Empowering Choice and Innovation: GPT Expands EDI Capabilities into SoCal Gas Territory

Step into the next chapter of competitive energy innovation with GPT’s participation in SoCal Gas’s new Electronic Data Interchange (EDI) testing program. This initiative marks a major milestone in expanding customer choice and transparency across Southern California’s natural gas market.

GPT is actively working with suppliers who are providing natural gas to core accounts within the SoCal Gas service area. Through the Core Aggregation Transportation (CAT) Program, suppliers can now directly serve residential and commercial customers—bringing more competition, more supply options, and a pathway toward greener energy solutions.

Building on Proven Success

With years of experience managing large-scale EDI integrations for suppliers in the PG&E utility territory, GPT is leveraging its deep technical and regulatory expertise to support mass scaling of rate-ready and bill-ready billing within SoCal Gas’s expanding customer programs.

A Better Customer Experience

The single-bill option allows customers to receive one unified utility invoice—providing competitive supply pricing and green product options. This seamless experience simplifies billing and ensures continued reliability and convenience.

Looking Ahead

SoCal Gas anticipates that this new data exchange and billing program will launch in 2026, setting the stage for a more open and efficient energy marketplace.

GPT is proud to collaborate with suppliers and utilities driving this transformation. For partnership inquiries or technical questions about EDI integration, contact us today to learn how we can help streamline your participation in the SoCal Gas CAT program.
