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 also been engaged in building a development community with openness and inclusiveness by actively implementing big data strategies and information technology, leading the strategic alliance of key equipment technology innovation of intelligent distribution grid.
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.
The group invests in finance, healthcare, railways and other areas. SPG’s electricity sales and maximum load both register an average annual growth rate of 14 percent, and the average increase of annual per capita electricity consumption reached 13 percent.

Guided by the vision of green, sustainable, and quality-based development, SPG answers the global call for developing alternative energy sources and facilitating energy transition by scaling up clean energy development, evidenced by registering a 16.4 percent increase in new energy generated electricity within SPG’s network.
Three of SPG’s hydropower plants have won support from the UN Global Environment Facility, and four hydropower plants have been listed as China’s first batch of Green Small Hydropower Projects, aiming to create a friendly, shared and green power grid.
The future
SPG’s latest development plan sets the goal to invest close to US$4.8 billion by 2020 — to build a modern power distribution network consisting of a range of projects including the building and renovation of eighty-six 110kV substations with 5,128km of associated lines, and 22,542km of 10kV lines, with the rate of Coverage of Distribution Automation and smart meters amounting to 100%.
The new network is to feature a world-class network and service system with coordinated urban-rural development, safety and reliability, advanced technology and eco-friendliness.

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.
