The Integrated Grid

The electric power system is changing with the rise of distributed energy resources (DER) connected to the distribution system. In many settings these distributed resources already affect the grid, and their projected expansion may significantly change the technical, operational, environmental, and financial character of the electricity sector.

To realize fully the value of distributed resources and to serve all consumers at established standards of quality and reliability, the need has arisen to integrate DER in the planning and operation of the electricity grid and to expand its scope to include DER operation – what EPRI is calling the Integrated Grid.

EPRI has begun work on a three-phase initiative to provide stakeholders with information and tools that will be integral to four key areas of collaboration. The first two phases of work have been explored in the following titles: 

The Integrated Grid: Realizing the Full Value of Central and Distributed Energy Resources.

The Integrated Grid Phase II: Development of a Benefit-Cost Framework.

The intent of these papers is to align stakeholders on the main issues while outlining real examples to support open fact-based discussion. Input and review were provided by various stakeholders from the energy sector including utilities, regulatory agencies, equipment suppliers, non-governmental organizations (NGOs) and other interested parties.




Action Plan

An integrated grid that optimizes the power system while providing safe, reliable, affordable, and environmentally responsible electricity will require focused collaboration in four key areas.

Next Steps

EPRI has begun work on a three-phase initiative to provide stakeholders with information and tools that will be integral to the four areas of collaboration.

Key Points

Several requirements are recognized when defining an integrated grid. It must enhance electrical infrastructure, must be universally applicable and should remain robust under a range of foreseeable conditions.
