It isn't clear that the Order 1000 cost allocation principles are either internally consistent or lead to fair, long-run efficient outcomes. For example, within some RTOs, NITS rates vary by an order of magnitude across transmission providers. It is reasonably arguable the marginal cost of transmission capacity is relatively the same in most regions. There may be differences in the cost of land acquisition, etc., and some terrain may be more expensive to erect towers on. Still, I wonder if that difference is anywhere near as significant as the differences in NITS service charges across transmission provider footprints. For many of these transmission providers, these cost differences are only reflective of high costs in particular areas of the transmission system, not their system as a whole. For example, PSE&G's rates are more reflective of the high costs in and around Newark than they are reflective of the costs of constructing transmission in, say, the southern part of their service territory. However, the NITS rates basically socialize the costs across their entire footprint.

These rate differences have implications for the siting of future resources. Location is not material, with the exception of congestion, if all a resource is doing is bidding into the day-ahead market. Most renewable resource financing, however, requires some form of a contract with a party for the output. That may include the costs of acquiring NITS services.

The current version of transmission pricing mixes marginal costs in the short-run, i.e., LMPs, and embedded cost pricing in the long-run, that is, the NITS service, and does the latter pricing geographically. It may be a bad analogy, but NITS service is like a highway system that everyone participates in, while point-to-point is like a toll road. We don't differentiate how we provide or pay for the highway system across users except on the basis of potential wear and tear, trucks vs. cars, for example, or vehicle weight, and certainly not geographically. However, we do for the transmission system, even though it is equally a kind of public good.
