New England Power Plants There When Needed, ISO Says

LCG, Jan. 15, 2001ISO New England Inc., the manager of the transmission grid in much of the U.S. Northeast, said on Friday that it is conducting a study on power plant availability in its region and so far the operators of generating units appear to be responding well.

The study, which is expected to be completed in late March, is focusing on what are the drivers for unit outages including the impact of market operations, age, environmental retrofits and other factors, the ISO said.

ISO New England said it has observed that since the wholesale electricity marketplace opened to competition in May 1999, generating units have been responsive to ISO requests and made aggressive efforts to be available to meet peak demand.

The study indicates that power producers conduct maintenance when plants are not likely to be needed, generally during seasonal off-peak periods in the spring and fall.

In addition, ISO New England said it has noted that during short-term peak demand periods that occur during the spring or fall, or when a generator suddenly trips off-line and is unavailable, generators and their operators work vigorously to have the generating units online, maintain system reliability and meet the needs of New England's electricity consumers.

Other observations include that during peak demand summer and winter months, when the weatheris more temperate than forecasted, generators may conduct spot, or short-term maintenance outages, in order to prepare for days when demand is high.

ISO New England said it will post the study on the World Wide Web when it is complete.
