Purpose
We have embarked on a multi-phased engagement with industry stakeholders to advance work on the new market design. It is comprised of a series of information sessions, written feedback cycles, and design sessions (sprints) to dive deeper into each workstream to explore and consider stakeholder perspectives and inputs prior to beginning the rules consultation process.
We will strive to ensure overall alignment with the stated REM objectives of:
- Reliability
- Affordability
- Decarbonization by 2050
- Reasonable implementation
