The Advantages of STS Interoperability in Smart Cities

The landscape of urban development is evolving rapidly, and the concept of using Smart-Meters to control energy distribution is gaining momentum just as quickly. At the heart of this transformation lies the concept of interoperability — the seamless integration and remote communication between various technological systems and services.

When you’re talking about energy transfer in a Smart City, interoperability offers a multitude of benefits that enhance the efficiency, security, and functionality of the Smart-Metering systems (Post-Payment and Pre-Payment) that are connected to the AMI (Advanced Metering Infrastructure).

?

Efficient Resource Management:

Interoperability allows different components of a smart city such as transportation systems, energy grids, and public services, to communicate and share data. This facilitates more efficient resource management by optimizing the use of energy, water, and other essential resources.

The Standard Transfer Specification, or STS, is a globally accepted open standard for prepayment systems that ensures interoperability between various manufacturers and service providers. There are many other prepayment standards out there, with an array of design and functionality options to suit your market’s needs. However, creating something ‘too customized’ can potentially lead you down the path of ‘Supplier Lock-In’ – Which is the very thing STS was created to prevent. The STS achieves this ‘true interoperability’ through a meticulous product certification process, to ensure that every system approved is compliant, so it can remain a ‘Simple, Trusted, and Secure’ solution for all your Prepayment and smart Prepayment requirements.

?

Improved Revenue Protection:

When it comes to managing resources, you also need to consider managing the risks associated with your ‘Smart Energy Systems’, or more specifically, the cryptographic keys used in the secure encryption and transfer of credit within your AMI. This is the exact situation where having a State-of-the-Art Key Management System becomes extremely valuable. This is one of the core services offered by the STS Association and features some very important security upgrades that make our system stand out. The ability to have complete control of your LIVE vending keys is of prime importance for the security of your prepayment revenue, and this is achieved through a ‘Key Refresh’ and ‘Key Revocation’ feature.

If your LIVE vending keys are ever compromised, your risk of revenue loss is very limited because you can now set the lifespan of a key (Key Refresh) and revoke the functionality of the compromised key (Key Revocation) at any time.

The Key Management Centre (KMC) encrypts the keys with an AES192 CCM (192 bit) and is a secure server facility with a fully operational backup facility, both of which can be accessed via an email gateway with 24/7 access throughout the year.

?

Promotion of Innovation:

The true interoperability achieved through STS certification opens procurement options from any approved supplier, which not only ensures innovation but encourages a collaborative ecosystem between all enterprises involved.

?

In conclusion, the benefits of a truly interoperable AMI within a smart city are multifaceted, ranging from energy efficiency and functionality to security and revenue protection. As cities worldwide continue their journey toward becoming smarter and more sustainable, prioritizing interoperability remains a key factor in unlocking the full potential of these technological advancements for the benefit of everyone.
