Real-time pricing cleared above day-ahead on average, with DA LMP at about $52.82/MWh versus RT LMP at about $63.27/MWh, producing an average DART of -$10.45/MWh. The strongest real-time pricing was concentrated in HE18-20 as net load stayed elevated while solar output rolled off and wind output remained comparatively low.
