Hybrid Renewable Power Storage System for Mobile Network Operators

Technology / Service Summary

Renewable Energy solution to be used by Solar PV generation or Wind generation. It is utilized by combination with abovementioned Natural energy, Diesel Generator, On-Grid and Battery Storage.

Purpose

-

Feature

This is a proposal on Hybrid Renewable Power Storage System, mainly for use by Base Tower Stations of Mobile Network Operators. The system can also be utilized as Hybrid Renewable Power Storage System for off-grid areas and mini-grids for community in rural area. It enables integrated operation and management by controlling output power, remaining charged power capacity of battery storage, generated power by solar panel or wind, power supply from grid, generated power from diesel generators, remaining amount of fuel for generators, etc., all necessary calculated power load. The system can propose optimal use of power load by predicting a) future required power load based on actual used power load in the past, and b) generated power from solar panel based on meteorological data of past several decades.

Accomplishments

NEC has already installed Nigeria, South Africa, Kenya and Tanzania.
Before and after comparison of diesel fuel consumption reduced 30 to 40 % in actual cases (depending on actual use of power load by clients). This system can be used in hybrid by combination with conventional and newly installed generators, solar panels, grids and power storage battery system. We will offer control equipment with full turn-key condition.
NEC has already conducted trial of 770 Ah Hybrid Renewable Power Storage System in Kenya, from June 13, 2019 to October 30, 2019. Reduced more than 50% of cost after installation of Hybrid Renewable Power Storage System, including diesel fuel and transportation cost. These system were installed and in operation for clients in Nigeria since 2017, in South Africa since 2018 and in Tanzania since 2020. And to be installed over 90 units of Hybrid Renewable Power Storage System in 2021 in Kenyan clients to whom NEC has conducted POC in 2019 as abovementioned.
