Huawei Kenya has its sights on the light manufacturing industries with a new energy intervention designed to cut electricity costs and stabilize energy usage. Light industry refers to a range of industrial sub-sectors including food processing, textiles and machinery that have less demanding energy needs compared to heavy industries such as steelmaking and chemical production plants.
Speaking during the Fusion Solar Partner Summit in Nairobi, Charles Yang, Huawei Digital Power President for Global Marketing and Sales Services, said that the firm had developed the Luna 200 2.0 MWH Smart String Energy Storage System (ESS) that incorporates fire, electrical, structural, and artificial-intelligence-based safety features in response to a strong need from light manufacturing industries. An Energy storage system (ESS) is a device that stores electrical energy. It can be used to power electrical grids, support the reliability of the grid, and store excess electricity for later use.
“There is a global trend towards batteries for businesses and national grids, caused by reduced battery prices, increased fuel prices and the drive for decarbonization. Indeed, the more solar energy and wind energy we use, the greater the need for reliable batteries,” said Yang. He noted that Huawei has named the new energy storage products “Smart String Energy Storage System” because they have battery optimizers at the pack level that delivers up to 15% more usable electricity, contains enhanced safety features, has better monitoring and promises decreased downtime.
The new solution is suitable for Kenya’s light manufacturing industries, which have in recent years registered remarkable growth in energy needs. Between 2010 and 2015, the number of Small and Medium Enterprises (SMEs) connected to the national electricity grid increased by over 60%.
Many light manufacturers are shifting to solar energy as grid electricity costs escalate and supply remains intermittent. Starting at a modest 3 MW in 2012, Kenya’s solar capacity increased to 7 MW in 2013 and further surged to 16 MW in 2014. The following years showed a steady upward trend to reach 30 MW in 2015 and 31 MW in 2016. The capacity in 2017 was 38 MW, then rose to 105 MW in 2018. From 2019 to 2020, the capacity remained relatively stable at around 106 MW. However, in 2021, it substantially increased to 147 MW, then significant rose to 169.2 MW by 2022.
“Luna 200 offers up to 50% longer life span as the independent air conditioners keep the temperature in the cabinet within 3 degrees of 25 Celsius. Temperature is a big contributor to a shorter battery lifespan,” said Yang.
It also provides an uninterruptable power supply to industries, including manufacturing and automotive production. Huawei’s solution is designed with multiple layers of safety protection. Furthermore, fire safety is critical with the incorporation of humidity, temperature, and smoke sensors that detect a flammable gas and automatically exhaust it. A substance is then released to extinguish any potential fire.
“At a large-scale manufacturing plant, for example, a power shutdown or breakdown in the supply of monitoring/control information can have a disastrous effect on productivity which ultimately could impact on a business’ bottom line,” explained Yang. Thus, adopting energy storage systems is crucial in the transition to sustainable energy sources. Energy storage solutions represent a promising advancement since they store energy during off-peak hours to be later used when needed.
