Form EIA-411, ?Coordinated Bulk Power Supply Program Report,?

The Form EIA-411, ?Coordinated Bulk Power Supply
Program Report,? collects information from the Nation?s power system
planners about the electricity supply, both capacity and energy, that is
needed to serve current demand and for future growth.

The reported data can be used to examine such issues
as: the reliability of the U.S. electricity system; projections which
assess future demand growth and plans for constructing new generating
and transmission facilities; and consequences of unavailable or
constrained capacity on usage of the existing generation base.

Reliability of the electric power system covers
three areas: the security of the electrical systems; the usage of
proper operational practices that adhere to mandatory standards; and the
ability to plan for adequate supply to meet future demand. Data
collected on the Form EIA-411 focuses on planning for adequacy of
supply. Separately, the Department of Energy collects information
covering security and selected operational practices under the Form OE-417, "Electric Emergency Incident and Disturbance Report."

The information on this page includes historical
(with and without projections) and current data (with projections) for
the reported year:

• peak load
• monthly peak hour demand
• net energy for load
• net internal demand and planned capacity resources

Only projections, but no historical data, are reported for:

• high voltage transmission line planned additions

The data provided here are aggregated by the North
American Reliability Corporation (NERC) using data provided by the
regional entities within NERC that oversee the development and
implementation of the mandatory national and regional reliability
standards. There are currently eight regions covering all of Canada and
the contiguous United States plus a small part of Mexico (Baja
California Norte) in North America. The data presented here is for the
United States. For data years prior to 2005, 10 NERC regions are
indicated, however, from 2005 on, there are 8 regions. (See maps at the
top right). Users should expect some differences in geographic
reporting coverage from these regional realignments.
