Grid-Fed Electricity and Tax.

Yes, like throwing a fish by-catch back into the sea, it would be a criminal waste

I don't know for certain but I assume that anyone "intending" to produce a lot of electricity for export to the grid would be likely to setup a company as an umbrella to such an operation which would have a whole different set of tax regulations applied - capital allowances, depreciation write-offs, corporation tax, etc.  Therefore anyone who had not setup such a company was not "intending" to export much.
