At the recent SNEC event, Peng Jianhua, President of Site Power Facility at Huawei Digital Power Technologies, released the full series of comprehensive off-grid fuel removal power solutions, iPowerCube, to a global audience. Serving as an inclusive power supply in all scenarios, the solutions provide cost-effective, green and reliable power for people’s livelihoods and industrial production in off-grid and unreliable grid areas, helping bridge the energy divide.
Mr. Peng said that electricity supplies are unbalanced around the world. Currently, about 800 million people are living in mountainous areas, islands, deserts and other regions that have no access to grid power. In these regions, a huge number of diesel generators (D.G.s) are used for power generation. There are more than 50 million D.G.s worldwide. D.G. cost is several times higher than that of grid power and D.G.s are highly polluting. 1 kg of diesel fuel will generate 3.18 kg of carbon emissions. In addition, D.G.s are costly, difficult to maintain and noisy, which seriously affects the normal life of residents and restricts local economic development. With advances in technology, the cost of photovoltaic (PV) and energy storage decreases. Replacing D.G.s with solar energy to achieve low-cost and green inclusive power supply becomes a reality.
Full series of comprehensive off-grid fuel removal power solution, iPowerCube, provides green and inclusive power supply in all scenarios of people’s livelihood and industrial production.
iPowerCube integrates power electronics technologies (such as watts, heat and energy storage) and digital technologies (such as cloud, AI, and connection) to streamline energy and information flows. It fully utilises PV and energy storage to replace D.G.s, meeting inclusive power supply requirements of large, medium, and small-scale power consumption scenarios. Compared with traditional solutions, iPowerCube features simpler reconstruction, faster deployment, and lower cost, making it more applicable to areas with no or poor grid power.
Large-scale off-grid fuel removal solution iPowerCube-P:
Provides megawatt-level power supply capability and applies to industrial production scenarios such as mines, factories and campuses, as well as livelihood scenarios such as large villages, islands and resorts. Compared with the traditional AC coupling solution, the iPowerCube-P uses a DC coupling architecture, which reduces the number of energy conversion times, improves efficiency, reduces investment, and lowers LCOE.
In Cameroon, over 25 MW of PV plants and 60 MWh of energy storage systems adopt the Huawei off-grid solution, powering 350 remote villages and benefiting about 50,000 households with approximately 300,000 residents.
Medium-scale off-grid fuel removal solution iPowerCube-S:
Provides 100 kW-level power supply capability and applies to livelihood scenarios such as small villages and islands as well as industrial production scenarios such as oil and gas wells, checkpoints and transportation stations. Compared with the traditional split-type solution, Huawei iPowerCube-S adopts pre-integration and does not require distribution network reconstruction, which shortens the deployment period and reduces investment.
In Zhuhai, Huawei’s iPowerCube-S solution is used to replace the original D.G. and supply power to the professional equipment and living facilities of the ship navigation station on the island. In this way, the D.G. is not required. The LCOE is reduced by 60%, the D.G.-related cost is cut by CNY220,000 each year, and 25 tons of carbon emissions are avoided.
Small-scale off-grid fuel removal solution iPowerCube-M:
Provides 10 kW-level power supply capability and applies to residential scenarios (such as apartments with no/poor mains power supply and rural villas) and industrial and commercial scenarios (such as shops, restaurants, and business outlets). Compared with the traditional solution with combined gasoline generator and batteries, the Huawei iPowerCube-M solution features more flexible deployment, ultra-quiet design, higher reliability, and lower LCOE.
In Inner Mongolia, the iPowerCube-M uses efficient PV + energy storage to provide 24/7 reliable power for the daily life and operations of herdsmen.
