Cummins launches new spark-ignited genset

The new 150 kW model GGLB spark-ignited natural gas generator set from Cummins Power Generation is designed to provide full-rated standby power for backup and emergency power applications. In addition, every alternator option offers full-rated standby power.

The new generator set features a heavy-duty, 4-cycle natural gas engine that is torque matched to a high capacity AC alternator for handling motor starting loads. An electronic governor provides precise frequency regulation for powering sensitive loads. The unit also accepts 100 per cent of the nameplate standby-rated load in one step, in compliance with NFPA 110, Level 1.

“The new 150 kW model GGLB spark-ignited generator set is both user-friendly and environment friendly,” says Colette Weiser, market manager for Commercial Standby Generator Sets, Cummins Power Generation.

“The basic control system is easy to operate and includes system protection features, digital engine speed control, and transfer switch compatibility. The industrial, spark ignited V8 engine burns clean natural gas for exceptionally low exhaust emissions,” added Weiser.

A wide range of options and accessories is available with the generator set to allow configuration for specific on-site power applications. The optional PowerCommand 2100 generator set control adds microprocessor based features, such as remote start/stop, integrated voltage regulation, alarm and status message display, output metering and auto shutdown at fault protection for high reliability.

Several alternator sizes offer selectable motor starting capability with low reactance. Available permanent magnet generator excitation delivers enhanced motor starting and precise voltage regulation for non-linear loads such as variable speed motor controls and UPS systems. The standard cooling system allows full-rated load operation up to 50°C ambient air temperature. Available weather protective and sound attenuated enclosures permit installations at outdoor and noise sensitive sites.

Unalaska selects Wärtsila for baseload

The city of Unalaska has selected a baseload power plant from Wärtsilä to supply electricity for the Port of Dutch Harbour; a hub of Alaska’s fishing industry.

The company will supply two Wärtsilä 12V32 generator sets for the project, producing a total output of more than 10 MW. Each generator is scheduled to run for about 5000 hours per year and the project is being permitted and designed for a total of four units. The contract value of the project is $4.3 million.

Known as the ‘crossroads of the Aleutians’, Unalaska Island is part of the Aleutian Island chain that extends from the Alaskan mainland into the Bering Sea. It is home to 4700 people and one of the country’s most productive commercial fishing ports, as well as a tourism industry that features pristine vistas, accentuated by active volcanoes and a wide variety of native wildlife.

“The city of Unalaska Utility Department serves the two islands of Amaknak and Unalaska, one of the nation’s most important fishing communities and ecologically unspoiled areas in western Alaska,” said Dick Peck, director of Public Utilities.

“This new power plant will ensure delivery of reliable power to keep the town’s fishing industry productive,” added Peck.

Volvo Penta provides power down under

A total of 24 power generation diesel engines in multiple parallel operations are now running in Western Australia.

Seapower Australia is the Western Australian importer/distributor for Volvo Penta marine and industrial engines. It is supplying the mid-west towns of Meekatharra, Sandstone, Wiluna and Yalgoo with two groups of six 7-litre TAD720GE units, one group of five 5-litre TAD520GE units and one group of seven 16-litre TAD1631GE units.

These groups are actually five separate town site power stations located in the midwest desert region of Western Australia. The engines are synchronized together using electronic digital engine control and are powerful and well balanced to produce a smooth and vibration free operation with low noise levels.

In Australia there are now almost 100 dealers who sell and service the range of Volvo Penta industrial and power generation diesel engines. The company’s engine range has expanded greatly to cover a variety of applications and Seapower Australia has kept abreast of industry developments and professional training in order to encompass this.

GE rental powers NSW

Generating equipment supplied by GE Energy’s rental business has been installed at the Wilga Park power station near Narrabri, New South Wales, Australia, and is producing up to 12 MW of power for the Australian grid.

Under a three-year contract that also includes operation and maintenance, GE provided the equipment to Eastern Star Gas Limited of Sydney, owner of the power station. Natural gas from the Coonarah gas field, west of Narrabri is being used as the fuel for the power plant.

Rental equipment supplied by GE includes twelve 1 MW Jenbacher gas fired generator sets, four step-up transformers, and an 11 kV switchboard and control room. The equipment arrived on the site in March and following installation, was commissioned July 2004.

The project marks the first grid connected application for GE Energy’s rental business in Australia, as well as the first such project for the region and for Eastern Star Gas. Dean Ireland, country executive for GE Energy Australia and New Zealand said: “We are looking forward to other opportunities for our rental equipment and services in Australia’s promising energy industry.”
