It was another mostly bullish week for gas and power contracts in GB this week, continuing trends observed across much of July. Day-ahead gas rose 13.3% to 102.00p/th, following periods of undersupply during the week and buoyed by prolonged maintenance works across the NCS reducing flows into GB from Norway. Day-ahead gas prices reached a three-year high on 29 July, at 103.75p/th. Day-ahead power lifted 5.2% to £101/MWh, taking direction from notable gains made in near-term gas markets and low wind output during the week. August 21 gas was up 14.9% at 102.20p/th, and September 21 gas increased 12.7% to 102.20p/th. Most seasonal gas contracts boosted this week, up by 5.0% on average, with winter 21 and summer 22 gas increasing 8.1% and 7.4%, to 101.20p/th and 60.15p/th respectively. All seasonal power contracts traded higher this week, up on average by 3.9%. Winter 21 and summer 22 power went up 6.3% and 5.1% respectively, rising to £100.95/MWh and £66.20/MWh. Brent crude oil rebounded this week, rising from losses seen in the week prior. Subsequently, prices were 4.8% higher at $74.93/bl. This week was the first time in almost a month where carbon prices rose; following three consecutive weeks of decline the EU ETS reversed this trend, up 2.7% to €53.38/t. The UK ETS shared this bullish sentiment, also up marginally to £43.40/t.
