STS WEBINARS
The recent Liaison Agreement between the STS Association and the DLMS User Association marks a pivotal step in the evolution of interoperable, secure, and future-ready metering systems. By aligning STS token technology with the widely adopted DLMS/COSEM framework, this collaboration is set to bridge the gap between legacy infrastructure and next-generation smart metering. The partnership reflects a shared vision to enhance interoperability, strengthen smart prepayment integration, and unlock greater value across the global metering ecosystem.
What does the liaison agreement mean for the long-term positioning of STS in a smart and interoperable metering landscape?
The STS–DLMS collaboration is not about replacing one standard with another but rather enabling standards to work together in hybrid utility environments. STS remains highly relevant due to its massive installed base and trusted prepayment infrastructure, while DLMS provides a pathway into smart, connected ecosystems. This partnership allows utilities to modernize gradually without abandoning existing investments.
Key Quotes
“The one thing we can’t avoid is change; this liaison ensures that utilities are not forced into disruptive transitions and can implement hybrid metering environments into the foreseeable future.”
“This liaison removes the notion of competition between standards and replaces it with coordination and synergy between different standards. STS will remain a robust, secure and widely trusted mechanism for prepaid revenue collection, whilst DLMS/COSEM enables secure 2-way communication and future-ready smart metering.”
How does integrating STS token technology into the DLMS framework enhance interoperability?
Ultimately, proprietary systems are a direct pathway to a potential vendor lock-in. Interoperability however enables utilities to deploy equipment and solutions from multiple manufacturers without compatibility issues. If interoperability is the goal, then standardization is the mechanism to achieve it.
Key Quotes
“We need to bring interoperability beyond compliance and into compatibility, do not get locked into a supplier, you must aim for a plug and play solution that enables scalability, seamless implementation and freedom of choice.”
“Proprietary innovative solutions that are adopted by the market eventually become standardized solutions. Standardization is not a barrier to innovation; it encourages suppliers and manufacturers to innovate on top of a proven foundation.”
How are STS tokens securely transported using DLMS protocols?
STS tokens themselves remain unchanged. The innovation lies in transporting the tokens through DLMS/COSEM gateways while maintaining full compatibility with existing STS vending and security systems. Utilities therefore gain both keypad and smart delivery methods.
Key Quotes
“An STS token is still an STS token; The only difference now is that you wrap it up in a DLMS/COSEM envelope, essentially giving you two distinct pathways to deliver your tokens”
How does the collaboration strengthen secure data exchange and prepayment functionality?
Cybersecurity has emerged as a critical focus area globally, especially as utilities move toward interconnected hybrid metering infrastructures. Both the STS Association and the DLMS User Association are collaborating to ensure future-ready, state-of-the-art security across electricity, water, gas and time-based prepayment metering systems.
Key Quotes
“Cybersecurity is becoming an increasingly critical investment for utilities, we are speaking about strategically designed infrastructure, and that cannot be taken lightly. Our combined responsibility is to make sure that standardized solutions offer state-of-the-art capabilities”
How are utilities protected while transitioning toward smart metering?
Utilities can take comfort knowing that they’re not being forced to replace their existing infrastructure. This liaison supports gradual modernization by extending the value of legacy STS systems while enabling smart metering adoption.
Key Quotes
“The priority is not to replace existing systems, but to extend their value. Utilities should have the flexibility to modernize at their own pace, striking that balance between stability and progress.”
