By bringing the power source onsite, GE delivers efficient, reliable energy to municipal districts, manufacturing plants, hospitals, airports, shopping malls, data centers, sports arenas, universities, hotels, office buildings, and a variety of other operations.
For large facilities that serve entire communities, like hospitals, combined heat and power (CHP) systems from GE offer electricity and thermal energy production onsite, eliminating the need to purchase electricity while separately burning fuel in an onsite boiler to produce heat.
CHP also helps the facility avoid electricity losses that can occur in transport, transmission, and distribution processes from the point of power generation to the facility. With CHP, facility operators can expect greater efficiency, profitability, and environmental benefits, including:
Reliable combined heat and power systems for hospitals and other large facilities that serve a community are essential to maintaining operations. When a large facility operator turns to GE for a CHP solution, a variety of aeroderivative gas turbines can be employed in generation efforts, depending on site requirements and operator needs and expectations.
With the broadest gas turbine for CHP product portfolio in the industry, GE is uniquely positioned to provide its customers with the right products to provide the required ratio of power to heat for their CHP systems.
The LM2500 is the most reliable aeroderivative gas turbine in the world, featuring reliability consistently above 99.8%.
Recommended for combined cycle, onshore and offshore power generation, mechanical drive, and cogeneration, the LM2500 power plants feature 21-34 MW simple cycle output, up to 38.5% efficiency and accommodate a wide variety of fuels. It also comes with optional clutch-less synchronous condensing.
The LM6000 allows you to operate on a wide variety of fuels—including natural gas, LPG (propane and butane), isopentane, ethanol, diesel, and Coke Oven gas.
This allows you to quickly switch between fuels to save money, all without stopping or a reduction in power. It has a 45-58 MW net power output and up to 41.3% net efficiency. Its start time for a simple cycle is less than 5 minutes, and its ramp rate is 50 MW/minute. The LM6000 offers 99%+ start and operational reliability, alongside 98% availability. Its fast start allows operators to differentiate their dispatch capability, and its dual-fuel capabilities provide fuel flexibility and help customers meet emissions limits.
The LMS100 aeroderivative gas turbine is one of the highest-quality simple-cycle efficiency gas turbines in the world.
Its simple cycle output is 117 MW, and its combined cycle output (1x1) is 142 MW. The LMS100 features up to 44.2% net efficiency, 99.6% reliability, and 96.7% availability. Its start time for a simple cycle is less than 8 minutes, and its ramp rate is 30 MW/minute. The LMS100 can provide power at part-load as efficiently as most gas turbines at full load, and can operate with very little power loss, supporting the grid in times of high demand. Its intercooled gas turbine system provides rapid startup, with an 8-minute start to full load and emergency ramp speeds of up to 500 MW/minute, and construction includes a modular “supercore”, which can be exchanged in less than four days to enhance plant availability.
Recommended for mobile power applications available within three months and fast-track or short-term duration projects, the TM2500 50 Hz and 60 Hz solutions have a 33.6 MW average power output and 36.7% average net efficiency.
Its start time for a simple cycle is fewer than 5 minutes, and its ramp rate is 20MW/minute. The TM2500 is mobile and easy to transport. Its small block size allows good part-power turndown and efficiency. It is relocatable if project requirements change, and it comes with optional clutch-less synchronous condensing.
Up to 95% thermal efficiency means operators of large facilities can realize both cost and energy savings when they implement CHP generation. Burning less fuel to help meet energy requirements and reducing thermal and electrical costs can translate to as significant expense reduction and up to 40% energy savings using waste heat from turbines. Less reliance on imported fuel, reduced infrastructure investment and more network stability also mean monetary savings.
Using the LM2500 aeroderivative gas turbine for CHP generation, for example, facility operators realizing a 40% energy savings also save about $19 million per year versus what they would spend on power generated by electricity and steam purchase or production as separate resources.

"Our LM6000 aeroderivative gas turbine is a proven industry-leading solution for district energy and CHP needs. We’re proud to partner on the TECO system, which is a model for others to follow both in the United States and globally."
GE Gas Power representative
The CHP system pumps chilled water and steam throughout the facility with a circulatory system of underground pipes. It’s the largest chilled water system in the U.S. and the heart of the center’s climate control. With GE’s CHP system, Texas Medical Center cut its fossil fuel consumption 61% and significantly reduced CO2 emissions. With CHP, the complex projects a savings of more than $200 million over 15 years.
In 2020, GE signed a new contract to service two existing GE LM6000PD aeroderivative gas turbines (operational since November 2011 and March 2012) that provide power and chilled water to Bangkok’s Suvarnabhumi International Airport. District Cooling System and Power Plant (DCAP), the largest district cooling plant in Thailand, signed the service agreement to improve the performance efficiency of the 110 MW plant.

Being the OEM provider for our current fleet, we selected GE as the service provider to help us increase the full potential of our plant assets. We know that GE has a proven track record of providing high-quality technology and services, and with this service agreement, we trust in the company's technical expertise and its regional capabilities in engineering and technical support.
Mr. Suthep Ruangpornwisuth
Director Acting General Manager, DCAP
GE will assist with ensuring the stability and reliability of the international airport’s power production and cooling system, while reducing the overall cost ownership of the plant, acting as OEM for the turbines and plant and performing all of the plant’s major maintenance needs over the next five years.
GE’s LM2500+ G4 CHP application serves 250 buildings across the Texas A&M College Station campus. Completed and commissioned in 2013, the system covers 19 million square feet of air-conditioned classroom, research, housing, and facility space. Texas A&M’s CHP system is configured to remain fully functional during power outages, allowing critical campus functions to continue without interruption.
