DLMS UA is pleased to announce the signing of a Liaison Agreement with the STS Association, a global non-profit organization dedicated to promoting and maintaining international standards for the Standard Transfer Specification (STS).
STS defines a secure messaging system for carrying information between a point-of-sale and a meter and is widely used in electricity metering and payment systems. It is recognized internationally through IEC 62055-41, -51, and -52, and the association also manages a formal product certification program.
This collaboration marks an important step forward in aligning two widely adopted global standards – DLMS/COSEM Data Model and STS Credit Token technologies, to deliver stronger interoperability, enhanced prepayment capabilities, and increased value to the metering ecosystem.
The collaboration between DLMS UA and the STS Association focuses on strengthening both organizations’ positions in smart metering standardization by jointly promoting aligned visions and solutions, particularly in the area of prepayment. Together, the two associations will ensure that STS credit tokens can be seamlessly transported using the DLMS/COSEM data model and will develop the necessary specifications, mappings, and enhancements to support this integration within DLMS Generic Companion Profiles.
Both organizations will also work to synchronize their roadmaps so future developments in data exchange and token technologies evolve in a coordinated manner. They will also collaborate on market education and documentation to highlight the benefits of combining the DLMS data model with STS token standards, while expanding use cases to include water, gas, and heat metering in addition to electricity.
This liaison reinforces DLMS UA’s role as a global leader in interoperable data exchange. “By working with the STS Association, we will strengthen our prepayment offering, expand our reach into multi-utility applications, and ensure that DLMS-based systems remain at the forefront of secure, flexible, and future-ready smart metering solutions” added Sergio Lazzarotto, DLMS UA President.
