ESTAP is a project of CESA

Clean Energy States Alliance (CESA) is a non-profit organization providing a forum for states to work together to implement effective clean energy policies & programs:

– Information Exchange

– Partnership Development

– Joint Projects (National RPS Collaborative, Interstate Turbine Advisory Council)

– Clean Energy Program Design & Evaluations

– Analysis and Reports

CESA is supported by a coalition of states and public utilities representing the leading U.S. public clean energy programs.

ESTAP* Overview

Purpose: Create new DOE-state

energy storage partnerships and advance energy storage, with technical assistance from Sandia National Laboratories

Focus: Distributed electrical energy storage technologies

Outcome: Near-term and ongoing project deployments across the U.S. with co-funding from states, project partners, and DOE

ESTAP Key Activities

• Disseminate information to stakeholders

• ESTAP listserv >500 members

• Webinars, conferences, information updates, surveys

• Facilitate public/private partnerships at state level to

support energy storage demonstration project

development

• Match bench-tested energy storage technologies with state hosts for

demonstration project deployment

• DOE/Sandia provide $ for generic engineering, monitoring and

assessment

• Cost share $ from states, utilities, foundations, other stakeholders
