UK Energy Market Report — 10 July 2026

What we’re watching today

• Carbon intensity forecast at 236 gCO2/kWh (very high)
• Gas generation at 55.9%, with 16.7% from imports
• Sizewell B extended to 2055; Lynemouth Power Station secures CFD
• Global oil markets show U.S. dominance and Middle East tensions

Headlines and what they mean

Sizewell B power plant given lifetime extension to 2055

The extension of Sizewell B’s operational life to 2055 confirms the government’s commitment to maintaining nuclear capacity as a stable, low-carbon baseload source. This decision supports long-term energy security and aligns with the UK’s net zero targets, particularly as renewable intermittency increases. The move signals confidence in nuclear’s role in the energy mix beyond 2030 source.

Lynemouth Power Station: signature of low-carbon dispatchable Contract for Difference

Lynemouth’s CFD signing marks a strategic shift toward securing flexible, low-carbon generation. The project, likely involving carbon capture or hydrogen co-firing, is designed to provide dispatchable power during peak demand or low renewable output. This signals growing government support for hybrid and retrofit technologies to bridge the gap between renewables and grid stability source.

Government approves UK’s second largest solar farm

The approval of One Earth Solar Farm underscores continued momentum in large-scale solar deployment. With over 1 GW of capacity expected, this project will contribute to the UK’s renewable expansion targets and reduce reliance on gas peaking plants. The decision reflects strong policy backing for solar, particularly in low-density, land-optimised zones source.

Draft strategic policy guidance for electricity networks growth

The draft guidance outlines a framework for accelerating grid expansion to accommodate new generation and demand-side flexibility. It signals a move toward proactive network planning, reducing bottlenecks and enabling faster integration of renewables and storage. This is critical as the UK transitions to a more distributed and dynamic grid source.

Longer Duration Energy Storage (LoDES) Demonstration Programme: successful projects

The selection of LoDES projects highlights progress in deploying storage technologies beyond lithium-ion, including thermal and hydrogen-based systems. These projects aim to provide multi-day or seasonal storage, crucial for managing winter peaks and renewable variability. The success of these pilots may inform future funding and regulatory support for long-duration solutions source.

Geopolitics and global markets

U.S. crude production surpassed all other nations in 2025, reinforcing its position as a global oil leader source. U.S. crude and product exports reached record levels in April, increasing global supply flexibility. Meanwhile, renewed Iran conflict and Middle East tensions are prompting market speculation, though the Fed anticipates cooling oil prices despite escalation source. The Strait of Malacca faces potential shipping fee disruptions, which could affect LNG and crude flows to Asia, indirectly influencing European prices. Indonesia’s receipt of its first Russian crude shipment under a new supply deal signals shifting trade patterns, with implications for global crude flows source. BP’s potential exit from the North Sea under new leadership may affect UK offshore investment and energy security, particularly if asset divestment accelerates source.

The view from the trade desk

Grid carbon intensity remains at a very high forecast of 236 gCO2/kWh, driven by gas (55.9%) and imports (16.7%). Wind and solar output are low at 5.8% and 1.7% respectively, indicating a reliance on dispatchable generation. This context suggests that energy buyers should prioritise flexibility and carbon-aware procurement, especially during peak demand windows. The current mix supports a strong case for using the Yolk portal to monitor real-time carbon and price signals, particularly for firms with Scope 3 targets.

What to do this week

• Review procurement strategy for Q3, given elevated carbon intensity and gas dependency; consider increasing flex load allocation
• Assess potential for signing a CFD-linked or corporate PPA with a project like Lynemouth or One Earth Solar Farm
• Engage with NESO’s draft network guidance to understand future grid access risks and timing
• Monitor LNG and oil market developments for potential impact on wholesale gas prices
• Evaluate storage and demand response options to reduce exposure to high-intensity periods

Bottom line

The UK energy market remains anchored in gas and imports, with carbon intensity forecast at 236 gCO2/kWh. Policy momentum is strong, with Sizewell B’s extension and new solar approvals reinforcing long-term decarbonisation. However, grid volatility persists. Energy buyers should prioritise flexibility, real-time carbon monitoring, and strategic engagement with emerging infrastructure and storage projects. The global oil and LNG landscape remains dynamic, with U.S. dominance and Middle East tensions influencing price and supply stability.
