Other Industry Participants
In the last 25 or so years, additional wholesale industry participants that specialize
primarily in one function have come on the scene. For example, independent power
producers (IPPs) are for-profit entities that develop and operate electric generation
projects, and sell the output to utilities and large end-users. This industry segment was
jump-started by provisions in the Public Utility Regulatory Policies Act of 1978
(PURPA), a federal statute that required traditional utilities in certain situations to buy
power from IPP generation projects. Their national trade association is the Electric
Power Supply Association (EPSA). Some marketers do not own generation, transmission
or distribution facilities, but buy and resell electric power and transmission/
distribution services to both utilities and end-users. To make things even more complicated,
many of these major IPPs and marketers are separate subsidiaries in the same
corporate family as one or more traditional IOUs. Financial services companies (for
example, investment banks and hedge funds) have also gotten into the act, buying
financially distressed generation assets from IPPs and buying and selling both electric
power and financial instruments related to electric power (futures, hedges, virtual
power transactions, congestion rights, etc.).
