Alstom commissions substation for Baltic Sea wind farm

Alstom has completed the commissioning of an alternate current offshore substation for Baltic 2, Germany’s second offshore wind farm in the Baltic Sea.

The wind farm, operated by German utility Energie Baden-W├╝rttemberg (EnBW), hosts 80 wind turbines feeding up to 288 MW into the grid, providing power to 340,000 households.

The offshore substation transmits the energy from the turbines to an onshore connection point in Bentwisch near Rostock via a 150 kV submarine cable.

The turnkey contract managed by Alstom included the technical development, design and supply of the electrical components, platform construction and transport as well as the offshore installation of a high voltage offshore substation.

Gerhard Seyrling, vice-president of Alstom Grid for Central & Eastern Europe and Russia, said: “The integration of renewable energies plays a key role in the energy transition. With the installation of the offshore substation for EnBW Baltic 2, Alstom has made an important contribution to this transition in Germany. The project opens up another direct access point for wind energy in Germany.”

Siemens in $450m Ethiopia-Kenya transmission link

Siemens is constructing a $450m high-voltage direct current transmission link between Ethiopia and Kenya.

The Ethiopia-Kenya Power Systems Interconnection Project will be roughly 1000 km long and will transmit hydroelectricity.

Siemens said it will also “improve the exchange of energy between the two countries and optimize the use of distributed energy sources in this region”.

Siemens is building the link in a consortium with construction company Isolux Corsan.

The order was placed by the Ethiopian Electric Power Corporation (EEPCO) and the Kenya Electricity Transmission Co (KETRACO). The project is being financed by the World Bank and the African Development Bank, and is scheduled to go into operation by the end of 2018.

Jan Mrosik, chief executive of Siemens’ Energy Management Division, said that the link “is one of the largest infrastructure measures in East Africa”.

He added that the link will make it possible “to expand the AC power grids from Kenya to neighbour countries like Uganda and Tanzania, a development that is urgently needed”.

The bipolar system has a capacity of 2000 MW and will connect the two converter stations located in Kenya and Ethiopia with a direct current +/-500 kV overhead line.

Siemens is supplying the core components such as converter valves with direct light-triggered power thyristors, converter transformers, smoothing reactors, protection and control equipment, as well as AC and DC filters. Isolux is responsible for the construction, installation, and equipment in the converter and AC substations.

Siemens said the project will optimize the use of distributed energy sources in the region.

MHI to build waste-to-energy plant in Singapore

Mitsubishi Heavy Industries (MHI) is to build a waste-to-energy plant in Singapore.

The plant in Tuas will be able to process up to 3600 tonnes of municipal solid waste per day, and will have a power generation capacity of 120 MW.

The plant’s stoker furnace-type incinerators and generators are due to go onstream in the first half of 2019 and will be operated, managed and maintained for 25 years by a consortium comprising MHI and Hyflux, a Singapore water management and environmental solutions provider.

The design-build-own-operate deal for the plant was signed between the Hyflux-MHI consortium and the National Environment Agency of Singapore.

Hyflux currently supplies approximately 35 per cent of Singapore’s water and had been seeking a business partner with which to expand into the waste-to-energy sector.

The MHI Group has built three waste-to-energy (WtE) facilities in Singapore, including the Tuas South Incineration Plant in 2000 which, at 4320 tonnes per day, has one of the world’s largest processing capacities.

In a statement, MHI said that the group “aims to expand in overseas markets by leveraging its WTE business expertise and establishing a business model for the public-private partnerships that have become a major driver of environmental business growth in Southeast Asia”.

APR awarded extension to Myanmar plant

US-headquartered fast-track power company APR Energy has been awarded an extension to operate its 102 MW project in Myanmar.

The original contract for the gas-fired plant was signed in February 2014 and marked the first power pact between a US company and the government of Myanmar following the lifting of sanctions.

The Kyaukse power plant is located south of Mandalay, the second-largest city in a country where nearly 42 million people have no access to electricity.

The turnkey facility was installed in 90 days and is one of the largest thermal plants in the country, providing enough power to serve more than six million people.

After initially commissioning 82 MW in April 2014, APR installed an additional 20 MW during the first quarter this year to help offset the reduction of hydropower during the annual dry season.

APR chief executive Laurence Anderson said: “We are excited by the continued opportunity to help power one of Southeast Asia’s fast-growing economies.

“As the first US power company to do business in Myanmar in recent years, we have been fortunate to have exceptional business partners in Myanmar Electric Power Enterprise and the government. They have been fully committed to the success of this project and the role it is playing to enhance the quality of life for people in Myanmar.”

Aggreko wins Guam 40 MW power contract

Aggreko has won a tender to supply the island of Guam with a 40 MW of emergency power.

The need for the contract arose following an explosion and fire at the Cabras power plant in Piti this summer, which caused the shutdown of two of four units. Guam Power Authority subsequently put out the tender to supplement baseload power to the island’s grid network. Venkie Shantaram, Aggreko’s director of North Asia, said the deal “highlights Aggreko’s ability to rapidly mobilize fast-track, turnkey power solutions”. Aggreko will supply engineering services, transport, fuel tanks, installation, commissioning, engines, on-site operators and decommissioning.

GE signs trio of Indonesia power pacts

GE has signed three power deals with Indonesia, including the supply of a fleet of truck-mounted ‘mobile power plants’ capable of generating 500 MW.

PT PLN Batam, a subsidiary of state-owned electricity provider PT PLN, has selected GE’s aeroderivative gas turbine technology for the fast-track project.

GE will supply 20 TM2500 gas turbines. The truck-mounted turbines run on dual-fuel and GE is currently installing four similar units in Indonesia in North Sulawesi.

GE has also signed two joint co-operation agreements to evaluate the feasibility of developing and investing in power projects using combined cycle technology. The first is with PT Indonesia Power, a subsidiary of PT PLN, for a minimum power target of 500 MW, and the second is with independent power producer PT Cikarang Listrindo, for a minimum target of 1000 MW.

The deals were announced as Indonesian President Joko Widodo met US President Barack Obama. The Indonesian president made his first US visit since assuming office a year ago and the trip was part of an effort to foster closer commercial ties.

Widodo is seeking to accelerate economic growth in the world’s fourth most populous nation by investing in infrastructure and boosting trade, and his goals include increasing power generation capacity by 35 GW by 2019.

With more than 17,000 islands, Indonesia requires smaller and more localized power generation. Every 1 per cent rise in economic output in Indonesia increases energy demand by 1.8 per cent – a factor that Widodo and his predecessors in Jakarta have struggled to overcome in recent years. As a result, local businesses have had to grapple with a growing number of blackouts.

The 35 GW increase that Widodo is seeking represents a massive 70 per cent increase to Indonesia’s existing 50 GW power capacity.
