We make power possible for people around the world.

Steam Power puts a century of expertise to work every day, with local teams in more than 70 countries around the world. In growing economies like India, China, Latin America, Southeast Asia, or Africa this means affordable power, local jobs, and better infrastructure

Over the next 10 years, 25% of all future power capacity additions will be coal or oil-fired steam power plants. GE's Steam Power Systems has installed 30% of the world’s steam turbine capacity, 50% of the world's steam turbines for nuclear power plants, and 30% of the world’s boilers. 

Smarter, Cleaner, Steam Power

With nearly 900 billion tons of reserves, coal power remains an integral part of today’s energy mix that includes renewables as well as gas power generation. Currently, 40% of the world’s electricity comes from coal power and that amount is predicted to decrease only slightly—to 30%—over the next decade. 

As the world’s need for accessible power grows, coal power plants will continue to be a vital way to meet this demand. However, to limit emissions, it is essential that coal-fired power plants provide maximum efficiency and rely on leading air quality and pollution control technologies. GE’s Smarter, Cleaner Steam Power initiative aims to do just that. We are dedicated to ensuring coal power plants are as efficient as possible and to limiting their effects on the environment through innovative, effective emission reduction technologies.

To respond to the power needed worldwide, we’ve developed a portfolio of Smarter, Cleaner Steam Power technologies to meet global electricity needs.


Higher efficiency can lead to both improved economics and reduced greenhouse emissions from coal power. Our ultra-supercritical technologies achieve the highest efficiency rate at a coal-based power plant, delivering 47.5% against the global average of 33%. Each percentage point improvement in efficiency reduces CO2 emissions from coal power plants by 2%.

As a leader in ultra-supercritical steam technology, GE continues to push the limits of our best-in-class steam technology even further. With higher steam parameters and higher efficiency rates, GE is the first-to-market with advanced ultra-supercritical technology. We call it SteamH.


What makes SteamH so impressive? It can deliver an additional 1.6 percentage points of efficiency beyond the best technology in operation today, driving towards 50% efficiency. For a 1000MW advanced ultra-supercritical plant in Asia, for example, this provides an economic benefit of $80M in additional value.

SteamH is based on the proven performance of GE’s ultra-supercritical steam technology that can deliver up to 47.5% efficiency rates—significantly higher than the global average of 34%. Our advanced ultra-supercritical technology surpasses the benchmarks set by OECD for pressure, temperature, and emissions requirements, delivering higher efficiency coal plants with less impact on the environment.


GE is proud to have 80 years of experience and the broadest range of air quality control systems (AQCS) for coal power. Our technology can address all the sources of non-greenhouse gas emissions, like NOx, SOx and particulate matter from any coal-fired power plant. We can meet and exceed the world’s strictest emissions regulations.

Cleaner air means a higher acceptance of coal-fired plants in local communities, and equally important, by lenders and financial institutions—leading to better financing terms for our customers.


What do you get by combining the physical strengths of GE’s coal-fired steam plant technology with our industry-leading digital capabilities powered by Predix? Better performance, greater efficiencies, and improved reliability of existing and future coal power plants.

For example, Asset Performance Management (APM) continuously monitors steam plant equipment health, enabling operations teams to make decisions that enhance plant performance, reduce unplanned downtime, and extend plant life with minimal capital investment.

When steam plants are operating in grid demand mode, they are required to ramp up faster and more often than they were originally designed to—making real-time monitoring especially important. Our Digital Power Plant software interprets data from more than 10,000 sensors to improve coal-fired steam power plant performance. The results?  A 1.5% increase in efficiency and allows for 5% less unplanned downtime and 3% lower CO2 emissions.

It all adds up

All of this translates to lower operating costs for our customers; these lowered costs (and lowered emissions) along with higher efficiency are more attractive to export credit agencies and lenders. GE continues to work with GE Capital Energy Financial Services as well as third parties to fund cleaner energy projects. We also partner with governments and international organizations to identify new funding.
