Carbon intensity update for 30th Oct 25

🌍🔋 UK Carbon Intensity Update for 30th October 2025 🔋🌍

At Jaxi, we’re committed to helping you make smarter energy choices by keeping you informed about real-time carbon intensity levels in the UK. By understanding when electricity is cleaner, you can plan your appliance use more efficiently and reduce your carbon footprint.

Here’s your detailed breakdown of today’s carbon intensity performance and what it means for you:

🌟 Low Carbon Intensity Periods (00:00 – 04:00 UTC & 19:00 – 23:59 UTC)

Great news! During the early morning hours and again in the evening, carbon intensity levels remained low — ranging between 68-101 gCO₂/kWh. These are ideal times to run high-energy appliances like washing machines, dishwashers, and electric vehicle chargers. Taking advantage of these low-carbon hours helps support cleaner electricity usage and reduces reliance on fossil fuels.

💡 Moderate Intensity Hours (04:00 – 19:00 UTC)

Between 4 AM and 7 PM, carbon intensity increased slightly, fluctuating between 101-171 gCO₂/kWh. This period typically sees higher demand as people wake up and go about their day. As renewable generation becomes stretched, backup generators powered by fossil fuels like coal or gas may be used—raising emissions. If possible, consider delaying non-essential energy use until low-intensity periods.

🔍 Forecast vs Actual Carbon Intensity Highlights

• Morning Adjustment: At 5:30–6:00 AM, actual intensity reached 138 gCO₂/kWh, slightly above the forecasted 107 gCO₂/kWh. This reflects unexpected demand or reduced renewable output.
• Evening Improvement: From 7 PM onwards, actual emissions dropped to 67 gCO₂/kWh, beating forecasts and signalling stronger performance from renewables than anticipated.

Understanding carbon intensity patterns allows you to make energy-efficient decisions that contribute to a greener grid. The more we synchronise our consumption with low-intensity periods, the less we rely on polluting backup sources like coal-fired power stations. Your choices matter—every kilowatt counts!

Stay connected with Jaxi for daily carbon intensity updates. Together, we can build a more sustainable future while saving money and reducing emissions—one smart energy decision at a time.
