An estimated 40 GW of new hydropower capacity was commissioned in 2013, increasing total global capacity by about 4% to approximately 1,000 GW.i 1 Global hydropower generation, which varies each year with hydrological conditions, was estimated at 3,750 TWh in 2013.2 The top countries for hydropower capacity and generation remained China (260 GW/905 TWh), Brazil (85.7 GW/415 TWh), the United States (78.4 GW/269 TWh), Canada (76.2 GW/388 TWh)ii, Russia (46.7 GW/174.7 TWh), India (43.7 GW/estimated 143 TWh), and Norway(29.3 GW/129 TWh), together accounting for 62% of global installed capacity.3 (See Figure 10 and Reference Table R6.) An estimated 2 GWof pumped storage capacity was added in 2013, bringing the global total to 135-140 GW.iii 4

The lion'sshare of all new capacity in 2013was installed byChina, with significant additions by Turkey, Brazil, Vietnam, India, and Russia.5 (See Figure 11.) China commissioned a record 29 GW, for a total of 260 GW of hydropower capacity at year's end. Among significant milestones for China in 2013 was the start of operations at the Xiluodu plant in July, with 9.2 GW of capacity generating electricity by year's end. Xiluodu is expected to reach full capacity (13.86 GW) by mid-2014, when it will rank as the third largest hydropower plant in the world, behind China's Three Gorges and Brazil's Itaipu.6

The 6.4 GW Xiangjiaba plant, also on the Jinsha River, will be China's third largest hydropower plant when completed in 2015. By mid-2013, four 800 MW turbine-generators—reported to be the world's largest hydroelectric units—had been installed at this facility.7 By the country's own accounts, investment in China's hydropower infrastructure exceeded USD 20 billion (CNY 124.6 billion) for the year.8 Chinese banks and industry have also pursued hydropower projects overseas, with a notable presence in Africa and Southeast Asia.9

Turkey continues a rapid expansion in its hydropower sector to meet significant growth in national electricity demand. After adding about 2 GW in 2012, Turkey brought another 2.9 GW on line in 2013, for a total of 22.5 GW, placing Turkey among the top 10 countries for hydropower capacity.10 Turkey's hydropower capacity generated 59.2 TWh in 2013.11

Brazil added at least 1.53 GW and possibly as much as 2 GW in 2013, including 264 MW of small-scale hydro (<30 MW) capacity, for a year-end total of at least 85.7 GW.12 The 334 MW Simplicio plant, completed mid-year, is considered notable for its high power output relative to reservoir area.13 In addition, two run-of-river plants, both part of the Madera River complex, advanced during 2013. The first of fifty 75 MW turbines at the Jirau plant (3.75 GW) became operational and, by year's end, the Santo Antonio plant (3.6 GW) had 22 turbines in operation. Santo Antonio was expanded from 44 to 50 bulb-type turbines to improve operational flexibility in a river characterised by great flow variability.14 These two plants exemplify a trend in Brazil away from larger reservoirs and toward run-of-river projects, driven in part by the objective of reducing land use in sensitive areas and improving project sustainability.15 The Belo Monte has also been modified to address sustainability concerns. To reduce flooded area, its reservoir capacity will be smaller than originally planned, with a firm year-round capacity of only 4.5 GW; however, it will retain a peak seasonal capability of 11.2 GW, second in Brazil only to the 14 GW Itaipu plant.16 Another significant project under way in 2013 was the Teles Pires project (1,820 MW by 2015), which overcame charges of having neglected obligatory social impact studies.17

Vietnam has developed its hydropower resources at a rapid pace in recent years. It appears that at least 1.3 GW of capacity was added in 2013, for a total of 14.2 GW installed.18 However, following earthquake damage at the Song Tranh 2 dam, as well as concerns about adverse social impacts associated with resettlements, local and central governments are taking a more measured approach to the development of additional hydropower facilities, calling for evaluations of safety at existing dams and curtailment of new hydropower development.19

Significant capacity was also added in India and Russia during 2013. India installed 0.8 GW of hydropower capacity in 2013, of which nearly 0.6 GW was in installations larger than 25 MW.20 In late 2013, the Permanent Court of Arbitration in The Hague gave a green light to India's 330 MW Kishenganga plant, having determined that it would qualify as a run-of-river plant and thus not violate terms of the 1960 Indus Waters Treaty with Pakistan.21 Russia may have installed as much as 3.2 GW of new turbine-generators during the year, but the net increase in installed capacity amounted to only 0.7 GW, with rehabilitation of existing facilities presumably accounting for the difference.22

Africa saw at least two projects completed during the year. Ghana's second largest hydropower station, the 400 MW Bui plant, and Gabon's 160 MW Grand Poubara plant both became operational in late 2013.23 These plants were built by Sinohydro (China) and financed largely by China Exim Bank.24 Meanwhile, rehabilitation started on the 350 MW Inga 1, which entered service in the early 1970s.25 There are many ageing facilities in Africa that operate below original rated power and now require refurbishment, such as ongoing work on the Kainji and Jebba plants in Nigeria.26

There is growing support for future development in Africa, and many impending new hydropower sites exist on the continent. During 2013, Alstom (France) was awarded a contract for eight 375 MW Francis turbines at the Grand Renaissance Dam in Ethiopia, a project that will total 6 GW and has raised tensions with downstream Sudan and Egypt over water rights.27 The World Bank announced funding for the Regional Rusumo Falls plant (80 MW) under its new Great Lakes Regional Initiative, with the primary aim of increasing power supply for the people of Tanzania, Rwanda, and Burundi.28 Also in 2013, a new purchase agreement between South Africa and Congo prompted an announcement that construction of the Inga 3 project (4.8 GW) on the Congo River would begin by late 2015.29 This project is the long-anticipated next step towards what might become the largest hydropower complex in the world, at about 40 GW.30

i - The GSR 2013 reported a global total of 990 GW at the end of 2012, but that figure has been revised downward by 30 GW. For additional information, see Methodological Notes, page 142, and Endnote 1 of this section. Unless otherwise specified, all capacity numbers exclude pure pumped storage capacity if possible.

ii - Despite slightly lower total capacity, Canada's baseloaded output exceeds the more load-following output in the United States.

iii - Pumped hydro plants are not energy sources but means of energy storage. As such, they involve conversion losses and are powered by renewable or non-renewable electricity. Pumped storage can play an important role as balancing power, in particular for variable renewable resources. Some conventional hydropower plants also have pumping capability.

Pumped storage capacity expanded during 2013 in China and Europe. China added 1.2 GW of pure pumped storage capacity for a total of 21.5 GW.31 In addition, the last phase of Spain's La Muela pumped storage complex was inaugurated, counting 2 GW of capacity at year's end.32 La Muela was conceived as part of a backbone for Spain's extensive variable renewable power capacity.33 It has been argued that further expansion of storage capacity, which is considered increasingly important as shares of variable wind and solar power rise, will require that markets place greater monetary value on facilities that provide storage and ancillary services.34 Variable resources have helped to moderate peak system loads and thus peak power prices, but in doing so, they may also have upset the traditional business model for pumped storage. Subsequently, power markets may need to evolve to reflect these changing circumstances.35

Looking ahead, plans for future hydro pumped storage projects in Europe are said to be hampered by onerous market conditions such as two-way transmission fees (for both generation and pumping).36 On the other hand, Germany appears to have addressed such concerns to some extent and has expanded exemptions for pumped storage facilities from grid charges under certain conditions.37 However, pumped storage has always had relevance outside the context of variable resources. For instance, Japan's 26 GW of pumped storage capacity (in addition to 22 GW of conventional hydropower capacity), was conceived primarily as load-following support to baseload nuclear power; going forward, it will be used increasingly to balance variable resources.38

Any shortage of transmission capacity and interconnection can constrain both access to hydropower resources and their potential for balancing variable renewable resources.39 Trans-border interconnections conceived primarily to facilitate flow of hydropower include the Eastern Electricity Highway between Ethiopia and Kenya, which was launched in 2013 and could carry up to 2 GW upon completion, planned for 2018.40 The 1,800 kilometre Central American SIEPACi interconnection was largely completed in 2013, improving transmission capacity and reliability across the region. Despite its modest scale (300 MW capacity), it is regarded as an opportunity to increase implementation of large and small renewable energy projects, including hydropower.41 In North America, at least two nterconnection projects were under consideration in 2013 to bring Canadian hydropower to U.S. markets: the controversial Northern Pass project that would supply 1,200 MW of baseload power from HydroQuebec (Canada) to New England, and an agreement to complement a North Dakota wind farm with 250 MW of balancing supply from Manitoba Hydro (Canada).42

In 2013, the World Bank Group announced that it remains committed to environmentally and sociallysustainable hydropower projects of all sizes and types, highlighting hydropower's role in climate change mitigation, but also its vulnerability to any climate-related water scarcity.43 Uncertainty regarding the future impact of climate change on hydropower and other renewable energy technologies—including energy production, policies, and markets—prompted Norway's Statkraft to launch an R&D programme on the topic.44


Hydropower capacity additions in the five-year period end-2008 to 2013 were significantly greater than during the previous five years.45 However, despite a significant jump in new capacity in 2013, the intake of new orders for some major companies declined relative to 2012.

For example, Andritz Hydro (Austria) reported that both sales and new orders were down from very high levels in previous years, although project activity was deemed satisfactory for small-scale hydropower.46 Neworders were down forVoith Hydro (Germany) as well. Sales increased by 6% in the 2012-13 fiscal year, but the market was below Voith's expectations. However, the company noted that the market for plant modernisation is a major driver of new orders in many regions.47 Voith also announced advances in the area of very large generating units (such as the 784 MW turbines supplied to the Xiluodu plant in China), as well as small in-stream and low-head units, such as its prototype StreamDiver.48

Alstom (France) noted a slowdown in demand for new capacity but growing demand for rehabilitation of the ageing stock of existing plants.49 Aiming to strengthen its capacity in China, Alstom inaugurated its upgraded hydropower industrial site in Tianjin, which supplied four 800 MW Francis turbines to the Xiangjiaba plant in 2012-13.50 Alstom also inaugurated a global hydropower technology centre in Grenoble, France, for all of its hydropower R&D.51

Dongfang's (China) production of hydropower turbine-generators was reported to be 4.2 GW in 2013, up 28.6% from 2012. A company highlight for the year was installation of a 770 MW unit at the Xiluodu plant. Harbin (also in China) produced 3.2 GW of hydropower turbine-generators during the year, a decrease of 3.7% relative to 2012.52

The hydropower industry is tackling projects of ever-larger capacity, and manufacturers are setting new records for capacity of individual turbines (>800 MW per unit). At the same time, there are indications of a trend towards reduced reservoir capacity and the development of multi-turbine run-of-river projects, as seen in Brazil. As part of this trend, the industry has been developing more-flexible turbines that can adapt to varying flow rates. The use of multiple in-stream turbines in place of few large ones requires different technology, materials, and expertise.53 Another trend is the rise of regional approaches to system development, including interconnection, and a view of hydropower as complementing other renewable energy technologies.54
