Assessment tool developed for Mekong River Basin

Several multilateral agencies have launched an assessment tool that helps identify the most sustainable sites, designs, and operation rules for hydropower development in the lower Mekong River Basin.

The Rapid Basin-wide Hydropower Sustainable Development Tool (RSAT), unveiled by the Asian Development Bank, Mekong River Commission (MRC), and World Wide Fund for Nature (WWF), allows for hydro projects to be assessed in a basin-wide context rather than on a case-by-case basis, its developers report.

The tool uses existing social, environmental, cultural, economic, and financial information about a river basin to make the assessment.

RSAT seeks to enhance existing tools and processes such as Environmental Impact Assessments and Management Plans rather than replacing them, and works by bringing together different sectors and institutions.

It can be used as a checklist for preliminary assessments, a framework for risk assessment, to facilitate dialogue among different groups and identify capacity-building needs, for training and for skills development.

Germany, Finland, and the USA are providing financial support for the initiative.

First turbine operating at Son La in Vietnam

The first of six turbines at Vietnam’s US$2 billion 2,400 MW Son La station has been grid connected.

Elsewhere, groundbreaking has been completed for the US$1.8 billion, 1,200 MW Lai Chau project, regional media report. Located in Lai Chau Province and owned by EVN, it is expected to start generating in 2017.


Lifting the curtain on Russia’s hydro

A series of contract developments appears to signal continued bouyancy in the Russian hydropower sector.

Power Machines, the Russian energy equipment company, has signed an agreement to supply an additional five turbines to RusHydro for the 2,300 MW Zhigulyovskaya GES hydro installation.

Power Machines says it plans to supply the equipment through to the end of 2016. In September 2010, Power Machines signed a RUB11.5 billion (US$408 million) agreement to supply nine turbines for the plant, which is located in Russia’s Samara region.

Meanwhile, Alstom has announced the signing of strategic agreements with Russian energy companies to jointly provide power generation products, including hydropower, with RusHydro JSC.

The agreement covers four key areas: Reconstruction and modernization of the Kubanski cascade; cooperation on development of hydropower; cooperation in R&D, and investment; and local manufacturing of hydropower equipment in the Republic of Bashkortostan.

The Kubanski cascade upgrade includes installation of a new instrumentation and control system, as well as a site security system.

And, in another development, RusHydro has now consolidated a holding of about 25% of the 6,000 MW JSC Krasnoyarsk, the second-largest hydro project in Russia. The deal was carried out through a swap of 4.53% of JSC RusHydro’s shares from the balance of JSC Hydroinvest, a subsidiary of JSC RusHydro.

Acquiring this stake will create operational synergy between the Krasnoyarsk plant and RusHydro, and more efficient cooperation between Krasnoyarsk and retail company JSC Krasnoyarskenergosbyt, RusHydro said.

In related news, Russian group Technopromexport has signed a contract to buy equipment for the construction of the 22 MW Polotsk plant in Belarus. Czech firm Mavel is expected to supply five turbines.

China’s 2,600 MW Changheba approved

In addition, China has been working to dam the Brahmaputra River in Tibet to begin construction of a 510 MW project, regional media reports. This is the first major dam on the Brahmaputra, and China has called it a landmark hydropower generation project for the autonomous region’s development.

Hydropower on the increase in the UK

There has been a six-fold increase in the number of hydro projects planned in England and Wales since 2008, the government’s Environment Agency (EA) announced.

That number is likely to rise again this year as the application process to install hydro schemes is simplified. In 2010, licenses were granted for 65 hydro schemes, compared with 10 in 2008, the EA said.

This year, it will also be more straightforward to make an application, with EA teams providing early advice to help developers produce well-designed, sustainable schemes, they say in a statement.

The EA has been working with industry, anglers, non-governmental organizations, and landowners on ways to improve the permitting process. These improvements, implemented in response to the growing interest in hydro, will not need any changes to the legal framework supporting the various required permissions, the government says.

About 350 hydropower schemes are currently licensed in England and Wales, and EA estimates that this number could rise to about 1,200 by 2020.

Zambia raises hydro capacity plans

Following on from initial studies, Zambia has upgraded the capacity of its planned Kafue Gorge plant to more than 700 MW, from the originally planned 600 MW.

Construction of the US$1.5 billion plant is now expected to start by June 2011 and be completed as planned by mid-2016. Developers are expected to borrow the initial investment of US$1 billion from China, with the remaining US$500 million required coming from the equity partners in the development.

Elsewhere in Zambia, the power supplier to the country’s mining industry is moving forward with plans to build the 40 MW Kabompo Gorge project on the Kabompo River in its North-Western Province.

Copperbelt Energy Corp. (CEC) said it completed preliminary investigations to support preparation of tender documents for the project.

A 2008 government-awarded development concession for Kabompo Gorge was won by CEC and Tata Africa Holdings Ltd., a unit of India’s Tata Group. The project is said to include a dam and water tunnels, a power station, an 80 km transmission line to the nearest grid substation, employee housing, and other facilities.

Brazil ties up with Tanzania in major hydro plant development

Tanzania is planning to construct a US$2 billion hydropower plant in partnership with Brazil.

According to wire service reports, officials from Tanzania held talks with their Brazilian counterparts in Sao Paolo in 2010 on the construction of the proposed 2,100 MW Stiegler’s Gorge station, in Tanzania.

Producing at a cost of about 2 US cents/kWh, the plant would also help to control flooding in the Rufiji area and create a reservoir with a capacity of 34 billion m3 to supply Dar es Salaam and other regions, wire reports indicate.

The government is considering funding options, such as concessional loans, private investment, or state financing.

Brazil will provide the technology to build the plant, with the feasibility study to be updated in 2011 and the first of three 700 MW turbines to be installed in 2012. Full project completion is projected for 2015.

Pumped-storage plants move ahead

German firms RWE and RAG have signed a letter of intent to co-develop integrated pumped-storage and wind projects at RAG’s coal slag heaps in North Rhine Westphalia.

A pilot project is proposed at RAG’s waste dump at Halde, near Hamm-Pelkum, with detailed planning beginning as early as 2011.

The concept would integrate intermittent wind output with the flexible response of pumped-storage hydro by pumping from a low-lying reservoir to a reservoir on top of the waste heap, some 50 meters higher up.

An 18-month timeframe has been outlined for the companies to examine wind conditions, permitting issues, and costs for the project.

Elsewhere in Germany, utility group E.ON AG plans to invest about €250 million (US$328.8 million) to expand the Waldeck 2 pumped-storage project.

E.ON will begin building a new 300 MW plant next to the existing Waldeck 2 facility in 2012. Like Waldeck 2, the new plant will have an underground turbine room.

Construction is expected to take four years, with the new capacity entering service in 2016. After completion of the new plant, the Waldeck site will have a capacity of about 920 MW, the company said.

In a related storage development, Voith Hydro, leading a consortium with Siemens Portugal, has secured a €122 million ($161 million) contract from Energias de Portugal to supply the complete electromechanical equipment for two reversible pumped-storage units at Portugal’s Venda Nova III project.

Voith Hydro will supply two variable speed pumped-storage units, each rated at 380 MW in turbine mode, as well as two asynchronous motor generators rated at 420 MVa, and other equipment.

As consortium leader, Voith Hydro is responsible for the engineering, supply, and commissioning of two vertical Francis turbines with a rated capacity of 51.8 MW each, as well as generators, inlet valves and plant control systems. The contract’s value was not disclosed.

Located on the Kizilirmak River in Corum province, Kargi is Statkraft’s second plant in Turkey. It is being developed by wholly-owned subsidiary Akel Enerji A.S.

Meanwhile, Turkey-based IC Ictas Holding is reportedly set to invest US$1.14 billion in 17 hydro plants in Turkey with a combined capacity of 510 MW.

The construction of four of the hydro plants has already been completed, wires reports indicate.

IC reportedly said that half of the investment was secured in loans, having recently announced signing of a 13-year loan accord with two Turkish lenders for US$253 million, which it said will be used for the Bagistas plant and dam project in eastern Turkey. Total investment for the project is estimated at US$338 million.

Brazil developing hydro projects

Initial construction work for the 11,200 MW Belo Monte project in Brazil’s Amazon has been approved by Brazil’s environment agency, Ibama, wire services report.

To be built on the Xingu River in the state of Para, Belo Monte is expected to begin producing in 2015, at a cost of about BRL20 billion (US$11.2 billion) in development.

In August 2010, Brazilian President Luiz Inacio Lula da Silva signed the concession contract for construction of the project. Norte Energia, the consortium that won the auction, is made up of state-run utility holding company Eletrobras, Brazil’s second-largest pension fund, Petros, and several local construction companies.

Elsewhere, Brazil’s Parana state power firm Copel has signed the concession agreement with the Brazilian mines and energy ministry to build and operate the 300 MW Colider project, news agencies report.

Copel will invest about BRL1.3 billion ($778 million) in Colider, which will be located in the Brazilian center-western state of Mato Grosso. The plant is planned to come online in December 2014.

Copel won the project in a government auction, apparently offering the lowest power rate at some BRL103.40/MWh ($62.80/MWh), Business News Americas had previously reported.

Another Brazilian state-run power company, Eletrobras Furnas, says it expects to launch test operations at the 334 MW Simplicio project in the first quarter of 2011.

The BRL2.2 billion ($1.2 billion) facility — in the state of Minas Gerais — is owned and operated by Furnas, which was granted a BRL1 billion ($608 million) loan by federal development bank BNDES in 2009.
