NASCAR's recent race in San Diego showcased an innovative approach to power management, highlighting the sport's commitment to sustainability and technological advancement. The event's unique requirement for a self-sufficient power grid, due to its location on a military base, led to the development of a microgrid system, a collaboration between NASCAR and ABB. This system, as explained by ABB's Chris Shigas, is a network of microgrids that combines battery energy storage systems (BESS) with traditional diesel generators, offering a more efficient and sustainable solution. The microgrid's design, born from street course events in Chicago, effectively manages power generation, transmission, and distribution, ensuring a stable and reliable energy supply for the race. This approach, likened to a 'roving city into a market', can be adapted for remote race controls and is a significant step towards NASCAR's sustainability goals. The San Diego race weekend served as a proof of concept, with ABB's BESSes powering all motorsport activities, from pit road to fan experiences. The collaboration between NASCAR, ABB, and other partners, such as Suburban Propane, demonstrates a holistic approach to sustainability, aiming for net-zero operating emissions by 2035. This includes the use of renewable energy, low-carbon bioethanol fuels, and recycling, all while maintaining the integrity of the racing product. The event also featured an innovative display, the NASCAR Grid Control, which provided real-time data on sustainability efforts, allowing fans to see the behind-the-scenes work and decisions made by NASCAR and its partners. This transparency is a step towards engaging enthusiasts and showcasing the sport's commitment to environmental responsibility. The San Diego race weekend was a testament to NASCAR's ability to balance technological innovation with sustainability, setting a precedent for future events and potentially influencing the broader motorsport industry.
