Forward-looking module. SAWEM has not commenced trading — the launch has moved to Q3 2026 and several market rules remain unresolved. Positions, prices and settlement shown here are modelled against the published market design (NTCSA as market operator, Balance Responsible Party framework, bilateral contracts) to demonstrate readiness, not live market participation.
