United Utilities PLC
United Utilities PLC (formally North West Water) provides water and wastewater services to 7 million customers in the North West of England with a total area of more than 14,000 square kilometers. United Utilities operates 192 reservoirs, 453 service reservoirs & water towers, 40,000km of water mains, 1,200km of aqueduct, and 137 water treatment works.


Ceylon Electricity Board (CEB)
Nearly 93 per cent of the total installed capacity in Sri Lanka (both hydro and thermal) is in the hands of the Ceylon Electricity Board (CEB) and only around seven per cent is in the hands of Independent Power Producers. Sri Lanka generates two thirds of its electricity from water, and in 2002, after five years of failed monsoons, major cities were facing 1-4 hour preplanned power cuts due to low water levels.

The Mekong River Commission (MRC)
The Mekong River Commission (MRC) was established on 5 April 1995 by the Agreement on The Cooperation for The Sustainable Development of The Mekong River Basin. The MRC member countries are Cambodia, Lao PDR, Thailand and Viet Nam. MRC maintains regular dialogue with the two upper states of the Mekong River Basin, China and Myanmar. The MRC member countries agree to co-operate in all fields of sustainable development, utilisation, management and conservation of the water and related resources of the Mekong River Basin, such as navigation, flood control, fisheries, agriculture, hydropower and environmental protection.

The Mekong River is the longest river in southeastern Asia. From its source in China's Qinghai Province near the border with Tibet, the Mekong flows generally southeast to the South China Sea, a distance of 4,200 km


Asian Development Bank
ADB is a multilateral development finance institution dedicated to reducing poverty in Asia and the Pacific. Established in 1966 they now have 63 member countries, 2000 employees, and in 2003 approved loans totalling US$6.1 billion. A list of all the energy related projects supported by the Asian Development Bank can be found here.
The Turkish Government
The Turkish Government has gone through a recent program of privatisation and has sold off the operating rights to a large number of power generation and distribution facilities. Turkey does not generate enough power to meet its own requirements and has predicted that by 2010 it will only produce 30% of its demand, the rest being made up through import. 40% of the current installed electricity generating capacity is hydro related. There are 6 principal hydro electric generation facilities in Turkey:
Tortum: 5.8MW x 2, 7.7MW x 2
Hirfanli: 32MW x 4
Hasan Ugurlu: 129MW x 4
Keban: 183MW x 8
Kesikkopru: 46.2MW x 2
Gokcekaya: 104.4MW x 3

Itaipu
Itaipu in Brazil is the world's largest power plant of any kind. The plant is located on the Parana River 14 km north of the International Bridge linking Foz do Iguacu, Brazil and Ciudad del Este, Paraguay. Planning for the project started in the 1960s, construction started in January 1975, and the first of eighteen 700-MW turbine/generators went on-line in May 1984. The total direct plant investment is estimated to be $11-bil. In 1997, Itaipu generated a record 89.2 TWh of electricity and provided 79% of Paraguay's total electricity supply and just over a quarter of Brazil's total supply. Itaipu was an immense undertaking. The main dam has a height of 196 m and the construction required 12.6-mil cubic meters of concrete -- 15 times the amount used in the Channel Tunnel -- and 478,000 tons of steel. The various dams have a total length of 7,744 m while the water flow through each turbine penstock is equivalent to the normal flow of the Seine River in France. Itaipu was going to be even larger, but plans to add two more 700-MW turbines at a cost of $190-mil were canceled in June 1999.

Tanesco
Energy from water (hydro) is a very important source of electric power in Tanzania currently accounting for about 67% of total available installed capacity. Tanzania’s total hydroelectric energy potential is in excess of 4.7GW of installed capacity or about 3.2GW of firm capacity. Of this potential installed capacity only about 5% has actually been developed.

London Economics is committed to providing world-class standards of advice and services to private and public sector clients.
NRA
The National Rivers Authority was formed in 1989 when the ten British water authorities were sold as water service companies to oversea the management of water resources, including rivers and river water quality, fisheries, leisure and pollution control. The National Rivers Authority was Absorbed into the new Environment Agency.
Environment Agency
The Environment Agency has responsibility across England and Wales for the protection of the environment. This includes issues relating to agriculture, rivers, air quality, industrial pollution to land air and water, solid waste, flooding, fisheries, nuclear power and water resources.
The United Nations development Programme (UNDP)
The United Nations development Programme (UNDP) operates amongst many, the Electricity Network Rehabilitation Programme (ENRP) across the North of Iraq. The programme includes major repairs to Northern Iraq's two major dams and associated hydro power stations, as well as a survey of the electrical distribution network and preparation of a maser plan for rehabilitation and expansion.
