Software Product Vision

Our vision for this project is to create a greenfield attribute tracking software that is accurate, effortless, and empowering — a tool that saves time, reduces stress, builds trust, and provides users with a seamless experience.

Software Launch Date Update

Following a collaborative review among WREGIS users, our team at WECC, and our development partner Atomic Object, we are announcing an updated launch date for the new WREGIS software: February 17, 2027.

This date reflects the shared priorities and feedback collected through the recent user survey regarding year-end compliance deadlines and scheduling needs and our joint assessment with Atomic Object of the development timeline to support a successful rollout of the software’s Phase 1 features and required system functionality.

We will continue to keep stakeholders informed as we develop and prepare for the new WREGIS software platform.

WREGIS Training Tip: Shared Meter Groups

Shared Meter Groups, (also called Aggregated Meter Groups), are a specialized generator registration variation that links separate, stand-alone generators together with a single meter. This is common when large facilities go live in phases, resulting in generators with different Commenced Operation Dates that all feed into one meter. Stand-alone generators, with separate revenue grade metering attached to all units, should not be grouped this way.

Generation data is reported to WREGIS as one value for all generators within the Shared Meter Group. Organizations can allocate that generation to individual generators within the group as determined by contract or performance within the 14-day holding period, or the system will perform a prorata nameplate calculation at the time of issuance to distribute the certificates. If you have questions about this type of registration, reach out to wregishelp@wecc.org.

Western Renewable Energy Generation Information System (WREGIS) is an independent, web-based tracking system for renewable energy certificates (REC), predominantly in the West. WREGIS is a WECC non-statutory program.
