Distributed Energy Resource Growth

Note from the editor

Distributed energy resources, including rooftop solar, battery storage and electric vehicles, are experiencing significant growth in the U.S. as the power sector evolves to a cleaner, less centralized future.

That growth is expected to provide enough cumulative capacity by the early 2020s to flatten power sector peak demand, according to GTM Research.

It also presents tremendous opportunities for utilities if they can act quickly, a recent Boston Consulting Group report found.

But what's propelling the rise of distributed resources and what are the obstacles to more growth?

This trendline examines the experiences of various utilities, vendors, states and grid operators to provide a comprehensive picture of a burgeoning field at the heart of the energy transition.

Ensuring DER inclusion in capacity markets may require a rethink of resource adequacy

The growth of customer-owned resources is forcing system operators and aggregators to see their value as reliability tools and rethink the concept of resource adequacy.

Increasing renewables and DER demand new reliability approach, but California is falling short, groups say

Resource adequacy's planning reserve margin worked when supply and load were stable, but new system realities demand a more dynamic approach to protect reliability, groups say.
