While equity investors bring cash and risk appetite, debt typically funds 50-75% of project costs. But how do lenders today actually get comfortable with BESS and hybrid investments, what does it mean for project developers, and what the heck does the term “bankable” really mean?. This Practice Note discusses changes to financing structures for battery storage projects after the enactment of the Inflation Reduction Act. This Note also discusses the fixed and variable revenue sources available to battery storage projects based on the benefits they offer to electricity. . Large scale energy projects integrating battery storage require significant capital. Global energy storage capacity additions exceeded 15 GW in 2024, with lithium-ion battery costs declining 90% over the past decade to. .

As part of NLR's Storage Futures Study, dGen modeled customer decisions about whether to adopt distributed storage paired with PV under different scenarios. dGen found battery costs and high value of backup power are the biggest drivers of distributed storage deployment. . These publications—including technical reports, journal articles, conference papers, and posters—either focus on or were heavily informed by the Distributed Generation Market Demand (dGen™) Model or its predecessor, the Solar Deployment System (SolarDS) Model. As part of NLR's Storage Futures. . Unlike traditional centralized systems, distributed storage offers flexibility, efficiency, and seamless integration with renewable energy—making it increasingly vital across urban, rural, and industrial settings. Distributed energy storage refers to deploying energy storage systems near end-users. .
