What counts in the renewable share
Energy Mix treats renewable share as the share of measured generation coming from renewable sources such as wind, solar and hydro. It is a practical live-grid metric rather than a billing-grade certificate measure.
The renewable share can change quickly as weather-driven generation moves and demand rises or falls.
Recent renewable context
The latest weekly report says renewables averaged 40.5%, with 52.8% on Sunday 27 September.
Current measured 7-day high: 52.8% average renewable share on Sunday 27 September, based on the available historical generation feed.
FAQs
Does renewable share include nuclear?
No. Nuclear is low-carbon, but it is not counted as renewable in these share calculations.
Is high renewable share always low carbon?
It is usually a strong low-carbon signal, but carbon intensity also depends on gas, imports, demand and other generation.
