systems demanded JEA develop a migration strategy. As the Director of Network & Telecommunications for JEA, I found myself in this dilemma: How do we support our lines of business in the leap from legacy technologies to Grid Modern[1]ization? The time for action is now; it is no longer a choice - it’s a necessity.

JEA had redesigned its data model for the aforementioned grid modernization efforts and we needed to undertake a sim[1]ilar initiative in regard to our networks. This would enable transport of exploding low latency data grid use cases that are common in our environment. JEA embarked on this effort over the past year to quantify and qualify its utility operations use cases based on the National Institute of Standards and Tech[1]nology (NIST) Framework and Roadmap of Smart Grid In[1]teroperability Standards, Release 4.0. We identified and char[1]acterized more than 100 utility operational Electric, and Water use cases for current and future state. Some of these core use cases included: Pole-Top Reclosers, Distribution Line Sensors, Faulted Circuit Indicators, Smart Regulators, Dynamic Water Consumption Monitoring, Capacitor Banks, Distributed Gen[1]eration Devices, Multiple-EV Charging Stations, and Smart Inverters. Our plan to use further leverage IIoT capabilities to increase our service reliability and provide our employees with real-time asset status information that offers multiple options depending on the type, location, and bandwidth needs of the installed sensors.

In the summer of 2021, JEA went to the marketplace with a solicitation to assist us in developing a Telecom Grid Modern[1]ization Strategy. The desired strategy would optimize a path toward a “should-be” wired/wireless network of the future, beginning with JEA’s current state network infrastructure, balancing a given set of constraints (e.g. budget, risk, security, obsolesce, resources, etc.) to arrive at an optimal future state network to support JEA. This strategy will migrate proprietary networks to a ubiquitous low latency, high bandwidth wired/ wireless platform which will transition JEA’s network opera[1]tions into the utility of the next decade.

Through a series of technology and business use case work[1]shops, we reviewed the following technology options focusing on interoperable, secure, resilient, scalable, and flexible solu[1]tions that would allow us to adapt to future modern technology. (see Figure 1)

During the development of our strategy, it became evident that a hybrid approach made the most sense, as there is no single solution that will meet all of JEA’s grid modernization needs. This model allows us to take an enterprise approach and lever[1]age “best-of-breed” technology. In addition, we will be able to meet our customers where their needs are, i.e. high bandwidth, low latency, edge compute, automation, video, analytics etc. Our goal is to create a vendor-agnostic architecture to meet our organizational requirements.

The development of the telecommunications strategy was based upon common industry principles that are critical to tele[1]communications. (See Figure 2) –

During the next nine to 12 months, we plan to run a pair of pilots leveraging core use cases to determine the best combi[1]nation of wireless and wireline solutions for JEA. Based upon the outcome of these pilots we will complete our enterprise in[1]tegrated grid planning and architecture design in conjunction with our business partners.

As JEA looks to modernize the grid, we need to keep in mind that we are not solving yesterday’s problems, but those of tomorrow.
