Competition brings transparency

More than 150 core transmission and generation companies participate in the ISO market, which is used to allocate transmission space, maintain operating reserves and match supply with demand.

Another central function of the ISO is to provide transparent information about the state of the system and prices. These data points help market participants assess the economics and manage the risks of wholesale power transactions and supply. Timely and accurate information about wholesale markets is the centerpiece of an effective and competitive marketplace. At the same time, economists within the ISO Department of Market Monitoring keep a close eye on market activity, reviewing wholesale prices and watching for potential misconduct.
