The report which was made available to the Ghana News Agency on Thursday by the World Bank indicated that Africa lags behind the rest of the world when it comes to electricity, with just 35 per cent of the population with access to power and a generation capacity of only 100 GW.
According to the report those who do have power typically consume relatively little, face frequent outages and pay high prices.
It said transmission infrastructure was a crucial middle part of the electricity value chain.
It said alongside generation and distribution, improving and increasing transmission infrastructure was key to closing the access gap.
It noted that so far, transmission in Africa had been financed from public sources and new models of financing involving the private sector have received insufficient attention from policymakers or financiers.
The report said the “Linking up: Public-Private Partnerships in Power Transmission in Africa”, report examines private sector-led investments in transmission globally and how this approach is applicable in sub-Saharan Africa.
It said the private sector had participated successfully in transmission networks in many countries in Latin America and Asia, and this approach could be replicated.
“Private finance has supported the expansion of electricity transmission infrastructure in many regions of the world and the same can happen in Africa.
“To attract private sector investment, however, governments need to adopt policies supportive of this strategy and establish the right business, regulatory and legal environment to sustain investor interest,” said Riccardo Puliti, Senior Director and Head of Energy and Extractives Industries at the World Bank.
The report said estimates of annual investments required from 2015-2040 to expand the transmission network range from $3.2 billion to $4.3 billion.
It explained that these investments were critical to delivering cost-effective power to households and industries.
The report examined independent power transmission projects (IPTs) in five countries- Brazil, Chile, India, Peru and the Philippines, where major power sector reforms were undertaken to privatize the sector.
It said the use of privately financed transmission lines in Brazil, Chile, Peru and India, for example, collectively raised more than $24.5 billion of private investment between 1998 and 2015.
The pointed out that this resulted in close to 100,000 km of new transmission lines.
The study provides a set of recommendations for countries to adapt to specific local conditions and lists 10 steps to get there, including the right legal and regulatory framework.
Others are new models for concessional lending, competitive tender processes, adequate revenue flow and credit enhancement for projects, or tailored IPT projects to attract international investors, to name a few.
