OpenADR Hackathon | September 30 & October 1

OpenADR Hackathon – Test & Interoperate
Join peers to prove interoperability and validate your implementation in practice. In focused test sessions you’ll check compliance with the OpenADR 3 specification and confirm your product works seamlessly with others. Built on modern web-service principles, OpenADR 3 is simpler than legacy message-exchange formats, making energy management easier to build, integrate and scale.

Join us to compare approaches, learn from peers and shape interoperable demand response.

What’s in it for you?

Faster integrations: get hands-on with OpenADR 3’s modern, developer-friendly API style (REST/JSON), so your team spends less time on plumbing and more time on features
Have questions about OpenADR 3? The OpenADR Alliance will be present for two days of Hackathon where you’ll have a chance to learn and get help implementing.
Network that matters: meet other developers who are active in the fields of utilities, CPOs, aggregators, OEMs, EMS/DERMS vendors, researchers — the people you’ll integrate with next quarter.

Don’t miss it when you are a Protocol Engineer, System Architect, Program Owner working on demand response, and if you are working in EV smart charging and grid interoperability!
