Answer

There are many factors that impact on the price of electricity including the availability of renewables on the system. In periods of high wind, prices tend to drop with the highest prices associated with a lower wind forecast.

When renewable energy is available on the system, it has a dampening effect on the wholesale price, pushing down the price set by traditional thermal generation.

However, renewable energy availability is intermittent and the system remains reliant on traditional fossil-fuelled generation to ensure security of supply. Therefore, the predominant influence on electricity prices remains the wholesale cost of fuel.
