Heliex signs French and Polish contracts


Scottish company Heliex Power signed two key strategic partnerships at POWER-GEN Europe in Cologne this month.

In the first deal, Heliex – which specialises in steam screw expanders and their applications in the recovery of energy from industrial processes – joined forces with Greenerco Energies Renouvelables, a French company specialising in products for the renewable energy and energy efficiency sector.

The new partnership will allow Heliex to grow its customer base in French territories using Greenerco’s knowledge and experience of the French market.

Professor Dan Wright, Heliex chief executive, said: “We are delighted to be working with Greenerco as our partner in France and the French markets. We are confident that Greenerco’s experience and market reach, together with Heliex’s technology, will be a successful combination in the years ahead.”

Olivier Fruleux, managing director of Greenerco, said: “Energy efficiency and especially industrial waste heat recovery is one of the most critical elements for the emerging low carbon economy.”

The second deal saw Heliex cement a new partnership with Zamkon, a Polish company established in 1989 specialising in industrial fittings and consultancy services in thermal energy to the Polish market. The collaboration between the two companies will grow Heliex Power’s customer base into Poland while adding another significant offering to Zamkon’s need-addressing solutions.

Gemini offshore wind farm reaches financial close

The Netherlands’ Gemini offshore wind farm has reached financial close.

The €2.8bn wind farm is located 85 km off the coast of Groningen. When completed, it will contain 150 Siemens 4 MW SWT4.0-130 turbines – their first deployment at an offshore wind farm – for a total capacity of 600 MW.

Mott MacDonald, technical advisor to the project’s lenders as well as its engineering firm, said it had worked closely with the sponsors and lenders to achieve “the largest ever successful financial close in the wind sector”.

Sponsors include Northland Power, SFS, Van Oord Dredging and Marine Contractors and NV HVC. Northland Power is the principal sponsor and has said it plans to acquire a 60 per cent stake in the wind farm after financial close.

Gemini is planned to power 785,000 households when it comes online in 2017.

Mott MacDonald said it will provide construction and operational monitoring services as the project develops. The consultancy said it had provided input on several aspects of the development, including the use of the longest pair of 220 kV export cables in the world.

Biocat in power-to-gas energy storage project


A commercial-scale, power-to-gas demonstration project has been launched in Denmark by the pan-European BioCat Consortium.

The 1 MW facility will use excess wind energy generated at times of low power demand to produce pipeline-grade renewable gas for storage in the Danish natural gas grid, the consortium said.

Located at the Avedàƒ¸re wastewater treatment plant in Copenhagen, when operational the project will be the largest power-to-gas facility based on biological methanation in the world, with a budget of €6.7m.

Gas production is set to begin by mid-2015 and the project is expected to conclude later that year. If successful, the project will lift the power-to-gas technology to market readiness and allow for market introduction by the beginning of 2016, BioCat said.

Power-to-gas is an energy storage technology that can store large amounts of excess electricity produced in energy systems with high penetration of intermittent renewables (mainly wind and solar energy). By converting electrical energy to chemical energy in the form of methane, energy can be injected into the existing gas infrastructure to a practically unlimited extent, BioCat said.

Aggreko to power Peruvian hydroelectric project


Power rental firm Aggreko is to provide 30 MW of continuous power to a hydroelectric site in Peru.

The Santa Teresa Hydroelectric project, located 3423 metres above sea level, is located in the Cusco region 715 miles from Lima.

The contract represents the largest power offering for Aggreko in Peru to date, the company said.

Project owner Empresa de Generaciàƒ³n Electrica Machu Picchu said it awarded the contract to Aggreko based on the rental company’s reputation for excellence in service delivery and value added solutions, providing the customer with significant savings.

High altitudes were a challenging aspect of the project as they reduce generator output, Aggreko said, resulting in a production loss of 10 per cent for every 1000 metres of altitude.

The company said it offers a minimum power reduction at 3400 metres with just 10 per cent loss. “This project has provided us with a fantastic opportunity to demonstrate the value Aggreko is able to offer our customers,” said Ana Amicarella, Aggreko Americas Power Projects managing director.

“Aside from the fuel cost saving made possible by the advanced technology of our generators operating optimally at high altitudes, we were also able to save the customer time by mobilizing the equipment in just five days, using trailers specially designed for loads of up to 26 tonnes.

“Our team of engineers who will be on site 24/7 are highly experienced and have designed and installed power solutions all around the world,”

Siemens supplies 17 wind turbines for Japanese project

Japan’s largest wind power developer Eurus Energy Holdings has ordered 17 3-MW direct drive wind turbines from Siemens.

The order includes the SWT-3.0-101 turbines, which have a rotor diameter of 101 metres, plus a five-year service and maintenance agreement.

The wind turbines will be delivered to the Eurus Yurikogen wind farm on Japan’s northwest coast, which is planned to be commissioned in early 2016.

“This is going to be our third largest wind farm in Japan. With advanced wind turbine technology, we sincerely hope that the wind farm will contribute to the local community development together with the people in Akita,” said Mitsue Usami, general manager of Eurus Energy’s corporate communications and environmental management office.

Following orders for the Akita Port project in 2013 and recently for a project in South Korea, this latest order from Japan reinforces the increased interest of the Asian market in direct drive wind turbines, Siemens said. The gearless wind turbines have fewer components and rotating parts than conventional turbines.

Compared to conventional technology, the gearless wind turbine has half the components and substantially fewer rotating parts, setting a new standard for efficiency and low operational costs.

Meanwhile, Siemens’ has completed its Andong combined-cycle power plant in Gyeongsangbuk-do province, South Korea.

The 417 MW liquefied natural gas-fired plant is Siemens’ second in Asia with an efficiency greater than 60 per cent, the company said. It is designed for 250 starts per year, with a 30-minute startup time from standstill to full load, Siemens claims.

Siemens and owner-operator Korea Southern Power Co (KOSPO), along with partner GS E&C, completed the project in 24 months. The contract included turnkey erection of the plant and supply of the major components, including one SGT6-8000H gas turbine, one SST6-5000 steam turbine, one SGen6-2000H generator, a Benson heat recovery steam generator and auxiliary systems, plus a 10-year maintenance contract for the main components.

Siemens has three additional combined-cycle plants with H-class gas turbines under construction in South Korea, with a total capacity of 2500 MW.

The plants are scheduled to commence operation in 2014-2015.

“The trustful relationship developed with KOSPO and our partner GS E&C made it possible to execute this high efficient H-class single shaft power plant in a record time with highest quality to support the high power demand in the Andong area,” said Lothar Balling, executive vice president and head of global project management at Siemens’ Energy’s power generation division.
