Understanding Solar+Storage: Answers to Commonly Asked Questions About Solar PV and Battery Storage
This guide addresses commonly asked questions about solar PV and battery storage (solar+storage) technologies. It is based on the results of a survey identifying the most common knowledge gaps around solar and energy storage.
New York City’s peaker power plants have a disproportionate impact on the city’s most vulnerable people. Replacing peaker plants with a system of localized renewable energy generation and battery storage can reduce greenhouse gas emissions, reduce energy bills, improve public health and equity, and make the system more resilient in the face of increased storms and climate impacts.
Financing Resilient Power is a groundbreaking philanthropic effort – a $3.3 million initiative of The Kresge Foundation to accelerate the market development of solar+storage technologies in historically underserved communities. The Foundation’s investment – developed with Clean Energy Group, which will manage the effort – represents the first time a U.S. foundation has committed to use both its grantmaking and endowment resources in a comprehensive strategy to bring these new clean energy technologies to affordable housing and critical community facilities.
“Home Health Care in the Dark,” a new report by Clean Energy Group and Meridian Institute, examines the risks associated with power outages for individuals reliant on electricity for in-home medical and mobility equipment. As more people are encouraged to receive health care at home rather than in hospitals and nursing homes, we need resilient power solutions that keep vulnerable residents safe in the next power outage.
Solar with Justice: Strategies for Powering Up Under-Resourced Communities and Growing an Inclusive Solar Market
This report aims to accelerate the implementation of solar in under-resourced communities in ways that provide meaningful, long-lasting benefits to those communities. The recommendations in the report set a path forward for increasing solar deployments that result in significant economic, equity, and environmental improvements.
Resilient Southeast is a series of reports exploring the obstacles and opportunities for solar PV and battery storage to strengthen the resilience of communities throughout the Southeast. The series evaluates the current policy landscape and economic potential for solar and battery storage to provide clean, reliable backup power to critical facilities in five cities: Atlanta, GA; Charleston, SC; Miami, FL; New Orleans, LA; and Wilmington, NC. When the economic value of resilience is accounted for, solar+storage was proven to be a positive investment for all locations and building types examined.
This report describes the process of enabling use of state energy efficiency funds to support the deployment of energy storage with performance incentives offered for demand reduction. The report summarizes the economics of battery cost/benefit calculations, examines key elements of incentive design, and makes recommendations for other states to follow the example of Massachusetts and incorporate storage into their own efficiency plans.
Vermont’s largest utility installed a solar+storage microgrid in Rutland, VT that saves hundreds of thousands of dollars and can supply backup power to an emergency shelter. This case study includes technical and financial details, as well as lessons learned over the course of the project.
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.
A new utility program in Massachusetts has dramatically changed the economic landscape for battery storage in the state and created a pathway to deliver the benefits of storage to affordable housing providers and residents.
Video: How a Municipal Battery 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.
