Carbon intensity update for 19th Oct 25

Stay informed with Jaxi’s daily carbon intensity updates to help you make smarter energy decisions. By keeping track of electricity grid demand and the associated carbon intensity, you can optimise when to run energy-hungry appliances and contribute to a cleaner, greener UK.

Here’s your detailed carbon intensity report for October 19, 2025:

• Late Night & Early Morning (Oct 18, 11:00 PM – Oct 19, 8:00 AM): Carbon intensity levels remained low between 55 and 63 gCO₂/kWh. Renewable energy sources such as wind and solar contributed significantly during these hours — an ideal time to run dishwashers, washing machines, or charge electric vehicles.
• Morning to Afternoon (8:00 AM – 4:00 PM): A slight increase was observed with peak carbon intensity reaching 73 gCO₂/kWh around midday. Although still low, this moderate rise suggests a gradual shift in energy supply sources as demand increases.
• Afternoon to Evening (4:00 PM – 7:00 PM): A more noticeable rise in carbon intensity occurred during peak energy demand. Levels reached up to 89 gCO₂/kWh by 6:00 PM, indicating the likely use of fossil fuel-based generators like coal and gas to meet the high load. If possible, avoid using high-energy appliances during this timeframe to reduce carbon emissions.
• Evening to Late Night (7:00 PM – 11:00 PM): Carbon intensity began to decrease again, ending the day at 71 gCO₂/kWh. As demand tapers off, the grid shifts back to cleaner sources, making it another suitable window for energy use.

Overall, October 19th showcased a low daily carbon intensity trend across the UK. This is a positive indicator of the growing contribution from renewable energy to our national grid. However, spikes during peak hours remind us that fossil fuels are still occasionally required, particularly during high-demand periods.

At Jaxi, our goal is to empower households and businesses with real-time data so you can plan your energy usage wisely. By using appliances during periods of lower carbon intensity, you’re not just saving money—you’re actively supporting the shift to a sustainable energy future.
