Finally someone did follow

[ucodegen]

Finally someone did follow through and check the numbers.. and yes, I found those numbers around Noon.. Much better than arguing semantics..

here, you want numbers, you got numbers:

~$4 surcharge per 150 kwh

7.649 c /kwh/mo

Though this calculation is incorrect.. you need to divide 15917kWh average usage by 150kWh block size..

4 * 1200/150 = $32 green surcharge/mo

should be
$4 * 15917/150 = $424.45
($4 per block of 150kWh, 15917kWh used avg per month, 15917/150 green power blocks).

which seriously changes the rest of your figures..

What is interesting is that taking Gores cost and dividing by kWh served, you get very very close to a non-green rate charge!
your numbers of 1200/15917 = $0.0759

The green rate charge should be adding $4/150kWh or $0.02666 per kWh to the standard residential rate of $0.07649(non-green TVA), which means we should be seeing a rate of $0.103156/kWh (close to where I guesstimated it would be).

TVA does both Green(Green Switch) and non-Green energy.
