Benefit of Customer Load Shift
Benefit of Customer Load Shift
(OP)
The utility I work for just completed a Smart Grid Business Case. One of the identified benefits of the Smart Grid is having customers shift usage from on to off peak periods.
For each KW of on peak demand shifted, consulant used a deferred T&D capital benefit of $685 / KW - Year based on a 2007 DOE Study on The Potential Benefits of Distributed Generation. This value sounds very high to meet based on the cost for substation and distribution capital projects I have been involved with to date.
How are other utilities quantifying the benefit of shifted KW peak?

That's above wholesale price, but less than retail for residential customers.
Could be reasonable, depending on who's counting.

Also consider that you have to count high in order to justify using tax-payer provided money for smart grid stuff.
RE: Benefit of Customer Load Shift
The crudely calculated cost benefit of shifting load should be something like A + B where:
A = Reduced generation cost due to reduced need for investment in peaking generation, lower cost generation
B = Reduced cost of building/maintaining smaller T&D system
[A] can be calculated with some degree of accuracy, but I suspect this number is fairly small.
[B] is a very subjective number. It's like asking how much more it costs to add a sweater to an old soft-sided suitcase. You know you can't keep adding clothes forever without buying a new or bigger suitcase, but there's no clear cost.
