• Capex on electricity transmission: Key growth drivers and challenges [free access]

  October 8, 2021
  In the developing economies of Asia, Africa and the Middle East, a critical driver for investment in the transmission sector is the need to meet the growing demand for electricity and focus on improving electricity access and achieving 100 per cent electrification. In Latin America and Asia, governments are focusing on privatisation to fast-track grid investment. In geographically large countries such as China and India, high voltage direct current (HVDC) is emerging as the preferred technology for long-distance power networks. Meanwhile, developed countries are investing in improving their ageing power infrastructure with advanced technologies to meet the dynamic nature of supply and demand in the future.
