Carbon intensity update for 5th Oct 25

Stay informed with Jaxi’s daily carbon intensity updates to help you make smarter, greener energy choices. On October 5, 2025, the UK’s electricity grid demonstrated strong performance in maintaining low carbon emissions for most of the day. These insights are especially important for those looking to reduce their carbon footprint by timing the use of appliances when the grid is cleaner.

Why Does Carbon Intensity Matter?
Carbon intensity refers to the amount of carbon dioxide (CO2) emitted per kilowatt-hour (kWh) of electricity generated. When demand is high and renewable sources like wind and solar are insufficient, fossil fuel generators—such as coal or gas—may be used to meet demand. This results in higher emissions. Monitoring carbon intensity helps you plan your energy usage when electricity is coming from cleaner sources.

October 5th Carbon Intensity Breakdown:

• 11:00 PM – 6:00 AM: The night started strong with a consistent low carbon intensity, averaging in the mid-50s gCO2/kWh.
• 6:00 AM – 9:00 AM: A slight increase occurred during this typical morning demand peak, reaching up to 67 gCO2/kWh before stabilising.
• 9:00 AM – 2:00 PM: Emissions declined steadily, with values ranging between 49 and 53 gCO2/kWh — an ideal time for running dishwashers, washing machines, and charging devices.
• 2:00 PM – 4:30 PM: A minor rise was observed, but carbon intensity remained under control and stayed relatively low.
• 4:30 PM – 6:30 PM: The day’s peak occurred during the early evening, hitting an actual high of 89 gCO2/kWh — a time to consider limiting heavy appliance use if possible.
• Evening Hours: As we moved into the later hours, emissions dropped back down, closing the day on a cleaner note.

What This Means for You
The availability of low-carbon electricity throughout most of the day means there were plenty of opportunities to power your home sustainably. By aligning your energy consumption with times of lower carbon intensity, you’re not only saving on potential costs but also contributing to a cleaner grid and lower national emissions.

At Jaxi, we provide real-time carbon intensity updates so you can make decisions that support a more sustainable future. Every small change adds up. Whether it’s shifting your laundry run to midday or delaying your EV charge until late evening, your actions matter.
