Pools were set up not to challenge the concept of an integrated regulated utility
but as a means of increasing system reliability among independent integrated utilities. In
this way, surplus capacity for one utility would be available to meet demand for another
utility short on capacity. A tight pool is a pooling of utilities with membership restricted
to a specific region. Two tight pools, one for New England and one for New York,
were formed to share generating capacity among pool members for greater system reliability.
