Key issues in integrated resource planning for electric utilities

Integrated resource planning (IRP) is a means for utilities and state regulatory commissions to consistently assess a variety of demand and supply resources to cost-effectively meet customer energy-service needs. The authors review recent progress in IRP and identify the need for additional work by utilities, regulatory commissions, and other organizations. They point out that IRP as a planning and regulatory process can also greatly reduce the uncertainties and risks faced by utilities and state public utility commissions. Such benefits occur because of the diversity of resources considered, public involvement in the planning process, and cooperation among interested parties
