Tantalus to Deliver TRUConnect(TM) AMI and Distribution Grid Modernization Solutions to PenTex Energy

Deployment to strengthen reliability, enhance grid awareness and prepare for Texas' rapid load growth

Burnaby, British Columbia--(Newsfile Corp. - January 21, 2026) - Tantalus Systems (TSX: GRID) (OTCQX: TGMPF) ("Tantalus" or the "Company"), a technology company dedicated to helping utilities modernize their distribution grids by harnessing the power of data, today announced that PenTex Energy, a Texas-based electric cooperative, has selected Tantalus' TRUConnect™ Advanced Metering Infrastructure (AMI), TRUSense Gateways™, and TRUGrid™ Reliability Analytics—delivered through the Tantalus Grid Modernization Platform™ (TGMP™)—to enhance operational efficiency and member services.

PenTex Energy is refreshing its legacy AMI system to Tantalus' advanced data-centric platform. The new deployment will enable PenTex to access detailed, granular data across its network, integrate seamlessly with its existing SCADA system, and proactively manage grid operations as Texas continues to face historic growth and reliability challenges. ERCOT, the independent system operator for most of Texas, recorded an all-time peak demand of 85,559 MW in August 2024, and projects a 72% increase in peak load by 2030. Against this backdrop, PenTex is accelerating its investments in distribution grid modernization to ensure its members continue to receive safe, reliable and affordable power.

"PenTex Energy chose Tantalus as a key partner in our journey to build a modern AMI system and grid management platform," said Ryan Fuhrmann, Director of Finance and Office Operations at PenTex Energy. "What impressed us most was how quickly and easily we could access data to diagnose issues and improve member service. With just a few clicks, our teams will be able to identify problems, streamline manual processes and strengthen overall system reliability."

Through the deployment, PenTex will leverage the TRUSense Cellular Gateway, which delivers essential power quality data and enhances situational awareness. This functionality will be coupled with TRUGrid Reliability Analytics, which transforms raw data into actionable insights to pinpoint the root causes of outages and strengthen restoration strategies. Together, these capabilities will allow PenTex to remotely monitor and control devices across its network, shifting from a reactive to a proactive operational model. The result will be a more resilient grid, better equipped to withstand increasing load demands and extreme weather risks, such as high winds and winter storms.
