As of November 19, 2014, Vanderbilt is coal free! Vanderbilt University currently has an on-campus co-generation, natural gas-fueled power plant which produces 23% of our electricity and 100% of our steam, servicing 12 million square feet of building space. This steam is then used for 90% of campus heating, sterilization, and 40% of campus cooling. This cogeneration process is quite efficient: heat, which would otherwise be a wasted byproduct of electricity and steam generation, is used to produce more steam and hot water. The remaining 77% of electricity consumed at Vanderbilt is purchased directly from Nashville Electric Service from Tennessee Valley Authority (TVA).
The plant is now fueled by 100% natural gas. The conversion of the plant replaced the coal-fired boilers with natural gas boilers, retaining the same power generation capacity. The iconic smokestack, silo, and other coal infrastructure were demolished in the Spring of 2015 as part of a broader renovation to modernize the plant.
