AUSTRALIA’S ENERGY CHALLENGES

The need for capacity firming

Renewable energy sources are indeed part of Australia’s future, but making sure that renewable energy sources are providing stable, dispatchable power is no easy task. GE’s aeroderivative gas turbines offer an efficient solution for quickly stabilizing the grid, and providing a firm offtake solution for your customers.

The growth in renewables and the expected retirement of large baseload coal-fired power stations is creating an opportunity for flexible gas-fired power plants and capacity firming solutions. The quick rise of solar and wind power has led to an accompanying decrease in reliability and security of supply on the grid, and with the Australian Energy Marketing Operator (AEMO) forecasting an increase in the risk of load shedding events over the next few years, the need for a dispatchable solution is clear.

Also known as grid firming, capacity firming is a vital characteristic for any power generation system. While renewable power generation sources are now essentially competitive with traditional power generation alternatives, they can have adverse system impacts if they are not carefully integrated into the grid. Wind and solar are typically non-dispatchable and their nameplate capacity does not always align with the required power demand.

INTRODUCING

Aeroderivative gas turbines for grid firming

Born from aviation technology, GE’s aeroderivative portfolio features highly flexible and mobile technologies for use in a wide variety of applications, including utility generation, district heating, mobile power, and of course, grid stability. GE’s aeroderivative gas turbines have a wide range of characteristics that makes them exceedingly suitable for capacity firming.

Fast-start

FAST START

With around five minutes to ramp up from start-up to full power, you can get on the grid quickly. Typical medium-speed reciprocating engines have a ramp rate of about 5 MW/min, but aeroderivative gas turbines have a nominal ramp rate of around 50 MW/min, providing a much faster frequency control response for better grid support. Aeroderivative turbines are designed for high cycling capability, allowing multi-day start/stop cycles.

Added-frequency-support

ADDED FREQUENCY REGULATION

GE aeroderivatives provide better grid frequency regulation than reciprocating engines, with pro-boost, a short duration power boost, and synch condensing capabilities (clutchless synch condensing configuration is available).

Flexibility

FLEXIBILITY

A fast ramp rate (~50 MW/min), high part load efficiency, and a low minimum load and deeper turndown all contribute to aeros’ flexibility and their ability to quickly work within an intermittent grid.

Smaller-size

SMALLER SIZE

The size of our aeroderivative gas turbines (as compared to larger heavy-duty machines) makes them good for both a smaller land footprint and a more flexible way to either add to your current power setup or create a modular layout.

Quick-install-time

QUICK INSTALL TIME

Our TM2500 can be installed in less than three months, and our LM6000 and LM2500 can be up and running in six, helping you get the dispatchable power you need, either as a bridging solution or for an emergency fast-power situation.

lowered-water-dependence

LOWERED WATER DEPENDENCE

Access to water is a challenge in Australia, making our dual-fuel DLE (Dry Low Emissions) combustor technology a great solution. As the name suggests, DLE helps you meet NOx emissions requirements without the need for water or steam injection.

Flexibility

FUEL FLEXIBILITY

Aeroderivative gas turbines can operate on a wide variety of fuels. As standard they can use natural gas, diesel and aviation fuel, but can also be configured to operate on fuels such as naphtha, LPG, ethane, ethanol, bio-diesel and others.
