Carbon intensity update for 6th Sep 25

Stay informed and make smarter energy decisions with Jaxi’s daily carbon intensity updates. On 6th September 2025, the UK experienced fluctuations in electricity carbon intensity levels, reflecting shifts in energy demand and supply. Knowing when the grid is greener can help you reduce your environmental impact by timing your energy use wisely.

UK Carbon Intensity Summary for 6th September 2025

Carbon intensity measures how much carbon dioxide (CO₂) is emitted per kilowatt-hour (kWh) of electricity generated. A lower number means cleaner, more renewable energy is powering your home or business. Here’s a breakdown of today’s data to help you plan your energy usage more sustainably.

🕒 Timeframe Breakdown

• Overnight (12:00 AM – 5:30 AM): The day began at a moderate intensity of 128 gCO₂/kWh, gradually dropping to 94 gCO₂/kWh by early morning. This period was cleaner than average but not the greenest window.
• Morning (6:00 AM – 11:30 AM): Excellent conditions for low-carbon energy use, with values reaching as low as 61 gCO₂/kWh. Ideal for running dishwashers, washing machines, or charging electric vehicles.
• Afternoon (12:00 PM – 5:30 PM): Consistently low intensity throughout the afternoon, ranging between 59–50 gCO₂/kWh. A perfect time for heavy energy use while keeping emissions minimal.
• Evening (6:00 PM – 11:00 PM): Low carbon intensity persisted into the evening. Despite minor fluctuations, including a brief peak at 64 gCO₂/kWh around 10:00 PM, this was still a relatively green time to use electricity.

📉 Today’s Key Figures

• Lowest Carbon Intensity: 49 gCO₂/kWh between 8:00 PM and 8:30 PM.
• Highest Carbon Intensity: 145 gCO₂/kWh just after midnight.

Why Carbon Intensity Matters

When demand is high and renewable sources are exhausted, additional electricity is generated by fossil-fuel-based power stations, such as coal or gas plants. This leads to higher carbon emissions. By aligning your energy-intensive activities with periods of low carbon intensity, you help reduce strain on the grid and cut down on the UK’s overall carbon footprint.
