Hornsdale 2 set for frequency control test

AUSTRALIA: A new programme between the Australian Energy Market Operator (AEMO), the Australian Renewable Energy Agency (Arena) and project developer Neoen will investigate whether the 100MW Hornsdale 2 wind project can provide grid stability services.

In the test, AEMO will remotely control the project to see if it can provide frequency control ancillary services (FCAS) to the national electricity market, the company said.

Usually, FCAS is provided by thermal generators such as coal and gas projects.

"The evolving generation mix in the electricity market is changing the way AEMO operates both the grid and market. This trial will enable us to test new and emerging technologies that could supply services the market will need in future," said AEMO chief executive Audrey Zibelman.

The A$600,000 ($473,000) trial is set to begin in October.

"If successful, the trial will provide a critical proof of concept to the market and investors on the ability of wind farms to provide FCAS," AEMO said.

Neoen's Hornsdale complex is becoming a test-bed for technologies designed to secure Australi's grid reliability, which has struggled of late.

Last month, battery firm Tesla was awarded a contract to supply a 100MW/129MWh storage system to the South Australian grid, which will be charged with electricity from the wind cluster.
