As grid modernization accelerates, utilities are expanding the use of cellular connectivity to support distributed assets, field operations, and mission-critical OT environments. For many mid-sized utilities, security and visibility are no longer afterthoughts. They are foundational requirements that shape how cellular networks are designed, deployed, and managed from the start. In this customer-led discussion moderated by OneLayer, leaders from WEC Energy Group and Avista share how they are pursuing distinct paths toward secure cellular transformation while addressing real operational constraints. WEC Energy Group discusses its effort to build a centralized cellular strategy across multiple operating companies, beginning with a comprehensive understanding of existing deployments across carriers and business units. By establishing visibility and governance today, WEC is laying the groundwork for future private cellular adoption. Avista explores its hybrid private LTE approach, combining a private core with public carrier radio access to avoid the significant spectrum and infrastructure costs associated with a full private buildout. With Zero Trust principles guiding architectural decisions, Avista shares how prioritizing security early enabled collaboration with partners including Palo Alto Networks to support a secure and scalable OT connectivity model. Together, the panel examines lessons learned from managing thousands of cellular-connected devices across complex operating environments, balancing cost, operational efficiency, and cybersecurity risk while preparing for the next generation of utility networks. Attendees will learn:
How mid-sized utilities are implementing security-first strategies across hybrid and future private cellular networks
Practical approaches to centralizing visibility and governance across operating companies
How Zero Trust principles influence OT cellular architecture decisions
