From Wikipedia, the free encyclopedia
Inga Falls

This is a history of the Inga dams, chronicling the various studies, plans, and projects that have aimed to harness the energy of the Congo River at the site of the Inga Falls, located north of Matadi in the Democratic Republic of the Congo. The immense potential of the Inga Falls was recognized in the early 1900s, though the first major hydroelectric project, initiated by the Belgians, did not come until the late 1950s. Two dams were built at the site during the rule of President Mobutu Sese Seko: Inga I was commissioned in 1972 and Inga II in 1982. Since then proposals have been put forth for an Inga III as well as a Grand Inga, which if built, would be the largest hydroelectric facility in the world.

Early study

The hydropower potential of the Congo River was recognized quite early on, at a time when colonial control was kexpanding over Africa and rivers were first being harnessed to generate electricity. One early report on this potential came via the United States Geological Survey in 1921; their findings concluded that the Congo basin in its entirety possessed “more than one-fourth of the world’s potential water power”. Regarding the Inga Falls location specifically, this was highlighted just four years later by the Belgian soldier, mathematician, and entrepreneur Colonel Van Deuren. He would continue survey work around Inga Falls, and during the 1920s and 1930s there was some movement towards further study of the area’s potential, yet the outbreak of World War II and the dissolution of one of the private groups involved in the Inga exploration put a temporary end to focus on the site. Van Deuren’s legacy involved initial recognition of the site’s importance, and a nearby valley now carries his name.

Belgian plan

[edit]

Despite the lack of progress during and in the immediate aftermath of the Second World War, the tantalizing possibilities offered by the Inga Falls remained prominent in engineers’ minds. The 1954 book Engineers’ Dreams listed a host of massive projects that could theoretically be accomplished (among them the future Channel Tunnel), the largest being an Inga Dam that would create a lake stretching into the Sahara Desert.[1]

Before Congolese independence, the Belgians still harbored the hope of constructing a massive Inga development project to generate electricity for heavy industry.[2] Among those industries discussed were “aluminum, ferro-alloys, the treatment of ores, paper, and a plant for the separation of isotopes.”[3] Their vision, at least publicly, was bold, with one authority comparing the potential industrial development in the Congo to the German Ruhr.[3] There was an important American connection the project in the form of Clarence E. Blee, one of five foreigners on a 10-person study of the Inga site in 1957 and the chief engineer of the United States’ foray into federal electrical and industrial development, the Tennessee Valley Authority.[3] This study would play a central role in convincing the Belgian authorities to set an Inga dam in motion.

An Inga development, loosely reported as consisting of a “series of power stations and dams”, was finally passed by the Belgian Cabinet on November 13, 1957, and a group was slated to be created in order to study the possible uses of the project’s electricity and the ways in which to fund it. The Cabinet’s plan was estimated at the time to cost US$3.16 billion and was expected to generate 25,000 MW.[4]

Even as the winds of independence began howling across the continent (an issue not unnoticed by foreigners eyeing its decades long timescale), the Belgians plowed ahead with their plans to dam the Congo.

A report from late April 1958 stated that excavation work would hopefully begin by midyear, with 1964/1965 as the year set to bring the initial stage to completion. Plans called for three stages of construction, beginning with a 1,500 MW plant with a $320 million price tag, then twice that capacity, and eventually the 25,000 MW originally approved. Industrial development would advance in step, helped by a start price of $0.002 per kwh, producing 500,000 tons of aluminum with the construction of the first plant and eventually aiming for a final production goal six times that. An international syndicate named Aluminga, comprised of a number of European and North American firms, was already organizing to realize this. Funding was an issue, especially once the Belgians realized that they could not accomplish such a project alone. Possible investors cited by the press included the International Bank for Reconstruction and Development and the European Investment Bank.[5]

In February 1959 a group of prominent American investors including David Rockefeller visited the Inga Falls,[6] though construction was continually being pushed back from original estimates, then into 1961 or later.[7]

Congolese independence from Belgium did not suddenly erase the importance of Inga development. Belgian authorities were still pushing the project while negotiating independence with Congolese delegates, with Minister Raymond Scheyven proposing a joint Congolese-Belgian company that would fund an Inga dam. This was not a minor idea, but the main project in a five-year Congolese development plan he proposed.[8] That advice was apparently not heeded, as newly elected Prime Minister Patrice Lumumba signed a fifty-year contract with the Wall Street-based Congo International Management Corporation to develop the Congo on July 22, 1960, with an Inga project and associated aluminum production at the top of the list.[9] Yet Mr. Lumumba, caught between internal instability and secessionist movements, was deposed by Army Chief of Staff Mobutu Sésé Seko less than two months later.

Inga I and Inga II

[edit]

Despite the ensuing period instability, rebellions, and UN interventions in the first half of the 1960s, it did not dampen leaders hopes to harness the rapids of the Congo River. From the wreckage of the Belgian departure and the subsequent turmoil emerged Mobutu Sésé Seko, who seized full power for himself in November 1965 and would remain the Congo’s authoritarian president until May 1997. It was during his reign that the first and as of yet only projects were built to generate power from the Inga Falls.

Inga I facility

Inga I was the first project brought to completion. Construction began in 1968 and ended in 1972, leaving a relatively small six-turbine plant generating 351 MW. This electricity was mainly fed to the populated areas around it and downstream; its successor was explicitly for mining activity in the south.

Inga II was the second hydro project built at the site just south of Inga I. Even with just eight turbines, it was built to produce more than four times the power, measured at 1,424 MW. It was completed a full decade after Inga I.

Inga-Shaba power line

[edit]

In order to connect the power generating capacity at Inga with the copper and cobalt mines located near the southern Zambian border in Shaba Province (now Katanga), the project aimed to build the longest High-voltage direct current power line in existence, bypassing local communities and converting into alternate current at its final destination. The groups involved had economic as well as political agendas; while Western investors and the Congolese government wished to support the Shaba mines during a period of elevated copper prices, the government also wanted to consolidate its power over the southern province, and the West had an interest in seeing Congo stay firmly in the anti-communist camp. The cost for the project was constantly revised upward, eventually reaching $500 million over budget. A mix of private and public groups provided the financing, notably Citibank,Manufacturers Hanover Trust, and the U.S. Export-Import Bank, and it was the storied Boise, Idaho-based company, Morrison-Knudsen that was contracted to do the work.

In 1980, the costs of the Inga-Shaba power line totaled 24% of Congo’s debt, which along with corruption, other wasteful spending, and bad decision-making, led to a debt crisis and the intervention of foreign experts. As of 1999, Congo still owed the U.S. Export-Import Bank over $900 million, leaving American taxpayers unpaid. As the Inga-Shaba line neared completion in the early 1980s, many news articles poured scorn on the project. One from the Washington Post juxtaposed its failure with a successful Peace Corps project to improve the Congolese diet, noting that, “the grandiose project has so far turned out to be a white elephant, while the low-key fish-farming endeavor has already made visible improvements in the lives of several thousand people in a similar period of time.” Gécamines, the state-owned mining company in Shaba that was originally founded in 1906 by the Belgians, ended up still mainly using hydroelectricity supplied locally, and thus the Inga-Shaba line found itself being used at a mere third of capacity. Furthermore, the structure itself has been degraded as local peoples have used its metal bars for a variety of domestic needs.

Inga III and Grand Inga

[edit]

One enthusiastic backer of Inga development was South Africa. In July 1999, newly elected South African President Thabo Mbeki gave a speech to the Organisation for African Unity, highlighting development of the Inga Falls for hydropower as an example of necessary development of Africa’s economic infrastructure.[10] For South Africa’s public utility Eskom, Inga fit into a broader plan to turn an interconnected African grid into an electricity-exporting powerhouse, eventually supplying Europe and the Middle East.[11] In 2002 Inga was highlighted by the AU’s New Partnership for Africa's Development (NEPAD)[12] and Eskom was reported to be investigating a $6 billion run-of-the-river type Inga project which would be developed by an Eskom and Hydro-Quebec led consortium of national utility companies.[13]

Such a consortium, dubbed the Western Power Corridor (Westcor) was finally organized in February 2003. Involving five of the region’s major utility companies (Eskom, SNEL, Angola’s Empresa Nacional de Electricidade, Namibia’s NamPower, and the Botswana Power Corporation) it projected initial costs at $1.5 billion for an eventual 44,000 MW run-of-the-river project.[14] A memorandum of understanding for Westcor was finally signed on October 22, 2004, for the construction of a 3,400 MW Inga III.[15] The following February Eskom unveiled a new $50 billion run-of-the-river scheme.[16] That September 2005 a shareholder agreement for Westcor was signed, giving each party 20%.[17]

The DRC appeared to move away from the regional development approach offered by Westcor and instead manage the construction of Inga III on its own. In June 2009 it opened bidding for a $7 billion, 4320 MW Inga III project.[18]
