PowerCastMarket Recap: November's Renewables Rise, Spreads Narrow and Winter Signals Emerge

This month we're joined by market analysts Curtis Higgins and Will Illesley to review how GB power markets performed in November, covering wholesale prices, the Balancing Mechanism and ancillary services. November was characterised by strong renewable generation and a generally stable system, which led to narrower market spreads and slightly lower battery revenues compared with October. A cold snap mid month increased demand and created short periods of price volatility, but prices eased later in the month as wind generation increased and reliance on gas reduced. The episode also highlights a notable milestone for wind, with Great Britain setting a new maximum wind generation record during November. The discussion includes a clear explainer on triads and why they matter for flexible assets, including how potential triad days influence optimisation strategies and spill over into frequency response and wholesale markets. The team also explores Balancing Mechanism trends, where volumes remained high but value softened, and how ongoing grid constraints, particularly in Scotland, continue to shape market outcomes.
