Interregional long range adequacy overview

The resource adequacy of Northeast Power Coordinating Council (NPCC) and its neighboring Regions was estimated for the years 2007 -2011, measured by calculating the annual Area Loss of Load Expectation (LOLE) through a consistent multi-area probabilistic reliability assessment. The evaluation considered the uncertainty in forecasted demand, likely completion of proposed transmission and generation projects, anticipated retirements, forced and scheduled outages of generation facilities, demand response programs, and the estimated impacts of operating procedures. The potential for resources expected from proposed market mechanisms designed to provide for future resource adequacy was considered. The evaluation also included the impacts of Sub-Area transmission constraints, and incorporated, to the extent possible, a detailed reliability representation for Regions bordering NPCC.
