Dear *|FNAME|*,
Six years ago, California Rule 21 adopted IEEE 2030.5, SunSpec started certifying IEEE 2030.5 devices (that also comply with Common Smart Inverter Profile “CSIP”), and introduced the SunSpec Public Key Infrastructure (PKI). To date, we have issued 76 CSIP Certifications, the IEEE 2030.5-2023 standard is nearly final, work on CSIP 3.0 is beginning, PKI upgrades are underway, and IEEE 1547-2018 is almost universally adopted across the U.S. With all this progress, questions remain about how utilities and grid operators will deploy network-capable DER systems.
Important Updates Coming in June
In the next few weeks, California IOUs will likely release advice letters on the IEEE 2030.5 rollout and need for a CSIP 3.0 update to reflect publication of the IEEE 2030.5-2023 standard, followed by a CPUC comment period for industry feedback. A critical question on the horizon is “How can CSIP 3.0 be updated quickly?” without causing deployment delays. SunSpec is ready to take the lead, ensuring that our push for standardization continues to support industry growth. On June 19 at 10 AM, SunSpec will host a webinar to discuss CSIP 3.0. Be on the lookout for an invitation to register.
On the SunSpec Modbus for IEEE 1547 front, the Alliance and our peers at EPRI continue to make strides to improve communication protocol- and functional interoperability. Please join us at our upcoming IEEE 1547 webinar on June 4 at 9 AM Pacific to learn about the latest improvements. As we have stated many times, IEEE 1547 communication interfaces that are tested and certified save product development teams many man months in testing effort per development cycle and accelerates time to market.
SunSpec Annual Meeting: Going Back To La Jolla/San Diego!
One of the best SunSpec Annual meetings ever was our 10th anniversary event in lovely La Jolla, California. The atmosphere (and weather) was fantastic, the content was enriching, and the camaraderie enjoyed with fellow members was unparalleled. Seeking to improve on that experience, we are happy to invite you to join us at the iconic Grande Colonial Hotel on December 3-5, 2024. Registration and Early Bird pricing will be available soon.
