Areva RIGs Must be Replaced to Ensure Continued CAISO Compliance

Folsom, Calif. – CAISO has set a deadline of May 7, 2017 to replace all existing SHA-1 security certificates on Remote Intelligent Gateways (RIGs) with a SHA-2 security certificate.

According to CAISO, RIGs built on the Areva platform cannot be certified with the Signature Hash Algorithm (SHA-2) standard and the associated 2048-bit encryption.

As of May 7, 2017, the SHA-1 SSL certificate on Areva RIGs will expire and will no longer interface with CAISO’s EMS. In order to maintain compliance, electric power generation resources that use an Areva RIG must replace that RIG with a compliant system, such as Trimark’s T1-S Gateway, that can accommodate a SHA-2 SSL certificate.

In December 2014, shortly after CAISO announced the change, Trimark began advising its customers that resources using the Areva RIG needed to upgrade their systems to ensure ongoing compliance. Trimark provided its customers an economical path to replace Areva RIGs.

Trimark’s T1-S Gateway was the first RIG to meet CAISO’s SHA-2 standard. Trimark’s T1-S Gateway RIGs have met that standard since it was first introduced.

Customers who need to replace an Areva RIG should contact Trimark
