Carbon intensity update for 9th Oct 25

Understanding the carbon intensity of electricity is vital for anyone looking to reduce their environmental footprint. At Jaxi, we provide daily updates to help you make informed decisions about when to use your appliances. Here’s the carbon intensity breakdown for the UK on October 9, 2025.

Midnight to Morning: The day started with relatively stable carbon intensity levels in the moderate range. Between 00:00 and 08:00, values fluctuated between 121 and 132 gCO₂/kWh, suggesting a good window for running appliances such as dishwashers, washing machines, or overnight charging for electric vehicles.

Afternoon to Early Evening Peaks: As demand increased during the day, especially during peak hours, carbon intensity saw a significant rise. From 17:00 to 17:30, levels surged to a high of 218 gCO₂/kWh, entering the high carbon intensity index. This increase is often triggered when electricity providers turn to fossil fuel sources like coal or gas to meet high demand after renewable resources are exhausted.

Evening Decline: After peaking, the carbon intensity gradually fell. By 20:00, it had returned to a moderate level of 176 gCO₂/kWh, and by 22:30, it further dropped to 136 gCO₂/kWh. This pattern suggests that late evening is generally a better time to schedule energy-intensive activities when aiming to minimise your carbon impact.

Why Real-Time Data Matters: One key insight from today’s data is that actual carbon intensity exceeded forecasts during peak periods. This reinforces the importance of monitoring real-time carbon metrics rather than relying solely on projections. Such awareness helps you plan energy usage more effectively and contribute to lowering overall demand during dirty energy spikes.

How Jaxi Helps: With Jaxi, you can stay ahead of carbon trends and choose the most eco-friendly times to use electricity. By aligning your energy usage with periods of low carbon intensity, you not only save on emissions but also support the UK’s transition to a greener grid.
