Alstom continues to offer power producers technology-leading solutions to meet changing power needs.
Alstom Gas Power Plants
The ultimate in versatile and clean power generation Offering the widest range of gas-fired solutions to help today’s operators meet increasing complex power generation demands, Alstom offers both proven power plant technology and a unique approach to power plant optimisation, designed to deliver maximum value to customers around the world.
Plant Integrator™ approach Alstom’s unique approach to power plant optimisation is based on a ‘Net Present Value’ (NPV) model that considers six key factors across the plant’s entire lifecycle: •
Proven technology Alstom has been delivering the innovative gas power plants power generation customers need to maximise the return on their investments for more than 70 years. From constructing the world’s first industrial gas-turbine power plant in 1939 to the more than 200 gas power plants delivered to date, Alstom gas clean technologies have kept pace with power producers dynamically changing needs for increased production at lower cost and environmental impact.
• • • • •
Investment Lead time Performance Availability and operational flexibility Retrofit capability Life extension capability
Other key factors, like environmental regulation compliance and fuel flexibility are made a part of the six NPV factors. By using this approach, better measurements can be made regarding the true value of a given construction project and a more comprehensive level of optimisation achieved.

Clean Power, How Alstom is helping you
Our Power generation offering is based on a deep understanding of power markets and our customers’ needs. It is organised around three levers to maximise the return of assets over their entire lifecycle.
It takes competitive assets to keep electricity affordable. We enable power companies to compete successfully in the marketplace and provide affordable electricity to consumers. We help you reduce the cost of electricity through:
• Efciency improvements • CAPEX reduction / scaling up • Capacity Factor increase (renewable) • Lead time reduction • Competitive O&M • Competitive nancing
04
Clean generation is one way of demonstrating environmental responsibility. Another is lowering resource usage, visual impact and noise pollution. In both cases, we can help you meet or exceed regulations and environmental standards. That is why Alstom innovates in the following areas:
• Renewable portfolio • Natural resource optimisation • Pollutants control • • •
(SOx, NOx, PM, mercury) CO2 emission reduction & CCS Land use, visual impact and noise Water intensity reduction & recyclability
Intermittent power generation is a growing challenge of energy security, as is maintaining an aging installed base and adapting it to changing market conditions. We help you tackle both issues so that you can enjoy dependable operations with:

Aluminium and High flexibility
KA13E2: the ideal power plant for the aluminium industry The Alstom KA13E2 combined-cycle power plant represents an ideal power plant for the aluminium industry with its world-class efficiency and possible hot-gas-path inspection intervals of 36,000 equivalent operating hours (EOH) due to Alstom’s innovative dual operating mode capability.
Key facts
Customer benefits
Aluminium production is power intensive so low-cost electricity is vital. The load of an aluminium smelter changes frequently: load swings occur due to anode effects or trips of pot lines. The power plant supplying the facility must be able to maintain a stable industrial grid frequency, independent of the electrical grid.
Low cost of electricity Alstom’s KA13E2 power plant is based on the GT13E2 gas turbine, which has the highest efficiency in its class and a possible hot gas-path inspection interval of 36,000 Equivalent Operating Hours (EOH). Robustness and reliability The stable EV (EnVironmental) combustion system and conventional firing temperatures of the GT13E2 support fast load changes up to 6 MW/s, without penalisation of the engine lifetime The block size of 250 MW gives high redundancy (N-1 and N-2) even to medium-size plants or retrofits •
The KA13E2 is well proven in this industry. They are installed in six dedicated plants powering aluminium smelters, representing 14 GT13E2 units. Our customers include major aluminium producers such as ALBA, DUBAL, SOHAR Aluminium and Rio Tinto Aluminium.

Key facts
Customer benefits
The increasing price of electricity is leading to energy optimisation in steel plants and the use of Blast Furnace Gas (BFG) in gas turbines, which is more efficient than in boilers. The KA11N2 LBtu has been specially adapted to burn waste gases from steel making. These gases can be used to generate power and steam very efficiently. As with all Alstom gas turbines, the turbines that power the KA11N2 offers consistent, stable operation at low and part-load conditions and reduces NO x and CO emissions even at part load.
Fuel flexibility All waste gases from a steel plant can be utilised With a minimum LHV of 1,800 kJ/kg (660 kcal/Nm3) even pure Blast Furnace Gas (BFG) can be burned No need to use natural gas or expensively cleaned Coke Oven Gas (COG) for the gas turbine after start-up Low fuel costs – thanks to being independent of natural gas and COG Rugged combustor, high fuel flexibility, with the ability to burn mixed gases even at ±15% calorific variation
With Alstom’s Plant Integrator™ approach, each power plant is tailor-made to site requirements and integrated into the steel plant – this provides maximum value for the steel plant operator, in both 50 Hz and 60 Hz markets.
