I seem to think that most pylons that are updated, now have fibre optic put on one of their lines as standard. You get no extra unless they activate them. No idea what rate to charge, but if they ever did get to use them, then that would be a case for all the farmers with the same line crossing the land to employ a single agent and do a bit of collective bargaining.
We have a good relationship with the power people. Two of the lines that go through us have been updated, and both times they gave us lots of input which led to one of the lines being resited along a hedge, and the other being spaced differently to allow for easier spraying. Pylons pay very well, especially as they would rather a one off cash payment, which for the area they occupy is good money. National Grid also relayed an entire 750m stretch of farm track at their cost, and did a proper job with all the kit, liners and decent grades of stone.
Cant be too negative - I am hoping they will put me a discounted new three phase supply in soon.
