Carbon intensity update for 7th Sep 25

UK Carbon Intensity Update for September 7, 2025

At Jaxi, we believe in empowering our users with real-time insights to make smarter, greener energy decisions. Understanding the carbon intensity of electricity can help you plan when to use high-energy appliances and reduce your impact on the environment.

On September 7th, 2025, the UK maintained low carbon intensity levels throughout the day—a promising sign of ongoing progress toward cleaner energy usage.

🕛 Midnight to 6 AM: Clean and Quiet Start

Between 12 AM and 6 AM, the carbon intensity ranged between 63 and 71 gCO₂/kWh. Forecasts closely matched actual readings, highlighting the increasing accuracy of predictive models. This period is ideal for running energy-intensive appliances like dishwashers or EV chargers if you want to minimize environmental impact.

🌅 Morning Hours: Continued Low Emissions

From 6 AM to 12 PM, carbon intensity remained low, despite a minor peak of 69 gCO₂/kWh around 6:30 AM. The steady performance during high-demand hours underscores the role of renewable energy in meeting national needs.

🌤️ Afternoon Performance: Sustainability in Action

Between 12 PM and 6 PM, the carbon intensity stayed consistent and low, with the highest value recorded at 72 gCO₂/kWh just before 5:30 PM. These favorable levels reflect the successful integration of solar and wind power into the UK grid during daylight hours.

🌙 Evening Update: Slight Increase, Still Low

During the evening peak (6 PM – 11 PM), carbon intensity experienced a slight rise, reaching 86 gCO₂/kWh at around 7 PM. By 11 PM, however, it decreased again to 63 gCO₂/kWh. Even during higher demand periods, the grid remained environmentally friendly.

🌍 What This Means for You

This consistent low intensity throughout the day demonstrates the UK’s growing reliance on clean energy sources and decreased dependence on fossil fuels like coal. High energy demand sometimes forces generators to use more carbon-intensive methods, but thanks to evolving technology and better planning, days like this are becoming more common.

By aligning your energy consumption with periods of low carbon intensity, you contribute to reducing emissions and supporting a sustainable energy future. Jaxi is here to keep you informed with daily updates, helping you make eco-smart decisions effortlessly.
