Teleport: Monthly Report

January 2026

Three top cybersecurity priorities

As we enter 2026, the digital layer of our energy system has become just as critical as the copper in the ground. The digitalization of energy infrastructure introduces powerful capabilities for trading and flexibility, but it also creates new vulnerabilities. At Withthegrid, we believe a resilient energy ecosystem must be built on a foundation of security and trust.

Based on recent events in the field, we want to share three top priorities to secure your operations in the coming year.

Teleport feature highlight: Participation in aFRR markets

The evolving conditions of the EPEX and imbalance markets might make it harder to consistently meet your financial targets. Because of this volatility, many of our partners are turning to the automatic Frequency Restoration Reserve (aFRR) market to capture higher margins.

The aFRR market requires quick communication with your assets that standard hardware often cannot deliver. The Teleport Gateway bridges this gap by providing the sub-second signal processing, ramp-rate control, and reliability required to participate. By using the Teleport, you remove technical barriers to premium balancing markets, allowing your energy trader to manage your assets for maximum return.

Questions about using the Teleport for aFRR? Contact us.
