INTELLIGENT BRANDS // Green Technology Huawei’s Microgrid Solar Solution powers rural Cameroon C ameroon’s electricity development had been quite slow; the areas covered by electrification were only 28% of the country’s territory, and 80% of the power was concentrated in the capital of Yaoundé as well as the economic port, Douala. Unfortunately, only 56.8% of the population had access to electricity; the national population was just under 24 million (by 2016), which meant more than 40% of the population lived without power. About 80% of the rural population still used wood as their primary life energy. According to Cameroon national power development planning, the current investments into hydropower, thermal power stations, and national grid construction was quite extensive, yet development could not meet the power demands for the vast “Huawei implemented a natural cooling design according to Cameroon’s climate situation, which greatly reduced its system power consumption.” www.intelligentcio.com number of country’s residents in the short-term. Cameroon urgently wanted to realise ‘rural electrification’ in order to: improve the electricity access rate in rural areas, improve the living standards of its citizens, promote the development and utilisation of local resources, and further drive the development of education, medical care, communications, manufacturing and other industries. Solution Huawei – with strong technical capabilities in the field of photovoltaic inverters, along with continuous technological innovations and long-term accumulated experience in the energy storage field – provided its Microgrid Solar Solution. This advanced solution contains an energy storage system and supports diesel generator access, with the goal to provide reliable power for areas without grids or access to power. Huawei provides standardised and customised configurations according to customers’ requirements and load conditions. The solution supports PV- installed capacity between 30 kW to 300 kW for now, and can expand to a MW-level installed capacity by 2018. With advanced Maximum Power Point Tracker (MPPT) technology, high efficiency inverter, advanced charging and discharging management technologies, the overall system power generation capacity is 3% more than other solutions which also helps customers achieve more benefits. The energy storage system utilises battery technology that withstands high temperatures and still provides good performance in these environments. Huawei implemented a natural cooling design according to Cameroon’s climate situation, which greatly reduced its system power consumption. Meters were installed in the users’ homes which can recharge according to their electricity demands. The background management system processes the automated electricity metering by recording the sales details and usage information, and helps to simplify the management of the operations department. Results Huawei Microgrid Solar Solution now helps 166 villages (and over 120,000 people) benefit from electricity in Cameroon; the average annual power generation is now more than 17 million kWh, the rural electricity coverage rate increased from 18% to 20%. The project greatly enhanced local residents’ living standards, education and medical conditions, and improved basic conditions for the development of agriculture, communications, and manufacturing industries. The project has been widely recognised by local citizens, and the government also receives more political support from its people. With its simple, efficient, and reliable features, Huawei Microgrid Solar Solutions are constantly winning customers’ trust, providing power in remote and isolated areas previously not able to receive energy, and creating much greater value for society. n INTELLIGENTCIO 59
