Solar - notification of new coefficient

Has anyone who sells electricity from solar to EDF had a letter regarding a new coefficent? I cannot make out what the new pricing is so wondered if anyone else has.

I’ve been selling for 4 years now. but haven’t had one. I’ll look out for it and let you know if I get one.

Thank you. We have been selling for about 16 years so we may be on different contracts.
I don’t understand the technical bit I am reading as the figure stated is a lot higher than last year or a lot lower, so a bit baffling. I don’t have to do anything so it may just be a matter of waiting for me to submit my next readings in March.
