Angola turns to GE’s ‘power plants on wheels’ to tackle power crisis

GE is to provide six of its trailer-mounted TM2500+ mobile aeroderivative gas turbine packages to Angola.

With more than half of Angola’s population with no access to electricity, the deal is intended to provide the equivalent power needed to supply more than 600,000 homes.

The equipment will be deployed by GE’s EPC partner El Sewedy Power at two power plants in Cazenga and Camama operated by utility PRODEL, which is owned by the Angola Ministry of Energy and Water.

For the first year, El Sewedy Power will develop, build, and operate the plants and then transfer them to PRODEL.

PRODEL’s thermal production administrator Euclides Morais de Brito said: “With these units, we can quickly and efficiently add power where Angolans need it most, while maintaining the ability to redeploy the units if necessary.”

The TM2500+ gas turbine packages can be installed in as little as two weeks. They can run on liquid and gas fuel and can achieve full power within 10 minutes.

Rolls-Royce delivers gas gensets to new Ghana plant

Rolls-Royce has delivered 36 of its subsidiary MTU Onsite Energy’s natural-gas-fired gensets for a power plant in Accra, Ghana.

The Type 16V 4000 L32 gensets produce 1560 kW of power and will feed 56 MW into the country’s grid. The high-speed gas engines will be serviced by MTU Asia in co-operation with MTU South Africa.

The VRA Tema plant is operated by VPower Group and is scheduled to go online next month.

Rolls-Royce said the project is expected to play a significant role in stabilizing the country’s power supply network.

Ghana suffers from a electricity shortages and the country’s Energy Commission has resolved to feed an extra 3000 MW into the grid by 2020.

Major oil and gas fields have been under development since 2007 and since that time these two fuels have been the primary sources of energy within the country.

Andrea Nono, chief executive of MTU South Africa, said: “Our gas-powered engines are particularly well-suited for distributed power plants such as those in Ghana. They offer rapid solutions that can be implemented in a relatively short time and are thus capable of helping to stabilize public power supplies.”

Rool-Royce has also commissioned a 100 MW gas engine plant in Mozambique.

The plant is close to the border between Mozambique and South Africa just outside the town of Ressano Garcia and is powered by 13 Rolls-Royce engines.

The 20-cylinder gas-based engines have the capacity to generate a total of 120 MW and were supplied by Rolls-Royce Power Systems subsidiary Bergen Engines.

Rolls-Royce said that the project is the biggest medium-speed power plant powered by its engines. The plant is owned and operated by the independent power producer Gigawatt Mozambique and it will supply electricity to the national grid through a power purchase agreement with state-owned utility Electricidade de Mozambique (EDM).

Matthias Vogel, vice-president of power generation at Rolls-Royce Power Systems, said: “Our medium-speed combustion engines enable efficient use of natural gas to develop power supply. For countries like Mozambique, this technology solution is an important element in building up national electrification.”

Siemens turbines arrive at Egypt combined-cycle plant

Siemens has marked the arrival of four H-class gas turbines at what is set to become the world’s biggest combined-cycle power plant.

The 400 MW turbines have been delivered to the site of the Beni Suef power plant in Egypt.

Egypt’s energy minister Dr Mohamed Shaker saw two of the turbines being placed on their foundations.

Afterwards he said that Egypt is undergoing an economic transformation and as it embarked on many ambitious infrastructure projects, he said efficient and reliable electricity was essential.

The new plant, located south of Cairo, is due to start supplying its first electricity to the grid as early as the end of this year.

It will initially be operated in simple cycle mode but will be expanded to a combined-cycle plant with the addition of heat exchangers and steam turbines, which will take its total installed capacity to 4.8 GW.

“Egypt’s Sustainable Development Strategy outlines the need to provide affordable, reliable and modern energy services, boost energy efficiency and diversify the country’s energy mix,” said Willi Meixner, chief executive of Siemens’ Power & Gas Division.

“We are proud to be part of this vision and to celebrate another step towards its realization.” He said Siemens’ energy projects in Egypt “are set to transform the power landscape – we are setting the basis for industrial growth and job creation”.

MAN Diesel completes Senegal combined-cycle plant

MAN Diesel & Turbo has completed a diesel combined-cycle power plant in Senegal that is expected to provide the equivalent of 15 per cent of the country’s current electricity consumption.

The 96 MW plant operates with five MAN 18V48/60 engines and a MAN MARC steam turbine. The waste heat from the engines powers the steam turbine, which in turn generates 6.6 MW of electricity.

It is the second plant in Africa to make use of MAN’s diesel combined cycle product package.

The plant, which is 90 km north of Dakar, will supply electricity to the national grid and generate the equivalent of 15 per cent of the country’s current electricity consumption.

GE signs $250m grid substation deal in Egypt

GE has signed a $250m contract to inject 7 GW of power into the Egyptian electricity grid.

The deal with the Egyptian Electricity Transmission Company (EETC) will see GE provide its grid solutions to four substations.

The resulting boost will reinforce the country’s national grid and provide enough electricity to power 6.5 million homes.

The agreement with EETC was witnessed by French president François Hollande and his Egyptian counterpart Abdel Fattah El Sisi.

The contract is part of a Protocol of Co-operation signed during Hollande’s presidential visit to Egypt, as French components make up approximately 50 per cent of the total project scope.

The project is being executed in a consortium with Egyptian contractor Rowad Modern Engineering. A first phase, which includes one of the substations, will be connected to the grid within six months with the remaining three substations completed by the end of 2017.

Egypt’s Minister of Electricity and Renewable Energy, Dr Mohamed Shaker, said: “Egypt’s generation capacity has significantly increased over the last two years. Additionally we’re moving towards a more diversified energy mix which drives us to find ways to boost the efficiency and stability of Egypt’s national grid. Through GE’s advanced technological solutions, we will be able to better manage and transmit power nationwide.”

As part of the contract, GE will also supply a digital data protection system, network management system and telecommunication technologies, which will help connect the substations to the National Energy Control Centre and improve the network’s stability.

Onsite power for South African telecommunications firm

A leading South African telecommunications company has announced plans to run its headquarters entirely with on-site power.

Telkom, the country’s top broadband provider, has begun the first phase of its on-site power project with the installation of a 3 MW solar photovoltaic array covering 1800 carports at its Pretoria campus.

The campus includes office buildings and two data centres, with a total baseload power requirement of around 4 MW and a peak power need of 7.4 MW. A tender for the solar phase of the project was issued in August of last year. The winning firm has not been named.

The second phase of the project is planned to include a trigeneration system, for which the company intends to purchase three 1 MW gas engines.

An environmental impact study will first be carried out to determine the effects of extending a gas line from 3.5 km away, a Telkom spokesman told technology news site TechCentral. And in an interview with the Financial Mail, the same spokesman said the firm is also considering the installation of multiple UPS systems.

The company has said it aims to address the rising cost of purchasing power from state utility Eskom.

Phanes Group opens first African office in Johannesburg

International solar energy developer Phanes Group has opened its first African office in Johannesburg, South Africa.

The office will act as a hub for the firm’s activities both in South Africa and across Sub-Saharan Africa.

Dubai-headquartered Phanes said that its current pipeline on the African continent exceeds 650 MW, including a 150 MW project under development in South Africa.

Phanes Group chief executive Martin Haupts said: “Sub-Saharan Africa is a key corridor of growth for solar and a strategic focus for Phanes Group, as we look to further capitalize on economies of scale and solar power’s increasingly important role in economic development on the African continent.”

From its new Johannesburg base, Phanes plans to firstly target Zimbabwe and Mozambique and then Tanzania, Kenya and Nigeria.

Phanes said that the African office will comprise a five-strong team qualified in engineering, economics and finance with experience in delivering more than 70 projects in 14 African markets.

Wartsila wins deal for Mauritius heavy fuel oil power plant

Wärtsilä is to supply four heavy fuel oil engines for a 67 MW power plant in Mauritius.

The Finnish company will deliver the engines later this year to the St Louis Power Station, which has previously operated on diesel generating sets. The upgraded plant is scheduled to be operational by September 2017.

Economic growth and a growing tourism industry have caused an increase in energy consumption in Mauritius. Wartsila said: “The reliability of the grid is extremely important for an insular country like Mauritius. The modernized power station will provide semi-baseload power, including daily starts and stops, to the local residents and industries.”

Mauritius has set a target of having renewable energy comprise 35 per cent of the total power generated by 2025. “By compensating for the gaps in the intermittent output of renewable sources, this fast-reacting plant will be able to support in renewable energy integration,” said Joost Bos, Business Development Manager at Wärtsilä.
