When people talk about electric power in China, one name that often comes up is Shaanxi, for this is the province that harbors the most extensive power distribution network company in China and nurtures the most dynamic electric power market of the country.
With its headquarters in the Chinese city of Xi’, Shaanxi Regional Electric Power Group is a large-scale electric power company which supplies power to more than 1,000 townships in 70 counties and districts in 9 municipalities of Shaanxi province.
With 6.38 million power customers, SPG proudly covers 76 percent of the provincial territory, or an area of 142,500 square kilometers, and provides electric power service to more than 20 million people in its catchment area.
In Ghana, SPG works with its strategic partner BXC Ghana, a partnership which has seen the Electricity Company of Ghana (ECG) received over US$200 million in investment to boost its infrastructure to ultimate make the local power distributor more efficient.
The two have been instrumental with the quest to turnaround the fortunes of the local power distributor via the ECG Private Sector Participation programme which seeks to bring ECG to world-class standards.

SPG has built an automatic smart meter maintenance system and is popularizing the application of diversified payment methods, smart meters, Unmanned Aerial Vehicle line-patrolling, and line inspection robots.
Modern grid dispatch hall
SPG strides towards an IT-based and intelligent group by putting in place a four-level information ‘highway’ connecting the provincial, municipal, county, and station levels through dispatching and management networks which make grid management increasingly data-based, standardized, and fine-grained.
SPG has been actively involved in exchanges and cooperation with the EDF Group of France, Tokyo Electric Power Company (TEPCO), Singapore Power Group (SPGS), and has built a technology sharing platform with local tertiary institutions such as Tsinghua University, Xi’an Jiaotong University, and North China Electric Power University.
Delivering value to the customer
Devoted to solving the “last mile” of the power distribution network, in 2017, SPG increased the urban and rural electricity reliability to 99.97 percent and 99.85 percent respectively.
SPG earnestly provides universalized service and fulfills its social responsibility. It has implemented projects such as “Harmonious Electricity Entering Households”, “Photovoltaic for the Poor” and rural network renovation & upgrading and has reached the target of providing every household with access to electricity in the province in 2010.
SPG has formed a modern corporate governance structure consisting of the board of directors, the board of supervisors, shareholders and management. Building blocks of SPG’s business involve power supply, power generation, auxiliary power services, and multi-business, having about 24,000 employees.

It should encourage deep integration of the power distribution network with the Internet and coordinated development of the power grid and new energy to allow flexible connection and efficient use of diversified load such as that of new-energy-powered or electric vehicles.
In the context of deepening Africa-China and Ghana-China ties, SPG stands ready to forge ahead with partners such as BXC Ghana to make investments and contributions to the development of power distribution network in Ghana by jointly building a new type of modern power distribution network in West Africa.
