SunSpec Alliance
@sunspecalliance.bsky.social
A global trade alliance of distributed energy resources (DER) industry participants, together creating information standards to enable “plug & play” system interoperability, grid interconnection, and secure data communications. Find us at sunspec.org!
"We think Critical Loop's secret weapon is to embrace some of these standards [IEEE 2030.5 and UL 3141]"

This video discusses exactly what the SunSpec ecosystem is all about: interoperability, safety, and speed to market. Welcome to SunSpec, Critical Loop!

California has the potential to almost double its clean energy generation by tapping into surplus interconnection capacity. No new transmission lines required.
At SunSpec, we build the digital framework to make integrations like this scalable, secure, and interoperable. #energysky
California could nearly double generation capacity using surplus interconnection: UC Berkeley report
The authors say about 16 GW of thermal capacity — dominated by gas — is operating below a 15% capacity factor, making it ripe for adding solar, wind or storage.

A reflection on Intersolar Europe/the smarter E:
🌐 Standards Divergence Is Holding Us Back
Across Europe and beyond, fragmented standards and self-declarations are creating serious pain points. There is a clear need for a harmonized framework. This is where SunSpec brings unique value! #energysky
