General Electric is to provide three 25MW aeroderivative gas turbines to GEL Utility Limited (GEL) in Nigeria.

GEL is to install the trailer-mounted turbines at Nigerian’s National Petroleum Corporation’s (NNPC) state oil refinery at Port Harcourt to overcome chronic local grid outages and generate uninterruptible power. The engines are designed to provide baseload and backup power to support refinery operations.

The 49-year-old Port Harcourt facility is the country’s largest oil refinery and aims to regain full capacity for refining from its present 30% output. It has a total maximum capacity of 210,000 barrels per day.

“This project was not only important in getting the refinery back into full operation, but also to support Nigeria's long-term economic interests by achieving optimum refining capacity," said GEL chief executive Akinowole Omoboriowo.

The chronic power outages have forced Nigeria to import large amounts of refined petroleum to meet the electricity demand. The installation of General Electric’s turbines is to reduce the imports.

The units will start operations this month.

GEL signed a 20-year power purchase agreement with the Nigerian National Power Petroleum Corporation to modernise also two other refineries in the country.

Italy-based Acta and Danish Dantherm Power have teamed up to develop a self-recharging fuel cell based backup power system.

The power solution will be deployed on an island close to the Arctic Circle and powered by a wind turbine.

Dantherm will integrate Acta’s electrolyser, which facilitates hydrogen production, with its fuel cell backup power system in order to meet the requirements for off-grid power in cold and remote geographic regions. It aims to demonstrate the suitability of the system for renewable energy storage applications under harsh conditions.

“We see a significant opportunity for fuel cell backup power systems for remote locations including cold environments, where the ability to generate hydrogen onsite from renewable power sources is a key enabler,” said Paolo Bert, CEO of Acta and added: “We look forward to the success of the partnership with Dantherm and to extending our reach into the telecommunications backup power market together with them."

The shipment is set for September this year.

Acta and Dantherm stated that they are discussing further deployments across the Nordic region.

According to Acta, the supply of fuel cell back-up power systems for telecommunications base stations is a large and fast-growing market, especially in extensively bad-grid and off-grid locations such as in Asia and Africa. Battery sales to the Chinese telecommunication industry are currently valued at $4.7 billion to $7.8 billion per annum, stated the company.

Dantherm is a subsidiary of energy backup supplier Ballard Power Systems and utilises the manufacturer’s fuel cell backup power system for telecom suppliers.

Aggreko powers 2014 Ryder Cup

Aggreko Gleneagles

Power supplier Aggreko is to provide 17MW of temporary power to the 2014 Ryder Cup in Scotland.

The contract includes technical power supply to broadcasters, backup support on location at Gleneagles and air conditioning for on site facilities. Around 40 different temporary structures will need to be powered and cooled.

Aggreko plans to perform its uninterruptible TwinPack generators at the golf event. The generators work together in one container and are designed to minimise sound emissions from power production.

Around 600 distribution boards will be utilised to connect and feed power supplies around the golf course.

"Aggreko has vast experience of providing temporary power and temperature control solutions at golf tournaments. Doing so at the 2014 Ryder Cup, which is on our doorstep and is perhaps higher profile than any previous tournament is a great privilege,” said Angus Cockburn, interim chief executive officer of Aggreko, who stepped into the role after Rupert Soames left to join outsourcing business Serco.

The Ryder Cup is only one of Aggreko’s major event assignments in the past. The company provided power for five FIFA World Cups, nine Olympic and Paralympic Games as well as for four previous Ryder Cups in Europe.

The 2014 Ryder Cup will take place on 23-28 September.

Aggreko backs up Turkish bridge project

Aggreko has won a contract to provide backup power for the construction of the world’s fourth longest suspension bridge in Izmit, Turkey.

The bridge, 50 km southeast of Istanbul, is to be the centrepiece of a new, state-of-the-art highway system linking Izmit and Istanbul.

Under the terms of the contract, Japanese construction company IHI Holding, the project’s leader, is to receive 8.6 MW to ensure that critical safety systems and processes remain operational in the event of any disruption in local grid power. Meanwhile, Turkish engineering and construction firm Sezai Türkeş Feyzi Akkaya (STFA), which is building earthquake-resistant pylons for the project, is to receive 2 MW.

As the bridge is located in an earthquake-prone region, STFA said its pylons will be built into earthquake-resistant concrete foundations that will sit on a layer of gravel on the seabed. Aggreko’s power will run the pumps and other dredging activities involved with fixing the pylons in place at depths of up to 40 metres below sea level. Aggreko said its equipment will be mounted on tugboats for transport to the site.   

“Aggreko is well-known for their high quality service and reliable generators. We were delighted they could provide us with a complete solution and offer the flexibility to rapidly increase our power supply as and when needed. The equipment is fuel-efficient and Aggreko’s customer service is top-notch,” said Umit Kaymaz, deputy manager of administration at IHI Infrastructure Systems.

“STFA has a long history of working with Aggreko. We are satisfied with their speed of delivery and strong business ethics. The time frames of this project were critical as the caissons needed to be submerged as per the schedule without any delays, be they due to unexpected causes or equipment failures,” said Bahadir Imirzaloglu, STFA’s project manager.  

New York’s petrol stations to add backup power

New York’s petrol stations to add backup power

Around 250 petrol stations in upstate New York, US are to receive federal funding to purchase emergency backup power capacity.

The funding was approved as part of the state budget.

Grants from NYSERDA, the state’s energy and development authority, will give participating petrol stations either $10,000 to offset the cost of a transfer switch to connect portable generators in times of need, or $13,000 toward the cost of both a transfer switch and permanent generator.

An additional $3.1m will be made available through federal funding related to Superstorm Sandy.

According to the state a list of petrol stations eligible for the scheme is still in the works, but it will likely include about 250 stations.

In 2013 New York passed the Fuel NY initiative, which required most petrol stations in the heavily populated downstate areas of New York City, Long Island, and Westchester and Rockland counties to install backup power systems by 1 April, 2014 and to deploy and install a generator within 24 hours of losing power during a fuel supply or energy emergency. The move came after 2012’s Hurricane Sandy caused significant fuel shortages in the NYC area.

This year’s state budget creates an additional voluntary backup power scheme for petrol stations in the more rural upstate region if they are within one half-mile of a highway exit or a hurricane evacuation route. Petrol stations can opt into the scheme until October 2015.  

James Calvin, president of the New York Association of Convenience Stores, said, “This plan will provide incentives to gas stations on or within a half mile of exits of interstate highways to voluntarily equip their facilities to remain capable of pumping fuel in the event of a prolonged power outage.”

New York is the first US state to make such a strategy into law.



Web-based monitoring for backup power systems

Web-based monitoring for backup power systems

Power equipment manufacturer Cummins Power Generation has announced the release of its new web-based remote monitoring tool for backup power systems.

The PowerCommand 500/550 software will allow multiple users to monitor generator sets, transfer switches, sensors and output controls from any location, Cummins said. The tool can also start and stop generators and transfer switch tests, as well as reset and acknowledge faults remotely.

Users can monitor data from up to 150 nodes, including genset data such as annunciator, alternator and engine information, and transfer switch data such as source, load and switch connection status. Additional monitoring and controlling capabilities can be provided by expandable I/O modules.

The PowerCommand 500 can monitor and control two devices, for example one genset and one transfer switch in a typical standby power operation, while the PowerCommand 550 can monitor and control up to 12 on-site devices.

Both applications notify users of power system events as they happen, via an email or text message. The software also collects and stores data logs, and its data logging capability can be expanded with a USB memory device or SD card.

The software is compatible with Cummins and third-party power generation equipment and is accessible from any PC or Mac computer, with point-and-click access to its functions.

The new tool will reduce the need for service calls and site visits, Cummins said.
