The RRO rate changes each month
The RRO rate changes with the market cost of electricity. Even if your usage stays the same from month to month, your bill can go up or down as the market price of electricity changes.
The RRO rate changes due to market forces beyond a single energy provider’s control. Fluctuations in supply and demand, weather, electricity generation plant maintenance and the cost of fuel to operate generation plants are just some of the factors that can affect the market price of electricity.
Although fluctuations in electricity markets are normal, recently there has been a general trend of increasing electricity prices.
