5.5 cents per kwh -
I wish! Hydro is good for being cheap, you guys have it great.
A quick check of my last bill tells me I paid about 9 cents per kwh - and that's not including the "transmission charge", the "transmission account deferral rider" (I am not making this up), the "distribution charge", the "local access fee" and the "balancing pool allocation", oh wait, that last one looks like a small credit, never mind.
So yeah, I dunno, $20 per month doesn't sound so bad on its own, but in some cases it may be more than that. But assuming that it IS $20 per month, that's $240 per year. Suddenly those Tunzes don't look so bad to me, and then there's the advantages that Ruth listed (ie easy to change around if needed and so on).
I guess I shouldn't knock the CL idea totally though. They do have their advantages, espescially with the Calfo manifold idea.
