Generator Source Helps Power Alaska

Alaskan Power Generation

Alaska uses many different types of power to supply electricity to its residents. The state has one coal-fired, six hydroelectric, and one nuclear power plant to supply power. A geothermal power plant supplies power to Chena Hot Springs, Alaska.

Given all the forms of power generation in the state, the grid does not reach remote communities. Small villages often have a grid dedicated to their village only.
Larger fishing communities in the northern Bristol Bay area operate on an electrical grid that connects multiple towns and villages. Many are quite old, with some settled as early as the mid-1800s.

The fishing and tourism industries combined with advancements in technology increased the demand for dependable power. The need for more styles of communication increased as the population increased. The addition of the internet allowed businesses to advertise in a worldwide market.

Larger electrical cooperatives combining multiple towns or villages on a grid can supply services such as electrical power, Internet or cable TV.

Caterpillar Generators Expand Power for Utility in Alaska

Generator Source recently supplied (2) Caterpillar 2250 kW diesel generators to a remote region in Alaska. The engineering team from the customer specified and configured these gensets to sync up with the electric grid. They were interested in adding power generation capabilities to the existing system and allowing system redundancy.

These generators are powered by low-speed, long-life 3608 Caterpillar diesel engines. The engine, generator end and control systems are mounted together on a single skid.

A vertical radiator installed on an accessory stand allows for easy cooling. A pneumatic engine starter eliminates the need for starting batteries and charging system.

Air compressors were supplied to power the air-starting system. We arranged the packing and shipping of the generators. A six-truck caravan left our facility bound for remote Alaska.

Multiple diesel-powered generators connected in parallel is a popular method for fulfilling larger power requirements of a power plant or localized electrical grid.

A redundant design is typically employed with multiple parallel generators. With this design, only generators needed to supply the load are running. As the load increases, additional generator(s) can be placed online. Standby generators are often used in place of online generators when they have maintenance or repairs performed.

We offer a complete line of new, surplus and pre-owned generators. Each generator must pass a 31-point inspection prior to sale. All generators in our inventory are in-stock and ready to ship, Contact Us with any questions.

Story Summary

What generators were supplied to the Alaska utility?
Two Caterpillar 3608 diesel generators, each with a capacity of 2250 kW, were recently shipped to an electric utility in Alaska.

Why were these generators needed?
The generators expand power generation capabilities and provide system redundancy for the utility's existing grid. This helps meet increasing power demands in remote Alaskan communities. Growth in industries like fishing and tourism advancements in technology and communications have created more demand.

What are some key features of these generators?

• Powered by low-speed, long-life 3608 Caterpillar diesel engines
• Engine, generator, and controls mounted on a single skid
• Vertical radiator on accessory stand for easy cooling
• Pneumatic engine starter (eliminates need for batteries)
• Designed to synchronize with the existing electric grid

How is power typically generated in Alaska?
Alaska uses diverse power generation methods including:

• Coal-fired plants
• Hydroelectric plants
• One nuclear power plant
• Geothermal (e.g. at Chena Hot Springs)
• Diesel generators (especially in remote areas)
• Why use multiple diesel generators in parallel?
• This configuration offers several benefits:
• Meets larger power requirements
• Provides redundancy
• Allows for flexible operation (generators can be brought online as needed)
• Facilitates maintenance without disrupting power supply

How were the generators transported?
The generators were shipped in a six-truck caravan to a remote location in Alaska.

What challenges do Alaskan utilities face?

• Supplying power to remote communities not connected to the main grid
• Meeting increased demand from growing industries and technological advancements
• Maintaining reliable power in harsh environmental conditions
• Balancing the need for power with environmental concern
