GE Aeroderivative Gas Turbine Brings Power, Heat, Reduced Emissions to Italian Paper Mill, Surrounding Community: Project Helps Italy Reach its European Union Energy Efficiency and Emissions Goals  (Source: GE Energy)

Cartiere del Garda paper mill and Alto Garda Servizi (A.G.S.) recently celebrated the official opening of the Alto Garda Power combined heat and power plant, featuring a GE Energy aeroderivative gas turbine, that provides an energy efficiency, district heat solution that supports major European Union (EU) goals to reduce emissions.

The project will help the Cartiere del Garda S.p.A. paper mill save money through reduced energy costs by efficiently producing electricity for the factory and additionally dispatching it to the market, producing steam for internal production processes and hot water for the local district-heating network of Riva del Garda. This new district-heating network will heat more than 4,500 houses in the town of Riva del Garda. According to the customer, the power plant project will provide an added benefit of a total displacement of 40,000 tons of CO2 equivalents annually.

“Lowering energy costs means a sharp reduction in total production costs. In order to remain competitive, the paper industry must find ways to reduce high energy costs and save on energy,” said Paolo Mattei, president, Alta Garda Power. “Keeping this in mind, it is worth highlighting the exceptional combustion performance of the new GE LM6000 gas turbine. The atmospheric emissions are half those of the former Cartiere del Garda cogeneration plant and well below the legal limit.”

According to TERNA, the Italian National Grid operator, Italy must import more than 10% of its consumed electricity in order to meet current levels of demand. Due to its efficiency and reliability, the installed GE LM6000® will produce additional power to help decrease Italy’s need to import power. It also will be another step for Italy towards the EU’s goal of 20-20-20. The EU targets call for a 20% reduction in greenhouse gas emissions compared with 1990 levels, a 20% cut in energy consumption through improved energy efficiency and a 20% increase in the use of renewable energy, all by the year 2020.

The Alto Garda Power project was promoted by A.G.S. and Cartiere del Garda, with an objective to replace the old cogeneration, thermo-electrical plant, with a new, modern, technologically innovative plant.

GE Energy’s LM6000 PD Sprint gas turbine generator package is at the heart of the system and generates approximately 46 megawatts (MW) of electricity. The exhaust gases are sent into a boiler, which produces steam that is then directed to a turbine to generate electricity or directly used for either internal production processes or hot water to feed the city’s district heating network.

The LM6000 boasts low emissions levels of 50mg/Nm3 of nitrogen oxide (NOx) and 30 mg/Nm3 of carbon monoxide (CO). As a result, according to the customer, the Alto Garda Power plant will see an annual savings of 40,000 tons of equivalent petroleum and a significant reduction of CO and NOx emissions, delivering a major benefit for air quality and the environment.

GE’s LM6000 has a power output of 45.74 MW and 41% efficiency and is able to run 24 hours a day, seven days a week, all year long. Its high electrical efficiency allows the plant to provide the same power output as previously while consuming less gas, which translates into a substantial savings.

“Paper manufacturers have particular needs that our turbines are well-suited to meeting. Because of their continuous production cycles, they need highly reliable machinery that can operate around the clock. The LM6000 is a proven model, with approximately 800 GE LM6000 gas turbines in use at different facilities around the world, making it a great choice for the paper industry,” said Darryl Wilson, president and CEO of GE Energy’s aeroderivative gas turbine business. “This project also is accompanied by a 12-year contractual service agreement, which allows us to ensure quick response times in the event of anything unexpected.”
