This grant provides ongoing support to the Open Energy Outlook (OEO) Initiative, a multi-disciplinary, open-source, publicly available energy system model collaboration led by scholars at Carnegie Mellon University and North Carolina State University. The OEO Initiative involves input from over 40 consulting external subject matter experts from fields such as policy, electricity, buildings, and transportation, and it provides an open-source platform that makes energy system analysis more accessible to a range of stakeholders and applicable to different geographies and sectors. Grant funds will provide the organizational resources necessary to help grow and sustain the OEO Initiative over the coming years, involving three primary tasks. First, the team will update the open-source modeling platform that the OEO Initiative is based on, called the Tools for Energy Model Optimization and Analysis (Temoa) model, to better represent recent energy policy developments and legislation. Second, the team will develop a strategic plan that charts the longer-term path for their research, fundraising, and operational model, which includes establishing a consortium of funding partners from industry, nonprofits, and other foundations. Finally, the team will participate in research partnerships that will apply and extend the OEO Initiative framework to specific states, sectors, and other regions and countries. These research partnership efforts are expected to train 4-6 graduate students at a variety of institutions deploying the Temoa model. Funds will primarily go towards supporting the Executive Director role in managing the OEO Initiative.
