The largest affordable housing provider in Boulder installed a solar+storage system to provide command post services during emergencies. This case study includes technical and financial details, as well as lessons learned over the course of the project.
A leading nonprofit mobility services provider and emergency second responder invested in resilience upgrades to power critical transportation services for vulnerable populations in the event of an outage. This case study includes technical and financial details, as well as lessons learned over the course of the project.
This guide reviews permitting and interconnection requirements and processes for the development of residential and commercial -scale solar+storage systems in Boulder, Colorado. Created in support of Boulder’s Climate Commitment, this guide aims to advance the installation of solar+storage systems locally, contributing to the city’s goal of being powered by 100% renewable energy by 2030.
A defunct mobile home park in rural Vermont was transformed into the first resilient, zero-energy, affordable modular housing development in the country with solar and battery storage systems. This case study includes technical and financial details, as well as lessons learned over the course of the project.
This report was prepared for activists and foundations who want to understand how battery storage can become an essential new part of their clean energy and climate advocacy. It tries to answer two basic questions: (1) What do we need to know to understand these opportunities? and (2) What actions should we support to realize them?
This report explores the top 10 emerging trends for battery storage across all elements of the energy system, and it recommends over 50 actions that should be taken to accelerate battery storage in these topic areas.
A small municipal utility installed a battery storage system to compliment an existing solar electric system for cost savings and resilient power. This case study includes technical and financial details, as well as lessons learned over the course of the project.
Researchers from NREL and Clean Energy Group found that placing a monetary value on the ability of solar+storage to avoid losses during grid outages can significantly impact project economics and system design.
This collaborative paper by the National Renewable Energy Laboratory (NREL) and Clean Energy Group details the first comprehensive public analysis of the potential size of the commercial behind-the-meter battery storage market in the United States.
This report, commissioned by The Kresge Foundation, the Surdna Foundation and The JPB Foundation, identifies market barriers to deploying solar+storage technologies in low-income markets, and proposes more than 50 grant and investment opportunities that socially minded investors can use to target those barriers.
This series of energy storage procurement guidance documents for municipalities was originally produced to support Massachusetts Department of Energy’s Community Clean Energy Resilience Initiative awardees in energy storage procurement; however, these materials offer useful information for other municipalities to consider as they develop solicitations for resilient, energy storage projects.
Video: How a Municipal Energy Storage Microgrid Works
A new battery energy storage system in the town of Sterling, Massachusetts is saving the Sterling Municipal Light Department’s ratepayers hundreds of thousands of dollars and providing at least 12 days of backup power to the police station and emergency dispatch center to keep first responder operations running, even during extended power outages.
This video showcases the economic and resilient power benefits of the solar+storage system with several interviewees discussing the merits of the project and features an animation segment that explains how the battery storage system works to save money and provide resilient power to the town during an emergency.
