April Energy Market Insights: Solar Surges, Battery Revenues & Grid Balancing Challenges

In this episode of Powercast, David Edmonds is joined by EDF analysts Curtis Higgins and Robbie Auld to explore key developments in the UK energy markets during April. Together, they unpack how high solar generation, subdued wind output, and falling gas prices shaped wholesale prices, balancing mechanism activity, and battery revenue streams. The team discusses the impact of record-breaking solar PV, the nuanced role of interconnectors with Europe, and how evolving ancillary services like dynamic containment and regulation are affecting operational strategies. They also examine the introduction of the new Response Energy Volume (REV) rules and the implications for one-hour versus two-hour battery assets. Looking ahead, the episode considers potential market dynamics for May and June — from weather-driven demand shifts to National Grid ESO’s ambition for fossil-free operation windows. With expert insights and real-time data analysis, this is essential listening for anyone active in or observing the GB electricity markets.
