Initially, in 2017, the y's production capacity was limited to 300,000 tons annually. Recognizing the need for growth, Green Munay has focused on utilizing spare capacity by collaborating with third-party suppliers of crude oil and gas. These partnerships are essential for unlocking the refinery's full potential and enhancing stakeholder value.

In 2018, the refinery embarked on a large-scale modernization program, introducing a fully updated processing line with an annual capacity of 1.3 million tons. Key developments included:

• Testing and activation of the "Old Line," with a capacity of 1.3 million tons/year
• Reconstruction and enhancement of the "New Line"
• Modernization and accreditation of the on-site laboratory
• Overhaul and expansion of transportation infrastructure
• Execution of over 35 investment projects as part of a comprehensive modernization initiative

By 2019, the refinery further expanded its capabilities with the commissioning of an atmospheric residue vacuum distillation unit, enabling a processing capacity of 1.7 million tons annually and achieving an oil refining efficiency of 76%. On March 15, 2020, Green Munay launched its Integrated Processing Plant for Distilled Gasoline Fractions. This cutting-edge facility facilitated the production of Class 5 motor gasoline in compliance with TR TS 013/2013 and GOST R 51105-97 standards, enhancing its product range and quality. The investment in the second phase of Green Munay's development reached 40 billion Tenge, underscoring the company's commitment to innovation, efficiency, and sustainability in oil refining.
