To run into the planned electric, heating and cooling load growth of the Campus, UES implemented a $73.25 one thousand thousand phase of the UES Primary Program to install a 45 MW Combined Heat and Power (CHP) system. TAMU was only 1 of nine recipients nationwide to receive a DOE grant to help finance this $73.25 million major CHP organization upgrade. This $ten million DOE grant awarded to TAMU helped fund the project. The system will produce electricity to serve a significant portion of campus power needs and steam for heating and cooling of campus facilities. The CHP organisation efficiency is lxx% or greater and significantly improves the overall operating efficiency, reliability and emissions profile of the University. This CHP organization consists of a GE LM2500 +G4 natural gas‐fired combustion turbine with a 210,000 lb per hour EIT rut recovery steam generator, together with a Dresser‐Rand backpressure steam turbine, with 600 psi input and twenty psi exhaust steam serving campus heating loads. This new 45 megawatt CHP power and steam generation capacity replaces the previous generation of CHP equipment and collectively with an existing 5 megawatt steam turbine generator; TAMU has fifty megawatts of power generation, together with purchased power capacity to serve 23 meg gross square feet of facilities and over 5,000 acres on the TAMU campus. The system operates at a rut rate of 8,100 mBtu/ MWh and at approaches lxx% efficiency.

The new CHP constitute is an integral component of comprehensive mission‐critical utilities and free energy services provided at TAMU, which includes utility production and distribution combined with comprehensive demand‐side energy management. CHP has been an of import component that has made it possible for TAMU to reduce energy consumption past over forty percent per gross per square foot over the final 10 years, resulting in close to $140 million cost avoidance. Equally a result of the CHP Projection completed in 2012, purchased energy cost avoidance of over $6 million annually has been accomplished through more than efficient power and thermal energy generation, together with a meaning reduction in GHG emissions. The new gas turbine generator and heat recovery steam generator were placed in operation in August 2011, with the new steam turbine generator bachelor for performance in March 2012.

High pressure, superheated (600 psi, 750F) steam is produced by the estrus recovery steam generator (HRSG) using gas turbine exhaust, together with supplemental firing capability, to provide 210,000 lb/hr in steam generation capacity. The 600 psi steam is used to bulldoze a dorsum pressure turbine to generate additional electricity while providing depression pressure (xx psi) exhaust steam for heating hot water and domestic hot water service to campus. 600 psi steam generated in the HRSG is also used to drive steam turbine‐driven chillers along with electric motor‐driven chillers, and provide commune cooling to nineteen million gross foursquare feet of conditioned facilities on campus.

The CHP system provides up to 70 percent of the campus heating for heating hot h2o, campus steam distribution, and domestic hot water uses and up to 35% of the academy's cooling requirement through the use of steam turbine‐driven chillers. In addition to providing estrus to serve seventy per centum of the total campus heating demand and the campus steam distribution arrangement, the CHP system also provides estrus to serve domestic hot water for all student housing, dining facilities, and a number of other general use buildings. TAMU has the adequacy to sell electricity back to the filigree and has done so at times when loftier thermal loads on campus are combined with relatively depression electrical need, simply this is only a very small percentage of the time during cold wintertime weather condition. TAMU is in the procedure of designing a 3 million gallon thermal storage tank that will be operational in 2015 and volition provide the capability to keep CHP power generation base loaded at all times.

Earlier this CHP arrangement upgrade, the university operated a previous generation natural gas‐fired combustion turbine, rut recovery steam generator, and steam turbine‐driven generator. The new CHP system upgrade increased production capacity, reliability, and efficiency, while significantly reducing GHG emissions. The CHP arrangement in the Central Utility Institute at Texas A&M University is a model institute for loftier reliability, efficiency, safety, and cleanliness.
