According to  http://energynumbers.info/gbgrid
biomass production is 2.4G -never seen it this high ! any reasons why ??

Just Drax burning American trees rather than coal. From what I understand Drax's biomass output from 3 of its converted coal plants is covered via contract for difference (CFD) subsidies, so from their point of view it makes sense to run them as much as possible. These 3 and the most recently converted plant could allow up to 2.6GW of biomass-based output.

Yes , maybe .......
I know several local biomass producers -big diary or chicken farms  -where does their output get recorded?

It depends. Generally they won't be monitored on the transmission grid, so you won't see them on my  http://energynumbers.info/gbgrid

You might see them in electralink data. But not many of us have access to that. I don't.

It's easy to check real-time as Draw puts their total output up on their website https://www.drax.com/

So if they have output while no coal burning is being recorded at somewhere like gridwatch you are looking at biomass burning.

At the time of writing Drax is saying that they are outputting 1.941 GW, while gridwatch is showing no coal output and a total of 2.38GW of Biomass.

The answer is Lynemouth power station in Northumberland. Aprox 400MW sent out.
It was built to power the neighbouring Alcan aluminium plant (closed down). The plant has been converted to biomass recently.
When it ran on coal from the nearby Ellington colliery, it had the highest thermal efficiency of any coal plant on the uk!
