ISO New England Files Testimony for Locational ICAP

LCG, September 1, 2004--ISO New England filed testimony yesterday with the Federal Energy Regulatory Commission (FERC) regarding the development of ISO New England's proposed Locational Installed Capacity (Locational ICAP) market, which is designed to attract new generation on a locational basis to improve electric reliability.

The new testimony follows ISO New England's filing of March 1, 2004, which included a proposal to create four ICAP Regions: Northeast Massachusetts-Boston, Maine, Connecticut, and Rest of Pool. In the subsequent FERC Order issued on June 2, the FERC proposed the division of the Connecticut Region into two locational ICAP Regions (Southwest Connecticut and Rest of Connecticut), to which the ISO agreed in a July 2 compliance filing.

In the June 2 Order, the FERC accepted ISO New England's proposed sloping demand curve and the locational market design; however, it rejected the transition plan and set three general issues for hearing: the parameters of the demand curve, Capacity Transfer Limits (CTLs), and capacity transfer rights (CTRs). The ISO's latest testimony addresses these issues, including a refined analysis of the estimated cost of new, peaking generation in New England.

ISO New England anticipates a final decision on the market's design from the FERC in June 2005 and implementation on January 1, 2006.
