PPI investment in energy in 2017 marked a 11-percent increase over 2016 levels. In 2017, investments in energy stood at US$51.9 billion across 203 projects, compared to US$46.8 billion across 183 projects in 2016

In 2017, PPI transport investments almost doubled, and now accounts for a third of total PPI investments. US$36.5 billion was invested in 66 transport projects in 2017, compared to US$18.9 billion invested in 2016. Although the energy sector continued to be the predominant sector, transport investments accounted for a higher proportion of overall investments in 2017 compared to previous years—transport PPI investments accounted for more than a third (39 percent) of total investments in 2017 across all four sectors (energy, water, transport and information and communication technologies (ICT)), compared to only about a quarter (24 percent) in 2016

Declining water and sewerage investments in 2017. The 2017 sectoral investment level at US$1.9 billion across 30 projects, not only represents a slight decline (seven percent) com¬pared to the 2016 levels but is also 55 percent lower than the five-year average of US$4.2 bil¬lion. In 2017, water and sewerage was the only sector to report a decline in investment levels

Considerably higher investment in ICT-backbone1 in 2017. In 2017, PPI investment in ICT-backbone projects reached US$3.0 billion across six projects. This is six times the 2016 investment level of US$462 million and twice the previous 10-year average of US$1.3 billion. The PPI investment commitment in the ICT-backbone sector in 2017 accounted for 3.2 percent of the total PPI investment, compared to 1.3 percent over the past 10 years.

Total investment in energy projects with private participation in 2015 in low- and middle-income countries was US$37.6 billion, 50 percent below the five-year average of US$74.7 billion.

Total investment in transport projects with private participation in emerging countries in 2015 was US$69.9 billion, 53 percent above the five-year average of US$45.6 billion.

In 2015, total investment in water projects in developing countries was US$4.1 billion, 8% higher than the five-year average of US$3.8 billion (2010-2014).

The data indicates that the number of disruptions for projects in pipeline peaked in April and has since been decreasing. For projects already under construction, the number of projects facing disruptions peaked in May and has since been decreasing as well.

Infrastructure development is a critical factor for a country’s long-term growth and economic development.Well-designed and efficiently implemented investments in infrastructure can promote economic growth and improve access to basic services that boost quality of life.

2017 was a stellar year for PPI investments in IDA countries. Private participation in infrastructure (PPI) investments1 in IDA countries totaled US$7.9 billion across 35 projects in 17 countries in 2017, compared to US$2.9 billion in 2016 across 18 projects in 10 countries. IDA countries accounted for 8.5 percent of total PPI investment in 2017, up from 4.3 percent in 2016.

A growing body of quantitative research on public-private partnership (PPP)

performance, particularly for long-term infrastructure contracts, attends to factors

that influence the level of investments in PPP and PPP performance over time.

After 2010, favorable government policies led to a surge of low-carbon projects. The percentage of low-carbon projects receiving government support grew from 3% before 2010 to 51% afterwards. The distribution of new project investments shifted in favor of low-carbon—prior to 2010, distribution was even, but after 2010, the number of new low-carbon PPI projects (1,915) was more than double that of conventional ones (815).

Over 85 publications draw their analyses from the PPI Database and these have been categorized by sector, region, and themes. With the click of a button, a vast resource of information on infrastructure investments is now accessible to all.

Access the data on how PPPs in low and middle income countries were financed in 2015, with information on public and private financing withbreakdowns by region and sector. 

During 2011-2015, PPI investments amounted to $27 billion across 143 projects concentrated in 24 out of the 56 IDA countries

Private investment in infrastructure in IDA countries from 2009 to 2014 totaled US$73 billion.
