Reducing Storage Soft Costs

Sustainable CUNY's Smart DG Hub, together with technical advisors including DNV-GL, with support from the New York State Energy Research and Development Authority, is engaging in efforts to reduce the soft costs of installing energy storage systems by facilitating the development of transparent and streamlined permitting processes. The initial focus is New York City, with assistance provided as needed to other AHJ’s throughout New York State. The first phase of this project included developing a permitting guide for outdoor Li-ion Energy Storage Systems (ESS). 

Recent focal areas included the development of content for the state-wide permitting guidebook. Currently the DG Hub's platform is collaboratively working on the creation of a data utilization guide for UL 9540A large-scale fire testing that will facilitate the application of test data towards permitting criteria for both outdoor and indoor ESS. Partners include the Underwriter's Laboratory (UL), NYC Department of Buildings, the Fire Department of New York, Subject Matter Experts (SME's), industry leaders and AHJs to create a streamlined pathway to integrating storage into the New York market.

Large-Scale Fire Testing Data Utilization Guide

The Smart DG Hub has initiated a fast track collaborative effort that brings DOB and FDNY representatives together with SME’s from various research, engineering, and fire protection institutions in order to discuss application of UL 9540A large-scale fire safety testing results to permitting requirements for energy storage systems in NYC. View the kickoff presentation This group is meeting weekly throughout the Spring of 2019 to systematically address the key topics of Explosion, Toxicity, Thermal Runaway, Fire Spread and Performance Based Design.
