The “2.5MWp PV + 1.5MW/2.5MWh E Storage System+ 3MW Diesel Generating” off-grid microgrid solution for Camp B9, Iraq, provided by Kehua, has been successfully implemented. It is also the first benchmark project of Iraq’s Ministry of Oil and Ministry of Electricity. This photovoltaic storage power plant is the first in Iraq. It attracts a lot of interest from the industry as well as joint concern from the Ministry of Oil and Ministry of Electricity.
Basra, in southern Iraq, is the location of the PV+ESS+DG project to Camp B9. The entire off-grid power supply system consists of 2.5MW PV, 1.5MW/2.5MWh energy storage, and 3 diesel generators total. This maximizes energy utilization efficiency through multi energy complementing and intelligent control.
The project uses “PV + energy storage system+ diesel generator + medium voltage substation + energy management system” to ensure the long-term efficiency and stability of the oil-area electricity grid. Due to the harsh application scenarios, the reliability of key equipment is also required. Kehua’s PV inverters, PCS products, have been extensively used in the PV+ESS scenario. They offer many benefits, including high safety, high efficiency, and high protection. The EMS operation logic, which is tailored to this project, monitors all aspects of the power plant equipment to ensure safe and stable operation and delivers clean electricity to oil areas continuously around the clock.
The team faced many challenges, including windy and sandy construction environments, stringent approvals of oil areas, and strict quality requirements. They were able to create the Kehua speed, which allowed construction to begin and commissioning in half a year from the date the project was awarded in December 2021, until the time of commissioning.
The project will provide approximately 3GWh of green power to the locality annually. This is equivalent to saving 1,200 tonnes of standard coal annually. It also reduces the emission of several air pollutants such as 90 tons sulfur dioxide, 2,991 tons carbon dioxide and 45 tons nitrogen oxides. This will help transform Iraq’s energy system.
