Deutz Power Systems Increases Far East Presence

Gas engine sets by Deutz Power Systems GmbH are increasingly utilized in power generation applications in Far East countries, and to support the growing importance of the Asian energy market, Deutz Power Systems recently announced a new local subsidiary in Singapore that joins the one located in Beijing.

The TCG 2020 V20 gas engine gen-set. In Jakarta, Indonesia, 12 of these gen-sets supply 20 MW of electrical power to Mangga Dua, one of Indonesia’s largest shopping malls, with 4000 shops.

Deutz Power Systems Asia-Pacific (Pte) Ltd. in Singapore sells energy generation plants based on gas and diesel engines all over Asia (except China). The market reaches from Pakistan to the
Philippines and from Japan to Indonesia.

The German headquarters reported that the population of its gas and diesel engines supervised by Deutz Power systems Asia-Pacific has passed the 2500 MW mark, with a range of applications
varying from the energy supply of agricultural and industrial facilities to the utilization of mine gas from coal mines to combined heat and power (CHP) plants for shopping centers.

For example, in Jakarta, Indonesia, with a population of some 8 million inhabitants, 12 TCG 2020 V20 gas engine gen-sets supply one of Indonesia’s largest shopping malls, the Mangga Dua, with an electrical output of 20 MW.

As for China, the subsidiary Deutz Power Systems (Beijing) Co. Ltd. is supervising a total electrical output of about 80 MW. The company has the complete technical know-how needed to autonomously carry out projects in this market and provide the associated services.

Among the projects conducted in China is the implementation of two CHP plants for the energy and water supply of lithium mines. Three TCG 2032 V12 gen-sets in Dongtai and four TCG 2032 V16 gen-sets in Xitai generate a total of 18 MW of electricity for the CITIC Guan project for the extraction of raw materials.

The manufacturer explained that the special characteristics of the location on the salt lake of the Chaidam basin at an altitude of 3000 m — far away from any energy supply — posed a major challenge for the plant setup. In China, Deutz Power Systems has also conducted Carbon Development Mechanism (CDM) projects, where electricity and heat is generated and, at
the same time, unused CO2 emissions certificates can be traded for profit at the exchange.

One such example is in Shanghai, where Deutz has supplied two TCG
2020 V16 gas engines for power generation from landfill gas at the waste dumping station of Shanghai Laogang district. Every day, approximately 6000 tons of waste arrive at the biological
waste treatment plant and is processed to collect landfill gas. This powers the two gas engines, which generate 2.5 MW of electricity.

Another significant CDM project for Deutz Power System is the Duerping Mine of the Shanxi Coking Coal Group, located in Shanxi province covering an area of approximately 2600 km2. It has
been calculated that the 23 billion tons of coal under this area represent almost 80% of China’s total deposits. The Duerping mine alone has coal reserves of 700 million tons and an expected lifetime of 50 years. And the mining field is not only a source for coal — every ton of coal mined yields approximately 18 m3
of mine gas containing methane. Since early 2007, the mine gas at the Duerping mine is collected in a new plant and used to power gas gen-sets for generating electricity and heat, using three TCG 2020 V20 gas engines from Deutz Power Systems. The gen-sets produce a total of approximately 5.2 MW of electricity and
5.3 MW of thermal energy. Thus, the mine can be autonomously supplied with heat and power from mine gas, at the same time avoiding more than 400 000 tons of CO2 equivalent emissions.

As far as the other Asian countries,Deutz Power Systems carried out several other decentralized energy supply projects, for example in Thailand, in cooperation with the Thai sales and service partner Min Sen Machinery Co. Ltd. In the area of Bangkok, Deutz Power Systems supplied two TCG 2016 V16 gas engines for a pig farm. Biogas produced by the pig manure fuels the two units, providing 700 kW of electricity for the farm. The generated thermal energy of 707 kW per unit is used to heat water to 90°C. Thus, the plant’s overall efficiency is higher than 80%.

The farmer also benefits from the fact that emissions are about 40 000 tons less CO2 per year and he is able to sell the surplus CO2 emissions certificates with profit. The excess manure is used
to fertilize the rice and vegetable fields on the 500 hectare site.

Min Sen Machinery Co. Ltd. has built other innovative plants of this type in the provinces of Trang, Changmai, Kamphangpet and Ratchaburi. Thus, the total electric capacity of the biogas units
from Deutz Power Systems installed in Thailand already amounts to 5 MW. The Thai Ministry of Energy estimated that the energy deficit until 2021 accounts for 30 000 MW. Therefore, such projects with agricultural enterprises having integrated biogas plants are considered as an important contribution to efficient and eco-friendly power generation. Thailand plans to cover 8% of its electricity demand with renewable energies by 2008.

As for Bangladesh, Deutz Power Systems supports the local market in cooperation with its sales and service partner Kaltimex Energy Bangladesh (Pvt.) Ltd. The company calculated that the energy produced by its gas engines has already reached approximately 45 MW.

Among the most noteworthy projects, Silverline Composite Textile
Factory, located in Gazipur — a 15 000 m2 textile plant — produces 7500 tons of ring cotton yarn per year, employing about 900 people. Three TCG 2020 V12 series gas engines provide a total
electric capacity of approximately 3.0 MW and a thermal capacity of approximately 2.8 MW
