Global Electricity Distribution Sector: Sales of Top 20 DSOs [free access]

February 12, 2021

The electricity distribution market structure across the world is heterogeneous with a high level of concentration in some countries and a highly fragmented structure in others. Electricity distribution is still largely under the control of state-owned utilities or local municipalities in most regions. That said, in some markets like the US, some EU countries, Chile and the Philippines, the electricity distribution sector is dominated by private players.

 

Global Transmission Research, in its recently released ‘Global Electricity DSO Profiles Report 2020’, has analysed the operations and future plans of 250 distribution system operators (DSOs) across six regions. These 250 DSOs delivered 14,820 TWh of electricity during 2019. The distribution network of these DSOs comprised over 36.5 million km in the 74 countries.

 

Among the top 20 DSOs, utilities from China, Russia, South Korea, France and Saudi Arabia accounted for close to 75 per cent of electricity sales with over 550 million customers in 2019. China’s State Grid Corporation of China (SGCC) accounted for the largest share of sales, of 46 per cent, followed by China Southern Power Grid (CSG) at 11 per cent, Russia’s PJSC Rosseti at 6 per cent and South Korea’s Korea Electric Power Corporation (KEPCO) at 5 per cent.

 

 

China’s CSG and SGCC witnessed the highest growth rate in electricity sales, which grew at a CAGR of 7.1 per cent and 5.1 per cent respectively during 2014-19, followed by Indonesia’s Perusahaan Listrik Negara (PLN) and Egypt’s Egyptian Electricity Holding Company (EEHC) at a CAGR of 4.3 per cent and 3.6 per cent, respectively.
