According to the IEA's 2019 World Energy Investment Report, hydropower investment in 2018 rose slightly from 2017, to just over $50 billion
.
For the purposes of this report, hydropower includes pumped storage
.
After three years of recession, global energy investment stabilized at more than
$1.
8 trillion in 2018, according to the report.
More spending on oil, gas and coal supplies was offset
by lower spending on fossil-fuel-based power generation and renewables.
Energy efficiency efficiency expenditures are largely unchanged
.
Electricity still attracted most investment, overtaking oil and gas
for the third year in a row.
On a cost-adjusted basis, investment activity in solar PV and wind grew the strongest, benefiting from lower costs and increased deployment, especially compared to five years ago, although this trend was suspended
in 2018.
The IEA said cost-adjusted investment was less pronounced in hydropower, the rate of increase had slowed, and a larger share of development work was in higher-cost areas
.
For hydropower, costs are site-specific, and China's share of deployment has declined over the past decade, raising the global weighted average
.
In different regions, costs do not change much
.
The construction time for new capacity has increased, reflecting the typically large plant size and land and water management requirements
that can add complexity to the project.
In addition, the main sources of large dispatchable electricity, including coal, natural gas, nuclear and hydropower, final investment decisions or FIDs fell by a quarter in 2018 to 90 GW.
Hydropower projects accounted for the main share
of hydropower projects that first adopted FID in 2018.
