TEIA - Trusted Energy Interoperability Alliance

The TEIA difference for OEMs

TEIA solves these challenges by embedding trust directly into every device. Deploy your energy solutions anywhere with built-in security and compliance.

“We're making our products TEIA-compliant—because without a universal trust model, the risks outweigh the rewards.”

Key advantages for OEMs

Accelerate device deployments with built-in trust and verifiable assurance at scale.

Seamless integration

Design once, deploy everywhere.

Plug-and-trust approach accelerates time to market.
Embed cryptographic verification at the data layer.
Vendor-neutral compatibility across grids, platforms, or services.

Regulatory-grade compliance

Assurance you can prove.

Immutable audit trails for devices and operations.
Verifiable identity and attestation.
Cross-border compliance with verifiable ownership and certification.

Device security and trust

Secure and trusted by design.

Device-level cryptographic identity protection.
End-to-end data protection from device to cloud.
Zero-trust assurance without sacrificing connectivity.

How TEIA delivers trusted integration

By embedding security and interoperability directly into the data layer, every TEIA-compliant device inherits four interlocking layers of protection.

Identity

Cryptographic identity for devices, services, and platforms ensures only authenticated actors participate.

Secure messaging

Application-layer protocols deliver trusted, interoperable communication, independent of underlying networks.

Protection

Cryptographically secure packets in transit and at rest enable data integrity across vendors and clouds.

Key management

Interoperable key provisioning and management supports PKI, blockchain, and quantum-safe cryptography.

Why OEMs choose TEIA

OEMs that adopt TEIA not only ship secure, compliant devices but also gain a trusted seat at the center of the energy ecosystem’s future.

Interoperability without compromise
Works with today’s standards (OCPP, Matter, OpenADR, IEEE 2030.5) while preparing for tomorrow’s requirements.
Incremental adoption
Enhance existing product with TEIA libraries— no costly redesigns or disruption to current operations.
Global market alignment
Complements IEC, IEEE, and emerging regulatory frameworks, ensuring worldwide market access.

The embedded standard for energy

OEMs that embed TEIA today will be the ones powering tomorrow’s grids, markets, and platforms. Join a growing alliance of global leaders to deliver secure, compliant, and interoperable OEM solutions.
