Electricity Tariffs
Deregulation of electricity markets is determined at the State level in the US. Currently 15 states (30%) provide for at least some, or all, customer classes to purchase power on a deregulated basis. However, because this group includes the relatively populous states of New York, Texas, and Illinois the percentage of the market which is deregulated approaches 35%. Under...
The Challenges of Index Pricing
Wholesale prices as reported by the 7 US ISOs (Independent System Operators) come in two flavors: Next-Day, in which power is priced for delivery for the following day with each of the 24-hourly prices set independently. Real-Time, in which the price for power is (usually) set after the 5 minute to 1 hour settlement period has been realized. In both cases the price for...
