UK Energy Market Report – 15 June 2026

A possible US-Iran deal pulls oil lower and unwinds the Middle East risk premium, but UK gas holds firm on the Norwegian Troll outage.

The week opens with two forces pulling in opposite directions. A possible US-Iran agreement to reopen the Strait of Hormuz has taken the heat out of oil, dragging Brent down around 3 percent towards 84 dollars a barrel.

Yet UK gas has held its ground, kept tight by the compressor failure at Norway’s Troll field that continues to limit flows into Britain.

For business energy buyers, that split matters. The geopolitical fear that lifted the whole curve in late spring is fading, but the physical supply story on this side of the North Sea has not gone away.

Gas Market

NBP day-ahead opened around 119.5 pence per therm, easing roughly 3 percent on the day as the Middle East risk premium came out of the market. On the week it is broadly flat, a sign that the Troll outage is offsetting the softer geopolitical tone.

The Troll compressor failure is still cutting upstream Norwegian capacity by about 30 million cubic metres a day, trimming imports into Britain by roughly 10 mcm a day. With UK stocks low for the time of year, that lost supply has to be replaced by LNG or by pulling harder on the interconnectors.

The front month, July, sits near 117 pence per therm, with Winter 26 around 121.5. The long-dated picture stays much softer, with Cal 28 closer to 88 pence, so the curve remains in backwardation. The market is pricing tightness now and comfort later.

Weather is doing little to help either way. Forecasts are close to seasonal norms, so there is no strong heating or cooling demand to swing the balance, which leaves the supply side firmly in charge of near-term direction.

Electricity Market

UK day-ahead baseload power eased to about 72 pounds per megawatt hour, down close to 7 percent on the day. Stronger wind output is the main driver, with generation forecast to build through midweek and cover a larger share of demand.

That extra renewable supply takes pressure off gas-fired plant, so the day-ahead has fallen faster than the gas curve. CCGT output remains the swing fuel, filling the gaps when wind drops away.

Interconnector flows and available nuclear capacity will shape how far power can fall this week. When wind is strong and imports are flowing, the system can lean less on expensive gas plant, and that is what is pulling the prompt lower today.

Forward power tells the same backwardation story as gas. July sits near 101 pounds, Winter 26 around 104, while the longer-dated Cal 28 trades closer to 80 pounds. Buyers looking further out are still being offered materially lower prices than the prompt.

Oil, Carbon and Global Commodities

Oil is the headline mover. Brent has dropped around 3 percent to near 84.50 dollars a barrel after Iran’s deputy foreign minister confirmed a deal had been reached, with the text due to be signed in Switzerland. WTI followed lower.

The Strait of Hormuz carries close to a fifth of seaborne oil, so any genuine de-escalation removes a large chunk of risk premium from the market. Carbon was steady, with the December EUA contract holding near 77 euros a tonne. European TTF gas also softened, settling around 47 euros per megawatt hour.

Storage and Supply Outlook

European gas storage sits around 45 percent full and is injecting, though it remains below where it was this time last year. That below-normal starting point is one reason the market is still sensitive to any supply loss during the summer build.

UK stocks are low, which leaves Britain more exposed to outages like Troll and more reliant on competing for LNG cargoes against Asian buyers. For now LNG arrivals into northwest Europe have been healthy, which has helped cap the upside.

The risk to watch is how quickly Troll capacity returns. If the outage drags on into the injection season, Europe has to work harder to refill stores, and that competition tends to keep a floor under near-term prices.

What This Means for Your Business

The near-term and long-dated split is the story to take away. Prompt and winter prices are being held up by a genuine supply problem, while contracts two and three years out are noticeably cheaper.

If your renewal falls in the next few months, the softer geopolitical tone is helpful, but do not assume the Troll-driven tightness clears quickly. For buyers with flexibility, the backwardated curve is an opportunity to lock longer-dated volume at a discount to the front of the market.

Every business has a different risk profile, and timing a fix around a fast-moving supply story is rarely simple. To talk through your options, speak to one of our energy consultants today.
