COzero Case Study: Western Suburbs LC


Western Suburbs Leagues Club registered their interest to participate in COzero’s demand response trial program. They were notified at 12:00 pm on the 14th of January, 2016 about an impending demand response event to occur that day between 2 and 3:30 pm. Due to high temperatures across the state, the electricity market in NSW experienced an extreme surge in prices with the dispatch price hitting $13,800 per MWh for 10 minutes.

The Leagues club responded by cutting usage and activating their 700 kVA generator for the 1.5-hour period. In the outlined time, a total grid reduction of 1,215 kWh was attained. For their participation, a payment of $1,568 was made to the club. If the spot price had stayed at the maximum level as was expected, up to $10 per kWh could have been paid out.

Because of their on-site generation, operational impact on the site was kept to a minimum. The demand response event also allowed for the site manager to conduct a working test of his generator, which is considered good practice for equipment of this size.
