Macedonia Prime Minister Nikola Gruevski has formally opened the country’s first natural gas cogeneration plant certified for international carbon credit financing in the capital city of Skopje.

The plant, powered by GE’s Jenbacher gas engines, is Macedonia’s first commercial natural gas-fueled combined heat and power (CHP) project completed within the international “Clean Development Mechanism” (CDM). Established under the Kyoto Protocol, this climate protection programme provides global financial support for alternative energy projects that reduce CO2 emissions in developing economies.

The opening of the power plant is part of the Balkan nation’s initiative to install more efficient industrial and district heating facilities that will help improve regional energy reliability and reduce greenhouse gas emissions. The plant’s power will support the operation of local steel factories in the Zelezara Skopje industrial park.

The Skopje plant has an electrical output of 30.4 MW and 13.6 MW thermal output as hot water and additionally 19.5 t/h of saturated low pressure steam, generating a total of 56.9 MW.

Thanks to the combined production of power and heat, the plant’s overall efficiency is 80.5 per cent. By installing GE’s cogeneration technology instead of separate electrical and thermal power equipment, operators receive primary energy savings of roughly 40 per cent through reduced fossil fuel consumption. Also, since CHP systems are located much closer to the end-user, energy transportation losses are also reduced or eliminated.

“Austrian Trade supports export projects in the field of climate protection. Working together with various Austrian companies, we are actively contributing to the achievement of Austria’s Kyoto Protocol goals,” said Anita Bavdaz, Austrian Commercial Attache in Macedonia for the Austrian Federal Economic Chamber.

“I am particularly pleased that GE’s Jenbacher gas engines —a trailblazing technology necessary for countless successful CO2 reduction projects—is playing a crucial role in supporting the emissions reduction goals of many European countries. The new CHP plant in Skopje is a perfect example of that commitment.”

According to the customer, Skopje’s new CHP plant is expected to earn about 185 000 Certified Emission Reduction (CER) credits a year, which corresponds to a projected reduction of the equivalent of 185 000 metric tonnes of CO2. Selling the carbon credits will help the operator ensure the financial viability of the project.

While all the power and the steam gained from the power plant’s waste heat will be used for steel production activities at the site, any excess thermal power during the summer months will be fed into the district heating grid for the city of Skopje.

The Skopje project was developed by Camco International, a UK-based international carbon credit financial services company. Austrian Trade at the Austrian Federal Economic Chamber, Austria’s official foreign trade promotion organization, also provided financial support. The CHP plant was built by Energetski Institut. GE supplied 10 Jenbacher 620 type engines with Leanox lean-mixture combustion and engine control systems, as well five steam generators and spare parts.

In addition to reducing Macedonia’s dependence on imported energy by increasing local energy efficiency and reliability, the CHP plant will help mitigate the local environmental impacts of energy and steel production.

“The project enters service at a time when many European countries are expanding the use of cogeneration systems for industrial and district heating purposes to boost energy efficiency and reduce greenhouse gas emissions,” said Neven Pecotic, GE Energy Country Executive, Macedonia.

Caterpillar introduces Cat Reman generator ends

Caterpillar Inc. has announced the introduction of a family of remanufactured generator ends for standby, prime and continuous power applications using C32 and 3500 series Caterpillar engines.

The first wave of remanufactured generator ends include 34 part numbers, which are available world-wide in 60Hz and 50Hz packages with ratings up to 2.5 MW.

The Cat Reman generator end was designed with the customers’ needs in mind. An affordable product support option, the remanufactured generator ends come with a factory warranty and same-as-new quality.

All critical engineering updates get incorporated in a controlled manufacturing environment. This allows customers to reduce overall operating costs by taking advantage of the multiple lifecycles built into every Caterpillar product.

In addition, Cat Reman generator ends are priced lower than the price of new because like all Cat Reman products and components, affordability and serviceability are two main drivers for every new product launch.

The C32 and 3500 series engines have been used for applications ranging from distributed generation to prime power for remote communities, industrial processing plants and rock crushing applications.

The advantage of investing in a remanufactured generator end will allow for the most diversity in product coverage while at the same time offering reliable power at the right time and the right place.

“Our customers wanted an economical solution for their prime power application needs,” said Doug Hampton, Commercial Manager for Cat Reman. “In today’s economy, customers expect Caterpillar to deliver products that offer improved performance, low fuel consumption, uncompromised serviceability and systems integration that not only meets their unique set of priorities, but also comes with a price tag that doesn’t pinch their pocketbook. We listened to these customer demands and this is our solution.”
