FlowX Selects ESG to Support ERCOT Operations With Titanium Billing, TMS, and Settlement Cost Allocation

Oct 8, 2026

ESG, a leading provider of software and services for the retail energy market, today announced that FlowX has selected them to support its ERCOT operations with Titanium Billing™, Transaction Management System (TMS), and Settlement Cost Allocation.

FlowX is an Option 2 ERCOT retail electric provider that entered the market in 2023, serving energy-intensive customers with a primary focus on bitcoin mining operations and large-load data centers.

After evaluating its existing platform and alternative solutions, FlowX selected ESG based on its ability to deliver hands-on transactional support, highly accurate and verifiable data, and advanced cost allocation capabilities critical for energy-intensive loads.

“Accuracy and transparency are non-negotiable for our business,” said Pei Hsuan Chiu, Chief Executive Officer of FlowX. “ESG demonstrated a clear ability to deliver validated data, reliable reporting, and direct operational support that allows our team to focus on strategic priorities rather than day-to-day issue resolution.”

FlowX was particularly drawn to ESG’s transactional support model, which reduces the burden on lean internal teams by directly managing Transmission and Distribution Service Provider related issues. Titanium Billing’s robust data validation and reporting capabilities stood out as a significant improvement, enabling FlowX to confirm usage accuracy, reduce re-billing, and access actionable insights without manual workarounds.

Tax accuracy was another key driver in the decision. ESG’s integration with CCH provides precise, compliant tax calculations across jurisdictions, addressing a long-standing operational pain point for FlowX. In addition, Titanium’s granular Settlement Cost Allocation functionality delivers per-meter and per-customer cost visibility, giving FlowX the clarity needed to understand true economics and manage margin with confidence.

“FlowX operates in a segment where precision, speed, and cost visibility are essential,” said Matt Hirst, CEO of ESG. “We are excited to support their ERCOT operations with a platform built to deliver accuracy, transparency, and operational efficiency at scale.”
