PowerCast by EDF

In this episode, David Edmonds, Head of Pricing & Valuations, is joined by EDF analysts Curtis Higgins and Bhanu Duggal to explore the UK energy market dynamics for July. 

From changing generation patterns to shifting market dynamics, we explore the factors that shaped the month and what they could mean for the period ahead.

In this follow-up episode of the PowerCast podcast from EDF’s Wholesale Market Services team, host David is joined by Dan Wilkinson, EDF’s PPA Pricing and Valuation Lead, to explore the significant impact solar generation has had on Great Britain’s power prices during summer 2025.

The discussion dives into the concepts of solar cannibalisation, capture prices, and shaping costs, explaining how record levels of solar output have led to record low solar capture rates as low as 83% of the baseload price, compared with over 90% in previous years. This, combined with the continued influence of wind generation and growing European interconnection, has created new challenges for pricing and valuing intermittent renewables.

The conversation covers the drivers behind these trends, including unusually sunny weather, increased installed solar capacity, and imports of cheap solar power from continental Europe. The implications for both fixed-price and day-ahead PPAs are considered, highlighting the growing importance of understanding shaping risk and how it is reflected in offtake pricing.

Looking ahead, the episode explores how future capacity growth, particularly under the Clean Power 2030 targets could exacerbate these issues, but also how flexibility, demand growth, and on-site solar use may help mitigate them.

Whether you're an offtaker, generator, or simply interested in the changing shape of the GB power market, this episode offers a timely and in-depth analysis of one of the most pressing dynamics in renewables today.

In this episode of PowerCast, David from EDF’s Wholesale Market Services is joined by Rachel Murphy, Strategy Analyst, and Ed Bryan, Flexibility Product Design Lead, to explore the latest Future Energy Scenarios (FES) 2025 report from the National Energy System Operator (NESO).

The team discusses the four energy transition pathways - Holistic Transition, Consumer Engagement, Hydrogen Evolution, and Falling Short with a focus on key themes like flexibility, electrification, and infrastructure development. They unpack the report’s implications for energy demand, especially the rise of EVs, heat pumps, and data centres, and how EDF is positioned to support delivery at scale across the energy value chain. 

Listeners also learn about EDF’s PowerShift platform, its role in enabling demand-side flexibility, and the potential for Vehicle-to-Grid technology. The episode concludes with practical takeaways on how individuals and businesses can engage in the transition to net zero, from installing smart meters to investing in energy efficiency.

If you're in the energy sector, from consumers to battery developers, this deep dive into FES 2025 offers strategic insights on the UK’s path to a decarbonised future.

In this episode of the PowerCast EDF Wholesale Market Services podcast, David Edmonds, Head of Pricing & Valuations is joined by EDF analysts Curtis Higgins and Bhanu Duggal delve into the UK energy market dynamics for June.

A sharp rise in renewable generation, particularly wind and solar, led to increased volatility in wholesale prices, creating expanded market spreads and strong revenue opportunities for battery storage operators.

The month also saw record levels of bid activity in the Balancing Mechanism (BM), largely driven by transmission constraints at the B6 boundary in Scotland. Longer-duration battery assets outperformed due to their ability to capitalise on both wholesale price fluctuations and ancillary services.

As heat risks persist into July, the outlook remains positive for battery revenues, especially with potential for further price spikes.

In this special edition of PowerCast from EDF’s Wholesale Market Services team, we reflect on the recent escalation in the Iran–Israel conflict and its early impact on global energy markets.

Recorded yesterday (23 June) and already the markets have moved again, a reminder of just how volatile and fast-moving the situation is.

In this episode, David Edmonds is joined by Senior Curve Trader Stephen Carrington to discuss:

• Initial reactions in gas, oil, power, and carbon markets

🎙️ This episode offers insight without speculation, an informed look aiming to give listeners context on what these developments might mean for the energy sector in the UK.

In this episode of PowerCast, David Edmonds, Head of Pricing Evaluations at EDF’s Wholesale Market Services, is joined by Nikki Goulding and Kim Collins, two of EDF’s leading experts in PPA management. Together, they unpack the detailed work that goes on behind the scenes to get ready as the offtaker for large-scale renewable Power Purchase Agreements (PPAs). From contract handover to technical coordination and internal mobilisation, they walk through the critical steps that help bring projects like offshore wind farms to life. Learn how EDF navigates delays, manages complex stakeholder relationships, and ensures seamless delivery in a fast-evolving energy landscape. Whether you're a developer, generator, or just curious about the machinery behind Britain’s biggest renewable offtaker, this is an episode not to miss.

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.

In this episode of Powercast, host David Edmonds (Head of Pricing & Valuations, EDF Wholesale Market Services) sits down with Ed Bryan, Product-Design Lead for Flexibility, to demystify the brand-new role of the Virtual Trading Party (VTP) created by Balancing & Settlement Code modification P415. 

Together they unpack:

• what a VTP is, how it differs from a Virtual Lead Party, and why P415 finally lets independent aggregators trade customers’ flexibility directly in the wholesale market;

Whether you’re a supplier, flexibility provider or simply energy-curious, this conversation reveals how VTPs could shift consumption out of the evening peak, unlock new revenue for consumers and help Britain’s grid keep pace with renewables. Tune in, get the jargon decoded and see where demand-side innovation is heading next.

Our team — David Edmonds, Jared Morgan and Hugh Boyle — unpack the key outcomes of the recent T-4 & T-1 Capacity Auctions, what they mean for market participants, and how they could shape future strategy.

At EDF, we’ve been looking carefully at our PPAs and the costs and risks we price as an offtaker. As part of this activity, we asked LCP Delta to independently analyse the historical costs of shaping fixed-price solar PPAs and what a sustainable risk pricing approach might be.

As solar power continues to expand across the grid, the true cost of shaping fixed-price PPAs is becoming clearer — and more complex. While recent years may have offered a stroke of good fortune for offtakers, with aligned weather and market conditions keeping costs low, LCP Delta’s analysis shows this may not be a trend we can rely on in future.

What happens when the weather doesn’t cooperate — or when market prices move in unexpected ways? The report takes a hard look at these risks and what sustainable pricing really means for the long term.

Join David Edmonds, Head of Pricing & Valuations and Matt Flook, PPA and Renewable Certificates Senior Manager as they break down the key findings, explore what they mean for generators and offtakers alike, and hear EDF’s take on why responsible pricing is more important than ever in a volatile market.

Whether you're a generator, offtaker, an investor, or just energy-curious, you won’t want to miss this one.
