Kaplan, O. AND M. Isik. Introducing COMET: City-based Optimization Model for Energy Technologies Application to New York City. IEA-ETSAP SUMMER 2020 SEMI-ANNUAL MEETING, NA, July 02 - 03, 2020.

Impact/Purpose:

Office of Research and Development at U.S. Environmental Protection Agency developed City-based Optimization Model for Energy Technologies (COMET) which is designed to examine energy consumption and management scenarios under various environmental policy scenarios implemented at city- and state-level. Initial application of the COMET is piloted in New York City. As of today, COMET uses the MARKAL (MARKet ALlocation) energy-environmental-economic optimization framework to determine the technology investment choice and related fuel consumptions for end-use energy demand sectors such as buildings and transportation. In addition, the model covers supply curves for primary energy carriers including fuel oil, natural gas, coal, hydrogen, and other renewable resources. In summer 2020, we will be converting from MARKAL to TIMES framework. Energy technologies (e.g., power plants, refineries, combined heat and power (CHP)) are deployed based on their initial capital cost, variable and fixed operation and maintenance costs, and parameters such as efficiency, availability, capacity factors. COMET determines the technology investment level and related fuel consumption that results in least total system-wide discounted cost while keeping the constraints (sector-wide or systemwide emission limits, renewable or electrification standards etc.) under pre-set levels for the period between 2010-2055. The electric generating units in New York State (both base and peaking units) are included in the model. Using scenario analyses, the model can also be used to explore how the least cost pathway changes in response to various input changes, such as the introduction of new energy efficient technologies or a new policy to stimulate emission reductions. The COMET will enable users to analyze portfolio of technologies that meets building and transportation sector energy demands by facilitating case studies in other cities.
