The Climate Report 2017/18 - Page 4

The International Hydropower Association monitors global trends and
development in the sector, and manages a database of the world’s
hydropower stations. Each year, the Hydropower Status Report provides
a comprehensive overview of recent developments.
In 2016, hydropower development continued a steady growth trend,
driven by a demand for reliable, clean and affordable power as countries
seek to meet the carbon reduction goals set out in the Paris Agreement.
Key trends and noteworthy developments
• An estimated 31.5 GW of
hydropower capacity was put
into operation, including
pumped storage, bringing the
world’s total installed capacity
to 1,246 GW
• 6.4 GW of pumped storage capacity
came online, nearly twice the
amount installed in 2015
• Total hydropower generation for the
year is estimated at 4,102 TWh, the
greatest ever contribution from a
renewable source
• China once again led the market for
new development, adding 11.7 GW
of new capacity, including 3.7 GW of
pumped storage
• Other countries leading in new
deployments include Ecuador
(2 GW), Ethiopia (1.5 GW), South Africa
(1.3 GW), Vietnam (1.1 GW), Peru
(1 GW) and Switzerland (1 GW).
Initiatives are being established to
manage the risk profile of hydropower
With an ever-increasing focus on ensuring
projects are built in the right way and in
the right place, momentum is building for
the establishment of a support facility for
hydropower project preparation. Such a
facility would optimise private sector
engagement by managing a revolving
fund to support the selection of the most
appropriate project type and location
according to the local context.
This approach could help ensure projects
are built to the highest environmental
standards and are compatible with the
goals of the Paris Agreement, and would
allow developers access to the growing
green bond market, which nearly
doubled in value in 2016, reaching a
record USD 81 billion in issuances.
Renewables are working together to
support grid stability
Innovative projects coupling renewables
technologies are providing firm, stable
power to the grid, while increasing
efficiencies and creating net benefits.
Floating photovoltaics on hydro reservoirs
are under construction in all regions.
Taking advantage of existing infrastructure,
“floatovoltaics” also have increased
efficiencies due to greater cooling.
Also, floating PV panels on hydropower
reservoirs can help reduce water losses
due to evaporation. Pilot projects began
in Brazil, while India announced plans for
600 MW project on the Koyna reservoir.
The USA began operations at the world’s
first geothermal-hydropower hybrid
project, where a hydropower turbine was
added to the injection well, resulting in
reduced operational costs and well safety.
The role of pumped storage is serving
global energy storage requirements
Remaining the only form of electricity
storage available on a large scale and at a
competitive cost, pumped storage systems
are continuing to grow, adding over 6 GW
in 2016. Pumped storage technologies are
also evolving with our changing energy
systems. An innovative wind-hydro hybrid
pumped storage system began
construction at the German Naturspeicher
project. Vessels at the base of the wind
turbines themselves act as upper reservoirs
of a pumped storage system. Wind turbine
heights are increased, harnessing stronger
winds, and the pumped-storage
technology regulates frequency variations
from fluctuations in wind. Meanwhile,
pumped-storage projects are being
developed for small-grid systems in Hawaii
and on the island of Gran Canaria.
