NAESB Ratifies Standard for Green Button
On 8 April, the North American Energy Standards Board (NAESB), a member of the Green Button Alliance, ratified the latest revision of the NAESB Energy Services Provider Interface (ESPI) Retail Energy Quadrant Book 21 (REQ.21) standard, commonly known as the Green Button standard. Updates and enhancements to the standard were submitted to NAESB by the OpenADE Task Force, hosted by the Green Button Alliance, which included:
- Replaced OAuth 1.0 with OAuth 2.0 for “Confidential Clients”
- Updated security requirements to TLS 1.2 as a minimum
- Revised the Energy Usage Information (EUI) data structure and definitions
- Created the Retail Customer (PII) data structure and definitions
- Deprecated original Use Cases that do not meet OAuth 2.0 data security requirements
- Added Use Case for Download My Data (DMD)
- Simplified Use Case 2: “Customer Authorization process”
- Documented Standard ESPI Application Program Interface (API) formats
The current standard is now available for purchase from NAESB for $250.00 USD as the Final Action R13001 – Request for Corrections and Enhancements to the NAESB REQ.21 Energy Services Provider Interface (ESPI).
