Description

This is a Sources Sought Notice (SSN) issued by the Alliance for Energy Innovation, LLC (Alliance). The purpose of this SSN is to conduct market research and gather information on the current capabilities of potential sources to provide expert development and technical advisory and training services for the Sienna software to advance NLR-prioritized platform features in support of NLR’s energy systems research and technical assistance programs.

Sienna is an open-source energy systems modeling platform developed and stewarded by the National Laboratory of the Rockies (NLR).
