Success Stories
Master Changan Motors Company Limited (MCML)
Master Changan Motors Company Limited (MCML) has successfully completed its 2.5MW solar power project at its manufacturing site in Port Qasim, Karachi, in collaboration with Orient Energy Systems. The 2.5MW solar facility now powers MCML's operations and has resulted in a reduction of 3.5 million metric tonnes of carbon emissions annually. This makes Changan cars some of the greenest on the Pakistani market.This successful partnership further cements Orient Energy Systems as a leader in delivering sustainable energy solutions, contributing to Pakistan's green energy transition and positioning Master Changan Motors as a leader in eco-friendly automotive manufacturing.
Lucky Cement Limited
The 31 MW solar project at Lucky Cement Limited’s Karachi plant involved overcoming significant design and construction challenges, including the integration of a microgrid control system for both current and future generation sources. The system ensures a constant supply of cost-effective energy while maintaining reliability. The project led to a conservation of approximately 3.5 gigawatt-hours (GWh) of energy. OES’s comprehensive in-house design and construction expertise, supported by licensed software and robust quality control processes, were key to the project's success.
Mian Nazir Sons Industries
Orient Energy Systems (Pvt.) Ltd. has commissioned a 1 MWp solar-powered system at Mian Nazir Sons Industries, reducing their reliance on fossil fuels for energy generation. OES also conducted a grid study and will manage the system's operation and maintenance for the next two years. Mian Nazir Sons Industries, a pioneer in manufacturing polypropylene products in Pakistan, has partnered with OES during their expansion and modernization phase to meet energy needs.
