To enable the renewable energy-based microgrid, the project team determined that a battery energy storage system (BESS) needed to be incorporated into the concept. At IND, BESS will help support microgrids by ensuring resiliency throughout the day and reducing utility power usage. . Primary Energy Consumer: HVAC systems dominate terminal energy use, requiring constant operation to maintain precise temperatures across massive spaces. These systems work harder during extreme weather, managing humidity levels and maintaining air quality for thousands of travelers daily. Lighting. . The study examines seven distinct categories of renewable energy: solar collectors, solar photovoltaic systems, wind energy, wave energy, tidal energy, hydro energy, and geothermal energy.
