The Economics of Battery Energy Storage: How Multi-use, Customer-sited Batteries Deliver the Most Services and Value to Customers and the Grid (Technical Appendix)
Utilities, regulators, and private industry have begun exploring how battery-based energy storage can provide value to the U.S. electricity grid at scale. However, exactly where energy storage is deployed on the electricity system can have an immense impact on the value created by the technology. With this report, we explore…
The Electricity System Value Chain
The Rocky Mountain Institute (RMI) has developed a framework that describes the major activities required for the electricity grid to function. Because the grid system network is not a linear value chain it becomes more difficult to see how a node can be removed or where new value can be…
The Economics of Load Defection: How Grid-Connected Solar-Plus-Battery Systems Will Compete with Traditional Electric Service, Why it Matters, and Possible Paths Forward
In particular, we sought to answer two core questions:1. Lowest-Cost Economics: When grid-connected customers have the option to source their entire load either from a) the grid, b) a solar- plus-battery system, or c) some combinationof the grid, solar PV, and batteries, how does that configuration change over time based…

How to Calculate and Present Deep Retrofit Value: A Guide for Owner-Occupants (Executive Summary)
This might come as a surprise to some, but energy efficiency is about more than energy, and deep energy retrofits, which achieve superior energy savings over conventional retrofits and can reduce a building’s energy consumption by 50 percent or more, offer bottom-line benefits for business beyond energy cost savings alone.
