PT Kaltimex chose NTB Province for its ambitious target of achieving Net Zero Emissions by 2050. The NTB Province plans to reduce 3 million tonnes of CO2 equivalent through 3 programs: Green Tourism, Energy, and Industry. The benefit of the CBG plant in Lombok has the potential to reduce Green House Gas (GHG) emissions, replace LPG by 5,448 tons, provide employment opportunities, increase the use of renewable energy, and contribute to a circular economy while reducing waste.
The CBG project’s conception started in 2020 by PT Kaltimex Energy via its long-term cooperation contract with PT Gerbang NTB Emas. PT Gerbang NTB Emas will provide corncob feedstock and distribute CBG offering competitive selling prices compared to industrial LPG in the Lombok area. The ten tonnes per day CBG plant in the West Lombok Regency of NTB plans to start operations in the beginning of 2025, providing CBG as a substitute for LPG for industries along with Hotels, Restaurants, and Cafes.

About KALTIMEX Energy:
Incorporated in 1996 in Indonesia, Kaltimex was a Pioneer company to obtain The First IPP Licence in the private sector to operate a 23MW Power Plant for a Textile Company in Central Java. Since then it has its footprints in Singapore, Bangladesh, Philippines and Myanmar. Its business model remains in EPC, IPP and representing top class power companies like Dresser Rand (Siemens owned), MWM (Caterpillar owned), HTT, Viessmann Boilers, Wabio, Voltas and now OPRA Turbines. Kaltimex offers Total Power Solutions including co-generation and tri-generation. It has recently started to focus in Renewable Energy space like Waste to Energy (WTE), Waste to Liquid (WTL) and Bio-CNG. The Group Chairman and Founder of the group, Mr. K.K.Ralhan has set his eyes to take his group to Public in the next 3-4 years.
The objective of the seminar was to introduce PT. Kaltimex Energy as the official service partner of MWM in Indonesia. Founded in 1996, Jakarta-based Kaltimex was the first enterprise in the private sector to receive an IPP license for a 23-MW power plant for a large textile company in central Java.
The partnership between MWM and PT. Kaltimex Energy is not entirely new. For about 19 years, Kaltimex Energy Bangladesh (Pvt.) Ltd (KEBD) has been the authorized MWM distributor in Bangladesh and is the first certified MWM Distributor in Asia. So far, the company has installed gas engines with a total output of more than 750 MW throughout the country. In Indonesia, MWM gas engines with a total output of more than 428 MW installation thus far.
MWM Gas Engines Counteract Power Supply Bottlenecks in Indonesia
MWM Gas Engines Supply 28 MW In Riau, Indonesia:
In early 2016, 14 MWM TCG 2020 V20 gas engines were installed in the Indonesian province of Riau to counteract the power outages and energy bottlenecks that frequently occurred in the region. Each of the power gensets has a capacity of 2 MWel. A parallel operation is possible. In this way, decentralized power and heat energy generate regularly. Apart from ensuring reliable power supply, the energy generation reduces costs, as it uses more efficiently available resources, and the power generated by the distributed system delivers various new income opportunities.
A new year has come, and looking back one year on our journey, we have experienced many challenges and changes as a company. Kaltimex Energy is putting all-out efforts to develop Renewable Energy based power generation plants, especially from biogas and biomass.
With our vast experience in the Palm Oil industry in connection with supply & EPC contracts for Siemens – Dresser-Rand Turbine, we expand our reach with our partnership with Wabio- Germany for its proven Biogas Technology, to explore the possibilities to develop Biogas Power Plants from Palm Oil Mill waste across the country. The same is with biomass by partnering with GGIE for the pyrolysis technology for correctly identified projects. We choose pyrolysis because it is more environmentally friendly compared with incineration technology.
As a company, we try to give our best to our customers through the recruitment of highly skilled engineers from Indonesia and abroad, and we provide further training to increase their skills even more. We believe that human resources are one of the company’s assets to give our customers the best services. We also restructured several management posts to let us move even more aggressively towards achieving our goals.
Kaltimex Energy is proud to be appointed to represent Caterpillar-MWM gas engines in Indonesia. MWM is not new to Kaltimex Energy since we represent them in Bangladesh for almost 19 years now, having installed more than 600 MW so far in that country. We are excited to develop the well-known brand even more and bring our hands-on experiences with MWM in Indonesia.
