PowerCast: September Power Market Recap - volatility, wind, BM shifts
Monthly market update from EDF Wholesale Market Services. Rachel is joined by analysts Robbie Auld and Bhanu Duggal to unpack September’s UK power markets: stronger wind, deeper day-ahead dips, and what it meant for batteries.
What we cover
Prices and volatility: lower averages on strong wind, deeper negative periods, and wider wholesale spreads for batteries.
BM activity: record daily battery offers, regional patterns, and interconnector outages shaping dispatch.
Rule changes: how the ABSVD treatment shift and non-BMU access to Quick Reserve from 3 September change strategies.
Ancillary services: knock-on effects across DR, DC, and DM as competition and pricing rebalance.
Battery revenues: highlights from our Battery League tables and where value showed up.
Winter outlook: NESO’s latest view on margins and what a windy winter could mean for spreads.
